Description

Technical Field

[0001] The invention relates to the technical field of printing and dyeing equipment, in particular to a dyeing vat. Background Art

[0002] Dyeing refers to the process of dyeing the fiber from the dye liquor and forming a uniform, strong and bright color on the fiber. The chemical composition of various fibers is different, and the applicable dyes are also different. Cotton fabrics are mainly dyed with reactive dyes. Polyester fabrics are mainly dyed with dispersed materials, and the commonly used dyeing methods are high temperature method, carrier method and hot melt method. Modified polyester fabrics with anionic groups can also be dyed with cationic dyes to obtain rich colors. Nylon fabrics are mainly dyed with acid dyes, and can also be dyed with acid mordant dyes, disperse dyes and some direct dyes at near boiling point. Acrylic fabrics are mainly dyed with cationic dyes or disperse dyes. Vinylon fabrics are mainly dyed with vat, sulphur and direct dyes. Polypropylene fabrics are difficult to dye, and some can be dyed with disperse dyes or acid dyes after denaturation treatment. Acetate fabrics are mainly dyed with disperse dyes, and sometimes with insoluble azo dyes.

[0003] Fabric dyeing is generally carried out in a dye vat. When dyeing, the dye must be prepared first, then the dye is added to the dye vat and water is added to stir evenly, and then the fabric is put into the dye vat for dye bath. The fabric will pass through the dye liquid, thereby contacting and exchanging with the dye liquid, so that the dye adheres to the fabric. During the dyeing process, the staff also needs to observe the dyeing condition of the fabric in real time until the dyeing requirements are met.

[0004] At present, the existing dyeing vats only serve to hold dye liquor and immerse fabrics. Most of the steps in the fabric dyeing process still require manual operation, and the dyeing efficiency is low. First, the step of adding dyes requires manual operation. The prepared dyes need to be added to the dyeing vat and stirred until the dyes are dissolved and dispersed. The operation is troublesome, time-consuming and laborious. Secondly, since there are no samples in advance, the dyeing process requires manual continuous observation of the vat and real-time observation of the dyeing of the fabric to avoid affecting the dyeing quality due to dye problems. The dyeing vat is large and the amount of dye liquor is large. In order to ensure clear observation, the dye needs to be frequently stirred to expose the fabric. Therefore, the operation is time-consuming and laborious. Finally, after dyeing, the lid needs to be opened manually to take out the fabric. The vat lid is heavy, so the operation is laborious.

A small piece of sample fabric can be immersed in the sample dye vat 2 for dyeing. During the dyeing process, the staff can judge whether there is a problem with the dye by observing the dyeing condition of the sample fabric in the sample dye vat 2. If there is no problem with the dye, the infusion system can be used to extract the dye solution in the sample dye vat 2 and transport it to the inside of the dyeing main vat 1. Since the dyes used are the same, the dye bath environments inside the sample dye vat 2 and the dyeing main vat 1 are the same. On the basis that the dyeing of the sample fabric in the sample dye vat 2 meets the standards, the dyeing quality of the authentic fabric in the dyeing main vat 1 can be guaranteed. Since the sample dye vat 2 is small and the amount of dye used is small, the dyeing condition of the sample fabric can be clearly observed without stirring the dye, thereby choosing whether to adjust the dye. The operation is time-saving and labor-saving, and can reduce the waste of dye and fabric, thereby reducing costs. Through this series of settings, the steps of manual operation are reduced, the degree of automation is high, and the dyeing efficiency is high.

The arm 21 rotates upward, so that the cylinder cover 19 can be lifted up, thereby realizing the operation of opening the cylinder cover 19. After taking out the fabric, the rotating arm 21 can be driven by the power assembly to return to its original position downward, thereby realizing the closing of the cylinder cover 19. The operation is relatively convenient and simple. The power assembly includes a cylinder 22 rotatably connected to the bracket 20, and the piston rod 23 of the cylinder 22 is hinged to the rotating arm 21.
