摘要
在半精纺纺纱设备上试纺2.2 dtex×38 mm聚酰亚胺短纤维,由于聚酰亚胺纤维刚性大、表面光滑、纤维抱合性能差,在纺纱前对纤维进行了预处理,改善其可纺性,成功纺制了14.5 tex聚酰亚胺纱线。并对所纺纱线试织织物的保暖性能进行了测试,结果表明其保暖性能优异,热阻值可达同规格纯棉织物的2.33倍,在民生保暖产品领域具有潜在的应用价值。
Polyimide staple fibers with linear density of 2.2 dtex and length of 38 mm are spun on semi-worsted spinning machines. Because of its high rigidity, smooth surface and poor fiber cohesion, the fibers are pre-treated to improve the spinability. The 14.5 tex polyimide yarn is successfully spun. The thermal retention property of the fabric made from polyimide yarn is tested. The results show that the fabric has excellent thermal retention property, which is 2.33 times of the pure cotton fabric with the same specifications. The polyimide fiber fabric has potential practical value in the field of livelihood thermal products.
