Textile fabric with visual surface effects as well as method and device for production same

The invention relates to a method and a device with which relatively moving materials are treated with a Pressurized fluid flow to create visual surface effects in the materials, and relates This also applies to the products manufactured in this way.

In the present context, the term "fluid" includes gaseous, liquid and solid flowable substances, which in Form of a coherent, pressurized stream or several streams against the surface of a carrier material or substrate can be directed. The term "gas" here means air, water vapor and other gaseous or To understand vaporous substances and mixtures thereof, which are in a coherent, pressurized stream or in Streams can be directed. The expression “substrate or base material or carrier material” is intended to mean anything Material is referred to, with the surface of which a pressurized fluid flow or pressurized fluid flows can come into contact, to cause a change in the visual appearance of such material.

Albeit for treatment with pressurized fluid streams by means of the inventive Device is particularly suitable carrier material, which is in the form of a textile fabric

is present, in particular a textile product, which thermoplastic Contains yarn and / or fiber components, and in which the treatment of the surface of the fabric with a heated Pressurized fluid flow a thermal modification of the yarns or causes fibers in order to produce a desired surface effect or a desired pattern in the fabric the device can be used quite generally for the treatment of carrier material, if the type of heated pressurized fluid flow or of the carrier material, a visible change in the surface of the carrier material due to contact with the current causes. The treatment fluid can, for example, be a solvent for the base material, or the temperature of the fluid can be chosen so that the individual components of the carrier material with which the fluid flows come into contact, thermally modified or deformed to the to achieve the desired effects.

"Textile fabric" is intended to mean all types of continuous or non-continuous webs or to define them Designate lengths that contain fiber or yarn components, e.g. knitted, knitted, woven, tufted, flocked and Laminated goods or nonwovens, the visual appearance of which can be changed by heated pressure fluids.

It is known to use certain acrylic pile fabrics or acrylic plush fabrics to convey a surface pattern by roller embossing, the pile surface with raised surfaces on the Roller engaged and heated pile fibers are pressed into the base fabric of the textile product and that Surface pattern of the roller is transferred into the surface of the fabric. Such a roller embossing of heated pile fabric however, it is quite expensive because each different pattern to be transmitted to the fabric has its own pattern roller is necessary and the length of the pattern repeat in the fabric is limited by the circumference of the pattern roller. In addition, they can go through Embossing in acrylic pile fabrics is believed not generally to produce patterns by roller embossing thermoplastic fabrics Melt spun yarns such as nylon and polyester pile fabrics

can be obtained because it is difficult to reach the high temperatures necessary for sufficient shrinkage and heat-setting of the yarns are necessary, and because this tends to cause the yarns to stick to the embossing roller.

When dyeing fabrics, it is known to dye a pattern in a moving fabric by continuously flowing Liquid flows of the dye optionally through intersecting air flows, which are controlled according to pattern information, distracted and prevented from hitting the tissue. A device for this purpose is known from US-PS 3,969,779 and U.S. Patent 4,059,880.

It is well known to use devices to introduce compressed air or steam into the surface of textile fabrics, to change the place where fibers or yarns are located or their thermal properties, thus making a change the surface appearance of such tissues is caused. U.S. Patent 3,010,179 discloses an apparatus for Treat synthetic pile fabrics with which a variety by streams or dry steam from pressure vessels on the surface of the moving fabric to be directed to the pile fibers to deflect and reorientate in areas with which the water vapor comes into contact. The fabric is then dried and heated to heat fix the deflected fibers and create a visual effect that is a Imitates fur fur. US Pat. No. 2,563,259 discloses a method by which a flocked pile fabric is patterned therethrough receives that a multitude of air currents is directed into the flocked surface of the fabric before the adhesive is in that the fibers are embedded, finally hardens in order to reorient the pile fibers and certain patterns in them to create. From US-PS 3,585,098 an apparatus for hot air or dry steam treatment of the pile surface is a Textile product known to relax the synthetic fibers and a disorientation and curling of the fibers to cause throughout the tissue. From US Pat. No. 2,241,222 there is one

130037/0672

TA-54 3H

Device with a Yielzahl τοη nozzle openings known from which compressed air or steam vertically into a fluffy The fabric surface is directed to the pile side or the To raise and curl the fluff of the fabric. TTS-PS 2 110 118 Figure 3 shows a manifold with a narrow slot from which pressurized air is applied against the surface of a nub or tuft Fabric is straightened to make the tufts of pas fluffy during textile treatment.

