Description

Yarn jet dyeing production line and dyeing method thereof Technical Field The invention relates to the technical field of textile dyeing and finishing equipment, in particular to a yarn jet dyeing production line and a dyeing method thereof. Background At present, in the dyeing and finishing industry, the continuous dyeing process of yarns generally adopts indigo and sulfur dyes, and the process generally comprises the following steps of 1, feeding yarns to be dyed, 2, padding indigo or sulfur dye liquor, 3, oxidizing ventilation, 4, washing, 5, acid neutralization, 6, washing, 7, drying, 8, sizing, 9, drying, 10, storing yarns and 11, doffing by a reel. Based on the above process, the field of continuous dyeing of yarns is generally divided into two modes of pad dyeing and space dyeing, wherein the pad dyeing is used for continuously dyeing the yarns into one color, and the space dyeing is used for representing one section with one single color and multiple colors. However, it is difficult to form multicolor patterns composed of three primary colors by computer intelligent typesetting, and it is hoped that the preset flower type patterns can be obtained by warp modification arrangement, preferably organization specification and weft yarns on the basis. Disclosure of Invention In order to obtain a preset pattern, based on a mode in a background process, a working solution storage tank is arranged for uniform dyeing, the surface area of a storage tank is too large, so that heat loss in the practical application process is high, energy consumption required by heating is always large and not reduced, an open dyeing tank and the outside are exposed and are in contact with oxygen, the invalid decomposition of a reducing agent is large, the decomposition rate is difficult to control, meanwhile, the storage amount of the working solution is large, the control difficulty of the supplementing flow of the mother solution is large, the color control difficulty is increased due to low replacement freshness of the dye solution, the cost of dye replacement of practical manufacturers is high due to the fact that the dye tank with large capacity (about 3000 liters of the dyeing working solution is arranged in each dyeing tank), the floating color is largely dropped when the dye is low in the dyeing rate of the dye washing water, the sewage chromaticity is high, the treatment difficulty is high, and the subsequent sewage treatment cost is high. Therefore, in order to overcome the defects in the prior art, the invention aims to provide a yarn jet dyeing production line and a dyeing method thereof, which can effectively alleviate or solve the problems.
