The purpose of this study was to investigate the effect of the reactive dye structure and type of penetrant in ink formulation on paper ink-jet printing. Different type of papers, which have same grammage was printed upon with three commercial reactive dyes, CI Reactive Blue 49 Ink 1, 4, CI Reactive Blue 21 Ink 2, Ink 5 and CI Reactive Blue 19 Ink 3, Ink 6, which are based on different reactive...

From Xenorhabdus luminescens XE-87.3 four variants were isolated. One, which produced a red pigment and antibiotics, was luminescent, and could take up dye from culture media, was considered the primary form (XE-red). A pink-pigmented variant (XE-pink) differed from the primary form only in pigmentation and uptake of dye. Of the two other variants, one produced a yellow pigment and fewer antibi...

Newfangled vinylsulfone (VS) based fiberreactive dyes were synthesized and applied to mill desized, bleached and mercerized textile fabric (100% cotton). Padthermosol dyeing method was utilized due to less hazardous environmental affects and high dye fixation to optimize dyeing quality parameters i.e. salt concentration, pH, dyeing time and dyeing temperature. The pretreated and dyed cotton fab...

The Pseudomonas aeruginosa GSM3 isolated from dye contaminated soil was able to degrade Reactive Violet 5 completely as a sole source of carbon (300 mgL) within 20 h under static condition. The organism exhibited good decolorization ability in the pH ranges from 5.0 to 9.0 and temperature from 30 to 40C respectively. The optimum degradation was observed at 37C and pH 7. The maximum concentratio...

    Background & Aims of the Study: Textile wastewaters are very various in chemical qualities. In other words, these industries are one of the largest producing dyes compounds; therefore their treatment is so complex and difficult. The aim of this study was to evaluate the potential removal of Reactive Red 198 and Blue Reactive 19 from synthetic solution by Acaciatortilis shu...

In the present study the treatment efficiency of O3 and UV+O3 processes were compared for the oxidation of simulated dyebath effluent containing a mixture of a reactive dye (C.I. Reactive Blue 19) and various dye auxiliary chemicals. The color, COD and TOC removal rates were assessed for different processes. The effect of initial dye concentration and presence of sodium hydroxide and sodium car...
