Description

Material structure with flame-resistant material, in particular for

High visibility clothing

The present invention relates to a material structure, in particular for producing a material web for clothing, which at least partially contains a flame-resistant material, and which can be used in particular for the production of warning and protective clothing. Furthermore, the present invention relates to a garment with such a material structure.

Workwear that is highly visible, such as warning clothing that is at least partially provided with a particular signal color, is needed in a variety of fields. The use of signal colors serves, in particular, for the purpose that the wearer of workwear is highly recognizable in a wide variety of environmental conditions by the luminous and color effect of the signal colors. In addition, workwear often requires additional protective function, such as flame resistance, to protect the wearer of the workwear from adverse environmental conditions, such as fire and heat. Areas of application of such warning or protective clothing can be found in particular in fire brigades or civil protection.

The European standard EN 471 (2003) specifies requirements for the "conspicuous" material to be used for such warning clothing. In particular, it states that the conspicuity is enhanced by a high contrast between the clothing and the background before which the clothing is seen and by large areas of the defined conspicuous material. This includes three color areas for background material and material with combined properties. Furthermore, requirements for the color behavior of the materials used are specified. For this purpose, color requirements for background material and material with combined properties are specified in a color table, the standard color value components and luminance factor for the three main signal colors fluorescent yellow, fluorescent rende orange-red and fluorescent red determines. For warning clothing to conform to the requirements of EN 471, their color values and luminance factors must be within the value ranges specified in this color table.

The production of such warning clothing can be done in different ways. On the one hand, the substance or the outermost material layer of the fabric used for producing the warning clothing can be dyed with the signal color itself, in order to achieve a comparatively large-surface coloring of the clothing with the respective signal color. However, this method of preparation is only suitable for certain materials and compositions of materials. In particular, material structures for heat- and flame-resistant clothing, which are made of specific fibers or yarns such as aramid, and which are particularly suitable for fire protection clothing, can be dyed very difficult or not at all with the usual dyeing methods with signal colors. For this reason, warning clothing is either not available for these applications or it is possible to provide assistance such as, for example, the sewing of fluorescent strips in strategic locations of the protective clothing. Another possibility is to make certain compromises in production and color with the disadvantages such as rapid yellowing of fluorescent colors or use of a non-compliant color EN 471.

Another option is to provide protective clothing suitable for use under conditions of fire or heat without the use of signal colors in appropriate facilities, such as fire fighters or civil protection, and to provide warning clothing, such as safety vests, which meets the EN 471 standard and for uses such as accident rescue and the like can be used. However, this is due to the increased procurement costs relatively expensive, also there are sometimes operating conditions, such as firefighting in accident situations in which the protective clothing must meet both heat and fire resistance and warning effect. WO 01/66851 A and EP 1 143 062 A1 describe clothing with permanent soiling resistance, which is at least partially made of a material which, in combination with a brightly colored background material, has a color which meets the requirements of the European standard EN 471 , The fabric hereby consists of yarn material, wherein the threads are substantially completely coated with a silicone coating, but the silicone coating does not completely fill the spaces between the threads. This ensures, on the one hand, that the protective clothing thus produced complies with the requirements of EN 471, and, on the other, that the spaces between them ensure that a certain moisture transport to the outside is made possible in order to increase wearing comfort. The amount of the silicone material and the fluorescent color pigments is chosen such that the requirements of the abovementioned color table specified in EN 471 are met. The surface of the individual yarns is completely surrounded by the colored silicone material, the disadvantage being that the coated material is no longer flame-resistant or heat-resistant as required. In addition, the sticky and stiff-feeling silicone-yarn structure is not always desired.

The present invention has for its object to provide a material structure with at least partially flame-resistant material, which can be used for the production of warning clothing with simultaneous protective function.

The invention relates to a material structure, in particular for producing a material web for clothing, according to the features of patent claim 1 and a garment with such a material structure according to the features of claim 32.

