Creative Designing of Fabric Patterns by Tie-Dyeing with Synthetic Dyes

Eco-friendly Dyeing of Viscose Fabric with Reactive Dyes

Water-soluble polymers have versatile applications but they are hardly used in wet processing of cellulosic substrates (cotton, viscose, jute, etc.), particularly in dyeing. In this paper, one such water-soluble polymer, polyacrylic acid has been synthesized, characterized and applied to viscose fabric in conjunction with various types of reactive dyes, namely triazinyl, vinyl sulphone, high ex...

Dyeing 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...

Dyeing with Disperse Dyes

Before the First World War, almost all dyes were applied from solution in an aqueous dyebath to substrates such as cotton, wool, silk and other natural fibres. However, the introduction of a man-made fibre, cellulose acetate, with its inherent hydrophobic nature, created a situation where very few of the available dyes had affinity for the new fibre. Water-soluble anionic dyes had little substa...

Dyeing of Indian wool with reactive dyes

Wool fibres have been chemically modified by reduction I chlorination under acidic pH Ipre-swelling in conc. formic acid prior to their dyeing with indigenous reactive dyes of different molecular configurations to enhance the reactive dye uptake on wool fibre substrate. The pretreatment processes are inexpensive, less harmful and less time consuming as against the use of imported special wool r...
