“…It is also clear that the increment of K / S values was slower when dye concentration was over 55 g/L. As more Blue 222 molecules were fixed on the fibers, there were less available sites for further reactions, leading to a slow increasing trend of K / S values at higher dye concentration [3]. Compared with untreated cotton fabrics, the K / S values and dye fixation rates of dyed cationic fabrics were enhanced by 39.4% and 14.3% at the maximum values, respectively.…”

“…Cotton is one of the most widely used natural polymer fibers in textiles and is usually dyed with reactive dyes [1,2]. For reactive dyeing of cotton, electrostatic interaction between the dye and the fiber mainly determine the final color performance [3]. Large quantities of inorganic salts (NaCl or Na 2 SO 4 ) need to be added into dye bath to enhance the utilization of reactive dyes [4].…”

The Poly[Styrene-Butyl acrylate-(P-vinylbenzyl trimethyl ammonium chloride)] P(St-BA-VBT) nanospheres with N + (CH 3 ) 3 functional groups were successfully prepared and applied to modify cotton fabrics using a pad-dry process. The obtained cationic cotton fabrics were dyed with pad-steam dyeing with reactive dye. The results show that the appropriate concentration of nanospheres was 4 g/L. The sodium carbonate of 25 g/L and steaming time of 3 min were suitable for dyeing cationic cotton with 25 g/L of C.I. Reactive Blue 222. The color strength and dye fixation rates of dyed cationic cotton fabrics increased by 39.4% and 14.3% compared with untreated fabrics. Moreover, sodium carbonate and steaming time were reduced by 37.5% and 40%, respectively. The rubbing and washing fastness of dyed fabrics were equal or higher 3 and 4–5 grades, respectively. Scanning electron microscopy (SEM) images revealed that the P(St-BA-VBT) nanospheres randomly distributed and did not form a continuous film on the cationic cotton fiber surfaces. The X-ray photoelectron spectroscopy (XPS) analysis further demonstrated the presence of cationic nanospheres on the fiber surfaces. The cationic modification did not affect the breaking strength of cotton fabrics.

New disazo and polyazo ureido reactive dyes incorporating different reactive systems were synthesized and applied to cotton fabric by the exhaust dyeing method. Different factors affecting the dye ability and fastness properties of such dyes are investigated. Bis(monochlorotriazine) reactive dyes displayed higher primary exhaustion values compared to those obtained with bis(sulphatoethysulphone) and bis(monochlorotriazine/ sulphatoethysulphone) reactive dyes under different neutral exhaustion conditions. The results obtained indicate that the fixation efficiencies of these dyes were higher than those of dyes incorporating the bis(dichlorotriazine) reactive system. The results assessed for alkaline exhaust dyeing indicate that the bis(monochlorotriazine/sulphatoethylsulphone) dye was less sensitive to the variation in fixation temperatures than the other reactive dyes. The fastness properties of the ureido reactive dyes were fair to good.The improved dyeing performance of such type of ureido reactive dyes should lead to the design of reactive dyes with good application and fastness properties on cotton fabric, and provide practical solutions for low-salt dyeing. The present study of synthesis of disazo and polyazo ureido reactive dyes of high molecular structure, and its application to cotton fabric by the exhaust dyeing method is novel and could be applied in the industry.
