AI Technical Summary

Problems solved by technology

[0003] The existing method of dyeing blended fabrics consumes a lot of energy and causes serious pollution. The water consumption per ton of fabric in most dyeing factories is above 1:100
Most of the dyeing process adopts the intermittent production of dyeing machines from pretreatment to soft finishing. The liquor ratio is about 1:80, and the technology is backward. Large amount of repair, more water consumption; more caustic soda used, high COD of wastewater, sewage treatment can not meet the discharge standards

Abstract

The invention relates to a high-efficiency short-process dyeing process. The dyeing process includes: (1), pretreating; (2), presetting blank cloth; (3), performing reductive cleaning; (4), designing a dyeing auxiliary formulation; (5), dyeing; (6), performing afterfinish wet rapid-steaming. A two-bath method is adopted and includes: dyeing wool fiber: disposing blended fabric in a dyeing container, adding a dyeing auxiliary obtained in the step (4) and dye into the dyeing container at normal temperature to obtain dyed wool fiber; dyeing polylactic acid fiber: disposing a bucket with the blended fabric into the dyeing container, adding the dyeing auxiliary obtained in the step (4), and glacial acetic acid and a dye fixing agent to obtain dyed polylactic acid fiber. The high-efficiency short-process dyeing process has the advantages of being effective in water saving and pollution reducing and high in color fastness.

Description

Technical field [0001] The invention relates to the field of fabric dyeing, in particular to a high-efficiency short-flow dyeing process.
