Dye vat structure of normal-temperature normal-pressure jig dyeing machine

Abstract

The invention relates to the technical field of textile, and discloses a dye vat structure of a normal-temperature normal-pressure jig dyeing machine. The dye vat structure comprises a dye vat and a standard dye vat, wherein the dye vat and the standard dye vat are in communication with a communicating pipe, a semipermeable membrane is arranged in the communicating pipe, two electric sheets are fixedly arranged on the inner wall of the standard dye vat, a dye liquor hopper is arranged above the standard dye vat, and a control valve is arranged between an outlet of the dye liquor hopper and aninlet of the standard dye vat. According to the dye vat structure, the concentration of dye liquor in the dye vat is balanced through the permeation characteristic of the semipermeable membrane and the dye liquor concentration in the standard dye vat, and the opening and closing of the control valve and the size of the opening are controlled according to the dye liquor concentration in the standard dye vat, so that the dye liquor concentration in the dye vat and the standard dye vat is controlled to tend to the standard dye liquor concentration and keep dynamic balance, color difference between the head and the tail of the cloth due to large concentration difference of the dye liquor in a dyeing process is avoided, and the dyeing quality is improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a dyeing vat structure of a normal temperature and normal pressure jigger. Background technique [0002] Open-width jigging of fabrics is a relatively long-established dyeing process, which is very suitable for satin-like fabrics that are easy to crepe. There are many varieties of fabrics suitable for jigging, such as cotton, polyester, silk and blended or interwoven woven fabrics. It is especially suitable for jig dyeing for brocade, silk and satin crepe-friendly fabrics. Jiggers can be used for desizing, scouring, bleaching, dyeing and washing processes. During the dyeing process, the concentration of the dye solution in the dye vat gradually decreases, and the concentration of the dye solution decreases as it goes to the back. Therefore, the chromaticity of the fabric dyed first and dyed later will be different, and the defect of "head and tail color difference" will appear...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the use of the existing dye vats proposed in the background technology, the present invention provides a dye vat structure of a normal temperature and pressure dyeing jigger, which has the advantage of reducing excessive changes in the concentration of the dye solution, and solves the problems in the above background technology. The problem of the head and tail color difference of the cloth caused by the reduction of the concentration of the dye solution proposed
