Fabric printing and dyeing pre-wetting device and method

Abstract

The invention discloses a fabric printing and dyeing pre-wetting device. The fabric printing and dyeing pre-wetting device comprises a pre-impregnation tank, a printing and dyeing tank, and a feedingguide roller and a discharging guide roller which are used for guiding the movement of a fabric, wherein a water immersion guide roller set and a printing and dyeing guide roller set are mounted in the pre-impregnation tank and the printing and dyeing tank respectively; after the fabric passes through the feeding guide roller, the fabric is wound into the water immersion guide roller set and thenenters the printing and dyeing tank; after the fabric is wound around the printing and dyeing guide roller set in the printing and dyeing tank, the fabric is output from the discharging guide roller;an extruding roller for extruding and dehydrating the fabric and a leveling roller for taking out folds are mounted at a position between the pre-impregnation tank and the printing and dyeing tank. The fabric printing and dyeing pre-wetting device disclosed by the invention has the beneficial effects that the extruding roller and the leveling roller are arranged between the pre-impregnation tank and the printing and dyeing tank, and can be used for guiding water extruded by the extruding roller to flow back into the pre-impregnation tank and preventing a condition that a lot of the water fromentering the printing and dyeing tank so that the concentration of a dyestuff in the printing and dyeing tank is obviously reduced is prevented; relatively great influences on the quality of final finished products are not caused; the fabric also can be leveled to eliminate the folds, so that the printing and dyeing quality is improved.

Description

Technical field [0001] The invention relates to the technical field of fabric or cloth printing and dyeing, in particular to a cloth printing and dyeing pre-wetting device and a pre-wetting method. Background technique [0002] Because printed fabrics often have certain impurities on the surface before they are dyed, and due to the differences in the material properties of various fabrics, the dyes sometimes cannot fully adhere to the fabrics. Therefore, it is necessary to perform pre-treatment on the fabric before printing and dyeing, and printing and dyeing pre-wetting is one of the pre-treatment processes on the fabric. However, the current printing and dyeing pre-wetting is often done manually, which is not efficient and the pre-wetting effect is not good. [0003] For example, CN 207295194 U discloses a high-efficiency fabric printing and dyeing pre-wetting device, which can pre-wet the fabrics to be printed and dyed, which not only plays a role in cleaning the fabrics, but a...

Problems solved by technology

However, at present, the pre-wetting of printing and dyeing is often done manually, which is not efficient and the pre-wetting effect is not good.

[0003] Such as CN 207295194 U discloses a kind of high-efficiency cloth printing and dyeing pre-wetting device, which can carry out pre-wetting treatment to the cloth for printing and dyeing, which not only plays a role in cleaning the cloth, but also facilitates the adhesion of dyestuffs when printing and dyeing, and improves the At the same time, the water used for pre-wetting can be reused, which reduces the waste of water; but there is a fatal problem: when the cloth enters the dye tank from the clear water tank, due to the moisture absorbed on the cloth, the water Dissolving in the dye tank will cause the concentration of the dye to drop, affecting the final printing and dyeing quality
