Definitions

  • the invention relates to a melt-extruded monofilament for use in technical textiles, especially in paper machine clothing, essentially made of a plastic material consists.
  • melt-extruded monofilaments have high strength and are therefore preferred in strength-bearing Structures such as technical fabrics and knitted fabrics and in particular used in clothing for paper machines.
  • the object of the invention is therefore a monofilament for textile To create materials of the type mentioned, the extrudable in a simple manner and at lower temperatures and can be fixed later.
  • the plastic material can only be made of Polytrimethylene terephthalate exist.
  • the plastic material to increase the Abrasion resistance, however, especially elastomeric polyurethane (PU) up to a proportion of 45 wt .-%.
  • PU elastomeric polyurethane
  • this Case has the use of PTMT materials according to the invention the further advantage that the in the manufacture and treatment occurring temperatures are so low that they do not damage the polyurethane and therefore the Technology provided protective measures can be omitted, which also contributes to cost reduction.
  • the plastic material a hydrolysis stabilizer in a manner known per se contains, preferably up to a proportion of 5% by weight.
  • the melt-extruded monofilaments according to the invention can have any cross-sectional shape, ie they can be, for example, rectangular, cloverleaf-shaped, dog-bone-shaped, star-shaped, round, oval or the like and in particular also have a hollow cross-section.
  • the cross-sectional area of the monofilaments is preferably between ⁇ , ⁇ 2 mm 2 and 3.5 mm 2 , which corresponds to a diameter of ⁇ , ⁇ 8 to 1 mm with a round cross section.
  • the PTMT material can, for example, by condensation of Teraphthalic acid and 1,3-propanediol.
  • PTMT materials are already known per se and also have already been used for the production of fibers. The one there However, the specific strength achieved was for the area of application in strength-bearing structures such as technical fabrics and knitted too little. It was all the more surprising, that the PTMT-based monofilaments of the invention for use in such technical textiles and in particular Paper machine clothing has sufficient strength.
  • melt-extruded according to the invention could Monofilaments also significantly higher degrees of stretching be achieved than in the literature for fibers PTMT base is specified.
