Description
技术领域
本发明涉及羊毛精纺面料生产技术领域,具体涉及一种天然抗菌羊绒精纺面料的生产工艺。
背景技术
羊毛织物具有良好的弹性、保暖型和吸湿性,其主要成分为蛋白质,羊毛纤维的微孔结构及角蛋白成分为细菌滋生提供了水分及营养,羊毛纤维的抗菌整理主要采用后整理工艺,即通过负载各类抗菌剂赋予织物特种功能。常用的抗菌整理剂按照机理可总结为两类:一是利用抗菌剂中的阳离子基团通过静电作用吸附到带负电的细菌细胞壁,它们能够破坏细胞壁结构、抑制蛋白合成、使细胞合成酶失活,还可通过改变细胞壁通透性,使细胞内溶物渗出达到抗菌效果;二是利用纳米材料的小尺寸效应和光化学活性,在光催化条件下产生强氧化基团与微生物反应导致细菌死亡。
常见的天然抗菌剂包括壳聚糖、溶菌酶、聚赖氨酸和植物多酚。其中壳聚糖和聚赖氨酸具有一定成膜能力,能与羊毛纤维的蛋白质分子发生交联。溶菌酶和植物多酚在溶液中处于有利状态,难以与羊毛纤维结合。

S2:将氨基硅氧烷分散于纯水中,得到透明的氨基硅氧烷溶胶;
S3:将羊绒精纺面料浸渍于S1所得甲氧基硅烷溶胶抗菌整理液中,浸轧烘干,然后将羊绒尽让面料浸渍于S2所得氨基硅氧烷溶胶中,浸轧焙烘,所述焙烘温度为110~140℃,焙烘时间为1~3min。
优选的技术方案为,所述植物多酚为五倍子酚、牡丹酚、茶多酚中的一种或两种以上的组合。
优选的技术方案为,S1中的有机溶剂为选自甲醇、乙醇、乙二醇和丙酮中的一种或两种以上的组合。
优选的技术方案为,植物多酚、甲醛与缩水甘油醚氧丙基三甲氧基硅烷的重量之比为(0.3~1):(0.01~0.03):10,甲氧基硅烷溶胶抗菌整理液中缩水甘油醚氧丙基三甲氧基硅烷与酸性水溶液的重量之比为(0.3~1):10。
优选的技术方案为,氨基硅氧烷溶胶中氨基硅氧烷与水的重量之比为(0.1~0.7):10。
本发明的优点和有益效果在于:
该天然抗菌羊绒精纺面料的生产工艺利用硅氧烷溶胶将植物多酚固定到羊毛纤维上,所得羊绒精纺面料具有良好的防毡缩性能和抗菌性能,并且抗菌性能具有较高的热稳定性,满足服用要求。
