Description

Salt and alkali adding dyeing device

Technical Field

The utility model relates to a fabrics dyeing equipment field especially relates to a salt and alkali dyeing apparatus.

Background

Dyeing can be mainly classified into ready-made clothes dyeing, fabric dyeing (main extension fabric dyeing, knitted fabric dyeing and non-woven material dyeing), yarn dyeing (which can be classified into hank yarn dyeing, cheese yarn dyeing, warp beam yarn dyeing and continuous warp yarn dyeing) and loose fiber dyeing.

According to different contact modes of dyes and fabrics (dyeing process), the dyeing method can be divided into dip dyeing and pad dyeing.

The dip dyeing is a dyeing method for uniformly dyeing textiles with dyes by dipping a fabric to be dyed in a dyeing solution and circulating the dyeing solution and relatively moving the fabric to be dyed. During dip dyeing, the dye and the dyeing material can be circulated simultaneously or in a single circulation manner; the dip dyeing equipment is simple, easy to operate and wide in adaptability, and is particularly suitable for dyeing loose fibers, yarns, knitted fabrics, wool fabrics and other dyeing objects which cannot bear tension or rolling. The dip dyeing is intermittent production, has low labor production efficiency and is suitable for small-batch and multi-variety production;

the pad dyeing is that after the open width fabric is dipped in the dye liquor for a short time, the fabric is rolled by a press roll, the dye liquor is squeezed into the fiber and the gaps of the fabric tissue, and the redundant dye liquor is removed, so that the dye is uniformly distributed on the fabric. The fabric after padding the dye is treated by steaming or baking and the like to finish the diffusion and fixation of the dye on the fiber. Pad dyeing is mainly used for dyeing fabrics.

The invention patent with Chinese patent application number 202010822312.6 discloses a dyeing device for cloth, which belongs to the technical field of cloth dyeing and comprises: the dyeing box comprises a dye box body, wherein the bottom of the dye box body is connected with a circulating box body through a connecting piece, dye liquid for dyeing cloth is respectively placed in the dye box body and the circulating box body, one side of the dye box body is connected with the corresponding side face of the circulating box body through a second transmission pipe body, the other side of the dye box body is connected with the corresponding side face of the circulating box body through a first transmission pipe body, a first pump body is arranged on the first transmission pipe body, a feeding pipe for feeding is connected onto the second transmission pipe body, aeration components are respectively arranged in the dye box body and the circulating box body, and the device solves the problems of uneven dyeing of the cloth and folds in the existing cloth dyeing process. However, the existing dyeing device still has the technical problems of uneven dyeing and dye deposition and accumulation on the cloth, and further the dye uptake is low.

SUMMERY OF THE UTILITY MODEL

Therefore, to foretell problem, the utility model provides a salt and alkali dyeing apparatus has solved the technical problem that current dyeing apparatus dyeing is inhomogeneous and the dye uptake is low.

In order to achieve the above purpose, the utility model adopts the following technical proposal: the utility model provides a salt and alkali adding dyeing apparatus, includes the dyestuff box, the dyestuff box is the tetragonal structure, be provided with one uncovered on the dyestuff box upper surface, uncovered upper cover is equipped with an apron, be provided with feed chute and blown down tank on the apron, be provided with the dyeing cavity in the dyestuff box, the dyeing cavity with uncovered link up each other, be provided with feed roller, first transfer roller, second transfer roller and blown down roller in the dyeing cavity, be provided with at least one reinforced shower nozzle on the inside wall of dyeing cavity, the blown down roller right side is provided with first flitch of scraping, first scrape the flitch support in the outer peripheral surface of blown down roller, the groove of blown down tank is provided with the second along and scrapes the flitch.

Furthermore, the feed chute and the discharge chute are both strip-shaped chute bodies, and the shapes and the sizes of the feed chute and the discharge chute are the same.

Further, an observation window is arranged on the cover plate and is arranged between the feeding chute and the discharging chute, and transparent glass covers the observation window.

Further, the feeding roller and the second conveying roller are in the same horizontal plane.

Further, the first conveying roller and the discharging roller are positioned on the same horizontal plane.

Furthermore, a plurality of hemispherical bulges are uniformly arranged on the outer circumferential surface of the feeding roller.

Further, rubber layers are arranged on the first scraping plate and the second scraping plate.

By adopting the technical scheme, the beneficial effects of the utility model are that:

1. the utility model discloses a be provided with first transfer roller and second transfer roller, the effect of the two can pull the cloth in the dyeing cavity, makes it be in the tiling state, and then can make the dyestuff more even contact with the cloth, through being provided with the dyestuff shower nozzle, can add the auxiliary material at any time in the process of dip-dyeing the cloth, through adding saline-alkali in the dip-dyeing process, its principle is because there is anion group in the reactive dye molecule, and cotton and cellulose fiber have the negative charge; the reactive dye not only reacts with the fiber, but also reacts with water to be hydrolyzed, so that a large amount of inorganic salt is added during dyeing of the reactive dye, the effect of the inorganic salt is to overcome charge rejection firmly, the dye uptake rate is improved, and the hydrolysis of the dye can be reduced; the first scraping plate and the second scraping plate can scrape the front surface and the back surface of the cloth in the cloth dyeing process, so that deposited dye is prevented from being accumulated on the cloth; meanwhile, anhydrous sodium sulphate or alkaline agent is frequently used in the dyeing process of the existing knitted fabric, so that the hue of the colored light of the dyed fabric is unstable, the dosage can be controlled at any time through a dye nozzle, the stability of the hue and the colored light of the dyed fabric can be good, and the waste of auxiliary agents caused by small dosage, poor effect and large dosage can be avoided.

2. Through being provided with observation window, the observation window upper cover is equipped with transparent glass, makes things convenient for the staff can directly observe the state of dyeing in the cavity of dyeing and then can make corresponding adjustment in real time from the outside.

3. The feeding roller and the second conveying roller are located on the same horizontal plane, the discharging roller and the first conveying roller are located on the same horizontal plane, the structure can improve the stability of the cloth in the transmission dip-dyeing process, and the probability that the cloth deforms due to pulling can be reduced.

4. The outer circumferential surface of the feeding roller is provided with the hemispherical protrusions, and the hemispherical protrusions can smooth cloth and cannot damage the fabric.

5. All be provided with the rubber layer on first scraping flitch and the second scraping flitch, the setting on rubber layer can promote the efficiency of scraping the material and avoid injuring the surface of surface fabric simultaneously.
