2012—New Proposal for
Functional Innerwear – Silky Dry
Mr. Genichi Ishikawa
ManagerToray Industries Inc.

Silky Dry: Ultra comfortable
Innerwear for Men•

Silky Dry was developed to offer men more comfortable underwear.

•Improved perspiration and odor. The fabric absorbs perspiration,dries quickly and has anti-microbial and anti-odor functions.

•Made with micro fibers jointly developed by Toray and UNIQLO thatincorporate extremely fine cationic-dyeable polymers.

•The ultrafine fibers deliver an amazingly smooth feel and a fit that isUltra Comfortable. The fit is so light that it gives wearers the sensation
they are not wearing innerwear at all.

Improvements for Silky Dry in 2012

• Lighter• Thinner• Cooler• Smoother• Improved Dry Performance
Taking the “wearing nothing” concept to the nextlevel3

Silky Dry
Improvement begins with single filaments
Finer: About 20% finer; approximately 1/12 the thickness of human hair

KES surface roughness measurement device
The smoothness of thesurface is measured byrunning a needle along
the material and gauging
the degree of theneedle's verticalmovement. The smaller
the needle's verticalmovement smoother thesurface.

6Silky Dry
Improved Dry function!
The secret is ultra fine fiber
Numerous very small spaces were created between the individual fibers. The increased
number of spaces promotes capillary action, which enables quick absorption of moisture. As
a result, the material effectively absorbs moisture and quickly dissipates it. The area incontact with the air has been increased to make it easier for moisture to evaporate. The feel
is silky and comfortable because the material dries quickly.
