A belt (10) for a sleeve roll forms a closed loop and has an inner surface (11) and an outer surface (12). The belt has an elastic body (15) with an outer surface (15a) and a reinforcing structure (30). The reinforcing structure has first yarns (31a) arranged to a first direction (D1), and second yarns (32a) arranged to a second direction (D2). The second yarns (32a) are arranged, at least partially, on the elastic body (15), and/or the second yarns (32a) are arranged to a depth of equal to or less than 2 mm, measured from the outer surface (15a) of the elastic body to a bottom (32a-i) of the second yarn (32a) in a depth direction of the belt. The invention further relates to a use of a belt. The invention further relates to an arrangement comprising a belt and a sleeve roll.

The object of the invention is to provide a shoe press belt which has an excellent strength while the variation in strength among its parts being suppressed, and to provide a method for producing such a shoe press belt. Provided is a shoe press belt for use in a papermaking machine comprising at least one resin layer comprising polyurethane resin, wherein the polyurethane resin comprises as a component a polycarbonate diol comprising one or more unit(s) A expressed by the following formula (1) (wherein R.sup.1 is a branched alkylene group having 3 or more and 20 or less of carbon atoms): ##STR00001##

The present invention relates to a method for producing a film comprising nanocellulose, which method comprises: providing a suspension comprising 50-100 weight-% of nanocellulose based on total dry weight; forming a fibrous web of said suspension on a non-porous support; providing a press fabric comprising a web-side first surface and an opposite second surface, wherein said press fabric comprises a woven first fabric layer arranged in the press fabric as a layer providing said web-side first surface such that said press fabric has a woven surface structure at said web-side first surface; applying said web-side surface of said press fabric into direct contact with said web; wet-pressing said web by conducting said web, arranged between said press fabric and said non-porous support, through a pressing equipment, and drying the dewatered web so as to form said film. The invention further relates to a film produced from said method.

A shoe press belt includes a polyurethane in which a reinforcement base member is embedded, the polyurethane being in one piece with the reinforcement base member. The polyurethane constituting at least an outer circumferential surface of the shoe press belt includes, as an urethane prepolymer component, an aliphatic polycarbonatediol component and an aromatic diisocyanate component, and includes, as a curing agent component, an aliphatic diol component having a carbon number of less than or equal to 6 and an aromatic diol component having two hydroxyethoxy groups. A content of the aromatic diol component with respect to the aliphatic diol component and the aromatic diol component is more than or equal to 10 mass % and less than or equal to 50 mass %. Accordingly, there is provided a shoe press belt suppressed in generation and development of a crack.

A former section including a headbox, a felt, a wire, a forming roll having a suction zone and a forming section, and a gap section defined by the section between the headbox and a position where the felt and the wire are brought together at the forming roll. The headbox distributes a pulp slurry into the gap section to be sandwiched by the felt and the wire to form a paper sheet. A bottom side of the paper sheet contacts the felt and a top side of the paper sheet contacts the wire, and the sandwiched felt, paper sheet and wire wrap around the forming roll. A press roll forms a nip with the forming roll through which the paper sheet is carried by the felt and the wire, and the suction zone of the forming roll is arranged in a section around the nip.
