    The invention relates to a technique for producing webs that can be used in the production of molded articles used in medicine and technology, in particular, to methods for producing textile webs.
    The purpose of the invention is to increase the stretchability of a textile web.
    The goal is achieved by preliminarily making a textile carrier from organic fibers and treating it with a water-curable plastic resin, using organic fibers with an elastic modulus of 200 to 2500 daN / mm in quantity, providing a weight of 40 to 300 g / m, moreover, prior to treatment with a water-curable plastic resin, the carrier
    subjected to thermal shrinkage and / or wet shrinkage.
    The treatment can be carried out by impregnation and / or coating.
    Thermal shrinkage is carried out either with air at a temperature of 80-250 ° C, or with water or superheated steam at a temperature of 100-80 seconds for 0.1- 60 minutes. Wet shrinkage is carried out by immersing and / or impregnating the carrier with a liquid medium, such as water, alcohol, if necessary in the presence of auxiliary agents, such as surfactants.
    After treatment with a plastic resin, hardened with water, textile fabric is stored for lack of moisture.

    The proposed textile fabric is distinguished by stretchability in both the riverine and longitudinal directions of the river.
    Longitudinal direction means the direction of textile processing, i.e. "; for example, by aligning the base or stitch columns
    The transverse direction means the direction, the vertical direction of processing of the canvas, Toe. the direction of the weft yarns or loops.
    The proposed textile web may have various geometric shapes, the preferred shape of the ribbon, or 1-1. How long is the side of the ribbon in accordance with the processing direction of the textile fabric The ribbon may be a fabric, knit, knitted fabric or canvas.
    Natural or chemical fibers can be used as organic fibers, and as natural fibers — in particular, vegetable fibers of seeds and fruits such as cotton fibers, bast fibers (hemp and jute) and hard fibers (sisal). Preferably use in particular cotton fibers.
    Synthetic polymers can be used as chemical fibers, for example, carbon chain fibers such as polyethylene, polypropylene, polychloride (for example, polyvinyl chloride and polyvinylidene chloride), polyacrylate and vinyl acetate fibers, hetero fibers, such as as polyamide, polyester and polyurea fibers, and polyaddition fibers obtained, such as spandex and elastano
    It is also possible to use viscose or elastodiene (rubber fibers.,
    Preferred synthetic fibers are polyester, polyamide, and polyacrylonitrile fibers.
    It is also possible to produce textile fabric from various fibers, preferably from polyester and / or polyamide and / or cotton fibers.
    textiles are preferred when using plant fibers

    Mixed yarn cloths, and in the longitudinal direction they use V9s from synthetic polymer, and in the transverse direction from vegetable fibers
    Preferably in the longitudinal direction, the yarn system provides, after the shrinking process, elastic stretching in the longitudinal direction. In the case of using natural fiber yarns, high twist yarns or twisted staple yarns with a twist factor of about 120 to 600 are preferred so that high twist is ensured high torque and, consequently, the tendency to form sucrutino The twist factor ". is determined by the equation

    in g / 1 000 m in order to avoid unwanted torsion of a textile fabric - the threads are preferably produced by a variable direction of torsion (clockwise S torsion, counterclockwise Z torsion), namely in an alternate order, for example, one thread S - one Z thread or two S threads - two Z threads.
    I
    As threads with long
    elasticity can be used as fibers from natural rubber (for example, from elastodiene), and fibers from polyurethane elastomeric fibers (for example, from elastane),
    To achieve longitudinal extensibility, complex textured yarns made of polyester, polyamide fibers and Todo are used as chemical fibers.
    The elastic properties of these complex yarns are based on the constant Twisting and torsion of the yarns achieved during the texturing process, which is ensured by the thermoplastic properties of the materials. It is possible to use all types of textured yarns, such as, for example, high stretch textured nnti, textured yarns with reduced stretch, high volume yarns.
    The yarn connection in the longitudinal system is provided with wrap yarns, and it is possible to use both staple or twisted yarns from natural fibers and staple or multifilament yarns (satin yarns) from chemical fibers. The strength characteristics of these yarns are used elastic modulus.
    Before curing with a plastic resin, the proposed textile fabric has a stretch in the longitudinal direction of 15-2007. By stretchability in the longitudinal direction is understood to be a change in length compared to a completely weakened textile cloth, which is achieved by loading the textile cloth in the longitudinal direction (10 N / 1 cm wide).
    Polymers based on polyurethane or polyvinyl resins are preferably used as water-curable plastic resins.
    The proposed web is preferably used for supporting dressings in medicine and veterinary medicine, they are distinguished by the comfort of application of the Toe. limbs of humans and animals without wrinkling can be found in difficult places, such as knees, elbows and felts.
