método para fabricação de manta com suporte poroso e artio poroso com suporte

摘要

Porous supported articles and methods of making are disclosed. Multicomponent polymeric fibers are introduced into a forming chamber and are infilled at least into the interior void spaces of a support web. At least some of the infilled multi-component fibers are self-bonded to each other to form a porous web that is embedded within the support web. The porous embedded web may contain particles that are bonded to the multicomponent fibers of the web. The optional particles in the porous embedded web may be e.g. abrasive, absorbent, etc.
