FLEX FUSION is a fiber made of polybutylene terephthalate (PBT)
and conjugate yarn (commingled with PET).

The fiber realizes stretchability by compounding two polymers, PBT and PET.
Fully exploiting the advantages of a compound fiber,
such as easy-care quality and excellent durability against postprocessing
and factory washing, the fabric offers a wide variety of uses ranging from shirts and pants to sportswear.
