Introducing
the “COOLBIZ
TECH ” Scheme.
“Power Saving Actions” are activities undertaken by individuals in anticipation of a substantial
summer power shortage. New ideas have been devised in the fields of food, clothing and shelter
to save power and spend summer comfortably.
The “COOLBIZ TECH” Scheme focuses on high-function textiles, especially in the fields of
“clothing” and “shelter”, and proposes power saving through the use of such textiles.
Support will be provided through the use of the fiber technology possessed by Japan as
one measure of the “Power Saving Actions.”

Sweat-absorbing,

A material that effectively absorbs sweat,
allowing the skin to feel comfortable by preventing
stickiness and providing a dry and smooth feel.
Another delightful feature is quick-drying after washing.
How it Exploiting the capillary phenomenon, the sweat-absorbing
Works?
material wicks away sweat. Increasing the surface area of
the fibers facilitates this process using the capillary phenomenon.
The surface area of fibers is increased by: (1) Making fibers
extremely thin so that multiple fibers can be combined, (2)
Changing the fiber shape to facilitate the suction of liquid, or
using other methods. The large surface area of the fibers allows
the suctioned sweat to be easily diffused and evaporated,
meaning both sweat-absorbing and quick-drying performances
can be provided simultaneously.

Cool Contact

A cool contact sensation material that quickly absorbs
heat is recommended for overheated bodies.
With a cool feel, it allows a feeling of pleasant comfort to be
maintained, even in sultry summer.
How it The material is pleasantly cool to the touch. Chemical
Works?
fibers such as rayon and cupro and natural fibers such as
hemp are originally known as materials that are cool to the touch.
The material contains a high level of moisture in its fibers, easily
conducts heat and feels slightly hard (soft and fresh) when
touched among other things. These features affect the cool
contact sensation. Recently, various cool contact sensation
materials have been commercialized, including one that imparts
hydrophilic properties to the surfaces of polyester fibers and
special chemical fibers that easily conduct heat.

state when they are dry. Temperature and humidity inside clothing
are automatically adjusted and comfort is maintained by skillfully
utilizing these fibers, e.g. opening stitches as fibers elongate (to
facilitate aeration) when humidity inside clothing rises due to
perspiration and by reverting to the original state (where aeration
is controlled) as stitches close up again when fibers dry out.

less outdoor heat indoors to enhance the cooling effect compared
with ordinary materials.
