How it Works

Hollow yarn refers to a type of polyester fiber with a hollow structure, where the hollow degree of the fiber is ≥22%. This special structure allows a large amount of static air inside the fiber, enhancing the thermal performance of the finished product. Compared to conventional fibers, hollow fibers of the same thickness have a lower weight, reducing the fiber weight by 22%, which gives the finished product a lighter feel.

Ultra-Light

Compared with conventional fiber, hollow fiber of the same thickness has a lower weight, which can reduce the fiber weight by 22%, so hollow fiber can make the finished product have a lighter feel.

Ultra-Warm

Hollow degree of polyester fiber ≥22%, special hollow structure, so that a large amount of static air inside the fiber, thus conducive to the thermal performance of the finished product.
