Special Cross Section Fiber Octa®

Through a variety of fiber shapes, we can add the perceptual qualities of softness, draping, dry touch and the functionalities of sweat absorption, quick drying, non-see-through, lightweight, heat retention, and thermal insulation. Octa® is an exceptionally unique polyester fiber with a distinctive, highly modified cross-section with eight projections aligned in a radial pattern around a hollow fiber.

The voids in 8 fin fiber structure improve heat shielding and insulation properties, as well as create the lightweight feel of hollow yarn at roughly 50% weight of yarn of similar thickness.

Use & Function

The enlarged fabric structures

The octopus-like appearance, OCTA® fiber is targeted to fall and winter middle layer, lining materials for outerwear in fashion and outdoor industries. The spaces between the projections preserve body heat to give extra warmth. OCTA® unique fiber construction contributes to quick drying and airy texture as fabrics with 50% lighter weight than regular polyester material.
