抗起球腈纶的染色工艺研究

摘要

从染色温度、染料对纤维的质量分数（owf）和染色时间等影响因素入手，结合匀染性测试，研究并确定了Na．SCN法抗起球腈纶的染色工艺，并对其染色前后的力学性能进行了比较。结果表明：抗起球腈纶的玻璃化转变温度约为90℃，在owf为0．5～1．O％，升温速率为1K／min，染色温度为105℃，保温时间为60min的染色条件下，纤维的匀染性较好，染色条件对抗起球特性指标影响不大。%The dyeing process for NaSCN method anti - pilling acrylic fiber was determined based on study of the affecting factors as dyeing temperature, on weight the fabric （owf）, and dyeing time, connecting with leveling property test.
