摘要
依翡丝纤维是通过在纺丝原液中加入抗菌剂共混制得的具有细旦、抗菌特性的新型改性腈纶纤维。对比依翡丝纤维和普通腈纶纤维的表面形态、力学性能、吸湿性能、比电阻、摩擦性能以及卷曲性能,采用X射线光电子能谱(XPS)对两种纤维的组成和化学键进行分析,并对依翡丝混纺织物的吸湿快干性能和吸湿发热性能进行测试。结果表明:依翡丝纤维横截面为圆形,纵向表面粗糙,有较密的沟槽,具有线密度小、力学性能优异、可纺性高等优点;相比普通腈纶,依翡丝比电阻小,摩擦系数大,不易产生静电。通过XPS分析,得出依翡丝添加的抗菌剂为季铵盐类抗菌剂。依翡丝混纺织物的水分蒸发速率大于0.18 g/h,吸湿发热的最高温升值大于4℃,在吸湿快干和吸湿发热方面都有不错的表现,可用于开发多功能面料。
The Exfresh fiber is a new type of modified acrylic fiber with fine denier and antibacterial properties;it is fabricated by adding an antibacterial agent to the spinning stock solution.The surface morphologies,mechanical properties,moisture absorption properties,specific resistance,friction properties,and curling properties of the Exfresh and ordinary acrylic fibers were tested and compared in this study.The elemental composition and chemical bonds of the two fibers were analyzed via X-ray photoelectron spectroscopy(XPS).Furthermore,the moisture-absorbing quick-drying and moisture-absorbing heat-generating properties of the Exfresh blended fabrics were tested.Results showed that the Exfresh fiber featured a circular cross-section,rough longitudinal surface and dense grooves as well as a low linear density,excellent mechanical properties,and high spinnability.Additionally,it has a lower specific resistance and higher friction coefficient than the ordinary acrylic fiber,thereby making it difficult to produce static electricity.Results of the XPS analysis showed that the added antibacterial agent was a quaternary ammonium salt.Additionally,the evaporation rate of an Exfresh fiber-blended fabric is>0.18 g/h,and its maximum moisture-absorbing heat-generating temperature rise is>4℃.Moreover,it exhibits excellent moisture-absorbing quick-drying and moisture-absorbing heat-generating properties,and can be used to develop multifunctional fabrics.
