文摘

The effect of hydrolyzed collagen in the dyeing of cotton and leather was investigated. First of all, the compatibility of direct and anionic dyes with hydrolyzed collagen was studied at different pHs. Dyeing of cotton and leather was then carried out using various fractions of hydrolyzed collagen. The pH plays a very important role and the results indicate that there is synergistic effect of hydrolyzed collagen in the dyeing of leather. Even though the results are not promising in the case of cotton, there is a possibility to avoid the use of salt and to reuse the residual bath.
