摘　　要：为解决高收缩聚酯(HSPET)/聚酰胺6(PA6)中空橘瓣型双组分纺黏长丝铺网针刺后存在纤维开纤裂离效果差的问题,对HSPET/PA6针刺布采用干热处理、水热处理、超声波处理和转鼓机洗处理4种物理开纤方式进行分析,并研究了转鼓机洗处理温度和时间对HSPET/PA6针刺布性能的影响。结果表明:HSPET/PA6针刺布的开纤率为18.9%,干热处理后的HSPET/PA6针刺布开纤率并未改变;经水热处理、超声波处理及转鼓机洗处理后的HSPET/PA6针刺布开纤率分别为24.0%、32.6%、75.5%,转鼓机洗能有效提高HSPET/PA6针刺布的开纤率;在最佳转鼓机洗处理温度60℃下,随着转鼓机洗处理时间的延长,开纤率逐渐提高,HSPET/PA6针刺布的柔软度及力学性能随着开纤率的提高逐渐得到改善,而HSPET/PA6针刺布的透气透湿性能逐渐下降。Objective In making nonwoven fabrics,the needling process can not make the two-component fibers split into ultrafine fibers.Because of this,the splitting effect of high shrinkage polyester(HSPET)/polyamide 6(PA6)hollow pie-segmented two-component spunbonded needle-punching nonwovens(hereinafter referred to as the HSPET/PA6 needle-punching nonwovens)is poor,resulting in the HSPET/PA6 needle-punching nonwovens can not give full play to offer the expected performance.It is necessary to identify ways of splitting the fibers in HSPET/PA6 needle-punching nonwovens,and to prepare hollow pie-segmented spunbond needle-punching nonwovens with high fiber splitting rates and excellent performance.Method The two-component spunbonded process was used to prepare HSPET/PA6 hollow pie-segmented spunbonded filaments,and HSPET/PA6 needle-punching nonwovens were formed by mesh lay-up and needle-punching reinforcement.The fiber splitting rates of nonwovens prepared by four different physical fiber splitting processes were compared to find out the optimal process.The softness,mechanical properties as well as air and moisture permeability of HSPET/PA6 needle-punching nonwovens were tested to analyze the effect of the optimal fiber splitting process on the properties of HSPET/PA6 needle-punching nonwovens.Results It was found that the fiber splitting rate of HSPET/PA6 needle-punching nonwovens was 18.9%,and dry heat treatment to the nowovens did not help the fiber splitting rate.However,the fiber splitting rate of HSPET/PA6 needle-punching nonwovens after hydrothermal treatment,ultrasonic treatment and rotary drum machine washing treatment were found to be 24.0%,32.6%and 75.5%,respectively.This indicates that the rotary drum washing can effectively improve the split rate of HSPET/PA6 needle-punching nonwovens,so that the two-component fibers split into ultrafine fibers.Subsequently,the changes in the properties of HSPET/PA6 needle-punching nonwovens before and after the fiber splitting treatment were investigated using the rotary drum m
