Decating
Decatising (pressing) is a typical finishing process for woollen fabrics, woollen cloths, and plaids, in which the fabric absorbs moisture with the help of steam and is pressed between a felt endless belt and a heated calender roller.
This causes the pile to lay flat against the fabric. The effect is similar in principle to a steam iron. The effect can be influenced by pressure, temperature and fabric speed.
Factors in pressing
- Pressure
- Temperature
- Moisture content of the fabric
- Fabric speed
Decatising influences the following fabric parameters:
- higher lustre of the fabric
- The fabric is compacted and acquires a different handle (more compact)
- Drape
- Stiffness
- Dimensional stability
- Shrinkage of the fabric
The fabric is then less fluffy, but more elegant (lustre) and smoother, as well as less voluminous.
In manufacturing, a distinction is made between
Finish decatising (typical for the women's outerwear sector)
Press lustre decatising (typical for the men's outerwear sector)
furthermore
Discontinuous processes (kessel decatising)
Continuous processes (bowl press, wrap decatising)
