Bonded Nylon is the popular choice to use when stitching upholstery, leather and other heavy fabric.
Coated by the bonding agent, it won't unravel and it adds strength and reducing friction at the needle resulting in smooth stitches.
Selric 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.
