Definitions

  • the invention relates to a method and a device for manufacturing a composite yarn formed by the association of a multiplicity of continuous glass filaments and continuous filaments of thermoplastic organic material.
  • the manufacture of such a composite wire is described in patent application EP-A-0 367 661.
  • This document describes installations comprising a die, from which continuous filaments of glass are drawn, and a spinning head, supplied under pressure by a thermoplastic organic material, delivering continuous organic filaments.
  • the two types of filaments can be in the form of sheets, or of sheet and thread, during assembly.
  • An advantageous embodiment described in this document consists in surrounding the filaments or the glass wire with the organic filaments when they are joined.
  • a composite wire thus produced has the advantage of protecting the glass filaments from friction on the solid surfaces with which the composite wire comes into contact.
  • this arrangement does not promote perfect homogenization of the mixture of the two types of filaments. Indeed, a straight cut of the composite yarn shows preferred areas for each type of filament, which can be a sought-after method of assembly, for certain
  • these composite wires have a corrugation. This is obvious when the sons are in the form of coils because the coils undulate over their entire periphery. This undulation of the composite wire is in fact due to a phenomenon of withdrawal of the organic filaments which results in an undulation of the glass filaments. This phenomenon has various drawbacks. First of all, it requires thick cuffs for the production of the coils so that they support the hooping exerted by the composite wire. In addition, the unwinding of the reel becomes very delicate due to the geometry modifications. This presentation of the wire can however be advantageous when, for example, it enters the structure of a fabric which will later be used to reinforce a curved piece.
  • the subject of the invention is a process for manufacturing a composite wire which does not have any ripple during its formation and which remains stable over time.
  • thermoplastic filaments within a composite wire which contains glass filaments are solved by a manufacturing process, of a composite wire formed by the association of continuous glass filaments coming from a die. and continuous filaments of thermoplastic organic material from a spinning head in which the thermoplastic filaments are mixed in the form of a sheet with a bundle or sheet of glass filaments after having been heated to a temperature above their transformation temperature , stretched and then cooled very quickly. The stretching thus carried out hot makes it possible to modify the structure of the thermoplastic filaments which are cooled in this new state. After the association of the thermoplastic filaments thus treated, with the glass filaments, the thermoplastic filaments do not no longer show any withdrawal. According to a preferred embodiment of the invention, the thermoplastic filaments are guided in the form of a sheet up to the glass filaments and are mixed with them at identical speeds on the generator of a roller.
  • thermoplastic filaments It is also possible to impart a higher speed to the thermoplastic filaments. To mix the two types of filaments, it is then preferable to spray the thermoplastic filaments in the form of a sheet in the bundle or sheet of glass filaments.
  • thermoplastic filaments are projected with a speed greater than the drawing speed of the glass filaments
  • an entanglement of corrugated thermoplastic filaments is obtained in the middle of linear glass filaments. It is thus possible to obtain a more or less bulky composite yarn which can in particular be used for the manufacture of fabrics.
  • Another advantage of this process is to ensure a homogeneity of the composite yarn greater than that obtained by manufacturing processes consisting in drawing a glass fiber or a sheet of glass filaments surrounded by thermoplastic filaments.
  • the invention also proposes a device allowing the implementation of this method.
  • this device comprises on the one hand an installation comprising at least one die, supplied with glass, the lower face of which is provided with a multiplicity orifices, this die being associated with a coating roller, on the other hand another installation comprising at least one spinning head supplied under pressure with molten thermoplastic material, the lower face of which is provided with a multiplicity of orifices, this spinning head being associated with a stretcher, of the drum type, with heating and cooling means and with a means making it possible to mix the thermoplastic filaments with the glass filaments, finally means common to the two installations allowing the assembly and the winding of the composite wire.
  • the drum stretcher has at least three groups of drums ensuring an increasing linear speed of the thermoplastic filaments.
  • the first group composed for example of two drums, corresponds to a heating zone.
  • the second group is composed for example of two drums driven at speeds higher than those of the previous drums.
  • the third group composed for example of two drums driven at speeds identical to those of the last drum of the second group, corresponds to a cooling zone.
  • thermoplastic filaments remain in contact with them for a sufficiently long time to modify their structure.
  • temperature rise obtained must be uniform and identical for all the filaments so that their structure is identical after passing over the stretcher.
  • the in particular electric heating means are placed at least in the first drum of the stretcher encountered by the thermoplastic filaments. In this way, the heating of the thermoplastic filaments is done by contact on at least one heating drum. It is thus fast and uniform.
  • the cooling means must also act very quickly so as to freeze the thermoplastic filaments in their new structure.
  • thermoplastic filaments Their size, number and arrangement are chosen such that the thermoplastic filaments remain in contact long enough to freeze their structure.
  • thermoplastic filaments are preferably done by circulation of a fluid at least in the last drum of the stretcher.
