Discoloration of Denim Garment with color free effluent using montmorillonite based nano clay and enzymes: nano bio-treatment on Denim Garment
Journal of Cleaner Production, 2015Co-Authors: Ali Sadeghian Maryan, Majid Montazer, Rogheih DamerchelyAbstract:Abstract In this research, discoloration of indigo dyed Denim Garment along with color free effluent is introduced by using a combination of bio and nano-treatment. Indigo dyed Denim Garment were treated with amylase, cellulase, laccase and their combination with modified Montmorillonite based nano clay and mineral clay in the conventional washing machine. Adsorption of released indigo dye in the washing machine on the clay particles essentially open up new opportunity for possible reuse of washing effluent. The colorimetric properties of the treated Garments were measured and the color changes expressed in CIE L*a*b* system. The surfaces of the treated fabrics were studied by scanning electron microscope and energy dispersive X-ray analysis. UV-Vis, Raman and transmission electron microscopy were used to study the possible interaction between the Montmorillonite and indigo dye. The results revealed the possibility of using combination of laccase and Montmorillonite in Denim washing as a competitor process with conventional bio-washing with enzyme producing lower indigo staining on the Denim Garment.

One step synthesis of silver nanoparticles and discoloration of blue cotton Denim Garment in alkali media
Journal of Polymer Research, 2013Co-Authors: Ali Sadeghian Maryan, Majid Montazer, T. HarifiAbstract:In this study a simple green route was used for producing worn-look Denim Garments with antibacterial property. Silver nanoparticles were successfully synthesized on Denim fabrics by reducing silver nitrate using cellulosic chains of cotton, starch and/or glucose in alkali media. Glucose had the ability to reduce indigo dye and resulted in better control of particle size and stability. Transmission electron microscopy (TEM), dynamic light scattering (DLS) and UV–vis spectroscopy were employed to characterize the synthesized Ag nanoparticles. The treated Denim fabrics were also characterized by scanning electron microscopy (SEM), Raman spectroscopy and colorimetric measurements. The results indicated the successful synthesis of nano silver particles with average particle size of 30–40 nm on the indigo dyed cellulosic fabric along with Denim color reduction. Although the fabrics showed antibacterial activity against E. coli and S. aureus, a decrease in the antibacterial feature was observed in presence of glucose as a suitable nutrient for the growth of bacteria.