The material structure according to the invention comprises a basic structure, which at least partially comprises a flameproof material, with a first side and a second side, wherein at least the first side of the basic structure is printed with a pattern having open areas through which the

Surface of the basic structure is visible. Here, the pattern comprises a material containing a luminous dye, so that the surface of the first side of the basic structure in combination with the pattern is a color of the material. results in compliance with the requirements of the European standard EN 471.

The material structure according to the invention can be used for the production of flame-resistant protective clothing with a simultaneous warning function, since with the basic structure in combination with the pattern, a signal color of the material structure can be produced, which meets the requirements of the European standard EN 471. At the same time, with the aid of the basic structure, which at least partially includes a flameproof material, a flameproof protective effect of a clothing produced with this material structure is achieved. In particular, in this way a signal color can be achieved, as required in EN 471, which, for technical reasons, can not be achieved by direct coloring of aramid yarns or fibers.

In principle, a coloration of a surface of a material structure in almost every color coordinate is possible in this way. In particular, all color values and luminance factors specified in the color table of EN 471 can be achieved. Therefore, it is not necessary that the basic structure itself meet the EN 471 requirements, as this can be achieved by applying a colored partial coating in combination with the color of the basic structure. By suitable variation of the parameters color / brightness of the basic structure, color / brightness of the patterned coating and the percentage coverage, in principle any color can be adjusted. It is advantageous if the visible side of the basic structure is colored with a light color and the pattern is designed as opaque colored, partial coating.

Furthermore, it is achieved by the material structure that a certain moisture transport is ensured over the open areas of the pattern, so that the wearing comfort is not significantly limited. In the event that the pattern-like coating has no or only low water vapor permeability, a low degree of coverage is generally desirable. For example, the pattern has a coverage of approximately 20 to 80%, in particular 30 to 70%, and for example, a coverage of 40 to 60% of the surface of the basic structure. An exemplary musical ter, which meets the color requirement according to EN 471, is achieved in particular with a honey-yellow aramid textile as a basic structure with a pattern-shaped, bright orange coating, which is designed in particular as a lattice pattern with a coverage of 60%.

However, in another embodiment of the invention, it is also possible to form the pattern as a grid pattern or as a dot pattern. For example, the basic structure contains a yarn or a fiber which may be made of aramid, viscose and / or polyimide. For example, the basic structure is made of an aramid yarn, knitted, knitted or aramid nonwoven fabric and thus ensures a high-grade flame-retardant and heat-resistant protective effect.

The material structure according to the invention is particularly suitable for the production of a garment, and in particular for the production of protective clothing with warning function, in particular of flame-resistant and heat-resistant protective clothing for the fire department, usable. Such a material structure can be used in particular for the production of clothing or parts of clothing such as jackets, coats, pants, shirts, shoes, gloves, headgear or the like.

According to one embodiment of the invention, the second side of the basic structure facing away from the visible side of the basic structure is connected to a watertight, water-vapor-permeable functional layer or is connected to an airtight (windproof), water vapor-permeable functional layer. As a result, in combination, a flame-resistant protective clothing, which is also waterproof or air-tight, but allows a certain moisture transport through the moisture-permeable functional layer to the outside. On the one hand, this increases the protective effect of such protective clothing and, on the other, it does not restrict the wearing comfort due to the additional protective effect.

With the material structure according to the invention, in particular a fluorescent outer material or outer material or outer fabric of a Schutzbeklei- düng be made for example for firefighters, in which the outer material comprises a light colored fabric having at least one flame and heat resistant yarn or fibrous fabric or knitted fabric and the visible side surface thereof is printed with a polymeric material in a pattern having open areas through which the surface of the visible one Side of the outer material is visible. In this case, the polymer material contains brightly colored fluorescent pigments which, in combination with the color of the surface of the visible side of the outer material, result in a color of the garment which meets the requirements of European standard EN 471.

A garment made with the material structure of the present invention may also be reversibly reversible, for example in the form of a reversible jacket, where the pattern-printed side of the base structure can be used both as an upper part or an inner material part of the garment depending on the purpose. When used as an inner material part, the patterned coating could act as abrasion protection against clothing worn underneath. Since very smooth surfaces can be achieved in the material structure according to the invention, additional product properties of a garment can be achieved, such as dirt repellency and abrasion resistance, in particular due to the additional pattern-like coating.

