Description

Technical Field

[0001] The present invention belongs to the technical field of fabric desizing, and particularly relates to a desizing device for textile fabric production. Background Art

[0002] In the production process of textile fabrics, in order to enhance the abrasion resistance, smoothness, antistatic property of warp yarns, and at the same time improve the strength and cohesion of yarns and their weavability, it is usually necessary to perform sizing processing on warp yarns before weaving, which is also called slashing. During the sizing process, part of the sizing agent penetrates between fibers and adheres to the surface of warp yarns. This is particularly crucial for the wide use of high-speed looms (such as air-jet looms and water-jet looms). However, while the sizing agent improves the performance of yarns, it also pollutes the dyeing and finishing processing liquid and hinders the chemical reaction between fibers and dyeing and finishing chemicals, thus affecting the smooth progress of dyeing and finishing processing. Therefore, desizing has become a necessary step in textile fabric production. The purpose of desizing is to remove the paste or resin coating on the fabric to improve the softness and hygroscopicity of the fabric. The desizing method varies according to the type of sizing agent used. Common methods include alkali desizing, enzyme desizing, acid desizing, and oxidant desizing, etc. Alkali desizing uses hot alkali solution to cause the sizing agent to swell and change from a gel state to a sol state, facilitating washing and removal; enzyme desizing catalyzes the hydrolysis reaction of starch macromolecular chains through the action of enzymes to generate low-molecular-weight compounds, which are removed by water washing; acid desizing uses the chemical action of acid to cause the hydrolysis of the sizing agent.

[0003] Existing desizing devices have some problems during use, such as waste of cleaning liquid during desizing, incomplete desizing, and relatively long desizing time, etc. These problems not only affect the production efficiency of textile fabrics but also may have an adverse impact on subsequent dyeing and finishing processing. Therefore, it is urgent to design a desizing device for textile fabric production that is efficient, environmentally friendly, energy-saving, and easy to operate to solve the above problems, improve the desizing effect and efficiency, and ensure the quality of textile fabrics.
