چکیده
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; some have no affinity to dyes. So dyeing depends on both fiber and dyes chemical properties. Before dyeing we have to consider this factor. The fiber reactive dyes are known as the best for cotton for its wide range of application and better fastness properties. And these dyes are characterized by its reactions between dye and fiber.

Removal of Reactive Dyes from Wastewater using Cyclodextrin Functionalized Polyacrylonitrile Nanofibrous Membranes
Electrospinning of nanofibers with cyclodextrin (CD) is attractive because the produced fibers can potentially increase the efficiency of nanofibrous membranes by facilitating the complex formation with organic compounds and high surface area of the nanofibers. In this work, polyacrylonitrile (PAN) nanofibers functionalized with β– cyclodextrin (βCD) during an electrospinning process were used ...

The large number of publications in the field of extraction, purification, modification, and process optimization of natural dyes and their application on textiles demonstrates the revival of natural dyes on textile coloration. The use of natural dyes is growing in popularity because of the quality of the natural dyestuff obtained, the environmental compatibility of the dyes and the substantial...
متن کاملAnthraquinone dyes for superhydrophobic cotton.
Water-repellent, self-cleaning and stain resistant textiles are of interest for industrial applications. Anthraquinone reactive dyes were covalently grafted onto cotton fabric surfaces obtaining bright colors with good wash-fastness properties and giving rise to breathable superhydrophobic textiles with self-cleaning properties.

Abstract: The need for more efficient power systems has prompted the use of a new technologies includes Flexible AC transmission system (FACTS) devices. FACTS devices provides new opportunity for controlling the line power flow and minimizing losses while maintaining the bus voltages within a permissible limit. In this thesis a new method is proposed for optimal placement and sizing of Thyristo...
متن کاملContact allergy to reactive dyes in footwear.
Reactive dyes have been used in the textile industry for the past 60 years; they colour fibres brightly and are highly wetfast. They consist of a direct colourant (an azo, anthraquinone or phthalocyanin derivative group) connected to a reactive group, which is capable of linking through covalent bonds to the amine or sulfhydryl groups of proteins (1). We report a case of a delayed contact hyper...
