Problems solved by technology

Zhao Qiming reported that the application of ultrasonic waves on cotton fabrics to the one-bath method of enzymatic oxygen descouring and bleaching of cotton fabrics will accelerate the activity and diffusion rate of enzyme molecules, thereby improving the efficiency of the one-bath method of descouring and bleaching cotton fabrics. The one-bath method of oxygen descouring and bleaching is not significant
We have studied the use of ultrasonic pretreatment before the one-bath method of descouring and bleaching of cotton fabrics, which can effectively shorten the descouring and bleaching time and improve the descouring and bleaching effect, but it cannot reduce the descouring and bleaching temperature.

Abstract

The invention discloses an ultrasonic-assisted low-temperature one-bath desizing, scouring and bleaching pre-treatment method for cotton fabrics and relates to the technical field of application of ultrasonic waves to one-bath desizing, scouring and bleaching pre-treatment of the cotton fabrics. The cotton fabrics are subjected to the one-bath desizing, scouring and bleaching pre-treatment under the action of the ultrasonic waves; the ultrasonic power is 50w, the treatment temperature is 70 DEG C and the treatment time is 30 minutes; the desizing rate of the fabrics is 96.7 and the capillary effect is 10.3. With the adoption of the ultrasonic-assisted low-temperature one-bath desizing, scouring and bleaching pre-treatment method, the desizing, scouring and bleaching effects on the cotton fabrics are good, energy is saved, consumption is lowered, process time is shortened and the pre-treatment temperature is lowered; the method can replace a traditional one-bath desizing, scouring and bleaching process of the cotton fabrics.

Description

Technical field [0001] An ultrasonic-assisted one-bath pre-treatment method for low-temperature desiccation, scouring and bleaching of cotton fabrics relates to the technical field of the application of ultrasonic waves in the one-bath pretreatment of cotton fabrics. Background technique [0002] The traditional one-bath pre-treatment process of de-scouring and bleaching of cotton fabric has problems such as long process flow, long working hours, high temperature, more water, and serious pollution, especially the temperature, the general chemical de-boiling and bleaching process is difficult to be below 80 ℃ To achieve good results. At present, the physical optimization methods for the one-bath de-scouring-bleaching method are mainly microwave and plasma methods. These methods have obvious effects in pre-treatment, which can shorten the processing time or reduce the processing temperature. However, the entire process requires more equipment. High, low security. During the propa...
