SUBSTANCE: invention relates to the textile industry, and refers to nylon staple fibres suitable for use in abrasion-resistant high strength nylon yarns. Obtaining of high strength nylon staple fibres with a denier per filament of about from 1.0 to 3.0 is included, as well as the strength of fibre T of at least about 6.0, and the carrying capacity T7 greater than about 2.5, including more than 3.2. These nylon staple fibres are manufactured by obtaining tows of filament yarns of nylon with a relatively high molecular weight (RV from 65 to 100), stretching and annealing of such tows using the two-stage stretching operation with annealing and subsequent stapling or other transformation of the tows stretched with annealing in the required high strength nylon staple fibres. The nylon staple fibres thus obtained may be mixed with the accompanying fibres such as cotton staple fibres, for production of nylon/cotton yarns (NYCO).

EFFECT: invention provides creation of nylon staple fibres for production of NYCO-materials which are abrasion resistant and have long service life.

SUBSTANCE: two-layer reinforcing fabric for elastomeric coating is proposed, made with a two-layer double weaving of warp and weft yarns and formed by junction together of the layers by two weft yarns, transferring from layer to layer. In each complete weave rapport the connecting weft yarns are located in cooperating pairs, which being opposite to each other alternately from above downwards and from below upwards encircle the extreme warp yarns of the rapport of each background layer, grouping the warp yarns into bunches forming on both sides of the fabric the identical bulged embossed longitudinal stripes spaced from each other. The pitch of the longitudinal strips is determined by the equation: t=50Rw/Pw and their number per 10 cm of fabric width is equal to n=2Pw/Rw, where t is the pitch of the longitudinal strips, mm; n is the number of strips per 10 cm; Rw is complete fabric rapport on the warp, equal to 6 or 8; Pw is the number of warp yarns per 10 cm. The proposed two-layer reinforcing fabric is made on the shuttle, gripper shuttle looms or rapier weaving machines. For production of reinforcing fabric with higher rates of breaking load on the warp each warp yarn in 6 or 8-yarn weave rapport should be repeated 2 to 4 times. To increase the breaking load of the fabric on the weft to 60% of the breaking load of the warp yarns, between the background layers alternately with the connecting yarns two filling weft yarns are additionally located, each of which being laid between the layers, forms with the extreme warp yarns the virtual elements of the plain weave, located obliquely to the surface of the fabric in the form of the break catenary curve.

EFFECT: increase of reliability, durability.

Said threads are transferred from one layer to another, and each of warp and weft threads forms two elongated double-thread overlaps and two short single-thread overlaps in weaving repeat pattern. Diagonal sections of weaving repeat pattern define four triangular fragments, each of which, when turned through 180 deg, coincide with pattern of respective symmetrical non-turned fragment. Biaxiisotropic fabric of such structure has resistance coefficient of at least 0.9 and relatively low flexural rigidity (not in the excess of 5/0 gf/cm).
