FILTER ELEMENT BASED ON MOULDED NON-WOVEN FABRIC CONTAINING PARTICLES

摘要

FIELD: textiles, paper.SUBSTANCE: filter element comprises porous non-woven fabric. The fabric keeps its shape and has sufficient rigidity to maintain non-planar configuration. The fabric contains thermoplastic elastomeric polymeric fibers and active particles located in the fibers.EFFECT: fabric has a three-dimensional deformation which is characterised by a uniform density along the direction of thickness of the fabric.14 cl, 10 dwg
