The white alpaca fibre was obtained from the company Inka Tops S.A. The mordants used were: alum (KAl(SO4)2·12H2O) at 20% and iron(II) sulphate (FeSO4) at 3%. Prior to dyeing, a pre-mordanting process was carried out (86°C for 30 min), and dyeing was performed through thermal treatment at 70 and 86°C (30 and 60 min). The CIELab [L*, a*, b*, chroma (C*) and hue (h°)] coordinates and reflectance were evaluated using a spectrometer; textile characteristics were assessed with OFDA (optical fibre diameter analyser) 2000; chemical bands were analysed with an FTIR-attenuated total reflectance (ATR) spectrophotometer, and colour fastness (light, washing, and rubbing) was evaluated using international American Association of Textile Chemists and Colorists (AATCC) standards. The results showed that luminosity (L*) significantly decreased after dyeing and pre-mordanting with KAl(SO4)2·12H2O (81.47) and FeSO4 (70.47). Additionally, the b* value and C* value significantly increased at higher temperature and longer dyeing time, resulting in slightly different shades and hues in each treatment. The coefficient of variation (CV) and curvature index (CU) presented significant differences, with CU increasing at 86°C/60 min with FeSO4. Colour fastness to washing and rubbing showed acceptable values on the greyscale. In conclusion, the mordants used had a significant effect on colour variation, textile characteristics, colour fastness, and FTIR spectrum. The most intense shades were observed in fibres pre-mordanted with FeSO4 (dull yellow-green) and in dyeing without mordant (yellow).","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 1","pages":"54-62"},"PeriodicalIF":2.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140074259","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}

Researchers have explored alternative approaches to address this issue, such as using natural dyes, supercritical fluids and so forth. In addition to environment-friendly approaches, reducing the number of experiments in studies, accurate production straightaway and using artificial intelligence (AI), one of the technologies of the present and the future that will provide significant support. Reaching clearer results with AI technology will not necessarily contribute to environment-friendly technologies. However, AI techniques, including artificial neural networks (ANNs) and adaptive neuro fuzzy interface system (ANFIS) were employed to predict the colour strength (K/S) of the dyed fabric based on process parameters. A comprehensive experimental design involving pressure, temperature, and time variations was conducted, and the results were analysed using multi-factor analysis of variance (MANOVA). The study demonstrates that supercritical carbon dioxide (scCO2) dyeing with madder on polyester fabric is a promising and environmentally friendly approach. Additionally, the optimised ANN and ANFIS models, aided by genetic algorithms (GAs), exhibit high predictive accuracy (less than 3%), providing insights into the impact of process parameters on colour strength. This research underscores the potential of AI-driven automation in textile dyeing, offering solutions for dye formula prediction, colour matching, and defect detection, reducing the need for human intervention in these processes.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 1","pages":"44-53"},"PeriodicalIF":2.0,"publicationDate":"2024-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140026159","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 contribution is the first to optimise the ultrasound-assisted extraction of purple basil by response surface methodology in terms of maximum total monomeric anthocyanin (TMA) content and pH-dependent increase in green intensity (IGI) using a three-level, three-factor Box–Behnken design. The latter was considered as a measure of the pH-indicator ability of the extracts. The independent variables were ethanol concentration, solvent/solid ratio, and extraction time for two types of solvents [aqueous ethanol with 0.1% (v/v) acetic acid (Ac) or hydrochloric acid]. Optimum conditions were determined for single and combined responses. The extracts were further characterised according to total phenolic content (TPC), percentage polymeric colour (PPC), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) antioxidant, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities. All models explained more than 93% of the variability. The combined response model for the Ac-acidified system gave more favourable optimal conditions [55.25% (v/v) ethanol, 30 mL/g solvent/solid ratio and 39.24 min] regarding lower ethanol consumption and shorter times. Validation experiments verified the model successfully predicted the responses.

The results showed that disperse dye carrier dyeing could significantly improve the dyeing depth of EVA foam. Addition of carrier and prolongation of dyeing time could significantly improve the colour strength (K/S) values and dye penetration. However, the increase of the dosage of dyes and the concentration of the carrier could lead to a serious decrease of the colour fastness to ageing of EVA. The colour fastness to ageing of EVA could be obviously improved by film forming on the surface.

