The invention relates to the textile industry and are encouraged to use when sewing a special technical service for employees of Ministry of emergency situations, Ministry of Defense, other law enforcement agencies, to protect workers with high temperature objects, excessive heat radiation, objects, molten metal, hot working shops and other

From the patent RU 2129173, IPC D03D 15/00, publ. 20.04.1999 known protective fabric having a fire-resistant impregnation, made on the basis of and the duck from the combined two-component yarn consisting of integrated aramid yarn twisted with cotton yarn.

As aramid yarn used filament-based polyparaphenyleneterephtalamide (terlan), polyparaphenyleneterephtalamide and their copolymers.

The disadvantage of this fabric is the absence of a flame-retardant properties without special impregnation and reduction flame retardant properties when washing, dry cleaning and in the process of operation.

From the patent RU №2216612, IPC 7 D02G 3/04, 3/36, D01D 15/10, 20.11.2003, known application of fibers based on aromatic polyamides polyparaphenyleneterephtalamide, polymethacrylamide, poliparafenilenvinilena comprising staple fiber yarn as a Supplement to the main component - the fluoropolymer fibers to create fabrics and molded product is (bearings, bushings, seals) with improved frictional properties. Supplements to the main component in the yarn can have a goal to compensate for the inherent fluoropolymer fiber disadvantages - low modulus, high shrink - to give additional strength or durability. The fabric according to this invention has good sound insulation, low friction properties, improved resistance to plastic deformation, however, does not have the fire, heat and thermal properties and can not be used for sewing special service fire, hot working shops, welders, metallurgists and others

From the patent RU 2258105, D03D 15/12 dated 10.08.2005 known technical fabric made of a yarn comprising staple fiber triple scented copolyamid or their mixture with natural or artificial, or synthetic fibers. The fabric is made simple weaves (canvas, twill, satin) or their derivatives and has a low resistance to burning. This indicator is at a temperature of 800°C is not higher than 1.5-3 seconds.

To fulfill the requirements of GOST 12.4.184-97 "Fabrics and materials for special clothing, tools, hand protection and upper shoes", this measure of resistance to the burning must be at least 30 seconds while maintaining the high strength characteristics./p>

The problem to which the invention is directed, is to create fabrics with a measure of resistance to proagainst not less than 30 seconds without special fire-retardant impregnation while maintaining a high strength at break and tear. Fabrics are made from staple core and weft yarn from a mixture of fiber-based triple scented copolyamid with natural or artificial fibers through derivatives, compound and complex weave weighing not less than 250 g/m2and resistance to burning up to 100 C.

As aromatic copolyamid used ternary copolymer of terephthalic acid dianhydride with diaminopyrimidines and paraphenylenediamine.

As the natural fibers can be used cotton, linen, wool fibers, as artificial fibers can be used viscose fibers.

Yarn in the proposed tissues has several advantages compared with the complex thread, it allows you to have a wide range of performance properties due to mixing with the main component of various staple artificial and natural fibers.

The yarn is increased in comparison with integrated filament elongation, elasticity and coefficient of friction. These properties POS is enable to produce fabrics with less rigidity, superior tailoring properties, drape and elevated ergonomic properties.
