Device and method for cone yarn fixation aftertreatment

Abstract

The invention relates to the technical field of reactive dyeing equipment, in particular to a device for cone yarn fixation aftertreatment. The device comprises a barrel body, a yarn barrel rotating shaft, a yarn barrel and a driving motor. The barrel body is divided into a dehydration chamber and a negative pressure chamber by a partition plate and provided with a water outlet communicated with the lower portion of the dehydration chamber. The yarn barrel rotating shaft is installed in the dehydration chamber, the driving motor is connected with the yarn barrel rotating shaft, the yarn barrel is tubular, through holes are evenly distributed in the outer circle surface of the yarn barrel, the yarn barrel is installed on the yarn barrel rotating shaft, the yarn barrel can be communicated with the negative pressure chamber through the yarn barrel rotating shaft, and the barrel body is provided with a negative pressure device interface communicated with the negative pressure chamber. The device for cone yarn fixation aftertreatment can make the liquid carrying rate of each part uniform after cone yarn fixation, and a fixation effect is improved.

Description

technical field [0001] The invention relates to the technical field of reactive dye dyeing equipment, in particular to a package yarn fixing post-processing device and a cheese fixing post-processing method. Background technique [0002] Reactive dyes, also known as reactive dyes, are a class of dyes that chemically react with fibers during dyeing. Reactive dye molecules contain groups that can chemically react with fibers. When dyeing, the dyes react with the fibers, and form a covalent bond between the two to form a whole, which improves the fastness to washing and rubbing. It is currently widely used in cellulose Dyeing of fibers (cotton, hemp, viscose, tencel, modal, cupro, etc.), protein fibers (wool, soybean fiber, milk fiber, etc.), synthetic fibers (nylon, etc.). Reactive dye molecules include two main components, the parent dye and the active group, and the group that can react with the fiber is called the active group. The parent structure of reactive dyes is gen...

Problems solved by technology

For the existing cheese dehydration device, please refer to the invention patent application with the application number 201510932513.0 and the name "A Kind of Cheese Dehydration Machine". It will cause the liquid-carrying rate of the package far away from the main shaft of the dehydrator to be higher than the liquid-carrying rate of the part close to the main shaft of the dehydrating machine, resulting in uneven color fixation
