decorate cloth. Although evidence of this art has been documented in many parts of the world, probably its origin is in the Island of Java, Indonesia. The word batik is derived from the Indonesian word ambatik, which means a cloth with little dots. Batik involves brushing or drawing molten wax onto designated areas of a cloth so that those areas can then resist coloration. Next, the cloth is dy...

Traditional pre-treatments, dyeing, and finishing of textiles have high environmental impacts because the usage energy, water, chemicals, production effluent containing leftover harmful dyes chemicals. In this comprehensive review article, advances in applications ultrasound sustainable various types to reduce their are discussed advantages/disadvantages such processes outlined. The enhancement...

The objective of this project was to biologically renovate reactive dyebaths and reuse the high-salt containing mixture in the dyeing process. This approach accomplishes two goals: (a) elimination of the color from the plant effluent; and (b) reuse of the renovated process water and salts, thus leading to final wastewater volume reduction, and water, as well as salt conservation. Nine commercia...

The cohort of 768 workers who were actively employed for a minimum of 6 months and died was retrospectively followed from 1 January 1953 to 31 December 2000. There were 328 women and 440 men observed. Proportionate mortality ratios (PMRs) were calculated using the Minsk-city population mortality proportions to generate expected numbers. The significant excess of pancreatic cancer (PMR=366%; 95%...

In this work, the efficiency of a photo-electrochemical method to remove color in textile dyeing effluents is discussed. The decolorization of a synthetic effluent containing a bi-functional reactive dye was carried out by applying an electrochemical treatment at different intensities (2 A, 5 A and 10 A), followed by ultraviolet irradiation. The combination of both treatments was optimized. The...

Using nickel electrode as dyeing electrode, sodium carbonate fixing alkali and anodic region region, cotton fabric was electrochemically dyed by reactive blue X-BR under external DC power supply. By comparing the rate, fixation polarization curve evenness of two methods, it can be concluded that electrochemical effect on dye is far better than traditional method.

The aim of this study is to apply and compare statistical regression and an evolutionary fuzzy system to model color yield in the polyester high temperature (HT) dyeing as a function of disperse dyes concentration, temperature and time. The predictive power of the obtained models was evaluated by means of MSE value. It seems that for modeling cases such as the one considered in this study, the ...

Four imines, the condensation products of 2,4-dioxo-4-phenylbutanal with four primary amines, were condensed with mercapto acetic acid to obtain thiazolidinon-4-ones which on subsequent condensation with vanillin and isatin separately yielded eight thiazolidin-4-one derivatives. The chemical structures of the synthesized compounds were elucidated by elemental analysis, molecular weight determin...
