  • thermal shrinkage Another measure of the dimensional stability of synthetic threads is thermal shrinkage: at high temperatures, the mobility of the molecular chains increases. The higher the chains are oriented, the higher is the shrinkage of the thread.
  • the sum of the elongation and the shrinkage is less suitable for this because it is subject to certain fluctuations.
  • the strain at a given force called a reference strain is selected. In English one speaks of the EASL (Elongation At Specific Load).

HMLS monofilaments have also been proposed for this use.
  • the spinning distortion and the crystallization are influenced by the viscosity of the polymer, the type of polymer, crosslinking agent, other possible additives and the cooling process below the spinneret, as shown in numerous documents.
  • Monofilaments intended for use in the construction sector should be flame-retardant and must contain certain additives, such as dyes and preferably also stabilizers.

  • the pigments may e.g. in the form of dry pigments, liquid pigments, encapsulated pigments, pigment dispersions or most preferably in the form of a masterbatch with a carrier polymer, for example a polyolefin, a thermoplastic polyester or a thermoplastic elastomeric polymer.
  • the incorporation of the pigment into the thermoplastic polyester can be carried out by various methods described in the prior art. These include e.g. mixing the pigment with the polyester or dissolving and / or dispersing the pigment in the polyester.

  • the masterbatch is introduced into the polyester matrix during the production of the monofilament.
  • the pigment molecules color the monofilament.
  • the pigment on the one hand dyes the monofilament, on the other hand, absorbs heat radiation only to a limited extent and reflects the main part of the irradiation, so that the monofilament heats up less by irradiation of sunlight than would be the case when coloring with carbon black.
  • the monofilaments according to the invention are flame-retardant.
  • the flame retardancy is another important property of the monofilament according to the invention.
  • Appropriately equipped monofilaments are used for reasons of fire protection in the construction sector.

  • Particularly preferred such friction-reducing additives are incorporated in the form of a masterbatch in the monofilament.
  • Polyolefins, such as polyethylene or polypropylene, or polyesters, such as polyethylene terephthalate or polybutylene terephthalate, are used in particular as the carrier.
  • Particularly suitable fatty acid amides are amides of saturated or unsaturated carboxylic acids having from six to twenty carbon atoms. Preference is given to using oleic acid amide, in particular in combination with other fatty acid amides.
  • the polyester matrix of the monofilament is constantly fatty acid amide, in particular Oleic amide, since its surface energy is greater than that of polyester. This leads to a permanent lowering of the wettability of the polyester surface, which leads to a reduction of soiling by liquids.
