Yarn surface dyeing device

Abstract

The invention discloses a yarn surface dyeing device, and belongs to the technical field of textile machinery. The yarn surface dyeing device comprises at least one coloring mechanism, the coloring mechanism comprises a first liquid feeding tank and a second liquid feeding tank, a first rotating wheel is arranged in the first liquid feeding tank, and a second rotating wheel is arranged in the second liquid feeding tank; the first rotating wheel is in contact with working liquid arranged in the first liquid feeding tank, the second rotating wheel is in contact with working liquid arranged in the second liquid feeding tank, and the first liquid feeding tank and the second liquid feeding tank are both communicated with an automatic liquid feeding device. The number of the automatic liquid supply device is at least one. The method can be used for coloring the surfaces of the cotton yarns and the cotton blended yarns, does not waste any dyestuff and auxiliaries, does not discharge sewage, basically does not need water, only needs little electricity and steam, has the comprehensive energy consumption cost of per ton of yarns being about 1 / 10 of that of the traditional dip dyeing method, and is green, environment-friendly and low-carbon; yarns with high-count color spinning effects can be produced, and market requirements are met.

Description

technical field [0001] The invention relates to a yarn surface dyeing device, which belongs to the technical field of textile machinery. Background technique [0002] There are two conventional ways of dyeing cotton yarn and cotton blended yarn for textile use: dip dyeing method and spray dyeing method. The exhaust dyeing method is to twist the yarn into skein yarn or bobbin yarn or warp beam yarn. By dipping the yarn in the dyeing solution, the yarn can be changed from natural color to various colors through the action of saline and alkali and dyes and fibers. Yarn, dyed yarn is evenly dyed, and under normal circumstances, it will not produce color spots and flower spots. The spray dyeing method is to color the surface of the yarn by spraying dye or other working liquid with color-fixing components on the surface of the yarn, which can be made into a space dyeing style. [0003] Due to the needs of market customers for dyeing product innovation and differentiated styles, ...

Problems solved by technology

Moreover, the exhaust dyeing method consumes a lot of dyes, auxiliaries, water, electricity, steam, etc. for yarn dyeing, and also produces a large amount of waste water; although the spray dyeing method consumes less energy than the dip dyeing method, the style of the yarn is very high. Dyeing, there is a limit to the length of the dyed yarn (normally more than 1CM), and it cannot achieve the fancy yarn effect obtained by blending cotton fibers after dyeing

[0005] At present, some textile companies make gray yarn (fancy yarn) by dyeing cotton fibers first, then blending colored fibers, and then processing them in cotton spinning mills to obtain fancy yarns. There will be a certain loss in length and length, and it can only process coarse-count yarns, and cannot produce high-count yarns (such as 60-100 single yarns); and there has always been a demand for high-count yarn-dyed yarns in the market, but there is no way to produce, this is the technical bottleneck
