Description

一种高生物相容性水刺无纺布
技术领域
本发明涉及织物领域,特别地涉及一种高生物相容性水刺无纺布。
背景技术
随着时代的发展,人们越来越重视对个人肤质的保养,面膜已成为一种常见的护肤品。面膜的基本功能是将皮肤与外界隔绝,使皮肤温度升高,毛孔大量出汗,皮肤的分泌活动旺盛,在剥离面膜时,将皮肤分泌物、皮屑、污物等除掉,使毛孔清洁的同时将面膜中的营养物质有效渗入皮肤里,起到增进皮肤机能的作用。成型类面膜是由面膜基材经折叠入袋后加入精华液制成的。
理想的面膜基材应具备以下性能:良好的持水性;优异的贴面度;良好的生物相容性;良好的力学性能;可降解、无污染。细菌纤维素(Bacterial cellulose,简称BC)是由微生物发酵合成的多孔性网状纳米级生物高分子聚合物,因其由细菌合成而命名为细菌纤维素。它由独特的丝状纤维组成,纤维直径在0.01~0.10μm之间,每一丝状纤维由一定数量的超微纤维组成网状结构,作为一种新型纳米材料,细菌纤维素已应用于纺织、医用材料、食品等各个领域,现已成为国际的研究热点。
日前,细菌纤维素大规模产业化应用还存在一些问题,例如成本高、产量低及机械稳定性差等,本发明提供一种高生物相容性水刺无纺布,其以改性细菌纤维素为主要原材料,成本低廉、机械稳定性强、吸水能力强,生物相容性高,是优秀的面膜基材。
发明内容
为了解决上述技术问题,本发明提供一种高生物相容性水刺无纺布。
本发明是以如下技术方案实现的:
一种高生物相容性水刺无纺布,所述水刺无纺布的主要成分为细菌纤维素及苎麻纤维。
进一步地,所述水刺无纺布的制作步骤如下:
步骤一、获得准备好的细菌纤维素及苎麻纤维,所述细菌纤维素与苎麻纤维质量比为3:1,将上述细菌纤维素及苎麻纤维浸泡于市售软化整理剂中,室温下放置24h,之后分别进行开松、除杂,将已开松的纤维喂入纤维仓,将细菌纤维素与苎麻纤维制成均匀的纤网,进入梳理工序。
步骤二、梳理工序采用两梳一铺生产线,由一台梳理机输出的纤网首先喂给交叉铺网机进行铺网,紧接着由牵引机对铺叠后的纤网进行牵伸,再与另一台梳理机输出的纤网叠加成为双层纤网后送至水刺机。
步骤三、由步骤二获得的双层纤网经过预湿后进行正反水刺,制备不同组分水刺无纺布过程中,水刺液不同,水刺液中加入透明质酸,预湿水压为1bar,水刺压力为35bar,控制喷射的时间为1.5-3min,生产线速度为25米/分,之后55℃烘干获得所述高生物相容性水刺无纺布。
进一步地,所述细菌纤维素获得自大量培养后的转基因细菌。
进一步地,所述细菌为醋醅类芽孢杆菌。
进一步地,所述转基因细菌包括一种纤维素表达增强相关基因,所述纤维素表达增强相关基因的核苷酸序列如SEQ ID NO.1所示。
本发明的有益效果在于:高生物相容性水刺无纺布耐撕扯性能显著优于市售无纺布,吸水倍数达122-135倍,透气性高达702-714CFM,不会闷气,舒适度高,可以有效抑制细菌、真菌生长;纤维损伤率低于0.2‰,有效解决纤维掉毛问题,触感柔软,接近纯棉布,并且耐撕扯,可机洗,表明本发明提供的水刺无纺布具有高生物相容性,对于皮肤无刺激,对于敏感肌肤无致敏现象。针对现今细菌纤维素价格较高、不利于工业生产应用的缺陷,本发明提供一种通过基因改造以获得高产细菌纤维素的菌种及途径,以弥补现有技术的缺失。
