Factors affecting dyeing uniformity of GYS-L-F Serial Liquid Flow &Jet HT Dyeing Machine

1. Dye circulation system
The dyeing machine relies on liquid jet to make the dye fully contact with the fabric. If the power of the main pump is unstable or the design of the circulation pipeline is unreasonable, the dye will flow unevenly in the machine. For example, local blockage or excessive bending in the pipeline will cause the dye to flow too fast or too slow in some areas, which will affect the contact time and degree between different parts of the fabric and the dye, and finally lead to uneven dyeing.
2. Fabric loading and placement method
If the fabric is overloaded in the dyeing machine, the fabrics squeeze each other, which will hinder the penetration of the dye and prevent the fabric inside from fully contacting the dye. Moreover, if the fabric is not placed flat in the machine or is entangled and knotted, it is difficult for the dye to be evenly distributed in these disordered parts of the fabric, resulting in color difference.
3. Quality and addition method of dyes and auxiliaries
The solubility and diffusion properties of dyes and auxiliaries of different brands and batches are different. If the dye is not fully dissolved, there are particles, or the auxiliaries cannot effectively help the dye to disperse evenly, then color spots are likely to appear during the dyeing process. At the same time, if the order and time of adding dyes and auxiliaries are unreasonable, it is not conducive to the uniform mixing of the dye liquor, affecting the dyeing uniformity.
4. Dyeing process parameters
Dyeing process parameters such as temperature, time and bath ratio should not be ignored. Uneven temperature control and different dye liquor temperatures at different positions in the machine will lead to different dyeing rates. If the dyeing time is too short, the dye cannot be fully penetrated and fixed; if the bath ratio is not appropriate, the dye liquor concentration may be too high or too low in local areas, which will have an adverse effect on dyeing uniformity.