From the above-mentioned patents it can be seen as a whole that compressed air and water vapor can be used to change the surface appearance of tissues are useful, however, these known devices are believed to be insufficient accurate and in the control of high temperature gas flows are not exact enough to be extremely precise and to produce intricate surface patterns with sufficiently sharp delimitations, but that they are generally only for producing relatively roughly defined surface patterns or surface fiber modifications in arbitrary Can be used in an undefined manner. In addition, the devices appear to be more diverse in terms of variety Patterns that can be created with them in the tissues to be limited.

When modifying the surface appearance of a relatively moving carrier material, e.g. a textile product by The application of fluid currents pose many difficulties in controlling the flow, pressure and pressure Direction of currents with sufficient reliability and accuracy to create well-defined and intricate patterns in the fabric. Besides the accuracy with which For a pattern to be outlined, there are also difficulties in effectively handling fluids that are very high Have temperature, the temperature in the pluid streams uniformly over the entire width of a moving tissue must be adhered to. In addition, it is difficult to rapidly activate and deactivate heated currents by means of

130037/0872

U -.- 54 514

conventional valves arranged in the flow lines for the heated fluid.

When heated fluid, e.g. hot air or steam, hits the surface of a tissue in one or more ^ along a elongated manifold exiting at a distance from each other When the stream is applied, difficulties arise in maintaining a uniform temperature of the stream or the currents across the entire width of the distributor. When heated pressurized fluid from a single point along the Length of the distributor is introduced into this and from an elongated, narrow slot or a plurality of openings, which are provided along the length of the manifold to be dispensed cause the different distances the flow of fluid through the manifold and from the heating source of the fluid, different temperature losses in the fluid and, as a result, temperature differences in the out fluid flows exiting the manifold.

When the fluid heat in the streams is used to thermally modify thermoplastic yarns and fibers in the fabrics is used to cause longitudinal shrinkage and molecular reorientation to produce a desired pattern in the Fabric is produced, different temperatures of the currents impinging on the fabric can cause undesirable irregularities in the applied pattern. That's why it is It is important to ensure that all of the currents impinging on the fabric are of substantially uniform temperature. In addition, contaminants contained in the heated fluid can easily individual small nozzle openings of a device for Block application of pressurized fluid and clog, so that the treatment device must be switched off to block the to eliminate. This also leads to a loss of fabric because the device does not properly match the pattern applies as long as there is a blockage.

In the heated fluid inlet ducts to a dispenser for heated fluid, the invention also provides valve devices with the aid of which the pressure fluid flow through individual heating devices of a number of associated heating devices is gradually increasingly adjustable so that the pluid exit temperatures at a given common Energy input levels into the series heating devices can be balanced. This obviates the need for the Force input to be determined individually for each individual heating device, monitor and regulate to maintain uniform temperatures during pluid treatment.

Finally, a device is also proposed for treating the surface of a moving carrier material with a stream or streams of heated pluid directed into the surface of the carrier material, in which the carrier material is supported during its movement over a rotatable roller _y and in which heat transfer fluid passes through the The roller circulates to prevent it from warping or distorting due to the uneven heating of its surface from contact with the stream or streams of heated fluid.

The device has in particular a distributor for heated fluid which is provided with a narrow elongated slot which extends over the path of relative movement of the substrate and in close proximity to that to be treated Surface is arranged. The invention also provides a method and an apparatus for controlling the a plurality of individual heating devices, the heating devices being arranged so that they heated pressurized fluid at a series of evenly spaced locations along the chamber of the Elongated heated fluid manifold to dispense in heated fluid over the entire length of the manifold maintain an even temperature.

The manifold pressure fluid _# as air at a high temperature of for example about 149-371 ⁰ C (300-700 ⁰ F) is supplied and directed out of the slot generally perpendicular to the surface of the moving substrate, wherein the dispensing of the hot air from the slot so is controlled so that it is directed in one or more narrow, precisely limited streams which impinge on the surface of the carrier material in order to cause a desired surface change therein.

In one embodiment of the invention, heated fluid, "for example air, is made using an elongated Intermediate part or a washer or a filler piece, in which notches are formed along an edge at selected intervals, optionally in precisely limited streams directed. The notched edge of the intermediate part is arranged and limited in the distributor slot over its length spaced channels from which the air in a multitude of narrow streams onto the surface of the is directed in relation to the moving carrier material.

