"Environmental pressure is pushing towards the ‘green’ alternatives to synthetic or petro-chemically derived products. Biopolymers are replacement materials suitable for different chemical processes. The surface modification of textile fibres using biopolymers is considered as the best route for modern textile treatments, to minimize the generation of wastewater containing salts, unfixed dye and other chemicals, which may affect the environment and human health. To avoid these problems, the pretreatment of cotton with biopolymers is a safe option in eco-friendly dyeing. In the present work, chitosan was selected for application on cotton textile for improving its dyeing efficiency with natural dye (onion skin). Chitosan is a versatile polycationic polysaccharide possessing hydroxyl and amino functional groups, which can easily be fabricated with desired functional properties. The chitosan treatment was standardized on the basis of dyeing properties, such as percent dye absorption, colour strength (K/S) and wash fastness. When the chitosan treatment was applied with optimized parameters, it was found that the chitosan treated onion skin dyed fabric showed higher dye absorption (66.17%), colour strength (16.52) and wash fastness rating than the alum treated dyed fabric. Thus, the chitosan treatment enhanced the dyeing properties of cotton fabric towards the application of natural dye (onion skin), without using any metallic salt. To conclude, the chitosan treatment is a safe and environmentally benign route to improve the natural dye absorption of cotton fabrics."

The importance of sulphur dyes are realized due to the fact that they offer an economical method of achieving dyeing of good color strength and acceptable fastness on cellulosic substrates. However, the main limitations associated with this class of dye are the lack of availability of bright colors and it’s fading on exposure to laundering with detergent and perborates/peroxides formulations. In order to meet the growing requirements of customers regarding the higher wash fastness, garment traders are in turn demanding their suppliers to achieve these properties against single and multiple washes. In this study, sulphur black 1 dyed cotton fabric has been aftertreated with Fixapret CP, Bayprotect Cl and CC (Choline Chloride) with various sequential combinations to improve the wash fastnesss of the dyed fabric against the aggressive ISO-1O5 CO9 washing system. Sequential application of Bayprotect Cl followed by CC was found to offer a significant improvement causing a 12% reduction in percentage colour loss relating to the untreated fabric, which was comparable to the independent application of Fixapret CP with minimum deleterious effects on the hue, chroma and tensile strength of the fabric.

A natural dye extracted from lac was applied to a silk fabric by the use of pad-dry technique under different conditions. The dyeing properties were evaluated by measuring K/S and CIELAB values. In addition, the different fastness properties were evaluated. The effect of dyes at different mordant concentration levels with respect to their colour strength was also studied. Silk fabrics dyed with lac extract showed a light pink shade, while those dyed with alum and stannous chloride pinkish-red colour. Silk substrates dyed with CuSO4 gave a purple red colour, while those dyed with FeSO4 had a reddish-gray colour. The fastness properties ranged from fair to good, while washing fastness was poor level.

The objective of this paper was to study the application of Monochlorotriazine-β-cyclodextrin (MCT-β-CD) on cotton fabric and its influence on dyeing and fastness properties of the hot-dyeing reactive dye (with MCT reactive group), Drimarene Red X-6BN, on cotton. The optimum curing condition for MCT-β-CD on cotton was investigated. MCT-β-CD treatment was found to be unaffected on the dyeing properties of the dye on cotton. The color fastness to washing of the dyed fabric was improved in the presence of MCT-β-CD, while the light fastness was unaffected.

Cotton fabric samples were printed with acacia catechu willd. using reactive-printing technique has been investigated. The effect of different factors, i.e. quantities of urea, thickening agent and Sodium bicarbonate has been studied. The printed goods were evaluated by measuring the K/S values and the overall fastness properties. The results show that the colour strength (K/S) value of recipe 3 was the best printed result, and the next good result was obtained in the order of recipe 2 and recipe 1. The colour fastness results were ranging between fair and good level.

Abstract In the textile sector, the utilization of synthetic dyes is environmentally unfriendly and has a very harmful impact on human health and the environment. Hence, natural dye is assumed to be a suitable alternative for sustainable textile manufacturing and colouration, but it remains challenging to prepare the dyes having high stability with textile fablric. Herein we have demonstrated the dyeing process for cotton fabric with natural dye extractions from turmeric (Curcuma longa L.) and tea (Camellia sinensis) in the presence of mordant. Subsequently, we have prepared copper and 2-methyl 8-hydroxyquinoline functionalized graphene oxide (GO) (CHG) trinary-composite as mordant to improve the stability and colour strength of naturally extracted dyes. The prepared trinary-composite was investigated using various techniques such as FTIR, XRD, UV, and TGA analysis. To evaluate the effect of CHG composite, it mixed with natural extracted dyes such as turmeric and tea dyes, converted to CHG functionalized turmeric and tea dyes (TuCHG and TeCHG) for the dyeing of cotton fabric. TuCHG and TeCHG dyed cotton fabrics exhibited superior colourfastness, wash fastness and rub fastness in comparison to only turmeric and tea dyes dyed cotton fabrics. TuCHG and TeCHG dyes also demonstrated decent antibacterial properties. The present study indicates the new aspect for prepared mordant to increase natural dye colour strength and stability. Thus, this process is a much safer, cost-effective and sustainable method for the application of natural dyes with enhanced substantively for cotton fabric.

This research work was concerned with the stability of cacao dye and the application of this dye for cotton fabric dyeing by two techniques, namely direct dyeing and mordanting. The optimal conditions for cotton direct dyeing with cacao dye were carried out at 100°C for 60 min. It was observed that with an increase in the dye concentration, the ultraviolet protection factor values ranged good for cotton fabric. The results confirmed that natural dye have potential applications for fabric dyeing and producing UV protective cotton fabric.

A study was conducted to observe the effect of sericin treatment on dye abilty of cotton fabric using natural dye. Different parameters for sericin treatment were optimized on the basis of maximum percent dye absorption and washing fastness. It was found that 0.5 % (w/v) sericin in the presence of 4% crosslinking agent and 1 % catalyst treated at 70ºC for 45 minutes followed by drying at 70ºC for 4 minutes and curing at 160ºC for 2 minutes increased affinity of selected natural dye i.e. manjistha towards cotton fabric. Dye uptake of sericin treated fabric increased from 19.5 % to 31.7 % after application of sericin using all the optimized variables

Cellulose solution was used for coating and it was prepared by dissolving pulp cellulose in Urea-Thiourea-NaOH-Water solvent system. Reactive Red 240 dye was used for dyeing the coated as well as control cotton fabric. The effect of cellulose coating on the dyeing properties of cotton fabric was studied by measuring K/S values of the coated substrate at various concentrations of cellulose and dye. K/S value decreased after coating cellulose on the surface of cotton fabric. The lightness of cotton fabric increased after cellulose coating. SEM micrographs revealed that coated cellulose was attached to cotton fibers. Tensile strength increased after cellulose coating.

In order to improve fastness of printing silk fabric with natural dyes, the influence of sinapic acid on printing of silk fabric with sorghum red was investigated in this work. The silk fabric was printed using guar gum as paste, sorghum red as natural dye, sinapic acid as auxiliaries. The appropriate steaming condition was the temperature 100°C, time 15min and saturated steam. The results showed that the light fastness and the wash fastness of the printed fabric were improved by the addition of sinapic acid. It is proposed that sinapic acid can be applied as effective fastness improver of natural dyes.
