Definitions

  • the present invention relates to a process of manufacturing fibers from thermoplastic materials, particularly glass fibers, in which the material in a molten state is supplied to a hollow rotating body provided with orifices in the peripheral wall thereof and is projected through these orifices under the action of centrifugal force.
  • the invention relates particularly to the process of the following type wherein the threads of viscous material which are projected from the orifices, which are arranged in a plurality of superposed rows, are acted on by gaseous currents which subject these threads to a drawingout operation or attenuation to transform them into fibers.
  • gaseous currents are produced by an annular combustion chamber disposed coaxially with the rotating 'body from which the gaseous currents are discharged through a circular slot or expansion orifices which are situated at a level higher than the upper part of the wall of the rotating body in which the projection orifices are provided.
  • hollow rotating bodies having a large number of rows of projection orifices, twenty or more rows, are utilized, which in turn make necessary peripheral walls or bands of relatively great height.
  • the peripheral band is maintained at a substantially constant temperature along its entire height, and the diameters of the orifices decrease in size from the upper part of the band to the lower part.
  • fibers of substantially equal diameter are obtained, in spite of the decrease in temperature and speed of the gaseous currents which draw them out, since the smaller the diameters of the threads, the easier it is to draw them out, it being understood that the viscosity of the material is constant for all the threads, this condition being fulfilled by imparting a constant temperature to the peripheral band over its entire height.
  • the process according to the invention also makes possible the production of a large preponderance of fine fibers in comparison to those of larger diameters. These fibers, being no longer stuck together, result in products particularly pliable to the touch, very homogeneous, and with improved resistance to traction or greater tensile strengths.
  • the tensile strength of fibers is increased as a result of the process of the invention. In fact, during drawing-out, they no longer traverse sluggish flames or smoke at low temperature, but, on the contrary, they are maintained in an active field at a temperature and speed higher than that of the gaseous currents which draw them out.
  • the band of the rotating body is maintained at a substantially constant temperature by heating its lower part through induction by means of high frequency current.
  • the melted glass feeding the orifices of the peripheral band of the rotating body is given a viscosity of the order of at least 2500 poises, and particularly 3000 poises.
  • the diameter of the orifices of the band is then increased, this diameter being generally not less than 0.9 mm.
  • the glass thus undergoing fiberizing being at lower temperature, the result is that the life of the centrifuge bodies is increased. Moreover, the glass being projected through orifices of relatively greater diameter, the fibers obtained are longer, hence more elastic, and consequently'the products manufactured from these fibers have a greater capability of regaining the initial volume after compression. They can then be stocked or shipped while being maintained under a reduced volume.
  • the fiberizing of glass at a higher viscosity also permits the use of cheap glass compositions.
  • FIG. 1 is a vertical sectional view of an assembly to which the invention is directed;
  • FIG. 2 is a schematic illustration of the trajectories of the fibers when the orifices in the peripheral wall of the centrifuge shown in FIG. 1 are of uniform diameter;
  • FIG. 3 is a schematic illustration of the trajectories of the fibers when the orifices in the peripheral wall of the centrifuge shown in FIG. 1 are of decreasing diameter from the upper part to the lower part of the wall;
  • FIG. 4 is a graph illustrating the distribution of the fibers of different diameters resulting from the mode of operation illustrated in FIG. 2;
  • FIG. 5 is a graph illustrating the distribution of the fibers of different diameters resulting from the mode of operation illustrated in FIG. 3;
  • FIG. 6 is a vertical sectional view of another embodiment of the invention which includes a deflecting screen for controlling the trajectory of the fibers produced by the assembly;
  • FIG. 7 illustrates the trajectory of the fibers by the use of the arrangement shown in FIG. 1;
  • FIG. 8 illustrates the trajectory of the fibers by the use of the arrangement shown in FIG. 6.
  • the centrifuge body 1 rotating at high speed about its vertical axis is provided with a peripheral band or wall 2 in which are provided rows of orifices 3 through which the melted material fed to the interior of hollow body 1 is projected in the form of threads.
  • a distributor member or organ 4 in the shape of a basket into which the melted material is fed.
  • Orifices S are provided on the vertical lateral wall of the basket through which the material is projected so as to form a layer of substantially uniform thickness over the entire inner surface of band 2.
  • An annular combustion chamber 6 is arranged coaxially with the rotating body and is provided with a slot 7 or a plurality of expansion orifices through which the combustion gases escape at high speed and high temperature and come in contact with the threads of material projected from the orifices 3 and which give rise to their drawing-out into fine fibers.
  • a 'Winding 8 is also provided which is traversed by a high-frequency current for induction heating of peripheral band 2.
  • This induction heating of the lower part of the band 2. has the effect of maintaining the latter at a substantially uniform temperature over its entire height.
  • the diameters of orifices 3 are variable, according to the rows to which they belong, these diameters decreasing from the top of the band toward its lower part. This decrease in diameter may be progressive. However, practically, for reasons of machining, this decrease may be arranged in steps. In this way, for a peripheral band with twenty rows of'orifices, the distribution of diameters according to rows may be as follows: the first two rows of orifices at the upper part of the band may have a diameter of 1.1 mm.; the next fourteen rows of orifices at the central part of the band may have a diameter of 1.0 mm.; and the last four rows of orifices at the lower part of the band may have a diameter of 0.9 mm.
  • FIG. 2 illustrates schematically the path of fibers 9 arising from threads projected by the rotating body provided with projection orifices of the same diameter. It is seen that the fibers derived from the threads issuing from the upper row A collide with the fibers derived from threads of an intermediate row B, the latter, in turn, intersecting the fibers derived from threads of lower row C.
  • FIG. 3 portrays schematically the functioning of the device according to the invention with decreasing orifice diameters.
  • This drawing shows the path of fibers from levels A, B, C identical to the preceding FIG. 2. It is seen that there is no longer any intersection of the fibers.
  • Curve 10 of FIG. 4 shows the distribution R of the fibers of different diameters D in microns, resulting from the mode of operation indicated in FIG. 2.
  • the corresponding curve 10a of 'FIG. shows the distribution of the fibers of different diameters resulting from the mode of operation in accordance with the invention as illustrated in FIG. 3. It is seen that the fibers obtained by the latter procedure have a much more regular diameter and that the fine fibers are in greater number.
  • the device according to the invention comprises, in addition, an annul ar screen 11 disposed coaxially with the rotating body and located under the annular combustion chamber 6, with the lower part of this screen being substantially at the level of the firs-t row of orifices of the rotating body.
  • This screen is hollow and is traversed by a cooling fluid.
  • An annular blower 12 is disposed concentrically with the screen 11, and the blower crown 12 is provided with exit orifices 13 which are adapted to direct a fluid current in surrounding relation to the produced fibers.
  • a blower crown may also be provided in the device of FIG. 1 overlying the interior of the induction heater 8.
  • the presence of screen 11 has the efiect, on one hand, of contributing to the homogenization of temperature of the peripheral band 2 and, on the other hand, of increasing the speed of the gaseous current acting on the threads or streamlets of material. It also has the effect, due to the expansion of combustion gases between the band 2 and the lower part of the screen, of spreading out the trajectories of the streamlets and ultimate fibers in a horizontal direction.
  • FIG. 7 illustrates the angle a formed by the tangent to the trajectory of a fiber 9 issuing from band 2, with respect to the vertical, when the device does not include a screen 11, and in comparison thereto,
  • FIG. 8 shows the angle ,8 formed by the tangent to the trajectory of a fiber at a corresponding point, in the case where the assembly includes a screen 11 as illustrated in FIG. 6.
