Calender Pressing
Also known as: Calender pressing, hot calender pressing, compaction pressing
Warm pressing process between a heated metal roller and a softer counter roller — smooths, compacts and stabilises fabrics in the final finish without changing the fibre structure.
Description
Calender pressing (also warm calender pressing) is a special form of calendering in which fabrics are guided in the final finish through the interaction of a heated hard-chromed steel roller and a soft counter roller (paper, wool, cotton or elastomer) under defined pressure. Unlike pure calendering, the focus is less on surface compaction than on dimensionally stable fixation and controlled finishing of the fabric surface.
Typical fields of application are laminates with membrane, cotton sweat fabric after sanforising, technical non-wovens as well as coating substrates that need a plane-parallel surface before coating. The process can be finely controlled with different temperatures (up to about 220 °C), pressures (up to about 400 N/mm) and web speeds.
- Compacts and smooths without building up surface gloss
- Important for membrane laminates and coating-ready substrate fabrics
- Heated steel roller + soft counter roller — temperature up to about 220 °C
- Fixes the fibre layer before subsequent coating or bonding
