摘　　要：低温阳离子可染涤纶沸水收缩率高,在与纤维素纤维配伍生产针织产品时会带来外观平整度难以控制的问题.为了制备低沸水收缩率的低温阳离子可染涤纶,研究了后道牵伸改性中的热盘温度和热盘速度对纤维微细结构和沸水收缩率的影响,并获得了热盘温度在150～200℃、热盘速度在450～550 m/min的较合适工艺条件.研究表明,在一定的温度条件下进行牵伸改性,可以使纤维的沸水收缩率达到与粘胶等再生纤维素纤维接近的水平.其原因是改性后纤维的结晶和取向度获得一定改善.High boiling shrinkage of ECDP limits its applications in products of ECDP and cellulosic fiber blend, for its poor size stability in hot/wetting conditions, resulting in uneven appearance. In this research, the afterward modification technology was performed to improve its boiling shrinkage, and a suitable technological condition was got with a hot disc temperature from 150 -200℃ and a speed of 450 -550m/min. The study indicates that the combined conditions of hot and stretching can significantly improve boiling shrinkage. It is attributed in the increase of crystallinity and the degree of orientation.