The dispensing device for the pressurized cool gas is provided with valves that block the flow of any individual cool gas flow, for example Air can be controlled individually. This blocking device, which acts with cooler gas, can be shared in the distributor slot be provided with the already mentioned spacers or alone to the surface of the carrier material in Matching pattern information optionally a pattern to convey.

130037/0672

The invention also includes a fluid treatment device, by means of which an even distribution of the heated fluid over the entire length of the manifold and the manifold slot is maintained, thereby creating a more accurate and more delineated heat-induced pattern on the substrate to ensure.

In another embodiment, each heater is supplied with pressurized fluid from the environment, e.g., air fed through individual lines, each containing a metering valve for the fluid flow, so that the fluid flow can be regulated independently and precisely by each individual heating device. The heating devices are electrically connected in parallel and connected to a common source of energy, and a temperature sensor, e.g., a thermocouple, is in each Heated fluid outlet or near each outlet from each heater into the manifold chamber arranged. Each thermocouple is connected to a temperature recorder on which the individual fluid outlet temperatures the heating devices can be read.

Given the possibility of fluid flow through each heater gradually adjust to the starting temperature It is no longer necessary to adjust the fluid uniformly, after which the force supplied to each heating device individually to be monitored and controlled separately in order to maintain a uniform temperature over the entire length of the manifold en.

The invention also provides a device for circulating heat transfer fluid through a support roller, with the aid of which a moving carrier material is placed in the vicinity of the heated fluid distributor so that the heated ones Fluid flows can come into contact with the carrier material. The heat transfer fluid ensures a uniform transfer of heat across the surface of the roller and prevents the roller from moving during the Treatment discards or warps due to uneven heating of its surface due to locally limited contact with the heated treatment medium.

The method and the device according to the invention for fluid treatment at high temperature is particularly suitable good for the production of new surface patterns with precisely marked borders in plush fabrics or pile fabrics, which are im Contain melt spinning produced thermoplastic pile yarns. Such patterns were previously available with the known devices not achievable using heated fluids. But surface patterns can also be created in pile fabrics, that contain non-thermoplastic yarn components, e.g. viscose or acrylic yarns. However, here appears the delimitation in the patterns as a whole is not as precisely defined as in the patterning of fabrics, the thermoplastic Contains yarn. The method and apparatus according to the invention is also for the optional treatment of Woven fabrics that contain thermoplastic yarns can be used to create novel crepe or To convey bubble pattern in the manner of relief ware.

As can be seen from the drawing, an unlimited length of a support material such as a textile fabric is used 10 from a supply source, for example a roller 11 by means of driven, variable-speed feed rollers 12, 13 of a pressure fluid treatment device 14, which works with heated fluid, continuously supplied. While the heated fluid is applied to the moving textile fabric 10 is, this is supported by rotating around a support roller 16 and then the tissue treated with the fluid rolled up into a take-up roller 20 with the aid of driven, variable-speed take-off rollers 18, 19 .

A known edge guide can be used along the path of the fabric 21 for the fabric between the feed rollers 12, 13 and the treatment device 14 may be provided to ensure the lateral alignment of the fabric on its way over the support roller 16 to maintain. The speed of the feed rollers 12, 13, the support roller 16 and the take-off rollers 18, 19 is known in FIG Way controllable to give the tissue the desired speed of movement and the desired tensions in the one entering the treatment device 14 through it to generate tissue passing through and exiting from it.

According to FIGS. 1 and 2, the pressurized fluid treatment device 14 includes an elongated discharge manifold 30 for hot gas, which extends across the path of movement of the textile fabric 10 and has a narrow, elongated discharge slot 32 from which a stream of heated pressurized gas, for example Air into the surface of the tissue at an angle generally perpendicular to the surface during movement of the fabric is passed over the support roller 16.

Pressurized gas, e.g., air, is introduced into the interior of the dispensing manifold 30 by means of an air compressor 34 which operates via air supply lines 36 with both ends of an elongated

SammeIröhres 38 is connected for cool air. In the air supply line 36 is a main control valve for controlling the flow and pressure of the air flowing into the manifold 38 40 and an air pressure regulating valve 42 are arranged. An air filter 44 is also provided to help remove contaminants from the air flowing into the cool air manifold 38.

