The invention mainly relates to a process for the finishing of textiles to improve the quality of woven and knitted materials. More precisely, it concerns a process of hydraulic tangling, which increases woven and knitted materials through the use of dynamic liquid jets, specialsa threads of the fabric and leading to their Vysocany. Fabric created by the method according to the invention, have improved finished surface, increased durability and improved performance, such as potriveste air, the disappearance of wrinkles, absorption, adsorption, resistance to shrinkage, creep seams, wear to edges.

The quality of the woven or knitted material can be evaluated for various properties, such as the number of yarns, threads, resistance to abrasion, Kazatomprom, weight, volume yarn, Vysocany yarn, resistance to torsion, disappearance of wrinkles, use as draperies and handmade.

The number of yarns is a digital symbol, which indicates the size of the yarn and on the relationship of length to weight.

The number of threads in a fabric or knitted materials, respectively, determines the number of warp threads and weft threads, as well as scars and rows per inch of fabric. For example, the number of tissue is indicated by the first indication of the number of warp threads per inch, and then the number of filling weft threads per inch. So, the numbering 88 x 72 defines a fabric having 68 warp and 72 filling weft threads per inch.

Abrasion resistance is the ability of a fabric to resist the loss of appearance, practicality pile or surface in destructive action of surface wear or abrasion.

Absorption is the process of filling the solid particles to the surface of textile fibers, yarns, fabrics or any material.

Potriveste is the degree to which the underlying tissue structure is hidden by the surface material. Rating Kazatomprom is the air permeability of the fabric, i.e. the ease with which air passes through the fabric. Permeability allows to estimate the fundamental properties of fabrics and features like filtering and potriveste.

Vysvechivanie is an assessment of unfolding and distribution of fibers in the yarn.

The fabric weight is measured in weight per unit area, for example in ounces (28,3 g) per square yard (0,82 m2).

Torque tissue refers to the characteristic that makes it turn performed by itself as a result of twisting. It is desirable to eliminate or reduce the torque of the fabric. For example, the fabric used for vertical blinds, should not have torque because the torque causes the fabric to curl, when she hangs in the form of a strip.

The disappearance of the folds is a property of the fabric, which allows it to recover from orogenic deformation.

The durability of the surface of the fabric is the material resistance to the loss of the physical which I handmade refers to such properties of the textile fabric, as soft and used for draperies.

In the prior art there is information on the application processes the hydraulic entanglement nonwoven materials. In conventional processes tangling pieces of non-woven materials will remain the handling fluids under high pressure, when they are on the patterned screen with holes. Usually patterned screen runs on a drum or continuous flat conveyor, which stands in the way of jets of fluid under pressure to the tangling of the fabric in the bond order of the group of fibers with configurations corresponding to the open areas of the screen. Obfuscation is performed under the action of jets of fluid which cause the fibers in the fabric to move to open areas in the screen, when they tangle and intertwine.

Known processes hydraulic tangling in the production of patterned non-woven materials is presented in U.S. patent N 3485706 and 3498847, as well as in U.S. patent N 3873255 and 3917785.

Fabric processing is performed by a large number of passes with purpose, the hydraulic entanglement, in which the fabric is reoriented in the direction of the displacement with respect to the direction of the process, in order to perform uniform clutter. The data given in the examples, indicate a moderate tangling in the fabric surface and moderate stability.

Another approach in this sector is provided in European application N 0177277, class D 06 C 23/04, which refers to the technology Gidravlika speed, on woven, knitted, concatenated materials for producing decorative effects. Receiving pattern is accomplished by redistributing the tension of the threads in the fabric - yarn selectively compressed, loosen and open up, to give the fabric a relief structure.

In Fig. 1 shows the preferred implementation of the production line according to the invention, indicated by item 10, which is designed on uchet in normal device 14 to straighten otoceny, flat and drum amplifying modules 16, 18 and tentering frame 20.

The modules 16, 18 is provided at two lateral reinforcement fabric by liquid tangling and accumulation of threads of the fabric. Such obfuscation is given tissue in areas of intersection or weave. Management process and ensuring a uniform liquid curtains create a fabric having a uniform finished look and improved features, including wear, twist, loss of rugosity, vitiagivaet, use as draperies, stability, resistance to abrasion, weight and thickness of the fabric.

