Description
技术领域
本发明属于涤纶产品技术领域，具体涉及一种具有良好抗菌性能的涤纶布。
背景技术
涤纶丝是纺织过程中常用的一种丝线，涤纶丝较人造丝坚韧，在进行刺绣时，机器在高速运转，韧度高的涤纶线也可以承受较大的拉力；而且其具有防火性极高的优点，即使衣物接近火焰，也不易触火；再有涤沦丝可以抵受化学物质及经常洗涤，能减少衣物退色及脱色现象，因此一些生产制服、牛仔衣物、运动服或者儿童服装都会用涤纶丝编制的涤纶布进行制造。因此，市场对涤纶布的抗菌性能具有一定的要求，采用具有抗菌性的涤纶布制作的儿童服装，能够更好的保障儿童的健康安全。
发明内容
本发明的目的是针对现有的问题，提供了一种具有良好抗菌性能的涤纶布。
本发明是通过以下技术方案实现的：
一种具有良好抗菌性能的涤纶布，包括以下步骤：
（1）预处理：用氢氧化钠、硫酸钾和分散剂配置成预处理液，然后将涤纶布浸入预处理液中，浸泡15-20min后，预处理液中缓慢加入酸溶液，调节pH值至弱酸性，继续浸泡2小时，然后取出，清水洗涤干净；
（2）浸渍处理：将浸渍液升温至50-55℃，然后将步骤（1）中处理后的涤纶布浸入浸渍液中，进行真空浸渍处理，浸渍时间为2.5-3.0小时，然后取出，在120℃烘干室内烘干，所述浸渍液制备方法为：将纳米二氧化硅均匀分散到去离子水中，配制成质量分数为40%的纳米二氧化硅悬浮液，向纳米二氧化硅悬浮液中添加其质量5%的纳米二氧化钛，搅拌均匀后，再加入摩尔质量比为1:0.06的硝酸锌和硝酸铜，使得纳米二氧化硅悬浮液中硝酸锌的质量浓度为2.5%，加热至80℃，以3000r/min转速搅拌1.5小时，再加入与硝酸锌摩尔比为1:0.5的硫酸，加热至88℃，以1800r/min转速搅拌2小时，再添加纳米二氧化硅质量8%的壳聚糖，搅拌溶液后，即得；
（3）熏蒸：将步骤（2）中处理后的涤纶布用水蒸气进行热蒸1.5-2h，然后冷却至室温，用清水清洗干净，然后烘干，即可；
（4）收卷：将步骤（3）中处理后的涤纶布收卷，入库。
进一步的，所述涤纶布采用的涤纶原料是由精对苯二甲酸（PTA）和乙二醇（EG）为原料经酯化或酯交换和缩聚反应而制得。
进一步的，所述步骤（1）中预处理液每升中含有氢氧化钠1.2g、硫酸钾3.5g，其余为分散剂；所述分散剂为质量分数为5%的乙醇溶液。
进一步的，所述步骤（1）中酸溶液为质量分数为3%的柠檬酸溶液。
进一步的，所述步骤（2）中真空浸渍，真空度为0.025MPa。
进一步的，所述步骤（3）中热蒸温度为105℃。
本发明相比现有技术具有以下优点：本发明通过对涤纶布进行预处理，不仅能够有效的清楚涤纶布表面杂质，同时能够有效的提高涤纶布表面的亲和性，通过采用浸渍剂对涤纶布进行浸渍处理，能够大幅度提高涤纶布表面的抗菌性，通过处理的涤纶布接触细菌时，能够使得细菌细胞壁和细胞膜的负电荷分布不均，干扰细胞壁的合成，从而能够达到抑菌的效果，同时，部分涤纶布表面活性成分能够吸附细菌，然后穿入多孔细胞壁中进入到细胞内，与DNA形成稳定的复合物，干扰DNA聚合酶或RNA聚合酶的作用阻碍DNA或RNA的合成，从而抑制了细菌的繁殖，以此达到高效长久的抗菌的目的；本发明经过大量的试验研究发现，本发明涤纶布对大肠杆菌、白色念珠菌、金黄色葡萄球菌和霉菌的抑制效果最为显著，并且，对细菌的抑制效果明显优于真菌。
