متن کاملA Critical Comparison of Methods for the Analysis of Indigo in Dyeing Liquors and Effluents
Indigo is one of the most important dyes in the textile industry. The control of the indigo concentration in dyeing liquors and effluents is an important tool to ensure the reproducibility of the dyed fabrics and also to establish the efficiency of the wastewater treatment. In this work, three analytical methods were studied and validated with the aim to select a reliable, fast and automated me...
متن کاملSustainable Dyeing of Denim Using Indigo Dye Recovered with Polyvinylidene Difluoride Ultrafiltration Membranes
Indigo is one of the most consumed dyes in the textile sector, as it is widely used for the dyeing of denim clothes. About 15% of indigo used in the dyeing process is discharged to the wastewater treatment plants or sometimes into rivers, in countries where regulations are not strictly applied. In this work, real effluents that contained indigo dye were treated by means of 4 different ultrafilt...
متن کاملNano Clay as New Tool for Discoloration of Deyed Denim Garmnet with Indigo
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 fabri...
