FIELD: textiles, paper.
SUBSTANCE: method of production of nonwoven fabric from fibre comprises the following steps: a) the step of production of fibres having a crystallisation temperature not exceeding 112°C, when the polymer is melted, which comprises polyphenylene sulfide as a main component which is substantially not copolymerised with trichlorobenzene, and the fibre yarns discharged from the spinning nozzles, are elongated and stretched at a spinning speed of at least 5000 m/min and less than 6000 m/min, using the ejector, which is located so that the distance between the lower wall of the nozzles and the hole for compressed air discharge of the ejector is from 450 to 650 mm; b) a step in which the resulting fibres are collected on a moving screen to form a nonwoven fabric; and c) a step in which the thermocompression bonding of the resulting nonwoven fabric is carried out by means of the hot drum.
EFFECT: exclusion of uneven shrinkage in width, surface roughness in preparation of nonwoven fabric from fibres containing polyphenylene sulfide as a main component.
