Abstract: Softwood pulp was used to make overlay paper for determining the effects of beating degree and drying condition on water receptivity and wet tensile strength. The result showed that wet tensile strength of overlay paper was not much high when the polyamine epichlorohydrin resin(PAE) alone was added to the pulp.Addition of 1.3% anion material and 1.5% PAE can increase the wet tensile strength of overlay paper obviously. The water receptivity of overlay paper can be increased distinctly by controlling the beating degree and vacuum degree in the sheet former. Optimal beating degree is 32~34°SR and vacuum degree is below 10 kPa.
Key words: overlay paper, water receptivity, wet tensile strength, polyamine epichlorohydrin resin
