PAPER BASES WITH INCREASED SIZING OF SURFACE AND LOW LINEN SIZING WITH HIGH DIMENSIONAL STABILITY Russian patent published in 2012 - IPC D21H11/00 D21H21/16 D21H21/54 D21H17/67 D21H17/28 D21H19/54 D21H23/00

Abstract RU 2449070 C1

FIELD: textiles, paper.

SUBSTANCE: paper base is intended for internal and external sizing, which has high dimensional stability, and can be used in pulp and paper industry. Paper base contains cellulose fibers, at least one filler, and sizing agent. At that the paper base has a coefficient of hygroextension from 0.6 to 1.5%. The Scott internal constraint in the transverse direction is not greater than 300 J/m², and/or Scott internal constraint in the longitudinal direction is not greater than 300 J/m². Also a method of manufacturing the paper base and versions of paper base are proposed.

EFFECT: increased dimensional stability and durability of the surface of the paper base.
