Abstract

<PICT:0451860/IV/1> Continuous filaments of cellulose xanthate are collected from a large number of spinning nozzles to form a bundle which is cut into staple fibres, and the cut fibres are opened up by a strong current of liquid which converts the cellulose xanthate into cellulose, and then forwarded in a continuous process to subsequent treatment baths. The bundle of fibres may also be subjected to the loosening action of the flowing, washing and after-treatment liquids. For the initial precipitation of cellulose xanthate threads soluble in water or alkali, solutions of ammonium sulphate, organic acids, or dilute mineral acids may be used. Dilute mineral acid such as sulphuric acid may be used for converting the cellulose xanthate threads into cellulose threads. The conversion bath may contain sodium sulphate or an oxidizing agent such as hypochlorous acid, hydrogen peroxide, or a substance obtained by causing a hypochlorite to react with p-toluene sulphonamide. The artificial fibres obtained are strongly and permanently crimped and may be used as a substitute for wool. As shown, cellulose xanthate threads, obtained by extruding viscose into a solution of ammonium sulphate containing a little sodium sulphate, are passed as a thick bundle a to a cutting device c. The cut fibres fall into trough d and are carried down tower e provided with baffles f by a stream of conversion liquid such as dilute sulphuric acid and sodium sulphate. The fibres are received on a conveyer sieve g and transported to a further trough d and tower e where they are treated with further conversion liquid or with washing liquid. The fibres are then passed to and through similar apparatus where they are treated with washing and other liquids, and they are then passed through a drying device i. Rollers h are provided for squeezing liquid from the fibres. The liquids after use are collected, adjusted to the original concentrations, and returned to the towers by means of pumps m. The fibres are loosened during passage through the towers. If desired, the towers may be omitted and the various liquids may be vigorously sprinkled on the fibres on the conveyer sieves. This sprinkling may be supplemental to the treatment in the towers.
