The Application of Water-soluble and Reactive Chitosan on Tea Pigment Dyeing
A novel chitosan derivative, O-acrylamidomethyl-N -(2-hydroxy-3-trimethylammonium)propyl chitosan chloride (referred to here as NMA-HTCC) which can replace the conventional mordant in the tea dyeing was synthesized with Glycidyltrimethylammonium chloride (GTMAC), Nmethylolacrylamide (NMA) and Chitosan in this paper. Conditions of pH 7~8, and 8g/L with novel chitosan in pretreatment is optimum for tea-dyed fabric. The results of dyeing experiments show that the cotton treated with NMA-HTCC give better dyeing characters on K/S value and fastness compared with the results in the absence of novel chitosan or on dyeing in the presence of metal mordant.
