Description

Technical Field

[0001] The utility model relates to the technical field of alkali reduction low temperature dyeing, in particular to alkali reduction low temperature dyeing equipment for polyester fabrics. Background Art

[0002] Alkali reduction low temperature dyeing equipment is a kind of equipment used for textile dyeing. It adopts alkali reduction treatment and low temperature dyeing technology, which can dye at a lower temperature, thereby reducing energy consumption and environmental pollution.

[0003] For example, the authorization announcement number CN106835739B discloses a low-temperature dyeing method for polyester fabrics, which first uses low-temperature plasma to pretreat the polyester fabric to increase the fiber surface roughness and improve the hydrophilicity of the polyester fabric; then uses 2,6-dihydroxyterephthalic acid as a carrier to perform carrier dyeing, and during the dyeing process, adds a low-temperature dyeing auxiliary to increase the solubility of disperse dyes and promote the adsorption of disperse dyes on the fabric surface; and at the same time, adds organic ester compounds to adjust the pH value of the dye bath. The color depth and dyeing fastness of the obtained dyed fabric are comparable to those of traditional high-temperature and high-pressure dyed fabrics.
