The number of needles in artificial turf refers to the number of clusters of grass and silk per square meter of artificial turf. The number of lawn needles commonly used in football fields is 10,500 stitches, which means that there are 10,500 tufts of grass per square meter.
So how do we quickly calculate the number of clusters per square meter? If the pitch of the lawn model is 3/4, then there are 52.5 rows of grass per meter wide, and the number of clusters per meter in the longitudinal direction is 10500/52.5=200 clusters, then the number of clusters per 10cm is 20 clusters. . That is to say, in the lawn with a pitch of 3/4, the number of clusters of 10 cm in the longitudinal direction of each row is 20 clusters, which is equivalent to 10,500 needles per square meter.
The same method can be used to calculate a standard pitch of 5/8, with a lawn of 10,500 needles per square meter, and the number of clusters per 10 cm is 16.7 needles.
