Description

Technical Field

[0001] The utility model relates to the technical field of grey cloth desizing, in particular to a desizing device for producing pure cotton grey cloth. Background Art

[0002] Natural fibers all contain natural impurities, as well as various slurries added during the textile process and oil stains. These impurities will affect the physical and mechanical properties of the fibers to varying degrees, reduce the wettability of the fabric, make it rough and have poor whiteness. In the dyeing and printing process, they will also hinder the dyeing of the dye, making the color dull and the dyeing fastness poor. Therefore, whether it is bleaching, dyeing or printing products, they generally need to be smelted and bleached. The purpose of smelting and bleaching is to use chemical and physical effects to remove various impurities on the fibers, so that they can obtain a white luster, soft touch and good permeability to meet the requirements of wearing, and provide qualified semi-finished products for post-processing. Desizing is to use chemical effects to treat the fibers.

[0003] The desizing of pure cotton grey cloth can be carried out by different methods according to the impurity content of the original cloth and the need for desizing, such as enzyme desizing, alkali desizing, acid desizing, oxidant desizing, etc., and in the existing grey cloth desizing device, the desizing process in the device is not perfect, and the grey cloth cannot be desizing well. For example: Publication No. CN212611372U discloses a desizing device for producing pure cotton grey cloth, including a machine body, a power supply group, a first motor, a first transmission shaft, a second motor, a second transmission shaft, a third motor, a third transmission shaft, a fourth motor, a fourth transmission shaft, a first active rod, and a first active wheel. , a first driven wheel, a first driven rod, a second driven wheel, a second driven rod, a second active rod, a second active wheel, a third active rod, a third active wheel, a fourth active rod, a fourth active wheel, a first desizing groove, a second desizing groove, a third driven rod, a third driven wheel, a fourth driven rod, a fourth driven wheel, a desizing component and a discharge port. A desizing component is arranged at the middle position inside the machine body, and a discharge port is arranged on the right end surface of the desizing component, which solves the problem of incomplete desizing of the original device and improves the desizing effect of the utility model. The utility model has a reasonable structure, good desizing effect and strong practicality.

[0004] In the above-mentioned desizing device, the sodium hydroxide solution in the first desizing tank and the dilute sulfuric acid solution in the second desizing tank are mainly used for desizing the pure cotton grey cloth.

At the same time, the pure cotton grey cloth will carry a large amount of sodium hydroxide solution after coming out of the first desizing tank and then entering the second desizing tank. After long-term use of the device, the composition of the desizing solution in the second desizing tank will be affected, so that the desizing effect is greatly reduced.

[0005] Therefore, it is particularly important to design a desizing device for producing pure cotton grey cloth to solve the above-mentioned defects. Utility Model Content
