Calendering and Pressing Machines
topic
Calender machines pass fabric through nips between heated rolls of defined hardness combinations at speeds of 20 to 80 metres per minute and pressures of 20 to 80 kiloNewtons per metre to produce smooth, compressed fabric surfaces, with friction calenders producing a silk-like lustre on cotton and blended fabrics by applying different roll surface speeds creating a wiping action that flattens surface fibres to increase light reflection from the aligned fibre surfaces.
Role
Produces the smooth, lustrous fabric surfaces required for premium shirting, linings, and furnishing fabrics by compressing and aligning surface fibres through controlled heat and pressure application that increases optical reflectance and fabric smoothness, with calender roll configuration, temperature, and pressure determining the degree of surface compaction and lustre development achieved on each fabric type.
