摘要：

为制备同时具有抗菌和防细菌黏附功能的棉织物,采用光控葡萄糖氧化酶体系引发自由基聚合反应,分别以[2-(甲基丙烯酰基氧基)乙基]二甲基-(3-磺酸丙基)氢氧化铵(SBMA)或甲基丙烯酸二甲氨基乙酯(DMAEMA)与3-(异丁烯酰氧)丙基三甲氧基硅烷(TMSPMA)聚合,得到防细菌黏附聚合物P(TMSPMA-co-SBMA)和抗菌聚合物P(TMSPMA-co-DMAEMA)。然后,通过浸渍-焙烘法将2种聚合物单独或共同整理到棉织物上。测试了整理织物的化学结构、表面元素含量、抗菌性能、防死/活细菌黏附性能等。结果表明:2种聚合物成功整理到棉织物上;抗菌整理棉织物抑菌率达到99.9%,表面较多死细菌;防细菌黏附整理棉织物具有85%以上抑菌率,表面黏附的死/活细菌均较少;抗菌防细菌黏附棉织物抑菌率与防活细菌黏附率达到98%和81%以上,且织物表面可防止死细菌黏附。

Abstract:

In order to prepare cotton fabrics with both antibacterial and antibacterial adhesion functions, free radical polymerization of [2-(methacryloyloxy)ethyl] dimethyl-(3-sulfopropyl) (SBMA) or 2-(dimethylamino) ethyl methacrylate (DMAEMA) with 3-(trimethoxysilyl)propyl methacry-late (TMSPMA) was produced utilizing a light-controlled glucose oxidase system to obtain antibacterial adhesive polymer P(TMSPMA-co-SBMA) or antibacterial polymer P(TMSPMA-co-DMAEMA). The two polymers were individually or jointly applied to the cotton fabric using the impregnation-baking method. The chemical structure, element composition, antibacterial properties and anti-dead/live bacteria adhesion properties of the finished fabrics were measured. The results show successful adhesion of two polymers on the cotton fabric. The antibacterial agent finished cotton fabric has a bacteriostatic rate of 99.9% with many dead bacteria on the surface, and the antibacterial adhesion agent finished cotton fabric shows a bacteriostatic rate of more than 85% but with less dead/live bacteria adhering to the fabric surface. The antibacterial and antibacterial adhesion rates of cotton fabrics exceed 98% and 81%, and the surface of the fabric can prevent dead bacteria from adhering.
