Abstract

Inventia se refera la un procedeu de finisare a firelor poliacrilonitrilice, care, în scopul diversificarii gamei sortimentale, conferirii unui aspect deosebit, stabilitate dmensionala, reducerii consumurilor energetice de coloranti si produse auxiliare - consta în aceea ca firul având în compozitie pâna la 10% fibra poliacrilonitrilica color si 90 ... 100% fibra poliacrilonitrilica alba, rosiuni de 450 tor/m la filat si de 250 tor/m la rasucit se supune operatiei de contractare prin aburire la temperatura de timp de 96 ... 100 grade C, timp 25 ... 35 min, dupa care urmeaza operatia de avivare cu circa 1% produse catinice, timp de 25 ... 35 min, la temperatura mediului ambiant, iar apoi este tratat în conditii în sine cunoscute.The invention relates to a process for finishing polyacrylonitrile wires, which, in order to diversify the assortment range, to confer a special aspect, to reduce the energy consumption of dyes and auxiliary products, consists in that the fiber having up to 10% fiber polyacrylonitrile color and 90 ... 100% polyacrylonitrile white fiber, 450 torr / m high spinning and 250 torr / m twisted is subjected to steaming contraction at a temperature of 96 ... 100 ° C, time 25 ... 35 minutes, followed by about 1% catinic products for about 25 ... 35 minutes at ambient temperature and then treated under known conditions.
