Title:

PRODUCTION OF PAPER HAVING SINGLE-SIDED LUSTER

Document Type and Number:

Japanese Patent JPH1025690

Kind Code:

A

Abstract:

To provide a method for producing single side-lustered paper having extraordinarily reduced fine irregularities on the paper surface.

Pulp fibers as a main raw material are machined into paper by a paper machine equipped with a mirror finished Yankee dryer and wet paper is dried by contacting to the Yankee dryer after pressing wet paper in a press part of a pressing process. In this case, the pulp fibers contain 50-100wt.% of enzyme treated pulp fibers based on the total pulp fibers. The enzyme treated pulp fibers have a pulp viscosity reduced in the range of 5-30% based on the pulp viscosity before an enzyme treatment specified in J. TAPPI 44-84 by treating the pulp fibers with an enzyme having activities for decomposing cellulose. The water content of the wet paper containing enzyme-treated pulp at the outlet of the pressing process is brought to be in the range of 53-65wt.%.
