Abstract
Chitosan and CA/BTCA were employed in order to induce crosslinking in the fiber for the improvement of wrinkle recovery of the cotton fabrics and the endowment of anti-microbial functions to the fabric. The treated fabrics were dyed by using reactive dyestuff and their dyeing behaviors were investigated. As a result, the fabric treated with chitosan only exhibited more dye-uptake amount than the untreated fabric, and the treated and untreated fabrics together showed excellent light-fastness and wash-fastness. In the cases that CA or BTCA was added to the chitosan, the CA-treated showed better dye-uptake and dyeing properties as light-fastness than the BTCA-treated. In conclusion, it is possible to maintain the dye-uptake level at reduced treatment cost when the CA is employed as a substitute cross-linking agent for BTCA.
