Pure diacetate fabric is ink-jet printed using methods similar to those for polyesters. However, the K/S value of the printed fabric differs significantly from that of polyester, hindering the applications of this biodegradable acetate fabric. This article investigated ink-jet printing methods for diacetate fabric with steaming fixation and baking fixation methods. Three pre-treatment methods were chosen to size the diacetate fabric. The pre-treated acetate fabric was steamed or baked at different temperatures and times to determine the proper fixation temperature and time. Laser Raman mapping was used to probe the dyes diffusion in acetate fibre with different printing methods. The results showed that the baking fixation resulted in a higher colour yield for printed diacetate fabric compared to steaming fixation. The laser Raman mapping indicated that the baking method (200°C, 60 s) can more effectively promote the diffusion of disperse dyes into the fibres compared with steaming process (135°C, 30 min). Colour fastness, including washing soap fastness and rubbing fastness, for the printed diacetate fabric were all above level 4. Both printing methods could produce satisfactory printing products, which can help broaden the application prospects of diacetate fibre fabrics.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"142 4","pages":"502-510"},"PeriodicalIF":2.6,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148533332","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}

This paper introduces a saliency detection framework for silk surface defects, named EFRNet, which aims to overcome the limitations of existing technologies in handling such fabric imperfections. Firstly, a multilayered spatial domain edge perception method was designed. This method enhances the perception of defect edge details through edge-aware units and integrates these detailed features with high-level semantic information using cross-layer connection strategies, thereby achieving precise detection of defect edges. Secondly, a context-aware multilayer feature fusion technique is proposed, which includes attention-induced feature aggregation units and global context differential units, aimed at optimising feature selection, reducing background interference and emphasising the salient features of fabric defects through differential analysis. Experiments have demonstrated that EFRNet excels in improving the accuracy of small defect detection and local detail recognition. Compared with existing methods, it significantly enhances the quality of saliency maps, proving its effectiveness in enhancing the adaptability and precision of fabric defect detection.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"142 2","pages":"245-258"},"PeriodicalIF":2.2,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147649418","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}

The differentiation of the temperature-dependent dyeing/desorption behaviour of each of the six anionic compounds into two distinct, but interconnected, thermal regions, which corresponded to diffusion/desorption/adsorption undergoing a marked change at either 50, 60, or 70°C, was attributed to the broad, overlapping glass transition of the mobile amorphous and rigid amorphous phase components. As the experimentally observed diffusion/desorption/adsorption of each of the six types of anionic species adhered to a Williams–Landel–Ferry relationship, their thermally activated dyeing/desorption behaviour is governed by the thermally regulated relaxation times of the structural rearrangements occurring within the water-plasticised polyamide material. The plasticisation model of dye diffusion seems to offer a reasonable explanation of the observed temperature dependency of the diffusivity of the organic acid, each of the four acid dyes and sulphur dye within the different types of aliphatic polyamide substrate.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"142 2","pages":"296-326"},"PeriodicalIF":2.2,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cote.12825","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147653391","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}

Wood ash was extracted in an aqueous medium at 90°C and was used to prepare printing pastes at concentrations of 10%, 20% and 30% (w/v). Marigold dye was extracted from flowers, and cotton fabric was dyed with the extract. Discharge printing was optimised using response surface methodology (RSM), considering variables such as wood ash extract concentration, temperature and steaming time. The effects on discharging efficiency were analysed, and the process was statistically optimised. Elemental analysis of the wood ash extract revealed high concentrations of potassium, contributing to its strong alkaline nature (pH 10.2-11.4). RSM optimisation showed that the highest discharging efficiency was achieved with 20% wood ash extract at 100°C for 5 minutes. The discharging efficiency model was significant (P < 0.05), and validation experiments confirmed the model's accuracy. The predicted and experimental discharging efficiencies were closely aligned, demonstrating the effectiveness of the wood ash extract in discharge printing. The study presents a sustainable method for discharge printing using wood ash extract as an alkali on marigold-dyed cotton fabric. The optimised process achieves high discharging efficiency while reducing the environmental impact. This method highlights the potential of wood ash as a valuable resource in eco-friendly textile processing, promoting greener practices in the industry.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"142 2","pages":"236-244"},"PeriodicalIF":2.2,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147649419","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}

