Abstract: A papermaking belt may suppress resin fallings from the resin layer during its use. Such a papermaking belt may be used in a papermaking machine and may include at least one resin layer including a resin, wherein the total number of swellings whose height is equal to or higher than 50 ?m and cracks whose length is equal to or longer than 10 mm on at least one surface of the resin layer is equal to or less than 1.0/m2. Such a papermaking belt may be used in a papermaking machine and may include at least one resin layer including a resin. The resin layer may be formed using a resin composition including an aqueous dispersion of a urethane resin. The resin composition may include an organic solvent whose boiling point at 1 atm is equal to or higher than 100° C.

Abstract: Provided is a papermaking belt that is used in a papermaking machine and that comprises a first plane on which a wet paper web is placed and a second plane on the opposite side to the first plane, wherein the papermaking belt comprises a reinforcing fibrous substrate layer comprising at least one layer of a woven fabric, at least one layer of said woven fabric comprises a double or more combination weave pattern, said combination weave pattern comprises first yarns and second yarns that are placed in parallel; said first yarns are placed closer to the first plane-side than said second yarns and said second yarns are placed closer to the second plane-side than said first yarns; and said second yarns comprise a polyester yarn.

Abstract: There is provided a shoe press belt for a papermaking machine, comprising one or more resin layers. At least a part of the resin layers comprises a polyurethane resin comprising polymeric MIDI as an ingredient. The polyurethane resin may be a resin obtainable by reacting one or more curing agent(s) having an active hydrogen group, polymeric MDI and one or more urethane prepolymer(s) having a terminal isocyanate group, the urethane prepolymer(s) being obtainable by reacting one or more isocyanate compound(s) with one or more polyol(s).

Abstract: A shoe press belt with excellent mechanical properties, in particular a shoe press belt with excellent crack resistance and excellent resistance to land edge deficiency. The shoe press belt includes a felt-side resin layer containing a resin formed by curing a prepolymer having a terminal isocyanate group (—NCO) with a curing agent, wherein the prepolymer contains, in reacted form, a compound comprising 1,4-bis(isocyanate methyl) cyclohexane and a polycarbonate diol, and wherein the felt-side resin layer has grooves that are configured to receive water squeezed from a felt.
