Applying Softener Doped Silica Coating to Cotton Denim Fabrics

ABSTRACT

Present study, the surface of cotton denim fabrics which are one of the most used products in daily life was modified with silica coatings prepared with sol-gel technique. Cationic and nonionic softeners were used as additives to silica-based sols prepared separately in acidic and alkaline conditions. Characterization test results showed that coating could be obtained on fiber surfaces with the all applied treatments. The rigidity of the fabric caused by silica sols can be reduced slightly by adding both cationic and nonionic softeners. The applied coating processes slightly increased the air permeability. It was concluded that decreasing the rigidity of the silica coatings could improve the abrasion and tear strength of the denim fabrics to a certain level.

摘要

采用溶胶-凝胶法制备二氧化硅涂层，对日常生活中最常用的棉牛仔布进行表面改性. 以阳离子型和非离子型柔软剂为添加剂，分别在酸性和碱性条件下制备了硅基溶胶. 表征试验结果表明，经各种处理后，纤维表面均能获得涂层. 加入阳离子型和非离子型柔软剂，可使硅溶胶引起的织物硬度略有降低. 应用的涂层工艺略微增加了透气性. 结果表明，降低二氧化硅涂层的硬度可以在一定程度上提高牛仔布的耐磨性和撕裂强度.
