“…This is because the QAS increases the dye fixation and less dye is wasted in the process. 25 The lightness values ( L ) and color coordinates ( a * b *) also depict that the color shade yielded from the single-step dyeing and finishing process was darker and deeper than the shade obtained from dyeing only. The lower value of the standard deviation shows that the dyed sample has high color uniformity, as color uniformity is inversely proportional to the standard deviation of K / S values.…”

In this investigation, a novel sustainable approach was employed to combine the dyeing and antimicrobial finishing steps for nylon fabric in a decamethylcyclopentasiloxane (D5) non-aqueous media dyeing system. Nylon fabric was dyed with acid dye and quaternary ammonium salt (QAS). Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride was employed in the dyebath as a fixing agent. The dyeing efficiency was assessed by measuring the color characteristics and colorfastness of the dyed fabric. The success of antibacterial treatment was analyzed by observing the reduction in bacteria colony forming units. These results showed that uniformly dyed samples with higher color strength than the aqueous bath and excellent colorfastness were obtained in the D5 non-aqueous media dyeing system. After five Launder-Ometer washing cycles, the treated samples still showed good antibacterial activity. These results showed that the acid dyeing and QAS finishing processes of nylon fabric can be carried out in a D5 solvent bath at the same time.

“…It is difficult to obtain dyed textiles with wash fastness ratings above 4 in the Grey Scale (Section 5.4.3). To overcome this issue, subsequent chemical treatments, based mainly on the use of metal salts or cationic active agents, are applied to improve fastness (Sharif et al, 2007). (ii) Cellulosic fibres and insolubilized dyes (azoic, vat, and sulphur): This class of dyes are insoluble in water.…”

“…Cationization has already been used on cotton fabric to improve its affinity toward different dye classes (El-Shishtawy and Nassar 2002;Frazer 2002;Hashem et al 2003;Subramanian Senthil Kannan et al 2006;Montazer et al 2007;Sharif et al 2007). Although its application to dye removal was initially proposed (Karnik 2002;Wang 2005), it was not further developed.…”

Wastewater effluents from textile industry mainly contain dyes used in the dyeing or printing of textiles yarns or fabrics. A lot of technologies can be adopted for dye removal from wastewaters, including biological treatments based on activated sludge, adsorption on activated carbon, or membrane processes. Nevertheless, none of these methods is performing toward all classes of dyes; treatment plants of great dimensions and difficult handling can be required, while cost can be prohibitive. In the present study, dye adsorption was performed on lowcost fibrous cellulose materials, submitted to a cationization process using a quaternary ammonium reagent. These materials were characterized by FTIR-ATR spectroscopy, while the treatment efficiency was investigated through exhaustion and kinetic adsorption tests toward anionic dyes, such as acid, direct, reactive, and a cationic dye. Comparisons were carried out between treated and untreated samples, and with activated carbon. Best results were obtained with cationized cotton, both in linters or ''tulle'' fabric form, showing good performance toward all the investigated dyes. Tests in continuous flow confirmed the good behavior of these materials, but tulle fabric was better as filtration medium for a lower pressure drop. Finally, regeneration tests by bleaching were carried out finding that regenerated material maintained good adsorption power.
