Definitions

  • the invention relates to monofilaments with rubber-elastic behavior, formed by extrusion with subsequent stretching from a thermoplastic polyether ester elastomer. These are flexible, somewhat stretchable monofilaments.
  • the invention has for its object a synthetic To create monofilament based on thermoplastic polyether ester elastomer with a rubber-elastic behavior, which should also have improved mechanical properties, in particular a high permanent temperature resistance.
  • this object is achieved in a generic monofilament by using a thermoplastic polyether ester elastomer which contains 5 to 50% by weight, in particular 25 to 42% by weight, of polyurethane as the elastomer component.
  • a thermoplastic polyether ester elastomer which contains 5 to 50% by weight, in particular 25 to 42% by weight, of polyurethane as the elastomer component.
  • polyether ester elastomers with a polyurethane component can be processed into monofilament threads by extrusion, which have good creep rupture properties with fatigue and hysteresis-free rubber elasticity.
  • polyetherester elastomers with a Shore hardness D of 46 to 63 are suitable for the extrusion of rubber-elastic monofilaments.
  • the monofilaments according to the invention have good rubber-elastic properties with fatigue-free rubber elasticity, high impact strength at low temperatures, high tear and abrasion resistance and high resistance to mechanical loads.
  • the monofilaments according to the invention are preferably made from a polyether ester elastomer from a block polymer of soft segments from polyalkylene ether diols and a polyurethane component from a mixture of diisocyanates and long-chain polyester or polyether diols.
  • Polyurethanes are produced by reacting (polyaddition) polyhydric alcohols, such as 1,4-butanediol polyether and polyesters with terminal OH groups, with polyhydric isocyanates.
  • Short-chain diols - hard segments - increase the hardness
  • long-chain polyols - soft segments - increase the elasticity of the polyurethanes.
  • the latter are as elastomer components in the selected polyether ester elastomers for the monofilaments according to the invention contain.
  • the monofilaments produced according to the invention from the polyether ester elastomer by extrusion have a high reversible elongation. Since the base material, thermoplastic polyester, has a high thermal resistance, a high permanent temperature resistance above 120 ° C., preferably above 130 ° C., can be achieved for the monofilament extruded according to the invention.
  • the extruded monofilaments are preferably stretched, in a ratio of about 1: 2 to about 1: 8. The degree of stretching depends on the application. Highly elastic monofilaments, i.e.
  • the monofilaments according to the invention are distinguished from known rubber threads by a smoother and harder surface, which increases their usability. In addition, they do not wear out so quickly.
  • Polyetherester elastomers are plastics known per se, which are used for the injection molding and rotational molding of molded parts and which are processed by extrusion to give films, sheets, tubes and tubes. So far it has not been possible to produce stretched monofilaments with diameters from 0.08 mm to 10 mm by extrusion.
  • the polyether ester elastomer optionally with the addition of additives from the group of stabilizers such as for increased heat resistance, UV resistance, hydrolysis resistance, colorants, at a temperature of about 210 to about 270 ° C in one Melt single-screw extruder and extrude to a monofil, and then stretch the monofil at a temperature of about 90 to 180 ° C in a liquid medium, preferably in water in a ratio of about 1: 2 to 1: 8.
  • polyether ester elastomers with the following selected property profile are particularly good Process monofilaments with excellent rubber-elastic and mechanical properties, in particular creep rupture properties: Property of polyether ester elastomer unit Test method Relative density 23/4 1.20 - 1.23 DIN 53479 Melting point 190 -213 ° C ASTM D 2117 Water absorption 24 hours in air from 23 ° C and 50% rel.
  • Polyetherester elastomers suitable for practicing the invention are, for example, the materials available from Akzo Plastics under the trade name Arnitel EM 480-630.
  • the extruded monofilament is stretched in two stages, in the first stage at temperatures of approximately 90 to 130 ° C. in a ratio up to a maximum of 1: 6 is then stretched at a temperature of about 130 to 180 ° C in a ratio of 1: 1.5 to a maximum of 1: 6.
  • the stretched monofilament is annealed at temperatures of 160 to 240 ° C. for a period of at least 5 seconds.
  • thermoplastic polyesters If it is desired to improve special properties, such as increased UV resistance, color, increased hydrolysis resistance, heat aging resistance or the like, this can also be achieved for the monofilaments according to the invention by adding suitable additives and stabilizers, as are known in the processing of thermoplastic polyesters .
  • the monofilaments that can be produced according to the invention are boil-proof and have a high chemical and thermal resistance, as well as high flex fatigue strength, high impact strength even at low temperatures, and high tear and abrasion resistance.
  • the monofilaments according to the invention can be processed excellently, in particular they are suitable for the production of industrial textiles by weaving, knitting or braiding to filter fabrics, elastic coating fabrics, membranes, elastic bands.
  • the smooth surface of the monofilaments, the textiles made from them can be subjected to high stresses, such as for conveyor and dry belts, filter fabrics for the chemical industry, support fabrics of needle felts are required.
  • FIG. 1 The invention is shown in FIG. 1 in a view of a monofilament and is explained below by way of example.
  • the stretched monofilament now obtained has a diameter of 0.25 mm. It has the following characteristics: Tear load: 15 N. Elongation at break: 60% Shrinkage in boiling water after 5 minutes: 3.5% Shrinkage at 160 ° C after 30 minutes: 10%
  • the shrinkage behavior can be improved by tempering the stretched monofilament at 160-240 ° C for 5-20 seconds.
  • the extruded stretched monofilament made of polyether ester elastomer produced according to the invention is distinguished by a smooth and hard surface and excellent rubber-elastic behavior with good mechanical properties. It is therefore ideally suited for the production of industrial textiles with rubber-elastic behavior as well as normal textile structures etc.
