如图3所示，接着执行所述步骤S303，将搅拌后的纺丝液进行纺丝，该纺丝过程可以采用湿法纺丝，具体地，可以将上述纺丝液加入湿法纺丝机反应釜中，并设定纺丝速度在100～110m/min，例如100m/min，纺丝压力为0.2～0.4MPa，例如0.4MPa，纺丝温度为50～60℃， 例如60℃，从而可以始终保持纺丝液处于良好的溶解状态，之后经过直径例如为0.2mm的喷丝孔挤出成型，在该凝固浴可以使用去离子水，该去离子的温度为10～15℃，例如10℃，在该凝固浴下可以实现快速凝固成型得到聚季铵盐/芦荟抗菌纤维。当然并不限定于此，还可以使用酸浴，该酸浴例如为110～120g/L的H2SO4，12～14g/L的ZnSO4，245～255g/L的Na2SO4，例如110g/L H2SO4、12g/L ZnSO4，以及245g/L Na2SO4，酸浴温度为55～60℃，之后可以依序经过牵伸装置、清洗浴、干燥装置、打卷装置，获得所述聚季铵盐/芦荟抗菌纤维。
如图4所示，该聚季铵盐/芦荟抗菌纤维特别适合家纺制品，例如床上用品、澡巾、面巾、方巾等的家纺制品上，所述该聚季铵盐/芦荟抗菌纤维可以和其他天然纤维混纺并最终构成毛巾制品中绕基底层212b的毛圈层212a，以直接摩擦接触肌肤，触感柔软，该混纺过程例如可以将该聚季铵盐/芦荟抗菌纤维和其他纤维例如天然纤维缠绕在混纺机滚辊上，从而可以进行混纺编织，之后再经牵伸、洗涤、干燥得到所述复合纤维面料，该复合面料经过如上所述的抗菌整理剂整理后，抗菌效果明显，而且进一步地降低季铵盐/芦荟抗菌纤维的使用，从而有效降低成本，之后将所述符合纤维面料可以参照GB15979-2002《一次性使用卫生用品卫生标准》溶出性抗(抑)菌产品抑菌性能试验方法进行测试，对大肠杆菌、金黄色葡萄球菌，以及痤疮丙酸杆菌的抑菌效果均达95％以上，进一步地，纤维的断裂强力为0.7～1.2cN/dtex，例如0.9cN/dtex，断裂伸长率为25～40％，例如35％。
如图4所示，在该毛巾制品中，该聚季铵盐/芦荟抗菌纤维可以为任意旦，基于为补足使用韧性的需求，所述聚季铵盐/芦荟抗菌纤维为多纤丝。所述天然纤维可以提高所述毛巾的舒适性，例如丝、棉、毛、亚麻、软毛、毛发、纤维素、苎麻、大麻、亚麻、木质纸浆等在内的天然纤维，在包括本发明提供的聚季铵盐/芦荟抗菌纤维的毛巾制品中，还可以进一步地设计制作印花、割绒毛巾。
图5所示，在本发明公开的另一具体实施方式中，所述面料例如包括壳聚糖季铵盐/海藻复合抗菌纤维，其利用阳离子聚电解质的壳聚糖季铵盐和羧甲基壳聚糖形成共混微胶囊，之后和具有阴离子聚电解质的海藻酸钠的纺丝液进行纺丝时，不易被之后的碱液以及水溶液而破坏，克服难以成型的问题，以及避免了单一壳聚糖季铵盐和海藻酸钠直接进行静电自组装时易团聚结块，纤维易断裂的情况，基于本发明提供的所述壳聚糖季铵盐/海藻复合抗菌纤维基于离子键的强相互作用，有效保证了该复合纤维结构稳定，力学性能好，同时由于纤维所含海藻酸的吸湿性优异，因此纤维的吸湿性能得以提高，而壳聚糖季铵盐和羧甲基壳聚糖具有优异的抗菌性，又使得纤维拥有良好的抗菌性能，即基于具有优异生物相容性、可降解性、 强吸湿性、舒适性的海藻酸钠以及壳聚糖季铵盐的抗菌特性可广泛适用在儿童用的家纺制品，例如儿童被、儿童用毛毯等。本发明公开了如上所述的壳聚糖季铵盐/海藻复合抗菌纤维的制备方法包括但不限于以下步骤：
—S401，将羧甲基壳聚糖水溶液和所述壳聚糖季铵盐的水溶液进行共混得到混合液；

如图5所示，在步骤S401中，所述使用的壳聚糖季铵盐中季铵盐的取代度小于等于30％，当取代度大于30％时，季铵盐的取代度过高，溶解性能低，不利于进行自组装反应，从而影响抗菌性能，碳链长度为6～12，在该范围内抗菌性能明显，该碳链可以破坏细菌细胞膜结构，从而达到抑制细菌的目的。
如图5所示，接着执行步骤S402，将如上所述的混合液中添加乳化剂，例如油包水型的乳化剂，进一步地可以列举聚甘油硬脂酸酯、山梨醇单月桂酸酯、石油磺酸钠、烷基苯磺酸盐、司盘80、月桂醇聚氧乙烯醚、硬脂酸锌等，之后在40～60℃下搅拌乳化5～30min，之后再经过超声处理20～60min，例如30min，以获得相应的共混微胶囊。所述乳化剂添加量相对于所述混合液的重量比为0.1～1％，从而可以满足均匀乳化的要求，所述乳化后共混微胶囊经干燥收集后可以通过马尔文激光衍射粒度分布仪或者扫描电镜进行观察，其粒径范围为6～100nm，进一步地在6～20nm，例如6nm、10nm。
如图5所示，接着执行步骤S403，将上述共混微胶囊加入至海藻酸钠的纺丝液，例如为海藻酸钠的氢氧化钠溶液中，充分搅拌、溶解、过滤后，进行纺丝，该纺丝过程例如可以采用湿法纺丝，并经例如经硫酸锌凝固浴纺丝成型，再将所得纤维清洗、脱硫、上油、干燥，即得到所述壳聚糖季铵盐/海藻复合抗菌纤维。所述海藻酸钠为β-D-甘露糖醛酸(M段)和α-L- 古洛糖醛酸(G段)通过1-4糖苷键连接而成的天然线性高分子，具有良好地抗菌性和吸湿性。
经过如上所述的制备过程获得所述壳聚糖季铵盐/海藻复合抗菌纤维中壳聚糖季铵盐和海藻酸钠的含量可以达到0.5～1，二者之间的作用力强，在多次使用过程中不易结构不易被破坏，具有持续的抗菌、吸湿效果，保持儿童肌肤干爽，免受细菌等的侵扰。
