This investigation focused on boron, a pivotal mineral resource for our nation, and aims to elucidate alterations in fabric properties, specifically about colour changes and pilling, after the utilisation of various washing detergents. Comparative analyses and assessments were conducted across three distinct washing cycles, employing three distinct detergents: a boron-infused washing detergent, a standard detergent conventionally utilised in textile trials, and a widely adopted commercial detergent. The investigation encompassed three diverse fabric constituents—cotton, polyester, and viscose—subjected to scrutiny in terms of fabric parameters subsequent to 1, 5, and 25 washing cycles. Following the laundering processes conducted at 40°C, evaluations were conducted concerning the pilling degree and colour alteration of the fabrics. Consumer perception regarding colour alterations, and subjective colour assessments was undertaken with a panel of 10 individuals. Furthermore, the research delved into the stain removal efficacy of the boron-infused washing detergent. To assess stain removal, all fabrics were intentionally stained with six diverse contaminants: ketchup, mayonnaise, coffee, sweetened coffee, tea, and sweetened tea. A post-washing evaluation of stain conditions was carried out subjectively by an assembled arbitration committee. Over the course of 25 washing cycles, it was observed that the boron-containing detergent notably diminished colour strength, particularly evident in polyester and cotton fabrics. Pilling outcomes indicated a decrease in pilling as the number of washing cycles increased. Boron-containing detergent, denoted as detergent B, consistently demonstrated commendable stain removal properties, particularly on cotton fabric.</p>","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 2","pages":"159-171"},"PeriodicalIF":2.0,"publicationDate":"2024-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cote.12766","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140831872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, there has been rapid development in electrochromic technology. However, current research predominantly focuses on traditional rigid electrochromic devices (ECDs), typically using conductive glass substrates such as indium tin oxide. These rigid colour-changing devices face significant challenges, including large thickness, low mechanical strength, and high cost, which hinder the advancement and commercialisation of electrochromic technology. With the rise of wearable devices and electronic skins, among other future technologies, flexible ECDs have garnered much attention due to their foldability, wearability, and even embeddability. They have emerged as a research hotspot in the field of electrochromism. As a further development direction of flexible ECDs, achieving stretchability poses higher difficulties as it requires maintaining high performance under large strains and even distortions. This article provides an overview of the latest advances in stretchable electrochromic devices (SECDs) from the perspectives of structural and material design. Regarding structural design, the ‘island-bridge’ structure, the ‘longitudinal wave’ structure, and core-shell structures are discussed. In terms of material design, the design schemes of substrate, conductive layer, electrochromic layer and electrolyte layer are mainly introduced, with particular emphasis on the introduction of gel electrolyte.

This innovative design not only overcomes the deficiencies of PET fibre but also enables it to be dyed using cationic dyes or disperse dyes under atmospheric pressure conditions. However, the investigation of the dyeing process of cationic dyes on Porel textiles remains relatively scarce. In this work, response surface methodology (RSM) was used to optimise the dyeing process of Porel fabrics with C.I. Basic Blue 162. The effects of dyeing temperature, dyeing time, and dye concentration on exhaustion percentage and colour strength (<i>K/S</i> value) were investigated using the Central Composite Design (CCD) method. The optimal dyeing process condition was as follows: a dyeing temperature of 96°C, a dyeing time of 51 min, a dye concentration of 3.6% owf, a dye solution pH value of 4–5, and a liquor ratio of 1:20. Under the optimal dyeing process conditions, the Porel fabrics achieved an exhaustion percentage of 96.2% and a <i>K/S</i> value of 36.0.

New approaches that support sustainable production instead of environmentally harmful processes are extensively researched in the literature. When considering substitution of chemical processes with environmentally friendly methods, one of the issues that comes to mind is enzymatic processes. It is noteworthy that in recent years, interesting and promising studies on the use of laccase enzymes in textile dyeing have been published in the literature. However, studies on enzymatic colouring are still very limited and sufficient success has not been achieved especially on polyamide. The aim of this study is to develop an environmentally friendly enzymatic dyeing method, which can be an alternative to dyeing polyamide knitted fabrics with 1:2 metal complex dyes according to the exhaustion method. For this purpose, various phenol and amine compounds, and their mixtures were used as precursor, and the colours that can be obtained by enzymatic colouring have been determined. In addition, optimisation of enzymatic colouring conditions (enzyme concentration, temperature and time) was carried out for the precursors that gave the best results in terms of colour and fastness. Furthermore, enzymatic dyeing was compared with conventional 1:2 metal complex dyeing in terms of technical and economic aspects. The reaction pathways in enzymatic coloration with laccase enzyme by using various precursors were also explained by Fourier-transform infrared (FTIR) analysis.</p>","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 1","pages":"94-116"},"PeriodicalIF":2.0,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140323506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, there are relatively few researches on multi-objective colour formulation problem, and the colour matching accuracy needs to be improved. In this research, a multi-objective evolutionary meta-heuristic method based on the Fast and Elitist Multi-objective Genetic Algorithm (NSGA-II) was proposed to predict the target colour recipes. The method used dye concentration as a variable and included three objective functions: (1) minimising the CMC (Colour Measurement Committee) colour difference between the formulation colour and the target colour, (2) minimising the metamerism index, and (3) minimising the cost of the formulation. The algorithm could obtain the Pareto optimal solution set after iteration. On this basis, the best combination of formulations was selected from the optimal solution set by combining the Expert Scoring Method (ESM), Entropy Weight Method (EWM) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). The prediction effect of the model was evaluated by taking cotton fabrics and reactive dyes actually used in plant as examples. The results showed that 87.5% of the formulations met the CMC colour difference value of no more than 1, the metamerism index of 90.0% of the formulations did not exceed 1, and the cost of 92.5% of the formulations was reduced relative to the maximum extent in the Pareto optimal solution set.
