Description

一种多功能再生棉纱及其制备方法
技术领域
本发明属于纺织技术领域，具体涉及一种多功能再生棉纱及其制备方法。
背景技术
随着全球人口剧增，世界各国都将控制耕地的利用，棉花、麻、养蚕的桑树的种植都将受到限制，传统棉纺织原料受到多重制约。相关资料显示，2010年国内再生棉纱使用的边角料等原料量共计能达到300万吨左右。按50％的是棉型再生纱来估算，按每亩棉花产量200公斤计算，相当于约700余万亩棉田的产量。再生纱既实现了资源的循环利用，节约了有限的资源，又解决了边角料处理难题，为环境治理作出了贡献。但是由于原料经过开松后，纤维长度缩短、强力下降、耐光性差、容易霉变，这就限制了再生棉纱的利用。
棉纤维含有许多天然共生物，如棉蜡、果胶、含氮物质、灰分以及纺纱过程中的油剂或油污等，这些杂质如不去除会影响浆液在纱线中的渗透和润湿性能，造成上浆不匀。传统的棉纱处理工艺有碱氧一步一浴法和生化法。前者是在高温强碱的状态下对纱线进行处理，能耗大而且会增加纤维的溶胀，影响纱线性能。后者以酶作为前处理剂，虽然降低了前处理温度和生产能耗，但是由于酶自身的使用范围和专一性，也让这种前处理工艺的应用受到了一定的限制，因此，如何得到一种多功能再生棉纱又不会降低力学性能的处理工艺是当前所要解决的技术问题。
发明内容
本发明的目的是提供一种多功能再生棉纱及其制备方法，该再生棉纱可具有抗菌、保暖、抗静电、耐腐蚀、阻燃等多重功效，其制备方法简单，降低生产成本。

优选的，所述步骤(3)中，单次洗涤用水量碎纤维体积的为2-4倍，洗涤时间为10-30min，温度为50-70℃。
优选的，所述步骤(4)中，改性液制备方法为：将纳米竹碳粉、纳米碳酸钙和纳米二氧化硅均匀混合，并与羧甲基纤维素、液体石蜡、透明质酸、醋酸乙烯酯、聚乙二醇一起研磨处理1-2h，得到改性纳米粒子液，再将纳米粒子液与10-40倍质量的清水混合，加热至65-80℃，在1.5-2MPa压力下，以2000-3000r/min转速搅拌30-60min，再自然冷却至室温后即得。
