Definitions

  • This invention relates to the manufacture of artificial silk by the viscose process, and has for its object to provide an improved machine for simultaneously spinning, washing and drying the viscose thread in a continuous manner; this machine is of the kind in which the viscose thread, on issuing from each of the squirting nozzles, plunges directly, within a containeighaving the shape of a test-tube, and surrounding the nozzle, into a coagulation bath travelling, along a closed circuit, in the same direction as the viscose thread.
  • the test tube containing the coagulation bath is adjustable vertically with respect to the squirting nozzle, so as to allow of regulating the length of travel of the viscose thread in the coagulation bath, which is an important condition in order to obtain a good. coagulation ofthe thread.
  • Said arrangement also allows the workmen to collect easily the filaments issuing from the squirting nozzles at the beginning of the manufacture, or to clean, open or re place easily andreadily a squirting nozzle, if required.
  • Fig. 1 is a vertical cross section of the improved machine constructed according to this invention. a.
  • Fig. 2 is a partial front elevation.
  • Fi 3 and 4 are horizontal sections taken in tfi: lines 3-3 and 4r4. respectively of i 2.
  • Tis a feeding conduit for bringing the viscose solution in the requisite conditions of P e temper ure nd concentration to each oi'the squirting nozzles. Between this conduit and the several squirting nozzles proper, there is interposed a double filtering apparatus for the solution in such a manner as to arrest any impuritiesthat may be present before they reach the squirtlng nozzles which otherwise they would choke, to the detriment of the quality of the resulting product.
  • Each filtering apparatus comprises two groups A and B designed to enable the corresponding squirting nozzle to have a continuous operation, one of the two groups feeding the squirting nozzle whilst the other group is being stopped for replacing the soiled filter which it comprises. 7
  • Each filtering box 3 comprises a cylindrical reservoir, closed at its upper end by a screw-threaded plug 29 and provided at its lower end with a scre-w-threaded ring 30 which keeps the filtering disc in place.
  • a pointed screw 31 which allows, on replacing the filter into operation before the cock 4 is opened (the cock 2 being open), of discharging any air that may have entered the cylindrical reservoir during the changing of the filter.
  • the viscose thread plunges directly into av coagulating bath contained in a glass container 15, having the shape of a test tube of suitable length, and provided at 16 with an overflow, which connects at 17 with aflexiblerubber pipe 22 that is connected in turn to a collector 23.
  • An up-take casing 25, provided with a movable part, 26, constitutes the foot of the apparatus.
  • a pipe 18 serves for feeding the coagulating bath contained in the several containers 15 corresponding to all the nozzles; this pipe 18 is connected (Figs. 2 and 3), by means of nozzles 19, with cocks20, and by means of a bent tube 21 for each nozzle, to a pipe 21 that dips into the corresponding container 15.
  • each pipe 21 can be adjusted in the desired position in the corresponding test-container 15.
  • nozzles 14 Above and behind the nozzles 14 are arranged two cylinders or rollers 39, preferably of aluminium, by which there is driven at a suitable speed an endless fine metallic web 40 preferably'of aluminium, on which are fixed at intervals small hooks 38 for receiving the filaments 37 issuing from the nozzles 14.
  • nozzle 41 is a pipe provided with a cock for supplying the nozzles 42 which are designed to project a suitable liquid upon the endless web 40.
  • the liquid thus projected after it has passed through the endless web 40, is collected in a series of troughs 43 for subsequent regeneration and re-use.
  • a second series of nozzles 44 fed by a pipe 44', serves to project another liquid against the endless web 40. Inside the latter, and near its lower end is a further nozzle 45 which directs a jet in the direction opposite to the foregoing ones on to the endless web 40.
  • a second endless metallic web 48 travels over rollers 47-47 that are rotated at a suitable speed. Between the two stretches of the endless web 48 there is interposed a casing of sheet metal 49, the rear wall 50 of which is perforated so as to allow of thepassage therethrough, in the direction of the arrows (Fig. 1), of hot air that is supplied by apipe 51 and is drawn by a fan connected to the pipe 52. Above this endless web 48 is a disc 55 carrying the spindle of a bobbin with a threadguide. This disc is driven by friction from a roller 56.
  • the liquids, projected on to the endless web 40 by the nozzles 44 and 45, are collected by a sheet metal casing 61 which encloses the endless webs 48 and 40.
  • the liquid constituting the coagulating bath isbrought in the required conditions of temperature, concentration and volume,
  • the coagulating bath in flowing through the coagulating container 15 in the direction of the travel of .the viscose thread, thus makes a closed circuit in the course of which it becomes purified, regenerated and made ready for re-use according to the desired temperature.
  • the container 15 is lowered so as to leave above the upper level of the nozzle 14 only the minimum height necessary for the coagulation of the filament, and allow the hand labour of the workmen, charged with collecting the first thread, to be performed under the best conditions.
  • the glass container 15 is carried (Fig. 2) by two aluminium collars 35, 36, sliding along guide pillars 31 of aluminium of glass supported by collars or sleeves 33 on the conduit 18.
  • the devices provided for supplying and discharging the coagulating liquid are such that this container 15 can be'lowered (into'the position indicated in dotted lines in Fig. 2) without the liquid contained therein overflowing therefrom. It can alsobe kept in a determined position for regulating'the-length of filament submerged according to the velocity of travel of said filament and therefore regulating the length of the sojourn of the jet of viscose which is squirted into this medium.
  • the container 15 is brought into a position satisfying the conditions for the sojourn of the thread in the medium of the coagulating bath.
  • the lengths of the metal webs 40 and 48 are determined according to the requirements ascertained by experiment in relation to the coagulation and the complete washing and drying of the viscose thread.
  • the nozzles 42 may spray the thread, as it travels along with the endless web 40 for a determined length and number, with a liquid suitable for completing the coagulation. This liquid will in part be collected by the trough device 43 for the purpose of subsequent regeneration.
  • the nozzles 44 will likewise suitably wash the coagulated thread under suitable conditions of space and duration.
  • the jet of the inner nozzles 45 will unstick the thread from the metal web 40 and will facilitate the transference from this web 40 on to the endless web 48 upon which it will be dried by the action of a current of hot air supplied through the pipe 51 in the casing Q9.
  • the thread is then wound on the bobbin 55.
  • a machine for spinning, Washing and drying viscose thread in a continuous manner comprising squirting nozzles, means for feeding said squirting nozzles with the viscose solution, a glass container surround ing each of said squirting nozzles and containing the coagulation bath through which pass the filaments of the thread issuing from the squirting nozzle, means for drawing along the viscose thread at a predetermined speed, means for circulating said coagulation bath in the same direction as the -viscose thread, together with means for vertically adjusting the position of each glasscontainer with respect to the corresponding squirting nozzle, for the purpose described.
