Applied Researches of Chitosan and Silicon Sol as Fixing Agent on Ramie
To improve the color fastness of the ramie fabric dyed with reactive dye, we researched the fixation effects of Chitosan biguanide hydrochloride (CGH), silicon sol and the fixing agent TR7234 on the ramie fabric. It was found that the mixture of CGH/silicon sol/TR7234 improved obviously the color fastness of the reactive dye on the fabric. The color fastness to dry rubbing increased by 1grade and the color stability to washing got the raise. Based on SEM and FTIR analysis, it was shown that the mixture of three agents formed a film on the surface of the fabric, and this film had the chemical bonds with some cellulose molecules.
