抗起球干法腈纶的研究与开发

摘要

分析了干法腈纶纤维抗起球机理，研究了纺丝过程以后的工艺条件，通过降低纤维的钩接强度和钩接伸长，使织物表面的绒毛在摩擦力的作用下自行脱落，不再缠结成球或成球后迅速脱落，以达到提高产品抗起球性能的目的。通过该方法生产的丝束或毛条加工制成织物，抗起球等级可达到3级以上。%This object is to study the theory of fabric pilling and through changing spinning and finishing process of dry acrylic fiber, the loop strength and loop elongation will fall obviously . Using this method, the grade of fabric will be above the 3th by Mart
