METHOD FOR STITCH-BONDING OR FINISHING A MATERIAL WEB BY MEANS OF HYDRODYNAMIC NEEDLING, AND PRODUCT PRODUCED ACCORDING TO THIS METHOD

摘要

The aim of the invention is to subject a non-woven, which consists, at least in part, of metal fibers, to a stitch-bonding or surface finishing by means of hydrodynamic needling. The respective material web can be produced exclusively from metal fibers but can also be produced from a blend consisting of metal fibers and textile fibers. The hydrodynamic water pressure during needling depends on the desired pore volume after stitch-bonding.
