Chemical fiber fabric rapid desizing device and using method thereof

Abstract

The invention discloses a chemical fiber fabric rapid desizing device and a using method thereof. The device comprises a fixed mechanism, a moving mechanism and a desizing mechanism. A produced chemical fiber fabric is placed between an upper clamping arm and a lower clamping arm, so that the chemical fiber fabric is clamped, the stability of the position of the chemical fiber fabric is guaranteed, the chemical fiber fabric is prevented from falling off, and the desizing efficiency of the chemical fiber fabric is improved. A lifting control box controls a lifting shaft to move downwards. Whenthe clamped chemical fiber fabric is immersed in an alkali solution washing tank, desizing is carried out on the chemical fiber fabric by using an alkaline solution in the alkaline solution washing tank, a motor is started, a rotating shaft drives the chemical fiber fabric to rotate in the alkali solution washing tank, and therefore complete desizing of the chemical fiber fabric is guaranteed. A movable connecting block is pushed, so that the clamped chemical fiber fabric is immersed into a clear water tank; the rotating shaft drives the chemical fiber fabric to rotate in the clear water tank,so that the alkaline solution attached to the chemical fiber fabric is removed, and the desizing process is completed. The chemical fiber fabric fast desizing device has the advantages of being highin desizing efficiency and good in desizing effect, avoiding manual operation and reducing the labor cost.

Description

technical field [0001] The invention relates to the technical field of production of chemical fiber fabrics, in particular to a rapid desizing device for chemical fiber fabrics and a method for using the same. Background technique [0002] Desizing is the process of removing size from fabrics. The warp yarns of fabrics such as cotton, viscose and synthetic fibers are mostly sizing before weaving. Sizing affects fabric wettability during dyeing and finishing and hinders chemical contact with fibers. Therefore, fabrics are generally desized first. Cotton fabric desizing also has the function of removing some impurities in the fiber; sometimes synthetic fiber fabrics can be desized at the same time during the scouring process. In the fabric production process, because the size will affect the wettability of the fabric during the dyeing and finishing process, and It will hinder the contact of chemicals to the fabric, so the fabric must go through the desizing step. In additio...

Cotton fabric desizing also has the function of removing some impurities in the fiber; sometimes synthetic fiber fabrics can be desized at the same time during the scouring process. In the fabric production process, because the size will affect the wettability of the fabric during the dyeing and finishing process, and It will hinder the contact of chemicals to the fabric, so the fabric must go through the desizing step. In addition, the desizing of the cotton fabric also has the effect of removing impurities in the fiber. The desizing method is different with the size used for sizing. , there are mainly hot water desizing method, lye desizing method, enzyme desizing method, oxidant desizing method, all desizing methods need to use desizing machine, desizing machine is a machine to remove the size on the fabric, The current desizing machine is a cylindrical closed space with two cloth guide rollers inside. The steps of washing and other steps are all carried out in this closed space. The washing space is small and the washing effect is poor, which affects the desizing effect and desizing cost. High, low desizing efficiency
