Teijin Limited, a global technology solutions provider group, has recently developed an extra-soft polyester hook-and-loop fastener – FASTENANO™, which will make it to the global market soon.
FASTENANO uses Teijin’s NANOFRONT® polyester nanofiber-pile fabric, the world’s first 700-nanometre ultra-fine polyester fibre, 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, courtesy to NANOFRONT® pile fabric’s high friction property, which twines 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.

It may be mentioned here that NANOFRONT® features nano-sized bumps that increase its surface area by dozens of times compared to regular fibre, resulting in excellent slip resistance, softness, heat shielding, absorption, translucence and filtering properties. Teijin is now developing FASTENANO items that will do away with pesky hooks and buttons, including bedclothes, sundries, furniture, apparels, uniforms and medical applications.
