The Dollfus & Muller sanforizing felts are used on the Palmer unit of the compressive shrinking range or sanforizing machine.
The sanforizing machine does for plain woven fabric what a compactor does for knitted fabrics : Pre-shrinking and stabilization. The difference comes from the fact that the shrinkage is not given by the felt, but by a thick rubber belt using steam and mechanical pressure on the first unit of the machine. Sanforizing machines are used in shirting, bottom-weight and Denim finishing plants.
The sanfor felt also called Palmer felt, shrinking felt, zero zero felt blanket, drying felt or Sanfor blanket has mainly two purposes:
- To dry the wet fabric coming from the shrinking unit,
- To improve the fabric handle.
Dollfus & Muller felts offer the best drying, an excellent shrinkage control and a very good hand to the fabric.
Dollfus & Muller has developed special reinforced Denim Sanfor felts in order to resist longer to the chemicals used in Denim processing.
