Unlike traditional physical color models that struggle with the complex optical interactions in fibrous structures, our approach leverages neural networks' capacity to model non-linear relationships directly from experimental data. We designed a comprehensive grid-based color mixing framework using four strategically selected primary fibers (Grey, Cyan, Magenta, and Yellow), from which 66 distinct yarn samples were produced and characterized. Two specialized BPNN architectures were developed: one predicting blend ratios from spectral reflectance data, and another forecasting resultant CIELAB values from known blend ratios. The models were trained, validated, and tested using industry-standard metrics, achieving high accuracy with mean squared error values consistently below 0.03 for ratio prediction and color differences (ΔE) generally around 2.0 for color prediction. Practical validation involved producing yarns based on BPNN-predicted recipes, which demonstrated close visual and spectrophotometric agreement with target colors. Beyond addressing the limitations of conventional color theories, this bidirectional prediction framework offers significant practical implications for textile manufacturing, enabling both precise recipe formulation from target colors and accurate color forecasting from known recipes. This research advances textile coloration toward more sustainable, digitally-integrated production processes with color reproduction capabilities approaching modern digital color standards.</div></div>","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":"31 ","pages":"Article 101199"},"PeriodicalIF":7.9,"publicationDate":"2025-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144861114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leveraging the rich diversity of plant-derived phytochemicals, such as flavonoids, polyphenols, and alkaloids, this method offers a sustainable, cost-effective and eco-friendly route to nanoparticle production. However, despite its potential, key challenges remain: the incomplete characterization of plant extracts hampers reproducibility, control over NP morphology, and large-scale implementation. While many studies report successful NP synthesis, a precise understanding of the specialized metabolites involved is still lacking. Bridging this knowledge gap is crucial for optimizing NP properties and expanding their biomedical, catalytic, and industrial applications. This review critically examines the role of specialized plant metabolites in NP synthesis, detailing analytical techniques, such as LC-MS, FTIR, and NMR, for their characterization. Scalability remains a key challenge in plant-mediated nanoparticle synthesis, with reproducibility often limited by non-standardized extraction methods. Strategies such as protocol harmonization, the integration of advanced analytical tools, and the application of artificial intelligence (AI) can significantly enhance consistency and predictability. Recent publication trends show growing interest in green synthesis, particularly in applications across healthcare, food nanotechnology, and smart packaging.
