Description

Equipment for printing and dyeing cloth

Technical Field

The invention belongs to the technical field of textile printing and dyeing, and particularly relates to equipment for printing and dyeing cloth.

Background

The cloth printing and dyeing technique is fairly ripe at present, current cloth printing and dyeing is usually carried out through dip-dyeing and spray-painting two kinds of modes, wherein dip-dyeing is in the middle of directly soaking the cloth into the dye liquor, make the dye liquor in the absorption dye vat that the cloth can be abundant, this mode has realized the even effect of cloth dip-dyeing in-process cloth, and because the time of dip-dyeing in-process cloth and dyestuff contact is long, the adhesion effect of dyestuff on the cloth is good, thereby its color and luster of the cloth that dyes out is bright-colored, the fastness is high.

However, the dip dyeing also has a defect that the dye is absorbed because the cloth is directly immersed in the dye, and at the initial stage of the dip dyeing, the concentration of the dye in the dye bath is high, so that the color degree of the initial cloth dyeing is high, the consistency of the cloth dyeing and the expected color can be ensured, and the cloth continuously enters and then goes out in the dye liquor at the later stage, and the concentration of the dye liquor in the dyeing process is continuously reduced because the dye is absorbed by the cloth at the earlier stage, so that the quantity of the dye attached to the cloth is reduced, and the later stage is reached, the color of the cloth is lighter, and the overall quality of the cloth is affected.

After printing and dyeing the cloth and accomplishing, need dry to the cloth, current drying device dries through hot-blast usually, and it is direct blow the cloth with hot-blast at the in-process of drying on, but at the in-process of drying, the dyestuff on the cloth that hot-blast can be blown takes place the displacement, causes the dyestuff uneven on the cloth, influences the color and luster of cloth.

Disclosure of Invention

The invention provides the equipment for printing and dyeing the cloth, which has a simple structure and a good drying effect and is used for overcoming the defects of the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme: an apparatus for printing and dyeing cloth comprising
