聚对苯二甲酰对苯二胺及其共聚体纤维的成型新技术

聚对苯二甲酰对苯二胺纤维(芳纶1414)是经液晶溶液于喷—湿纺制得的高强、高模纤维，是当前最重要的高科技纤维。随着全球对芳纶需求量的增加及市场竞争的日益加剧，各国芳纶的生产厂家和研究单位都在不断地开发新工艺、新品种，以赋予聚对苯二甲酰对苯二胺纤维更优异的性能和尽可能地降低生产成本。本文综述了近年来芳纶生产的新工艺和具有各种特殊功能的新品种并简单介绍了该纤维的结构性能及发展方向。

Recent Progress on Fibers of Poly (p-phenylene terephthalamid) and its Copolymer

p Phenylene terephthalamid (PPTA) fiber is a kind of high tenacity and high modulus fiber, which is prouced by dry wet spinning through liquid crystal solution and is the most important high tech fiber currently. New technique and varieties of PPTA fiber have been developing by the factories and institutes of the same field to make it better properties and reduce the cost as low as possible with the increasing demand of PPTA fiber and market competition. In this paper, the new technologies and varieties having different special function of the PPTA fiber are reviewed and the structure, property and developing prospect of PPTA fiber are introduced in brief.
