Abstract
Continuous process for the mercerizing of yarns effected on the yarn in the form of a bundle, introduced into one or more tubular reactors with an ejection nozzle fed as driving fluid under pressure with the mercerizing solution and then drawn in continuous in one or more drawing units.
Description
- The present invention relates to the treatment of yarns with process fluids to give them the desired characteristics for their final use for producing fabrics or other end-products. In textile technology, the treatment of yarn with reagent liquids is adopted for a wide variety of processings, for different types of fibres such as cotton, wool, silk, linen, etc., which give the yarn the desired characteristics or remove undesired components that reduce their value and the possibility of use. For cotton, for example, this type of treatment can relate to dyeing, mercerizing, bleaching, washing, sizing and so forth.
- In highly prevalent industrial practice, these treatment operations are generally effected with batch operations on discrete lots of yarns, specifically prepared in bobbins or skeins which, after treatment, must be reeled off and re-prepared differently in the production line.
- Batch processing on yarn is generally extremely onerous due to the considerable labour involved, the low performance of the process fluids, the high plant investments and finally as a result of the environmental implications caused by the reagents discharged with the waste water which consequently require further costs to bring the drain water within specification. Batch treatment also has the additional problem of the constancy of the product quality for each processing batch, depending on the variability of the parameters of each single batch processing such as temperatures, times, concentrations, etc.
- The economy, efficiency and constancy of the quality of the yarn treated with continuous processing is therefore a decisive factor for the commercial success of the overall yarn production process.
- To provide a better illustration of the characteristics of the continuous treatment system of yarn with process fluids, in the description of the present invention, reference is made to the mercerization technology—also called mercerizing—under tension of cotton, which represents a typical case of yarn treatment with process solutions; it should be explicitly specified, however, that the continuous treatment system of yarn according to the present invention can also be advantageously used for other types of treatment to be effected on yarns in textile technology.
- Broadly speaking mercerizing consists in the treatment of yarn with alkaline solutions—typically caustic soda, but possibly also with other basic compounds—at a high concentration, followed by drawing. The mercerizing treatment of cellulose yarn improves its mechanical properties, it enhances its gloss and also its adsorption capacity and reactivity towards the finishing products and the affinity to dyes. This enhancements takes place on the single fibers of the yarn in a state of semi-plasticity induced by the concentrated alkalis with which they are soaked.
- In the known technique, mercerizing is typically carried out on skeins of yarn, suitably prepared by means of a reeling step, which are subjected to batch mercerizing and are then washed, neutralized, dried, unwound and reformed in bobbins.
- Proposals have also been made in the known art to treat yarns with mercerizing solutions by first preparing the single threads with winding onto beams, each having hundreds of threads. The threads are unwound from the beams in parallel, passed individually in a sequence of tanks at atmospheric pressure containing soda baths and other treatment fluids, drawn by pairs of rolls and rewound onto other beams or onto single spools.
- The spools of mercerized yarn are then charged onto bobbin winders to be collected into bobbins. These technical solutions are extremely complicated, they have numerous disadvantages and for the moment have not been widely diffused on the market. Soda baths, for example, have large dimensions; this results in high costs for the plant and technical immobilizations and also a low efficiency of the soda baths. The large surfaces of the mercerizing baths are in contact with the air and their sodium hydrate is subject to rapid deterioration by carbonation due to contact with the carbon dioxide in the overlying air. If one of the threads being treated breaks, it would be difficult to detect and recover the skein ends, and in any case the processing must be interrupted.
- The objective of the present invention is to provide a continuous treatment system of yarns with process fluids and, specifically mercerizing fluids, which allows the drawbacks of the systems available in the known art, to be overcome.
- This objective is achieved, in accordance with the present invention, with the treatment system according to the most general definition of claim 1 and for preferred embodiments or possible variants defined in the dependant claims from 2 to 8. The present invention also provides a device for the continuous treatment of yarns, and in particular for mercerization, according to
claim 9 and its dependant claims. - The characteristics and advantages of the present invention for the continuous mercerizing of yarns and, more in general, for their continuous treatment with process fluids, will appear more evident from the following illustrative but non-limiting description, referring to its application to the mercerizing of cotton, according to the plant scheme illustrated in FIG. 1.
