摘要:

为解决自清洁纺织品的耐久性问题,简化加工工艺,以丙烯酸树脂与纳米TiO2 为原料,采用不同的加工工艺,在涤纶机织物表面进行涂层整理,制备了具有自清洁性能的涂层织物,用分解亚甲基蓝的方法对涂层织物的自清洁性能进行表征。采用扫描电子显微镜(SEM)和能谱仪(EDS)对涂层织物的表面形貌及元素组成进行分析。结果表明:不同涂层工艺会影响织物的自清洁效果;一定范围内,涂层织物的自清洁性能随纳米TiO2 质量浓度的增加而提高,当TiO2 质量浓度达到30g/L 时,继续增大TiO2质量浓度,自清洁效果提升不明显;在经过不同类型以及不同次数的摩擦牢度测试后,自清洁效果保持良好。

Abstract:

To solve the durability problem of self-cleaning fabrucs and simplify the process, acrylic resin and nano TiO2 were used to prepare self-cleaning textile. Self-cleaning woven polyester fabrics were prepared by different coating processes, and the degradation of methylene blue was used to evaluate self-cleaning properties thereof. Scanning electron microscope (SEM) and energy dispersive spectrometer (ESD) were used to analyze morphological structures and elementary composition of coating fabrics' surface, respectively. Experimtntal data shows the self-cleaning properties are influenced by different coating processes, and self-cleaning property of fabric improves if more TiO2 is used in limited range. When the dosage of TiO2 reached 30 g/L, self-cleaning property has no lbbious increased with the content of TiO2 increased. The self-cleaning properties of fabrics maintaining well after different types and different times of rubbing fastness tests.
