Low temperature bleaching and dyeing properties of modified cellulose fabrics with triazine derivative

Abstract

Abstract Cellulose fabrics were modified with triazine derivative containing multi-cationic groups, 2,4,6-tri [(2-hydroxy-3-trimethyl-ammonium)propyl]-1,3,5-triazine chloride (Tri-HTAC). Low temperature bleaching of modified cellulose fabrics with tetra acetyl ethylene diamine (TAED), tetra acetyl glycineurea (TAGU) or (N-[4-triethylammoniomethyl]-benzoyl) caprolactam chloride (TBCC) as H 2 O 2 activator was investigated. Bleaching properties and mechanisms of three activators were discussed. The dyeing properties and colorimetric data of the bleaching fabrics were investigated. The results show that the modified cellulose fabrics with Tri-HTAC could be bleached with hydrogen peroxide at low temperature, using activators. All whiteness indexes and wettabilities of modified fabrics under low temperature bleaching conditions were significantly higher than those of control samples. The exhaustion of the bleached modified fabrics was significant higher than that of unmodified cellulose fabric. Color degree of all bleaching fabrics with activators was also improved. The fastnesses of bleached fabrics were excellent. The quality of modified fabrics bleached under low temperature activator systems was improved. It has potential application in new composites and cleaner production of cellulose biomaterials.
