摘  要:为了比较腈纶基牛奶纤维与腈纶纤维的基本性能,对腈纶基牛奶纤维的表观形态、力学性能、摩擦性能、卷曲弹性等进行了试验.结果表明,腈纶基牛奶纤维的纵向形态有隐条纹和不规则斑点,截面近似圆形并有明显的海岛状凹凸结构和细微孔隙;红外吸收光谱具有羊毛纤维典型的酰胺吸收谱带和腈纶纤维丙烯腈特征谱带;回潮率为4.34%,干、湿态下的断裂强度是腈纶纤维的67%~69%,断裂伸长率是腈纶纤维的1.26~1.27倍;干、湿态初始模量小于腈纶纤维;静、动态摩擦因数也小于腈纶纤维,而卷曲弹性回复率和残留卷曲率均大于腈纶纤维.In order to compare the basic performance of acrylic milk fiber and acrylic fiber, surface morphology, mechanical properties, friction properties and crimp elasticity of acrylic milk fiber were tested. The results showed that the longitudinal morphology of acrylic milk fiber had hidden stripe and irregular spots, and the section of acrylic milk fiber was nearly circular and had obvious insular concave-convex structure and fine pores. The infrared absorption spectroscopy of acrylic milk fiber had typical amide absorption bands of wool fiber and acrylonitrile absorption bands of acrylic fiber. Moisture regain of acrylic milk fiber was 4.34%, the dry and wet breaking strength of acrylic milk fiber was 67%-69% of acrylic fiber; the elongation of acrylic milk fiber was 1.26N1.27 times of acrylic fiber. Dry and wet initial modulus of acrylic milk fiber were less than those of acrylic fiber. Static and dynamic friction factor of acrylic milk fiber were less than those of acrylic fiber, and the crimp recovery rate and residual crimp rate were larger than acrylic fiber.
