Ecological Sulphur Dyeing and Biotreatment for Cotton Fabric

Article Preview

Abstract:

Selected reducing agents were applied to cotton knitting dyeing with C.I. sulfur black 1, and followed by acid cellulase treatment. The K/S value, fuzz removal rate, sulphurs content of fabric and COD value of the residues was measured to evaluate the cellulase performance. The results show that minimum sulphur content detected when glucose was used as reducing agent, which exhibited maximum fuzz removal, whereas maximum sulphur content detected when sodium sulfide was used as reducing agent, which gave minimum fuzz removal. It is concludes that ecological sulfur black dyeing with sulphur-free reducing agent could decline the suphur content in the fabric and promote cellulase performance.
