“…The sequence of operations involved in conventional and salt-free dyeing processes are presented in Figure 9. In a similar study, the cationisation of cotton fabric on an industrial scale was done by an exhaust method using CHPTAC at a concentration of 40 g/L and 80 g/L followed by dyeing with three different dye types [155]. The results showed that salt-free and alkali-free reactive dyeing is possible in producing medium to extradark dye shades without affecting the dyeing time.…”

“…Despite the wide usage of reactive dyes for cotton dyeing, the major limitation is the requirement for a high concentration of salt for dye exhaustion. Depending on the dye structure, shade depth and dyeing method, approximately 0.6-0.8 kg of salt per kg of fibre is required [149,155] for dye fixation. Even with the required amount of salt, 100% exhaustion cannot be assured and only 65-70% of reactive dyes are exhausted [156].…”

“…Therefore, the achievement of salt-free reactive dyeing is now an important requirement for the cotton industry. Cationisation of cotton is an effective alternative way to eliminate the need for salt in the reactive dyeing process [155,157,158]. Researchers have made efforts to achieve salt-free reactive dyeing through the cationisation of cotton fabrics on an industrial scale using 3-chloro-2-hydroxypropyl tri-methyl ammonium chloride (CHPTAC) as a cationic agent by an exhaust method followed by salt-free reactive dyeing with ultradeep jet black dye of shade 9.95% using a combination of the dyes Black GDNN-8.2% and Navy Blue-1.75%.…”

Cotton is the most significant natural fibre and has been a preferred choice of the textile industry and consumers since the industrial revolution began. The share of man-made fibres, both regenerated and synthetic fibres, has grown considerably in recent times but cotton production has also been on the rise and accounts for about half of the fibres used for apparel and textile goods. To cotton's advantage, the premium attached to the presence of cotton fibre and the general positive consumer perception is well established, however, compared to commodity manmade fibres and high performance fibres, cotton has limitations in terms of its mechanical properties but can help to overcome moisture management issues that arise with performance apparel during active wear. This issue of Textile Progress aims to: i. Report on advances in cotton cultivation and processing as well as improvements to conventional cotton cultivation and ginning. The processing of cotton in the textile industry from fibre to finished fabric, cotton and its blends, and their applications in technical textiles are also covered. ii. Explore the economic impact of cotton in different parts of the world including an overview of global cotton trade. iii. Examine the environmental perception of cotton fibre and efforts in organic and genetically-modified (GM) cotton production. The topic of naturally-coloured cotton, post-consumer waste is covered and the environmental impacts of cotton cultivation and processing are discussed. Hazardous effects of cultivation, such as the extensive use of pesticides, insecticides and irrigation with fresh water, and consequences of the use of GM cotton and cotton fibres in general on the climate are summarised and the effects of cotton processing on workers are addressed. The potential hazards during cotton cultivation, processing and use are also included. iv. Examine how the properties of cotton textiles can be enhanced, for example, by improving wrinkle recovery and reducing the flammability of cotton fibre.

“…Reactive dye such as DR36 and DV30 possesses prominent properties for their stabilities (Malade & Deshannavar 2018) and high level of washing fastness (Nallathambi & Venkateshwarapuram Rengaswami 2017). Nasuha et al (2016) have studied decolorization of reactive black 5 using Fenton-like.…”

Reactive dye has generally been used in woven cotton fabric dyeing industries. Some treatments of several reactive dyes may produce more toxicity than the original dyes. The objectives of this study were to find the optimal condition on dye degradation efficiency of commercial reactive red dye 36 (DR36) and reactive violet dye 30 (DV30) using Fenton-like reaction, and to determine acute toxicity by static bioassay method under the optimal condition. The experiment was designed by Box Behnken Design (BBD), in which an initial pH, catalyst dosage and initial concentration of H2O2 were considered as independent variables. The results showed that only an initial pH solution was the principal parameter which influenced decolorization of the reactive dyes. Other factors were much less significant. The optimal conditions were found to be given by pH 3, 1 g/L of catalyst dosage, 27.63 mM of concentration of H2O2 for DR36, and pH 3, 1.35 g/L of catalyst dosage, 45 mM of concentration of H2O2 for DV30. Ninety percent of both decolorization were achieved in 30 min. Acute toxicity tests of the treated solutions using freshwater fairy shrimps (Streptocephalus sirindhornae) revealed that the shrimps survived longer than 24 h, indicating that the treated solutions were not acutely toxic. The average leaked iron, ADMI value and total organic carbon were found to be less than 10 ppm, 5 ADMI and 9.17 ppm respectively, in the treated samples. This research demonstrated an efficient method for decolorization of the reactive dyes with low acute toxicity.

“…The process is primarily to attach the cationic compounds on cotton fabrics by chemical binding or physical adsorption for enhancing the substantively between anionic dye and cotton [25][26][27]. Such treated cotton would be dyeable with acid dyes under neutral or mildly acidic conditions in the absence of electrolyte in the dyebath [28,29]. In this research, the utilization of nanocomposite in the textile fields is examined by preparation and deposition of the Cs, Cs/Ag NPs and Cs/Ag NPs/ clay nanocompoites.…”

A CTUALLY, the present current work addresses an innovative approach for benign enhancement of dyeing of cotton fabrics assisted with nanocomposite based on chitosan (Cs), silver nanoparticles (Ag NPs) and clay. The Cs/Ag NPs and Cs/Ag NPs/clay nanocomposites were prepared using UV irradiation and applied on the cotton fabrics by paddry-curing method. The blank and treated cotton fabrics were dyed with C.I. Acid Orange 74. The Dye exhaustion, colorimetric analysis as well as fastness properties of the treated fabrics was evaluated. The obtained data proves that the nanocomposite of Cs/Ag NPs/clay is a promising mixture for durable dyeing for cotton fabrics.