Further embodiments and further developments of the invention are specified in the subclaims.

The invention is explained in more detail below with reference to the figures shown in the drawing, which illustrate embodiments of the present invention.

FIG. 1 shows a schematic cross section through an embodiment of a material structure according to the invention,

FIG. 2 shows a plan view of the embodiment of the material structure according to FIG. 1, FIG. 3 shows a schematic cross section through a further embodiment of a material structure according to the invention,

FIG. 4 shows an exemplary item of clothing with a material structure according to the invention.

FIG. 1 shows an embodiment of a material structure according to the invention. This contains a basic structure 10, which has a first side 12 and a second side 14. The first side 12 is, for example, an outwardly-facing, externally-visible side of the base structure 10. In this case, when using the material structure for making a garment, the side 12 faces away from the body of the wearer of the garment. Accordingly, in this case, the opposite second side 14 faces the wearer of the item of clothing and is not visible from the outside.

The basic structure 10 at least partially contains a flame-resistant material, which is produced, for example, from yarns or fibers, for example aramid yarns or aramid fibers and / or yarns or fibers made of viscose and / or polyimide. In one embodiment, the base structure 10 may be embodied as aramid yarn fabric, knit fabric, knit fabric or aramid fiber fabric. The base structure 10 may include, for example, a textile material to form a textile structure with refractory material, such as yarn or fiber material. It may be formed in a single-layered or multi-layered form (e.g., laminate structure). Aramid yarn can be used to make a woven or knitted fabric. Aramid fibers can be used to produce so-called non-woven fabrics such as nonwovens.

In the present embodiment, the externally visible side 12 of the basic structure 10 is printed with a pattern 20, which is formed by a material 30 with a luminous dye. As can be seen in connection with FIG. 2, the pattern 20 has open regions 50, through which the surface of the side 12 of the basic structure 10 can be seen. The open areas 50 may each include a range in size of 1 to 9 mm ² . For example, the side 12 of the basic structure 10 with a pattern 20 printed with polymer material 30. For example, the polymer material 30 is a silicone, as this is comparatively well colored and forms a good bond to an underlying textile with the flame-resistant material. In this way, a material structure 1 can be produced, which contains a non-combustible mixture of materials, with which the material structure 1 can advantageously be used as the outer material of an enclosing protective clothing.

The polymer material or silicone should have a viscosity which prevents the pattern from running on the base structure, the viscosity must be such that the polymer material can be processed by printing processes such as screen printing.

The pattern 20 can be applied to the basic structure 10 by means of a screen printing process using a screen printing stencil, for example. The pattern 20 may be formed as a grid pattern or a dot pattern, it is formed in the present embodiment as a grid pattern. The pattern may also have any other shape or design if the distances of the pattern have the appropriate degree of coverage and the largest distances within the pattern are not more than 3-4mm. The grid pattern is formed, in particular, from two sets of mutually parallel strips, the strips of the different sets crossing each other and the strips being formed on the basic structure 10 with a height h of 20 to 80 μm. The open areas 50 are approximately square in the present embodiment with a width b that is sized to obtain the desired area of the open areas.

The luminous dye 40, which is added to the material 30, contains color pigments which are less than or equal to 30 percent by weight of the sample 20 thus produced. In particular, the luminous dye 40 has a dye of fluorescent yellow, fluorescent red and / or fluorescent orange (orange-red according to EN 471). The outwardly visible side 12 of the basic structure 10 is colored with a light color, for example with an honey-yellow color, while the pattern 20 is colored as opaque, latticed coating is carried out with a fluorescent dye, as mentioned above. The combination thus results in a color of the material structure 1 which meets the requirements of EN 471 with regard to the signal color fluorescent yellow, fluorescent orange-red or fluorescent red.

