D 01 f, ^^ Institute of Artificial and Synthetic Fibers *) Lodz, Poland Method of making pre-folding cap for viscose fibers The patent is valid from October 31, 1962. The subject of the invention is the method of preparing pre-bathing bath for goat fibers by adding to the bath Hitherto, in the production of viscose fibers, especially high-tenacity viscose fibers, they are used as modifiers for pre-baths containing the main components of acid , zinc sulphate and sodium sulphate, various types of organic amines or their condensates with polyoxyethylene glycol. These preparations often cause foaming of the pre-melting bath, which significantly impedes the process of fiber formation. The disadvantage of these agents is also the fact that they disperse •) The owner of the patent stated that the inventor is Henryk Lisik, MSc. all kinds of impurities present in the bath and thus make it difficult to remove them by filtration. It has been found that the above-mentioned disadvantages can be avoided if hydroxylamines are added to the pre-bath in the form of salts with mineral or organic acids in the amount of 1 to 20 g per liter of bath. It turned out that the presence of hydroskylamine in the digestion bath modifies the formation of the fiber and improves the mechanical properties of the fiber by 10 - 20% in relation to the fiber obtained from the bath without this medium. in an infinite bath, hydrcyxylaminfe shows a slight decrease in swelling, and its cross-section has the shape of a bean with smooth edges. An additional advantage of the process according to the invention is that hudroixylamine. it does not lower the surface tension, thanks to which there is no bath foam and it does not disperse pollutants