The presence of flavonoid-based compounds in the dye extract was verified using liquid chromatography–mass spectrometry, Fourier transform-infrared spectroscopy, and ultraviolet-visible techniques. Moreover, alum mordant was also utilised in the silk dyeing process to compare the efficiency of bio and metallic mordanting agents. Experiment outcomes revealed that the chitosan mordanted-dyed silk sustained adequate fastness after being tested by washing, light, wet-rubbing, and dry-rubbing. In addition, superb bacterial inhibition percentages of 89% and 76% against Escherichia coli and Staphylococcus aureus, individually, were accomplished. Furthermore, the ultraviolet-protective behaviour of this silk sample was demonstrated with a 50+ ultraviolet protection factor and low-grade ultraviolet transmittance.

Currently, there are many textile printing techniques; however, the limitations and selectivity of these techniques still keep the printing method of rotary screen printing the most important and used among them. One of the advantages of rotary printing is its excellent application versatility, which can be used for any fabric and non-wovens, fibre, or mixtures, with high production speed, quality, colour fastness, and definition. However, due to its high complexity, rotary printing requires great technical knowledge. Rotary printing requires specific application care depending on the fabric structure, fibrous composition, grammage, and type of intended effect. Regardless of the technique used, printed articles need to ensure that the colour remains attached to the substrate, either by direct dye–fibre or indirect pigment–binder–fibre bonding, to resist the conditions of use, that is, light, abrasion, stretching, and washing. The rise in recent publications reflects the search for economic and sustainable textile printing alternatives, focusing on screen printing variables. Based on this, this review aimed to present a comprehensive guide containing all the care and essential technical information for processes based on rotary printing.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"140 4","pages":"556-570"},"PeriodicalIF":2.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139644666","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, the primary amine group in the APADs significantly decreases the photostability of Mannich-type dyed silk fabrics. To reveal the structure–activity relationship and photofading mechanism of the APADs by Mannich-type dyeing, six pyrazolone-containing APADs with similar structures were designed and synthesised. Variation in amino electron density among the dye analogues was related to differences in colour fixation of the Mannich-dyed fabrics, as determined from the calculated Mulliken charge densities. Using mass spectrometry to monitor the photodecomposition of the dyed silk, it is demonstrated that the Mannich-type dyed silk fabrics undergo photooxidative fading, in contrast to the conventional acidic-type dyed fabrics that undergo photoreductive fading. Furthermore, it is shown that the Mannich-type dyed silk fabric has a higher light fastness than conventional acidic-type dyed fabrics using the same pyrazolone-containing APADs. Evaluation of dye dipole moment and Mannich-type dyeing shows that the APADs with increased dipole moments generally demonstrated increased light fastness.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"140 5","pages":"757-768"},"PeriodicalIF":2.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138518101","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}

Currently, deep learning methods have demonstrated exceptional performance in fabric defect detection tasks. However, their performance is greatly affected by the number of defect samples, which is a challenge to obtain during actual production. To address this issue, this article proposes an unsupervised anomaly detection method for fabric defects using image reconstruction networks. This method only requires defect-free samples for training. During the training phase, the model compresses defect-free samples to obtain a low-dimensional manifold and reconstruct them. During the inference phase, the method assesses whether a sample is defective by calculating the reconstruction error between the input and output images, and locates the defect region by computing the difference in various patches. Furthermore, since fabric contains rich texture features, with high correlation between neighbouring pixels, a structure similarity index measure combined with mean absolute error is introduced to evaluate the reconstruction error, which enhances the model's representation ability for defect-free samples. Additionally, considering the diverse texture backgrounds in fabric, a multiscale reconstruction module is designed to optimise the reconstruction effect. Experimental results demonstrate that compared with other related approaches, the proposed method achieves high accuracy (image-based area under the curve (AUC) up to 98.2% and pixel-based AUC up to 97.3%) on multiple datasets and has good generalisation ability for different fabric textures.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"140 6","pages":"827-842"},"PeriodicalIF":2.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138518102","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}
