“…At MLR 1:30 the higher colour strength was obtained might be due to that quantity of liquor was optimum for the complete dissolution of dye which leads maximum absorption on the fabric. However, MLR less than that did not result in uniform absorption of dye from the dyeing bath on to the fabric (Bhandari et al , 2018).…”

Purpose This paper aims to focus on the optimisation of dyeing recipe for dyeing of silk fabric with semisynthetic azo dyes synthesised by chemical modification of areca nut extract. Design/methodology/approach The response surface model (Box–Behnken design) was used to establish the relation between the parameters of dyeing such as time, temperature and material to liquor ratio. Their output responses in terms of colour strength (K/S values) are reported. Their relationship was tested for predictability and the experimental values and found to match closely, which confirms the model suitability. Findings Dyed fabrics were tested for their fastness properties such as wash, rub and lightfastness. The results of the fastness tests indicate that modified dyes have good dyeability towards silk fabric. The dyed fabrics were also tested for ultraviolet protection factor and antimicrobial activity, which showed very promising results. Originality/value Banned amine testing was done, which confirms the absence of banned amine in synthesised dyes, which indicates the potential of its sustainability. Also, such an approach of modification of natural dyes as semi-synthetic dyes can be surely considered to be a step towards its widespread acceptability and further commercialisation.

Natural dyeing of cotton is commonly associated with the use of metallic mordants, which are related to harmful effects on the environment and human health. For this reason, more environmentally sustainable processes should be investigated. In this work, cotton was cationized with ovalbumin by cross-linking in order to improve its dyeing with natural cochineal dye. Different pretreatments with chitosan, synthetic cationizer, and metal mordants were also carried out at different dyeing pH values. The best dyeing results were obtained at pH 3 at 55℃ on fiber pretreated by padding with a liquor concentration of 150 g L−1 ovalbumin and 90 g L−1 cross-linker. This cationization of ovalbumin by cross-linking was confirmed by Fourier transform infrared spectroscopy, energy dispersive X-ray spectroscopy, changes in the isoelectric point of the fabrics, and scanning electron microscopy. The kinetic study showed that the pseudo second-order model best represented the experimental data, indicating that the dyeing can be controlled by the chemisorption process. The equilibrium data were easily adjusted by the Langmuir model, indicating the formation of a dye monolayer in the cationized cotton. The thermodynamic study indicated that dye adsorption was spontaneous and exothermic. The cationized fabric with ovalbumin presented low wash fastness, good light fastness, and increase in tensile strength and crease recovery, with a decrease of hydrophilicity when compared with other treatments. Thus, ovalbumin is a viable and eco-friendly alternative in the dyeing of cotton with cochineal.
