Description

Supercritical low-temperature yarn barrel dyeing cylinder

Technical Field

The invention relates to the technical field of yarn barrel dyeing, in particular to a supercritical low-temperature yarn barrel dyeing vat.

Background

The traditional yarn dyeing process is to wind the yarn to be dyed on a bobbin, immerse the yarn into a dye vat filled with dye after a certain amount of crisp yarn loosening, heat and stand the dye vat for a period of time, so that the dye is immersed into the yarn to obtain the yarn with the required color. But need guarantee certain immersion time during through the liquid chemistry course of working just can guarantee that the dyestuff can immerse in the yarn completely to the time that relatively needs is longer, need consume a large amount of water resources and chemical simultaneously in the liquid chemistry course of working, thereby produces the coloured waste water of a large amount of high concentration, has caused serious destruction to surrounding environment and waters. To solve this problem, supercritical carbon dioxide plus powdered dyes are now used instead of traditional liquid chemical dyes. The carbon dioxide is pressurized to 73atm, so that the density of the carbon dioxide is changed and is close to the density of the carbon dioxide and liquid, the dye and the carbon dioxide are mixed and sprayed on the yarn, the yarn can be dyed, a large amount of water is not needed during dyeing, and no redundant wastewater is generated after dyeing is finished, so that the dyeing mode is environment-friendly. However, some domestic supercritical dyeing equipment is still in small and medium-sized equipment limited to laboratory scale, and cannot dye a large batch of yarns.
