Traditional polyester fibers have been criticized for their poor breathability, but through improved spinning processes (such as honeycomb structure design), the moisture wicking ability of the new generation of polyester fabrics has been significantly improved. In addition, the application proportion of recycled polyester (rPET) in sports bras has reached 40%, reducing dependence on petroleum-based raw materials.
Polyester technology has undergone upgrading, with an increased proportion of recycled materials.
