Clothing
A clothing, in particular a press belt for a machine for producing or processing a fibrous material web, includes a paper side, a backing side, a base fabric and at least one additional structure. The at least one additional structure is formed of or includes a layer of polymer foam which provides the paper side of the clothing. A method for producing a clothing, and a machine for producing a fibrous material web, are also provided.
1. A clothing or a press belt for a machine for producing or processing a fibrous material web, the clothing comprising:
a paper side;
a backing side;
a base fabric; and
at least one further structure formed of or including a layer of polymer foam, said layer of polymer foam providing said paper side of the clothing;
said layer of polymer foam having an anisotropic pore structure;
said layer of polymer foam being configured to be compressed in a thickness direction by more than 30% under a compressive loading of the clothing of 3 MPa as compared with an initial thickness under a compressive loading of 0.1 MPa; and
the clothing having a permeability of between 10 CFM and 250 CFM.
2. The clothing according to claim 1 , wherein the clothing has a permeability of between 25 CFM and 150 CFM.
3. The clothing according to claim 1 , wherein said layer of polymer foam is configured to be compressed in a thickness direction by more than 40% under a compressive loading of the clothing of 3 MPa as compared with an initial thickness under a compressive loading of 0.1 MPa.
4. The clothing according to claim 1 , wherein said layer of polymer foam is configured to be compressed in a thickness direction by more than 50% under a compressive loading of the clothing of 3 MPa as compared with an initial thickness under a compressive loading of 0.1 MPa.