The fabric moves through the device 14 to straighten otoceny, which aligns the weft threads of the fabric before treatment in the amplifying modules 16, 18. After hydraulic strengthen the fabric is pushed to the tentering frame 20, which is of conventional design, where the fabric is dried under tension to create a homogeneous tissue of a certain width.

The module 16 includes a first supporting element 22, which is held on the endless conveyor comprising rollers 24 and drive means (not shown) for rotation of the rollers. Preferred linear speed of the conveyor is in the range of the, which varies as a function of the type and weight of fabric.

The supporting element 22, which preferably has a flat configuration, includes liskouskaia from each other permeable fluid open area 26. Preferred supporting element 22, shown in Fig. 2A is a flat woven mesh 36 x 29 90ohaving open area, part of 23.7%, made of polyester substrates and providing the sliding round wire. The support element 22 is a dense, seamless woven element, which is not subjected to angular displacement or striping. Characteristics of the screen, which is manufactured by the firm of Albany international, Appleton ways division, N. O. Box 1939, Appleton, Wi 54813, indicated in table I. the Module 16 also includes a device from a parallel and spaced from each other highways 30, oriented in the transverse direction (DM) relative to the moving fabric 12. Line, which are separated from each other by approximately 6 inches (20.32 cm), include a large number of carefully aligned and spaced apart holes 32 for columnar jets, which are approximately 0.5 inch (1.27 cm) from the support element 22.

Tests on the capacity of the leaching was carried out in accordance with the following process. Weight measurement (before washing) were performed on control and treated tissue samples, each of which had a size of 8.5" x 11"(21.6 x 28 cm) (8,5" in the direction of perform and 11" in the direction of the base). Then the samples for three consecutive operations were washed and dried in the usual washing and drying devices, and were made polypropylene measurements. The weight loss in percent before and after leaching the samples was determined according to the following formula:

% weight loss = D/B 100,

where B is the weight of the sample before washing;

Hydrosaline tissue causes vysvechivanie and tangling at the point of intersection with filling open areas for improving surface finish and reducing the permeability of the fabric of the air.

In Fig. 12 and 13 shows the micrograph fabric grade Hitex intended to cover the walls, which is manufactured by the firm Hitex, Inc., Randolph, Massachusetts. Giving multiple frame types the surface of the fabric is performed by threads that are interwoven through a separate zone of the front surface of the fabric. Free-floating stitches weaves, indicated in Fig. 12B and 13B by the letter S, formed on the reverse side of the fabric.

Hydrosaline fabric brand Hitex wall covering attached to the back side of the fabric freely floating stitches 5 increases the stability of the fabric and its potriveste (see Fig. 12B, 13B). When applying wall covering strengthening tissue and related effects of stabilization reduce or eliminate the need for adhesive rear is their adhesive through the fabric. Provides an added advantage when reinforced fabric used in acoustic purposes, the exception coating on the reverse side reduces reflections and provides additional sound transmission through the fabric. In Fig. 14A, IN the present macrophotography control and treated acrylic fabric for curtains made U. S., Libby and denoted S/406. The strengthening of the fabric reduces its torsion, which is especially beneficial when using fabric for curtains. When testing for the reduction of torsion according to Fig. 14 A, B are applied to the strip length 84" (2,12 m) and a width of 3.5"(0.08 m), which were vertically suspended without tension. Torsion was measured by the angle of torsion of the fabric from the flat support surface. As you can see in the pictures, the torsion of the 90oin untreated tissue, Fig. 14A, was excluded in the amplification process.

In Fig. 15 A-C presents macrophotography control and treated acrylic tissue type Libbey respectively, N 022, 406 and 162, which were tested for prominenet. Raw tissue showed significant wear and destruction of contrast enhanced tissue that shows limited wear and loss of yarn (weight). Table XI made the process of amplification according to the invention, designed to provide superior characteristics of finished textile, such as potriveste surface, resistance to deterioration, disappearance of wrinkles, tensile strength and air permeability. Additional distinctive features of the fabric, which can be obtained according to the invention include improving the durability of the fabric surface, absorption and adsorption, as well as reduced shrinkage. In addition, providing the advantage of characteristics of the tissue are obtained with amplification process according to the invention and specific materials. For example, it was found that amplification of woolen fabrics allows to obtain a dense and compact materials which are resistant to shrinkage. In the case of another application of the technology according to the invention obtained improved tissue in relation to its fire resistance when machining materials based on polyester.

