Teijin’s FASTENANOTM Polyester Hook-and-loop Fastener Offers Extra-soft Touch

FASTENANOTM, an extra-soft polyester hook-and-loop fastener developed and marketed in Japan by Teijin Limited, will now enter the global market.

FASTENANOTM uses Teijin’s NANOFRONT® polyester nanofiber-pile fabric for its loop surface, as well as polyester raised fabric for its hook surface. While FASTENANOTM achieves high adhesiveness when pulled in a horizontal direction, it separates easily when pulled in a vertical direction. The key is the NANOFRONT® pile fabric’s high friction, which enables to twine effectively around the hook surface.

When the surfaces are separated, the ripping sound is much quieter than conventional hook-and-loop fasteners. The hook and loop surfaces both are very soft so they have a nice feel. In addition, their pliability enables them to be fashioned into various shapes.

NANOFRONT®, the world’s first 700-nanometer ultra-fine polyester fiber used for FASTENANOTM, features nano-sized bumps that increase its surface area by dozens of times compared to regular fiber, resulting in excellent slip resistance, softness, heat shielding, absorption, translucence and filtering properties.

Teijin is now developing FASTENANOTM items that will do away with bothersome hooks and buttons, including bedclothes, sundries, furniture, apparels, uniforms and medical applications. FASTENANOTM fasteners will go on sale in FY 2016.
