Continuous pad-steam dyeing loose fiber dyeing process

Abstract

The invention discloses a continuous pad-steam dyeing loose fiber dyeing process. The process includes the steps of pad-leaching dying, steaming, pad-leaching washing, opening and drying. The continuous pad-steam dyeing loose fiber dyeing process can achieve continuous pad-steam dyeing processing.

Description

technical field [0001] The invention relates to the field of textile dyeing and finishing, in particular to a dyeing, padding and steaming continuous loose fiber dyeing process. Background technique [0002] The loose fiber dyeing device in the prior art comprises a paddle dyeing machine, a cold pile unit, a paddle washing machine, an opener and a dryer arranged in sequence. The process flow is: first dyed by a spray dyeing machine, rolled into rolls after dyeing, then hoisted by a hoist and placed in the cold stack room for cold stacking, after the cold stacking is completed, the rolls are unrolled for washing , Opening, drying, packaging and other processes, the processing is carried out intermittently. There are following problems in this kind of loose fiber dyeing process: [0003] 1. In the cold stacking process, it is necessary to form a roll first, and then use a crane to hoist it into the cold stacking room for cold stacking and color fixing for more than 12 hours....

AI Technical Summary

Problems solved by technology

[0003] 1. In the cold stacking process, it is necessary to form a roll first, and then use a crane to lift it into the cold stacking room for cold stacking and color fixing for more than 12 hours. After the cold stacking and color fixing, the rolls will be unrolled. Too much, resulting in low production efficiency and high labor intensity for workers

[0004] 2. In the cold stacking process, it is necessary to establish a professional cold stacking room, which occupies a large area and requires a large investment. It requires a lot of heat energy to ensure constant temperature, and the production and operation costs are high.
