Product Details
420D/3 Nylon Bonded Sewing Thread
Nylon bonded sewing thread is made of polyamide synthetic fiber, processed through a special bonding technique that locks the filaments together while twisting, then finalizes the fiber bundle into a unified, non-separating thread. During high-speed sewing, the bonded thread resists fraying, prevents lint buildup, and delivers exceptional abrasion resistance for demanding industrial applications.
The 420D/3 construction provides extra heavy-duty tensile strength with reliable stitch consistency across the toughest materials. With an average breaking strength of ≥ 9.0 kg, this thread handles the most demanding sewing operations including safety harnesses, automotive interiors, marine upholstery, and heavy industrial textiles. The advanced lubricant treatment ensures smooth feeding and even tension, producing clean, professional seams on thick leather, coated fabrics, and multi-layer assemblies.
