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...
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 کاملDyeing 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...
متن کاملDyeing Properties Using Natural Dyes from Rhubarb:
In this investigation dyeing of alginate fiber was carried out after cationic treatment of 11 EPTAC (2, 3-Epoxypropyl Trimethyl Ammonium Chloride). Optimum dyeing process and 12 parameter show good dyeing performance when alginate fiber dyed with rhubarb dye. In addition 13 to cationic treatment is taken into account for alginate fiber to improve fastness, color strength, 14 breaking strength. ...
متن کاملThe 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 ...
