One of the NTC goals is to strengthen the nations textile and educational efforts by uniting diverse experts and resources in unique collaborative efforts. The union of a polymer chemist, a mechanical engineer (with a textile engineering undergraduate background), a polymer physicist, and a number of researchers in the textile and processing industries to work toward the solution to an importan...

Abstract--Textile dying industry effluents are highly toxic in nature and it contains a large number of complex metal dyes. Many dyes used in textile industries are stable to light and resistant to aerobic digestion. Thus removal of coloured waste from industrial dye effluent is a most perplexing problem to such industries and the environment. On the other hand fly ash is a major pollutant gene...

Sorption technique is one of the most effective methods for recovering precious metals from wastewater solutions; however, its main drawbacks of the traditional sorbents are the slow kinetics and relatively low sorption capacities. As a solution, thin sorbent fibers have been highlighted because they can lead to fast adsorption kinetics due to their high surface areas and numerous binding sites...

HPLC coupled simultaneously to NMR and MS is particularly suited to the identification of unknown polar, non-volatile compounds in complex environmental samples, i.e. to non-target analysis of such samples, if pollutants are present in the ppb range. Both methods give complementary structural information. Optimum information on unknowns is gained if both techniques are coupled on-line. This rev...

Ethanol production in a simultaneous saccharification and fermentation (SSF) process using waste textiles as feedstock was studied. The dissolution pretreatment of waste textiles in ortho-phosphoric acid resulted in at least 2 fold improvement in enzymatic hydrolysis rate and reducing sugar yield. The reducing sugars obtained from dyed or discolored waste textiles by cellulase hydrolysis demons...

Fluorocarbon contaminates such as perfluorooctane acid or perfluorooctane sulfonate can be found in waste water from several industrial branches, mostly related to the textile industry. The problem arises from textile finishing for oleophobic and hydrophobic properties where fluorocarbons are still without equivalent alternative. Fluorocarbons can be either release during the finishing process ...

Decolourisation of waste water has now become a major problem for the treatment plants in various industries. Many industries use synthetic dyes to colour their products such as textiles, rubber, paper, plastics, leather, cosmetic, food etc. Nearly 10-15% of synthetic textile dyes, used yearly are lost to waste streams and about 20% of these losses enter the environment through effluent from wa...
