Description

一种亲水抗菌型无纺布制备工艺
技术领域
本发明涉及无纺布加工技术领域，尤其涉及一种亲水抗菌型无纺布制备工艺。
背景技术
无纺布又称不织布，是通过一定技术生产出的由定向的或随机的纤维而构成的材料，因具有布的外观和性能而称其为布。
无纺布应用领域较广，其中在医疗卫生、家庭装饰和服装应用领域上，需要更加适合与人体接触，但现有的无纺布(如涤棉无纺布)，其复合层中的涤纶层抗菌效果较差，容易滋生螨虫、细菌等危害人体健康的物质，而且其亲水效果不好，透气性较差，穿着后容易产生发闷的感觉，降低了人体个穿着体验，不太适合家居和穿着使用，因此需要一种可以具有优异亲水透气效果、且能抗菌的无纺布。
发明内容
本发明的目的在于提供一种亲水抗菌型无纺布制备工艺，以解决上述背景技术中所提出的问题。
为达到上述目的，本发明采用的技术方案是：一种亲水抗菌型无纺布制备工艺，包括如下步骤，
S1)采用浸渍法对涤纶抗菌短纤进行亲水整理，将亲水整理后的涤纶抗菌短纤脱水、烘干、开松、梳理，制得涤纶层；
S2)将天然纤维开松、梳理，制得下层棉，在下层棉上喷洒抗菌整理剂，喷涂的压力控制在2-2.5kg，烘干速度20m/min，烘干时温度160-200℃，喷涂时烘干一次，为保证产品完全烘干，可再烘干一次，烘干速度30m/min；另外，亦可采用浸渍法制备下层棉；
S3)将涤纶层和下层棉经过热轧或水刺，制得复合层；
S4)在复合层上表面均匀喷涂柔软处理液，在160-180℃条件下进行烘干，柔软处理剂可选用有机硅型柔软剂，使得无纺布具有较好的柔软效果，与人体接触更加舒适；
S5)将烘干后的复合层修剪、裁切，即可制得亲水抗菌型无纺布。
作为进一步的优化，所述涤纶抗菌短纤亲水整理工艺为:使用涤纶整理剂2-10％(o.w.f)，浴比为1:(8-10)，浸渍时间为20-30min，浸渍温度为40±2℃。
作为进一步的优化，所述涤纶抗菌短纤维为银系抗菌短纤。
作为进一步的优化，所述涤纶整理剂(吸湿排汗剂)为T200或T200B。
作为进一步的优化，所述抗菌整理剂用量为20-50g/L。
作为进一步的优化，所述天然纤维为棉纤维、蚕丝纤维或粘胶纤维，其长度为3-5cm。
作为进一步的优化，所述抗菌整理剂为胍类抗菌剂或季铵盐类抗菌剂。
作为进一步的优化，S1和S2中的烘干温度为100±5℃。
作为进一步的优化，复合层为经热轧成型。
作为进一步的优化，复合层为经水刺成型，水刺压力为10-80Mpa。
与已有技术相比，本发明的有益效果体现在：
1.经复合制备的无纺布具有优异的亲水性和抗菌性，适合家居、穿着等于人体皮肤接触的条件下使用；
2.涤纶层采用抗菌短纤制备，同时对下层棉进行抗菌整理，使得无纺布整体具有优异的抗菌性，而且银系抗菌短纤具有持久的抗菌效果，耐多次洗涤；涤纶层经过吸湿排汗剂整理，具有良好的亲水性透气性，与天然纤维具有的亲水性共同作用，使得无纺布整体具有优异的亲水性；
3.本发明所使用的各种助剂均具有环保性，因此制备的无纺布具有优异的环保属性。
