Abstract
An apparatus and method for a tactile air filter including a filter media composed primarily of glass fibers having a softening finish applied thereto.
Claims33
A tactile air filter comprising:
- a filter media formed substantially of a plurality of glass fibers and having at least one surface and an interior;
- a cured base resin interspersed over said at least one surface and throughout said interior and bonded thereto in an effective amount to substantially adhere said plurality of glass fibers together;
- a layer of fiber finish interposed between said cured base resin and an atmosphere of ambient air in an effective amount to substantially soften said filter media;
- said layer of fiber finish substantially bonded to said cured base resin and encapsulating said cured base resin and said plurality of glass fibers;
- and
- said layer of fiber finish interspersed over said at least one surface and throughout said interior of said filter media.

A method of forming a tactile air filter, comprising the steps of:
- forming a web of glass fibers into a filter media suitable for filtering a fluid flow;
- atomizing a base resin;
- spraying said atomized base resin from a spray head substantially in a spray direction toward said web of glass fibers;
- dripping a fiber finish drip in a drip direction transverse to said spray direction;
- wherein said fiber finish drip is interposed between said filter media and said spray head during said spraying of said atomized base resin;
- agglomerating said atomized base resin spray and said fiber finish into a separate binary composite;
- depositing said separate binary composite on said web of glass fibers;
- curing said base resin on said filter media at a temperature sufficiently high to melt said fiber finish, thereby melting said fiber finish;
- wherein said cured base resin is sufficiently adhesive to bond to said glass fibers and to bond said glass fibers together at intersections of said glass fibers;
- and
- wherein said melted fiber finish has a sufficiently low surface energy in relation to said base resin that said fiber finish substantially migrates to an outer position proximate to an atmosphere of ambient air, thereby forming an outer fiber finish layer.

A method of forming a tactile air filter, comprising the steps of:
- forming a web of glass fibers into a filter media suitable for filtering a fluid flow;
- atomizing a base resin;
- atomizing a fiber finish;
- spraying said atomized base resin through a first port of a spray head substantially in a spray direction toward said web of glass fibers;
- spraying said atomized fiber finish through a second port of said spray head substantially in said spray direction toward said web of glass fibers;
- agglomerating said atomized base resin spray and said atomized fiber finish spray into a separate binary composite;
- depositing said separate binary composite on said web of glass fibers;
- curing said base resin on said filter media at a temperature sufficiently high to melt said fiber finish, thereby melting said fiber finish;
- wherein said cured base resin is sufficiently adhesive to bond to said glass fibers and to bond said glass fibers together at intersections of said glass fibers;
- and
- wherein said base resin is sufficiently viscous in relation to said melted fiber finish film that said base resin film substantially migrates to an inner position proximate to said glass fibers and said melted fiber finish film is displaced to an outer position relative to said glass fibers, having said cured base resin film interposed therebetween, thereby forming an outer fiber finish layer.
