Description
技术领域
本发明属于非织造复合材料及其制备技术领域,具体涉及一种水溶性纳米纤维复合非织造医美材料,并且还涉及其制备方法。
背景技术
随着人们生活水平的不断提高,属于医疗和美容范畴的非织造医美产品具有广泛的生产空间,通过表面涂覆、浸渍等后整理制备非织造医美产品是目前普遍使用的技术手段。然而,功能性物质和基材的相容性差、功能材料团聚、处理后非织造布透气性和机械性能下降等问题依然制约着医美非织造材料的开发进程。
随着对纳米技术研究的不断深入,获得直径分布从数个纳米到数百个纳米纤维的静电纺丝技术日益成熟。由于静电纺丝纳米纤维具有较大的比表面积、丰富的孔道结构、灵活的表面功能化特性和优越的界面及表面效应,因而被广泛应用于诸如能源、环境、生物科学、医学工程、军事及国家安全等领域。就尺寸而言,由于纳米纤维的直径小于细胞,因而可以模拟天然的细胞外基质结构和生物功能,是优异的细胞黏附、增殖和生长模板。
虽然静电纺丝技术的设备及工艺不断完善,产量也相应地显著提高,但是与传统熔喷、纺粘制备技术相比,其生产能力难以满足迫切的产业应用需求。此外,单一纳米纤维构建的纳米纤维膜还存在强力低的问题。鉴此,开发得以弥补前述技术问题的非织造复合材料具有积极意义,下面将要介绍的技术方案便是在这种背景下产生的。

A)将微米纤维原料依次经开松机开松、梳理机梳理和铺网机铺置于接收网帘上,得到微米纤维棉网层;
B)将水溶性高分子材料溶于作为溶剂的去离子水或乙醇溶剂中,水浴加热充分搅拌,并且控制水浴加热的水浴温度以及控制在搅拌状态下的水浴水加热的时间,再加入医美功能性材料常温搅拌并且控制常温搅拌的时间,得到水溶性高分子材料的质量百分含量为13-17%以及医美功能性材料的质量百分含量为3-5%的静电纺丝用纺丝液;

E)在调节步骤A)中所述的微米纤维棉网层的克重、行进速度以及控制步骤C)中所述的无针式喷头的配置数量的状态下将所述微米纤维棉网层与静电纺丝纳米纤维层的质量比控制为98-102∶1,并且重复步骤A)以及步骤E)复数次,得到待水刺或针刺的复合微纳米纤维层;
