Patent attributes
An improved lacrosse mesh is made of polypropylene. Polypropylene fibers are among the lightest weight of all commercially produced plastic fibers. Typical polypropylene has a density of 0.9 g/cm3, much lower than that of polyester (1.38), cotton (1.54), or nylon (1.15). Additionally, polypropylene is known to outperform other dyeable fibers in low moisture absorption tests. Preferably a polypropylene-based material known as INNEGRA S is employed. It has a tenacity greater than 5 grams/denier, elongation prior to breakage of about 11%, density of 0.84 g/cm3, 93% of unprocessed polypropylene and a surface texture bearing striations that enhance its grippability to a degree desirable for use in netting for lacrosse mesh. The INNEGRA S material is much more difficult to stretch to any degree as compared to the more easily stretchable NYLON material and, as such, ideally maintains pocket shape in a wide variety of conditions.
