Bonded nylon sewing thread is made from continuous filament high tenacity polyamide 6. It is manufactured using a co-polymer based bond. This unique bond prevents filamentation and ply separation during the sewing process, thus delivering exceptionally strong and durable seams. It has two kinds: inner bonded nylon thread and outer bonded nylon thread, and both of them are lubricated, which ensure smooth, trouble-free sewing. It's widely used in leather goods, canvas work and sports footwear.
