TH15801A - "How to make paper from banana fibers" - Google Patents

Abstract

A method of finely grinding wheat straw into fibers. By cutting the straw to a length between about two inches and about four inches, wet the straw. Make straw soft by forcing it into pressurized steam. and finely grind the soft straw in a fine grinder that exerts mechanical pressure. To produce fibers that can be used to produce cellulose fiber paper sheets. Straw fibers, together with other fibers in some proportion, such as wood fibers, are used in the wet process, wet-dry process, as is known, to produce soft paper sheets. Medium-density fiber board and rigid board
