Heavy fabric uniform dyeing process

Abstract

The invention discloses a heavy fabric uniform dyeing process. A fixed bracket is fixedly arranged at the bottom of a dye vat of a used high-temperature rapid dyeing machine, and a rotatable roller is fixedly arranged on the fixed bracket; a roller is connected with the output end of a power source, and the output end of the power source can drive the roller to rotate; the roller rotates to drive fabric in the dye vat to move; the rotating speed of the roller is 25-100 r / min; and the flowing speed of a dye liquor in the dye vat is 0.32-0.61 m / s. According to the heavy fabric uniform dyeing process, the roller is fixedly arranged at the bottom of the dye vat and is driven by the power source to rotate. Especially, when the heavy fabric is locally accumulated when being dyed, the roller rotates to drive the heavy fabric to move, and the proper roller rotation speed is used, so that uneven heating of the fabric at the accumulation position is avoided, the problems of dyeing defects, uneven dyeing and the like of the fabric are avoided, and the dyeing quality of a product is improved.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a uniform dyeing process for heavy fabrics. Background technique [0002] Generally, the dyeing machine puts the dye liquid and the dyed cloth in a long or circular cloth storage tank, and is driven by the dye liquid sprayed out by a cloth lifting wheel and a nozzle, and the dyed cloth is taken out of the cloth storage tank. It is lifted inside, and then enters the end of the cloth storage tank through the cloth guide pipe, and runs in this way to complete the dyeing of the cloth. [0003] When dyeing heavy fabrics with a high-temperature fast dyeing machine, due to the high weight of the fabric, it is easy to form local accumulations inside the dyeing tank of the dyeing machine, and the heating is uneven, resulting in color spots, uneven dyeing, and sometimes knotting and cloth blocking Phenomenon. How to solve the problem of partial accumulation of heavy fabrics in the dyeing ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a uniform dyeing process for heavy fabrics, which adopts an actively rotating roller under the fabric, so that when the heavy fabrics are piled up, the rollers actively rotate to drive the movement of the heavy fabrics, thereby solving the problem of heavy fabrics in the dyeing machine. Partial accumulation in the dyeing tank, so as to solve the problem of color flower and uneven dyeing
