Description

一种抗断裂性能优异的抗菌假发及其制备方法
技术领域
本发明涉及假发领域，具体涉及一种抗断裂性能优异的抗菌假发及其制备方法。
背景技术
早在尧舜时期，我国就已经出现了假发，当时的假发绝大多数是发质欠佳或者秃顶的人使用，时至今日，假发已经在各个领域得到了广泛的应用，其中，合成纤维是常用的假发材料之一。
为了赋予假发纤维一定的抗菌性能，中国专利CN201220178257.2采用化学镀工艺在假发丝表面镀制银抗菌膜。但是，该工艺在镀制银后会导致假发的抗断裂性能降低，而且，银属于贵金属，这无疑提高了假发丝的使用成本。针对该问题，有必要设计一种抗断裂性能优异的抗菌假发。
发明内容
针对现有技术存在的问题，本发明旨在提供一种抗断裂性能优异的抗菌假发的制备方法。
一种抗断裂性能优异的抗菌假发的制备方法，其特征在于，所述方法包括如下步骤：
将假发纤维材料悬挂于原子层沉积设备中，加热至85-90℃，并将设备的压力抽至1Pa；
以氩气为吹扫气体，对反应腔室吹扫60-90s，氩气流量为50-55sccm；
导入铜源前驱体，使前驱体吸附于纤维材料表面；
以氩气为吹扫气体，对反应腔室吹扫60-90s，氩气流量为50-55sccm；
导入还原剂，使之吸附于纤维表面并与铜源前驱体反应，进而形成单质铜抗菌膜；
以氩气为吹扫气体，对反应腔室吹扫60-90s，氩气流量为50-55sccm，完成一次单质铜抗菌膜的制备。
循环上述步骤100-500次，得到8.3-42.7nm厚度的单质铜抗菌膜；
所述假发纤维材料的制备方法为：
将由丙烯腈52重量％、偏氯乙烯46.5重量％、苯乙烯磺酸钠1.5重量％制的丙烯酸系聚合物溶于丙酮中，使树脂浓度为26重量％，制得粘度5Pa·s的纺丝原液；
将该纺丝原液使用突起部分的L(长度)/W(宽度)值1.4且具有6个突起沿放射方向连接的截面形状、孔径相当于φ0.3、孔数50个孔的喷丝头，采用0.9的喷丝头牵引系数，在丙酮浓度36重量％的丙酮/水系环境中于20℃下进行纺丝，然后导入53℃的水洗浴中，边水洗边进行1.9倍的预拉伸；
在干热温度125℃及湿球温度80℃的湿热环境气氛下进行干燥恢复失透，实施2.0倍的热拉伸后，在160℃的干热环境气氛下进行10％的松弛热处理，制得假发用纤维材料。
优选地，所述铜源前驱体为二(N-甲基-4-乙基亚氨基-2-戊烯-2-胺化)铜(II)。
优选地，所述还原剂为硼烷。
本发明还提供了一种假发，所述假发由上述方法制备而得。
为了赋予假发用纤维一定的抗菌性能，本发明采用原子层沉积工艺在纤维表面制备一层纳米级的抗菌膜。研究表明，随着抗菌铜膜的厚度增加，假发纤维的抗菌性能得以提高，但是抗断裂性能会降低。为了获得抗菌性能和抗断裂性能都满足使用要求的产品，需将铜抗菌膜的厚度控制在8.3nm-42.7nm之间。
