Benefits of technology

In this new way that makes it easier for people who are trying to make clothes look better by giving them their colors more shiny than before they took off because we didn't have any problem doing anything like dying things properly. It saves money compared to previous methods but still produces good results at lower cost. Additionally, there will be fewer chemical waste products produced when producing these fabrics due to less pollution caused from conventional ways such as rinsings and laundering agents used throughout our country.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the removal of colored stains from fabric during chemical mechanical polishing or other types of finishing operations by developing methods that can effectively remove these stain without requiring excessive amounts of materials such as hydrogen sulfur dioxide.

Embodiment Construction

[0031] Such as figure 1 As shown, during the dyeing and cooling process, the high-temperature dyeing residue is discharged under high pressure, and the heat conduction of the residue is used to heat the water injected into the dyeing vat, and the discharged dyeing residue can reduce the temperature to 70°C and discharge it at once. .

[0032] The above-mentioned thermal energy conduction process using residual liquid is realized by using a heat exchanger;

[0033] Such as figure 2 As shown, in this embodiment, the heat exchanger is composed of several water inlet plates 100 and water outlet plates 200;

[0034] The plurality of water inlet plates 100 and the water outlet plates 200 are arranged at intervals; the water inlet plates 100 and the water outlet plates 200 are installed in the middle of the fixed compression plate and the movable compression plate in a superimposed form, and then tightened with tightening bolts.

[0035] The water outlet plate 200 is provided with

Abstract

The invention provides a high-efficiency and environmental-protection dyeing post-processing method of a medium or dark terylene knitted fabric. The method is characterized in that high-temperature dyeing raffinate is discharged under a high pressure in the dyeing and cooling process, heat energy conduction of the raffinate is used to make clear water injected to a dye vat insulated and heated, and the discharged dyeing raffinate is discharged after being cooled to 70 DEG C or less, wherein the heat energy conduction of the raffinate is realized through a heat exchanger; the heat exchanger comprises a water inlet assembly and a water outlet assembly; the water inlet assembly and the water outlet assembly are arranged at intervals; and a swiveling channel is arranged in the water outlet assembly. The above environmental-protection and low-carbon cleaning method reaches the dyeing effect (such as color fastness to water washing and bleeding) of traditional technologies, and has the advantages of time saving, increase of the production efficiency, energy saving and environmental protection.
