Abstract

Provided are a method for producing a pulp sheet that is able to sufficiently reduce a moisture content prior to a dryer part, and a dewatering improver for pulp slurry. The method for producing a pulp sheet including passing pulp slurry through a wire part, a press part, and a dryer part to dewater the pulp slurry, wherein the pulp slurry includes an ether type nonionic surfactant. A dewatering improver for pulp slurry including an ether type nonionic surfactant, wherein the ether type nonionic surfactant is a homopolymer of polyoxypropylene or a copolymer having a polyoxyethylene chain and a polyoxypropylene chain in a structural unit, and a content of the polyoxypropylene chain in the copolymer is 85% by mass or more. Figure 1.
