Description

一种吸湿透气弹力纱线的生产工艺
技术领域
本发明涉及纱线生产技术领域，尤其涉及一种吸湿透气弹力纱线的生产工艺。
背景技术
为了提升面料的耐水洗和耐油污性能，可以在面料表面涂一层防水涂层。同时，通过选择弹性防水涂层胶，既能实现面料的防水，又可以保持面料原有的弹性。
面料的吸湿效果通常是由制成面料的纱线特性决定的，面料表面涂胶后，会形成防水层，使得纱线无法自由进行呼吸，吸湿透气的效果大打折扣，限制了应用范围。
发明内容
本发明的目的在于提供一种吸湿透气弹力纱线的生产工艺，提升耐水洗和耐油污性能，确保吸湿透气的效果。
为达此目的，本发明采用以下技术方案：
一种吸湿透气弹力纱线的生产工艺，包括以下步骤：
坯线的生产，以弹力纤维长丝作为芯丝，外包吸湿短纤维，一起加捻而纺制成坯线，然后进行第一次收卷；
涂胶，对坯线进行第一次放卷，对第一次放卷中的坯线表面涂弹力胶，待弹力胶干燥后形成保护层，进行第二次收卷；
针刺，对坯线进行第二次放卷，经针刺轮进行保护层表面刺破后再进行第三次收卷，得到成品，所述针刺轮外圆上内凹设置有一圈环形槽，所述环形槽中间隔设置有锥形针头，使得锥形针头的尖端刺入坯线而在保护层表面形成密布的气孔。
其中，所述涂胶步骤中，控制收放卷速度，以保持坯线的自然状态。
其中，所述弹力纤维长丝为氨纶长丝或者涤纶弹力纤维长丝。
其中，所述吸湿短纤维为棉纤维或者竹纤维。
其中，所述涂胶步骤中，采用胶盒进行弹力胶的盛放，通过在胶盒中安装的导线轮将坯线导入胶盒实现涂胶。
其中，所述涂胶步骤前，先进行染色，干燥后再进行涂胶。
其中，弹力胶为有机硅高弹涂层胶。
其中，所述环形槽截面为V形结构，所述锥形针头位于V形结构的底部。
本发明的有益效果：一种吸湿透气弹力纱线的生产工艺，特别在坯线的表面涂一层有机硅高弹涂层胶作为柔性的保护层，保持坯线的弹性，提升纱线的耐水洗和耐油污性能，并利用针刺轮在保护层上形成微小的气孔，既不破坏保护层的稳定性，又能保持坯线的“自由呼吸”，具有良好的吸湿和透气的效果，适用范围更加广泛。
具体实施方式
下面通过具体实施例来进一步说明本发明的技术方案。
