(57) Abstract:

Agrituristica double-sided fabric relates to the textile industry and can be used for making clothes that protect from agreeporosity for aviabiletov racing, metallurgists, welders, firefighters. The fabric made a half - or double-layered weave of non-flammable and combustible component selected from the group of wool, cotton, flax fibers. Non-combustible component is a woven fire protective yarn of wool fibers, containing 1-10% of porcelanato potassium from the weight of the yarn. Combustible component is made in the form of a twisted yarn of wool, or cotton, or linen, or lgnomecanvas fiber. The ratio of fiber non-flammable and combustible component in the tissue is equal to, respectively, (2,2-4):1. The surface density is in the limit 210-650 g/m2. The fabric has high performance due to the increase of hygroscopicity and reduce the electrified. 2 C.p. f-crystals, 2 ill., table 1.

The invention relates to the textile industry and fabrics for special purposes, which can be used for the manufacture of clothing to protect them from agneepath the first fabric, consisting of a heat-resistant core and heteroclinic weft threads, surface filling of the outer layer of heat-resistant warp is 70-80% (author's certificate. THE USSR 1291624, D 03 D 15/08, 1987). The disadvantages of the known heat-resistant fabrics are its low hygienic properties, as well as the fact that it doesn't withstand exposure to open flame.

Known heat-resistant material with increased strength and heat resistant properties made from painted polyaramid threads corrugated loom and wool fibers in the ratio of 81-88% and 19-12%, respectively, and the coefficient of filling material is at least 50% on the basis of and 35,0% duck (Patent RU 2093622, D 03 D 15/12, 1997).

Known fabric for protective clothing for welders made plain weaves and contains the basis of cotton thread and fine woven linen weft threads with respect to the cross-sectional area of the main threads to the square of single pores between the interwoven threads equal to within 1.3 to 2.5.

However, the known materials on the operational properties do not satisfy the consumer (Author's certificate. THE USSR 1367569, D 03 D 15/12, 1985).

The closest analogue to this technama side of which is made mainly out of filaments of heat-resistant material, and wrong - with preferential access yarns from natural material, and a fabric made of satin, or twill, or plain or satin weave, and the output of filaments of heat-resistant material on the front side is 60-85%. As the heat-resistant material selected from a group of aramid, teligen, Lola, SVM, and as a natural material selected from a group of wool, cotton, linen, silk. The fabric is made of one-, half - or double-layer (RU 2016927, C1, D 03 D 1/00; 15/00; 11/00, 30.07.94).

However, the range is known tissue is limited, the structure of the tissue properties do not meet the modern consumer market.

The objective of the invention is the creation of igniteboston double-sided fabric that ensures the achievement of the technical result consists in expanding the range of ogneupoenykh bilateral tissues with high performance by increasing the hygroscopicity and reduce electrified.

This technical result in igniteboston double-sided fabric, made a half - or double-layered weave of non-flammable and combustible component selected from the group of wool, cotton, linen ate fiber, containing 1-10% of porcelanato potassium from the weight of the yarn, and a combustible component is made in the form of a twisted yarn of wool, or cotton, or linen, or lgnomecanvas fiber, contains, wt%:

Flax fibre - 30 - 40

Cotton fiber - 60 - 70

or

Flax fiber is 25 - 40

Viscose high-modulus fiber - 25 - 35

Polyester fiber is 30 - 50

the ratio of non-combustible fibers component and fibers of the combustible component in the tissue is equal to, respectively, (2,2-4):1, the surface density is within 210-650 g/m2and non-combustible component in the basis and/or in a duck further comprises a twisted yarn of polyaramid threads or polyoxadiazole fibers, and fabric made gladkokrashennoy or with a printed pattern.

The claimed combination of features allows you to create a new agrituristico double-sided fabric with the stated properties and go beyond the proposed limits and the use of other structures do not provide a technical result.

As flax fiber used, for example, modified linen fiber.

As the polyester fibers used, for example, Mylar fiber.

In ka is used, for example, Arselon or oksanalove fiber.

Offer agrituristico double-sided fabric to produce all types of weaving machines, for example on the loom STB-2-220, a complex weave. When designing fabric use the following transitions weaving: warping, preberanie or prikazovanje, weaving, and finishing production.

