摘要:
为了研究加弹工艺对原液着色锦纶6弹力丝物理性能与颜色的影响,文章以原液着色蓝色锦纶6预取向丝(87 dtex/24 f)为原料,制备了原液着色蓝色锦纶6弹力丝,探讨了不同牵伸倍数、假捻速比、热箱温度和网络气压下原液着色锦纶6弹力丝的物性指标和颜色特征值。结果表明:原液着色蓝色锦纶6预取向丝经过加弹后,断裂强度增大,断裂伸长率减小,颜色向绿色与蓝色偏移。牵伸倍数1.338,假捻速比1.8,热箱温度165 ℃,网络气压0.5×105 Pa,获得原液着色蓝色锦纶6弹力丝断裂强度、卷曲收缩率、卷曲稳定性较高,物理性能较优。随着热箱温度的升高,纤维明度提高,颜色向绿色、蓝色方向偏移;随着网络气压的增大,纤维明度值和饱和度下降,颜色向红色和蓝色偏移。

Abstract:
To investigate the influence of draw texturing process on properties and color of dope dyed nylon-6 draw textured yarn(DTY), the dope dyed blue nylon-6 pre-oriented yarn(87 dtex/24 f) was used as raw material to prepare the dope dyed blue nylon-6 draw textured yarn. The physical properties and color features of dope dyed blue nylon-6 draw textured yarns under different draw ratios, D/Y ratio, heater temperature and network pressure were discussed. The results showed that after the draw texturing, the breaking strength of the dope dyed blue nylon-6 pre-oriented yarn increased, the breaking elongation decreased, the color turned to green and blue. When the draw ratio was 1.338, D/Y ratio was 1.8, heater temperature was 165 ℃ and network pressure was 0.5×105 Pa, the dope dyed blue nylon 6 DTY was obtained with better breaking strength, crimp contraction, high crimp stability and excellent physical properties. As the heater temperature increased, the fiber brightness increased, and the color turned to green and blue. As the network pressure increased, the fiber brightness and saturation decreased, and the color turned to red and blue.

印染是纺织产业链中提高锦纶附加值的关键环节,能够为纺织服装带来鲜艳色彩与时尚效果。但是,随着国家节能环保政策的实施,环保要求逐年提高,印染行业因染色排放废水废气造成环境污染的问题暴露明显。近年来,环保锦纶的研究,特别是原液着色锦纶的研究迅速发展。
原液着色锦纶是指先对聚酰胺熔体着色后形成有色母粒,再通过添加有色母粒的方式生产原液着色锦纶,在生产过程中使用了具有免染特点的新技术,故符合环保和可持续发展的要求[1-2]。……
