A method of producing a filter material is disclosed, the method including (i) applying droplets of a bonding agent over at least a portion of a layer of an open fiber matrix (10) to form adhesive contacting regions bound to individual ones of at least some of the fibers of said matrix layer; (ii) applying an adsorbate filter media to at least a part of said portion such that at least some of said adsorbate media is substantially fixed in place in said matrix layer by said adhesive contacting regions, thereby fixing in place adsorbate media whilst maintaining a substantially open fiber structure of said matrix layer. A filter material is also disclosed, comprising an open fiber matrix layer (10) which incorporates an adsorbate filter media and is joined on an upstream side with a support layer, characterized in that said adsorbate filter media is held in place in said matrix layer (10) by droplets of an applied bonding agent which are bound to individual ones of the fibers of said matrix layer in such a manner that said bonding agent does not substantially affect the open fiber structure of said matrix layer.

L'invention concerne un procédé de fabrication d'un matériau filtrant. Ce procédé consiste (i) à appliquer des gouttelettes d'un agent de liaison sur au moins une portion d'une couche d'une matrice de fibres ouvertes (10), de manière à former des régions de contact adhésives liées à des fibres individuelles d'au moins une partie des fibres de ladite couche de la matrice; (ii) à appliquer des milieux filtrants d'adsorbé sur au moins une partie de ladite portion, de manière qu'au moins une partie desdits milieux d'adsorbé soit sensiblement fixée en place dans ladite couche de la matrice par les régions de contact adhésives, fixant ainsi en place des milieux d'adsorbé, tout en conservant une structure de fibres ouvertes de la couche de la matrice. L'invention concerne également un matériau filtrant comprenant une couche de matrice de fibres ouvertes (10) renfermant des milieux filtrants d'adsorbé et étant reliée au niveau d'un côté amont avec une couche de support, ce matériau étant caractérisé en ce que les milieux filtrants d'adsorbé sont maintenus en place dans la couche de la matrice (10) par des gouttelettes d'un agent de liaison appliqué, ces gouttelettes étant liées à des fibres individuelles des fibres de la couche de la matrice d'une manière telle que l'agent de liaison n'endommage pas la structure de fibres ouvertes de la couche de la matrice.
