Description

Dyeing device for colored spun yarn processing

Technical Field

The invention relates to the technical field of spinning processing, in particular to a dyeing device for colored spun yarn processing.

Background

The colored spun yarn is characterized in that the fiber is dyed into colored fiber, and then the fiber with two or more different colors is fully mixed to be spun into the yarn with unique color mixing effect. Dyeing is an important step in the processing of spun yarns, and specific dyeing methods come in many forms, such as hank dyeing, cheese dyeing, warp beam dyeing, and the like.

The cheese dyeing is to place the wound cylindrical yarn in a corresponding dyeing barrel and dye the yarn at high temperature by dye, however, in the traditional cheese dyeing method, when the dyeing is finished, the dye liquid in an internal spraying state can directly splash out at the moment of opening the barrel cover, so that the operating environment is easily polluted, and meanwhile, the operation of workers is not convenient; meanwhile, when the centrally-arranged tubular yarns are hoisted, the through holes in the hoisting rings are generally large in order to facilitate hanging of the hooks, but in the process of taking out and placing the tubular yarns, due to the fact that the tubular yarns are not well limited, shaking is easy to occur, the tubular yarns are not beneficial to the taking and placing process, and particularly when the tubular yarns are collided by the outside, the tubular yarns are more prone to shaking and even falling off; in addition, in the actual dyeing process, the dyed tubular yarns are easy to deviate in the arrangement process due to the fact that the dyed tubular yarns are subjected to showering of dyeing liquid for a long time, and the dyeing effect is affected if the yarns directly contact the inner wall of the dyeing barrel.
