1.Background to Development

(1) In 2002, NIKE proposed the "NIKE SPHERE REACT" concept to TFJ. This involved fabrics that undergo dynamic structural changes to adapt to the wearer's environment and to maintain a comfortable personal atmosphere.

(2) With a view to realizing this concept, after joint research got underway with the "NIKE Global Advanced Innovation Team", who is involved in the development of new products for NIKE from the fabric development stage, a fiber was successfully developed that featured self-regulating functions for adapting to environmental changes.

(3) The "M.R.T. Fiber", used to created this ground-breaking new fabrics, is a next-generation fiber the likes of which has never been seen before that has reversible transformation properties, whereby the fiber stretches when moisture is absorbed and shrinks when it dries out.

2.Technical points in the development of NIKE SPHERE REACT
(1) Fiber development
Newly developed was the "M.R.T. Fiber", a fiber capable of reversible transformation in that it stretches / shrinks when moisture is absorbed and shrinks when it dries out.

This fiber has enabled the realization and control of outstanding moisture absorption and stretch functionality through the fusion of the following new polymer technologies and new yarn-making technologies.

a. New polymer
We have developed a polyester ester polymer that absorbs and discharges moisture quickly.
