Matching device for dyeing machine and cloth dyeing method

Abstract

The invention provides a matching device for a dyeing machine. The matching device can simply realize foam inhibiting and defoaming effects by utilizing circulation of dye solution inside the dyeing machine. The matching device comprises a spraying system which is used for utilizing the dye solution inside the dyeing machine and spraying the dye solution on the position where the cloth is not operated smoothly due to existence of foam. By utilizing the matching device provided by the invention, the dye solution is continuously sprayed on the foam in the vat by a sprayer, thus achieving the foam inhibiting and defoaming effects. The invention provides a cloth dyeing method. By adopting the method, the foam inhibiting and defoaming effects can be simply realized by utilizing circulation of the dye solution inside the dyeing machine. Compared with the traditional devices and methods utilizing the defoaming agents for foam inhibiting and defoaming, the device and method provided by the invention have the following beneficial effects: the foam inhibiting and defoaming effects are achieved by utilizing the physical effect generated by circularly spraying the liquid inside the dye vat; the operation cost is lower; the structure is simple; the practicability is strong; the effect is obvious; other defoaming agents are unnecessary to be added, thus reducing the environmental pollution;and the device and the method can be popularized and applied to all kinds of cloth dyeing machines.

Description

technical field [0001] The invention relates to a matching device for a dyeing machine, in particular to a matching device for a dyeing machine which uses jetting of dye liquor to propel cloth. The invention also relates to a cloth dyeing method, in particular to a method capable of suppressing and defoaming during the cloth dyeing process. Background technique [0002] During the dyeing process, the fabric must circulate rapidly in the dye vat so that it can fully contact with the dye solution in the dye vat to achieve the pre-dyeing or dyeing function. In the current common dyeing machine, the nozzle is used to spray the dye solution to drive the cloth circulation. [0003] The structure of a conventional dyeing machine that utilizes the injection of dye liquor to propel cloth is as follows: figure 1 As shown, it includes dye vat 1, cloth pipe 2, dye liquid circulation pipeline 3, nozzle 4, and cloth lifting roller 5. Dye liquid 6 is installed in the dye vat, and cloth 7...

Problems solved by technology

However, while the defoamer defoams in the tank, it also brings quality risks such as new oil stains to the fabric and the inside of the tank, and causes environmental pollution or increases the burden on sewage treatment when discharged.

The selection of low-foaming or non-foaming additives increases the cost of dyeing and finishing virtually.
