摘要
为了提高军用三角包扎巾的性能,采用抗静电剂对聚酰亚胺纤维进行预处理并设计混纺纱工艺流程,以聚酰亚胺纤维和新丽赛纤维为原料,成功纺制聚酰亚胺纤维含量为30％,40％和50％,号数为18.4 tex的混纺纱;对混纺纱的强力、毛羽和条干不匀率进行测试分析,利用模糊综合评价法综合评判出最优混纺比例纱线并试织小样、测试指标.指出:当聚酰亚胺纤维含量增大时,混纺纱的强伸性能增强,毛羽和条干性能逐渐恶化;聚酰亚胺纤维比电阻高、回潮率低,在纺纱时需要对其进行抗静电预处理;聚酰亚胺纤维/新丽赛纤维混纺比例为50/50的纱线综合性能最好,所制三角包扎巾满足YY/T 1467-2016标准要求,且具有止血抗菌性能.
Abstract
In order to improve the performance of military triangular bandage,polyimide fiber is pretreated with antistatic agent and the blended yarn process is designed.The blended yarn with 30％,40％and 50％polyimide fiber and number of 18.4 tex are successfully spun by tak-ing polyimide fiber and new-richcel fiber as raw materials.The strength,hairiness and uneven-ness of the blended yarn are tested and analyzed.The optimal blended proportion yarn is evalu-ated by fuzzy comprehensive evaluation method,the sample is tired to weave,and indexes are tested.It is pointed out that when the content of polyimide fiber increases,the strength and e-longation of the blended yarn enhance,and the hairiness and evenness properties deteriorate gradually.Polyimide fiber has high specific resistance and low moisture regain,so it needs anti-static pretreatment during spinning.Yarn with 50/50 blending ratio of polyimide fiber/new-richcel fiber has the best comprehensive performance,and the triangular bandage produced meets the requirements of YY/T 1467-2016 standard,and has hemostatic and antibacterial properties.
