Japan develops sunlight, human far-infrared heating fiber

In Japan's autumn/winter 2010 lingerie market, the warfare of heat and heat preservation functions has become increasingly intense. Due to the fever of the speciality store retailer of private label Apparel and the warming of underwear in the last year, competitive underwear manufacturers have successively invested in the production of goods, as well as clothing chain stores and self-owned brands of large-scale integrated shopping malls (GMS). (PB commodities) will also be heavily invested, and companies in other industries, such as garment manufacturers, will also join this market.

Speaking of fever, heat-retaining functional fibers, the majority of moisture-absorbing and heat-generating types that absorb moisture from perspiration and circulate to generate heat and dehumidify. Omikenshi, a representative manufacturer of functional textiles in Japan, started to develop functional fibers that can produce heat and heat without water, and thus created Solar Touch.

"Solar Touch" is a staple fiber that incorporates a particulate metal oxide. The particulate metal oxide absorbs the infrared rays emitted by the sun and the human body and becomes self-heating due to heat. From the sun there are all kinds of light shining on the earth. This light is also called “electromagnetic wave”, which means fluctuating energy but not heat. Substances absorb volatile energy and resonate, and molecular movements become lively. In the matter, molecules make collisions with each other and produce heat energy to increase the temperature of matter. "Solar Touch" is a functional fiber that utilizes this principle.

"Solar Touch" makes the fibers warm by incorporating rayon metal oxides that absorb infrared rays in a wide range. Unlike hygroscopic heat-generating fibers, even if it is in a dry state, it can heat, so it does not need to sweat.

In the company's test, "Solar Touch" heat is even higher than cotton. "Solar Touch" uses a 30% cotton blended knitted fabric, so the heat is high, so the insulation continues longer. In addition, there is the "Solar Touch" special function that can use the far-infrared light emitted by the human body to generate heat and heat.

"Solar Touch" is also developed as an environmentally friendly product that prevents the global warming. Energy saving in homes and offices, even if the heating is down 1 to 2 degrees Celsius, it will not feel cold and it will contribute to reducing carbon dioxide emissions.
