本发明公开了一种内置空隙式亚麻包覆XLA纤维的包芯纱的制备方法，包括亚麻处理、配置中间层、涂附中间层、包芯；本发明将亚麻弹力包芯纱通过120至130℃的温度进行加热固化15至20min，使得中间层受热固化，提高亚麻细纱、中间层、XLA弹力纤维长丝附着度，同时更重要的是将碳酸镁进行发泡，如此中间层会有断断续续的空隙发泡出来，使得中间层本身、中间层与亚麻细纱之间、中间层与XLA弹力纤维长丝之间均能产生一定大小的空隙以提高回弹性能。
Description
技术领域
本发明涉及一种内置空隙式亚麻包覆XLA纤维的包芯纱的制备方法。
背景技术
亚麻制品历史悠久，在世界范围享有盛誉，即使在丝绸、纯棉、毛、人造纤维等织品十分发达的今天，亚麻织物仍占有不可替代的高贵地位。亚麻天然的透气性、吸湿性、清爽性和排性，使其成为自由呼吸的纺织品，常温下能使人体室感温度下降4-8℃，被称为“天然空调”。目前亚麻弹力面料一般是通过亚麻包覆弹性纤维长丝，形成亚麻弹力包芯纱进行织造，但是这种亚麻弹力纱的亚麻纤维与弹性纤维长丝的附着度不好，长时间使用后会出现亚麻纤维与弹性纤维长丝分离现象，造成产品质量问题。
发明内容
针对上述现有技术的不足之处，本发明解决的问题为：提供一种结构稳固、弹性恢复度高的内置空隙式亚麻包覆XLA纤维的包芯纱的制备方法。
为解决上述问题，本发明采取的技术方案如下：
一种内置空隙式亚麻包覆XLA纤维的包芯纱的制备方法，步骤如下：
S1、亚麻处理：选用分裂度指标大于等于250支的原麻，并将原麻打成麻；向麻喷淋含有加湿剂的水溶液进行加湿；然后用成条机制成麻条，将麻条依次走并条机纺成粗纱；将粗纱依次进行复配酶脱胶处理、堆仓、酸洗、亚漂、碱洗、氧漂、水洗；将粗纱使用细纺纱机加捻制成细纱；将亚麻细纱进行烘干络筒；
S2、配置中间层；将竹纤维研磨成粉末形态，将纳米三氧化二铝粉末10～20份、六方氮化硼粉末5～10份、竹纤维粉末20～30份、碳酸镁粉末4～8份、环氧树脂粉末10～15份按照比例进行混合，加水进行搅拌后待用，得到中间层糊料；
S3、涂附中间层：将中间层糊料导入浸渍槽内，将XLA弹力纤维长丝经过中间层糊料，最后于30至50℃中进行加热5至10min，形成涂附有中间层的XLA弹力纤维长丝；
S4、包芯：将步骤S1中的亚麻细纱与步骤S3中的涂附有中间层的XLA弹力纤维长丝通过细纱机纺成亚麻包覆中间层的亚麻弹力包芯纱；将亚麻弹力包芯纱通过120至130℃的温度进行加热固化15至20min，提高亚麻细纱、中间层、XLA弹力纤维长丝附着度，同时将碳酸镁进行发泡，使得中间层产生空隙以提高回弹性能；
进一步，所述步骤S1中保湿18～36小时；并条机共计5道。
进一步，所述步骤S1中，取果胶酶、脂肪酶、木聚糖酶、纤柔酶四种酶按照3:2:1:1的比例复配后，经过三级发酵制成脱胶酶液；所述脱胶通过将亚麻粗纱浸入脱胶酶液中1小时进行生物脱胶。
进一步，所述步骤S2中加水量与各组分的质量比为2:1，搅拌时间为20至30min。
进一步，所述步骤S4中，在细纱机安装减速器和变频器完成对XLA弹力纤维长丝的牵伸可控，并加装张力控制器使纱更平直。
进一步，所述步骤S5中，采用一正一反轻烧毛，油量控制在18kg/h，车速在120m/min，烧毛质量达3级。
进一步，所述步骤S5中，一次定型的温度为150～155℃；二次定型的温度为170～180℃。
本发明的有益效果
1.本发明将亚麻弹力包芯纱通过120至130℃的温度进行加热固化15至20min，使得中间层受热固化，提高亚麻细纱、中间层、XLA弹力纤维长丝附着度，同时更重要的是将碳酸镁进行发泡，如此中间层会有断断续续的空隙发泡出来，使得中间层本身、中间层与亚麻细纱之间、中间层与XLA弹力纤维长丝之间均能产生一定大小的空隙以提高回弹性能。
