Description
技术领域
本发明为涉及水刺用织造材料的制备方法,尤其是良好吸湿、透气的水刺用织造材料的制备方法。
背景技术
纯棉水刺非织造材料是一种新型的纤维材料,因其具有柔软、蓬松、舒适、吸湿性好、不含非纤维组分等特点被广泛应用于医疗卫生、生活用品、工业用品等领域。料与人体皮肤接触时,棉纤维能迅速将水分和汗液吸附到材料上,得非发挥很好的作用。
但纯棉织物的后整理中常用烧碱处理,容易造成的试样发生了收缩,厚度增加,导致纤维之间孔隙率增加,这增大了可吸液的面积,使碱处理后的试样对液体具有良好的吸收性能拒水整理工艺实施后,整理剂会与纤维形成化学结合并牢固地附着于纤维表面,故纯棉水刺非织造布的透气性会有所下降,但因水刺非织造布中有孔洞的存在,局部拒水整理后的纯棉水刺非织造布仍会保持着良好的透气性。因此,最终获得的凹凸褶皱型纯棉水刺非织造布在具有天然棉纤维特性的同时,还具备良好的吸液性、蓬松性、单向导湿性( 如某些特定工艺的产品) 等,产品可用于面膜和卫生护理用品等领域。
201710333440.2一种医用透气可降解水刺无纺布是采用一种医用透气可降解水刺无纺布,包括表层和里层,所述表层和里层通过水刺复合为一体;其中,所述表层为聚乳酸纤维和竹炭纤维的混纺层;所述里层为桑蚕丝、聚乳酸纤维和甲壳素纤维的混纺层。本发明一种医用透气可降解水刺无纺布,其通过各种功能纤维的合理使用和水刺成孔效果,一方面赋予水刺无纺布优异的广谱抗菌性能,另一方面赋予水刺无纺布优异的可降解性能、透气性能和柔软亲肤效果,对伤口有良好的愈合效果,在医用产品上具有广阔的市场前景。
