Description
(54) СПОСОБ.ОТДЕЛКИ ХИМИЧЕСКОГО ВОЛОКНА(54) CHEMICAL FIBER METHOD.
Изобретение относитс к производству химических волокон, а именно к способам их отделки.The invention relates to the production of chemical fibers, and in particular to methods for their finishing.
Известен способ отделки химического волокна, при котором осуществл ют термопластификацию, гофрирование и обработку волокна поверхност но-активными веществами (ПАВ) IJ .There is a known method of finishing chemical fibers, in which thermoplasticization, corrugation and fiber treatment with surface-active substances (surfactants) IJ are carried out.
Известный способ предусматривает последовательное проведение операций термопластификации и обработку волокна ПВА , что взаимно ухудшает технологический эффект от каждой операции в отдельности и. приводит к снижению качества отделки волокна и увеличению количества вещества, используемого дл обработки.The known method provides for the sequential operation of thermoplasticization and processing of PVA fiber, which mutually impairs the technological effect of each operation separately and. leads to a decrease in the quality of fiber finishing and an increase in the amount of the substance used for processing.
Целью изобретени вл етс повышение качества отделки и экономии материала.The aim of the invention is to improve the quality of finishes and save material.
. Указанна цель достигаетс тем, :что согласно способу отделки химического волокна, при котором осуществл ют термопластификацию, гофрирова-. ние и обработку волокна-ПАВ, последнюю осуществл ют одновременно с термопластификацией перед гофрированием , при этом термоплаотифйкацию и обработку волокна ПВА производ т. This goal is achieved by the fact that: according to the method of finishing a chemical fiber, in which thermoplasticization is carried out, corrugated. fiber and surfactant treatment, the latter is carried out simultaneously with thermoplasticization before corrugation, while thermoforming and processing of PVA fiber is carried out
паром, содержащим ПВА.в мелкодисперсном состо нии.steam containing PVA in fine condition.
Способ отделки химического волокна осуществл етс следующим образсм.The method of finishing a chemical fiber is carried out as follows.
В устройство дл диспергировани ПАВ ввод т концентрированное вещество и насыщенныйг пар под избыточным давлением. Выход щую из устройства турбулентную струю пара с распреде10 ленным в ней веществом направл ют на обрабатываемое- волокно, при эт.ом происходит конденсаци пара на холодном волокне с интенсивным нагревом последнего за счет выделени A concentrated substance and saturated vapor under pressure are introduced into the device for dispersing the surfactant. The turbulent vapor coming out of the device with the substance distributed in it is directed to the treated fiber, at which condensation of steam occurs on the cold fiber with intensive heating of the latter due to the release
15 большого количества тепла. При этом обеспечиваетс как равномерный нагрев волокна, так и равномерна его обработка ПАВ, а высока температура отделочного препарата (до ) 15 large amounts of heat. In this case, both uniform heating of the fiber and uniform treatment of the surfactant are provided, and the temperature of the finishing preparation is high (to)
20 способствует снижению в зкости и. улучшению адгезии его с волокном, что повышает качество волокна.20 helps to reduce viscosity and. improve its adhesion with fiber, which improves the quality of the fiber.
