The effect of dyeing conditions on the dyeing properties was systematically analysed. At the same time, the colour fastness was evaluated and compared with that of a traditional water bath. Furthermore, the colour change properties and sensitivity of dyed fabrics at different pH values were investigated. Additionally, the potential application for real-time monitoring of environmental acidity and alkalinity was evaluated. The results showed that curcumin exhibited a higher K/S value on cotton fabrics in the D5 dyeing system than for the traditional water bath. Also, good dyeing build-up properties and colour fastness could be obtained at a pH of 8.0 and dyeing temperature of 70°C after 60 minutes. It was worth noting that the dyed fabrics exhibited an obvious colour change from yellow (450 nm) to red (520 nm) when the pH of the environment changed from 5.0 to 11.0. Meanwhile, excellent reversibility was obtained. As a result, when applied to different types of air atmosphere (hydrogen chloride or ammonia), an evident colour change from yellow to red was observed. Therefore, compared with traditional preparation methods, the technology can realise green preparation of colour-changing textiles. It also achieves the dual purpose of energy and emission reductions. This study suggests that the prepared pH sensor fabrics can be used as part of a smart colour change system for real-time pH monitoring of the environment.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"142 2","pages":"272-282"},"PeriodicalIF":2.2,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147653289","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 magnetite showed smaller and more homogeneous particle sizes, as observed in SLS and SEM analysis. Colorimetric analyses revealed evident changes in colour and brightness, especially for goethite, which exhibited the highest total colour variation (60.1) at 800°C compared with the samples not calcinated.

X-ray diffraction analysis confirms the formation of a substitutional solid solution with manganese replacing cobalt, associated with a shift in diffraction peaks to lower angles due to the larger ionic radius of manganese. As the manganese concentration increases (x = 0 to x = 0.6), lattice parameters and unit cell volumes increase, except at x = 0.5, which could be attributed to changes in cation distribution and lattice micro-strain. Raman spectroscopy shows shifts in the vibrational modes of metal–oxygen bonds, influenced by differences in atomic masses and bond strength constants between manganese and cobalt. Magnetic measurements indicate a decrease in coercive field, saturation magnetisation and remanence with increasing manganese content, due to weaker super-exchange interactions. Diffuse reflectance spectroscopy reveals low reflectance in the visible range due to electronic transitions in the metal ions. The substitution of manganese increases the band gap from 2.1 to 2.6 eV between x = 0.0 and x = 0.5, then decreases to 2.4 eV at x = 0.6. Colorimetric analysis shows significant variations in CIELab colorimetric coordinates, with lightness, chroma and hue changing with manganese content. Paints derived from these pigments, applied to cement, plaster and wood substrates, exhibit varied optical properties, demonstrating the influence of manganese on the optical characteristics of the pigments.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"142 2","pages":"283-295"},"PeriodicalIF":2.2,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147653336","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 study investigated horseradish peroxidase‐catalysed oxidation and coloration of four phenolic compounds on silk and cotton fabrics, incorporating polyethylene glycol (PEG) templates to improve dye uptake and stability. Dyeing performance was evaluated using colorimetric analysis, with maximum K/S values reaching 11.6 for cotton and 19.2 for silk (with PEG), representing an improvement of 36.5% and 9.7%, respectively, compared with non‐templated samples. Colour fastness to washing, rubbing and light was assessed according to ISO standards, showing that PEG‐treated fabrics exhibited ratings that were generally one to two grades higher, or at least equivalent, compared with non‐templated samples. Structural and morphological changes were examined by Fourier Transform–infrared spectroscopy, scanning electron microscopy and thermogravimetric analysis, while liquid chromatography–tandem mass spectrometry elucidated the polymerisation mechanism of the oxidised phenolic dyes. These results demonstrate that PEG‐templated enzymatic coloration can enhance colour intensity and fastness while maintaining sustainability, providing a viable pathway towards greener textile processing.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147889754","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}

