Temperature graphics of moisture-absorbing heat-generating fibers

Isn't UNIQLO's HEATTECH a famous moisture-wicking and heat-generating fabric sold all over the world?

HEATTECH is a registered trademark produced by Toray to produce moisture-absorbing, heat-generating fibers and sold by Uniqlo.

The idea behind Mizuno's moisture-wicking and heat-generating material ``Breath Thermo'' is a desiccant that removes moisture from inside shoes.

Its origin comes from the fact that when water is applied to the desiccant, the fibers become hot.

``Breath Thermo yarn'' is a yarn that does not stretch, so we devised a way to knit it to make the fabric stretch.

We have established a method that achieves both color development and texture of the fabric.

``Breath Thermo’’ has greater moisture absorption and heat generation performance than other acrylate moisture absorption and heat generation materials.

The fabric absorbs moisture → generates heat → retains heat, and wicks away excess moisture.

``Solisto Thermo'' is a fabric that combines microacrylic and rectangular cross-section rayon.

Always comfortable by controlling the temperature inside your clothes.

The effect of capillary action dries quickly and leaves your skin feeling refreshed.

Micro acrylic has a soft powder touch that is gentle on the skin.

Maintains volume and excellent heat retention.
