NICHT-GEWOBENE STOFFBAHN, DIE MINDESTENS EINE SCHICHT DES SPUN-BONDED-TYPS ENTHAELT.

摘要

Non-woven material comprising a web of spunbonded polymeric filaments wherein the web is impregnated with a thermal stabilising agent e.g. a fluorocarbon, before being hot calendered on at least one side. This results in material having an outer surface which is much more resistant to abrasion than an untreated spunbonded surface. The non-woven material may comprise a laminate of layers e.g. two.layers of spunbonded filaments sandwiching a central layer of melt-blown fibres, the laminate being impregnated with a thermal stabilising agent before hot calendering on at least one side.