Picture weave and probanka in remise allow you to create on the loom bilateral structure using the basis and duck non-flammable and combustible components.

The colours stated igniteboston bilateral allows the fabric to give the fabric a textured effect.

The basis and duck when using yarns of different colors to get the fabric to the effect of "sandwich".

The offered fabric is made half - and double-layer weave of non-flammable and combustible components. As a non-flammable component used fire-protected painted or severe spun yarn of wool fibers, such as yarn linear density h Tex, colored active dyes and processed by porcelanato potassium in the presence of oxalic and hydrochloric acids.

For gaining ruego component in the warp or in the weft used spun yarn of wool fibers, for example, linear density h Tex, cotton, or linen fibers, for example, linear density h Tex or lesmana yarn, containing, wt.%: flax fiber 30-40, cotton fiber 60-70 or linen fiber 25-40, high modulus viscose fiber 25-35, polyester fiber 35-50, for example, linear density h Tex.

Non-combustible component in the basis and/or in a duck further comprises dyed with dispersed dyes or harsh yarn from fiber Nomex, for example, with a linear density of h Tex, as well as painted or severe yarn of Arselon or oksanalove fiber, for example, linear density h Tex. The fabric is made gladkokrashennoy or with a printed pattern.

The density of yarns per 10 cm in the warp is 210-620, duck 110-560, the surface density of the fabric is equal to 210-650 g/m2. The fabric is available in widths 140-160 see

The fundamental structure of the fabric shown in Fig.1 and 2 (Fig.1 - polutoraspalnaya fabric, Fig.2 - layer fabric).

In Fig. 1 shows the interweaving igniteboston bilateral polutoraspalnoy tissue, where 1 is the non-combustible component bases, 2 - fuel component of base, 3 - non-flammable component duck: a - cross section of tissue; b - PU fabric, where 1 and 2 - non-combustible component basis, 3 - non-flammable component duck, 4 - combustible component duck: a - cross section of tissue; b - longitudinal section of the fabric.

Specific examples of technological and physico-mechanical characteristics of the tissue shown in the table.

In examples 1 and 4 used fire-protected spun yarn of wool fibers, containing 1% porcelanato potassium.

In examples 2 and 6 used fire-protected spun yarn of wool fibers, containing 5% porcelanato potassium.

In examples 5 and 9 used fire-protected spun yarn of wool fibers, containing 10% porcelanato potassium.

In examples 12, 18, 21 and 15 used fire-protected spun yarn of wool fibers, containing 3% of porcelanato potassium.

In the examples 3, 7, 8, 10, 11, 13, 14, 16, 17, 19 and 20 used fire-protected spun yarn of wool fibers, containing 7% of porcelanato potassium.

Example 2 spun yarn from lgnomecanvas fiber contains, wt%: linseed modified fiber 30; cotton fiber 70.

Example 6 twisted yarn of lgnomecanvas fiber contains, wt%: linseed modified fiber 40; lapilloune fiber 25; viscose high modulus fiber 25; polyester fiber 50.

In example 12 spun yarn from lgnomecanvas fiber contains, wt%: linseed modified fiber 40; high modulus viscose fiber 30; polyester fiber 30.

In example 14 spun yarn from lgnomecanvas fiber contains, wt%: linseed modified fiber 33; viscose high modulus fiber 37; polyester fiber 30.

As can be seen from the table, declared tissue hygroscopicity increases to 11.4 instead of 7.4-7.8 for the well-known fabric, the fabric is almost not electrified, while the electrified known fabric equal 2,01011while she keeps the rest of the indicators at the level of: the fabric has a low shrinkage after wet processing, high abrasion. The value of the passing pulse when exposed to intense heat flux is 0.8-1.5 cal/cm2at the rate of 1.8 cal/cm2the fabric is not ignited, which ensures the protection of people from fire. Products made of this fabric is pleasant and comfortable to wear, because on the surface the inside out mainly natural fibers, which give high hygiene, physiological comfort due to certain usloviiakh colors allows you to extend the range of fabrics for clothing with attractive artistic kolloristike.

Replacement synthetic fire-resistant fire-protected fibers wool fibers dramatically reduces the cost declared tissues, and thus, much cheaper manufactured clothing, and what is also very important: it is made from domestic raw materials.
