Embodiment 1

[0032] Such as Figure 1-2 As shown, the online dyeing equipment of the two colors not synchronously dyed, the online dyeing equipment is a winder with a dyeing unit 2 and a dye solution supply unit 3, and the online dyeing equipment consists of a bobbin winding device 1. Dyeing unit 2, dye solution supply unit 3, package yarn 4, yarn carrier base 5, balloon breaker 6 and equipment base 7, the balloon breaker 6 is fixed on the equipment base 7, the balloon breaker 6 Uniform high-speed axial unwinding tension of the yarn, reduce and prevent loop breakage, and achieve the purpose of improving productivity. The dyeing unit 2 is arranged between the package yarn 4 and the package yarn winding device 1, and the dyeing unit 2 includes 1# dyeing tank 203A and 2# dyeing tank 203B, described 1# dyeing tank 203A is provided with 1# dyeing runner 202A, and described 2# dyeing tank 203B is provided with 2# dyeing runner 202B, and described dye liquor Supply unit 3 comprises 1# dye soluti...

Embodiment 2

[0039] The on-line dyeing process that the two colors are dyed asynchronously comprises the following steps:

[0040] (1) Dye solution configuration: 1% (mass percentage) of reactive red dye and 2% (mass percentage) of reactive blue dye were dissolved in ethanol 30% (mass percentage), water 69.5% (mass percentage), and penetrant 0.5% (mass percentage) system, add 30g / L soda ash, and keep stirring until the dye is completely dissolved.

[0041] (2) Use the peristaltic pump to supply the prepared dye solution to the dyeing tank of the improved loose winder. The 2# dyeing tank is reactive red dye, and the 1# dyeing tank is reactive blue dye. The peristaltic pump slowly adds liquid at a speed of 10 rpm. Carry out loose winding to yarn, the speed of winding machine is 800m / min, the rotating speed of 2# dyeing runner is 30r / min, and the rotating speed of 1# dyeing runner is 15r / min. The dyeing liquid is brought up by the high-speed rotating dyeing wheel, and quickly adheres and pe...

Embodiment 3

[0045] The on-line dyeing process that the two colors are dyed asynchronously comprises the following steps:

[0046] (1) Dye solution configuration: 2% (mass percentage) of reactive blue dye and 2% (mass percentage) of reactive red dye were dissolved in ethanol 20% (mass percentage), water 79% (mass percentage), and penetrant 1% (mass percentage) system, add 40g / L soda ash and stir continuously until the dye is completely dissolved.

[0047] (2) Use the peristaltic pump to supply the prepared dyeing solution to the dyeing tank of the improved loose winder, the 2# dyeing tank is reactive blue dye, and the 1# dyeing tank is reactive red solution. The peristaltic pump slowly adds liquid at a speed of 8 rpm. The flax yarn is loosely wound, the speed of the winding machine is 600m / min, the rotating speed of the 2# dyeing wheel is 40r / min, and the rotating speed of the 1# dyeing wheel is 20r / min. The dyeing liquid is brought up by the high-speed rotating dyeing wheel, and quickly...

Abstract

The invention belongs to the technical field of textile dyeing, and particularly relates to online dyeing equipment and process for asynchronous dyeing of two colors. The on-line dyeing equipment is a winding machine provided with a dyeing unit and a dye liquor supply unit, and is composed of a cone yarn winding device, the dyeing unit, the dye liquor supply unit, cone yarn, a yarn carrying base, an air ring breaker and an equipment base, wherein the dyeing unit comprises a first dye vat and a second dye vat, the dye liquor supply unit controls supply and circulation of dye liquor, the dye liquor is conveyed into the dye vats, during dyeing, the rotating speed and the running speed of a dyeing wheel are adjusted, the dye liquor on the surface of the dyeing wheel is rapidly adhered and permeates into fibers, dye is fixed through steaming treatment and aftertreatment, and finally the dyed yarn distributed with different colors is obtained. According to the process, the production process can be remarkably shortened, the production operation can be simplified, the using amount of dyeing auxiliaries can be reduced, the use coverage of dye types and yarn types is wide, diverse fabric styles and leisure production can be achieved, and the market requirements for small batch and diversification are met.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing, and in particular relates to an on-line dyeing device and process for dyeing two colors asynchronously. Background technique [0002] The production process of yarn-dyed fabric is complicated and the process is cumbersome, especially the dyeing process, which has always had the status quo of high consumption, high pollution and environmental protection pressure. Conventional bobbin dyeing process takes a long time, the process is complicated, the water consumption is large, and only a single full-color yarn can be dyed. At present, the production of section dyed yarn is mainly realized by dyeing of hank yarn, which is cumbersome, time-consuming and labor-intensive. [0003] The invention improves and optimizes the loose winder as a special dyeing equipment, which can realize independent control between ingots and produce colored yarns with different color distributions, which can be singl...
