PLPublished on December 14, 1960 * um ± M piBOOTE / j Urzedu Palenlowego | OF THE POLISH PEOPLE'S REPUBLIC PATENT DESCRIPTION No. 43587 KI. 29 b, 3/20 Lódzkie Zaklady Wlókienrody *) Lódz, Poland Method of producing crimped viscose fibers Additional patent to patent No. 41121 Patent valid since July 14, 1959 Patent No. 41121 concerns a method of producing crimped viscose fibers in one coagulation bath, containing sulfuric acid (60-95 g / l), sodium sulphate and zinc sulphate, at a temperature of 40-65 ° C. The fibers extend from 20-60% of the flowing bath and repeatedly rinsed upwards water under pressure and finally cuts on a disc cutter. The cut fibers fall into hot water, where they are curled. It has been found that a fiber with a greater degree of crimping can be obtained by creating differences in the thickness of the skin, and thus increasing the asymmetry in the cross-section of the monofilament if the direction is changed. ) The owner of the patent stated that the authors of the invention are Miroslaw Kopa, MA, Waclaw Sopiela, MA, Emil Kraul, and Zbigniew Rybicki. the flow of the coagulation bath in relation to the path of the fiber belt. The most favorable results are obtained when the direction of the bath flow is perpendicular to the path of the fiber. The advantage of the method according to the invention is the possibility of increasing the concentration of sulfuric acid in the coagulation bath in the range of 95-115 g / l, which has a positive effect on the improvement of the properties of crimped fiber.