- FIG. 1 illustrates the general scheme of the treatment system of yarns with process fluids. FIG. 2 shows an embodiment variation of the mercerizing tubular reactor.
- In the general scheme of FIG. 1, the yarn1 to be treated is fed starting from a series of
bobbins 2 arranged in parallel on specific unwinding creels, not shown in the figure for the sake of simplicity, which release a series of parallel threads which are concentrated in acable laying funnel 3 forming abundle 4 of threads adhering to each other. In principle, the process and the device according to the invention can also operate on a single thread 1, but their industrial application is more interesting—for its productivity and efficiency—with numerous threads, preferably collected in abundle 4 consisting of from 20 to 200 threads or more, depending on their number and characteristics. - In order to increase the solidarity of the threads contained in the
bundle 4 of threads to be processed, according to a preferred embodiment of the invention, insection 6 for the preparation of the bundle of threads, at least oneauxiliary thread 5 with long coils, indicatively having a shed of 200 to 1500 mm, is wound around them, accompanying the bundle during its processing, and is subsequently separated and recovered at the end of the processing line. This expedient, in the case of the breakage of one or more single threads 1, prevents them from not continuing their run through the overall machinery but, with continuous feeding, they accumulate in one of the continuous processing machines. - For example, as shown in FIG. 1, said winding is effected with one or more
auxiliary threads 5 with a high chemical and mechanical resistance—for example made of Kevlar—which are released from one ormore bobbins 8 held by a rotating reel, not shown in the figure for the sake of simplicity, around thebundle 4 and rotating according to the arrow A. An alternative for increasing the adherence between the threads of thebundle 4 can be to apply a slight twisting to the bundle itself, a few twists per meter, assembling the creel of thebobbins 2 on a rotating support, according to the rope-making technique. - The pulling of the threads1 to form the
bundle 4 is effected with the pair of guidingrolls 10, which rotate at a controlled rate and which determine the linear pulling-rate of thebundle 4 of threads being processed, generally at a rate in the order of hundreds of m/min, sending it to the mercerizing reactors. - An important characteristic of the present invention consists in the treatment operation and structure of the reactor in which the treatment of the
bundle 4 of threads is effected with the process fluid which, in the illustrative present description, consists of an alkaline solution of sodium hydrate at a high concentration. This operation is carried out in atubular reactor 15 with a vertical axis and equipped at the beginning with an ejector or a Venturitube 16. - The ejector or Venturi
tube 16 is fed with a pressurized driving fluid consisting of the mercerizing alkaline solution, for example sodium hydrate at 30° Be, which corresponds to about 297 g/l, the bundle ofthreads 4 is guided by adeviator roll 9 and introduced into thereactor 15, with an inlet hole in correspondence with the depression of the contracted vein of the Venturi 16 fluid. The fluid sucks and pulls the bundle ofthreads 4 from thebobbins 2 released at a controlled rate by the initial guidingrolls 10. The bundle of threads passes through thetubular reactor 15, along its axial direction, and exits with the mercerizing fluid from itslower output 17. The inlet pressure of the treatment fluid is regulated so as to obtain, in correspondence with the contracted vein of theejector 16, a driving fluid rate ranging from 12 to 40 m/sec, preferably from 15 to 20 m/sec. It has in fact been observed that, as a result of the high turbulence established in the tubular reactor, high exchange coefficients of material are obtained between the fibers and the fluid, in the intermicelle spaces, and that the contact time can be greatly reduced. The same exchange efficiency has also been observed in the washing and neutralization operations effected in the subsequent tubular reactors. - A
collection tank 18 of the mercerizing solution is situated in correspondence with thelower output 17 of thetubular reactor 15 of the ejector type. The bundle ofthreads 4, on the other hand, is resent upwards by means of adiverting pulley 19 immersed in the liquid collected in thetank 18, it passes through aloose squeezing group 20 consisting of one or more couples ofloose rolls 21 pressed against each other, which squeeze the solution in excess held by thethread bundle 4. Thetank 18 has an overflow mouth 22 which maintains the liquid level inside; the alkaline mercerizing solution is collected from said tank, filtered, reconditioned with respect to concentration and temperature, and then recycled to mercerizing section according to known techniques. - It is known that a typical phenomenon of mercerizing is that the concentrated alkaline solution causes a considerable enlargement and shortening of the cotton thread and consequently of the
