A device for printing and dyeing cloth

Abstract

The invention discloses a kind of equipment for printing and dyeing cloth, which comprises a dyeing pool, containing dye liquor used for dip-dyeing cloth; a cloth passing roller, used for introducing cloth into the dye liquor; being connected with the dyeing pond to supply liquid Pipes and drain pipes; feeding device, which cooperates with the cloth passing roller, extracts part of the dyeing liquid in the dyeing pool to dissolve part of the solid dye, and sprays it from the bottom of the dyeing pool into the dyeing pool to mix with the original dyeing liquid after the solid dye is dissolved Uniform; squeeze liquid device, used to squeeze out excess dyeing liquid on the cloth after dyeing; drying device, used to pre-dry the cloth after dyeing, and then dry the cloth. The present invention is provided with a drying device, which can pre-dry the cloth during the drying process, and then dry the cloth. The drying process has high drying efficiency. When drying, the temperature of the cloth is raised first, and then the cloth is dried Drying is carried out. During the drying process, it can effectively ensure that the dye on the cloth is deposited on the cloth, and ensure that the color of the cloth is high when it is dried.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, in particular to a device for printing and dyeing cloth. Background technique [0002] The cloth printing and dyeing technology is quite mature at present. The existing cloth printing and dyeing is usually carried out in two ways: dip dyeing and spray dyeing. Among them, dip dyeing is to directly immerse the cloth into the dyeing liquid, so that the cloth can fully absorb the dyeing liquid in the dyeing pool. This method realizes the effect of uniform dyeing in the process of cloth dyeing, and because the time of contact between the cloth and the dye is long in the process of dip dyeing, the adhesion effect of the dye on the cloth is good, so that the dyed cloth has bright color and high fastness. [0003] However, there are also defects that cannot be ignored in exhaust dyeing. Because the cloth is directly immersed in the dye to absorb the dye, in the initial stage of exhaus...

AI Technical Summary

Problems solved by technology

[0003] However, there are also defects that cannot be ignored in exhaust dyeing. Because the cloth is directly immersed in the dye to absorb the dye, in the initial stage of exhaust dyeing, the dye concentration in the dyeing pool is relatively high, so the initial color of the cloth is high. The expected color is consistent, and as the cloth continuously enters and then goes out of the dye solution in the later stage, the concentration of the dye solution during the dyeing process will continue to decrease because the cloth absorbs the dye in the early stage, resulting in the dye attached to the cloth. As the quantity decreases, the color of the fabric will become lighter in the later stage, which will affect the overall quality of the fabric

[0004] After the cloth is printed and dyed, the cloth needs to be dried. The existing drying device usually uses hot air to dry, and it directly blows the hot air onto the cloth during the drying process, but in the drying process , the hot air will blow the dye on the fabric to shift, resulting in uneven dye on the fabric and affecting the color of the fabric
