Definitions

  • the present invention is related to a new spinning system within a fluid medium that transforms the fibres into yarns by utilizing a fluid medium in which the fibres are inserted, moved and transformed into yarn (spinning) by means of the control and variation of determined parameters of the fluid system and the movement control of the fibres to spin, and at the same time they can obtain a physical and chemical treatment in said fluid medium from the recognized in the textile sector, simultaneously with the spinning being carried out.
  • the present invention consists of a system or machine which produces and treats yarn from fibres through the establishment, variation, and control of static and dynamic parameters of the fluid in which the fibres have been introduced, that at the same time causes physical overlaying effects, the drawing out, twisting in the fibres themselves.
  • the system essentially has a set of fluid pipes in which said fluid circulates in a closed system under pressure, in the interior of which exists one or several intakes through which the fibres in the fluid system are introduced, dragged by a fluid; there also exists one or several outlets for the yarn in the fluid circuit.
  • This circuit has some fluid driving mechanism, e.g. pumps, in such a way that one can modify all of the variables that affect the speed, the flow rate, the pressure, etc. and the intakes have the possibility to change the surface of the clearance which can also be done in other points of the circuit, as well as the predetermined modification of the direction of the fluid stream to cause the desired movements of the textile fibres.
  • fluid driving mechanism e.g. pumps
  • fibre introduced in the fluid medium are doubled or overlay when the two intake nozzles of fluid and fibres are connected in parallel, or two pipes converge at a point, and each time a Venturi effect is used (increasing of speed in the medium as a cause of the diminishing of the clearance) a drawing (stretching) of the fibres is carried out. This is necessary in order to synchronize or organize the fibres and place them one respect to another as parallel as possible.
  • auxiliary devices can be arranged that might help to parallelize the fibres in the interior of the fluid.
  • These devices can be for example, ripplings (card clothings), that provide mechanical help within the fluid to parallelize the fibres, fins, deflecting blades, nozzles for the introduction of air under pressure and other fixed or movable elements which permit to modify the direction of the fluid at will.
  • the twisting of the yarn is carried out through the application divers effects which can be combined or not among themselves and can be applied simultaneously or in deferred phases.
  • the distinct effect and degrees of twisting is achieved through the application of conventional techniques very well recognized in the technical standard of fluids dynamics, through whose controlled utilization the fluid path diverges, and consequently that of the circulating fibres.
  • a circular movement of the yarn around itself is generated by causing the creation of a Coriolis effect, or any change of direction is carried out in any of the three spatial directions (e.g. 180 degrees of deviation, multiple changes of spiral direction, etc.) all that for applying a controlled twisting motion to the yarn, the above mentioned can be combined with individual changes of the clearance to internally cause Venturi effects, and with the injection of more fibres in determined points.
  • the twisting of fibres is produced when the fibres interlace among each other, once they have been attached as parallel as possible to one another. As we mentioned before, that can be achieved through the manipulation of solids and/or through the insertion of new fibres through additional nozzles (with ability of Venturi effects or not), in such a way that the fibres remain interlaced and twisted. Once the effect within the system is achieved, the already doubled and/or stretched and/or twisted yarn is collected by a folding system which might be a conventional spindle or another folding system that already exists in the market.
  • the type of fluid medium might be any of the ones used in the industrial practice.
  • the dimensions of the pipe or pipes used for configuring the circuit may be of any kind, and the driving pumps and injection as well as the control elements (pressure gauges, etc.) programming of the operations can form, together with the required injectors, subsystems that achieve the results in laminated or turbulent form in the interior of the pipe.
  • FIG. 1 a scheme showing the causing of the Venturi Effect in a tubular line
  • FIG. 2 a scheme showing the creation of torsion of some Fibers to obtain twisted yarn.
  • FIG. 3 A scheme of a fluid system of the invention with three intake nozzles for fibres and an outlet for yarn.
  • FIG. 4 schematic view of the fluid injection area, with or without fibres
  • the fluid together with the textile fibres it transports is introduced into a pipe assembly through the nozzles I 1 , I 2 , I 3 .
  • the injected fluid in I 1 undergoes a Venturi effect in E 1 , when it enters the circuit C 1 , which causes a stretching of the transported fibres, whereas the fluid with the fibres goes on with it's trajectory until point 1 , wherein the fluid with stretched fibers coming from 11 merges with stream coming from I 2 .
  • the fluid in this circuit C 1 is driven by the pump B 1 .
  • the injected fluid in I 2 undergoes a Venturi effect in E 2 , when it enters in the circuit C 2 , which causes a stretching of the transported fibers, wherein the fluid with the fiber continues with its trajectory until it reaches point 1 wherein it merges with this stream of fluid with stretched fibers coming from I 1 and I 2 causing the folding or doubling of the fibers coming from l1 and l2.
  • the injected fluid in I 3 undergoes a Venturi effect in E 3 when it enters in the circuit C 3 , which causes a stretching of the transported fibers.
  • the fibers continue their run towards point 2 where the fluid with the folded/stretched/pre-twisted fibers coming from I 2 joins the steam which comes out of I 2 joins the stream again causing a folding or doubling of the fibers which also causes a reduction of the pipe's section coming from 2 and I 3 causing due to the Venturi effect, an additional stretching of the fibers coming from I 2 and I 3 ;
  • the fluid stream with said fibers joins the lower horizontal zone of the pipe coming from I 3 in an off-centered way with respect to the axis of said conduction thereby causing a vortex effect of the fluid which in turn causes a pretorsion of the fibers at that point.
  • the fibers transported by the fluid reach point 3 where a rotation of the fluid is caused by the Coriolis which in turn causes a twisting of the fibers, which already have taken the form of a stretched and twisted yarn, which can be extracted from the pipe through the outlet to be later wound up or collected in any other conventional form.
  • the fluid in this circuit 3 is driven by the pump B 3 .
  • the described preferred embodiment has been carried out only as an example.
  • the fluid spinning system of the invention may show different configurations of circuits, different sizes and very diverse combinations of intake nozzles, stretching zones caused by the Venturi effect, doubling and twisting areas for fibers and yarn in function of the kind of material and sizes of the yarn to be produced, while the described embodiment does not involve any limiting condition of its scope.
