摘要
FIELD: textiles, paper.;SUBSTANCE: invention relates to the textile industry, and refers to nylon staple fibres with a high carrying capacity and mixed nylon yarns and materials made of them. The high strength nylon staple fibres are characterised by the denier per filament of 1.0 to 3.0, the strength of fibre T of at least about 6.0, and the carrying capacity T7 of more than 3.2. The tows of nylon filament yarns are manufactured, which are relatively uniformly moulded and hardened, by such tows stretching and annealing with the two-stage operation of stretching with annealing using relatively high degrees of stretching and subsequent stapling or other transformation of the stretched and annealed tows in the required high strength nylon staple fibres. The nylon staple fibres thus obtained may be mixed with other fibres such as cotton staple fibres, for production of nylon/cotton yarns (NYCO).;EFFECT: invention provides obtaining of fibres for production of materials with a long service life under conditions of increased wear.;27 cl, 4 tbl
