While previous studies have focused on the dyeing procedures and mechanisms of cotton dyeing in non-aqueous medium, there has been limited research on colour matching between reactive dyes. This study investigates the matching performance of the representative dyes C.I. Reactive Red 195 and C.I. Reactive Blue 19 in a novel non-aqueous dyeing system, and compares their effectiveness to that of traditional aqueous dyeing systems. The building up power of reactive dyes in different dyeing bath was studied, as well as the influence of compounding ratio and fixing temperature on dyeing performance. The results reveal that reactive dyes exhibit better building up properties in non-aqueous medium compared to traditional water bath. The colour change and matching of the reactive dyes was different between non-aqueous medium and water bath, showing noticeable variations in fixation percentage. Notably, when the ratio between Reactive Red 195 and Reactive Blue 19 was 1:1, the absorption wavelength of the blend dye in the non-aqueous medium remained stable with increasing fixation temperature, while a redshift occurred in the water bath. Overall, the colour matching performance of reactive dyes in the less water dyeing system using a non-aqueous medium is impressive, suggesting significant potential for further development in sustainable dyeing technology.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 4","pages":"584-596"},"PeriodicalIF":2.0,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144589973","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 article, the effect of polyethylene glycol 400 (PEG-400) on the dyeing properties of cotton fabrics with high concentration reactive dyes in non-aqueous medium was studied. Initially, the effects of PEG-400 on colour strength (K/S) and colour fastness of dyed fabric with reactive dye are systematically discussed. In addition, the effect of PEG-400 on the hydrolysis properties of reactive dyes was analysed by high-performance liquid chromatography (HPLC). At the same time, the molecular interaction force between the dye and PEG-400 was analysed by ultraviolet-visible (UV-visible) spectroscopy. The results showed that when PEG-400 concentration was 3.0 g/L, K/S value of dyed fabric (5.0%, on weight of fabric, owf) was increased by 33.5%, and is much higher than dyed fabrics without PEG-400. HPLC and UV-visible analysis showed that the addition of PEG-400 effectively reduced the hydrolysis rate of dye II containing two vinyl sulfone reactive groups, which was converted from C.I. Reactive Black 5 containing contains diethylsulfone sulphate group. Its hydrolysis rate was reduced by 20.9%. PEG-400 also decreased the aggregation degree of high concentration reactive dye, and increased the solubility of reactive dye. This method has certain universality. Therefore, using PEG-400 as an additive is an effective way to improve the dye uptake of reactive dyes in non-aqueous medium dyeing system and realise cleaner production.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 4","pages":"572-583"},"PeriodicalIF":2.0,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144589968","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}

Current nano-pigment-based ink-jet applications provide unstable results for these properties, especially for synthetic and blended fabrics. This study focuses on cellulose-based blended fabrics as substrates to modify the wetting properties of fabrics through cationic and water-repellent treatments, to improve the coloration performance and colour fastness systematically. The study conducted analytical experiments to analyse the surface element composition, ion potential and surface morphology of the fabrics. Differences in printing colour and pattern performance were attributed to the behaviour of ink droplet spreading on the fabric surface and inside the fabric, including wetting time, colourant distribution, and ring shape. The results indicate that ink droplet spreading on fabrics significantly influences printing pattern sharpness, including edge clarity and colour intensity, which can be improved through surface modification, including cationic and water repellent treatment. The use of blended fabrics treated with 1% cationic modifier and 0.05% fluorine-containing water repellent resulted in effective suppression of droplet formation and significant enhancement of colour performance and fastness. Furthermore, as the ink droplet volume decreased from 5 to 1 μL, the coffee ring effect on the fabric treated with the water repellent agent gradually diminished, leading to improved printing sharpness during the printing process.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 4","pages":"559-571"},"PeriodicalIF":2.0,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144589765","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 the enzymatic dyeing of cotton and silk fabrics using six phenolic monomers (catechol, hydroquinone, 2-aminophenol, 4-aminophenol, 1,4-phenylenediamine and 2,5-diaminobenzenesulphonic acid) via oxidative polymerisation catalysed by horseradish peroxidase (HRP). The research explored the colouring mechanism, functional attributes and dyeability of the fabrics. The polymerisation mechanism of the polymer was elucidated through liquid chromatography–tandem mass spectrometry, while the functional and morphological characteristics of the dyed fabric were examined via Fourier transform–infrared spectroscopy, thermogravimetric analysis and scanning electron microscopy imaging. The dyed fabric underwent dyeability assessments, including colour depth analysis and various fastness tests. Under mild reaction conditions, nearly all the phenolic monomers successfully dyed both the silk and cotton fabrics using HRP. The dyed fabrics demonstrated enhanced thermal stability and dyeability. However, the cotton fabrics exhibited worse dyeability and fastness than the silk fabrics, with noticeable stains on their surfaces when dyed with certain phenols. These findings underscore the suitability of enzymatic oxidative dyeing for protein fibres over vegetable fibres, as well as the importance of tailoring enzymatic dyeing processes for vegetable fibres.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 4","pages":"547-558"},"PeriodicalIF":2.0,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144589687","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 trials were conducted to determine the optimal conditions for anthocyanin extraction using an ultrasonic water bath at temperatures of 25, 50 and 75°C. The ideal anthocyanin extraction occurred at 25°C using 100% acetone in an ultrasonic bath for 15 min at 35 kHz. Anthocyanin concentrations were evaluated using the pH differential method. The extracted anthocyanins were encapsulated through spray drying with maltodextrin as the encapsulating material. The encapsulation efficiency was 80.4 ± 0.20%, and the anthocyanin retention rate was 83.0 ± 0.76%. The coloured capsules were added to model systems with pH values of 4.50, 5.00, 5.50 and 6.00.

