Prospects of Fabric Dyeing Using Biochromes
The enormous usage of synthetic dyes in various industries, chiefly textiles and paper industries, has posed a considerable health and environmental hazard. This dictates the need for amendment in the textile coloration technology by using natural origin pigments to replace the existing toxic, mutagenic and teratogenic dyes. Therefore, the scientists have recently focused their attention on app...
متن کاملA Comparative Study on Dyeing of Cotton and Silk Fabric Using Madder as a Natural Dye
Madder is considered the queen of the reds which is one of the oldest used natural dyes. In this study, madder was applied to cotton and silk fabrics by using mordants in various ways to investigate the coloring effects. Alum and copper sulphate were used as mordants not only before and after dyeing process but also during the process. The aqueous extract of the dye was applied on the scoured c...
متن کاملSalt-free dyeing of cotton fabric modified with prepared chitosan-poly propylene imine dendrimer using direct dyes
This study presents a novel method for eco-friendly dyeing of cotton fabrics with direct dyes. Cotton fabric modified with chitosan-poly propylene imines dendrimer CS-PPI, and its dyeing and fastness properties were investigated using three direct dyes. The impacts of important factors, i.e., CS-PPI concentration, dye concentration, dyeing time, dyeing temperature, and salt concentration were i...
متن کاملDyeing of Cotton Fabric with Natural Dyes Improved by Mordants and Plasma Treatment
Nowadays, there is a great tendency for eco-dyeing and finishing of textiles with natural products. several natural dyes have been used for dyeing of protein fibers but a low number have the ability to dye cotton fiber because of low affinity of cellulose to the natural dyes. In this study madder and weld natural colorants were used to dye cotton fabric premordanted with three metallic salt...
متن کاملSynthesis and Applications of Three Vinylsulfone Based Fiber-reactive azo Dyes for Dyeing Cotton Fabric
Newfangled vinylsulfone (VS) based fiberreactive dyes were synthesized and applied to mill desized, bleached and mercerized textile fabric (100% cotton). Padthermosol dyeing method was utilized due to less hazardous environmental affects and high dye fixation to optimize dyeing quality parameters i.e. salt concentration, pH, dyeing time and dyeing temperature. The pretreated and dyed cotton fab...
