Front and back steam pad dyeing equipment and method thereof

Abstract

The invention provides front and reverse steam rolling dyeing equipment. The equipment comprises a cloth conveying device, a dye padding device, a cloth front steam rolling dyeing device, a cloth reverse steam rolling dyeing device and a finished product collecting device, all of which are sequentially arranged in the conveying direction of cloth. The cloth front steam rolling dyeing device comprises a first rack, a first driving assembly, a first heating large wheel, a first high-temperature-resistant conveying belt and a first supporting guide wheel set. A second driving assembly is used for driving a second heating large wheel to rotate. A second supporting guide wheel set comprises multiple second supporting guide wheels. The cloth front steam rolling dyeing device and the cloth reverse steam rolling dyeing device of the front and reverse steam rolling dyeing equipment are used for carrying out steam rolling dyeing operation on the cloth containing dye liquor, cloth fibers can better adsorb dye molecules, the utilization rate of dye is high, the color yield is high, and the color fastness is high. The problem that the chromatic aberration exists between the front face and the reverse face of the cloth can be solved, the dyeing effects of the front face and the reverse face of the cloth are more consistent accordingly, the chromatic aberration is low, and the quality is higher.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to a front and back steam pad dyeing equipment and a method thereof. Background technique [0002] As we all know, disperse dyes will be sublimated into gas under certain temperature conditions, and a considerable part of the dye molecules in the traditional thermosol sublimation dyeing process are not absorbed in the fabric fibers after sublimation, but volatilize into the atmosphere Therefore, traditional dyeing equipment and dyeing methods have the problems of low dye utilization rate, light color yield and poor color fastness. [0003] It should also be pointed out that when the existing dyeing equipment is dyeing, there will be a problem of color difference between the front and back of the cloth, and the dyeing effect on the front and back of the cloth will be inconsistent. Contents of the invention [0004] Based on this, it is necessary to provide a f...

AI Technical Summary

Problems solved by technology

[0002] As we all know, disperse dyes will be sublimated into gas under certain temperature conditions, and a considerable part of the dye molecules in the traditional thermosol sublimation dyeing process are not absorbed in the fabric fibers after sublimation, but volatilize into the atmosphere , so the traditional dyeing equipment and dyeing methods have the problems of low dye utilization rate, light color yield and poor color fastness.

[0003] It should also be pointed out that when the existing dyeing equipment is dyeing, there will be a problem of color difference between the front and back of the cloth, and the dyeing effect on the front and back of the cloth is inconsistent.
