“…One of these methods includes the introduction of cationic groups such as thiol, amino, or ammonium groups onto cotton macromolecular chains, generally called "cationization of cotton", in order to enhance the interactions with anionic dyes [5]. The reactive dye could easily react with these nucleophilic groups at lower pH values which are substantially necessary for cellulose dyeing.…”

Cotton fabric was successfully modified by chitosan-poly(propylene imine) dendrimer hybrid (CS-PPI). Cationization of cotton was conformed through zeta potential test. The effects of grafting variables, CS-PPI concentration, pH, time, and temperature on grafting yield were investigated using both salt-free and conventional reactive dyeing processes. Optimal grafting parameters were found to be CS-PPI concentration of 20 % owf, pH 6, grafting reaction temperature of 50 o C, and time of 18 h. Color strength of dyed modified cotton was markedly enhanced in absence of electrolyte or alkali. Dye build-up of modified cotton in salt-free dyeing was higher than that of raw cotton dyed by conventional method. Moreover, the amount of dye fixed on modified cotton was markedly higher than that of virgin cotton. Wash, light, and rubbing fastness and mechanical properties of dyed modified cotton were satisfactory. The results clearly demonstrated high potential of CS-PPI hybrid as a promising bio-compatible compound for eco-benign modification and salt free reactive dyeing of cotton fabrics with satisfactory properties.

“…To solve this problem, a number of studies on cotton dyeing have been carried out to improve the dye uptake or achieve salt-free dyeing. Most research has focused on introducing cationic sites into the cotton fabrics for interactions with anionic dyes [2][3][4][5]. In addition, as the ever-growing demand for healthy living, antimicrobial activity, and antiultraviolet property of the cotton garments have attracted increasing attention, particularly to cotton underclothes, sport clothing, and light garments worn in the summer [6,7].…”

An amino-terminated hyperbranched polymer (HBP-NH 2 ), synthesized from methyl acrylate and diethylene triamine by polycondensation, was applied to treat cotton samples by a pad-dry-cure method. Physical properties, salt-free dyeability, antimicrobial activity, and antiultraviolet property of the treated cotton samples were tested. The crystallinity and mechanical properties, including breaking strength, breaking elongation, and Young's modulus of the treated cotton fibers, increased slightly in comparison with those of the untreated cotton fibers. The thermal stability and the moisture regain were also improved slightly. Dyed with direct dyes and reactive dyes in the absence of the electrolytes, the treated cotton fabric showed similar or higher color strength compared with the untreated cotton fabric in conventional dyeing. The treated cotton fabric can also be dyed with acid dyes effectively. In addition, the treated cotton fabric showed good antimicrobial activities against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). The study of the antiultraviolet properties of the treated cotton fabric indicated that the HBP-NH 2 contributed to the reduction of UV transmission and the increase of UPF.

“…The absorption property of this berberine compound shows the yellow shades in the visible range of 400-440 nm. In our previous work, 13 berberine was successfully applied to cellulose fibers, by providing anionic sites on the cellulose fibers through the reaction with synthesized anionic bridging agent and their antimicrobial ability was tested by the author. To apply this cationic berberine compound towards any fiber substrate, the anionic attraction sites are necessarily needed to impart electrostatic attraction forces.…”

Berberine, a natural cationic colorant was successfully employed onto nylon 66 fiber in this research. The effects of three important variables, namely pH, temperature, and liquor ratio were examined on the % exhaustion, color strengths, and color yields of the sample. It has been employed in antimicrobial finishing as a natural agent on nylon 66 due to its characteristics of cationic quaternary ammonium salt. Antimicrobial activity of the sample was studied against Staphylococcus aureus (ATCC 6538) and Klebsiella pneumoniae (ATCC 4352) according to test method KS K 0693-2001 and the corresponding berberine finished sample showed very effective antimicrobial functions showing about 99.9% of bacterial reduction against above-mentioned two bacteria. The maximum % exhaustion, color strengths, and color yields were obtained at 98 8C, alkaline condition (pH 11) and lower liquor ratio (20 : 1). An appropriate predictable empirical models were also developed using Excel solver function incorporating interaction effects of all variables to predict the % exhaustion, color strength(K/S), and the satisfactory results (R 2 > 0.99) were obtained.
