How to dye the Yarn Package Dyeing Machine

1 pine cone

The raw yarn is wound into a "loose bobbin" suitable for bobbin dyeing. This process is generally called a loose bobbin. The winding density of a bobbin used for dyeing is much lower than that of a general bobbin. Therefore, a "loose bobbin" is required. ".

2 cages

The cage must be uniform and tight. The fiber loading amount should be appropriate. If it is lower than the reasonable loading amount, it is easy to form an irregular water flow channel, that is, a "short circuit" phenomenon; The greater the penetration of water, the weaker the weak.

3 dyeing

The biggest feature of cheese dyeing is that the dyed material is fixed and the winding is tight. The normal dyeing process is realized by the forced circulation of the dye liquor in the yarn by the main pump. The circulation of the dye liquor not only accelerates the diffusion of the dye, but also conducts heat.

4 drying

Drying is as important as cheese preparation and dyeing. This step solves the problem of color difference and uniform humidity inside and outside the cheese. After the cheese is dyed, it is discharged out of the vat. After discharging, we need to dehydrate the dyed yarn and then dry it. For processing, we generally use hot air to dry. The drying time and temperature also have a certain effect on the color difference of the yarn.

5 inverted tube

The difference between the rewinding tube here and the loose tube in front is that it is a tight rewinding tube, which is convenient for weaving fabrics in the future.
