Straight yarn play an important role in the composition of artificial grass and is widely used in sports grass and landscape grass. It is normally made from polyethylene(PE) which is soft, durable and UV stable.
The fibers are extruded through a spinneret. The die hole of the spinneret determines the cross section of the blades. The cross section can be designed in the shapes of rectangle, C, D, M, S, U,V,W, diamond and stem which have different performance characteristics. The yarn blades are extruded individually and then winded together in clusters. Usually there are 6 or 8 individual filaments per cluster.
