Definitions

  • ABSTRACT A machine for the continuous spinning and treatment of viscose rayon filaments and yarns, comprises means for extruding the filaments, a coagulating bath, filament stretching means and filament progressing means for continuously treating, washing and drying the filaments to obtain a completely treated yarn, as well as means for physically separating the treatment space from the exterior environment.
  • This invention relates to an improved machine for continuously carry-out, under conditions of high productivity and yield, and of regularity of operation and production, the entire processing cycle leading to the formation of viscose rayon filaments and yarns, starting from the spinning of spinnable viscose dope into a coagulating bath, and yielding a product which is spun and, if desired, twisted, wound-up and packaged so that it may be sent as such to the production of textile goods.
  • viscose rayon fibres and yarns comprises a sequence of operations and treatments.
  • the spinnable viscose dope when it is suitably extruded through spinning nozzles into a coagulating bath, is transformed into filaments which, after having been stretched, require a sequence of other physical-chemical treatments which typically include desulphurizing, bleaching and other processes, in suitable liquid processing baths, separated by washing treatments, and at the end undergo a final drying treatment whereafter they are wound-up, optionally as a twisted yarn resulting from the coupling of a plurality of filaments, and preferably after the application of sizing and/or lubricating agents.
  • This technology of spinning and treating viscose rayon fibres is well known and does not require further comments.
  • the improved machine according to the invention generally embodies such advantageous technical solutions, but they are integrated and completed so as to ensure a higher production together with a more favorable and selective treatment, all this in such a way as to achieve an increased yield of the machine or installation, both from the quantitative and from the qualitative viewpoints.
  • FIG. 1 represents, essentially in elevation view and partially in cross-section in a vertical plane parallel to the axis of the main roller, a complete improved machine according to the invention, wherein there have been omitted and simplified numerous purely structural and constructive details of components which individually are not characteristic of the said invention.
  • FIG. 2 represents, schematically and in cross-section and perspective view, approximately on the plane and in the direction indicated by IIII in Fig. 1, the characteristic arrangement of the main and auxiliary rollers.
  • FIG. 3 represents, partially in elevation view and partially in cross-section and likewise with constructive simplifications, the part of the improved machine which is circumscribed by the contour indicated by III in FIG. 1.
  • FIG. 4 fragmentarily represents the structural coupling of two machines of the type represented in FIG. 1 and which comprise systems for carry-out the final yarn drying phase, after the spiral-like paths of the yarns about the rollers.
  • FIG. 5 represents, also schematically, the application of complementary means which cooperate to the removal from the individual yarns of the liquid agents fed thereto in the course of any one of the treatments, in order to improve the predisposition thereof to the successive treatment and concurrently to improve certain working and operating conditions of the machine.
  • FIG. 6 represents in cross-section and in detail a possible embodiment of the complementary means.
  • a machine for the continuous production treatment of rayon viscose filament and yarns comprises a viscose spinning and coaging a number of orifices equal to that of the filaments which can be processed concurrently in the machine, immersed in a coagulating bath 12, and operating at the inlet of a known coagulating and stretching tube 14.
  • the spinner-ct 10 which may be fed for example through a piping 16, is obviously associated to known volumetric pump devices, and likewise the coagulating bath 12 is associated to means which ensure that the same is maintained at the desired levels, in its various parts, that the bath liquid is circulated and regenerated, and so on.
  • the treatment and washing liquors are fed onto the corresponding zones 18a by spraying or by pouring them, preferably by means of jets which impinge on the filaments, in such a way that the liquor will come into contact with the entire surface of the individual filaments.
  • a tank 22 Under the main roller or drum 18 there is positioned a tank 22, which in turn is divided by suitable partitions 24 into as many zones 22a wherein the treatment liquors operating in the overlying zones 18a are selectively gathered, the liquors thus gathered being evacuated through suitable conduits 26 in order to be removed and if desired recovered and regenerated.
  • FIG. 2 there is schematically shown the trajectory along one spiral coil of as many filaments 30a-30d the individual coils whereof all circumscribe the main roller and selectively circumscribe each one of the auxiliary rollers 28a-28d, in this order.
  • the several filaments travel each along numerous spiral coils before they are transferred, preferably through the intervention of thread guides or thread shifting pulleys, into the successively adjacent zone.
  • the zones are represented in FIGS. 1 and 3 as if they had equal axial dimensions. It is obvious that they could have different dimensions, in agreement with the different times required to ensure the completion of individual treatments, and that is of the number of spiral coils along which the filaments must travel in the corresponding zones.
  • the yarns thus obtained are ready to be led to their packaging, for example in bobbins or cops 32, wound about known ring spindles or in bobbins actuated by winding machines with controlled speed and tension.
  • the whole of the essential components is combined and supported in a structurally unitary assembly, having a rigid structure fragmentarily indicated by 34 and mounted on suitable foundations 36 which comprise shoulders 38 and 40 for supporting the rollers and the relative actuating means (not shown), and so forth.
  • the entire assemblage is enclosed in a work chamber which is easily accessible for example by opening broad lateral ports 42 and 44 which are slidable and amply provided with transparent panels permitting the observation and the control of the machine in operation.
  • the closed chamber 46 wherein the machine operates is provided with suitable suction means 48 associated with hoods 50 or other means for evacuating the vapors and the matters which evolve in the course of the various treatments.
