Bonded sewing thread typically a two, three, or four-ply construction coated with resin that makes filaments twisting more tough with a uniform finish which prevents the ply ends from unraveling in the reverse direction. Besides adding abrasion resistance and smooth stitching, the resin coating improves environmental resistance like heat tolerance, chemical and mildew resistance. Therefore, bonded thread outperforms non-bonded thread in most heavy fabric applications where bonded thread is always the superior choice.

Types of Heavy Duty Bonded Thread

Heavy Duty Nylon Bonded Thread

Heavy duty Nylon bonded thread is made from strong nylon 6 and nylon 6.6 continuous filament with resin coating that further protects thread from fraying, unraveling and breaking. The thread is suited for heavy fabric that requires certain stretch and more tensile strength.
