Fabric and method for manufacturing the same

FIELD: textile industry, in particular, structure of fabric and method for producing such a fabric.

SUBSTANCE: fabric is manufactured by interweaving of warp and weft threads, with weft threads being combined thread including polyurethane core making 0.5-5.0% by weight of fabric, and twisted layer. Fabric is composed of thermally stabilized filaments. Warp threads and twisted layer are made from cotton filaments. Surface density of fabric is 75-435 g/m2, with number of warp threads per 10 cm making 154-446 and number of weft threads making 150-481. Method involves providing mutual interweaving of weft and warp thread systems; performing chemical processing, dyeing, printing and providing final finishing. Thermal stabilization process is carried out at temperature of 170-1900C for 40-90 s immediately before preliminary chemical processing or dyeing or printing process or before final finishing procedure.

Data the invention relates to the textile industry, and more specifically to the design of elastic fabric and method of its receipt.

Known fabric made by interweaving main and weft threads, the latter of which represent a composite thread comprising a polyurethane core with an attachment in the amount of 0.5 to 5.0% by weight of the fabric and okrutny layer, RF patent 2124598, 1997

The disadvantage of this solution is the lack of dimensional stability of the fabric during operation. In the operation of the fabric, having a high elasticity, gradually shrinks, reducing the original size. This leads, for example in clothing, to irreversible changes, which do not allow to use a specific user for the initial appointment. Another disadvantage is the use of fibers that due to hygienic features alien to the human body (artificial and/or synthetic). In addition, these tissues are complex (mixed) and use fiber (wool, linen, silk), which are produced in the world in limited quantities, and roads.

The technical result of the proposed solution is to create a range of elastic tissue with a stable size, using fibers, hygienically convenient for the person and more de is of evah.

This technical result is achieved due to the fact that the fabric made by interweaving main and weft threads, the latter of which represent a composite thread comprising a polyurethane core with an attachment in the amount of 0.5 to 5.0% by weight of the fabric and okrutny layer consists of a thermally stabilized fibers, and the main thread and okrutny layer is made of cotton fibers, and the surface density of the fabric is equal to 75-435 g/sq. m for the number of threads per 10 cm, equal 154-446, and duck 150-481.

This goal is achieved because the fabric is made of twill, plain or satin weave.

A method of obtaining normal tissue, which consists in the mutual interlacing of warp and filling systems the main thread, preliminary chemical processing, dyeing, final finishing. Figado, Mvician, Auimatagi “Chemical technology of fibrous materials”, 1968, M: Publishing house “Light industry”, p.3.

The disadvantage of this method is the inability to get a ready-made elastic fabric with stable dimensions during operation.

The technical result of the method is to obtain elastic fabric with a stable operational dimensions.

This technical result according to the first embodiment is achieved in that in the method is Holocene fabric, which consists in mutual interlacing of warp and filling systems the main thread, preliminary chemical treatment, dyeing, printing, final finishing, the fabric is subjected to thermal stabilization at a temperature of 170-190°within 40-90 with immediately prior to chemical pretreatment.

The second option is specified technical result is also achieved by the fact that in the method of obtaining tissue, which consists in the mutual interlacing of warp and filling systems the main thread, preliminary chemical treatment, dyeing, printing, final finishing, the fabric is subjected to thermal stabilization at a temperature of 170-190°within 40-90 with directly before dyeing.

In the third version of this technical result is achieved because the method of obtaining tissue, which consists in the mutual interlacing of warp and filling systems the main thread, preliminary chemical treatment, dyeing, printing, final finishing, the fabric is subjected to thermal stabilization at a temperature of 170-190°within 40-90 with just before printing.

According to the fourth variant of the same technical result is achieved in that in the method of obtaining tissue, which consists in the mutual interlacing of warp and filling systems the main thread, preliminary chemical treatment, dyeing, printing, Z. the final finish, the fabric is subjected to thermal stabilization at a temperature of 170-190°within 40-90 with directly before the final finish.

These distinctive features of the variants have been identified in other technical solutions in the study of this and related areas and do not follow explicitly from the prior art that is new and corresponds to inventive step.

Hereinafter the invention will be shown by the examples in the table.

Fabric form twill, plain or satin weave on a loom STB-220. The main thread uses only cotton fiber. As the weft threads are combined threads, which contain a core of polyurethane thread, obruchennye only cotton or yarn. Attachment polyurethane yarn in the fabric is 0.5 to 5%, and the surface density of the fabric is equal to 75-435 g/sq. m for the number of threads per 10 cm, equal 154-446, and duck 150-481. After receiving harsh fabric it is subjected to chemical processing equipment for finishing fabric width at temperatures and chemicals, carefully affecting fragile polyurethane thread. At different stages of processing (pre-treatment or dyeing, or printing, or the final finish) the fabric is treated paracingulum with a temperature of 170-190° With over 40-90 on drying and tentering frame “Elitex”.

As shown in the table examples show that when using the significant distinguishing features specified in the claims can be obtained tissue from the lung of dress up heavy clothing destination with a stable geometrical dimensions, continued for a long time.

Indicators on the shrinkage and elongation of the prototype is much worse than any of the variants of the inventive fabric, which confirms the industrial feasibility of the method. Options tissues with parameters outside the limits specified in the table of ranges of surface density, density of the warp and weft threads and attachments in the fabric polyurethane yarn, obtained at the tabulated ranges of temperature and time of thermal stabilization, give unusable results.

Fabric made by interweaving main and weft threads, the latter of which represent a composite thread comprising a polyurethane core with an attachment in the amount of 0.5 to 5.0% by weight of the Kani and okrutny layer, characterized in that it consists of thermally stabilized fibers, and the main thread and okrutny layer is made of cotton fibers, and the surface density of the fabric is equal to 75-435 g/m2when the number of threads per 10 cm, equal 154-446, and duck 150-481.

2. The fabric according to claim 1, characterized in that the twill, plain or satin weave.

3. A method of obtaining a tissue, which consists in the mutual interlacing of warp and filling systems the main thread, preliminary chemical treatment, dyeing, printing, final finishing, characterized in that the fabric according to claim 1 is subjected to thermal stabilization at a temperature of 170-190°within 40-90 with immediately prior to chemical pretreatment, or dyeing, or printing, or before the final finish.
