【摘要】 本文用聚丙烯腈、丙烯酸甲酯和甲基丙烯磺酸钠、三元共聚物的硫氰酸钠溶液进行湿法纺丝,研究了纺丝液的温度和聚合物含量,纺丝速度及拉伸与水洗工序的先后顺序对纤维的结构和染色性的影响。结果发现,采用先拉伸后水洗与先水洗后拉伸两种工艺,纺得纤维的染色性和结构有明显差别。更多还原

【Abstract】 The effects of spinning process on the structure and dyeing behavior of acrylic fibers was studied in the paper, The spinning parameters studied included the temperature of the spinning solution, polymer concentration, spinning speed, the change of drawing operation and washing operation. The results show that the change of the process of formation from drawing before washing to drawing after washing considerable effected the structure and dyeing behavior of acrylic fibers.更多还原
