Title:
PRODUCTION OF SIDE-GLAZED PAPER
Document Type and Number:
Japanese Patent JPH05331793
Kind Code:
A
Abstract:

PURPOSE: To provide the method for producing the one side-glazed paper capable of increasing the paper-producing rate and of enhancing the glossiness of the glazed surface to a prescribed level or higher, when the one side-glazed paper is produced with a Yankee drier type paper machine.

CONSTITUTION: Wet paper produced from a cellulose pulp raw material is controlled to water content of 30-45wt.% and subsequently dried with a Yankee drier to produce the one side-glazed paper. The one side-glazed paper is passed through a soft calender comprising a metallic roll and an elastic roll having a Shore D hardness of 80-96 degree for the surface treatment of the paper at least once so that the glazed surface side of the paper contacts the metal roll. The control of the water content of the wet paper is performed by adopting a method comprising setting a pre-drier in front of the Yankee drier or a method comprising strengthening the wire part or press part of the paper machine to enhance the removal of the water content. The one side-glazed paper having a glossiness of ≥27% can be produced at a paper-producing rate of ≥350m/min.
