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...

Now-a-days sustainability is a crucial issue in denim washing. This research initiative performed aiming to resolve the crisis of washing by process optimization technique which highlights reduction water, chemical and time as well costing garments. In this work, administered reducing several wash & application baths into single bath confirming without alteration physical properties color fastn...

There is an increasing demand for air-dry performance of fluorocarbon finished materials. Thus, dyeing with different types of reactive, mono, bi, and multi-functional, dyes was evaluated as a novel treatment to create correct surface interface to maintain fluorocarbon performance without ironing or tumble drying. The effects of pre-treatment on fluorocarbon finishing of cotton fabric, a cellul...

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...

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...
