Description

一种新型高强透气电热织物及其制备方法
技术领域
本发明属于纺织品领域，具体涉及一种新型高强透气电热织物及其制备方法。
背景技术
随着电阻加热时获取电热的一种主要形式。电热材料形式很多，包括金属型电热材料和非金属型电热材料、刚性电热材料和柔性电热材料。低电阻纤维也可作为电热材料的一种，可用于构成电热织物。CN114657793A专利中公布了一种基于铜纳米线的电热织物，通过将铜纳米线浸渍到织物表面，形成表面电加热层。CN113651593A专利公布了一种氧化石墨烯气凝胶，用于构建电热织物。但目前，电热织物难以同时兼顾柔性、高强、透气性，对实际应用有一定限制。
发明内容
发明目的：本发明针对电热织物的柔性、高强和热湿舒适性的问题，提供了一种新型高强透气电热织物及其制备方法，可以实现柔性、高强、透气电热织物的连续生产。
为实现上述目的，本发明提供如下技术方案：一种新型高强透气电热织物，所述织物由高特低电阻纬纱和低特高电阻经纱构成。所述低电阻纬纱采用包芯纱结构，且其芯纱是由低电阻纤维构成的股线，其鞘纱为高电阻纤维；所述织物纬向两端的纬纱头端与耐高温导线相连。
优选的，所述低电阻纬纱的芯纱所用低电阻纤维的电阻值为(10-104)Ω·cm。
优选的，所述芯纱是由2股高捻单纱合股而成的股纱，确保纤维紧密抱合，其中单纱细度为(300-1200)tex。
优选的，芯纱原料采用石墨烯改性有机纤维、金属改性纤维和低电阻有机纤维等，纤维直径为(10-100)μm。
优选地，所述低电阻纬纱的鞘纱所采用纤维的电阻值大于107Ω·cm，回潮率大于4％。
优选的，所述经纱细度为(80-120)tex，所采用纤维的电阻值大于107Ω·cm，回潮率大于4％。
优选的，经纱和鞘纱原料采用阻燃PVA纤维和阻燃粘胶纤维等。
优选的，耐高温导线选用铜导线，其导电部分与纬纱头端间通过粘结或绑接的方式相连，并外覆绝缘层。
本发明还提供了一种高强透气电热织物的制备方法，包括以下步骤：
步骤1)、制备低电阻股线：采用低电阻纤维原料，经环锭纺精梳纱工艺制得低电阻高捻度单纱后，将2股低电阻高捻度单纱反向合股加捻制得低电阻股线；
步骤2)、制备高电阻单纱：采用高电阻纤维原料，经环锭纺工艺分别制得高电阻低捻度单纱和高电阻高捻度单纱；
步骤3)、制备包芯纱：以步骤1)中低电阻股线为芯，以步骤2)中高电阻低捻度单纱为皮，在细纱机上制得包芯纱；
步骤4)、制备电热织物：以步骤3)中包芯纱为纬纱，以步骤2)中高电阻高捻度单纱为经纱，以铜导线为织物的两侧经纱，在织机上织的织物后，将纬纱与铜导线进行粘结或绑接处理，并在连接处贴敷绝缘层，制得电热织物。
与现有技术相比，本发明的有益效果是：
本发明的一种新型高强透气电热织物，通过纬纱内部的低电阻芯纱发挥电发热效果；纬纱表层的鞘纱一方面隔绝和保护纬纱的作用，另一方面赋予纱线一定的吸湿性，防止燥热，确保热湿舒适性；纬纱的芯纱采用股线结构，强度更高。通过调控纱线粗细和织物密度，可实现(40-150)W发热功率的电热织物连续生产，且具有柔软、舒适、透气等多方面特性。
