摘 要
本文通过先制备醋酸乙烯,聚乙烯醇为原料,制备聚乙烯醇纤维。醋酸乙烯是通过乙烯法和乙炔法制得的
,经过紫外线、γ射线、X射线等作用聚合;聚乙烯醇通过高碱醇解法,低碱醇解法制的。聚乙烯醇纤维经过制
备纺丝原液,纺丝成形,后加工制的;纺丝原液的制备需要先水洗并脱水,溶解,混合,过滤和脱泡;接着使
用湿法和干法纺丝成形;然后进行拉伸,热处理,缩醛化后加工,制的聚乙烯醇纤维。然后,分别介绍了水溶
性和高强度聚乙烯醇纤维的制备原理;水溶性纤维的几种纺丝方法,如湿法,干法,干湿法,半熔融,硼酸凝
胶,冻胶法,以及它的生产应用;高强度纤维的制备及应用和发展前景。

ABSTRACT
This text passes to make acetic acid ethylene first and gathers the ethylene Chun as raw material, the making gathers an ethylene Chun fiber.Acetic acid ethylene is get through ethylene method and B Gui legal system, after ultraviolet ray, the γ shoot line and X to shoot functions like line,etc to come together;Gather ethylene Chun to pass the solution method of Gao Jian Chun, the low alkali Chun solves jural.Gather ethylene Chun's fiber to spin silk threads an original liquid after making, spin silk threads to take shape and process something to make behind;The making that spins silk threads an original liquid needs first water to wash and dehydrate, fuse, mixture, percolation and take off a bubble;Immediately after use wet method and stem method to spin silk threads to take shape;Then carry on pulling to stretch, hot processing, shrink Quan to process after turning, make of gather an ethylene Chun fiber.Then, introduced high strength to gather the making principle of the fiber of ethylene Chun respectively;A few kinds of water-soluble fiber spin silk threads a method, like wet method, stem method, do a wet method, half meltdown, boric acid gel, the jelly gum method, and its production application;The making and application and development prospect of the high strength fiber.
