Embodiment Construction

[0011] The polymeric material used to make the monofilaments comprises preferably 10% to 99.99% by weight, more preferably 50% to 99.8% by weight, and especially 80% to 99.5% by weight polyester. Also included are preferably 0.01% to 50% by weight of nanoparticles, more preferably 0.2% to 10% by weight and especially 0.5% to 5% by weight of nanoparticles. The proportion of other additives is preferably 0% to 60% by weight, more preferably 1% to 40% by weight, and especially 2% to 20% by weight.

[0012] The polyesters in the thermoplastic polymer material are preferably polyesters based on aromatic dicarboxylic acids and aliphatic or aromatic dihydroxy compounds.

[0013] Preferred polyesters are polyalkylene terephthalates, especially polyalkylene terephthalates having 2 to 10 carbon atoms in the alcohol moiety.

[0014] Such polyalkylene terephthalates are known per se and are described in the literature. Its backbone includes an aromatic ring derived from an aromatic dica...

Abstract

The invention relates to a method for producing at least one monofilament made of a thermoplastic polymer material containing at least one polyester and nanoparticles and optionally other additives as components, wherein the components are added to an extruder in partially or completely mixed form or separately, wherein the thermoplastic polymer material is first extruded into a strand, cooled and stretched and then tempered at a temperature in the range of 40 to 120 DEG C for 0.01 to 10 min. The invention further relates to the use of a monofilament produced by the method for the manufacture of artificial turf, wigs and bristles for brushes and paintbrushes.

Description

[0001] This application is a divisional application of the 200980150105.2 patent application for invention filed on October 13, 2009, entitled "Method for Preparing Monofilament and Application of the Monofilament". technical field [0002] The invention relates to a method for producing at least one monofilament from a thermoplastic polymer material. The invention also relates to the use of this monofilament. Background technique [0003] Monofilaments are used, for example, in the manufacture of artificial turf. Other uses include, for example, artificial hair for wigs and bristles for soft or hard brushes. [0004] Artificial turf is used, for example, in outdoor areas of hotel establishments or on sports fields. Depending on the kind of sports played on the sports field, the bending recovery and sliding properties of artificial turf fibers are particularly important. Currently, artificial turf fibers utilize polyolefins, which have good sliding properties but poor ben...