bundle 4, with the result that the initial flow-rate in m/min of the bundle at the entrance is clearly reduced at the exit of the reactor. For example, 1000 meters of the bundle ofthreads 4 at the entrance can correspond to 600-700 meters of bundle at the exit. - The ascending bundle of
threads 4, is subjected to the control and regulation of its tension value by means of thecompensator 25, which is illustrated with reference to the subsequent FIG. 2, and is therefore pulled upwards by thedrawing device 30, comprising thedischarge rolls 31, which operates at a linear rate corresponding to the shortening induced in the treatment in thereactor 15, for example at 60-70% of the arrival rate of thebundle 4 at the Venturi 16. Thedischarge rolls 31 also act as gripping rolls for the drawing of thebundle 4 due to the effect of thedrawing rolls 32, situated downstream of the gripping rolls and are rotated with a higher rate than therolls 31, for example at 90% of the arrival rate of thebundle 4 at the Venturi 16, thus recovering most of the shortening induced in the thread fibers 1 and providing the tension necessary for fully receiving the benefits obtained from the mercerization. The yarn is then discharged from the mercerization unit by means of thedirectional deviator rolls 33. - The treatment in the mercerization unit can be repeated once or several times to graduate its effect on the processed cotton. Again for illustrative purposes, FIG. 1 shows a second mercerizing
reactor 15′, completely analogous to the previous one. The same numerical references refer to similar components and having the same function. - Also in the second reaction step, the alkaline mercerizing solution again induces an enlargement and shortening of the threads which form the
bundle 4, so that it is pulled with thedischarge rolls 31′ at a linear rate which corresponds to the new shortening obtained in the treatment in thereactor 15′. The discharge rolls 31′ and the drawing rolls 32′, for example, operate completely analogously to the previous ones and at a linear rate which obtains a tension and induces a drawing with the recovery of length of the bundle of up to 90% of the initial arrival value of thebundle 4 at the Venturi 16. The yarn is then discharged by means of directional deviator rolls 33′. - In the
second reactor 15′, the treatment is perfected and a new shortening of the yarn is obtained, which is again drawn in the intermediate section between therolls 31′ and 32′ and, for example, brought back to the value of 90% of the initial length which it had in correspondence with the initial guidingrolls 10. - After passage in the mercerizing
reactors threads 4 is fed to the washing with water. For example, the washing is effected in several steps, with water in countercurrent and at a decreasing temperature, so that the last washing is carried out with the purest and coldest water and thus using the resulting water, containing the removed soda, for the next-to-last washing, and so on. For the sake of economy, the water coming from the first washing, containing the soda removed in the series of countercurrent washings, can then be used to prepare the concentrated mercerizing solution for being reintegrated in the plant. The illustrative scheme of FIG. 1 shows, to simplify the drawing, two washing steps in countercurrent. - The mercerized bundle of
threads 4, guided by thedirectional rolls 33′, is introduced in the first washing step into theunit 40, by means of the Venturinozzle 41 fed with a pressurized stream of washing water coming from the subsequent step. Analogously to the previous mercerizing reaction steps, thebundle 4 enters the Venturi 41 in correspondence with one of its side holes in correspondence with the depression of the contracted vein of the fluid which sucks the bundle ofthreads 4, creating close contact between the mercerized threads forming the bundle and the washing water. Analogously to the mercerization units previously illustrated, the bundle ofthreads 4 leaves the Venturi 41 together with the washing water which is collected in thecollection tank 42 of the mercerization solution. The bundle ofthreads 4 is, on the contrary, resent upwards by means of a loose divertingroll 44, immersed in the water collected in thetank 42, it passes through asqueezing group 45 consisting of one or more pairs ofloose rolls 46 pressed against each other, which squeeze the solution in excess held by the bundle ofthreads 4. Analogously, thetank 42 is provided with aoverflow mouth 47, from which the washing water is recovered and re-used. - The bundle of
