Abstract: The present invention provides a paper quality improver for papermaking, which is excellent in efficiency of improving bulky value, brightness, opacity and the like of pulp sheet, wherein the improving is desirable at lightening paper and increasing amount of deinked pulp, if small amount of the paper quality improver is added; and provides a pulp sheet whose bulky value, brightness, opacity and the like are improved. Further, the present invention provides a dry efficiency improver and a drying method which are able to improve easily a dry efficiency of a wet paper and water-squeezed product. That is to say, in the present invention, a compound is used as the paper quality improver for papermaking, wherein the compound is led to have not less than 4% of lyotropic degree measured by a specific method and the compound satisfies at least two of any ones selected from (i) standard improved bulky value of not less than 0.02 g/cm3, (ii) standard improved brightness of not less than 0.5 point and (iii) standard improved opacity of not less than 0.5 point. That is to say, also, in the present invention, there is obtained the pulp sheet, whereby a compound being led to have not less than 4% of lyotropic degree measured by a specific method is added internally into pulp slurry before or in papermaking step, wherein the pulp sheet satisfies at least two of any ones selected from (1) improved bulky value of not less than 0.02 g/cm3, (2) improved brightness of not less than 0.5 point and (3) improved opacity of not less than 0.5 point. Further, the present invention is use, as a dry efficiency improver, of a compound being led to have not less than 4% of lyotropic degree measured by a specific method and satisfying at least one selected from (i) standard improved bulky value of not less than 0.02 g/cm3, (ii) standard improved brightness of not less than 0.5 point and (iii) standard improved opacity of not less than 0.5 point.
