Description

一种高强力羊毛化纤混纺物及生产方法
技术领域
本申请涉及纺织物的领域，更具体地说，它涉及一种高强力羊毛化纤混纺物及生产方法。
背景技术
羊毛纤维具有弹性优异、吸湿透气和防污防臭等优点，然而其强力较低，通常与强力化纤混纺从而提升纺织物强度。
在羊毛混纺面料生产过程中，为了提高纺织物的阻燃性能，通常采用的方式为使用氟锆酸盐对纺织物进行后整理，氟锆酸盐经水洗或者受热燃烧产生ZrOF2覆盖在纤维表面，起到阻燃的作用。
经氟锆酸盐后整理的纺织物经过多次洗涤之后，纤维表面覆盖的ZrOF2脱落，从而导致纺织物的阻燃性能下降。
发明内容
为了提高纺织物的阻燃耐久性，本申请提供一种高强力羊毛化纤混纺物及生产方法。
第一方面，本申请提供一种高强力羊毛化纤混纺物的生产方法，采用如下的技术方案：
一种高强力羊毛化纤混纺物的生产方法，包括以下步骤：S1、将羊毛纤维制成精梳条，将阻燃纤维和高强锦纶6纤维分别制成熟条，S2、将S1制得的三种纤维条并条，先制得粗纱再制得细纱并进行络筒工序处理；S3、将细纱织造成混纺面料；S4、将混纺面料进行阻燃整理后得到混纺物。
通过采用上述技术方案，先将羊毛纤维、阻燃纤维和高强锦纶6纤维制成混纺面料，此时混纺面料满足强力和阻燃等功能，再通过阻燃整理进一步提高混纺面料的阻燃性能，并且通过阻燃整理使得混纺面料的防水性得以提升，减少水洗导致混纺面料阻燃性能下降的情况。
优选的，所述阻燃整理包括以下步骤：将混纺面料使用阻燃整理剂处理，经二浸二轧，控制轧液率为60％～70％，然后100℃烘干1～2h，再置于190～195℃环境中焙烘1～2min，水洗并烘干。
通过采用上述技术方案，混纺面料经阻燃整理后形成混纺物，阻燃整理剂提高混纺面料的阻燃性能的防水性能，减少水洗对混纺物阻燃性能的影响。
优选的，所述阻燃整理剂包括阻燃剂、连接剂和防水固化剂，所述阻燃剂、连接剂和防水固化剂三者重量之比为(6～10):(2～4):1。
通过采用上述技术方案，由于采用连接剂将阻燃剂和防水固化剂连接于纤维上，在进行阻燃整理时，防水固化剂通过固化提高连接剂对阻燃剂与纤维的连接效果，从而使得阻燃剂与纤维之间的连接强度增加，当混纺物进行清洗时，防水固化剂有效减少水分对混纺物阻燃整理效果的影响，从而有效延长纺织物的阻燃耐久性。
优选的，所述连接剂包括水杨酸乙基己酯和水杨酸已癸酯，所述水杨酸乙基己酯和水杨酸已癸酯二者重量之比为(1～3):1。
通过采用上述技术方案，水杨酸乙基己酯和水杨酸已癸酯一方面通过化学键使得阻燃剂更容易结合于纤维上，另一方面作为中间连接介质使得阻燃剂与防水固化剂之间的连接强度得以提升。
优选的，所述防水固化剂包括苯丙乳液和有机硅丙烯酸乳液，所述苯丙乳液和有机硅丙烯酸乳液二者重量之比为1:(1～3)。
通过采用上述技术方案，防水固化剂在阻燃整理过程中附着于混纺面料上，以连接剂作为中间介质与阻燃剂以及混纺面料的连接强度增大，从而使得混纺物的防水性能提升。
优选的，所述阻燃剂为三聚磷酸铝溶液。
通过采用上述技术方案，使用溶剂将三聚磷酸铝配置成溶液，从而便于根据实际浸润需求调整阻燃整理剂的浓度。
第二方面，本申请提供一种高强力羊毛化纤混纺物，采用如下的技术方案：
一种高强力羊毛化纤混纺物，由混纺面料经阻燃整理而来，所述混纺面料由包括以下重量份的原料组成：羊毛纤维30～50份，阻燃纤维50～60份，高强锦纶6纤维20～30份。
通过采用上述技术方案，将阻燃纤维与羊毛纤维以及高强锦纶6纤维混纺成面料，从而使得面料的阻燃性能提升，并且减少水洗对面料阻燃性能的影响。
优选的，所述阻燃纤维包括聚乙烯醇溶液、氢氧化铝、戊二醛和碳化硅，所述聚乙烯醇溶液、氢氧化铝、戊二醛和碳化硅四者重量之比为(15～20):(3～5):1:(2～4)。
通过采用上述技术方案，利用戊二醛促进聚乙烯醇交联从而将氢氧化铝与碳化硅固定共同组成阻燃纤维，在维持阻燃性能的同时提高阻燃纤维的防水性能，减少水洗对面料阻燃性能的影响。
综上所述，本申请具有以下有益效果：
1、本申请的高强力羊毛化纤混纺物在阻燃整理过程中，阻燃剂和防水固化剂通过连接剂与混纺面料的连接强度增加，并且防水固化剂以连接剂为中间介质与阻燃剂连接强度增加，提高阻燃剂在混纺面料上的连接稳定性，从而减少水洗对混纺物阻燃性能的不良影响。
2、本申请中水杨酸乙基己酯和水杨酸已癸酯与阻燃剂以及防水固化剂交联，从而有效提高防水固化剂与阻燃剂之间的连接强度。
3、本申请中使用高强锦纶6纤维、阻燃纤维和羊毛纤维制得混纺面料，在提高混纺面料阻燃性能的同时，有效提高阻燃整理剂与混纺面料的结合强度，进而提高阻燃整理剂在混纺面料上的稳定性，减少水洗对混纺物阻燃性能的不良影响。

表1性能检测数据表
结合实施例2和对比例1-3并结合表1可以看出，由于采用连接剂将阻燃剂和防水固化剂连接于纤维上，在进行阻燃整理时，防水固化剂通过固化提高连接剂对阻燃剂与纤维的连接效果，从而使得阻燃剂与纤维之间的连接强度增加，当混纺物进行清洗时，防水固化剂有效减少水分对混纺物阻燃整理效果的影响，从而有效延长纺织物的阻燃耐久性。
结合实施例2和对比例3-5并结合表1可以看出，通过将阻燃整理剂附着于混纺面料上，连接剂使得防水固化剂和阻燃剂均与阻燃纤维连接，从而有效提高阻燃剂的附着强度，有效延长纺织物的阻燃耐久性。
结合实施例2、实施例4和实施例5并结合表1可以看出，水杨酸乙基己酯和水杨酸已癸酯配合使用，一方面通过化学键使得阻燃剂更容易结合于纤维上，另一方面作为中间连接介质使得阻燃剂与防水固化剂之间的连接强度得以提升。
结合实施例2、实施例6和实施例7并结合表1可以看出，苯丙乳液和有机硅丙烯酸乳液配合使用，有利于防水固化剂固化，从而便于连接剂将防水固化剂与阻燃纤维等连接，提高防水性能。
本具体实施例仅仅是对本申请的解释，其并不是对本申请的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本申请的权利要求范围内都受到专利法的保护。
