The dyeing machine plays roles of demonstration and leading in a dyeing and finishing equipment industry, and leads development directions of the industry.

Description

technical field [0001] The invention relates to the technical field of dyeing machinery, in particular to an ultra-low liquor ratio gas-liquid split dyeing machine with a built-in gas-liquid spray dyeing system and a cloth lifting system. Background technique [0002] Currently widely used dyeing machines mainly include two types according to the dyeing principle: overflow dyeing machine and air atomization dyeing machine. The overflow dyeing machine has the disadvantages of large bath ratio, high steam consumption, many dyeing and chemical auxiliaries, and long process time, and the dyeing quality also has problems such as creases on the fixed cloth surface and poor tubes. The air atomization dyeing machine adopts the principle of aerodynamics, and uses the air nozzle to atomize and spray the dye solution onto the fabric, so as to solve the various shortcomings of the overflow dyeing machine, and gradually become the mainstream dyeing technology. The nozzle is the core key...

AI Technical Summary

Problems solved by technology

[0004] (1) The air flow needs to atomize the dye liquor in the mixing chamber first, and then blow the fabric through the nozzle to carry out the dyeing at the same time, because the air flow and the dye liquor Inconsistencies in the respective pressures and flow angles before mixing lead to a large amount of turbulent flow when the airflow contacts and atomizes the dye liquor, which wastes a lot of kinetic energy, reduces efficiency, and leads to a sharp increase in energy consumption.

[0005] (2) The air atomization dyeing machine relies on the power of the air flow to pull the fabric forward, requiring high flow and high pressure airflow to pull the fabric, which makes the fan energy consumption high

[0006] (3) The dyeing liquid and the air flow are first atomized and then blown through the nozzle to dye the fabric at the same time. Due to the characteristics of the fabric, the higher the moisture content, the harder it is to fluff and blow off, resulting in the fact that the fabric is often dyed before it is completely fluffy. The process is over, so that the dyeing solution does not penetrate completely, the level dyeing performance is poor, and the color yield is low. To solve this problem, the air atomization dyeing machine can only prolong the dyeing time, increase the amount of auxiliaries and dyes, and blow the cloth to make the cloth fluffy. It is necessary to increase the flow rate and pressure of airflow, dyeing liquor, resulting in an increase in energy consumption and an increase in the total amount of COD emissions;