The interior chamber in the hot air delivery manifold 30 is supplied with pressurized air from the cool air manifold 38 through a series 46 of individual electrical heaters 48, two of which are in Pig. 2 are shown. Each heater is connected by inlet and outlet lines 50 and 52, respectively, equally spaced along the length of the manifold 38 and the dispensing manifold 30, so as to heat the pressurized air from the manifold 38 and uniformly along the entire length of the Dispensing Manifold 30. For example, if a dispensing manifold is approximately 152 cm (60 inches) in length, twenty-four 1-kW electrical heaters may be provided in row 46 with heater outlet lines 52 spaced about the length of the manifold .63.5 ^ m (2.5 inches) apart. The row 46 of heating devices can be surrounded by an insulating housing.

In each inlet line 50 to each heater 48 in the series a manually adjustable metering valve 61 is provided for metering the fluid flow so that the throughput of compressed air from Collecting pipe 38 for each individual heating device 48 is precisely controlled can be. Needle valves for precise flow control can be provided as valves, and their use continues is explained in more detail below.

is in the outlet line 52 for air from each heater a temperature sensor such as a thermocouple for measuring the temperature of the air emanating from each heater provided, which is based on the position of a thermocouple

130037/0672

; Ί-Α-> 4: 314

in Pig. 2 is indicated. Each thermocouple 54 is via an in Pig. 2 and 2A electrical wiring indicated by lines 55 with a conventional electrical chart recorder 58 at which all air temperatures in the heater outlet ducts are either visually or with Can be monitored and read using an audible signal. The individual heating devices will be electric Power supplied evenly on demand from a common power source 60.

According to Pig. 2A, the electrical heaters 48 are parallel to the common power source via electrical lines 22 60 connected, in the main power supply line to the individual heating devices 48 is a conventional power regulator 24, e.g. a silicon controlled rectifier, Model 7301 of Pirma Electronic Control Systems arranged. In the interior chamber of the elongated dispensing manifold 30 is approximately in the middle of its length a temperature sensor or a thermocouple 26 (Pig. 2A) is provided, which with a conventional temperature control 28, e.g. a control circuit manufactured by Electronic Control Systems, Model 6700 is electrically connected. The temperature controller 28 is in turn connected to the power controller in a known manner 24 electrically connected so that a desired temperature in the chamber in the dispensing manifold 30 by periodic supply uniform electrical energy to the heaters in the row 46 can be maintained.

Like in Pig. 3, 4 and 6, the dispensing distributor 30 for heated air is composed of an upper and lower wall 62, 64, the screw bolts 66 arranged at a distance from one another by securing means, for example, releasably with one another are connected and delimit the inner chamber 68 in the manifold and have opposing parallel walls 70, 72 of the elongated dispensing manifold 32. Before the heated air entering the interior chamber 68 of the dispensing manifold 30 from the outlet conduits 52 of the array of heaters 48

130037/0672

.: .--. - 1A-54 314

enters, is dispensed from the dispensing slot 32, it is by means of a deflection plate 74, which is located in the rear of the inner chamber 68 forms a narrow elongated opening for the passage of air from the upper to the lower part of the chamber towards the rear and then passed forward in a reverse path through the chamber in the manifold (as indicated by the arrows). The deflection plate 74 thus ensures a more uniform distribution of the air in the distribution chamber and makes it easier to achieve a uniform Maintain air temperature and pressure in the manifold. The baffle 74 is in the inner chamber by means of spacer sleeves 76 which surround the screw bolts 66, supported.

How best from Pig. 4-7 is in the to the lower Wall 64 adjoining wall 72 of the dispensing manifold and at a distance along the length of the dispensing slot distributed a A plurality of outlets 78 for cool air are formed. Each outlet is individual via a flexible conduit 80 and a solenoid valve 82 connected to a collecting pipe 84 for cool air, which in turn via a line 86 (Pig. 2) is connected to the air compressor 34. In line 86 is a main control valve 88, an air pressure regulating valve 90 and an air filter 92 is arranged.

Each of the individual solenoid valves is like Pig. Figure 2 shows schematically, electrically operational with a pattern controller 94 connected, which emits electrical pulses to selected in accordance with predetermined pattern information Open and close solenoid valves. Various pattern control devices are well known that include can be used to activate and deactivate the valves in the desired sequence. Typically can as the pattern control device, a device described in the applicant's US Pat. No. 3,894,413 may be provided.

