摘　　要：某些工厂的作业环境中充满了挥发性有机化合物气体,在这种环境中工作的人员必须穿着具有一定防护功能的服装,以防止这些挥发性特质对健康造成损害.本文探讨抗挥发性有机化合物沾染织物的加工工艺.给出了几种加工整理方法,以减少服装面料对挥发性有机物质的沾染.包括使用不同的纤维材料制作织物,减少织物的面密度,织物与PTFE微孔膜复合,以及使用含氟整理剂或有机硅整理剂整理织物等.实验中,使用上述方法加工的织物暴露在富含挥发性有机化合物合溶胶的氛围中24h,然后取出用二硫化碳萃取织物上粘附的有机化合物,利用气相色谱分析技术检测其含量.检测结果显示,不同纤维制作的面密度相同的织物,对各种挥发性有机物质的染性能差别不大.但是,通过降低织物的面密度,或者将织物与PTFE微孔膜复合,或者使用含氟整理剂或有机硅整理织物,均可有效降低织物对挥发性有机化合物的沾染.Staffs in the factories with VOC aerosols should wear clothing with protective profermances. The process technique fabric resisting contamination by volatile organic compounds（VOC） was researhed. Some methods were introduced such as fabricating fabrics with different fibers, reducing the weight per square meter of the fabric, laminating the fabric with PTFE membrane and finishing the fabric with fluorine-containing agents or silicone for reducing VOC adsorption by the fabric. Fabrics made by above methods were exposed in the full of VOC environment aerosols for 24h. Then the VOCs adhered to the samples were extracted with CS2 and analyzed by gas chromatography. The Test results indicate that fabrics with same weight per square meter but fabricated from different fibers have similar resistance to the contamination by VOCs. However, fabrics with low weight per square meter, or laminated with PTFE membrane, or finished by the fluorine-containing finishing agents or silicone, all improved resistance to the contamination by VOCs.