The following examples illustrate additional applications and embodiments of the invention. As in the previous examples, the tissues were processed on a production line according to Fig. 1, described in the preceding examples. Fabrics were subjected to the process of hydraulic amplification under davleniya energy for specialsa modules were maintained at the level average of 30 ft/min and 0.5 HP h/lb. Adjust the speed of the production line and fluid pressure was carried out for adaptation to different weights of fabric to ensure uniform processing and preservation of preferred energy levels.

Example XIV

The durability of the fabric surface

At a known finishing processes to ensure the durability of the surface of the fabric used binder chemicals that hold the fibers in a stable orientation. Such bale processes to ensure the "durability" or "unchanged" stiffen the finished fabric and adversely affect such characteristics of the fabric, as its use as draperies and handmade. The process hydrostrengthening according to the invention makes the fabric increased durability of the surface without the need for chemical treatment. This result is achieved by stabilizing the matrix structures of the tissue in the process gain due to tangling of the threads. Amplification as a mechanism of retention of fibers according to conventional chemical processing.

In Fig. 16A, B - 18A, B, respectively, are presented macrophotography controlee, 2) woven fabrics of 100% polyester, includes woolen upholstery yarn, the number of threads is h/inch2and weighs about 8 oz/yd2and 3) tissue Guildford from 80% wool and 20% nylon (see table II).

Durability test was conducted by exposing the tissue samples five times washing treatment with washing and drying. Test conditions approximately corresponded home washing with warm water and drying with hot air, as defined in the Technical Manual EATS, Test Method 124 - 1984. The control and the treated fabric was placed on the Board and was highlighted at an acute angle by a fluorescent light source for microphotographing comparison. Raw tissue differed rough, mottled and knotted trim in comparison with reinforced fabric, which showed a smooth and compacted finish.

Example XV

Resistance to shrinkage

Fabric reinforced according to the invention, exhibit improved resistance to shrinkage. In tables XII-XIV summarizes the tests for shrinkage handling control and enhanced tissue by rinsing/drying and dry cleaning. The shrinkage of the fabric was measured by drawing on and the charge relative to the measuring lines. As in the previous example XIV, washing conditions in accordance with the standards specified in the Technical Manual EATS, the Method of testing 124-1984.

Comparing the test data of treated and control tissue indicates that the reinforcement according to the invention provides a measurable reduction in shrinkage. For example, after five cycles of washing/drying reinforced fabric consisting of 65% wool/poly (ethylene terephthalate), had a shrinkage of 6.9% compared to 14.4% of shrinkage of untreated control tissue.

You should pay attention to the table XIV shows the shrinkage of wool fabrics. You can see that stabilization of wool fabrics provides a "wash coat" without the need for conventional chemical finishing treatment.

Example XVI

Absorption and adsorption

Reinforced fabric according to the invention show improved properties in terms of absorption and adsorption. In table XV summarizes the water retention ASTM presents for fabrics treated in accordance with the invention.

Example XVII

Gidravlika wool

For finishing woolen or worsted fabrics are commonly used processes felting or valachian and pressure, what causes tangles and seal with obtaining a stable structure. Installed, and it provides benefits that comparable results are obtained according to the present invention without the need for conventional chemical and mechanical processing and related permissions tissue.

In tables XVI A-C shows the comparative data for conventional milled and hydraulically reinforced woolen fabrics, unbleached and undyed state. Control and processed in the usual manner tissues were obtained from Carleton Woolen mills, Winthrop, Maine. Control tissue in unbleached and undyed state, respectively, had the weight of the order of 180.5, to 252.7 and 145,9 g/yd2before applying hydraulic amplification and conventional felting. Data regarding hydraulic amplification is provided for processing each control line tissue with energy on the order of 0.5 and 1.0 HP h/lb. You can see that the fabric treated according to the invention have physical properties that are similar to properties of the tissue undergoing the usual felting.

