Method, substrate and arrangement for a particle collection and a subsequent particle cleaning

A substrate (40) arranged for a particle collection (“P2”;

• “p2”), comprising a piece of flexible sheet material (41) arranged to collect loose and/or loosened particles (“p2”), and a support layer (42) cooperating with and supporting the piece of flexible sheet material, wherein both the piece of flexible sheet material (41) and the support layer (42) are adapted to be gas- or air permeable for a cleansing of loose particles and/or loosened particles (“p2”), using a generated air stream, which, under an overpressure, is allowed to pass through the substrate (40), in a direction through the support layer (42) and the piece of flexible sheet material (41) and/or using a generated air stream which, under an underpressure, is allowed to pass the substrate (40) in a direction through the support layer (42) and the piece of flexible sheet material (41), characterized in that the said piece of flexible sheet material (41) is arranged to form a filter unit (43) which at least is arranged to collected micro- and nano particles, in that the said support layer (42) for the said piece of flexible sheet material (41) is adapted to display through openings (44) for a distributed air passage through the piece of flexible sheet material of air streams, under an underpressure or an overpressure, and in that the said piece of flexible sheet material (41) displays a micro fiber- or nano fiber structure for a collection of the said loose and/or loosened particles (“P2”, “P2”), in an ionizing state and the state for a variable electrostatic field strength.

Arrangement for cleaning of surface parts (2c, 2c′) supporting loose and/or loosened particles, and wherein the said loose and/or loosened particles at least can display a grain size which for most part can fall within the micro field and/or within the nano field, such as formed by a polishing treatment of a raw surface (2a), whereby an air permeable substrate (40), inter alia in the form of a piece of flexible sheet material (41) and a support layer (42), such as adaptable to be movable in relation to the said surface part, whereby a cleansing of particles (“P2”, “p2”) within the piece of flexible sheet material can take place via an underpressure, acting on a first side of the piece of flexible sheet material, for by generated air streams suck up particles collected within the piece of flexible sheet material and/or a cleansing of particles within the piece of flexible sheet material can take place via an overpressure, acting on the opposite side of the piece of flexible sheet material, in order to by generated air streams blow off particles collected within the piece of flexible sheet material, and where the piece of flexible sheet material and its supporting support layer (42) are both associated with different air permeable properties, characterized in that the said piece of flexible sheet material (41) is adapted to form a filter unit (43) arranged at least for the collection of micro- or nano particles, in that the said support layer (42) for the said piece of flexible sheet material (41) is adapted to display through openings (44) for a distribution of air passages through the piece of flexible sheet material of air streams, under an underpressure or an overpressure, and in that the said piece of flexible sheet material (41) displays a micro fiber- or nano fiber structure for a collection of the said loose and/or loosened particles, in an ionized or electrostatic state.
