Artificial fibre as well as an artificial lawn for sports fields provided with such fibre

Abstract

The invention relates to a method for producing a foil of synthetic material composed of a first synthetic compound and a second synthetic compound, in which the first synthetic compound consists of a polymer and the second synthetic compound consists of a plastomer. The invention also relates to a synthetic fibre and to an artificial lawn suitable for sports fields, consisting of a substrate to which synthetic fibres according to the invention are fixed. Surprisingly, it has become apparent that when the fibres are according to the invention made from a combination of synthetic materials in which the first synthetic compound is a polymer and the second synthetic compound is a plastomer, the fibres will only exhibit a very minor any tendency to split, or even no such tendency at all, not even after stretching, also in the case of very intensive use in an artificial lawn. This renders the fibre very suitable for use in an artificial grass sports field, so that the field will not only require less maintenance but, in addition, will be capable of withstanding longer and more intensive use. Since the synthetic fibre—in addition to an improved splitting behaviour—exhibits strongly improved elastic and springing properties, the risk of injury and/or burns caused by slidings or falls is significantly reduced.
