What is Tsunooga® ?

Tsunooga® is high molecular weight
polyethylene yarn produced by TOYOBO in Japan.
Fabric made with Tsunooga® provide a great cooling
sensation.

※q-max is the value which shows cooling performance.
Cooler fabric has higher q-max value.

Cooling recovers quickly

Tsunooga® fabric has very high thermal diffusivity,
therefore, cooling recovers quickly every time you turn over in bed.

Tsunooga® is a multiple filament yarn which is a bundle of very fine filaments.
By reducing the diameter of the filament to only 12 μm,(almost 1/5 of human hair) the surface area of the yarn is increased,
and the thermal diffusivity and heat dissipation are also increased.
As a result, cooling recovers very quicky.

Cooling is lasting after washing

Tsunooga® fabric is machine washable at home.
Cooling property comes from fiber characteristics,
therefore, washing durability is clearly different from post-processed fabric.

-High thermal diffusivity fiber-
Yarn itself has cooling characteristic,
Almost no difference after washes.

-Cooling material will drop by washing-
Post-processed cooling fabric (ex. Xylitol)
will reduce its function after several washes.
  • ※If fabric get a fluff after repeated washes, it may cause of cooling degradation.
  • ※Tsunooga® is heat sensitive material, so we do not recommend you to use tumble dryer or iron.

Application

  • Pillow cover

  • Bed pad, Topper
