氨纶包芯纱的弹性与其织物缩率的关系
|
摘要
长丝的牵伸倍数是在纺制氨纶包芯纱时的重要参数,包芯纱的捻度、织机筘幅及织物经纬密度都与织物缩率有直接关系。分析了包芯纱捻度、长丝牵伸倍数与缩率的关系。结果表明:其他条件相同时,坯布的缩率会随着捻度的增加而减小,随着氨纶丝牵伸倍数的增加而增加,平纹缩率﹥斜纹缩率﹥缎纹缩率。
The draft multiple of polyurethane fiber is an important parameter in core spun yarn, and there are direct relations among twist of corn-spun yarn, loom reed size and textile density with the shrinkage of textile. The relation among twist, pre-draw multiple and shrink of fabrics were analyzed. The results show that the shrinkage of fabric decreased with the increase of twist, while increased with the draft ratio of polyurethane, and the rangeability of fabric shrinkage was as follow: plain ﹥ twill ﹥ satin.