  • the means for mixing the two types of filament can be constituted by the association of two rollers.
  • a first “guide” roller optionally a motor, directs the sheet of thermoplastic filaments towards a second roller.
  • the thermoplastic filaments mix with the glass filaments, also in the form of a sheet.
  • This device has the advantage of creating an intermingling of the filaments, the latter arriving with identical speeds.
  • the mixture of filaments obtained then contains only linear filaments.
  • thermoplastic filaments are linear and whose thermoplastic filaments have an undulation.
  • a device implementing the properties of fluids which can be liquids or gases such as pulsed or compressed air. It may for example be a venturi device, which makes it possible to project the thermoplastic filaments into a sheet or bundle of glass filaments, even if the thermoplastic filaments have a speed greater than that of the glass filaments.
  • the drum stretcher In order to obtain a higher speed of the thermoplastic filaments, the drum stretcher must communicate with the filaments thermoplastics a speed higher than the drawing speed of the glass filaments.
  • the devices thus described allow the production of composite yarns, from glass filaments and thermoplastic filaments, which do not present any deformation thereafter, that is to say that there is no longer any withdrawal of the thermoplastic filaments .
  • Such devices also have the advantage of being able to be produced on the same level, unlike certain installations of the prior art. For this, it is possible to have a deflection element such as a roller between the spinning head of organic material and the drum stretcher.
  • FIG. 1 is shown a schematic view of a complete installation according to the invention.
  • a die 1 supplied with glass either from the front of a furnace which directly carries the molten glass to its top, or by a hopper containing cold glass, for example in the form of balls, which falls by simple gravity.
  • the die 1 is usually made of platinum-rhodium alloy and heated by the Joule effect so as to melt the glass or to maintain it at a high temperature.
  • the molten glass then flows in the form of a multitude of threads drawn in the form of a bundle 2 of filaments, by a device, not shown which also makes it possible to form the coil 3, on which it will be returned by the after.
  • These filaments 2 then pass over a coating roller 4 which deposits a primer or sizing on glass filaments.
  • This size may include compounds, or their derivatives, constituting the thermoplastic filaments 5 which will come to associate with the glass filaments to form a composite yarn 6.
  • FIG. 1 is also shown schematically a spinning head 7 from which the thermoplastic filaments 5 are extruded.
  • the spinning head 7 can be supplied with a thermoplastic material, for example of the polypropylene type, stored for example in the form of granules which is melted and then flows under pressure through multiple orifices placed under the spinning head 7, to form the filaments 5 by drawing and cooling.
  • the filaments are cooled by forced convection, by a conditioning device 8 of shape adapted to that of the spinning head 7 and which generates a laminar air flow perpendicular to the filaments.
  • the cooling air has a constant flow, temperature and humidity.
  • the filaments 5 then pass over a roller 9 which makes it possible on the one hand to gather them in the form of a sheet 10 and on the other hand, to deflect their trajectory.
  • a roller 9 which makes it possible on the one hand to gather them in the form of a sheet 10 and on the other hand, to deflect their trajectory.
  • the die 1 and the spinning head 7 on the same level and therefore to be able to produce composite wires on sites where hitherto only glass wires were produced, without requiring large modifications if not the installation of a wiring position for thermoplastic.
  • the devices already proposed for the production of composite yarns generally require an arrival of the yarn or the sheet of glass filaments above the thermoplastic die and therefore an installation of the glass die on a higher level. This generally leads to a total modification of the structures.
  • thermoplastic filaments After passing over the roller 9, the sheet 10 of thermoplastic filaments passes over a drum stretcher 11 formed for example of six drums 12, 13, 14, 15, 16, 17.
  • drums 12, 13, 14, 15, 16, 17 have different speeds so that they create an acceleration in the direction of travel of the thermoplastic filaments.
  • These drums are also associated with the heating and cooling which are not shown in the figures. In the case shown, the drums can for example operate in pairs.
  • the drums 12, 13 are then associated with a heating device. This device is for example an electrical system which provides a homogeneous and rapid rise in temperature of the thermoplastic filaments because the heating takes place by contact.
  • These drums 12, 13 are driven at a speed, identical for both, which allows the stretching of the thermoplastic filaments from the spinning head 7.
  • the second pair of drums 14, 15 is driven at a speed greater than that of the first pair.
  • the thermoplastic filaments heated during their passage over the first pair of drums to a temperature defined by the nature of the thermoplastic material undergo an acceleration due to the difference in speeds between the two pairs of drums. This acceleration leads to an elongation of the thermoplastic filaments which modifies their structure.
  • the last pair of drums 16, 17 is driven at a speed identical to that of the previous one and includes a cooling device for example of the "water-jacket" type which allows the filaments to be frozen in their new state.
