Friction disc for a false-twist device, comprising an annular hub, on which it is possible to fix a circular race formed by a polyurethane (PU) layer and has a minimum wall thickness required for a secure interlocking fit, the hub having a circumferential support ring and a central hole, by which the friction disc is fixed on one of the shafts of the false-twist device. To ensure better dimensional and form stability over a long service life of the friction disc, the formed race fixed on the hub is ground according to a predefinable profile such that the flanks of the race have a predefinable width dimension following the grinding process, and/or in that the hub has, at a spacing from the support ring, a circumferential shoulder for abutment for the fixable PU layer, a cross-sectional width of the shoulder being smaller than a cross-sectional width of the support ring.

A method includes drawing each of multiple partially oriented yarns from a corresponding supply package to form an oriented yarn, twisting and detwisting filaments within the oriented yarn to provide texture thereto, to provide a low stability interlacing during weaving, and to intermingle the filaments comprising the oriented yarn, and applying a uniform air pressure to the oriented yarn to provide a counter-twist. The method also includes forming a multi-pick yarn package based on winding all formed oriented yarns, which serve as weft yarns forming adjacent substantially parallel yarns wound together, onto a spool, simultaneously inserting the weft yarns in a single pick insertion event of a loom apparatus, conveying the weft yarns across a warp shed of the loom apparatus through a set of warp yarns, and interlacing the set of warp yarns and the conveyed weft yarns to produce an incremental length of a woven textile fabric.

The method of manufacturing a textured artificial turf yarn includes providing a monofilament yarn, wherein the monofilament yarn includes a polymer blend of polymers; receiving differential scanning calorimetry, DSC, data of a sample of the polymer blend; determining one or more melting temperatures of the monofilament yarn using the DSC data; and texturing the monofilament yarn within a chosen temperature range using a texturing device to provide a textured artificial turf yarn, wherein the chosen temperature range is selected using the one or more melting temperatures.
