Removal of C.I. acid blue 29 from an aqueous solution by Aspergillus niger

Removal of C.I. Acid Blue 29 from an aqueous solution by biosorption on dead Aspergillus niger fungus was investigated. Pretreatment with sulfuric acid was most effective with a biosorption capacity of 13.82 mg/g biomass compared with 6.63 mg/g of living biomass. Batch pH, kinetic, and isotherm studies were conducted to evaluate the bioso..

Fuzzy neural network approach to classifying dyeing defects

Classification of seven kinds of dyeing defects is proposed using image processing and fuzzy neural network approaches. The defects include filling band in shade, dye and carrier spots, mist, oil stain, tailing, listing, and uneven dyeing on salvage. The fuzzy neural classification system is constructed by a fuzzy expert system with the n..

Effect of ultrasound on disperse dye particle size

The potential of ultrasound as a means of enhancing dyeing efficiency is evaluated. Changes in the particle sizes of a disperse dye dispersion with ultrasound irradiation are studied using the turbidity concept, and the effect of particle size on the exhaustion rate is also investigated. Ultrasound irradiation of a dye dispersion reduces ..

An utilisation of waste materials in dyeing process

Our increasing awareness of environmental protection has been driving us to ecological considerations. In the textile industry sparkling "green" concepts in the textile market fall into the mainstream efforts following the 'ecology' trend, which can thus merchandise the opportunity to tie in with Ecology. Campaigns and movements emphasisi..

Effect of chitosan on the photofading of fluorescent agents of a pyrazonline type

Chitin(poly(1,4)-2-acetylamino-2-deoxy-beta-D-glucan), which is abundantly obtained from the exoskeletons of arthropods, as well as its deacetylated derivative chitosan find increasing use in various areas. Extensive investigations have been undertaken on the application of chitosan in textile industries, such as surgical sutures, antimic..

New dyeing machine Technodye HT 'Rapid System' (Spanish) (Nueva maquina de tintura technodye HT "Rapid System")

The Spanish company Argelich have developed a new dyeing machine. One of the most important things about this new machine is that it is designed with the environment in mind. In designing it the company has tried to ensure that the machine reduces the amount of pollution that it causes to a minimum - hence there is less atmospheric contam..
