Bohdan Dawidowicz Patent owner: Institute of Artificial and Synthetic Fibers, Lódz (Poland) The method of protecting polyvinyl alcohol fibers against plywood formation in the fiber production process. The subject of the invention is a method of protecting polyvinyl alcohol fibers against plywood formation in the process of their production. In the process of producing polyvinyl alcohol fibers by the wet-forming method, the phenomenon of the formation of a certain number of plywood often occurs, which disqualifies the fiber in further textile processing. In this case, plywood is understood to mean assemblies of elementary fibers glued together, which, after the fibrous carding process, pass into the finished fleece, causing its heterogeneity and thus reducing the use value of the fiber. 15 Until now, polyvinyl fibers, after forming in salt baths, are pressed from the excess of the bath and introduced into a drying device, or after forming in salt baths, they are sprinkled with cold water, drained of excess water and introduced into the drying device. The method according to the invention consists in treating the cable with polyvinyl alcohol fibers, after rinsing with water in order to remove salt impurities from the forming baths, a drip which is an aqueous solution of non-ionic surfactants such as derivatives of fatty acids and ethylene oxide, polyoxyethylene glycol. flax, etc. The content of non-ionic surfactants in the bath is 0.1-50% by weight. The fibers obtained in this way are free from plywood after drying, thermal treatment and acetalisation. The method according to the invention is illustrated by an example. Polyvinyl alcohol fibers, composed of a 15% aqueous solution of polyvinyl alcohol polymer, are introduced into a coagulation bath which is an aqueous solution of sodium sulphate with a density of d = 1.30 and a temperature of 45 ° C, and then stretched to 100% by weight. A stretch fabric of the same composition at 60 ° C. After leaving the stretch bath, the fibers are quenched in a bath containing sodium sulphate and zinc sulphate in an amount of 10 g / l bath, the bath density d = 1.16 and the bath temperature 70-80 ° C. Then the fiber cable, after rinsing with water at 15-20 ° C, is passed through a water bath containing a 150 g / l bath of the reaction product of fatty acid with ethylene oxide. Subsequently, the fibers are dried, thermally treated and acetalized by known conventional methods. 520693 PL
