Si/Ti复合水溶胶的制备及其对直接染料的固色研究

A Study on the Preparation of Si/Ti Nanasols and Their Application for Fixing Direct Dyes

用GPTS和TTB制备了Si/Ti复合水溶胶,将溶胶-凝胶法应用于直接染料的固色处理,处理后染物的皂洗牢度、湿摩擦牢度和湿熨烫牢度均有明显提高。从K/S值来看,处理前的布样在经历数次皂洗时,K/S值逐渐降低,而处理后的布样在经历数次皂洗时,K/S值基本上都有一个先升后降的规律,其中第一次皂洗后的K/S值全部上升,这种增深作用会随着皂洗次数的增加而减弱并趋于稳定。

An aqueous Si/Ti sol was prepared from GPTS and TTB and used to fix direct dyes on cotton by the sol-gel process. The treated samples' soaping, wet rubbing and wet ironing fastnesses were all markedly improved over the untreated samples. K/S values of the un- the first soaping, all K/S values rose. This darkening effect increases with increased soapings, then abates and stabilizes.
