Dyeing machinery and processes
The dyeing process can be carried out in different modes:
- Continuous
- Semi-continuous
- Discontinuous (batch)
The choice of dyeing equipment depends on the type of fabric (woven, nonwoven and knitted), fibre (natural or synthetic) and the chosen class of dye.
Continuous dyeing
- Feeding the textile substrates continuously into a relatively small pad bath containing the dyestuff and auxiliaries.
- Aiming high production.
- Consists of dye application, dye fixation with heat or chemicals and finally washing.
- Most suitable for woven fabrics.
- The machine's length controls the speed.
