Effect of TiO2 on Anti-felting Finishing of Wool Fabrics with an Alkoxysilane Hydrosol
Alkoxysilane/titanium composite hydrosol, which applied on wool fabric as a shrinkproof agent, was prepared by sol-gel technology with γglycidyloxypropyltrimethoxysilane (GPTMS) and tetrabutyl titanate (TTB) as precursors. The influence of titanium in this alkoxysilane sol was investigated by FT-IR and thermogravimetric analysis (TGA). There was no obvious difference, caused by the addition of low concentration of titanium, in FT-IR spectra. However, the temperature, corresponding to sol-gel transformation, was lowered from 61.7oC to 56.9oC. The results indicated that incorporation of titanium hydrosol in alkoxysilane sol could fasten the polycondensation and lower curing temperature in anti-felting finishing of wool fabrics accordingly.
