Bonded Nylon is the popular choice to use when stitching upholstery, leather, automotive interiors, heavy fabrics and more. Superior's Bonded Nylon is Nylon 6,6 (sometimes referred to as Nylon 66).  Nylon 6,6 is stronger and has a higher heat tolerance than regular Nylon.  The bonding agent which coats the Nylon 6,6 fibers give this thread added strength and reduces friction at the needle resulting in smooth stitches.  Our bonded nylon is a final Z twist.
