Design of an ultrasonic washing process as an after-treatment for developing reactive printing quality and fastness

In the textile industry, washing process after printing or dying is very costly for the companies because it needs more energy, water, chemical and time during the process. Eventhough more money is spent for washing, usually the obtained consequences like fastness, fabric strength are not satisfactory. It can be said that end product quality depends on the washing process even if previous processes which the fabric is treated until washing process is perfect. The technology used now for washing does not give the desired result in terms of quality and cost, and producers are waiting for a newly enhanced and designed process for washing. The main aim of this study is to propose a new washing process. This survey has been carried on by using industrial standards and international test methods related with washing and fabric quality. As a result, a new washing method will be proposed at the end of the studies.
