Abstract

188,828. Steinhilber, H. Sept. 2, 1921. Addition to 179,885. Drawings to Specification. Pulp, preparation of.-The process according to the parent Specification is applied to the manufacture of cellulose from reeds and similar plants such as cyperacaes, graminaes, and typhacaes, and also to the treatment of the more resistant marrow cells or portions remaining after the crude fibres have been separated, and consists in subjecting the product, during or subsequent to bleaching, to the mechanical treatment consisting of a continuous rubbing and pressing action. In the treatment of the marrow cells, the material is first bleached and the cellulose fibres then separated by continuously rubbing and pressing in the presence of water.
