Definitions
- the invention relates to a method for producing yarn for fields of artificial grass by extruding polymer granulate to bands or to a film, cutting the film to bands and stretching the bands.
- the invention also relates to the grass fields produced with this yarn.
- This process according to the invention as disclosed in the preamble is characterized by the fact that bands having a thickness of 100 ⁇ m and a width of 1.5-4 mm are stretched at a stretching ratio of 1:2-3, to bands having a width of 0.75-3 mm and the extruded band has a thickness of 50-80% of the original thickness, and then 5-10 bands are twisted to yarn.
- the bands Preferably have after extrusion a width of 2-3 mm and after stetching, during which the thickness of the band is 50-70% of the original thickness, a width of 1-2 mm.
- the bands have a yarn number of 900-1350 dtex and that beside polypropylene a blockcopolymer is used as sold by Solvay, Belgium.
- the cutting of the bands from the film and the stretching can be reversed, so that it is possible to stretch bands as well as to stretch the film.
- An extruder is fed with propylene having a melting index of 2. From this a film is produced having a width of 750 mm and a thickness of 100 ⁇ m. Said film is cut into bands being 2-3 mm width, while the thickness is maintained. Stretching takes place at a temperature of about 130 °C at a stretching ratio of 1:2.5. It also is possible to stretch at first the film and to cut bands from the stretched film. A hot-blast furnace is used for the stretching operation. After relaxation, cooling and shrinking, bands are obtained, having a width of 1.5 mm and a thickness of 60 ⁇ m. Eight of these bands are twisted in a yarn which can be processed into a carpet for a field of artificial grass by means of a tufting operation.
