Definitions

  • the present invention relates to device for spinning viscose and, more particularly, the present invention is concerned with producing fibers, filaments, threads and yarns of regenerated cellulose.
  • the degree of substitution of the cellulose after stretching is considerably higher than if the spinning is carried out in the absence of formaldehyde. If one does not cause substantial splitting oif of the residual xanthate groups while the spinning rope is still under tension, regeneration will take place only after cutting the rope or after spinning the endless filaments in a centrifuge, i.e., in untensioned condition.
  • the decomposition of the residual Xanthate in untensioned condition will cause a reduction in the orientation of the cellulose crystallites, which orientation had been caused previously by the stretching of the fiber, and this reduction of orientation will reduce the strength of the fibers and threads. Furthermore, fibers with an excessive residual substitution during decomposition in tensioned condition tend to form adhesions of the single capillaries into clogged fibers Of relatively high titre.
  • the requirements made on the bath in which the stretching of the spun fibers is carried out are somewhat contradictory and difficult to comply with.
  • the degree of decomposition of the xanthate should be low in order to permit maximum stretching of the rope, on the other hand, after the stretching, the xanthate should be decomposed as completely as possible while the rope is still under tension.
  • the present invention contemplates in a spinning arrangement adapted for spinning regenerated cellulose, in combination, spinning means for spinning a yarn, bath means for immersing the yarn in a hot liquid, guide means for guiding the yarn along a predetermined path from the spinning means to the bath means and through the latter, and steaming means along the path between the spinning means and the bath means for steaming the yarn during its passage therethrough.
  • the present invention permits in a simple and effective manner to obtain maximum stretching of the rope combined with decomposition of the xanthates while the rope is still under tension.
  • the coagulated threads may be stretched in steam preferably having a temperature between about 95 and C., and in water preferably having a temperature of between 70 and 95 C. Stretching preferably may be by between 300 and 500% of the original length of the thread. Thereby it is preferred to pass the threads from contact with steam directly into contact with the hot water bath.
  • a short steaming device preceding th hot water bath will assure a favorable sequence of stretching and decomposition of the rope.
  • steaming and hot water bath follow each other immediately so that the rope leaving the steam atmosphere is directly introduced into the hot water whereby the zone in which predominantly stretching and the zone in which predominantly decomposition takes place will be determined by the deformability or plasticity of the rope. Due to the fact that the zones of predominantly stretching of the rope and of decomposition of the same change over into each other and partly overlap it is primarily the deformability of the rope which determines the zone in which predominantly stretching is carried out.
  • the method of the present invention gives particularly good results in connection with conventional spinning methods according to which threads of unripened viscose containing between 4 and 7% cellulose, having an alkali factor of between 1.0 and 1.4 and a gamma value greater than 70 are spun into a cold, heavy metal salt-free spinning bath containing per liter between 60 and 90 grams sulfuric acid, between 1.5 and grams formaldehyde, and between 100 and 150 grams sodium sulfate.
  • the rope Prior to introduction into the steam tube, D, the rope contains considerable proportions of formaldehyde and sulfuric acid. The degree of substitution is high.
  • the formaldehyde and acid content will stabilize the methylolated cellulose xanthogenic acid during stretching in steam of for instance 99 C.
  • saturated steam is preferably used, the actual temperature of the steam will depend on barometric pressure and may be as low as about 95 C. However, it is also possible to use somewhat superheated steam up to a temperature of about 110 C. Thus, generally, the steaming with simultaneous stretching of the rope will be carried out at a steam temperature of between about 95 and 110 C.
  • a device for carrying out the process of the present invention preferably includes a steam tube formed of a material which is resistant against acid, formaldehyde and temperatures of up to 110 C., which tube is arranged between the top godet and a hot water bath.
  • the steam tube extends downwardly from the top godet to the hot water bath in vertical direction. If the lower end of the steam tube is immersed in the hot water bath, a hydraulically closed system is obtained and it is assured that the rope will enter the hot water bath directly from the steaming zone.
