Description

改善原液着色面料左右色差的生产工艺
技术领域
本发明涉及原液着色面料的生产工艺技术领域，具体涉及一种改善原液着色面料左右色差的生产工艺。
背景技术
原液着色面料由于在生产过程中就赋予纤维各种颜色，因此，在染整过程中省去了染色环节，节能减排，对环境友好，目前已经成为一种较为成熟的环保型生产方式，并得到越来越多的品牌厂商和客户的认可，发展潜力巨大。
但在色母粒造粒过程中，由于切片和色母粒混合不匀、造粒机的喷丝孔频繁开停，影响色母粒的色度均匀；或者计量孔磨损，造成色母粒经过计量盘后下落不匀，产生色差；或者在生产同一批产品时，由于原料波动或工艺设计不合理，导致纤维结果变化，引起色差。抑或在纺纱过程中，绕纱时间和捻系数差异等，均对纤维和纤维集合体色差产生较大影响。
因此在大批量生产过程中，原液着色面料不可避免的存在着边中色差及色光不一致的情况，直接影响了面料品质。由于染色环节在纱线生产过程中已完结，在染整环节缺失，因此，无法有效的控制面料边中边左右色差的问题。
所以，为了解决以上问题，急需一种理想的技术解决方案。

所述的改善原液着色面料左右色差的生产工艺，包括以下工艺步骤：
(1)烧毛：车速100m/min，透烧，火焰强度20mbar；
(2)退浆：退浆酶：4g/L，渗透剂：4g/L，萃取剂：4g/L，精炼酶5g/L，车速：80m/min蒸箱温度：100℃；汽蒸时间：15min；
(3)拉幅：工作液包括：渗透剂4g/L，柔软剂FUN 6220:40g/L。然后将工作液加入轧槽内，浸轧原液着色面料，2浸2轧，轧余率65％，烘房温度120℃，上风量为80％，下风量为70％，排风为40％。
表1实施例1、2、3、4和对比例1、2制备的面料的毛效测试结果
Figure BDA0003371944890000061
由上表看出，面料经向毛效，实施例1、2较改善前的对比例1、2高1.0-1.9cm；面料纬向毛效，实施例1、2较改善前的对比例1、2高0.4-0.7cm。同时，实施例1、2原液着色面料边中经向毛效差异均在0.3cm以内；而对比例1、2面料边中经向毛效差异在0.8cm以上。说明改善后的原液着色面料毛效更好，边中吸湿效果差异更小。
表2实施例1、2、3、4和对比例1、2制备面料的左中右色差测试结果
Figure BDA0003371944890000062
Figure BDA0003371944890000071
由上表可知，面料边中色差机测ΔE，实施例1、2边中最大差值为0.04-0.07；而对比例1、2边中最大差值为0.13-0.17，说明改善后的原液着色面料边中色差更小。同时，移染牢度实施例均在4-5级，较对比例高1-2级；皂洗牢度实施例均在4-5级，较对比例高1级。
当然，上述内容仅为本发明的较佳实施例，不能被认为用于限定对本发明的实施例范围。本发明也并不仅限于上述举例，本技术领域的普通技术人员在本发明的实质范围内所做出的均等变化与改进等，均应归属于本发明的专利涵盖范围内。
