Dyeing device for textile yarn

Abstract

The invention discloses a dyeing device for textile yarn. The dyeing device comprises a high-temperature expansion kettle and a high-temperature dyeing kettle which are fixedly connected to the side wall of the upper end of a mounting table. Distilled water is arranged in the high-temperature expansion kettle, and dye is arranged in the high-temperature dyeing kettle. High-temperature expansion isadopted, thus yarn fibers can be heated to expand and loosen, a good level dyeing effect can be obtained when the yarn fibers are dyed, and the tension of the yarn can be eliminated; and high-temperature dyeing is adopted, thus the yarn fibers are further heated to expand and loosen, a good level dyeing effect is obtained, dye particles can be continuously dissolved and thinned and rapidly permeate and diffuse into the inner layers of the yarn fibers, meanwhile, dyeing, air-drying, re-dyeing, re-air-drying and double dyeing and air-drying can be achieved, the yarn dyeing effect is very good,high-temperature expansion and dyeing and air-drying processes can be simultaneously achieved for nine pieces of yarn, and therefore the dyeing efficiency is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of textile machinery and equipment for yarn dyeing, in particular to a dyeing device for textile yarn. Background technique [0002] Yarn is a kind of textile, processed into a certain fineness product with various textile fibers, used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short fiber yarn, continuous filament, etc., in the textile industry Among them, yarn dyeing is a dyeing process with yarn as the object, mainly including warp beam dyeing, hank dyeing, cheese dyeing, compressed cheese dyeing and filling dyeing. [0003] At present, when dyeing polyester and other yarns with disperse dyes, the molecular structure of the yarns is tightly arranged and the fiber pores are extremely small. It is difficult for the dye molecules to enter the fiber core layer, so the dyeing effect is not good, and some existing textile yarns are used The dyeing device cannot perform h...

Problems solved by technology

[0003] At present, when dyeing polyester and other yarns with disperse dyes, due to the tight molecular structure of the yarns and the extremely small fiber pores, it is difficult for the dye molecules to enter the fiber core layer, so the dyeing effect is not good, and some existing textile yarns are used The dyeing device cannot perform high-temperature puffing and high-temperature dyeing processes on the yarn, and the dyeing effect is not good. At the same time, the yarn is only dyed once, and the dyeing effect is not good. It can only dye a single yarn, and the dyeing efficiency is low. For this reason we have proposed a kind of dyeing device for textile yarn to solve the above problems
