Common dyeing methods of chemical fiber

There are many technological processes in printing and dyeing, so which dyeing machine methods are commonly used in dyeing chemical fiber?

1. Normal temperature roll dyeing: generally, the temperature is below 100 ℃, which is mainly used for dyeing semi gloss nylon taffeta, nylon oxford, nylon twill, etc. This method is easy to produce head and tail color difference, left middle right color difference, crease and other abnormalities.

2. High temperature roll dyeing: the temperature is generally about 130 ℃, which is mainly used to dye polyester taffeta, n66, nylon matting cloth, polyester oxford (filament), etc. this method is easy to produce head and tail color difference, left middle right color difference, crease, color spot and other abnormalities.

3. Overflow dyeing: the temperature is about 100 ℃ to 130 ℃. It is mainly used to dye polyester, such as Chunya spinning, peach skin velvet, polyester oxford, Taslon, nylon polyester weaving, etc. polyester spinning can also be used for overflow dyeing. At the same time, this method is also used for nylon spinning and other wrinkle dyeing requirements. This method is easy to produce color flower, chicken claw mark, straight strip dyeing and folding and other abnormalities.

4. Warp dyeing: it is suitable for all kinds of cloth, but it should be used reasonably according to the quality requirements. The dyeing temperature can be controlled above 100 ℃ to 130 ℃. This method is easy to produce abnormalities such as shallow edge and layer difference.
