Problems solved by technology

[0003] Usually, in the desizing process, in order to fully hydrolyze the starch, it needs to be stacked for a long time, and the long stacking time is not only not conducive to the efficiency of the desizing process, but also affects the catalytic activity of the enzyme, thereby weakening the Desizing effect

Embodiment Construction

[0027] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0028] A cotton fabric printing, dyeing and desizing pretreatment equipment, such as figure 1 As shown, it includes a pre-washing box 1, and the pre-washing box 1 contains warm water for pre-washing cotton fabrics.

[0029] In order to improve the pre-cleaning effect of cotton fabrics, the impurities attached to the surface of cotton fabrics can be removed more efficiently. figure 1 As shown, an air passage 3 is horizontally arranged in the bottom of the pre-water washing box 1, the air passage 3 extends to the outside of the pre-water washing box 1 and is connected with a blower 2, and a plurality of suspensions connected to the air passage 3 are arranged on the air passage 3 Sprinkler 4. The blower 2 is used to introduce gas, and the fine air bubbles produced by the suspending nozzle 4 enter the warm water to form an air flotation c...

Abstract

The invention discloses cotton fabric printing, dyeing and desizing pretreatment equipment and a pretreatment process. The equipment comprises a pre-washing tank, a vertical plate is arranged on one side of the pre-washing tank, a water containing tank is defined by a lower baffle, the vertical plate and the pre-washing tank jointly, a hot air spray head is arranged above the water containing tank, and the hot air spray head is communicated with an air heater; a padding box is arranged at the downstream of the containing groove, and a supporting frame is erected in the padding box; the padding box is fixedly located on the ultrasonic box, and a vibration steel plate is arranged between the padding box and the ultrasonic box in a spaced mode. An ultrasonic generator and an ultrasonic transducer are installed in the ultrasonic box, and the ultrasonic transducer acts on the vibrating steel plate. According to the method, the cotton fabric is pretreated under the synergistic effect of ultrasonic waves, and sizing starch is promoted to enter a catalytic part of enzyme more quickly under the microflow effect of the ultrasonic waves, so that the catalytic efficiency of the enzyme is improved, the stacking reaction time of desizing treatment is shortened, and the desizing efficiency is improved. And the shortened stacking reaction is beneficial to maintaining the high-activity catalytic action of the enzyme.

Description

technical field [0001] The invention relates to a pretreatment device and a process, in particular to a cotton fabric printing, dyeing and desizing pretreatment device and a pretreatment process. Background technique [0002] When weaving woven fabrics, the warp yarns will be repeatedly subjected to friction and tension, resulting in yarn fluff and yarn breakage. In order to make the weaving process go smoothly, the warp yarns are usually sizing before weaving. However, the existence of pulp will hinder the subsequent dyeing process and affect the penetration of dyestuffs into the fiber. Therefore, in the dyeing and finishing process, the desizing treatment with the main purpose of removing the pulp should be carried out first. Cotton fabrics are usually sizing with starch sizing or a mixed sizing of starch and PVA; in the prior art, the enzymatic desizing treatment method can efficiently decompose the starch sizing on the fabric, and the components contained in the washing ...
