ABSTRACT

Antioxidants, which are effective in reducing the color change in the material by the effect of visible light and oxygen, were applied to linen fabric by an innovative finishing process, sol-gel technique. Antioxidants and silica sols were combined to make the color of the fabric more stable to light. The silica sol was obtained using TEOS (tetraethyl ortosilicate) and GPTS [(3-glycidyloxypropyl)trimethoxysilane] as precursor and combined with aqueous solutions of gallic acid and L-ascorbic acid. When the images obtained by SEM analysis were examined, it was found that antioxidant added silica sol solutions have changed the surface morphology of the flax fibers. It has been found that gallic acid added silica sol solution was effective on improving the light fastness of the blue fabrics. Wear resistance results indicated that the addition of cross-linker in SiO₂ containing solution made xerogel a protective coat for linen fabrics.

摘要

抗氧化剂可通过可见光和氧气的作用有效减少材料的颜色变化，通过创新的整理工艺溶胶-凝胶技术应用于亚麻织物。抗氧化剂和硅溶胶相结合，使织物的颜色对光更稳定。使用 TEOS (原硅酸四乙酯) 和 GPTS [(3-缩水甘油氧基丙基) 三甲氧基硅烷] 作为前体并与没食子酸和 L-抗坏血酸的水溶液结合得到硅溶胶。当检查通过 SEM 分析获得的图像时，发现添加抗氧化剂的硅溶胶溶液改变了亚麻纤维的表面形态。研究发现，没食子酸添加的硅溶胶溶液对提高蓝色织物的耐晒牢度是有效的。₂含有溶液使干凝胶成为亚麻织物的保护层。
