Embodiment Construction

[0006] Fabric: Cotton Poplin (40s x 40s, 118 x 89)

[0007] Conventional descouring and bleaching process: ultrasonic pretreatment time is 5min; NaOH 20g / L; 30% hydrogen peroxide 20g / L; oxygen bleaching stabilizer Na 2 SiO 3 7g / L; penetrating agent JFC4g / L; bath ratio 1:30 descouring and bleaching one bath time is 60min, water bath temperature is 85°C.

[0008] Ultrasonic pretreatment cotton fabric descouring and bleaching one-bath process: the first step, ultrasonic pretreatment: ultrasonic frequency 40kHz; ultrasonic power 100w; processing temperature 60 ℃; ultrasonic pretreatment time 5min; One bath of boiling and bleaching: NaOH 20g / L; 30% hydrogen peroxide 20g / L; oxygen bleaching stabilizer Na 2 SiO 3 7g / L; penetrant JFC 4g / L; liquor ratio 1:30, water bath temperature 85°C, act for 30min.

Abstract

The invention discloses a method of a pre-treatment of desizing, scouring and bleaching in a one bath process for a cotton fabric by an ultrasonic pre-treatment, and relates to the technical field of application of ultrasonic waves in the pre-treatment of desizing, scouring and bleaching in a one-bath process for the cotton fabric. The method comprises the following steps: before the pre-treatment of desizing, scouring and bleaching in the one-bath process for the cotton fabric, and carrying out the ultrasonic pre-treatment, wherein the ultrasonic frequency is 40kHz, the power is 100W, the processing temperature is 60 DEG C and the treatment is carried out for 5 minutes; then carrying out the conventional pre-treatment of desizing, scouring and bleaching in the one-bath process for the cotton fabric. The method provided by the invention is energy-saving and consumption-reducing and technical time-shortening, and can be used for replacing the conventional pre-treatment process of desizing, scouring and bleaching in the one-bath process for the cotton fabric.

Description

technical field [0001] The invention discloses a method for pre-treating cotton fabrics with one bath of descouring and bleaching by ultrasonic pretreatment, and relates to the technical field of application of ultrasonic waves in pre-treatment of cotton fabrics with one bath of descouring and bleaching. Background technique [0002] The traditional cotton fabric descouring and bleaching one-bath pretreatment process has problems such as long process flow, long working hours, high energy consumption, high water consumption, and serious sewage discharge. During the propagation of ultrasonic waves, the particles in the elastic medium vibrate and transmit energy along the direction of propagation, resulting in mechanical effects, thermal effects and acoustic cavitation, which can be applied to textile pretreatment, dyeing, finishing and washing processing, etc. , to optimize the process. Ultrasonic wave is applied to the one-bath treatment of cotton fabric descouring and bleac...
