Toray announced that they had developed a new material making full use of nanotechnology, "Nano-Plem" for various applications and "DEEPLEM NT" for deep-black school uniforms.

Toray gave an explanation at the press conference about the development of "Nano-Plem" which will form the basis of new textile finishing technology with nanotechnology. "Nano-Plem," nano-scale finishing technology which can add new functions to fabric effectively, was developed by reforming the fabric surface and the inside at nano level after activating various synthetic fabrics such as polyester and nylon on the molecular level by applying high energy. This technology has made it possible to add entirely new functions to various synthetic fabrics and T/W blends, to balance several functions, to improve conventional functions and durability dramatically and to expand the range of applicable materials.

It became possible to carry out reformulation at nano level such as the introduction of functional groups, etching, cross-linking and graft because of "Nano-Plem" activating fiber-forming polymer on the molecular level by applying high energy such as ultraviolet rays, microwaves, electron rays, ions, electrons and radicals to fibers. It is possible to the reform fabric surface while maintaining the original characteristics of the fiber by adjusting the level of high energy applied, as well as reforming the inside of the fabric.
