How is the adaptability of GQY Air - Liquid Dyeing Machine to dyes?
Jan 17, 2025
1. Reactive dyes
Reactive dyes with dual active groups are more suitable. Using the same type of dyes in the same dye mix, such as salt-controlled and alkali-controlled dyes divided according to the influence of salt and alkali addition on the affinity of grey cloth, is more conducive to level dyeing and shortening dyeing time, and can avoid step differences and yin-yang color differences caused by asynchronous dyeing and fixation.
2. Direct dyes
Some direct dyes can be used in this dyeing machine. Direct dyes are simple to dye, with a complete color spectrum and low cost. They are suitable for cotton, linen, silk, wool and other fibers, and can meet the needs of GQY Air - Liquid Dyeing Machine for dyeing a variety of fabrics. However, it should be noted that their washing and light fastness are poor, and they can be improved through appropriate post-treatment.
3. Sulfur dyes
Most sulfur dyes are insoluble in water and organic solvents, but can be dissolved in sulfide alkali solution. They can be directly dyed with fibers, and have a complete color spectrum, low price, and good color fastness. They are suitable for GQY Air - Liquid Dyeing Machine to dye some conventional fabrics, but because the dye solution is highly alkaline, it is not suitable for dyeing protein fibers, and the color is not bright enough.
4. Disperse dyes
Due to its low solubility in water, it is a dispersion and belongs to non-ionic dyes. It is mainly used for polyester dyeing and has high color fastness. GQY Air - Liquid Dyeing Machine is well suited for disperse dyes when dyeing polyester fabrics.
5. Coatings
Coatings are mechanically attached to fibers through resins and are suitable for all fibers. When GQY Air - Liquid Dyeing Machine uses coatings for dyeing, dark fabrics may become hard, but the color registration is accurate, and most of them have good light fastness and washing fastness, especially suitable for medium and light color dyeing.