  • a direction changing means or roller is located in the hot water bath, which roller or the like, or other guide means, is not driven, so that between the first godet of the spinning device and the final withdrawal means the stretching is carried out in a stepless, continuous manner throughout the steaming and hot water zone. It is achieved thereby that more than of the total stretching of the rope will take place in the steam tube which, as pointed out above, preferably is fed with saturated or low pressure steam, and the hot water bath will serve predominantly for decomposing the xanthate groups of the rope.
  • a tube 3 is arranged communicating with steam conduit 4, and the rope is passed through tube 3.
  • the steam tube 3 preferably extends vertically between top godet 2 and hot water bath 5, so that the rope can initially be passed under the force of gravity downwardly through steam tube 3.
  • the rope is guided by non-driven direction changing roller 6 through hot water bath 5, and withdrawn by means of a final conventional withdrawal arrangement 7.
  • the filament is immersed in the bath for a length of 12 centimeters.
  • the thus formed rope of 3,600 individual filaments is withdrawn from the bath by means of a first godet 11, at a speed of 7 meters per minute, and passed over the top godet which rotates at 13 meters per minute.
  • the cable passes through a vertically arranged glass tube fed with low pressure steam of 99 C. and having an inner diameter of 30 mm. and a length of 800 mm.
  • the lower end portion of the glass tube is immersed for a depth of 20 mm. into the hot wated bath 5, the latter containing 3.9 grams per liter sulfuric acid and 1.5 grams per liter formaldehyde.
  • the thus obtained rope was then cut in conventional manner into staple fibers of 40 mm. length and, without being desulfurized, decomposed in water of 79 C. and containing 2 grams of sulfuric acid per liter, and thereafter bleached, further treated in conventional manner and dried.
  • the thus obtained staple fibers were free of clogged fibers.
  • Staple fibers were also produced under similar conditions however passage through the steam tube was eliminated and thus the rope was stretched and decomposed only in hot water bath 5 having the composition and temperature described above. Stretching was carried out by 350%. Again, the staple fibers were free of clogged single capillaries.
  • staple fibers were produced by proceeding as described above, with passage of the rope through the steam tube but eliminating the subsequent hot water bath. Stretching was carried out by 390%;The thus obtained staple fibers did include clogged single capillaries.
  • Table I below gives the results of analytical determinations carried out with ropes which were produced according to the present invention by passing the rope under tension through the steam tube and the hot water bath 5. The analytical results obtained with the rope produced according to the present invention are described under A.
  • the abbreviation cond. is meant to denote that the fiber has been conditioned by being kept prior to testing for 24 hours at 22 C. and 65% relative humidity.
  • the abbreviation Rkm denotes the Telec length, i.e., the length of the fiber of the same type which must be suspended from the fiber to be tested in order to break the latter.
  • An arrangement for spinning regenerated cellulose comprising, in combination, spinning means for spinning viscose, said spinning means including a viscose-precipitating bath, and spinning nozzle means located in said bath for extruding viscose solution into the same so as to form filaments; steaming means operatively associated with said spinning means for contacting the thus formed filaments with steam, said steaming means comprising at least one upright tube having an inlet for said filaments at its upper end and an outlet therefor at its lower end; watering means including an elongated vessel arranged underneath said at least one upright tube for substantially freely moving said filaments therethrough, said vessel being capable of being filled with hot water up to a predetermined level and said at least one upright tube extending downwardly into said vessel with said outlet of said tube being located below said predetermined level and closer to one end of said elongated vessel, so that filaments moving downwardly through said tube and passing through said outlet will be directly introduced into said vessel below said predetermined level; and guide means for moving filaments, in the indicated sequence, from
  • said guide means include non-driven direction changing means located in said vessel for changing the direction of movement of said filaments therein.
