Definitions

  • the invention relates to melt-spun monofilaments made of polyamide, polyester or polypropylene as thread-forming polymers with improved abrasion resistance and their use for the production of technical fabrics or use as wire.
  • thermoplastic polymers The processes for producing monofilaments from thermoplastic polymers are known in principle and e.g. described in Handbuch der Kunststofftechnik II, C. Hauser Verlag, Kunststoff 1986, pages 295 to 319.
  • thermoplastic polymers can be improved by adding polyethylene / polypropylene rubber.
  • the polymer mixtures of thermoplastic polymers and modified polyethylene / polypropylene rubber are known to be compounded and granulated on twin-screw extruders and processed by injection molding.
  • the invention has for its object to improve the abrasion resistance and the alternating bending resistance of melt-spun monofilaments and their processability to technical fabrics or wire and thus e.g. to significantly extend the service life of technical fabrics.
  • the monofilaments according to the invention are distinguished by a permanently improved abrasion resistance, improved resistance to alternating bending stress and reduced thermal shrinking forces.
  • Another object is the use of the monofilaments according to the invention for the production of technical textiles, such as fabrics and felts for industry, e.g. Classifying fabrics, screen printing fabrics, shaped screen fabrics and press felts for paper and cellulose fiber production.
  • technical textiles such as fabrics and felts for industry, e.g. Classifying fabrics, screen printing fabrics, shaped screen fabrics and press felts for paper and cellulose fiber production.
  • the monofilaments according to the invention are produced by melt extrusion processes known per se.
  • the raw materials are either a mixture of granules or used as granules / powder mixture or as compounded granules. It is important to ensure that the components are mixed homogeneously in the melt and thus ultimately in the monofilaments. This is achieved using commercially available dynamic mixers after extrusion.
  • the aim was to increase the impact strength of the polymers and the transverse stability of the monofilaments obtained from the polymers.
  • Another object of the invention is the use of the monofilaments according to the invention for the production of technical textile fabrics or of technical wires, in particular lawn mower wire.
  • the monofilaments according to the invention are preferably used in so-called technical textiles such as fabrics and felts for industry, e.g. Classifying fabrics, screen printing fabrics, shaped screen fabrics and press felts for paper and cellulose fiber production.
  • the preferred thread-forming thermoplastic polymer for the production of the monofilaments is polyamide, in particular polyamide (PA) 6, 6.6, 6.10, 6.12, 11 and 12, mixtures of the polyamides or copolymers thereof.
  • Preferred polyesters are polyethylene terephthalate (PET) or polybutylene terephthalate (PBT).
  • the mixture according to the invention can contain up to 15% by weight, based on the sum of components a), b) and c), plasticizers, for example caprolactam for polyamide, phenols, arylsulfonamides or phthalic acid esters, pigments, for example TiO 2 , carbon black, dyes, as additional additives internal lubricants, for example alkaline earth stearates, in particular of Ca or Mg, waxes to increase transparency, for example those based on fatty acid amides, can be added.
  • plasticizers for example caprolactam for polyamide, phenols, arylsulfonamides or phthalic acid esters
  • pigments for example TiO 2 , carbon black
  • dyes as additional additives internal lubricants, for example alkaline earth stearates, in particular of Ca or Mg, waxes to increase transparency, for example those based on fatty acid amides, can be added.
  • Examples 1 to 5 show monofilaments according to the invention, example 6 a comparative example.
  • a medium-viscosity semi-crystalline maleic anhydride modified PE / PP rubber was used as the modified rubber (component B).
  • Component C) is a commercially available aging stabilizer Irganox 1098 from Ciba Geigy, a sterically hindered phenol of the formula (I) N, N'-hexamethylene-bis- (3,5-di-tert-butyl-4-hydroxy-hydrocinnamic acid amide)
  • the concentrations of component A) were varied between 98.25% by weight and 84.5% by weight of component B) between 1.25% by weight and 15% by weight.
  • the concentration of component C) was kept constant at 0.5% by weight
  • the components A), B) and C) were degassed as granules or granule powder mixture in accordance with the desired concentration ratio on a single-screw extruder under vacuum, then melted at 270 ° C. and then mixed together in a dynamic mixer, so that components A), B ) and C) were homogeneously mixed finely dispersed.
  • the monofilament was then produced in a manner known per se on a monofilament spinning and drawing machine.
  • the filament-forming polymer melt was spun from a device for melt spinning monofilaments to cool in a water bath at 20 to 30 ° C, then stretched 3.5 times in hot water at 80 ° C and in hot air at 150 ° C and finally in Hot air fixed at 210 ° C.
  • the preparation is carried out analogously to the spinning process shown above.
  • the abrasion tests were carried out on the test bars produced from the monofilaments using the AT 2000 abrasion tester from Einlehner in calcium carbonate / water suspension.
  • a ceramic slat rotating body consisting of 16 circularly arranged round bars made of Al-oxide ceramic with a flat ground surface touching the screen was used as the wear body.
  • the arrangement corresponds approximately to the open and closed surfaces of a flat suction device in a paper machine.
  • the material loss of the respective test sieve is determined from the difference between the rubbed and non-rubbed sieve surface as a loss of weight and thickness.
  • Table 2 shows further Examples 7 to 10, in which a hydrolysis-stabilized high-molecular polyethylene terephthalate (PET) with a maleic anhydride-modified polyethylene / propylene rubber (Exxelor VA 1803) and a hydrolysis stabilizer (Stabaxol P100) was used instead of polyamide.
  • PET polyethylene terephthalate
  • Exxelor VA 1803 maleic anhydride-modified polyethylene / propylene rubber
  • Stabaxol P100 hydrolysis stabilizer
  • the loss of length after the concrete edge impact test was determined. The loss of length decreases with increasing proportion of rubber modified with maleic anhydride.
