影响PA6浸胶帘子布定负荷伸长率的因素

摘要

In the heat treatment after dipping，constant load elongation of latex ed fabric was affected mainly by temperature and tension in drawing and setting. The constant load elongation of latexed fabric can be controlled within 80% onl y when the constant load elongation raw yarn was smaller than 11.5%。The constan t load elongation of latexed fabric increased when moisture pick-up occurred.%阐述了影响PA6浸胶帘子布定负荷伸长率的因素。结果表明：浸胶热处理工艺中主要是拉伸 区、定型区温度高低、张力大小影响浸胶帘子布定负荷伸长；原丝定负荷伸长率小于11.5% 才能确保浸胶帘子布定负荷伸长小于80%和外观质量；浸胶帘子布吸湿会造成浸胶帘子布定 负荷伸长率增长。
