Description
技术领域
本发明涉及纺织用品技术领域,具体涉及一种纳米防污抑菌纺织面料及其制备方法。
背景技术
随着人们生活水平的提高,纺织面料在一定程度上需要防污抗菌功能。目前抗菌面料主要采用两种方式,一种是利用天然纤维自身具有的抗菌、吸湿、保健功能,另一种是采用处理技术,将具有抗菌功能的微粒或离子添加或浸渍到面料中。第一种方法虽然具有更高的环保健康性,但其往往抗菌性能不够,满足不了抗抗菌要求的面料,而第二种方法在进行防污和抗菌处理时,由于外界引入的方法不同,其抗菌效果不佳,并且稳定性较差,经多次水洗后会出现抗菌效果大大减弱的现象。
中国专利CN112144281A公开了一种防污防水的面料,包括基体布料和防污防水处理剂,其中,防污防水处理剂由以下原料按重量份组成:水溶性丙烯酸树脂10~25份、月桂醇聚氧乙烯醚5~17份、纳米二氧化硅6~12份、蓖麻油3~8份、硬脂酸2~8份、乳化剂3~5份、偶联剂1~3份、交联剂1~3份、去离子水50~80份。但该专利制备的防污防水面料的亲肤性较差。
中国专利CN106003899A公开了一种抑菌防紫外线面料,包括表层、防晒层、抑菌层以及内层,所述表层由棉纤维构成;所述防晒层由涤纶纤维、尼龙纤维以及牛津纤维构成,其中涤纶纤维所占的质量比为25-30%,尼龙纤维所占的质量比为25-30%,牛津纤维所占的质量比为40-50%;所述抑菌层由银离子、玻璃纤维以及涤纶纤维构成,其中银离子所占的质量比为5-10%;所述内层由棉纤维构成。但该专利制备的抗菌防紫外线面料的抗菌效果不持久,不耐水洗。
发明内容
有鉴于此,本发明提供一种纳米防污抑菌纺织面料及其制备方法,以解决上述技术问题。
为实现上述目的,本发明提供如下技术方案:一种纳米防污抑菌纺织面料,所述纳米防污抑菌纺织面料由外至内依次包括防污层、抗菌基层和亲肤层;所述防污层由涤纶纤维、再生涤棉短纤维和亚麻纤维混纺纱织造而成;所述抗菌基层由棉纤维和氨纶纤维混纺织造而成;所述亲肤层以竹纤维、海藻纤维的混纺纱为经线,棉纤维为纬线进行织造而成;所述防污层中涤纶纤维、再生涤棉短纤维和亚麻纤维的质量比为10:(4~8):(2~4);所述抗菌层中棉纤维和氨纶纤维的质量比为(3~4):(6~7)。
其中,在抗菌基层的表面设置防污层,不仅可以减少复合纳米抗菌剂在日常使用和洗涤时的损失,还可以提高面料的疏水性,使细菌杂质难于附着在织物表面,或者即使附着后也容易被流水等外力冲洗脱落,提高织物的防污抗菌性能;在抗菌基层内侧设置亲肤层,可以提高面料与肌肤接触时的舒适感,改善穿着体验。
进一步地,所述亲肤层的经线中竹纤维和海藻纤维的质量比为(6~8):(2~4)。
进一步地,所述防污层、抗菌基层和亲肤层的质量比为(2~4):10:(1~2.5)。

步骤S20,将步骤S10得到的涤纶/涤棉/亚麻混纺纱浸入防污剂溶液中,经烘干得到防污涤纶/涤棉/亚麻混纺纱;所述防污剂为市售防污剂,苯二甲酸乙二酯防污剂,在防污剂溶液中的浓度为13g/L;
步骤S30,将所述质量比的棉纤维和氨纶纤维放到抗菌整理液中,抗菌整理液的浓度为5~60g/L,35~50℃下浸泡3~6小时,在105℃的温度下热风烘干,再进行混纺,得到棉纤维/氨纶混纺纱;
