Embodiment 1

[0027] In this example, see figure 1 and figure 2 , a device for continuous dyeing using foam wet steaming, mainly includes a steam box and a fabric delivery device, the fabric delivery device is mainly composed of a series of rubber rollers, and the steam box mainly includes a box body 7 and several synchronously rotating cloth guide rollers 14. The fabric dyed by the wet method enters the cloth inlet 10 of the steam box, and after steaming and fixing the color in the steam box, it comes out from the cloth outlet 11 of the steam box to complete the dyeing process of the fabric; continuous dyeing by foam wet steaming The device also includes a foam application device and a suction device.

[0028] The foam application device is mainly composed of a height-limiting plate 4 and a series of spray guns 2. The muzzles of a series of spray guns 2 face the surface of the fabric. The muzzle arrangement extension direction of the series of spray guns 2 is kept perpendicular to the f...

Embodiment 2

[0056] This embodiment is basically the same as Embodiment 1, especially in that:

[0057] In this embodiment, by adjusting the amount of foam applied to the spray gun 2, the position of the foam height limiter 4, the strength of the suction wind of the suction device, and the formula of the foaming solution containing the color fixing agent and the dye, one side of the fabric can be made Any one of three different dyeing processes in coloring, front and back yin and yang coloring and front and back same color coloring. Cotton fabrics with different coloring effects can be dyed by using this device for dyeing processing, and at the same time have high soaping fastness and rubbing fastness, which can meet the needs of wearing performance. Dyeing is carried out by using the wet-steaming dyeing device of reactive dyes in this embodiment. The liquid-carrying rate of the fabric before steaming is as low as 15-35%, which is suitable for dyeing cotton fabrics with reactive dyes, and ...

Abstract

The invention provides a device for continuous dyeing through bubble wet steaming, and belongs to the field of textile dyeing and finishing. The device mainly comprises a bubble applying device, a suction device, a steaming box and a cloth conveying device. The bubble applying device mainly comprises a plurality of spraying guns and a height-limiting plate, and the spraying guns are transversely uniformly arranged along the cloth width; the suction device mainly comprises an inverted suction hood and a control valve; the steaming box mainly comprises a box body and a plurality of cloth guide rollers which rotate synchronously. When dyeing is conducted by using the device, pickup of a fabric obtained before steaming is low to 15-35%, the device is suitable for dyeing cotton fabrics with reactive dyes, the situation that after a high-pickup fabric enters a steaming box, the steaming fixation conditions largely fluctuate is avoided, the fixation rate of the reactive dyes is improved, andcotton fabrics with different dyeing effects can be obtained by adjusting the device and a dyeing process.

Description

technical field [0001] The invention relates to a fabric dyeing device, in particular to a fabric continuous dyeing device, which is applied in the technical field of textile dyeing and finishing. Background technique [0002] Reactive dyes are a class of dyes widely used in cotton fabric dyeing. It has the advantages of complete color spectrum, bright color and excellent wet fastness. Therefore, reactive dyes are widely used in the dyeing of cotton fabrics. Studies have shown that when the liquid carrying rate of cotton fabrics drops to about 30% and that of viscose fabrics drops to about 35%, the moisture on the fabrics at this time is basically bound water and chemically bound water, and there is little free water. It can not only ensure that the fiber channels are filled with water, but also facilitate the dissolution and diffusion of dyes in the channels, and the adsorption and fixation of fibers, and can greatly reduce the hydrolysis of dyes. Therefore, it is the pursu...