2.本发明在亚麻细纱和XLA弹力纤维长丝之间增设了中间层，本发明的中间层包含了纳米三氧化二铝、六方氮化硼、竹纤维、碳酸镁、环氧树脂，纳米氧化铝提高了整个组分的分散性以及流动性，如此使得XLA弹力纤维长丝在经过中间层糊料时更加的顺畅以及避免过多的中间层糊料涂附于XLA弹力纤维长丝上，同时提高整个体系的均匀分散性；六方氮化硼为六面晶体叠加结构，具有极大的表面比，如此提高了中间层与XLA弹力纤维长丝以及亚麻细纱的附着度；环氧树脂协同提供一定的粘接效果；通过竹纤维的高透气吸湿性可以弥补因为设置了中间层而带给产品的透气和吸湿性能的缺失，上述各组分进行协同配合，得到适用于本发明的中间层，极大的提高了XLA弹力纤维长丝、中间层、亚麻细纱之间连接的连接强度，实现了稳固的连接。

一种内置空隙式亚麻包覆XLA纤维的包芯纱的制备方法，步骤如下：
S1、亚麻处理：选用分裂度指标大于等于250支的原麻，并将原麻打成麻；向麻喷淋含有加湿剂的水溶液进行加湿；然后用成条机制成麻条，将麻条依次走并条机纺成粗纱；将粗纱依次进行复配酶脱胶处理、堆仓、酸洗、亚漂、碱洗、氧漂、水洗；将粗纱使用细纺纱机加捻制成细纱；将亚麻细纱进行烘干络筒；保湿36小时；并条机共计5道；取果胶酶、脂肪酶、木聚糖酶、纤柔酶四种酶按照3:2:1:1的比例复配后，经过三级发酵制成脱胶酶液；所述脱胶通过将亚麻粗纱浸入脱胶酶液中1小时进行生物脱胶。
S2、配置中间层；将竹纤维研磨成粉末形态，将纳米三氧化二铝20份粉末、六方氮化硼10份粉末、竹纤维30份粉末、碳酸镁8份粉末、环氧树脂15份粉末按照比例进行混合，加水进行搅拌后待用，得到中间层糊料；加水量与各组分的质量比为2:1，搅拌时间为30min。
S3、涂附中间层：将中间层糊料导入浸渍槽内，将XLA弹力纤维长丝经过中间层糊料，最后于至50℃中进行加热10min，形成涂附有中间层的XLA弹力纤维长丝。
S4、包芯：将步骤S1中的亚麻细纱与步骤S3中的涂附有中间层的XLA弹力纤维长丝通过细纱机纺成亚麻包覆中间层的亚麻弹力包芯纱；将亚麻弹力包芯纱通过130℃的温度进行加热固化20min，提高亚麻细纱、中间层、XLA弹力纤维长丝附着度，同时将碳酸镁进行发泡，使得中间层产生空隙以提高回弹性能；在细纱机安装减速器和变频器完成对XLA弹力纤维长丝的牵伸可控，并加装张力控制器使纱更平直。
如图1所示，本发明在亚麻细纱3和XLA弹力纤维长丝1之间增设了中间层2，本发明的中间层包含了纳米三氧化二铝、六方氮化硼、竹纤维、碳酸镁、环氧树脂，纳米氧化铝提高了整个组分的分散性以及流动性，如此使得XLA弹力纤维长丝在经过中间层糊料时更加的顺畅以及避免过多的中间层糊料涂附于XLA弹力纤维长丝上，同时提高整个体系的均匀分散性；六方氮化硼为六面晶体叠加结构，具有极大的表面比，如此提高了中间层与XLA弹力纤维长丝以及亚麻细纱的附着度；环氧树脂协同提供一定的粘接效果；通过竹纤维的高透气吸湿性可以弥补因为设置了中间层而带给产品的透气和吸湿性能的缺失，上述各组分进行协同配合，得到适用于本发明的中间层，实现了亚麻细纱3、XLA弹力纤维长丝1与中间层2连接的稳固性。
如图1所示，本发明将亚麻弹力包芯纱通过120至130℃的温度进行加热固化15至20min，使得中间层2受热固化，提高亚麻细纱3、中间层2、XLA弹力纤维长丝1附着度，同时更重要的是将碳酸镁进行发泡，如此中间层2会有断断续续的空隙21发泡出来，使得中间层本身、中间层与亚麻细纱、中间层与XLA弹力纤维长丝均产生一定的空隙21以提高回弹性能。
本发明亚麻弹力包芯纱的性能测试如下。
上述可知，本发明的结构强度、弹性恢复性能、以及各层之间的撕裂强度均达到很高的水平。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
