Made from 100% nylon yarns, this natural white twine is resistant to abrasion, oil, gasoline, decay, marine environments, and most chemicals. The formulas we use to twist this twine have been developed to give just the right amount of "Z" and "S" twist. This mechanically sets the twine.Most companies would be satisfied with a twine of this quality, but we take it to a higher level by stabilizing it with a special heat treatment. This heat treatment insures the highest level of twist consistency, with minimum amount of raveling, untwisting, and kinking. Uses for this twine include trot line, decoy line, net making and mending, workshop, crafts, gardening, construction, and commercial applications.Any place a high quality twisted nylon is needed this "Type AA" twine will fit the bill. We are not responsible for injury or property damage in the use of any product that we sell. Rope tensile strength (the lb test rating) is for new rope under laboratory conditions. Safe working strength is generally 10% to 15% of the given tensile strength.