According to EN 471, which is hereby expressly included in the disclosure content of the present application, Section 5.1, Table 2, the color values must lie within the color ranges defined by the vertices of Table 2 and exceed the minimum luminance factor required in Table 2. The luminance factor of orientation-dependent retroreflective material shall be on average equal to the requirements of Table 2 as determined by measurements at the two angles of rotation specified in section 7.3. The tristimulus values of the orientation-dependent retroreflective material for both angles of rotation specified in section 7.3 shall be in accordance with the requirements of Table 2.

All color values and brightness values available in the measurement area are averaged to Y (brightness) and x and y color coordinates, respectively. In this case, the luminance factor Y corresponds to the luminance factor β _min according to EN 471 multiplied by 100. A spectral photometer measures the color value components x and y and the luminance factor Y of the material structure 1. The photometer CM 508 from Minolta, for example, is used as the spectral photometer.

According to the invention, the requirements of EN 471 are achieved by applying a colored, partial coating, in the present case in the form of a grid pattern, to the basic structure 10. The basic structure 10 itself, which may be embodied, for example, as a textile containing aramid fibers or aramid yarns, is dyed as far as technically possible, even with a light color. By suitable variation of the free parameters color / brightness of the basic structure 10, color / brightness of the patterned coating 20 and the percentage coverage, it is therefore possible in principle to adjust each color. In order to meet the requirements regarding the signal colors of EN 471, the coating should be opaque and not translucent. The term "covering" describes in this context special a continuous partial coating with a layer thickness between 20 - 80μm, so that the color of the basic structure in the area of the coating is not translucent (covering the color of the pattern).

In the event that the coating has no or only low water vapor permeability, the lowest possible degree of coverage should be sought.

A material structure 1 which meets the color requirement according to EN 471 was achieved, for example, from an honey-yellow aramid textile with a light-orange coating (coverage approximately 60%, lattice pattern). The coating was applied to the textile by means of a screen printing stencil. In addition to screen printing, other types of jobs can also be used, for example to create a pattern in the form of a dot pattern (dot print). In addition to silicone, all dyeable, pasty masses can be used. A pre-coating with adhesive and subsequent application of color pigments to these is basically possible for the production of the pattern.

Since a smooth surface of the material structure 1 based on the smooth surface properties of the pattern material can be achieved with this technical solution, additional product properties such as dirt repellency and abrasion resistance or a strong reduction of the frictional resistance in the wet surface by means of the pattern-like coating 20 can be achieved. When used in a reversible garment, such as a reversible jacket, the coating could act as an abrasion protection against clothing worn thereunder. The abrasion resistance of the coating and the washing resistance of the coating must be guaranteed.

In order to meet the requirements of EN 471 for the signal color orange, the material structure in particular has a luminance factor of Y> 40. For this purpose, it is provided that the visible side 12 of the basic structure 10 has a luminance factor of Y> 35. In this way, in combination with the colored pattern 20, it is achieved that the luminance factor of Y> 40 is achieved for the entire material structure 1. In order to meet the requirements for the signal color red according to EN 471, it is provided in particular that the visible side 12 of the basic structure 10 has a luminance factor of Y> 25. Here, the material structure 1 has a luminance factor of Y> 25.

In order to fulfill the requirements of EN 471 for the signal color yellow, the visible side 12 of the basic structure 10 has in particular a luminance factor of Y> 50. The material structure 1 as a whole has a luminance factor of Y> 70.

In all three embodiments mentioned, it is understood that the color value components for the respective signal color are selected according to Table 2 (values x and y). To this end, corner points of a color quadrilateral are set up from the x and y values in Table 2, the color components of the material structure 1 for the respective signal color within such a defined color quadrilateral having to comply with the EN 471 standard , The x and y values hereby represent x or y coordinates of a coordinate system spanned by x and y axes respectively for determining standard color value components according to EN 471.

A material structure 1 which meets the color requirement according to EN 471 was, for example, made of an honey-yellow aramid textile (265 g / m ² ) with a lattice-shaped luminous orange coating (silicone Elastosil LR 6200 from Wacker Chemie AG, coverage approx. 60%, approx / m ² ). The coating was applied to the textile by means of a screen printing stencil at room temperature and cured in an oven at 150 ° C / 2min.

