Abstract

265,697. Lymn, A. H., and Leyst, C. Nov. 14, 1925. Pulp, preparation of. - Cellulosic material in cake or block form suitable for use in paper manufacture is obtained from bamboo by finely disintegrating the bamboo, boiling the disintegrated material with quick lime until it can be worked up to a pulp, washing the pulp thus obtained, and submitting it to pressure to produce coherence of the material. Preferably the pulp obtained after the boiling operation is ground before it is submitted to pressure. To refine it the cake or block of material may be treated with a solution of caustic soda and finally bleached by means of a liquor containing chloride of lime.