步骤S40,以竹纤维、海藻纤维的混纺纱为经线,棉纤维为纬线进行织造而成,得到亲肤层;
步骤S50,将步骤S20得到的防污涤纶/涤棉/亚麻混纺纱和步骤S30得到的棉纤维/氨纶混纺纱同时喂入纬编针织机中,进行弯纱成圈,使防污涤纶/涤棉/亚麻混纺纱在外层,棉纤维/氨纶混纺纱在里层,得到防污抗菌复合层;
步骤S60,将步骤S40得到的亲肤层和步骤S50得到的防污抗菌复合层以粘合或缝合的方式连接,得到纳米防污抑菌纺织面料。
进一步地,所述抗菌整理液为含有复合纳米抗菌剂的溶液。
进一步地,所述复合纳米抗菌剂的制备包括:将酪素放到浓度为4%~8%的醋酸溶液中,混合均匀后得到酪素的醋酸溶液;将纳米抗菌剂、司盘60溶解在乙醇溶液中,加入步骤S10得到的酪素的醋酸溶液,以900~1100r/min的搅拌速度搅拌混合0.5小时~2.5小时,冷却后放置冰箱中-10~-16℃保存5~10小时,从冰箱取出升温至室温后抽滤,并用石油醚清洗两次,减压干燥3~4.5小时,得到复合纳米抗菌剂;所述复合纳米抗菌剂的粒径在5~20nm。
进一步地,所述搅拌混合的温度为38~52℃。
进一步地,所述纳米抗菌剂为纳米二氧化钛载银抗菌剂、氧化锌以重量比10:2~4混合。
进一步地,所述酪素和纳米抗菌剂的质量比为10:2.5~5。
进一步地,所述减压干燥的温度控制在38~48℃。
从上述的技术方案可以看出,本发明的优点是:
1.本发明纳米防污抑菌纺织面料在抗菌基层的表面设置防污层,不仅可以减少复合纳米抗菌剂在日常使用和洗涤时的损失,还可以提高面料的疏水性,使细菌杂质难于附着在织物表面,或者即使附着后也容易被流水等外力冲洗脱落,提高织物的防污抗菌性能,在抗菌基层内侧设置亲肤层,可以提高面料与肌肤接触时的舒适感,改善穿着体验;
2.本发明纳米防污抑菌纺织面料通过预制复合纳米抗菌剂,采用酪素对纳米二氧化钛载银抗菌剂和氧化锌进行包裹,提高其在溶液中的分散性以及在面料中的分布均匀性,并且将有效抗菌组分进行处理,提高其在日常穿着和洗涤时的稳定性,延长抗菌抑菌时效;
3.本发明制备的纳米防污抑菌纺织面料的抗污性好,表面污渍易清洗,抗菌性能优异,并且抗菌效果持久,耐洗性强,制备方法简单,加工工艺易操作,适合工业化生产加工。

步骤S20,将质量比为3.5:7.5的棉纤维和氨纶纤维放到抗菌整理液中,抗菌整理液的浓度为32g/L,42℃下浸泡4.5小时,在105℃的温度下热风烘干,再进行混纺,得到棉纤维/氨纶混纺纱;上述抗菌整理液为含有纳米抗菌剂的溶液;纳米抗菌剂为纳米二氧化钛载银抗菌剂、氧化锌以重量比10:3混合;
步骤S30,以质量比为7:3的竹纤维、海藻纤维的混纺纱为经线,棉纤维为纬线进行织造而成,得到亲肤层;
步骤S40,将步骤S10得到的涤纶/涤棉/亚麻混纺纱和步骤S20得到的棉纤维/氨纶混纺纱同时喂入纬编针织机中,进行弯纱成圈,使防污涤纶/涤棉/亚麻混纺纱在外层,棉纤维/氨纶混纺纱在里层,得到防污抗菌复合层;
步骤S50,将步骤S30得到的亲肤层和步骤S40得到的防污抗菌复合层以粘合或缝合的方式连接,得到纳米防污抑菌纺织面料。
