负离子纤维素/海藻酸盐复合纤维及其制备方法
摘要：
本发明公开了一种负离子纤维素/海藻酸盐复合纤维及其制备方法，其主要技术要点是，首先在一定工艺条件下制得海藻酸钠粘性溶液和负离子发生体功能整理剂浆料，然后将其按照一定的比例与纤维素黄酸酯混合制得纺丝原液，再经过纺丝和精炼步骤制得负离子纤维素/海藻酸盐复合纤维。该复合纤维主要由纤维素、海藻酸钠和负离子发生体按照下述重量份组成：纤维素99.6～76重量份；海藻酸钠0.02～15重量份；负离子发生体0.02～9重量份。利用该复合纤维制成的织物，除具有抗菌、护肤、促进伤口愈合等保健作用外，还具有负离子发生功能和更高的强度和湿模量，不仅适合于医疗卫生领域，而且也特别适合用做各种贴身内衣、儿童服装及高档服饰。
摘要（英）：

The present invention discloses a kind of composite negative ion cellulose/alginate fiber and its preparation process. Technologically, the present invention features that viscous sodium alginate solution prepared in certain technological condition, functional finishing agent slurry of negative ion generating material and cellulose xanthate in certain weight proportion are mixed to form the spinning solution, and the through further spinning and refining steps, the composite negative ion cellulose/alginate fiber is prepared. The composite fiber consists of cellulose 76-99.6 weight portions, sodium alginate 0.02-15 weight portions and negative ion generating material 0.02-9 weight portions. The composite fiber may be used in weaving fabric with the functions of killing bacteria, protecting skin, promoting wound healing, generating negative ion, etc. and is suitable for use in medical field and in making various kinds of high grade underwear, etc.
