Definitions

  • the invention relates to fibers, non-woven fabrics or fiber piles based on polyphenylene sulfide and methods for producing such products.
  • PPS fibers polyphenylene sulfide fibers
  • EP 171 021 fibers and filaments are produced from the polyarylene sulfides belonging to the polyphenylene sulfide group by melt spinning.
  • melts When working with PPS melts, it has also been found that such melts easily oxidize on the surface, which affects the product quality of the fibers produced by melt spinning.
  • polymer fibers based on PPS with an average fiber diameter of ⁇ 6 ⁇ m, preferably 0.2 ⁇ m to 6 ⁇ m are produced in that the polymer melt streams flow through an essentially parallel along a zone of 2 mm to 100 mm, preferably 2 mm to 50 mm, and at a lateral distance of 2 mm to 30 mm from the outlet bores sound or supersonic velocity reaching gaseous medium are extracted and cooled below the melt temperature, with simultaneous deformation and cooling amorphous fine or finest fibers of finite length arise, which are laid down to form a nonwoven or fiber pile.
  • melt streams are additionally substantially longitudinally by the action of one on the melt streams in a zone of 1 mm to 30 mm, preferably 2 mm to 10 mm, in connection with the outlet bores acting static pressure drop.
  • the fiber formation process is based on the one hand on a direct pressure drop and on the other hand on the acceleration due to the gaseous medium flowing in parallel.
  • the fibers produced in this way based on PPS obey a narrow Gaussian distribution with a coefficient of variation ⁇ 50%, preferably between 10% and 35% and a strength of 0.4 to 1.1 GPa and without thermal fixation have an elongation of 20 to 80% and, after thermal fixation under tension, a strength of 0.6 to 1.1 GPa and an elongation of 10% to 30%.
  • the process for producing such PPS fibers is characterized according to the invention in that polymer melt streams based on PPS emerging from spinning bores under the action of an inert gas flowing in parallel therewith at a temperature of 20 ° C to 280 ° C, preferably 80 ° C to 200 ° C, drawn out to finally long fine fibers and cooled below the melt temperature.
  • the fibers are expediently thermally fixed by the action of the hot inert gases immediately after the fiber formation process.
  • the fibers emerging from the drawing nozzle can subsequently be thermally fixed in several stages, preferably by thermal fixing by means of calenders or by inert gases at a temperature of 80 ° C. to 260 ° C.
  • the mechanical properties of the new PPS fibers are superior to the known PPS fibers. In particular, they have a higher tear resistance. These favorable properties are probably due to the fact that oxidation processes during spinning can largely be avoided due to the high cooling rate in the drawing nozzle.
  • PPS granules 2 are melted at a temperature of 320 ° C. by means of the extruder 1 and fed to the spinneret 5 at a pressure of 6 bar by means of the spinning pump 3 via the melt filter 4.
  • the melt has a viscosity of 50 Pas at this temperature.
  • the melt emerging from the outlet bores 6 of the spinning nipples 7 (FIG. 2 and FIG. 3) is drawn into very fine fibers in the gas-dynamic pulling nozzle 8 arranged below the spinneret 5 and deposited in the collecting chamber 9 on a conveyor belt 10 to form a nonwoven fabric 11.
  • a detailed explanation of the construction and the mode of operation of the drawing nozzle 8 can be found e.g. in EP 38 989 and EP 66 506.
  • a pressure drop along the axis of the drawing nozzle which is generated in a known manner by driving jets 12 (FIG. 2).
  • Compressed air with a temperature of 50 ° -100 ° C and a static pressure of 10 bar is used as the blowing agent, which is supplied via the connections 13.
  • Propellant and suction gas are drawn off below the storage chamber 9 and the conveyor belt 11 through the suction box 15.
  • the temperature of the spinneret 5 is kept constant at a value in the range from 300 ° C to 350 ° C.
  • the mass throughput per spinning bore is 2.5 g / min.
  • the fibers 11 obtained in this way have the fiber diameter distribution shown in FIG. 4 with an average fiber diameter of 4.1 ⁇ m and a coefficient of variation of 33%.
  • the ordinate is the sum of the frequencies of all occurring fiber diameters, each of which is below a fiber limit diameter shown on the abscissa. From this it can be seen that fibers with a diameter of ⁇ 2 ⁇ m and> 8 ⁇ m practically no longer exist.
  • Example 2 Also with the same apparatus and under the same conditions as in Example 1, a nonwoven fabric was produced, which was subjected to thermal fixation with hot inert gas after the fiber deposition. The fleece was exposed to temperatures of Exposed to 80 ° C to 260 ° C. These measures were also used to prevent material shrinkage.
  • the drawing nozzle method used in the above-described exemplary embodiments can also be modified in such a way that the melt flow is first defibrated by a high static pressure drop and then extracted again by a gas stream flowing in parallel (see FIG. 3).
  • the spinneret 5 forms a closed system together with the downstream drawing nozzle 8.
  • the melt 16 is fed to the spinning nipple 7 with the outlet bore 6 via a melt filter.
  • a sealed (18) closed pressure chamber 19 is arranged between the lower edge of the spinneret 5 and the upper edge of the drawing nozzle 8 in a rotationally symmetrical manner about the axis.
  • the pressure chamber which is closed on all sides, can be supplied with inert gas 20 under pressure.
  • the inert compressed gas was introduced into the pressure chamber 19 at a temperature of 350 ° C. and at an absolute pressure of 10 bar.
  • the fiber formation 17 then takes place directly in the pressure gradient and, furthermore, due to the gas flow resulting from the pressure gradient (greatest pressure in the pressure chamber 19) in the Laval nozzle 21 following the pressure chamber and the subsequent impact diffuser 22 instead.
  • the laying of the fibers 17 to the fleece 11 takes place in the same way as in the device according to FIGS. 1 and 2. With the operating conditions described above, using this variant, very fine fibers with an average fiber diameter of 0.6 ⁇ m and a standard deviation of 0. 4 ⁇ m.
  • a further process variant for the production of the PPS fibers according to the invention consists in that the melt streams emerging from the spinneret are blown at high speed essentially in the flow direction in a subsequent open space (free space) by hot air.
  • the drawing nozzle or Laval nozzle following the spinneret can be omitted.
  • the process is known under the name "melt blown process” and is e.g. in detail in U.S. Patent 4,048,364. It is particularly suitable for processing low-viscosity melts.
  • polyphenylene sulfide in the form of granules was used as the starting material.
  • Particularly suitable are the polyarylene sulfides belonging to the group of polyphenylene sulfides, the production and properties of which are described in more detail in EP 171 021.
