Abstract
A 3-bar Raschel warp knit fabric for use in grasscatcher bags which has an additional high tenacity yarn knit in to provide a lower elongation yarn in the course direction to prevent the grasscatcher bag from dragging the ground as it is being filled. The fabric also has a second textured needle lap stitch yarn to provide cover and to prevent the exhaust of dust to the atmosphere from the interior of the bag.
