Article's abstract:

Until recently, discoloration of the denim garment has been carried out through various methods including mechanical, chemical, physical and enzymatic treatments. In this study, the nano clay was co-applied in bio stone washing of denim with cellulase to obtain denim garment with a new look and clear effluent. Acid and neutral cellulases along with nano clay were applied on the dyed denim fabric with indigo and the properties of the treated sample and the obtained effluent were evaluated. The color changes of the denim fabric were investigated using colorimetric methods. The surfaces of the treated samples and montmorillonite in effluent were observed using SEM and TEM respectively. According to the results, nano clay as new tool, along with cellulase is caused increase of the lightness and decrease of the back-staining, create a new look and reduces the remained color in the effluent.
