HEATTECH’s role in reducing the effects on theenvironment

Effects on saving energy and reducing CO2
The superior heat retention function ofHEATTECH allows us to comfortably lower theroom heater temperature by 1 degrees Celsius.
We calculate the effect of this on saving of energy
and reducing CO2.
11

[Effects of 100 million units of HEATTECH][Energy Conservation]
58W/household × 12.5million households = 730,000kw
100million units divided by 〔8 units/household〕 = 12.5 million households
The amount of energy conserved by lowering the heater temperature by 1℃ is
58w/household[CO2 Reduction]
13kg-co2eq/HEATTECH item & season × 100million units= 1.3million tons
Reduce CO2 emission by lowering the room heater temperature
The amount of CO2 reduced by every piece of HEATTECH is equivalent to theamount of CO2 absorbed by a cedar tree

It is equivalent to a forest area of approximately
1,093km2, or half the area of Tokyo.

[Advanced Nylon Dyeing Technology]
Integration of advanced Japanese textile technologies
with skilled craftsmanshipWe succeeded in dyeing nylon evenly, using the dyeing
expertise that we have accumulated thus far and using a special
dyeing machine15

[Light & Warm of Ultra Light Down]
The use of an ultra fine nylon thread with similar thickness to a human hairmakes it soft and light!
