Knowledge distillation for unsupervised defect detection of yarn-dyed fabric using the system DAERD: Dual attention embedded reconstruction distillation Coloration Technol. (IF 1.8) Pub Date : 2023-05-30 Hongwei Zhang, Shuaibo Liu, Shuai Lu, Le Yao, Pengfei Li
Detecting defects of yarn-dyed fabrics automatically in industrial scenarios can improve economic efficiency, but the scarcity of defect samples makes the task more challenging in the customised and small-batch production scenario. At present, most reconstruction-based methods have high requirements on the effect of reconstructing the defect area into the normal area, and the reconstruction performance

Insights into the dyeing using natural indigo (Indigofera tinctoria): Toward an environmentally friendly garment Coloration Technol. (IF 1.8) Pub Date : 2023-05-23 Luciana M. C. Silva, Patrícia M. dos S. Silva, Caroline S. Pagnan, Eliane Ayres
Currently, the use of natural indigo dye has been treated as an alternative to overcome the environmental pollution caused by synthetic indigo. Irrespective of the indigo dye source, it must be reduced to its soluble form by using reducing agents in a suitable alkaline environment. Herein, bio-sugars such as glucose or fructose were used for this purpose. The results revealed that when fructose was

Low-water-soluble reactive dyes for application in ultrafine polyamide/polyurethane synthetic leather Coloration Technol. (IF 1.8) Pub Date : 2023-05-23 Dexiang Li, Wei Ma, Bingtao Tang, Shufen Zhang
Ultrafine polyamide/polyurethane synthetic leather (UP/PSL), with a highly natural leather-like appearance and touch, is widely used in many leather commodities. Generally, acid dyes, which are mostly used for dyeing UP/PSL, exhibit poor colour fastness. While, reactive dyes are well-known for their good colour fastness. However, reactive dyes are not used to dye UP/PSL because they are water-soluble

Development of polycaprolactone-based electrospun pH-sensitive sensors as instant colorimetric indicators for food packaging Coloration Technol. (IF 1.8) Pub Date : 2023-05-20 Nihal Guclu, Sebnem Duzyer Gebizli, Mehmet Orhan
In the present study, polycaprolactone/polyethylene glycol (PCL/PEG) electrospun nanofibres with different anthocyanin (1%, 2%, 3%, and 5%) were fabricated for the instant measurement of pH, especially for applications—such as food freshness detection—where quick response is required. The solution, surface, chemical, thermal, wettability, mechanical, and release properties of the samples were evaluated

Coupling coloration of meta-aramid fabric utilising diazonium salts from weakly basic aromatic amines Coloration Technol. (IF 1.8) Pub Date : 2023-05-20 Hua Jiang, Jixian Song, Zhihua Cui, Weiguo Chen
Meta-aramid fibre exhibits poor dyeing performance when treated using conventional dyeing methods. In this study, coloration of meta-aramid fabrics was performed at room temperature utilising diazonium salts from weakly basic aromatic amines and was achieved via in situ construction of azo chromophores on the meta-phenylenediamine moiety. To promote diazonium-salt penetration into the meta-aramid fibre

Dyeing of polyamide fabrics with a reverse micellar system using soybean oil as a solvent Coloration Technol. (IF 1.8) Pub Date : 2023-05-18 Letícia Fantinati Guimarães, Miguel Angelo Granato
The current study reports the results of non-aqueous dyeing on polyamide fabrics based on a reverse micellar system composed of a stable emulsion of soybean oil, a co-surfactant, a nonionic surfactant and acid dyes. The system does not make use of water or electrolytes and significantly reduces the dyebath volume. The influence of the hydrophilic lipophilic balance of the surfactants was evaluated

Natural dyeing of air plasma-treated wool fabric with Rubia tinctorum L. and prediction of dyeing properties using an artificial neural network Coloration Technol. (IF 1.8) Pub Date : 2023-05-18 Can Eyupoglu, Seyda Eyupoglu, Nigar Merdan, Zeynep Omerogullari Basyigit
In this study, the ecological dyeing process of wool fabrics was investigated. Wool fabric samples were treated with atmospheric pressure plasma-jet and corona discharge plasma to modify the surface to make the process sustainable and greener. The samples were dyed with the aqueous extract procured from the powdered roots of Rubia tinctorum L. (madder) using the ultrasonic-assisted method. Scanning
