Polyester bonded monocord sewing thread for use on single needle quilting machines. Made from high tenacity polyester Multifilament, Polymo Quilt is a monocord product designed to perform to the highest standards in the industry for todayâ??s quilting and mattress manufacturers. High-speed, multi-directional sewing creates thread rotation, causing traditional plied threads to untwist and fray. Thread Quiltâ??s unique, single-ply construction eliminates ply untwisting problems. A single ply of multi-filament nylon is lightly bonded at its point of contact, just enough to form a cohesive element without stiffening the product.
