A 'side by side' hollow fiber made of PTT and PET

Made of PTT (Polytrimethylene Terephthalate, DuPont Sorona) with a molecular structure differentiated from the existing polyester and nylon and developed based on Huvis' proprietary special spinning technology, Polarfil provides soft touch, high bulkiness and excellent resilience differentiated from existing fiber. As an alternative to down, Polarfil can be used as ball fibers and non-woven fabrics for padding.
