Developing Sustainable Methods for Softener and Fixing Agent Application in HT Dyeing Machines

Abstract

Global warming, which is one of the problems brought by the increasing population day by day, and the rapid depletion of water resources have increased the restrictions on water use. Thus, more environmentally friendly and sustainable production processes are developed by producers and consumers. The number of studies carried out to minimize the use of raw materials in textile dyehouses is increasing day by day. The high chemical load, waste water usage rate and energy cost resulting from pretreatment, dyeing and other processes vary according to the processes used in textile factories.
 Our company aims to support environmentally friendly studies that contribute to the economy in production processes. While producing in the paint shop, energy, water, chemicals, etc. It also aims to use raw material resources sparingly. In this study, the efficiency studies carried out in HT dyeing and finishing processes in the dyehouse of our company were examined. By optimizing the post-processing performed in HT machines after dyeing, softener and fixator chemicals applied in HT machines were carried out by using double pads before drying in stenter machines after trials. Obtained results were compared with old methods. A sustainable new method has been developed without any color, fastness or touch difference between the old system and the new system.
 With this new process study, our company's water, energy and chemical savings and the company's impact on the environment have been reduced, while time savings have been achieved by shortening the process time. In the test results, there was no problem in washing, color and rubbing fastness efficiency. No change was observed in the touch of the products after the application of the softener step with the impregnation method instead of shrinking. As a result of the study, while the water consumption was reduced by 20%, the process time was also reduced by 19%.
