Study on the effect of collagen color fixing agent on leather dyeing performance
A color fixing agent of collagen (PCDMC) was prepared by free radical polymerization water solution polymerization of methacryloyloxy ethyl trimethyl ammonium chloride (DMC) with collagen hydrolysate at the protection of nitrogen and using t-butylhydroperoxide (t-BHP) and sodium metabisulfite (SMBS) as redox initiator pair.The solid content and viscosity of color fixing agent was 37% and 300-600mPa·s,respectively.Then it was used in leather color fixing process and compared with commercial products DT-A622 and formic acid.The leather handle,dye uptake rate,K/S value and resistance to dry and wet fastness were as index to evaluate their color fixing effect.The results showed that PCDMC took on excellent softness and color,dye uptake rate was 97%,K/S value was 23,dry rub fastness and wet rub fastness were improved 0.5-1 grades.
