Dyeing machine for dip-dyed cloth

Abstract

The invention discloses a cloth dyeing machine for dip-dyeing cloth, which comprises a dyeing tank filled with dyeing liquid; a cover plate sealingly matched with the dyeing tank; and a vacuum device for evacuating the gas inside the dyeing tank; The cloth rolling device is used to wind the cloth and immerse the cloth in the dye liquor; the driving device is used to drive the cloth rolling device to wind the cloth back and forth in the dye liquor; the heating device is used to heat the dye liquor in the dyeing pool to preset temperature. The present invention can heat up the dyeing liquor in the dyeing pool by setting the heating device, so that the temperature of the dyeing liquor in the dyeing pool reaches a preset value, increases the temperature of the dyeing liquor, improves the activity of the dye in the dyeing liquor, so that the dyestuff can be better It is attached to the fabric, and because the temperature of the dye solution rises, the drying rate of the fabric can be improved in the subsequent drying process.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, in particular to a cloth dyeing machine for dip-dyed cloth. Background technique [0002] Dip dyeing is also called exhaust dyeing. Dye application term. The method of immersing the dyed object in a dye bath containing dyes and required auxiliaries, and gradually dyeing the dyed object with the dye through the circulation of the dye bath or the movement of the dyed object. One of the current dip-dyeing processes for fabrics is to directly spread the entire fabric into a dye solution with a certain temperature, and then stir the fabric to fully absorb the dye. The dyeing method is The advantage is that the fabric is evenly colored during the dyeing process, so the quality of the dyed fabric is high, but because the fabric is stirred by external forces during the dip-dyeing process, a large number of wrinkles will appear on the originally flat fabric, resulting in the need for...

Problems solved by technology

One of the current dip-dyeing processes for fabrics is to directly spread the entire fabric into a dye solution with a certain temperature, and then stir the fabric to fully absorb the dye. The dyeing method is The advantage is that the fabric is evenly colored during the dyeing process, so the quality of the dyed fabric is high, but because the fabric is stirred by external forces during the dip-dyeing process, a large number of wrinkles will appear on the originally flat fabric, resulting in the need for more dyeing in the later stage. Second leveling, which will affect the quality of the fabric

[0003] The other is to set the rotating roller, and the cloth passes through the rotating roller. In this process, because the rotating roller is located in the dye solution, part of the cloth will be in the dye solution when passing, thereby realizing the continuous dipping of the cloth. This method is suitable for dip dyeing of very long cloth, but because the cloth only passes through the dyeing tank, although the cloth as a whole can remain flat during this process, but because the cloth passes directly through the process, the amount of dye dyed on the cloth Less, its dyeing effect is poor, and it is not suitable for dyeing with shorter length fabrics

[0004] During the dyeing process, if the dyeing solution is not heated up, it will cause low dye activity, resulting in the inability of the dye to attach to the fabric fibers quickly and effectively, which will easily cause uneven dyeing and poor dyeing effect. It affects the effect of dip-dyeing the fabric; the dye will deposit during the dyeing process, which causes the concentration of the upper part of the dye to be low
