Abstract: 558,568. Straw-pulp. FELIX, A., and HORNEMANN, E. Aug. 10, 1942, Nos. 11160/42 and 9772/43. [Class 2 (ii)] Straw is converted into half-stuff suitable for use in making paper cardboard, straw-board, or the like, by placing it in a boiler which is capable of rotation, subjecting it to treatment with boiling water with the boiler rotating so as to clean the straw, further boiling with the boiler rotating so as to effect surface softening of the straw, steaming under increased pressure with the boiler at rest so as to prevent possible scalding of the straw, and steaming with the boiler rotating so as to effect the complete disintegration of the straw into half-stuff. The straw may be cut in a chaff-cutter into small lengths prior to being placed in the boiler which contains water at 150-180‹ F. The boiler is closed and rotated and wet steam is admitted to clean the straw. About one quarter of the water is drained off after several minutes in order to remove dust and larger particles of undesired matter. The steam pressure is then increased to 20-25 lb. per sq. in., and the boiler is rotated to soften and saturate the fibres with water. The whole of the water is then drained off. With the boiler at rest, wet steam at 30 lb. per sq. in. is admitted, and after about 20 minutes the steam pressure is raised to 40 lb. per sq. in. and the treatment is continued for 40 minutes to soften the ligneous and hardened parts of the straw. After draining off the condensed water, the steam pressure is raised to about 50 lbs., and the boiler is rotated for about 5 hours, condensed water being removed every hour. The product is then rinsed with water. Preferably, the liquid in the boiler is maintained in neutral condition by adding the requisite amount of alkali at intervals during the treatment. Sufficient soda ash or lime may be added to the water to remove or reduce any temporary or permanent hardness.
