Abstract: The invention relates to a shoe press belt comprising polyurethane polymer prepared of a urethane prepolymer containing isocyanate groups and a chain extender, the urethane prepolymer being prepared using 1,4-phenylene-diisocyanate (PPDI) and the chain extender comprising methyl-bis(3-chloro-2,6-diethylaniline) (MCDEA).

Abstract: A disc filter includes several triangular sectors that are connected from their neck section to the body of the disc filter. The sectors form a relatively thin disc that is rotated during filtration in a basin that contains a suspension to be filtered. The side surfaces of the sector have openings through which liquid in the suspension passes into several essentially radial flow channels inside the sector to flow on to the neck section and away from the sector. A separating wall is formed between two adjacent radial flow channels. Furthermore, the sector is made of two side elements, which are of plastic material and the mating surfaces of which are placed against each other.

Abstract: A method for manufacturing a press felt with a seam, to a press felt, and a base fabric of a press felt. The base fabric is a one-base structure with machine direction yarns forming seam loops and further machine direction yarns running in the web-side surface layer. The machine direction yarns weave with cross yarns. The yarn ratio of the surface layer machine direction yarns to the intermediate layer and further the bottom layer machine direction yarns is at least 2:1:1. In addition, the surface layer machine direction yarns have a long run and their cross-sectional area is smaller than the yarns forming the seam loops.
