Investigation of the Properties of Denim Fabrics Dyed with a Short Process with Sulfur Dyeing

Abstract

The major role played by the textile industry in environmental pollution, sustainability of resources, and the proliferation of competitors have imposed many responsibilities on business. Important among these duties is producing environmentally friendly products, fit for purpose, and cheap; while using less water, chemicals, energy and time. In this study, an innovative dyeing method is developed as an alternative to conventional sulfur-dying applied in rope dying. Innovative feature of this study is that the developed dyeing process is an environmentally friendly process based on the decrease in the amount of use of water, chemicals, etc. By this new process, conventional denim fabric properties have been tried to be obtained with less processes, use of water and chemicals. The color and selected performance values of fabrics dyed using both of these methods were comparatively examined. According to the results; the properties of fabric treated with the newly developed dyeing method, which has lower consumption are very similar to those of the conventionally dyed fabrics. The warp tensile and tear strength values of the fabrics dyed using the innovative method decreased, while the values in the weft direction increased. Fabric dyed with the conventional method has the highest K/S value, but the lowest L* value. The rubbing fastness value of the fabric dyed with the innovative method was better.
