This study presents a novel method for eco-friendly dyeing of cotton fabrics with direct dyes. Cotton fabric modified with chitosan-poly propylene imines dendrimer CS-PPI, and its dyeing and fastness properties were investigated using three direct dyes. The impacts of important factors, i.e., CS-PPI concentration, dye concentration, dyeing time, dyeing temperature, and salt concentration were i...

This study aims to extend color shade range of Rubia tinctorum L. (Dyer’s madder) natural dye on wool textiles via binary combination Al, Sn, Cr, Fe, Cu, Ni, Co, Zn mordants. Wool yarns were premordanted, dyed with 75.0%owf madder dye, and characterized for their strength, colorimetric parameters, fastness. Nature single metal cations substantially affected shades, fastness properties due diffe...

This paper presents the results of absorption spectra, fluorescence properties and the effect of solvents on UV-Vis spectra of dye quaternized 4-acetylamino-N-2-aminomethylpyridine-1,8-naphthalimide. The fluorescency of the dye was evaluated and its Stokes shift value was 6140 cm-1 in DMF. The solvatochromism behavior of the novel compound is investigated by studying its spectra in pure organic...

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

As the market demand for environmentally friendly synthetic leather products has increased, water-based manufacturing technology and product performance have made great progress. Along with explosive growth of coffee grounds generated by urban consumers in their daily lives, research on sustainable reuse gradually become a trend field. This study discusses method preparing that reuses is assess...

Abstract The color fastness to light of textile in the product standard is always tested by method 3 GB/T 8427, which determines endpoint exposure according discoloration blue wool sample. aging xenon lamp for resulted different sun times references required same level. As a result, difficulty testing increased, and test accuracy was also affected. In this paper, relationship between time servi...

The present work describes the synthesis of a series of four novel biologically active 2-amino-5-arylazothiazole disperse dyes containing the sulfa drug nucleus. The structures of the synthesized thiazole derivatives are confirmed using UV-spectrophotometry, infrared and nuclear magnetic resonance techniques and elemental analysis. The synthesized dyes are applied to polyester fabrics as disper...
