Effect of Antioxidant and SiO₂ Combination on Linen Fabrics

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

抗氧化剂在可见光和氧气的作用下可以有效地减少材料的颜色变化，通过一种创新的整理工艺，溶胶-凝胶技术，被应用到亚麻织物上. 抗氧化剂和硅溶胶的结合，使织物的颜色更稳定的光. 以TEOS(四乙基正硅酸盐)和GPTS[(3-缩水甘油氧基丙基)三甲氧基硅烷]为前驱体，与没食子酸和l-抗坏血酸水溶液相结合，得到硅溶胶. 通过扫描电镜分析发现，添加了抗氧化剂的硅溶胶溶液改变了亚麻纤维的表面形貌. 结果表明，没食子酸加硅溶胶溶液能有效地提高织物的耐光牢度. SiO2 结果表明，交联剂的加入使干凝胶成为亚麻织物的保护层.
