A cleaner production of denim garment using one step treatment with amylase/cellulase/laccase

摘要

Denim garment is one of the most important and highly used textile clothing, regarding its exclusive features including color, versatile appearance and high strength that are widely used by young people. To create diversity in denim garment it is necessary to apply special techniques and new substances to respond the huge market demand. In this paper, bio-treatment process, using amylase, cellulase, laccase, and their combinations applied on denim garment to conduct one step bio-desizing and bio-washing producing old-look appearance garment is proposed and analyzed. The color changes of denim samples and the whiteness of the back and staining on the pocket was measured and the surface morphology of the samples were observed using Scanning Electron Microscope. The results indicated successful treatment regarding one step bio-desizing and enzymatic bio-washing using mixture of amylase and cellulase and laccase. The obtained color on the samples treated with the three enzymes has not been differed significantly with the bio-desized garment treated with cellulase or laccase and cellulase/laccase (cellulase and laccase).