The material structure formed in this way is flame-retardant. According to the European standard EN 533 (1997), the highest index of flame propagation of 3 is achieved. This means that in the case of the material according to the invention, when exposed to flame, there is no flame propagation, no formation of holes, no burning dripping, no afterglow and no after-burn time of> 2 s. Thus, the material according to the invention complies with ISO 11613 (1999) for protective clothing for firefighters. Thus, a material for protective clothing be provided for firefighters, which has a warning function and provides protection against heat and flames.

FIG. 3 shows a further embodiment of a material structure 1. According to this embodiment, the non-visible side 14 of the basic structure 10 is connected to a watertight, water-vapor-permeable functional layer 60. Alternatively or additionally, the functional layer 60 may also be formed as a windproof, water vapor permeable functional layer. In this context, basically all known types of such functional layers can be used, for example in the form of multilayer laminates. With provision of the functional layer 60, a further protective function of the material structure 1 can be achieved, so that in addition to the abovementioned protective properties, a waterproof protective clothing can be achieved, which nevertheless has a high wearing comfort due to the water vapor permeability.

In particular, two constructions can occur: a) the basic structure is bonded (glued) to the functional layer and forms a two-ply or three-ply laminate; b) the functional layer in the form of a two-ply or three-ply laminate loosely hangs as a liner construction on the inside of the chassis and may be bonded to the chassis at the edges.

Suitable materials for the waterproof, water-vapor-permeable functional layer are in particular polyurethane, polypropylene and polyester, including polyether esters and their laminates, as described in the publications US Pat. No. 4,725,418 and US Pat. No. 4,493,870. However, particularly preferred is stretched microporous polytetrafluoroethylene (ePTFE), as described, for example, in the publications US Pat. No. 3,953,566 and US Pat. No. 4,187,390, and oriented polytetrafluoroethylene, which is provided with hydrophilic impregnating agents and / or hydrophilic layers ; See, for example, US-A-4,194,041. A microporous functional layer is understood to be a functional layer whose average pore size is between about 0.2 μm and about 0.3 μm. The pore size can be measured with the Coulter Porometer (trade name) manufactured by Coulter Electronics, Inc., Hialeath, Florida, USA.

A functional layer is considered to be "waterproof", if appropriate including seams provided on the functional layer, if it ensures a water inlet pressure of at least 1 × 10 -6 Pa. Preferably, the functional layer material ensures a water inlet pressure above 1 × ^{10 5} Pa. The water inlet pressure is to be measured according to a test method. in which distilled water is applied at 20 ± 2 ° C to a sample of 100 cm ^{2 of} the functional layer with increasing pressure The pressure increase of the water is 60 ± 3 cm Ws per minute The water inlet pressure then corresponds to the pressure at the first water on The details of the procedure are given in the ISO standard 0811 from the year 1981.

As a "water vapor permeable" a functional layer is considered, if it has a water vapor transmission rate Ret of less than 150 nVxPaxW ¹ . The water vapor permeability is tested according to the Hohenstein skin model. This test method is described in DIN EN 31092 (02/94) or ISO 11092 (1993).

The term "airtight (windproof)" means that the barrier layer or web in combination with the barrier layer has an air permeability of less than 25 l / m ² / s, in some embodiments less than 5 l / m ² / s ,

Air permeability:

In order to measure the air permeability of a material web (textile), a test device is used which can measure the air flow or flow through the material web. The test specimens are placed between two rings, resulting in a test area of 100 cm ² . Air is drawn through the test specimen at a constant pressure of 100 Pa. The amount of air that passes through the test piece is measured and calculated in l / m ² / s. The test procedure is described in EN ISO 9237. FIG. 4 shows an exemplary garment 70 in the form of an outer garment, for example a warning or protective jacket, which is constructed with a material structure 1 according to the invention, as explained above. In particular, the first side 12 of the chassis 10 forms an upper portion 71 of the garment 70. In one embodiment, the garment 70 is reversibly reversible for use of the first side 12 of the chassis 10 as an upper portion 71 or inner garment portion 72 of the garment.