According to Pig. 4 and 6, each of the outlets 78 for discharging cool air is arranged in the lower wall 72 of the discharge slot 32 so

130037/0672

1A-54 3H

net that from it a single Drucklüftetrom relatively cool air across the discharge slot for heated air towards delivered at right angles to the hot air flowing through it will. The pressure of the cooler air currents is maintained at such a level that the heated air can pass through effectively blocked by the slot in the area or areas in which the cold air flows are emitted is prevented. By activating and deactivating the individual streams of cool air using the solenoid valves 82 according to the information provided by the pattern controller 94, pressurized heated Air that flows through the slot, directed in one or more strictly divided flows so that they are at the desired Place on the surface of the moving carrier material, creating in the surface of the textile fabric 10, when it passes the dispensing manifold, a pattern effect is created. The cooler air that is leaving the Hot air blocks, flows out of the slot instead of the heated air and is distributed around or in the surface of the Carrier material without the thermal properties of the fabric to modify or to significantly disturb the yarns or fibers contained therein. To do this, refer to the arrows in Pig. 4, 6 and 7, with which the air flow is indicated. To ensure that the cooler, blocking air is sufficient The ambient air can also be kept cool in order not to thermally influence or modify the tissue be cooled prior to their delivery from the delivery slot 32. For this a collecting pipe 95 for cooling water is provided, through which the lines 80 for the cool air run.

Blocking devices for the pressurized cool air as described above are used to control the discharge of the heated pressurized gas streams are preferred, but can also other blocking devices, e.g. movable deflection elements or the like, are used in the elongated dispensing slot 32 to optionally prevent the heated pressure from entering the fabric.

When the fluid treatment apparatus is started up, the heaters 48 of the bank 46 are uniformly supplied with electrical power from the power source 60 and compressed air from the air compressor 34 is passed through the heaters. The temperature controller 28 is set to a selected temperature. When the air temperature in the chamber in the dispensing manifold measured by thermocouple 26 reaches the desired temperature setting, the individual exit temperatures of the air in the outlet line from each individual heater are observed on chart recorder 58. If a temperature difference between the outlet of one or more heating devices is detected on the chart recorder 58, the metering valve 61, which is provided in the form of a needle valve, is set by hand for the heating unit or units on which a discrepancy was detected, that the air flow through the heating device is gradually increased or decreased in order to achieve a corresponding increase or decrease in the temperature of the air emerging from the heating device in question. The individual outlet temperatures of the air from the whole series of heating devices can therefore be "compensated" exactly by gradually adjusting the air flow to a uniform temperature, whereby fluctuations in the manufacturing tolerances of the heating devices or slight differences in flow of the heating devices in the fluid flow system can be compensated for. Thereafter, by evenly adjusting the power supply to all heating devices with the aid of the sensor in the form of a thermocouple 26 located centrally in the distribution chamber, a uniform temperature can be maintained over the entire length of the chamber in the dispensing manifold.

The invention also includes a device that uses a heat transfer fluid circulated through the interior of the rotatable support roller 16 (Fig. 1) by which the continuous length of the carrier material on contact with the heated fluid exiting the dispensing manifold 30. It's clear,

130037/0672

that heated fluid currents under pressure upon impact or a flow of fluid onto the surface of the substrate for thermal modification and for causing a change the external appearance of the carrier material, the heated fluid also the underlying, immediately adjacent Surface area of the support roller 16 is heated. This locally limited heating of the support roller can lead to different Thermal expansion and contraction of the roll along its length lead, especially if the moving carrier material is temporarily stopped during the processing operations. This different expansion and contraction of the support roller 16 can lead to warping or warping of the Roller surface near the dispensing slot 32 of the dispensing manifold 30, what causes the carrier material supported on the roll to have different distances from the delivery slot 32 over the length of the slot. This leads to an irregular pattern of the carrier material due to the temperature and pressure differences in the heated fluid streams impinging on the surface of the substrate.

In order to prevent deflections and distortions and the resulting irregular patterning of the surface of the carrier material, a device is provided which allows a heat transfer medium in the form of a fluid to circulate through the rotating support roller 16 during the fluid treatment processes. As FIG. 1 shows, a fluid, for example cooled or heated water, water vapor or the like, is supplied from a supply source 96 through lines 91 which are connected to the central _; hollow support shaft of the roller are connected, passed into and out of the interior of the support roller 16. Devices with which fluid is passed from a stationary supply source through a rotating roller are known and are available on the market, so that no details are explained here. Typical of such a rotary device is, for example, the device sold by the Duff-Norton Company, Charlotte, North Carolina under the trade name 8000 Series Rotary Union Joints.

