The Four main Features of Teviron Technology

01.

Superior Heat Insulation

The Journal of Occupational Health (Japan) conducted a comparison of different materials of the same thickness to determine heat insulation capability. In comparing the difference in temperature between covered and uncovered areas of skin, the differences were plotted in the graph below, material types plotted on the Y-axis and temperature difference plotted on the X-axis. At 77 F, the different materials showed little temperature difference, but at 41 F, there was an obvious difference in heat insulation, with the Teviron material showing its superiority in retaining heat even at low temperatures.
The two figures below are derived from a report by Teijin Limited Company of Japan. The long sleeve undershirts in the images are made of wool on the right side, Teviron on the left. A heat sensor was used to register the temperatures and the results were displayed on a computer (higher heat dispersion is represented by warmer colors).

Excellent Moisture Permeability

Heat insulation can be either stiflingly hot, which keeps sweat inside the material and is uncomfortable, or it can be dry and warm. Since Teviron does not absorb water and has superior sweat dispersion features, it is not only warm but also dry. (Right)

The diagram below is taken from a study by the Carl Marx Textile Research Institute of Germany. Since Teviron has great heat insulation and does not absorb water, many people might think that Teviron is not a breathable material and therefore would be uncomfortable to wear. However, as you can see from the chart below, Teviron allows very rapid water dispersion and therefore keeps the person inside dry and warm. We call this "sweat dispersion technology," and the only material that can reach this level of sweat dispersion is Teviron.
The diagram below is taken from a report by Teijin Limited Company of Japan. Specially designed clothing (one side made of cotton, the other Teviron) was worn by a subject while exercising and sweating. The cotton side took approximately 40 minutes to dry, while the Teviron side only needed 10 minutes to become completely dry.

Water/Absorption Rate(%)

Material	Teviron	Polyester	Acrylicfiber	Cotton	Wool
Water Absorption Rate	0	0.4~0.5	1.2~2.0	8.5	15.0

Safety/Fire Retardance

Japan Fire Retardant Association (JFRA)
Teviron ensures every individual's safety, with its inherently fire retardant quality.

Material	Teviron	Acrylicfiber	Wool	Polypropy lene	Nylon	Cotton
LOI Value	35-37	26-28	24-25	20-22	20-22	19-21

* Under normal condition, LOI value smaller than 24 is highly flammable while those higher than 24 is
lessflammable.

Amazing Negative Ion Technology

When two fabrics rub against each other, one side generates positive static electricity while the other generates negative static electricity.
When rubbing against all fabrics or skin, Teviron can generate negative static electricity. The unique negative ion effect generated by Teviron is good fo health.

Diagram 1
The diagram below indicates the results measured by an electric ions detector. This experiment was carried out by rubbing Teviron against wool.
The indicator pointing towards the left shows that negative electric ions were present in Teviron and positive electric ions were detected in wool, as shown by the indicator pointing towards the right.

Diagram 2
The diagram below right is a static comparison chart for various fabrics compiled by the Textile Research Institute of Japan. This proves clearly that Teviron can generate negative electric ions when rubbing against all fabrics.
