Compacting felts

The new compacting felt introduced by Dollfus & Muller during ITMA 2015

The Dollfus & Muller Nomex felts (aramid felts) are used on Textile compactors or calendering machines in Dyeing houses.

 

The Dollfus & Muller Nomex felts (aramid felts) are used on Textile compactors or calendering machines in Dyeing houses.

Knitted fabrics need to be pre-shrunk and stabilized in order to avoid the subsequent shrinkage of the T-shirts or polos in washing machines.

The compacting Nomex felts facilitate this effect (this is why they can be called shrinking felts) and improve the fabric handle. The shrinkage required (between 2 and 10%) is mechanically given on both sides of the fabric by two consecutive endless felts using temperature (usually between 110 & 160°C / 280 & 320°F) and steam pressure.

For heat-setting processes, carried out between 180-200°C (350-400°F), Dollfus & Muller has developed heat resistant endless felts made with Nomex® (aramid) fibres.

In some countries, the compacting felts are as well called Sanfor felts.

The Dollfus & Muller felts with their optimal compacting rate give the highest dimensional stability and excellent fabric handle.

The compacting felts used in the processing section of the knit manufacturers are used on the following machines : Ferraro, Santex, Sperotto, Lafer, Albrecht, Serteks, Heliot, Ruckh, Monforts, Brückner, Hsing Cheng, Jiangyin Jintian, Dilmenler, Weiss, Hung Jyi, Lafer Türk, Mersan, Bianco, Dong Nam, BH Tech, Fong’s, Poong Kwang, Muzzi, Ssang Ho, Monti, I Kuang, Strahm,…
