Spunlaced nonwovens for hot-gas filtration.


André Lang of Jacob Holm Industries GmbH (Germany) has been developing scrim-reinforced spunlaced nonwovens as replacements for needled products in hot gas filtration.
He listed the performance advantages of spunlace over needlefelts, including tightly controlled pore size distribution and improved dust-holding

Reduced levels of particles in clean-gas resulted.
