Paper support, of impregnation of a resin made from wood pasta produced by the process of manufacture of alkali metal pasta

摘要

Improved resin saturation paper is produced by a mechanical treatment of various types of pulps, which treatment entails twisting, folding, bending and/or breaking of the fibres present in the saturation feed. The improved resin saturation paper has a low mass, shorter resin penetration times and more resin absorption at a given Williams slowness for all normal components of the saturation feed and also for typical mixtures of the components.
