When tufting the artificial grass, the sewing needle can go along a straight line, or go z-way needling (some people also call z-stitch ). The featured image shows how W-stitching artificial grass looks like.
As most of the artificial grass products on the market still use the normal straight needling, Z-way needling makes the product more or less stand out of the ordinary.
Some people say W-stitch or Z-stitch makes the artificial grass backing hold the yarns tighter, according to our experience, both the straight needling and W-stitch needling works similarly. With high-quality coating, both the two kinds of artificial grasses are very durable.
