摘要
为获得调温功能和耐水洗性能均较佳的调温纺织品,利用相变微胶囊优异的调温性能和包芯纱特殊的皮芯结构开发了一种调温纱线.首先对涤纶长丝芯纱进行改性预处理,再将其作为调温功能载体进行相变微胶囊浸渍整理,最后外包棉纤维制备成相变调温包芯纱.测试结果表明:设计的摩擦粗糙化处理能够有效改善涤纶长丝表面的结合性能,使其承载更多的相变微胶囊,相比于未改性的涤纶长丝,其织物相变微胶囊负载率高出45.7％;与包芯纱直接浸渍整理相比,芯纱浸渍整理的相变调温包芯纱织物的调温时间更长,水洗10次后质量保留率更高.
Abstract
In order to obtain temperature regulating textiles with excellent temperature regulation function and washing resistance,a temperature regulating yam is developed by utilizing the excellent temperature regulation performance of phase change microcapsules and the special skin core structure of core-spun yarns.Firstly,the polyester filament core yarn is modified and pretreated,and then used as a temperature regulating functional carrier for phase change microcapsule impregnation finishing.Finally,the phase change temperature regulating core yarn is prepared by wrapping it with cotton fibers.The performance test results show that the designed friction roughening treatment can effectively improve the bonding performance of the surface of polyester filament,so that it can carry more phase change microcapsules,and the loading rate of fabric phase change microcapsules is 45.7％higher than that of unmodified polyester filament.Compared with the direct impregnation and finishing of core yarn,the phase change temperature adjustment core yarn fabric with core yarn impregnation finishing has a longer temperature adjustment time and a higher weight retention rate after 10 washes.