With the discovery of synthetic dyes in 1856, the consumption of natural dyes declined sharply. However, the current focus on closed-loop systems, the circular economy and the promotion of sustainable industries aimed at reducing environmental impact (eg, The European Green Deal) has led to a renewed interest in plant-based dyes, along with an exploration of their applications, advantages and creative potential. In this study, we successfully integrated locally sourced plant-based dyes (flowers: golden tickseed, marigold, peony; berries: holly-leaved barberry, five-leaved ivy; leaves: ivy, birch, strawberry; and husks: English walnut, yellow onion) into screen-printed patterns. We focused on determining the photochemical and thermal stability of dyed products, complemented by live testing. Two types of commercially available tannins and three types of mordants on eight fabric types were used to investigate the colour gamut and creative possibilities of individual iterations. By applying the “intentional imperfection” design method, which results in dynamic and evolving patterns, the study embraced the inherent variability of natural colourants rather than forcing them into conventional, highly controlled manufacturing processes. The modulation of printing technique, incorporating deliberate imperfections, was explored to develop more stain-resistant and user-oriented designs open to subsequent modification through re-dyeing. This approach enhances the retention of the textile during the active stage of the product lifecycle and demonstrates its potential to contribute positively to the overall sustainability of the product.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 6","pages":"828-842"},"PeriodicalIF":2.2,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cote.70034","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145480054","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}

Colour design plays a pivotal role in influencing consumer behaviour, resource consumption and waste generation, yet it remains an underexplored area in sustainable design research and education. This article presents the development and peer review of the Sustainable Colour Design Strategies (SCDS) framework, a tool designed to guide designers, educators and industry stakeholders in making informed, sustainable colour decisions. The framework comprises eight strategies and 40 concrete actions, addressing key themes such as fostering a sustainable colour mindset, integrating colour circularity, embracing local identity and promoting bio-colour innovations. The SCDS framework was developed from a research-through-design approach, using a qualitative methodology combining systematic literature reviews to identify gaps, the analysis of 65 case studies to understand sustainable practices, stakeholder interviews and peer-review feedback to highlight the framework's potential to bridge the gap between theory and practice, emphasising its applicability in design education, industry and policymaking. By positioning designers as system thinkers, the framework supports interdisciplinary collaboration and innovation. This study contributes to advancing the discourse on colour sustainability, calling for its integration into design curricula and industry practices to promote a more sustainable, regenerative future for colour design.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 6","pages":"776-800"},"PeriodicalIF":2.2,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145480087","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}

However, developing eco-friendly dyeing processes and auxiliary products that maintain high chromatic quality remains a challenge. Natural indigo dye exemplifies this issue, as traditional industrial reduction methods using agents such as sodium dithionite are associated with significant environmental pollution. This study explored the application of fructose as a sustainable reducing agent for dyeing cotton fabrics with indigo extracted from the Indigofera tinctoria plant, adapting an artisanal process to industrial equipment. The most effective method involved a single-stage vat dyeing process conducted at 60°C for 60 minutes, using a 1-2-3 formulation. Results indicated that fructose emerges as an effective and environmentally friendly alternative in an industrial process compared with conventional toxic reducing agents. The study also evaluated the effect of different non-toxic auxiliary products and mordanting techniques. Pre-mordanted samples exhibited more saturated colours than post-mordanted; however, wash fastness results were lower. For example, gallnut used in the pre-mordanting process produced dark tones but showed noticeable colour change after washing, while post-mordanted samples achieved higher wash fastness. The integration of diverse auxiliaries in separate dyeing processes expanded the colour spectrum beyond the conventional blue typically associated with indigo dye, introducing a range of unique shades and hues. This study contributes to the recovery of traditional knowledge, incorporating more environmentally friendly products and adapting them to industrial equipment, while exploring a diverse chromatic palette. Such innovation supports fashion designers in creating distinctive and environmentally responsible collections.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 6","pages":"909-920"},"PeriodicalIF":2.2,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145479875","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}