threads 4, rising from the washing unit, is subjected to the control and regulation of its tension value by means of the compensator 50, analogous to thecompensator 25, which is illustrated with reference to the following FIG. 2, and is therefore pulled upwards by thefinal drawing device 51, completely analogous to thedrawing devices final drawing unit 51, situated between the two washing steps, consists of a pair of gripping rolls 52, and a subsequent pair ofdrawing rolls 53, which operate so as to restore, for example, the initial length of the bundle ofthreads 4. The gripping rolls 52 operate at the linear rate with which thebundle 4 leaves the lower part of theVenturi 41. The subsequent drawing rolls 39, for example, are activated, on the other hand, at the same linear rate as that of the arrival of thebundle 4 at thefirst Venturi 16, thus completely recovering the entire shortening induced in the threads 1 and providing the definite mercerizing tension. The yarn is then discharged with the directional deviator rolls 55. - Again for illustrative purposes, FIG. 1 shows a
second washing unit 40′, completely analogous to theprevious unit 40. The same reference numbers refer to similar components and having the same function. TheVenturi nozzle 41′ is fed with a pressurized stream of the purest washing water, whereas the water coming from thesecond unit 40′ is used as feeding in thefirst unit 40. - The bundle of
threads 4 washed inunits neutralization unit 40″ is completely analogous to thewashing unit 40′ and operates again with aVenturi nozzle 41″, this time fed with a pressurized stream of a diluted solution of acetic acid to remove the alkaline residue from the threads of thebundle 4. The same reference numbers inunit 40″ refer to similar components and having the same function asunit 41′. The neutralization solution is collected in theunderlying tank 42″ and is recycled; the pH of the resulting acetic solution is checked in thetank 42″, and its composition is controlled, before being recycled, for any possible corrections to be made to its number and to verify the neutralization trend. - The bundle of
threads 4 washed inunits unit 40″, is then subjected to a complete drying step, for example in the dryingunit 60 with a winding path around the cylindrical surfaces of a series of squeezingcylinders 61 and dryingcylinders 62 heated with diathermic oil. As an alternative, drying with hot air can be effected at about 100° C., after a passage through a Venturi with a depression of around 200 mbar to remove the liquid particles still separated. - The threads1 forming the bundle of
threads 4 thus mercerized are then separated in theseparation unit 70 of thebundle 4, according to an inverse process with respect to that previously effected. - The first step consists in unwinding one or more
auxiliary threads 5 initially wound, which are rewound onto one ormore bobbins 71 held by a rotating reel, not shown in the figure for the sake of simplicity, around thebundle 4 and rotating according to the arrow B, in the opposite direction to the arrow A and with the same winding shed. The threads 1 become parallel again and are no longer constrained in the bundle and can be separated by passing them in their guide-threads 72 to be rewound onto separate bobbins of mercerized thread. - An important characteristic of the present invention is the way in which the thread is impregnated with the process fluid, and essentially in the specific case of the mercerization of cellulose fibers. The impregnation and reaction step is effected in very short times in the
reactor 15, starting in theVenturi 16. In these devices, a high flow-rate is established with respect to the bundle ofthreads 4, and there is a vortical motion and brusque involvement also of the threads inside thebundle 4. As described, the mercerization treatment can be repeated once or several times in subsequent reaction steps, to graduate its effect and then complete the drawing action after the washing, until the desired result is obtained. - FIG. 2 shows an embodiment variation of the reactor with the