Tests with hydraulic amplification ("hydraulic felting"), information on which is given in tables XVI A-C, was performed using the Pro-and the process of hydraulic felting can be obtained by using specialsa modules of hot water. For example, use in the production line of hot water will be further evolutivity and to confuse the wool fibres. To this end, in the invention it would also be advantageous to use the hot tub or stage skolachivaniya for pre-tangling.

Example XIX

Flammability

Fire in the case of the well-known tissue is usually achieved by chemical processing of materials based on fibers with a high melting point. For example, the polyester has a melting point in the range 480 - 500oF (249 - 260oC) and finds wide application in the manufacture of fire-resistant materials. Such polyester materials are usually subjected to degreasing to provide material that does not contain impurities, which, in turn, tightly covered with a chemical finish.

Found that polyester fabric treated according to the invention demonstrate increased resistance. In table XVII shows the data Flammability test samples of a flat polyester fabric, reinforced according to the invention. Sample No. 1 is to test the control and the previous processing enhanced fabrics, including five (5) test samples. Prevideo NFPA given in table XVIII. Reinforced fabric demonstrates the resistance, which exceeds the resistance of the tissues VISA and TREVIRA. It can be assumed that these results are a function of the degreasing process gain, and improved stability of the fabric due to tangling of the threads. Additional advantages according to the invention can be obtained by completing the finishing of the fabric to limit contact with treated cloth pollutants.

The following table from NFPA 701 indicates the permissible limits for these tissues.

In Fig. 19 shows an alternative implementation of the device according to the invention, indicated by the position 40. The device includes a large number of drums 42a-d, over which the fabric 44 moves when it is increased. More precisely, the fabric 44 passes the processing line in a sinusoidal path consistently below the reels and on top of them. For holding the fabric at opposite ends of the lines are made in the vicinity of the reels 42a and d rollers 46a and b. Each of these drums or all of them can rotate the respective drive motor (not shown) for advancing the fabric on the line.

A large number of nozzles 48 are made by groups is Kabanov 42a-d. When the location of groups of nozzles with an interval of 90oon the sinusoidal path of the fabric, these nozzles are sequentially installed at a distance relative to the opposite surfaces of the fabric. Each nozzle 48 provides a dynamic impact on the fabric of the columnar jets 59 liquid such as water. The device 52 for supplying a fluid delivers fluid to the nozzles 48, which in the course of treatment is collected in the tray 54 for recirculation through line 56 back to the pipes.

Supporting the reel 42 may be porous or non-porous. You can be sure that advantage is achieved through the use of drums, which include perforated support surface. Open areas in the support surface to facilitate the recirculation of the fluid used in the amplification process.

As previously indicated in the discussion of the first variant implementation, the additional advantage is obtained through the use of reference surfaces having the form of malosetti open areas, which facilitates the passage of fluid, the orientation of the support elements on the branch, such as branch at 45oas shown, limits the bandwidth when processing water, and the effect on the fabric. Preferred levels of energy for amplification according to the invention are in the range from 0.1 to 2.0 HP h/lb. Variables that determine the energy levels in the process include linear speed, the number and speed of the liquid, which has a dynamic effect on the fabric, and the weight and characteristics of the fabric.

The speed and pressure of the liquid is partly determined by the characteristics of holes for fluid, for example, columnar or fan-shaped configuration of the jet, as well as their location and distance from the processing line. An additional distinctive feature of the present invention is to effect a liquid curtain on the processing line for the dynamic effects on the fabric energy flow approximately 0,46 HP h/lb. The preferred characteristics of the type and location of the holes indicated in the description of option implementation according to Fig. 1. In short, the holes 16 are very close to each other, so that the distance between their centers approximately of 0.017 inch (0,043 cm), and their distance from the reference elements is 0.5 inch (1.27 cm). Holes with a diameter of 0.005 inch (0,012 cm) when their density, component 60 inch pipe, releasing a jet of results, obtained in the processing line shown in Fig.20.

The above examples illustrate the application of the process hydrostrengthening according to the invention for improving the quality and physical properties of single-layer fabrics and knitted materials.

