Abstract

The invention relates to the field of printing and dyeing processes, in particular to a device and process for reducing dyeing chromatic aberration, and the chromatic aberration of dyes in a pluralityof dyeing cylinders can be rapidly reduced. The device for reducing dyeing chromatic aberration comprises a plurality of dyeing cylinders and a main pipeline, wherein the plurality of dyeing cylinders are provided with drainage pipes at the bottom, and a liquid inlet pipe is arranged at a side surface or the top of each dyeing cylinder, one end of the main pipe is connected to all the drainage pipes, the other end of the main pipe is connected to all the liquid inlet pipes, and the main pipeline is provided with a main circulation pump. According to the process for reducing dyeing chromatic aberration, the dyes in the plurality of dyeing cylinders are circulated by using a parallel method so as to reduce the dyeing chromatic aberration.

Description

technical field [0001] The invention relates to the field of printing and dyeing technology, in particular to a device and a technology for reducing color difference in dyeing. Background technique [0002] During the dyeing process of yarn or fabric, due to the limited capacity of the same dyeing vat, the same batch of products must be dispersed into several different dyeing vats for dyeing. The concentration of dyes in different dyeing vats, air pressure and temperature will affect the final color of the dye. , causing color difference in the same batch of products. [0003] In order to overcome the color difference between different dyeing vats, the dyeing method of combined vats appeared. Connecting vats is to connect the dyeing vats in series, so that the dyes can be mixed between different dyeing vats to reduce the color difference. However, most of the current combined vats are two-connected vats. Due to the series structure of the combined vats, when the number of ...
