Vat dyeing of Wool and Cotton fabrics with Sepia Melanin

Dyeing Wool with Metal-free Dyes – The Use of Sodium Borohydride for the Application of Vat Dyes to Wool

Investigation on Ecological Parameters of Dyeing Organic Cotton Knitted Fabrics

In this study, the ecological parameters of the effluent obtained from dyeing of scoured and mercerised organic cotton single jersey fabrics with textile reactive dyes adopting exhaust dyeing method was investigated. The dyes used include regular (Navacron H and FN) reactive dyes and low impact (Remazol and Levafix) reactive dyes along with inorganic salt (sodium sulphate) and biosalt (trisodiu...

Dyeing Effects Of Bifunctional Reactive Dyes On Knitted Cotton Fabrics

Introduction: Several new bifunctional reactive dyes of the Sumifix Supra range that carry monochlorotriazine and sulphato ethyl sulphone reactive systems were developed and their dyeing performance studied. Suitable characteristic properties and fastness properties were examined over the knitted cotton fabrics. The dyes were characterized by spectral data and elemental analysis. The dyes struc...

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...

The Influence of Cationization on the Dyeing Performance of Cotton Fabrics with Direct Dyes

The effect of cationic modification of cotton fabrics, using cationic agent (Chromatech 9414) on direct dyeing characteristics was studied in this work. Cationization of cotton fabric at different conditions (pH, cationic agent concentration, temperature and time) was investigated and the optimum conditions were determined . Nitrogen content of cotton samples pretreated with cationic agent was ...
