Definitions

• the object of this invention is a new Spinning System within a fluid medium, which transforms the fibers into threads using a fluid medium in which the fibers are introduced, moved and transformed into yarn (spinning) by the control and variation of certain parameters of the fluid system and the control of the movement of the fibers to be spun, and they can also receive in said fluid medium a physical and / or chemical treatment of those known in the textile sector, simultaneously with the realization of spinning.
• the present invention consists of a system or machine that produces and treats threads from fibers through the establishment, variation and control of the static and dynamic parameters of the fluid into which the fibers have been introduced, which in turn causes effects. physical overlays, stretching, twisting, etc., in the fibers themselves.
• the system essentially has a set of fluid conduits in which it circulates in a closed circuit under pressure, inside which there are one or several holes in the system through which the fibers are introduced, dragged by a fluid in the fluid system; too
• SUBSTITUTE SHEET (RULE 26) there are one or several holes of the fluid circuit thread.
• This circuit has mechanisms for fluid delivery, for example pumps, so that all the variables that affect the fluid such as speed, flow, pressure, etc., can be modified and the inlet holes have the possibility of varying the surface of the passage section, which can also be performed at other points of the circuit, as well as the predetermined modification of the direction of the fluid current to cause the desired movements of the textile fibers.
• the spinning process occurs from the introduction of the fibers, dragged by a fluid medium, through one or several holes or injectors, perpendicular or oblique with respect to the axis of the conduction, within the closed circuit of fluid under pressure, from which moment they are made, in combination and programmed according to the type of wire to be obtained: parallel connections of different holes or injector injectors through which pressure fluid is admitted in the circuit (with fibers or without fibers ), effects of reducing the diameters of the holes to facilitate a Venturi effect, Venturi effects inside the conduits, connection between different conduits to achieve overlapping or bending of different fibers, and any other effects known in the art that are susceptible to be carried out by conventional means inside a fluid containing suspended solids (fibers). These effects include: dyeing, vaporizing, fixing or other possible treatments of the fibers and / or threads.
• auxiliary devices can be arranged that help parallel the fibers inside the fluid.
• These devices can be, for example, roughnesses (card fittings) that provide a mechanical aid within the fluid to parallel the fibers, fins, deflector plates, nozzles for introduction of pressurized air or other fixed or mobile elements that allow modifying at will the direction of the fluid stream.
• the twisting of the thread is done by applying various effects that may or may not be combined with each other and that can be applied simultaneously or in deferred phases of the process.
• the different effects and degrees of torsion are achieved through the application of conventional techniques well known in the fluid dynamics technique, whose controlled use deviates the fluid path and consequently that of the circulating fibers, a circular movement of the thread is generated on itself by creating a Coriolis effect, or any change of direction is made in any of the three directions of space (for example, 180 degrees of deviation, multiple changes of spiral direction, etc.), all for apply a controlled twist to the thread; This can be combined with specific changes in the section of the passage to internally cause Venturi effects and with the injection of more fibers at certain points.
• the torsion of the fibers occurs when the fibers are intertwined with each other, once they have been attached as parallel as possible to each other.
• this can be achieved either by the manipulation of solids (fibers) within the fluid and / or by the insertion of new fibers through additional injectors (with the possibility of Venturi effects or not), so that the fibers are interwoven and twisted.
• the yarn already bent and / or stretched and / or twisted is collected by a folding system that can be a conventional winding or other system already existing in the market.
• the type of fluid medium can be any of those used in industrial practice.
• a thread in known textile practice can also be reproduced in the fluid system of the invention by modifying the static and dynamic variables of the fluid system, as described above.
• a "flamed" thread can be made by stretching (Venturi effects or combination of those described above) in a programmed manner within the fluid medium.
• Other effects can be loops, serretas, knots, Lycra insertion, etc.
• conduits or conduits used to configure the circuit can be any and the drive and injection pumps as well as the control elements (pressure gauges, etc.) and Operations programming can form, together with the necessary injectors, subsystems that achieve the same ends in laminar or turbulent regime inside the duct.

• Figure 3 Scheme of a fluid system of the invention with three fiber inlet injectors and a wire outlet duct.
• Figure 4 Schematic view of fluid injection zone, with and without fibers.
• the fluid together with the textile fibers that it carries is introduced a set of pipes through the injectors 11, 12 and 13.
• the fluid injected in 11 is subjected to a Venturi effect in E1, upon entering the circuit C1, which causes a stretch of the transported fibers, the fluid with the fibers continuing its path to point 1 where the fluid with fibers stretched from 11 is incorporated into the current from 12.
• the fluid in this circuit C1 is driven by the pump B1.
• the fluid injected in 12 is subjected to a Venturi effect in E2, upon its entry into the C2 circuit, which causes a stretch of the transported fibers, the fluid continuing with the fibers its path to point 1 where it is incorporated into this the fluid flow with stretched fibers from 11 causing the gathering or bending of fibers from 11 and 12.
• the reduction of the section of the duct from 12 causes Venturi effect an additional stretching of the stretched and bent fibers from 11 and 12; then, the fluid flow with said fibers is incorporated into the horizontal lower zone of the conduit coming from 12 in an off-centered manner with respect to the axis of said conduit thus causing a swirling effect of the fluid which in turn causes a pretortion of the fibers in that point
• the fibers transported by the fluid reach point 2.
• the fluid in this circuit C2 is driven by the pump B2.
• the fluid injected in 13 is subjected to a Venturi effect in E3 upon its entry into the C3 circuit, which causes a stretch of the transported fibers, the fluid with the fibers continuing its path to point 2 where the fluid with folded fibers / stretched / pre-twisted from 12 is incorporated into the current again causing a meeting or bending of fibers and where also the reduction of the section of the duct from 13 causes Venturi effect an additional stretching of the fibers from 12 and 13; then, the fluid stream with said fibers is incorporated into the horizontal lower zone of the duct from 13 in an off-center manner with respect to the axis of said duct thus causing an effect swirling of the fluid which in turn causes a pretortion of the fibers at that point.
• the fibers transported by the fluid reach point 3 where Coriolis is caused by a rotation of the fluid which in turn causes a twist in the fibers, which have already been formed in the form of a stretched and twisted thread that is extracted from the conduction through the exit orifice to be subsequently wound or collected in any other conventional way.
• the fluid in this circuit C3 is driven by the pump B3.
• the spinning fluid system of the invention can have different circuit configurations, different dimensions and very different combinations of input injectors, stretch zones by Venturi effect, bending zones and twisting zones of fibers and yarn, depending on the type, material and dimensions of the yarn to be manufactured without the described embodiment assuming any limiting condition of the scope thereof.
