Multifunctional denim warp dyeing machine

Abstract

The invention provides a multifunctional denim warp dyeing machine, which comprises a to-be-dyed warp rack and a dyed warp reel. A warp pretreatment tank, a warp dyeing groove, a washing tank and a slashing tank are successively arranged between the to-be-dyed warp rack and the dyed warp reel, wherein the warp pretreatment tank is used for removing impurities of warps and washing the warps, the warp dyeing tank is used for dyeing the warps by indigo dyes or sulfur dyes, the washing tank is used for washing the dyed warps, a combined drying barrel, a small colorful dyeing tank and a steaming box are successively disposed between the warp pretreatment tank and the warp dyeing tank, the combined drying barrel is used for colorfully dyeing the warps, and the small colorful dyeing tank dyes the warps by reduced dyes. The problems that when warps are dyed, a color selection range is narrow, color fastness is poor, and the warps cannot be dyed by bright-colored dyes are resolved; after the dyed warps are woven into denim, the characteristics that the warps of the denim are colorful while wefts of the denim are white can be kept; composite dyeing by the aid of the indigo dyes or the sulfur dyes can be realized, and a dyeing effect is good.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a multifunctional denim warp yarn dyeing machine. Background technique [0002] With the development of denim clothing, the share of colored denim in denim dyeing is increasing. At present, most of the colored denim clothing on the market is made of undyed white denim and then passed through a washing factory. Garment dyeing with direct dyes has the following defects: 1. The warp and weft yarns of the denim fabric are dyed at the same time in garment dyeing, which lacks the unique characteristics of denim fabrics that the warp yarns are colored and the weft yarns are white and not dyed; 2. Washing factories directly use The color difference of the dye register is large, and the color between batches is prone to differences; 3. The spandex yarn is easily damaged when the fabric containing spandex yarn in the weft yarn is dyed, and the product scrap rate is high. In order to avoid the def...
