Supercritical co2 anhydrous rotary warp beam horizontal dyeing kettle and its dyeing system

Abstract

The invention relates to a supercritical CO2 anhydrous rotating warp beam horizontal type dyeing kettle and a dyeing system thereof. The supercritical CO2 anhydrous rotating warp beam horizontal type dyeing kettle comprises a dyeing kettle body, a kettle cover, a dyeing fabric frame and a dyeing kettle heating and cooling device, wherein a dyeing cavity is formed inside the dyeing kettle body, the dyeing fabric frame comprises a hollow dyeing warp beam, air exhaust micropores are distributed in the wall of the dyeing warp beam, and the dyeing kettle body is provided with a dyeing kettle air outlet enabling the dyeing cavity to be communicated with the outside for air exhausting; the dyeing kettle body is arranged in a horizontal mode, and the dyeing warp beam is rotationally supported and connected inside the dyeing kettle body in a horizontal mode; an air suction cavity which is parallel to the dyeing cavity in an isolated mode is formed inside the dyeing kettle body, one end of the dyeing warp beam stretches in the air suction cavity and is provided with a warp beam air suction hole, the dyeing kettle body is provided with a dyeing kettle air inlet and a rotation driving device, the dyeing kettle air inlet enables the air suction cavity to be communicated with the outside for air suction, and the rotation driving device drives the dyeing warp beam to rotate. According to the supercritical CO2 anhydrous rotating warp beam horizontal type dyeing kettle and the dyeing system thereof, a vertical dyeing mode is changed into a horizontal dyeing mode, influence of gravity factors on the dyeing effect is overcome, the problem that cloth is dyed unevenly in the prior art is solved, the uniform dyeing effect is achieved, and production efficiency is improved.

Description

technical field [0001] The invention relates to a textile dyeing device, in particular to a supercritical CO 2 An anhydrous rotary warp beam horizontal dyeing kettle and its dyeing system, the dyeing device can use supercritical CO 2 Implement short-cycle, efficient, and pollution-free textile dyeing. Background technique [0002] Traditional textile dyeing uses water as a medium to carry dyes for dyeing. The whole process requires auxiliaries and consumes a lot of water and produces pollutants. It is a process with high energy consumption and high pollution. Although the industry has developed a series of low bath ratio, Low-salt dyeing technology, but the pollution problem in the printing and dyeing industry is still very serious, which not only affects the sustainable development strategy, but also becomes a bottleneck for the development of the printing and dyeing industry. [0003] Waterless dyeing is regarded as a revolution in the traditional dyeing and finishing in...
