In this study, the Acid Black 1 dye containing effluent collected from a dyeing unit was examined with the alginate extracted from the marine brown algae, Sargassum sp. for its removal. Batch experiments were carried out using standard Jar test apparatus. Fourier Transform InfraRed (FT-IR) Spectroscopy and Scanning Electron Microscopy (SEM) techniques were used to characterize the raw algin...

Understanding the dyeing behaviors of reactive dyes onto cotton in non-aqueous media is helpful to facilitate development sustainable dyeing. Here, thermodynamic characteristics with liquid paraffin (LP) and decamethylcyclopentasiloxane (D5), were investigated compared those aqueous medium. The results showed that adsorption isotherms LP, D5, water accorded Freundlich model, indicating proceede...

The current study is aimed to utilize the microwave for isolation of colorant from neem bark and its application onto chemical & bio-mordanted cotton fabric. For the purpose, aqueous, acid and organic media have been employed to isolate the colorant and to make its application onto surface modified and bio-mordanted cotton fabric followed by microwave treatment up to 6min....

Pseudomonas putida strain SJ3, which possesses caprolactam-degrading ability, was isolated from dyeing industry wastewater in Daegu, Republic of Korea. Here, we describe the draft genome sequence and annotation of the strain. The 5,596,765-bp-long genome contains 4,293 protein-coding genes and 68 RNA genes with 61.70% G+C content.

Part 1 of this chapter covers the chemical development of sulfur dyes and the general principles of their application to cotton. Sulfur dye reduction and oxidation are compared with those of vat dyes. The effect of different chemicals on each part of the dyeing process is discussed with respect. to their cost, benefits and environmental impact.

A simple, one-pot method is presented whereby gold nanoparticles coated with a zwitterionic diblock copolymer are incorporated within single crystals of calcite. This may provide a versatile alternative to dyeing crystal with organic molecules and could be extended to create a series of new nanocomposite crystals with novel properties.

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...
