Sanfor felts

Sanforizing felts for Sanfor machines

Sanforizing feltThe 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.

These sanforizing felts are used on the following machines : Monforts, Morrison, Brückner, Cibitex, Muzzi, Tepa, Sperotto, Dhall, Yamuna, Ronson, Swastik, Poong Kwang, Bisio, Daroitex, Paganini, Texima, Kyoto …