130037/0672

As already mentioned, cool water can serve as the heat transfer fluid. However, a heated fluid can also be used, e.g. steam or hot water, if the fluid treatment facilitates overall heating of the carrier material shall be. The heat transfer fluid circulating through the interior of the rotatable support roller 16 distributes the localized Heating of the surface of the support roller 16 in the vicinity of the dispensing slot 32 over the entire circumference of the roller, whereby the above-mentioned different thermal expansion and contraction of the roller during the treatment processes avoided will.

To avoid damaging the tissue from the presence of hot gas when the tissue supply is stopped the dispensing manifold 30 for the hot gas with its heaters 48 pivotally supported at 97 and a working piston 98 is provided in order to pivot the distributor with its dispensing slot out of the path of the textile fabric 10.

Fig. 3 shows a first embodiment of a dispensing distributor for pressurized, heated gas according to the invention, in which an elongated adapter or a Intermediate plate 99 with a plurality of elongated, generally parallel notches 100, which are uniformly arranged along one edge of the plate are detachably mounted in the interior chamber 68 of the dispensing manifold so that the notched side edge protrudes into the elongated dispensing slot 32 and with the Walls 70, 72 of the slot a plurality of corresponding discharge channels limited to hot air, from which narrow, isolated streams of pressurized heated gas hit the surface of the moving textile fabric. According to FIGS. 4 and 4, the notches 100 in the plate extend into the inner chamber of the heated gas delivery manifold and form an elongated inlet above and below the plate into each of the of the notched edge of the intermediate plate with the walls 70, of the delivery slot 32 formed delivery channels. The intermediate plate So it is not only used to get pressurized gas in narrow streams out of the

to lead out channels lying at a distance from one another, but rather the edges of the intermediate plate which form the upper and lower openings of the narrow elongated inlets (see Fig. 4) also have the task of catching foreign matter and filter out that may be contained in the pressurized gas, while at the same time allowing continued flow of pressurized gas around the particles and through the channels.

The delivery channels delimited by the intermediate plate and the delivery slot thus direct a large number of isolated, spaced-apart streams onto and into the surface of the moving textile fabric, forming narrow, spaced, generally parallel lines that extend in the direction of movement of the textile fabric on the delivery manifold extend past. If the temperature and the pressure of the heated gas streams are kept at a sufficiently high level, the result in pile fabric, which contains thermoplastic plumbing yarns with which the heated gas streams come into contact, shrinkage in the longitudinal direction, compression in the pile surface and heat setting, whereby continuous, individually separated grooves are created in the textile fabric, which allow the surface of the fabric to be patterned in various ways, which is explained in more detail below with the aid of a few examples. In order to change the groove pattern in the fabric, it is only necessary to loosen the screw bolts 66 and to exchange the intermediate plate provided for another with a different groove size and / or different spacing along the edge of the intermediate plate.

Fig. 8 shows another example of an intermediate plate 102 with irregular spacing between notches 104 along the plate edge, which result in a different pattern that can be worked into the surface of the textile fabric. So it can the most varied of surface patterns can be produced in the moving path with the intermediate plate alone, without an additional one Control of the currents through the above-described

let is provided for cooler pressurized gas.

In Pig 4 and 5 an embodiment of the invention is shown, find in the intermediate plates together with the outlets for cooler compressed gas in the discharge slot 32 to be used in the Textile web to produce a more complicated or more detailed pattern. According to ^ ig. 5 are the outlets 78 in the gutters arranged, which are formed between the intermediate plate and the walls 70, 72 in the slot to the channels selectively by cooler To block gas and thus to achieve a discharge of the hot gas streams with interruptions, so that surface patterns arise, which extends not only across the width of the fabric but also in the direction of movement of the fabric on the dispensing manifold change over.

6 and 7 show another embodiment of the invention in which the patterning of the fabric by using the elongated Dispensing slot 32 and the pressurized cool gas outlets achieved without the use of intermediate plates will. Referring to Fig. 7, by selectively activating the supply of the cool gas stream to some of the outlets 78, in accordance with pattern information of the passage of hot gas through the discharge slot 32 from the cooler gas in corresponding Blocked areas of the slot in order to generate the corresponding pattern in the tissue moving past.

