Abstract
本发明公开了一种凝胶化改性纤维静电纺丝面膜的制备方法，此面膜的功能层包括凝胶保湿层和固态精华释放层，其中所述的凝胶保湿层采用天然纤维素原位凝胶化改性技术制备而成，所制备的凝胶化改性纤维无纺布凝胶是新型的无纺布凝胶，其主要成分是羟乙基纤维素。而固态精华释放层采用静电纺丝技术，将液态精华液制备成固态精华膜，解决了细菌与真菌的腐败滋生问题，从而提高了面膜的存储时间，又解决了使用过程中造成的精华液浪费和滴液问题。通过两种技术的有机结合制备出保湿性、敷贴性、便捷性俱佳的固态面膜，提高了面膜的使用效果。
Description
技术领域
本发明属于面膜领域，具体涉及一种凝胶化改性纤维静电纺丝面膜的制备方法。
背景技术
纤维素是地球上历史最悠久、储量最丰富的天然高分子。其取之不尽用之不竭，是人类最宝贵的天然可再生资源。纤维素化学与工业始于160多年前，是高分子化学诞生及发展时期的主要研究对象。目前，基布面膜大多数都是纤维素材质，然而纤维素柔顺性很差，敷贴性也不佳。因此需要对纤维素无纺布进行改性，增加其敷贴性和无纺布的柔顺性。在纤维素无纺布改性中，大多数人都是将其改性为羧甲基纤维素。如，发明专利CN109674721A公开了一种羧甲基纤维素面膜的制备方法，其使用先碱化再浸轧一氯乙酸的方法进行羧甲基纤维素的制备，然后将羧甲基纤维素通过静电纺丝纺制成无纺布，最后再加入面膜液，虽然面膜布敷贴性有所提高，但是制备过程过于繁琐复杂。
从吉尔伯特首次发现当液滴置于摩擦过的琥珀附近时，液滴的表面会变形为锥体的这一发现，到1934~1944年间，福姆哈尔斯发明了三种静电纺丝实验设备，再到1971年，鲍姆加登将可以批量生产丙烯酸纤维的设备的研制成，再到，如今世界各地对静电纺丝纳米纤维的研究掀起来了纳米科技热，静电纺丝这项技术已经发展了400多年。目前，无论是学术领域还是工业领域都普遍认为，静电纺丝技术是21世纪纳米纤维工业化最有希望的工艺方法。静电纺丝技术的发展，使得固态精华面膜变成了可能。
因此，一种制备简单、敷贴性佳、易存储、精华少浪费的面膜成为面膜企业和大众所追求的目标。
发明内容
本发明针对上述目前面膜制备过程中存在的问题，以及人们对使用更高端的面膜产品的需求，提供一种凝胶化改性纤维静电纺丝面膜的制备方法。本发明不仅使用了原位凝胶化改性纤维技术对纤维素无纺布进行了凝胶化改性，还使用静电纺丝技术对凝胶化改性无纺布进行了固态精华纳米纤维的制备，此两种技术结合在一起而制备的面膜，将面膜推向一个全新的高度，提供了全新的概念——凝胶化改性纤维静电纺丝面膜，为面膜制备技术的迭代升级提供了全新的可行性方案。
为解决上述的技术问题，满足上述的技术要求，本发明采用如下具体技术方案：
(1)无纺布纤维碱化：将42 g/m2天然纤维素无纺布完全浸入适量质量分数为10~40 %的碱液中，在30~55 ℃下，进行碱化15~35 min后，挤压干净无纺布中多余的碱液，备用；
(2)无纺布纤维醚化：在碱化反应后的干无纺布中低温加入具有稀释剂保护的醚化剂10~30 mL，在40~70 ℃下，进行醚化35~60 min后，加入pH中和液，将pH值调节至5.5~7.0，用75 %稀释剂水溶液洗涤3~5次，每次洗涤时间为15 min，最后用高温压干机压干且平整，备用；
(3)静电纺丝前驱液配置：将聚乙烯醇加入适量乙醇水溶液中，加热至95 ℃，搅拌直至溶解均匀，降温至40 ℃，再依次加入透明质酸钠和聚乙烯基吡咯烷酮，继续搅拌直至溶解均匀，继续降温至室温，再依次加入芦荟提取液、维生素C、烟酰胺，继续搅拌直至形成均相的纺丝前驱液；
(4)无纺布静电纺丝：将上述制备的凝胶化无纺布固定在静电纺丝接收器上，使用5~20 mL的注射抽取适量上述的纺丝前驱液，将注射器放在往复平台的注射器推进器上，进行静电纺丝制备纳米纤维后，得到凝胶化改性纤维静电纺丝面膜。
优选地，所述的碱液为氢氧化钾、氢氧化钠、三乙醇胺、尿素中两种以上的混合水溶液，所述的稀释剂为丙酮、异丙醇、叔丁醇中的一种，所述的醚化剂为环氧乙烷，所述的pH中和液为85 %磷酸、冰乙酸、盐酸中的一种。
优选地，所述的天然纤维素无纺布与所用碱液的质量比为1~3:96~100。
优选地，所述静电纺丝前驱液的成分组成，透明质酸钠1~5份、聚乙烯醇15~35份、聚乙烯基吡咯烷酮0.5~1.3份、烟酰胺3~5份、维生素C 0.5~1份、芦荟提取液5~10份、无水乙醇15~45份、纯化水30~60份，其中，无水乙醇与纯化水的体积比为1~3:2~4。
优选地，所述的静电纺丝的相关参数，高压直流电压为14~20 kV，纺丝距离10~20cm，注射器推进速率为 0.8~1.8 mL/h，针头型号为19~22 G，往复平台转轴转速为300~550rpm，接收器转速为400~550 rpm。
本发明所具有的有益效果如下：
本发明的天然纤维素无纺布凝胶化改性大幅改善了无纺布的柔顺性，从而提高了无纺布的面部敷贴性。与此同时，还增加了天然纤维素无纺布的保湿性以及润滑舒适性。本发明所进行的凝胶化改性纤维的无纺布凝胶是新型的无纺布凝胶，其主要成分为羟乙基纤维素。其无味无毒，溶于热水或冷水，高温或煮沸不沉淀，保湿性能佳。
本发明采用静电纺丝技术将液态精华液制备成固态精华膜，既解决了细菌与真菌的腐败滋生问题，从而提高了面膜的存储时间，又解决了使用过程中造成的精华液浪费和滴液问题。本发明中通过两种技术的有机结合，使得精华液的吸收更加充分，提高了面膜的使用效果。