  • FIG. 4 shows by way of example a possible way of grouping several machines, for instance by coupling two machines M1 and M2 set side by side, which machines individually produce yams that are suitably wound for example about ring spindles or others as exemplified at 32' and 32". Grouping several machines permits for example to unitize or combine various servicing means, such as those of the preparation and feed of the spinnable dopes, the regenerating circuits of the treatment and washing baths and so on.
  • FIG. 4 exemplifies further a preferred technical solution for the completion of the treatments.
  • These treatments must necessarily end with a phase of complete drying of the treated yarn. This drying may be effected for instance by repeatedly passing the yarn, under the conditions described with reference to FIG. 2, about a terminal zone of the main treatment roller, a zone which is suitably heated.
  • the yarn may undergo and generally does undergo spontaneous length variations which may be of a suubstantial amount, generally a significant contraction. Therefore, the drying treatment, if carried-out while the yarn travels in a spiral path round a main and auxiliary rollers, the geometrical parameters of which are obviously con stant, may cause harmful phenomena, and particularly may cause stresses in the direction of the length of the yarn (and which may even produce a flattening of the same) because the actual presence of the rollers prevents the yarns from freely or even controllably (such as under a predetermined countertension) changing their length.
  • yarns and 30 are removed from the treatment and auxiliary rollers at least before their drying has been completed and are passed under conditions of free or controlled tension through elongated drying chambers 52 and 52", wherein suitable heating means are disposed, which means may be for instance generators of infrared radiations, generators of high frequency fields, or simple radiators consisting for instance of electric resistors, and associated with suitable reflecting means for concentrating the radiating energy onto the advancing filaments.
  • suitable heating means may be for instance generators of infrared radiations, generators of high frequency fields, or simple radiators consisting for instance of electric resistors, and associated with suitable reflecting means for concentrating the radiating energy onto the advancing filaments.
  • Within the drying chambers there may also flow, preferably countercurrent with respect to the direction of travel of the yarns, suitably dried gaseous streams, so as to associate the drying to a removal of the liquid evolving from the filaments.
  • the yarns are led to the winding, if desired after passing in contact with rollers or other means 54to and 54
  • one essential condition for an high productivity of a machine of the type indicated consists in the speed of travel of the filaments, which speed depends on the spinning, coagulating and stretching conditions and is defined by the peripheral speeds of the treatment and auxiliary rollers. It is obvious that such speed should be as high as possible, compatible with the spinning and collection of the yarns.
  • the various treatments and intermediate washing phases strictly demand that the yarns remain in contact with the treatment agents and washing liquors for predetermined lengths of time. This requirement becomes translated into a number and length of spiral coils, that is into the length of the path along which the yarns travel within each zone of the treatment drum.
  • the high production speed causes a corresponding increase of the axial and diametral dimensions of the treatment roller.
  • these dimensions may be advantageously contained within desirably low limits (consequently reducing the overall outer dimensions, the weight and the cost of the complete machine) by shortening to the highest degree the times required for the total elimination of the liquids fed onto the yarns in the course of each treatment phase, before they are transferred to another zone of the treatment drum to undergo a treatment with different chemical agents.
  • the yarns undergo a first energetic action of mechanical removal of the liquids which are present thereon at the exit from each treatment or washing zone, so that the washing liquids transported by the yarns do not cause a progressive dilution of the treatment liquids.
  • Such action may be effected as shown by way of ex ample in FIG. 5, by projecting energetic gaseous jets,
  • FIG. 6 shows by way of example a device by means of which at least partial elimination of the liquid substances carried along by the yarns may be effected in a particularly energetic manner.
  • This device comprises an elongated body 60, axially perforated so as to be longitudinally traversed by the yarn, comprising an inlet chamber 62, a series of stepwise divergent passages 64 and an outlet chamber 66, the inlet and outlet chambers being respectively connected to conduits 68 and 70 through which gaseous streams previously dried and preferably heated are fed and respectively drawnoff, the streams flowing at high speed, possibly at supersonic speed, through the intermediate passages 64, thereby energetically acting phisically to withdraw the liquids carried along by the yarns, which liquids are at least in part evacuated through conduit 70.
  • auxiliary means, devices or mechanisms may be associated to the improved machine, further to increase its qualitative and quantitative efficiency and generally to increase its productivity and the safety of servicing and maintaining it.
  • a machine for the continuous spinning and treatment of viscose rayon filaments and yarns of the type including, in a structurally and operatively unitary assembly, a unitary supporting structure, coagulating bath means, spinning means for extruding filaments into the coagulating bath means, stretching means operable to stretch the coagulated filaments, and progressing means for progressively advancing the stretched filaments along the spiral-like path through a sequence of zones individually designed for sequential treating and washing of the filaments, with the progressing means including a rotary drum and the zones being axially juxtaposed along the rotary drum, and drying means operable to dry the filaments and produce a completely treated yarn; the improvement comprising, in combination, a ventilated casing enclosing said structurally and operatively unitary assembly to physically separate the treatment space therein, wherein gases, vapors and harmful substances are evolved, from the exterior environment in which operating personnel may be stationed during regular operation of said machine; yarn-collecting and winding means operable to collect and wind the treated and dried
  • said liquid removing means comprises nozzles connected to a source of gas under pressure and positioned and oriented to project jets of gas onto the yarn leaving an immediately-preceding zone before the yarn enters the immedi- 7 ately-following zone.
  • liquid removing means comprises respective tubular bodies tra- 8 versed by the yarn between adjacent zones; and means applying said respective tubular bodies with gas under pressure to subject the yarn traversing the tubular bodies to high speed gaseous streams.
