Synthetic hair fibers from PBT and PBT/PET blends via melt spinning

Overview

Suntech Engineered Materials presents a cutting-edge approach to producing synthetic hair fibers by leveraging the unique properties of Polybutylene Terephthalate (PBT) and Polyethylene Terephthalate (PET) blends. Through the process of melt spinning, this technology aims to create synthetic fibers that closely mimic the characteristics of natural hair. By combining PBT's elasticity and chemical resistance with PET's tensile strength and thermal stability, the resulting fibers offer superior performance, making them ideal for high-quality wigs and hair extensions. This innovation provides a compelling alternative to traditional modacrylic fibers, with enhanced strength and flexibility.
