Bonded Nylon 6,6 thread. Designed for heavy-duty sewing applications.
Bonded Nylon is the popular choice to use when stitching upholstery, leather, vinyl, and other heavy fabric. Superior's Bonded Nylon is Nylon 6,6 (sometimes referred to as Nylon 66) which is stronger and has a higher heat tolerance than regular Nylon threads. 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.
