Flat Multi-leaf Cross-section Polyester Fiber
PENTAS™α is flat, multi-leaf cross-section polyester fiber featuring tiny bumps across the flat cross-section. The bumps on the surface creates small spaces between fabrics when made into cloth or non-woven fabric, providing good water absorption and diffusion via the capillary effect. The multi-leaf cross-section lets the additive drugs used in later processes (such as water resistance) penetrate into the holes between the bumps, boosting functionality and resistance. The surface bumps also deflect and scatter light, providing potential extra opacity and reduced UV exposure. In addition, the flat-textured surface provides for smooth flexing and a soft feel on the skin.