  • thermoplastic filaments must be carried out quickly and uniformly.
  • the choice of means contributes to this as we saw above.
  • the invention consists of a treatment of filaments and not of threads as is customary to do.
  • the heating and cooling of the filaments can be carried out more quickly and more homogeneously than if it were the treatment of a wire, due to the heat exchange surface per greater quantity of material.
  • the stretcher 11 can also consist of more drums while respecting the three zones previously described: heating, stretching, cooling.
  • each of these zones can consist of a single drum. It is also possible that these three areas are repeat several times, that is to say that the thermoplastic filaments after having undergone the treatment described above can again be treated one or more times by successive passages in zones of the same type by renewing each time the process: heating , stretching, cooling.
  • thermoplastic filaments slide between the rollers of the stretcher, on which the thermoplastic filaments slide. It is thus possible to increase the contact times allowing the heat exchanges either for the heating stage or for the cooling stage.
  • thermoplastic filaments then passes over a “guide” roller 18, optionally a motor, and a “presser” roller 19.
  • the thermoplastic filaments are then mixed with the glass filaments so that the junction of the two plies takes place on a generator of the “presser” roller 19.
  • This mixing device makes it possible to clearly define the geometry of the sheet of thermoplastic filaments and therefore allows very homogeneous mixing.
  • All of the glass and thermoplastic filaments then pass over a device 20 which allows the assembly of these filaments to form a composite wire 6.
  • This composite wire 6 is then immediately formed into a coil 3 by a device not shown which allows the drawing of glass filaments at a given linear speed, kept constant to guarantee the desired linear mass.
  • FIG. 2 This other device is shown in Figure 2. This figure only shows the device for mixing the two types of filaments. The rest of the device remains identical to FIG. 1. An essential difference, but not shown, is that the speed communicated to the ply of thermoplastic filaments, by the stretcher 11 and more precisely by the drums 14, 15, is no longer identical to the speed of drawing of the glass filaments. Indeed, in order to obtain corrugated thermoplastic filaments in the composite yarn, their speed must be greater than the drawing speed of the glass filaments, during mixing.
  • FIG. 2 shows the ply 10 of thermoplastic filaments after it has passed over the stretcher 11 which is not shown: the ply 10 which has therefore already undergone a treatment on the stretcher and which has the desired speed, passes on a deflection roller 21 then through a venturi system 22.
  • This device ensures the projection of the sheet 10 of thermoplastic filaments in the sheet 23 of glass filaments, while maintaining the individualized thermoplastic filaments.
  • the venturi device does not communicate any additional speed to the sheet 10 so that a minimum of compressed air is projected onto the glass filaments. In this way, the risks of disturbance in the glass filaments, due to the sending of compressed air in addition to the projection of thermoplastic filaments are minimized.
  • An element 27 can also be added to this device. It is a tray comprising a recess having a dimension allowing the passage of the sheet of glass filaments. This element 27 makes it possible in particular to preserve the geometry in the form of a sheet 10 of the filaments. thermoplastics after spraying and avoids the divergence of the thermoplastic filaments.
  • This element 27 is preferably made of a composite material of textile fabric and phenolic resin of the bakelite type, allowing the filaments to slide.
  • thermoplastic filaments are projected into a sheet of glass filaments after it has passed over the sizing roller 4. It is also possible to project the thermoplastic filaments into the bundle 2 of glass filaments, that is to say that is to say before passage of these on the sizing roller 4. The homogeneity of the mixture of filaments obtained may be greater in the latter case.
  • thermoplastic filaments being projected into the sheet or bundle of glass filaments, the two types of filaments mix to form a composite wire on a device 20 identical to that of FIG. 1.
  • FIGS. 3 a, b, c are diagrammatically shown straight sections of composite wires obtained by different methods.
  • Figure 3a is a representation of a section of a composite wire obtained according to the invention. A homogeneous distribution of the thermoplastic filaments 25 and the glass filaments 26 is observed. Good homogenization of the composite yarn leads to better cohesion of the composite yarn.
  • FIGS. 3b and 3c represent straight sections of composite yarns obtained by other methods such as the use of an annular thermoplastic die, or by association of yarn with ply (figure 4b), or by tablecloth to tablecloth association (Figure 4c).
  • the distribution of the filaments is less homogeneous and the core of the wire is a privileged area for the glass filaments 26 ', 26''while the thermoplastic filaments 25', 25 '' are more on the periphery. Note that the tablecloth to tablecloth assembly results in better homogenization.
  • the sizing solution can contain a photo-initiator, capable of initiating a chemical transformation of the sizing under the action of actinic radiation.
  • a photo-initiator capable of initiating a chemical transformation of the sizing under the action of actinic radiation.
  • Such a size makes it possible to further increase the cohesion of the composite yarn.
  • It can also be a thermal initiator which is implemented by a heat treatment.
