Abstract
本发明公开了一种防紫外线的运动服用锦氨空气包覆丝的生产工艺,能够使锦氨空气包覆丝具有良好的抗紫外线性能,同时还能够长久保持透气舒爽的体验,有效降低静电的产生与聚集,保证肌肤的健康,利于在户外运动服装面料的纺织中使用与推广。
Description
【技术领域】
本发明涉及化工纺织的技术领域,特别是一种防紫外线的运动服用锦氨空气包覆丝的生产工艺的技术领域。
【背景技术】
随着纺织面料品种需求的不断扩大,各类特种纤维,特殊加工工艺,特殊风格的纱线应运而生,锦氨空包丝是近年来市场上较为流行的一种特色纱线。它是以氨纶丝为芯,与锦纶长丝包缠复合而成。氨纶和锦纶的交织,不仅可以使织物可在常温常压下染色,避免高温高压对织物的损伤,而且使得针织物具有吸湿透气,手感柔软、有弹性和回复性,满足了人们对服装穿着舒适,贴身和保持外形不变的要求,被广泛用于袜品、内衣、运动衣等。然而常规的锦氨空包丝不具备防紫外线的功能,同时也不具备防静电、抗辐射等有利于身体健康的功能。而紫外线在日光中约占6%,其中UV-A的比例较大,UV-B比例较小。UV-A会透过表皮组织下面,使肌肉失去弹性,皮肤粗糙,造成皱纹,UV-B则有致皮肤癌问题。同时静电和辐射无处不在,同样也会对人体产生不良的影响。
【发明内容】
本发明的目的就是解决现有技术中的问题,提出一种防紫外线的运动服用锦氨空气包覆丝的生产工艺,能够使锦氨空气包覆丝具有良好的抗紫外线性能,同时还能够长久保持透气舒爽的体验,有效降低静电的产生与聚集,保证肌肤的健康,利于在户外运动服装面料的纺织中使用与推广。
为实现上述目的,本发明提出了一种防紫外线的运动服用锦氨空气包覆丝的生产工艺,依次包括以下步骤:
步骤一:将锦纶切片、二氧化钛、木炭纤维、聚乙烯蜡、氯化锌和硫酸钠在氮气保护下喂入料仓,进入挤压系统,在挤压机内经过各区段加热,在265~285℃熔融搅拌混合,制成锦纶原液并保温;
步骤二:将步骤一制备的锦纶原液经过粗砂和细砂过滤后送入计量泵,计量泵将锦纶原液输送至纺丝箱,纺丝箱通过喷丝板喷制出锦纶原丝;
步骤三:对步骤二制备的锦纶原丝进行侧吹风冷却,冷却风温度为20~22℃,环境湿度为70~79%,冷却风速为0.8~1.0m/s;
步骤四:对步骤三冷却后的锦纶原丝进行均匀打孔并上油,将锦纶丝收卷在原丝架上,完成锦纶丝制备;
步骤五:.将锦纶丝由原丝架引出,经由假捻变形机的第一切丝器依次进入喂丝罗拉、止捻器、牵伸罗拉、变形热箱加热,进入牵伸罗拉,再进入冷却装置,从假捻器引出后,由吸枪吸住;
步骤六:将氨纶丝经由假捻变形机的第二切丝器依次进入喂丝罗拉、止捻器、牵伸罗拉、变形热箱加热,进入牵伸罗拉,再进入冷却装置,从假捻器引出后,由吸枪吸住;
步骤七:以步骤六制备的氨纶丝为芯纱,以步骤五制备的多根锦纶丝为外皮纱,经过网络喷嘴的气流将锦纶丝和氨纶丝包缠在一起,通过牵伸罗拉、变形热箱加热,进入牵伸罗拉,冷却装置,再通过上油罗拉上油后收卷,制成锦氨空气包覆丝。
作为优选,所述步骤一中各组分的质量份数比为:锦纶切片:70~80份;二氧化钛:5~8份;木炭纤维:20~30份;聚乙烯蜡:10~20份;氯化锌:8~12份;硫酸钠10~15份。
作为优选,所述步骤一中的挤压机内各区段加热温度依次递增,各区段加热温度的递增范围为5~10℃,各区段加热过程中需要对熔融液进行不断搅拌。
作为优选,所述步骤五中的变形热箱温度为190~200℃,所述假捻器的速比为D/Y为2.2,所述步骤六中的的变形热箱温度为170~180℃,所述假捻器的速比为D/Y为3.2。
作为优选,所述氨纶丝为十字异形氨纶丝,所述氨纶丝内填充有烷基化双酚。
本发明的有益效果:本发明能够使锦氨空气包覆丝具有良好的抗紫外线性能,同时还能够长久保持透气舒爽的体验,有效降低静电的产生与聚集,保证肌肤的健康,利于在户外运动服装面料的纺织中使用与推广。
