Abstract

214,882. Wuensch, E., and K÷ppel, P. July 9, 1923. Pulp, preparation of. - In extracting fibres suitable for spinning, and for paper making, from flax, hemp, straw, peat, and the like, the materials are treated with insoluble or difficultly soluble substances in the presence of a liquid. By this treatment, the incrustations become brittle and friable, and the fibres mav be freed therefrom by washing or by combing. In examples mentioned, for treating flax and rye, finely powdered calcined magnesite, finely divided kieselguhr, and kaolin are mentioned, and it is stated that, generally, the difficultly soluble, or totally insoluble oxides or hydroxides of the alkaline earth metals or of the earth metals may be employed, also woodtar, blood charcoal, absorbent or similar charcoal, bole, clay, loam, finely precipitated insoluble or difficultly soluble salts such as barium sulphate, sulphate and carbonate of lime, phosphates, and the like. The substances may be used with the known steeping liquids, and the process may be carried out in the cold or by heating, either under atmospheric pressure or under increased pressure.