The results showed, that colour loss began on the fifth day and this was accelerated with higher temperatures and pH values. It was found that encapsulation significantly preserved the stability of the blue colour and the loss of the blue colour followed first-order reaction kinetics. The study showed that the blue colour of microcapsules was best preserved at pH 5.00 at 25°C.

Carotenoids are natural pigments that carry the disadvantage of sensitivity to temperature, light and the presence of enzymes and oxygen. Microencapsulation technology is widely used to protect these compounds against degradation, preserving their physicochemical characteristics. The research objective was to obtain the kinetics of carotenoid degradation of a microencapsulated extract of orange-fleshed sweet potato (Ipomoea batatas L.) and to establish its physicochemical properties. The sweet potato extract was obtained using ultrasound and then microencapsulated by spray drying using maltodextrin as the wall material. The microencapsulate obtained was subjected to degradation kinetics at 30, 40 and 50°C. Carotenoid quantification analysis, colour, rehydration properties, antioxidant capacity, Fourier-transform infrared (FTIR) and RAMAN spectroscopy and microstructural characterisation were performed on the microencapsulated carotenoids. From the kinetic analysis, the activation energy of the sweet potato extract was 16.31 kJ/mol while that of the microencapsulated sweet potato extract was 10.27 kJ/mol. Thus, it can be concluded that the microencapsulation process improved the stability of carotenoids subjected to thermal conditions. FTIR and RAMAN spectra confirmed the microencapsulation of the carotenoids. The microencapsulated powder showed a hygroscopicity of 0.22 g/100 g, wettability of 49 s and high solubility. The results obtained in the kinetics are a useful tool to predict losses during the process of heating the carotenoids from sweet potato, thus allowing improvement and selection of the products to which this powder can be applied, in either thermal or cold processes.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 4","pages":"518-530"},"PeriodicalIF":2.0,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144589880","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}

Many professional colourists find it challenging to develop a suitable colour recipe. The most difficult aspect is predicting which dye mix will result in the required shade on a given fabric. This study introduces an advanced alternative to the traditional colour-making method using an invertible neural network (INN) model. The INN model effectively addresses real-world inverse problems due to its bi-directional nature. In the forward phase, the model retrieves information about the colour recipe; in the backward phase, this information is combined with latent space data to predict the recipe. Furthermore, unsupervised data generated by the INN model is fed into clustering algorithms, such as K-means and the Gaussian mixture model (GMM), to obtain multiple recipes. The forward procedure was reintroduced with a predicted recipe to assess the efficacy of the proposed model. An analysis was then conducted on the colour differences between the anticipated and actual recipes. The colour differences, rounded to perceptually significant precision, from 30,000 samples with 50 centre points, are as follows: 1.4, 2.2, 2.5, 3.7, 1.2, and 2.1. These results indicate that the INN model and the GMM clustering approach together provide a highly accurate and efficient solution to automating the colour-matching process, offering a more precise and practical solution for the colour-manufacturing industry.","PeriodicalId":10502,"journal":{"name":"Coloration Technology","volume":"141 4","pages":"505-517"},"PeriodicalIF":2.0,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144589772","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}