An alternative application of the process of hydraulic amplification according to the invention the layers of tissue by means of hydraulic impacts are concatenated into a single composite fabric. In Fig. 20 shows the composite flannel fabric 60, which includes layers 62, 64. The hydraulic clutch of the first layers is carried out by giving the hairiness of the opposite surfaces 62a, 64a of each layer to lift the fiber surface. Then the opposite surfaces 62a, 64a are arranged with overlapping and processed on a processing line according to the invention, see Fig. 1 and 16. Strengthening layers 62, 64 leads to tangling of the fibers in fleecy surfaces and adhesion layers for formation of the composite fabric 60. The outer surfaces 62b, 64b also usilivayutsya surface 62a, 62b are provided through the use of conventional mechanical devices to make hairiness. Such a device includes cylinders covered with metal points or vorovannymi cones, which produce the Stripping surfaces of the fabric.

Composite fabric 60 mainly manufactured without the need for conventional adhesives for layers. In the composite fabric is ventilated and has an improved visual characteristics than the characteristics obtained in the case of a known laminated composites. It is clear that such composite fabrics have many uses in the industry, such as clothing and footwear.

Preferred results can also be obtained by means of hydraulic amplification of a single layer of napped fabrics. Tangles raised fleecy fibers in the fabric surface, made when carrying out the process according to the invention, allows the fabric with excellent finishing.

The composite material 70 includes a carded nonwoven and woven layers 72, 74, which RA. the hydraulic clutch layers and tangles carded nonwoven layer 72 are in the process single-stage liquid treatment. The strengthening of the associated composite to obtain a fabric having superior coating and finishing. Such non-woven-woven composite materials, along with other instances, they are used as spacers in the textiles.

In another embodiment of the invention are knitted or woven materials that contain wrapping twisted yarn having a core of fibrous strands and water-soluble components of the outer shell. The hardening process provides the leaching of soluble shell and tangles of fibrous material of the strands of the core, in order to obtain a stable material. Brown spun yarn, making the fabric structural integrity, useful to facilitate weaving in obtaining a stable material for reinforcing treatment. The strengthening of the fabric and rinse wrapping yarn allow you to get a fine fabric with superior structural integrity. In the case of the preferred application of the threads of the fabric include the core of the cotton fiber strands having filamentary wrapper from the ptx2">

Optimal amplification (in single-layer or multi-layer fabrics) is a function of energy. Preferred results are obtained when the energy levels, constituting approximately 0,5 HP h/lb. Energy requirements, of course, will vary for different tissues depending on the process conditions needed to achieve optimal energy levels. Generally speaking, to obtain the preferred energy levels can be changed the process speed, the configuration of the nozzles and the distance between them.

Reinforced fabric according to the invention preferably are made from a yarn comprising fibers having denier and length, are in the ranges respectively from 0.3 to 10 and from 0.5 to 6.0 inches (1.27mm - 15,23 cm), and the number of yarn from 0.5 S before the 80S. The optimal gain is achieved in the tissue having a denier fibers in the range from 0.5 to 6, staple fiber from 0.5 to 6.0 inches (1.27mm-16,24 cm) and number of yarns in the range from 0.5 S to 50S. The preferred system spinning applicable in the case of fabrics according to the invention include cotton woven yarn, wrapping twisted yarn and woven wool yarn. Experiments show that the preferred labo twisted yarn.

So far in this industry have not been identified advantages of hydraulic amplification, and the degree to which it may be applied hydrosaline to improve the quality of the fabric. It should be emphasized that the results achieved in the invention represent a significant and unexpected contribution to the industry. In light of the above content possible number of modifications. For example, although in the case of the preferred process and apparatus are used permeable supporting elements, the scope of the invention include non-porous support elements. Similarly, Fig. 1 and 20 respectively illustrate the production line process with two and four stages of amplification. System, which can be used in the invention include one or more modules with flat, drum or other supporting element.

It can be understood that the process according to the invention can be widely applied to production of a great diversity of reinforced fabrics. Therefore, the examples are not prednosti jets and create a liquid veil used holes for this purpose, can be applied to other devices. Attention should be paid to the U.S. patent N 4995151, "Method and device for hydraulic application of the pattern on the fabric, which discloses a device for tangling diverging jets of fluid used in hydraulic obtaining pattern on woven and nonwoven textile materials.
