Product Details
MH High Tenacity Polyester Sewing Thread is a 100% polyester filament thread supplied in 100D, 150D, 210D, 250D and 420D deniers for stitching leather and other heavy materials.
The thread is spun from continuous high-tenacity polyester filament and bonded, then finished to a gentle luster and a smooth surface so it feeds cleanly through high-speed and multi-needle industrial machines.
Typical applications include leather footwear, leather goods, suitcases, automotive interiors, seat belts, airbags, outdoor and sports equipment, multi-needle quilting, mattresses and filtration fabrics. MH produces the thread to custom colour, denier and cone size, working either from an extensive standard shade range or from a buyer's own colour reference.
Key Selling Points
Seam strength for hides and heavy panels: MH High Tenacity Polyester Sewing Thread is engineered so seams in leather, webbing and coated fabric keep their hold under sustained pulling load.
Smooth, gentle-luster finish: The bonded, smoothly finished surface lets this polyester thread run at high machine speed with clean stitch formation and a tidy seam appearance on visible leather work.
Chemical and abrasion resistance: High chemical resistance and heavy-duty abrasion resistance keep the thread intact where needle friction, cleaning agents and outdoor exposure would degrade weaker sewing threads.
Colour matching to your leather: An extensive dyed shade range plus lab-matched custom colours let footwear and leather goods factories align stitch tone with each hide or trim.
Custom denier and cone build: MH manufactures this leather sewing thread to a specified denier and cone size, so the same quality can be set up for shoe uppers, sole stitching or upholstery lines.
Supply built for repeat production: As a thread manufacturer serving footwear, leather goods, upholstery and automotive suppliers, MH holds consistent quality across repeat bulk orders.
