Title:
PAPERMAKING BELT
Document Type and Number:
Japanese Patent JP2003171891
Kind Code:
A
Abstract:

To provide a papermaking belt improved in releasability of wet paper, by destroying a water film formed between the wet paper and the papermaking belt.

In this papermaking belt 1, many convexity- and concavity- forming components 3 comprising at least one kind of compound selected from a water-soluble inorganic salt, a highly water-absorbing resin, and a water-soluble polymer are dispersed in a papermaking side layer 2 composed of an elastomeric resin, such as polyurethane. Thus, an existing state of the water on the papermaking side surface 21 is changed by renewedly forming the convexities and concavities on the papermaking side surface 21 of the papermaking side layer 2, or by modifying characteristics of the papermaking side surface 21 of the papermaking side layer 2, so that the water film between the wet paper and the papermaking belt is destroyed, and further, the releasability of the wet paper is improved. Further, the belt has suitable hardness, because the concavity-forming components are dispersed in the papermaking side layer of the papermaking belt without being formed into hollows, so that durability and workability of the belt are not deteriorated.
