Abstract

A fibre for use in artificial turf has an elongate cross-sectional shape defining a first face and a second face that meet at side edges of the fibre. The first and second faces having respective first and second ridges that are offset with respect to each other, such that the cross-sectional shape is 2-fold rotationally symmetric with no reflectional symmetry. The fibre may be an extruded monofilament and shows improved resilience over symmetrical fibres of similar dimensions.
