co2 laser treatment as a clean process for treating Denim fabric
Journal of Cleaner Production, 2014Co-Authors: C W KanAbstract:Abstract In this study, a carbon dioxide (CO 2 ) laser was used for the colour-fading treatment of Denim fabrics. Two types of Denim fabrics were laser-treated: one was manufactured with low-twist yarn spun by torque-free ring-spinning technology, and the other was manufactured by conventional ring-spun yarn. Commercially available torque-free ring-spun cotton yarn was used to manufacture the Denim fabrics. For comparison, one specimen of Denim fabric featured torque-free ring-spun yarn in the warp direction and conventional ring-spun yarn in the weft direction, whereas another specimen featured conventional ring-spun yarn in both the warp and weft directions. The warp yarn of both specimens was dyed by the same indigo dyeing process. The Denim fabric samples were treated with a CO 2 laser under the same conditions, and two laser processing parameters, namely, (i) resolution and (ii) pixel time, were used to adjust the laser power. After laser treatment, the colour properties (reflectance and colour parameters of the fabrics, such as the K/S value (the Kubelka-Munk function was used to represent the colour yield of the fabrics, where K is absorption and S is scattering) and CIE L * a * b * values) and dimensional stability of the Denim samples were compared, and the results were analysed thoroughly. In addition, the colour-fading effect induced by CO 2 laser treatment was compared with that induced by conventional cellulase treatment. Experimental results revealed that CO 2 laser treatment is an effective alternative means of producing the colour-fading effect in Denim fabrics if the processing parameters can be carefully controlled.

Effect of laser treatment on pigment printing on Denim fabric: low stress mechanical properties
Cellulose, 2020Co-Authors: Shun-ting Tse, Chi-wai KanAbstract:In textile and fashion industry, it is common to combine laser treatment and pigment printing processes for creating special design and aesthetic effects. Other than aesthetic effects, comfort is also a concern to the customer. This paper examines comfort properties, in terms of low stress mechanical properties, of laser treated and pigment printed Denim fabric. Tensile, shearing, bending, compression and surface properties were examined by Kawabata evaluation system for Fabric under standard procedure. It was noted that tensile, shearing, bending and compression properties of the Denim fabric were affected by laser treatment and pigment printing. This influence could be caused by action of the laser during the treatment as laser can damage the fabric and yarn, and can also burn the fabric surface. The pigment used in printing forms a thin layer on fabric surface making the Denim fabric more rigid and difficult to deform. Moreover, surface properties of Denim fabric samples were not affected by laser treatment or pigment printing and nor was there any effect of the two combined treatments. The Denim fabric samples became smoother and had an even surface.

Washing techniques for Denim jeans
Denim, 2015Co-Authors: Chi-wai KanAbstract:Abstract Denim garment and jeans washing is a well established process for producing fashion items for leisure wear. The evolution of Denim washing and the different washing techniques are discussed in this chapter. New environmentally friendly processes, which are leading to zero effluent discharge, are identified. In addition, the machines used to achieve different washing effects are reviewed. Quality issues such as the factors affecting washing and problems associated with Denim garment washing are also provided as reference points for practical usage and quality assurance.

Effect of Enzyme Washing on the Tensile Property of Denim Fabric
Advanced Materials Research, 2014Co-Authors: Chi-wai KanAbstract:Denim is one important clothing product recently in the market. However, the original solid blue colour is not attractive to the consumers and hence many manufacturers are trying to remove part of the blue colour from the Denim fabric surface. This fading effect could impart fade-look or worn out effect in the final products which made it becomes popular to the consumers. There are different methods to achieve the colour fading effect in which enzyme washing is one of the simplest methods to be used in the industry. Although the enzyme washing is a good method for colour fading of Denim, the process involves the use of chemical as well as temperature which may introduce certain degree of damage in Denim fabric. Thus, this paper will investigate the effect of enzyme washing on the tensile property of Denim fabric under different treatment duration.

2011Co-Authors: Ahmet Özbek, Mehmet AkalinAbstract:In this study, Turkey’s Denim trousers export to Germany was predicted using ANN models. ANN models were composed of the import of Denim trousers, the minimum wage, the price of cotton, electricity, and water, the value of TRY against USD, the credit usage of ready-made clothing enterprises, export credits, the real effective exchange rate, brands of Denim trousers, the Denim trouser Balasa Index, Germany Denim Trousers import, Germany's Quota Application to Turkey, Income Per Capita in Germany, Population in Germany, Unemployment in Germany and Inflation in Germany. It is observed that the best prediction is provided by ELMAN.
