Filter Paper Studies VI - Effect of Viscose and Asbestos Types

Abstract

Progress made in the development of a domestic substitute for esparto fiber in the Navy type H-60 filter paper is outlined. Two mill runs and the associated laboratory research work are described on mill procedures for the manufacture of cauterized viscose-asbestos filter papers. It is shown that bright viscose rayon may be used in place of the dull grade and that Blue African asbestos may be used in place of Blue Bolivian. The shrinkage problem on the machine driers is appreciable decreased by the use of bright viscose. The most efficient Navy filter paper made on a semiproduction scale is discussed. Operation of the Hydrapulper, used in the production of viscose-type filter material, was satisfactory.