ejector 16 forming the first part of thetubular mercerization reactor 15. In this variation, thesingle Venturi nozzle 16 described above, in the mercerization reactor 85, is substituted by several, i.e. two or more Venturi tubes in series along the reactor, in which the bundle ofthreads 4 passes in sequence, from thefirst Venturi 86′ to thesubsequent Venturi tubes 86″, 86′″, and so on. The Venturi driving fluid consists again of the treatment solution: in this particular case the mercerization alkaline solution. In the embodiment illustrated in FIG. 2, theinlet 87 of the pressurized driving fluid in theVenturi 86, are situated at the side, whereas the bundle ofthreads 4 follows, in a straight path, the axis of the sequence of the Venturi nozzles in the reactor 85. The stream of driving fluid under pressure can thus be subdivided and distributed among theinlets 87′, 87″, . . . so as to gradually increase the volumetric ratio between the volume fed of mercerizing solution and the amount of thread operating in the axial direction, from the beginning to the end of the sequence. The bundle ofyarn 4 being processed, again deviated by adeviator roll 9, enters in an axial direction from thefirst Venturi 86′ and axially follows the whole sequence receiving, in correspondence with each narrowing and depression of the contracted vein of the fluid, the arrival of the partialized stream of driving fluid from theirentrances 87. Along the path of theyarn 4 there is consequently a considerable pulsation of contact conditions, such as rate and pressures of the fluid which flows around the bundle ofthreads 4. A second further embodiment variation of the invention contemplates, in correspondence with thefirst entrance 87 for the process fluid, anentrance 88 for service connection with compressed air, both for maintenance operations and for the activation of the reaction unit with the insertion of thebundle 4 in the sequence ofVenturi tubes 86. - This embodiment variation of the reactor85 with
several Venturi nozzles 86 in series allows a more effective contact and sealing for the fluids and can be adopted both for mercerizing reactors and for the subsequent washing and neutralization operations of theyarn 4 after the treatment with alkaline solutions. - The enlarged detail of FIG. 2 shows an illustrative structure of the
compensator 25, with which the tension of the bundle ofthreads 4 rising towards the drawing system, is regulated and controlled. The compensator comprises two end pulleys 91, 91′ situated at the ends of atelescopic rod 92 whose extremes are maintained in extension by aninternal spring 93 set under compression. The higher tension of the bundle ofthreads 4 tends to draw the end pulleys 91, 91′ closer and compress thespring 93. Thetelescopic rod 92, for example, has the lower end fixed to the structure and the upper end free to be extended: thepulley 91 is therefore free to move away from thepulley 91′, which remains still. Tworeference points telescopic rod 92, which represent fixed and adjustable limits of the approaching and distancing run end, respectively, of the two pulleys, detected by twoproximity sensors - When the
sensor 95 detects that thereference point 94 has reached the set approaching limit, or compression limit of the telescopic rod, the tension increases to the maximum value allowed and the driving unit of the treatment device operates an increase in the feeding rate of thethread bundle 4. When, on the contrary, thesensor 95′ detects that thereference point 94′ has reached the allowed extension limit of the telescopic rod and that the tension has been reduced to the minimum value allowed, the driving unit of the treatment device causes a decrease in the feeding rate of thethread bundle 4 until the telescopic rod has been extended to an intermediate value. When the extension of the telescopic rod remains within the set range, the driving unit of the device remains inactive in the regulation of the feeding rate of the bundle. - The process for the continuous treatment of yarns with process fluids, according to the present invention, and, in particular, the mercerizing process described above, allows remarkable advantages to be obtained with respect to the processes of the known art. Mention should be made in particular to the following characteristics.
- According to the present invention, the treatment operations with process fluids are effected with continuous operations, and not on lots of yarn, without requiring previous preparation on bobbins or skeins followed by their unwinding and re-preparation.
- According to the present invention, continuous yarn processing is more economical, due to the lesser amount of labour used, the high performance of the process fluids and washing water, the lower overall plant investments and, finally, fewer environmental implications as a result of the reduced quantity of reagents discharged with the waste water. The constancy of the product quality which is obtained with the continuous treatment system according to the present invention is considerably improved, due to the constancy of the parameters of each processing step which can be maintained at the desired temperature, time, concentration values. The amounts of treatment solutions are extremely limited and, as far as the mercerizing alkaline solutions are concerned, their carbonation is very moderate.
