“…sizing additives act as binders to provide strength to the yarn during weaving. The removal of size reduces the binding between the fibres, and the fabric strength is affected after desizing [5,28]. TEGEWA rating 8-9 demonstrated the effective removal of size from the cloth; as can be seen, while the desized fabric displayed very light blue stains, the sized fabric revealed a dark violet.…”

Surfactant is one of the major consuming auxiliaries in textile processing. The rising demand for petroleum-based surfactants is in focus and it is tremendously utilized to fulfil the need for surfactants in textile industries. These petroleum-based surfactants are one of the major pollutants of textile wastewater. Many attempts have been made to replace this with low toxicity to make the process sustainable. The present investigation works on the same objective to replace the petroleum-based surfactant from desizing by using soapnut extract as a wetting agent. The process was optimised by using a modern statistical technique of Response Surface Methodology [RSM]. The initial designing was conducted using 10 g/l soapnut extract and 2% enzyme for 30 min at 75 °C and found satisfactory results. Additional desizing experiments were performed to optimize the process using RSM with weight loss as the primary outcome. An optimised desizing recipe provided by DOE numerical optimisation, viz., a concentration of 10 g/l soapnut extract and 2% enzyme at 75 °C for 40 min, was performed to validate. The findings demonstrate that optimum weight loss (6.58%) and desirable levels of absorbency (14 s), whiteness (73.52), yellowness (22.84 indices, bending length (2.1 cm), Flexural rigidity (98.13 mg.cm), while minimally affecting tensile strength (10.77). Enzymatic desizing with synthetic or soapnut-extracted wetting agents yields identical results and satisfies performance standards for industrial use. The Sustainable way of enzymatic desizing of cotton with bio-surfactant extracted from soapnut may be the green alternative to synthetic surfactant-based desizing.

“…Furthermore, the TAC industry has frequently implemented technologies and adopted processes that are locally efficient and lucrative but not environment-friendly (Valeur, 2013). Research studies, however, have demonstrated that environmentally friendly practices can boost a company's competitiveness and profitability (Hassan and Saifullah, 2023;Liu et al, 2017;Majumdar et al, 2022). The government has previously imposed lax environmental regulations on the TAC industry; however, this is becoming stringent with time and increasing environmental awareness.…”

Waste management in the textile and clothing (TAC) industry is a challenging issue due to high resource consumption and pollution generation. Therefore, the adoption of industrial symbiosis (IS) is the need of the hour for the TAC industry. However, the adoption of IS in emerging economies like India, Brazil, Bangladesh, etc. is limited due to various impediments. The present work aims to identify and analyse these barriers and develop mitigation strategies in the context of Indian TAC industry. Eighteen IS barriers have been identified and validated; and the interrelationships among them are studied by applying the ‘weighted influence non-linear gauge system (WINGS)’ method, which not only estimates the intensity of influence but also takes the self-strength of barriers into account. The results show that lack of trust amongst supply chain partners, lack of financial incentives from the government, lack of guidance from regularity bodies and industry associations and lack of consumer awareness are the most significant barriers. Additionally, the strategies to mitigate these barriers are developed based on a quadruple helix framework considering academia–-government–industry–society as the main actors. The findings of the study will be helpful for the TAC industry, policymakers and other concerned stakeholders in framing suitable strategies to improve the long-term waste management practices of the industry and to achieve sustainable development goals (SDGs).

“…Synthetic acid dyes are the most popular dyes for the coloration of wool fabrics, and a small portion of wool fibers are dyed with reactive dyes. Synthetic dyes provide wool fabric with vibrant colors, but many of the dyes used for wool fiber coloration could be toxic or harmful to the environment . The use of toxic dyes in textiles could be harmful to the wearer as they can migrate to the skin when a person sweats or the cloth becomes wet, causing skin sensitization or allergic effects. , Most of these dyes are not biodegradable, and their persistent color affects photosynthesis reactions that are necessary for the survival of aquatic plants and organisms.…”

Lignin is an abundant and complex biopolymer with inherent color but has only a few applications. It has the potential to replace synthetic acid dyes for the coloration of wool fibers in brown shades, as traditional dyeing with acid dyes produces toxic effluent needing costly treatment. In this work, the valorization of sulfonated lignin was explored by using it as a natural dye for the coloration of wool fabrics alone and with hydrogen peroxide (H 2 O 2 ). The dyed fabrics were characterized by reflectance and diffuse reflectance spectroscopies to assess the color yield and ultraviolet (UV) protection performance, respectively. The dyed fabrics exhibited reasonably good color yield and satisfactory colorfastness to washing (Grade 3/4), which improved to Grade 4 by the oxidation treatment with H 2 O 2 . The scanning electron microscopy (SEM) images show that when fabrics are dyed alone with lignin, deposition of lignin particles is visible on the fiber surface, but with hydrogen peroxide, no deposition of lignin is visible on the fiber surface, and the color strength of the fabric became almost double. The UV light transmission through the fabric decreased from 6.73 and 13.23% at 311 and 365 nm to 2.19 and 5.23%, respectively. The attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectra of the dyed fabrics showed increased absorption of lignin sulfonate by the fabric, suggesting depolymerization of lignin by H 2 O 2 to smaller macromolecules easing absorption into the wool fiber. Lignin sulfonate could be a cheap and sustainable alternative to harmful synthetic dyes for producing brown shades on wool fabric.
