Description

The invention relates to the production of textile materials, predominantly woven and in-hole spacing materials, operating under particularly difficult conditions and possessing increased wear resistance, low flammability, low pilling capacity, biostability, and used in shipbuilding, aviation industry, as well as for interior decoration of public premises, for workwear workers.

The decorative and finishing fabric developed from weft polyaramid yarns alternating with acetochlorinated weft yarns is known, and the main yarns are aromatic polyamide yarns. The fabric has abrasion resistance up to 25 thousand cycles, is characterized by high fire resistance, but is not resistant to mold fungi, which is especially important for materials used in humid atmospheric conditions. The fabric has a limited color gram, since the midi multifaceted yarn is produced straight / sharply, the fabric does not have comfort and is characterized by low hygienic properties, as it is made of synthetic polymers. The fabric is expensive, since the cost of a complex polyaramid yarn is 4 times higher than the cost of dyed polyaramide fiber phenylone.

Closest to the proposed one, is the sarosculoid lcd lret1 "Venus hnb-detachable fabric", which is used for upholstery of aircraft seats. In this fabric, weft and main threads are taken of the same raw material,%:

From the results given in table. one,

It can be seen that the proposed fabric is resistant to fire (when compared to h / w untreated furniture fabric), has a high durability, low peeling capacity, fabrics are resistant to the action of mold fungi, when compared with the known prototype.

Embedding in yarn fireproof wool, modified compound

5 zirconium / chlorendic acid in a mixture with heat-resistant polyaramide fiber in a ratio of (20-80) - (80-20)%, allows to obtain a surface density of less than 500 g / m2 material with high performance characteristics. When testing for flammability, it can be seen that replacing the acetochlorin fiber with a melting point of about 115 ° C in a known material with a heat-resistant phenic fiber eliminates the phenomenon of luminescence in the fabric, which actually is a continuation of burning. The introduction of full-ramide synthetic fiber with phenyl allows to obtain a fabric of enhanced wear resistance, namely, withstand abrasion up to 29 thousand cycles (with an investment of 20% wool).

The proposed fabrics are characterized by low pilling capacity, although it is known

5 that pure phenylone tissues are pilling, as well as tissues by the convergence of acetochlorinated fiber. The proposed fabric furniture fabrics have a good appearance, are especially aesthetic in the interior of the cabin

0 rooms of ships, aircraft.

Example 8 in the table. 1 shows that the modified b / w fabric is resistant to fire, i.e. self-extinguishing after removing ignition source, not

5 possesses the phenomenon of residual smoldering and luminescence, but is characterized by low resistance to abrasion, peeling capacity, and low tensile loads in comparison with the proposed fabrics. These properties of the material disappear when the wool is partially replaced with polyaramide synthetic fiber.

Fire retardant properties of wool can be given by dyeing its dye with mi5 flame retardants.

When dyeing wool fibers with chrome dyes, it can be seen that the concentration of potassium bichromate should be about 0.7–0.9% (by weight of wool fibers). At a lower concentration

The potassium dichromate fire-retardant properties of the produced tissue are significantly lower. The concentration of potassium dichromate above 0.9% is undesirable, as additional residual smoldering appears (glow of the ignited sample).

When using antipyrene dyes to modify wool fiber and dye it simultaneously, the concentration of dyes should be at least 4% (counting on a 100% pigment content).

With the resistance of the results obtained, it can be seen that the dyes-flame retardants, including chromic dyes, protecting the wool keratin from fire, produce a material with enhanced performance characteristics.

These methods of modifying wool fibers give almost the same fire retardant effect. The combination of phenylone modified in different ways and polyaramid fiber in a ratio of (20-80) - (80-20)% makes it possible to create fireproof fabric with increased wear resistance, low pilling ability and resistance to the action of mold fungi. The results table. 3 confirms the described positive effect obtained when using modified fire-protected wool and polyaramidic fiber phenylone in the material developed in the haly-straight way on a Malimo machine using 16.6 tex polyaramide complex yarn as a piercing yarn. The achieved fire retardant effect on the pierced-by-product is somewhat higher than on fabrics obtained on weaving looms, which is explained by the introduction of an additionally intersecting chain of polyaramid yarn stitching the weft and main p / yarns. The pilling capacity of the back-piercing fabric is low, since the stitched phenylone thread is on

seamy side of the canvas. A stitch length of 1.4 mm with a pile height of 3 mm ensures a low pilling capacity of the front side. And such characteristics of the material as breaking load, abrasion resistance, resistance to the action of mold fungi and flame are achieved due to the properties of the yarn used.

Thus, when analyzing the obtained results, it can be stated that the use of a semi-woven yarn made of modified fire-protected wool and polyamide synthetic fiber phenyl in a ratio of (20-80) - (80-20)% allows one to get woven or woven piercing material with significantly improved performance, namely fire resistance, abrasion resistance, low peeling resistance, resistance to the action of mold fungi.
