Problems solved by technology

But there are also many problems: 1. Different dyes can be used in supercritical CO 2 The solubility in is not the same, at 120 degrees Celsius, the solubility of disperse red is 2.5 / mole fraction × 10 when the pressure is 24 MPa 6 , but the solubility of disperse blue at the same temperature is as high as 17.9 / mole fraction×10 6

specific Embodiment approach

[0033] see figure 1 , figure 2 , the present invention utilizes the above-mentioned supercritical CO 2 The specific embodiment of the method for anhydrous dyeing dye still, comprises the following steps:

[0034] (1) Firstly, place the weighed various dyes used for supercritical anhydrous dyeing on the metal mesh layer 4 in different dye cartridges 2, and fix the dye cartridges 2 to the chassis 6. If the chassis 6 The shunt hole 8 that is not available on the top is covered with the rotating mask 7;

[0035] (2) CO heated to a supercritical state under pressure 2 It enters the chassis 6 from the diversion pipeline, and is divided into multiple bundles, which are used to dissolve different kinds of dyes, supercritical CO 2 After passing through each split hole, it reaches each dye cartridge 2 with different dyes, and the air flow passes through the metal mesh layer 4 smoothly, so that the dye is fully in contact with the air flow, and only the dye in the dissolved state ca...

Abstract

The invention provides a supercritical CO2 waterless staining dye pot and a waterless staining method. The supercritical CO2 waterless staining dye pot comprises a dye pot body and is characterized in that the dye pot body comprises at least two dye cylinders and a chassis, wherein each dye cylinder comprises a cylindrical shell and a top cover; the top cover is mounted at the upper end of the cylindrical shell; a metal mesh layer for placing of dyes is arranged at a lower part of the cylindrical shell, and a filter layer for filtering undissolved dyes is arranged at the upper part of the cylindrical shell; diversion holes are formed in the chassis; a rotary blocking piece for blocking the diversion holes is arranged on the bottom surface of the chassis; the lower end of the dye cylinder is mounted at a position of the diversion hole in the top surface of the chassis; inner cavities of the dye cylinders are respectively communicated with corresponding diversion holes. According to the invention, the phenomena of uneven color and staining in a waterless staining process are reduced; purposes that all dyes do not pollute each other and the amount of dye is controllable are achieved.

Description

technical field [0001] The invention belongs to the technical field of novel dyeing, in particular to a supercritical CO 2 An anhydrous dyeing dye kettle and an anhydrous dyeing method. Background technique [0002] In the traditional dyeing process, we usually use water as the main medium. A large number of chemical substances such as dyes and surfactants will have a negative impact on the sustainable development of the environment. In addition, neutralization, sedimentation and other treatments are required for the sewage discharged from dyeing, which requires a lot of manpower and material resources. According to incomplete statistics, the annual water consumption of my country's textile printing and dyeing industry reaches 1.7 billion tons, and the sewage discharge reaches 1.6 billion tons. However, in recent years, there has been a serious shortage of water resources in most parts of our country, especially problems such as sewage discharge have seriously restricted ...
