A press cover includes at least one polymer layer. The polymer layer contains or has been produced from a polyurethane. The polyurethane has been formed from a prepolymer and a crosslinker, and the prepolymer is a reaction product of phenylene 1,4-diisocyanate and at least one polyol containing caprolactone and carbonate, such as polycaprolactone polycarbonate polyol. A press roll, a shoe press and a method of using a press cover are also provided.

The present invention provides tissue webs and products having improved z-directional properties. The improved z-directional properties may be achieved by providing the structure with a unique three-dimensional surface topography, which increases the structure's Exponential Compression Modulus (K) and Caliper Under Load (C.sub.0). By improving both K and C.sub.0, the present inventors have also been able to provide tissue structures with relatively high Compression Energy (E), which enables the structures to be calendered at high loads without significant loss of sheet bulk or degradation of strength.

A structure for use in industrial fabrics such as paper machine clothing and engineered fabrics is disclosed. The structure includes axially and radially elastic hollow members, and relatively inelastic yarns in various patterns. The structure has a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.

The present invention provides tissue webs and products having improved z-directional properties. The improved z-directional properties may be achieved by providing the structure with a unique three-dimensional surface topography, which increases the structure's Exponential Compression Modulus (K) and Caliper Under Load (C0). By improving both K and C0, the present inventors have also been able to provide tissue structures with relatively high Compression Energy (E), which enables the structures to be calendered at high loads without significant loss of sheet bulk or degradation of strength.

The sheet manufacturing apparatus includes a fibrillating unit that fibrillates a raw material including fibers in a gas, an additive supply unit that supplies an additive, a mixing unit including a first rotating unit that mixes a fibrillated matter fibrillated by the fibrillating unit and the additive supplied by the additive supply unit, a depositing unit that deposits a mixture mixed by the mixing unit, a web forming unit including a mesh belt that transports a deposited material deposited by the depositing unit and a suction mechanism that sucks the deposited material to the mesh belt, and a control unit that changes granularity of a surface of the sheet by controlling at least one of a supply amount per unit time from the additive supply unit, a rotation velocity of the first rotating unit of the mixing unit, and a suction force of the suction mechanism.

A clothing for paper or pulp dewatering machines comprising monofilaments comprising a partially aromatic polyamide. A machine-side fabric layer is provided, and at least the machine-side fabric layer comprises monofilaments with a partially aromatic polyamide. The clothing comprises or is formed by longitudinal threads extending in a running direction and transverse threads extending transversely to the longitudinal threads, and at least some of the transverse filaments are monofilaments with a partially aromatic polyamide.

A structured tissue belt assembly including a supporting layer, a non-woven web contacting layer, and one or more laser welds that attach the bottom surface of the web contacting layer to the top surface of the supporting layer. The structured tissue belt assembly allows for air flow in x, y and z directions. In exemplary embodiments, the structured tissue belt assembly has an embedment distance between the supporting layer and the web contacting layer of 0.05 mm to 0.60 mm and a peel force between the web contacting layer and the supporting layer of at least 650 gf/inch.
