1 loose tube
The yarn is wound into a "loose bobbin" suitable for bobbin dyeing. This process is generally called loose bobbin. The winding density of the bobbin used for dyeing is much lower than that of general bobbins. ".
2 Cage
The cage should be uniform and tight. The loading amount of fibers should be appropriate. If it is lower than the reasonable loading amount, it is easy to form irregular water flow channels, that is, the phenomenon of "short circuit"; once it occurs, it will become more and more obvious, and will gradually make the whole cage. The larger the place where the water flow penetrates the greater, the weaker the weak place.
3 Dyeing
The biggest feature of cheese dyeing is that the dyed object is fixed and tightly wound. The normal progress of dyeing is realized by the forced circulation of the dye liquor in the yarn by the main pump. The circulation of dye liquor not only accelerates the diffusion of dye, but also conducts heat.
4 Drying
Drying is as important as package preparation and dyeing. This step solves the problem of color difference inside and outside the package and uniform humidity. After the package is dyed, it is released from the cylinder. After the package is released, we need to dehydrate the dyed yarn and then dry it. Processing, generally we use hot air drying. The drying time and temperature also have a certain influence on the color difference of the yarn.
5 rewind
The difference between the rewinding here and the previous slackening is that it is a tight rewinding, which is convenient for weaving fabrics in the future.