The term "flame retardant" in the context of this invention means that the material structure has a limited flame spread The European standard EN 533 (1997) specifies performance requirements for the limited flame propagation of materials based on the results of the test according to EN 532 (corresponds to EN ISO 15025 (2003)) Power is expressed by an index of limited flame propagation Three power levels are established: for index 1 materials no flame propagation occurs, hole formation may occur in flame contact - for index 2 materials no flame propagation occurs, hole formation occurs not on the flame contact.

With index 3 materials, no flame propagation occurs, hole formation does not occur in flame contact, there is only a limited afterburning. For firefighting clothing a material with index 3 (according to ISO 11613: 1999) is required.

The term "thermally stable" means that the material structure can withstand temperatures of more than 180 ⁰ C with a time of 5 minutes according to the oven test of EN ISO 15025 (2003).

The following standards are referred to in the present invention: EN 471 (2003): High visibility clothing EN 15025 (2003): Protective clothing, protection against heat and flame, test methods for limited flame formation.

ISO 11613 (1999): Protective Clothing for Firefighters - laboratory testing methods and performance requirements. EN 533 (1997): Protective clothing, protection against heat and flame, materials and material combinations with limited flame spread.

Example material structure

Basic structure:

2 layers of laminate consisting of an aramid fabric with a surface weight of 205g / m ² and the color honey yellow with a luminance factor Y = 50. The aramid fabric is bonded to a water vapor permeable and waterproof porous expanded PTFE membrane (ePTFE) using a standard lamination process. The membrane was made according to US Pat. Nos. 3,953,566 and 4,187,390 and is coated with a continuous layer of water vapor permeable, hydrophilic polyurethane as described in US 4,194,041. To make a 2-ply laminate, the aramid fabric is laminated to the ePTFE side of the coated membrane using a polyurethane dotted adhesive as described in US 4,532,316. The laminate thus produced has a basis weight of 252 g / m ² and is water vapor permeable and waterproof.

From this laminate, the luminance factor and the color locus for the tex- tile layer of the laminate were determined.

Pattern Material:

Silicone LR6200 from Wacker Chemie AG, Germany is mixed with 15% (based on the amount of silicone used) luminescent pigments available light color orange at the company Radiant Color until the luminescent pigments are evenly distributed in the silicone. The viscosity of the silicone used is approximately 20,000 mPa / s.

Method: The dyed silicone is applied to the textile side of the 2-ply laminate by means of a screen printing stencil. The result is a grid structure wherein the individual strips have a height of about 50 microns. The lattice structure on the basic structure is cured in an oven at a temperature of 160 ⁰ C, 2 min. The coated laminate (material structure) has a basis weight of 345 g / m ²

Test methods:

From the pattern the color location (x, y) and the minimum luminance factor (Y) were determined. The measurement is performed with a Minolta CM 508C Spectrophotometer.

The uncoated 2-ply laminate has a sufficiently high luminance factor according to EN 471, but the color locus is far outside the color coordinates for luminous orange according to EN 471. The laminate coated according to this invention, on the other hand, has a color locus that is within the color coordinates of EN471. Thus, the coated laminate exhibits a fluorescent color according to EN471.

The sample prepared above was tested for flame resistance. For this purpose, the samples were subjected to a flame test. The sample was exposed for 10 seconds to areal exposure according to ISO 15025 (2000) (equivalent to EN 532) and edge exposure according to ISO 6941. The sample had both flames and showed no flame propagation and no hole formation (Index 3) Test Methods:

Color location and luminance factor

The color location and the luminance factor are measured in accordance with point 7.2 of EN 471 (2003) using a Minolta CM 508 spectrophotometer. Each sample is measured, including the underlying materials processed during fabrication. This means that under each sample a functional layer in the form of a 2-layer laminate liner consisting of membrane and textile support material is arranged. The membrane is just below the sample.

When measuring with the spectrophotometer, the values for the x and y axes are read to determine the color locus. Likewise, the luminance factor Y is measured. In EN 471, however, a minimum luminance factor ßmin is specified for each color range. The relationship between βmin and Y is as follows: Luminance factor Y is βmin × 100.
