Dollfus & Muller Nomex® felts (aramid felts) are used on textile compactors or calendering machines in dye houses.
Knitted fabrics are pre-shrunk and stabilized using a compactor, or felt compactor. There are two types of Nomex® felt compacting machines:
- Tubular machines for the shrinkage of tubular knitted fabrics
- Open Width machines for the shrinkage of open width knitted fabrics
The compactor is generally equipped with two steam chambers and two felt units. Most are steam-heated but some can be equipped with a thermo-oil heating system in order to finish synthetic fabrics.
The shrinkage required (2 - 10%) is maintained on both sides of the fabric by two consecutive endless felts using temperature (usually between 110 & 160°C / 280 & 320°F) and steam pressure.
A variety of sizes and thicknesses are available depending on the model of the compactor as well as the type of heating. Dollfus & Muller can also supply Teflon® sheets.
For heat-setting processes, carried out between 350-400°F, Dollfus & Muller has developed heat- resistant Nomex® endless felts.
The compacting felts 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, and Strahm.