The heated pressurized gas delivery manifold according to the invention can also be used to supply the thermoplastic pile yarns of a pile fabric, which are laid in one direction as a whole, to be lifted evenly. An example of this are pile fabrics, by cutting or slitting the pile yarns of a flat structure in a knitted structure with a double back Creation of two pile fabric layers are made. In such a method of making plush or pile fabrics are mostly the pile yarns of the two fabric layers evenly in a direction opposite to the direction of movement of the fabric inclined during the cutting process.

As indicated schematically in FIGS. 9 and 10, calibration has shown that when moving past a pile fabric with a pile inclined in one direction at the narrow elongated dispensing slot 32 of the dispensing manifold 30 in the direction of movement opposite to. Inclination direction of the pile yarns surprisingly the inclined pile yarns are erected so that they look as a whole at right angles to the surface of the pile fabric, and in this arrangement the pile yarns are heat set by the hot gas jet impinging on the surface of the fabric. 9 and 10 show a carrier material 106 in the form of a pile fabric with pile yarns 108, the direction of inclination of which is also shown, as is the direction in which the stream of hot gas 110 hits the pile surface. As can be seen from the drawing, the gas flow 110 indicated by arrows should impinge on the surface preferably at an angle of approximately 90 ° or more to the direction of movement of the fabric, in order to bring about a uniform fixing of the pile yarn in an upright position. If the fabric moves in a direction other than the opposite of the direction of inclination of its pile yarn or if the flow of pressurized gas is directed differently than within the angles mentioned, the pile yarns are not evenly straightened but either further inclined or arbitrarily disoriented in the surface of the pile fabric.

The use of the device according to the invention for implementation the method described here is to be explained in more detail using a few examples in which the treatment conditions are explained on the basis of textile products that contain yarn components in which the desired surface appearance or pattern is produced. The examples are for illustrative purposes only and are by no means intended to be to be understood restrictively.

The temperature and pressure of the heated air in the chamber in the discharge manifold was at 315 ° C (600 ⁰ F) and 0.42 (6 psig). The dispenser delivery slot was spaced approximately 1.27 mm (0.05 inches) from the pile surface and was provided with an intermediate notched plate as shown in FIG. The spaced dispensing channels thereby formed in the slot were rectangular in cross-section measuring 0.28 mm by 1.57 mm (0.011 by 0.062 inches). The length of each channel extending through the slot was 6.55 mm (0.25 inches) and the channels were 5 »08 mm (0.2 inches) apart from center to center across the manifold.

The hot gas streams impacting the pile surface of the fabric caused the pile yarns to shrink lengthways in the contact areas, as a result of which they were lowered and compacted into the fabric, so that narrow _f elongated, individually stepped grooves formed along the movement path of the surface stretched. Pile yarns adjacent to the sides of the grooves remained essentially unchanged and undisturbed and formed clearly delimited, upright side walls of the grooves. The fabric had a patterned surface appearance ₍ as seen in the photograph of the fabric of FIG. 11.

von Oberfläohenrinnen, with Plorgarne with which the hot air currents had come into contact, had shrunk lengthways into the supporting backs of the tissue. Even the acrylic fabric showed a grooved surface pattern, which, however, did not appear as clearly and one less clear groove delimitation than the fabrics formed from thermoplastic melt staple fibers, such as the polyester and nylon yarn fabrics of the examples.

In the specific examples described above, the processing speed of the pile fabric in the device can be increased if the fabric passes before it the discharge slot from which the hot air emerges is preheated. Typically, the fabric can be heated with known infrared heating devices and / or preheated by heating the support roller 16.

In the above examples, typical operating conditions for the treatment of textile plor fabrics and woven fabrics are described, with which these fabrics are to be given visual surface changes and patterns. It will be understood, however, that the treatment fluid, the temperatures and the conditions of the fluid treatment can be selected differently depending on the construction of the carrier material chosen and the particular surface appearance desired. Excellent results in the generation of patterns in pile fabrics containing thermoplastic pile yarns have been achieved at treatment speeds of approx. 3> 66 - 5> 48 m / min (4-6 yd./min) and hot air temperatures at the outlets of the heating devices of approx. 315 - approx. 371 ⁰ C (600 - 700 ⁰ P) and pressures of approx. 0.14 - 0.49 at (2 - 7 psig) are reached in the distribution chamber. Overall, higher pressures can be used if the delivery slot or the delivery channels formed therein have a smaller cross-sectional dimension. Higher gas temperatures may be desirable when using cool, pressurized gas to control the flow of the hot gas streams.
