Description

 The invention relates to the textile industry, in particular to linen textiles, and for clean linen for various purposes, namely shirts, blouses, linen for table, bedding and underwear, for medical and sanitary purposes.

 Currently, work is underway on the effective use of natural domestic textile raw materials and their processing into a competitive range of products, in particular into plain fabrics, on the basis of progressive science-intensive technological processes.

 Flax is the only domestic cellulose-containing textile raw material. An urgent problem today is increasing the share of flax fiber for the production of environmentally friendly household fabrics and for fundamentally new medical products.

 Flax is a beauty, freshness, purity, health, unique hygienic and consumer properties of linen textiles are known.

 The flax industry produces a wide range of half-linen and linen-blend fabrics. The volume of production of pure linen fabrics is small, but even their properties do not fully comply with the requirements for competitive environmentally friendly linen fabrics.

 Domestic fabrics are characterized by increased material consumption and surface density of one square meter with a lower level of surface filling of the fabric; have an unsatisfactory final finish, as a result of which they have increased stiffness and creasing, low ductility and drape. For these reasons, pure-cloths produced at Russian enterprises have low competitiveness and are exported mainly in a harsh manner.

 Currently, almost all medical supplies are produced on imported fibers into Russia (cotton, synthetic fibers), and low-grade ones that do not meet medical and technical requirements.

 To improve operational properties, linen fabrics are additionally subjected to special treatments with functional additives. These are dressings, antimicrobial, antiseptic and other impregnations (Handbook of the chemical technology of processing linen fabrics. M., 1973, S. 162-182). However, the processing technology of linen fabrics is quite complicated and expensive due to the use of special preparations.

 The applied preparations remain on the material.

 An urgent problem is the design of environmentally friendly clean high-hygienic fabrics with improved biomedical properties.

 The modern market requires the development of clean fabrics with reduced surface density and material consumption. For the manufacture of a wide range of underwear, including dining room (tablecloths, napkins), bedding (sheets, pillowcases, duvet covers), personal (towels), underwear (nightdresses), children's and medical (corsets, bandages, graces, dressings materials, napkins, etc.), along with a mass of fabrics, compliance with GOST requirements is required in terms of physical and mechanical properties: tensile strength and tensile elongation, resistance to abrasion and tearing, surface filling of the fabric.

 For fabrics of shirts, blouses and clothing groups, their aesthetic design is of great importance. The appearance of the fabric should be elegant, if necessary, have a discreet pattern (carriage or jacquard) pattern.

 Closest to the technical nature of the claimed invention is a clean cloth for bedding and underwear. The fabric is produced with plain weave (GOST 10138-93 Fabrics, plain, linen and half linen, official publication Moscow).

 The specified fabric does not have a set of properties that satisfy modern consumers, and has a narrow range of use.

 An object of the invention is the creation of a fabric that ensures the achievement of a technical result, which consists in obtaining thin environmentally friendly high-quality fabrics with low material consumption, with improved consumer, hygroscopic and microbiological properties, and in expanding the assortment of non-woven fabrics.

 This technical result is achieved by a known fabric made by weaving warp and weft yarns, each of which contains ring yarn of chemically enriched linen fiber, and according to the invention, the yarn is a yarn of linen fiber, enriched without chlorine-containing oxidizing agents, with a linear density of more than or equal to 28.0 tex, with a ratio of linear filling of the fabric on the base and on the weft is 1: (0.35-1), moreover, flax fiber is a low-dimensional shredded fiber.

 Changing the values of the claimed distinctive features leads to a deterioration in the set of operational properties of tissues.

 Refined flax fiber and fabrics from these fibers are produced using environmentally friendly technologies. Use the yarn of the ring spinning method from pure fiber, for example, low-dimensional trefoil fiber N 12, which is ennobled without chlorine-containing oxidizing agents. The main and weft threads in the proposed fabric contain bleached yarn.

 The Eco fabric is produced on the STB machine, 60-200 cm wide. Specific examples of the proposed Eco fabric and the physicomechanical and microbiological properties are given in the table.

 The proposed structure of environmentally friendly fabric is rational, as the fabric has increased wear resistance due to high abrasion resistance up to 14 thousand and more, instead of 6 thousand according to the prototype, high hygienic properties due to increased water absorption up to 60% and higher, increased air permeability and practically do not contribute to the development of bacteria.

 Due to the physical characteristics of the fabric, they have a long service life, are resistant to washing and sterilization.

The proposed "Eco" fabric contains in the base and weft linen yarn with a reduced linear density, characterized by a reduced surface density of one square meter of 150-215 g / m ² with increased surface filling. The fabrics of the proposed structure are less dirty and better sterilized.

 The proposed "Eco" fabric has a set of hygienic and operational properties, which allows you to expand the unconventional range of highly hygienic fabrics for bedding, table, personal, underwear, medical (with improved medical and biological properties) linen, the fabric is widely used for the market of clothing fabrics, a new an artistic image of clean linen for summer clothes with high consumer and hygienic properties and reduced material consumption.

 The multifunctional value of Eco fabric leads to the need to increase textile production.

 The proposed "Eco" fabric made of linen fibers is environmentally friendly, has improved hygienic properties, and chemicals that could cause irritation of the skin were not used for chemical refinement of linen fibers.

 The Eco fabric has a high utility for humans, the negative consequences caused by microorganisms that appear when wearing clothes, underwear on the human body are eliminated, it ensures safety and comfort in extreme operating conditions.

 Eco fabric can be produced in a harsh, boiled, bleached, one-colored form and with a printed pattern.

Claims (2)