It was evident that the SC-CO2 medium enabled effective coloration of polyester at lower temperatures, ca. 100°C, and lower dyeing times in comparison with aqueous dyeing, and also reduced the necessity for water. By contrast, the comparable aqueous disperse dyeing of polyester needed to be at 120°C to achieve full coloration. Energy costs are important in textile dyeing and lowering the dyeing temperature is one approach to minimising energy consumption. In this study, we demonstrated for the first time the beneficial effect of a range of dyebath carriers/accelerants in lowering the SC-CO2 dyeing time and temperature for polyester, while still achieving effective coloration. The beneficial effect of salicylic acid carrier was similarly observed in the SC-CO2 dyeing of cellulose acetate, where the dyeing temperature could be reduced from 85 to 60°C and dyeing time similarly reduced. The recycling of textiles is an ongoing challenge for the textile industry. In this study, we have further explored the use of the SC-CO2 fluid as a medium for reprocessing of discarded dyed polyester and the potential reuse of the “locked-in” colourant. It was evident that the p-Vanillin accelerated the SC-CO2 colour mixing of the blue and yellow dyed polyester fabrics and could assist in producing new colours in “first life and second life” polyester at lower processing temperatures.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"142 2","pages":"196-207"},"PeriodicalIF":2.2,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cote.12821","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147653267","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}

Common methods such as applying skin fairness products and altering clothing ensembles to change skin tone perception are universal. However, there has been limited research on the effect of clothing colour on skin tone perception. In the current study, a real observation scenario was constructed and 22 plain-coloured sweatshirts in various hues, saturation and lightness were used to investigate the impact of clothing colour on facial skin fairness perception. In addition, clothing colour preference for young Chinese consumers was also explored. According to our results, clothing with lower lightness enhanced the appearance of fairer skin tones. Furthermore, participants showed a greater preference for clothing with low colourfulness and a blue tint. The results also indicated gender similarity in facial fairness perception but differences in clothing colour preference. Our experimental data were utilised to develop two models for predicting facial fairness perception and clothing colour preference. The prediction models may serve as an auxiliary tool for apparel designers and manufacturers, facilitating the provision of colour selection references tailored to consumers' skin tone characteristics and colour preferences.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"142 2","pages":"259-271"},"PeriodicalIF":2.2,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147649429","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}

As widely distributed polyphenolic compounds, PTs possess the unique capacity to perform dual roles in natural hair-dyeing systems: acting as direct dyes to impart colour and serving as mordants to enhance dye fixation and colour fastness. However, a systematic understanding of this integrated dual functionality and its potential synergistic effects remains limited. This review aims to bridge this knowledge gap through a critical and systematic assessment of the dual roles of PTs in natural hair dyeing. We delve into the molecular mechanisms governing PT–keratin interactions and their impact on direct dyeing performance. Furthermore, we systematically elucidate the coordination chemistry, bridging models and efficacy of PTs as mordants, including their inherent mordanting capabilities and synergistic effects with metal ions. This review also examines the sustainability of PT sources, the potential for utilising agro-forestry waste and green extraction strategies. Additionally, we evaluate formulation innovations designed to enhance application performance, such as synergistic co-formulation with other natural ingredients and the application of novel delivery systems. Finally, we discuss current challenges and future research directions, including the use of biotechnology and chemical modification to optimise PT properties. By integrating these key aspects, this review provides a comprehensive framework for understanding the complex behaviour of PTs in hair dyeing, offering theoretical foundations and guiding principles for the development of next-generation efficient, safe and sustainable natural hair-dyeing technologies.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"142 2","pages":"177-195"},"PeriodicalIF":2.2,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147653277","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}

In this context, dyeing was performed using conventional dyestuff and water ratios in a vacuum environment with 20 kPa pressure, and the leathers produced as the control group in non-vacuum conditions were compared in terms of dye exhaustion and colour measurements. Dye concentrations in wastewaters were measured spectrophotometrically and dye exhaustions were calculated. L*, a* and b* values, colour difference (ΔE) and colour intensity (K/S) in dyed leathers were determined. According to the results, it was determined that the dyestuff exhaustion increased with the vacuum application, and accordingly, the colour properties of the leather improved. The highest exhaustions were obtained from the water-free application and 25% dye-reduction and water-free trials used in the dyeing process, with a final uptake of 93.7%. As a result, by performing the dyeing process under vacuum conditions, the colour properties of the finished leathers could be improved, the amount of dyestuff in the wastewater could be reduced, and the water usage rates could be reduced.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"142 2","pages":"208-221"},"PeriodicalIF":2.2,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cote.12823","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147653310","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}
