Product Introduction
TPU Thermoplastic Polyurethane Upper Yarn is a type of yarn made from thermoplastic polyurethane (TPU)-a flexible, durable material that melts with heat and bonds when cooled. It's designed specifically for upper materials in footwear, especially in sports shoes and sneakers.
If you've seen those modern, seamless sneaker uppers that look clean and feel stretchy, that's where this yarn comes in.
Why TPU?
TPU is known for its flexibility, toughness, and resistance to oil, sweat, and abrasion.
Compared to traditional yarns like polyester or nylon, TPU brings in extra elasticity and durability. And if you're using TPU hot melt yarn, it melts and bonds cleanly when heated-no glue required.
