Textile industry comprises of dry mechanical and wet chemical processing,wet chemical process comprises of bleaches, dyeing , printing, & finishing. Dyeing is art of colouration to textiles.Dye get transferred to textile during dyeing. Dyeing operation is performed by the reaction between fiber and dyes. Some dyes are water soluble and some are water insoluble. Some fiber has affinity to dye; s...

The dyer has always been faced with choices regarding which dye to use and which application process to choose. In previous years, the cost of the dyeing process and the fastness of the dyeings obtained were prime considerations. Today these basic needs have been supplemented by the need for high productivity in the dyehouse together with an awareness of the environmental impact of the dyeing p...

Bleaching of organic cotton fabric can be done with hydrogen peroxide in which Catalase, a non-toxic, environmentally friendly biocatalyst is used to remove the residual H2O2 in a cost effective way for the better improvement of the cellulosic fabric properties. Enzyme treated organic cotton fabric was dyed with a natural dye obtained from orange corolla tube of Nyctanthes arbor-tristis flower ...

The sonochemical technique has already been proven as one of the best coating methods for stable functionalization of substrates over a wide range of applications. Here, we report for the first time on the simultaneous sonochemical dyeing and coating of textiles with antibacterial metal oxide (MO) nanoparticles. In this one-step process the antibacterial nanoparticles are synthesized in situ an...

Liposomes are lipid-water systems that can carry hydrophobic and hydrophilic materials because of their amphiphilic structures. Application of liposomes in dyeing and finishing textiles is a new technology based on targeting and slow release which can lead to dyeing at lower temperature along with energy savings and lower environmental impacts. In this research work, a practical method for dyei...

A series of azo disperse dyes based on aminothienochromene were synthesized. The fastness properties of the dyed samples were measured. Most of the dyed fabrics tested displayed excellent washing and perspiration fastness and moderate light fastness.

There is an increasing demand for air-dry performance of fluorocarbon finished materials. Thus, dyeing with different types of reactive, mono, bi, and multi-functional, dyes was evaluated as a novel treatment to create correct surface interface to maintain fluorocarbon performance without ironing or tumble drying. The effects of pre-treatment on fluorocarbon finishing of cotton fabric, a cellul...

A series of monoazo disperse dyes derived from arylazothienopyridazines were synthesized. Fastness properties of dyed polyester samples were measured. Most of the dyed fabrics tested displayed excellent washing and perspiration fastness and moderate light fastness. Finally, the biological activity of the synthesized dyes against Gram positive bacteria, Gram negative bacteria and yeast were eval...

Today’s generation is becoming more environmentally conscious and shifting towards sustainable fashion. Unfortunately, synthetic dye being dominantly used as they produce bright color are cheap but hazardous to health compared natural chemical free, biodegradable eco-friendly. Role of has been increased preservation traditional heritage also one the important development goals which every count...

The scientific community is continuously developing new methods for the recovery and purification of water, since precious resources our planet are increasingly scarce we must work to save clean waters. One used use adsorbent absorbent materials that remove from water those substances harmful environment nanoclays. In this work, effect a nanoclay, specifically Halloysite, adsorb reactive dyes h...
