1. Q: Is this Heating Dty yarn washable or durable?

A: Yes,Far-infrared composite powder is embedded in the fibers. It’s not easy to peel off and more washable. It has been tested by the authority:With Japanese standard sope 20 times,equivalent to the national standard 100 times simple washing,silver irons content only decreases by only 13% from 30ppm down to 26ppm.

2. Q: Do you know the five types of heating fibers?

A: Traditional winter clothing such as cotton wool, down, fur and various kinds of chemical fiber floss and other warm materials clothing, mostly by preventing the heat to achieve the effect of warmth, its disadvantage is thick and bloated. With the improvement of people's aesthetic and comfort requirements, light and thin fabrics that can heat and keep heat are increasingly favored, thus promoting the research and development of heating fibers.Thermal fiber is a new type of fiber that generates heat and keeps warm by itself. It can not only prevent heat dissipation like traditional fibers, but also absorb, store and transfer external heat to the body. In terms of the heating mechanism, the heating fiber mainly has several types, such as light energy heating, electric energy heating, phase transition exothermic heat, chemical exothermic heat and hygroscopic heating.

Light heating fiber:Absorb far infrared light and generate heat (far infrared fiber).It is generally made by evenly adding far infrared absorbers (ceramic powder) to polyester, polypropylene and other fibers. Ceramic powders are mostly metal oxides, such as alumina, magnesium oxide, zirconia, and sometimes titanium dioxide and silicon dioxide. For example, Ceramino fiber, a thermal storage and insulation polyester material developed by Japan Bell Spinning synthetic fiber Company, evenly penetrates far infrared absorbers into the internal structure (amorphous area) of the fiber molecules during the post-processing process, which improves the absorption of external infrared rays such as sunlight and plays a role in heat storage and insulation.Japanese company Komatsu Refining created DynaLive by adding infrared absorbant and glass beads to a polymer. The inner temperature of the garment made of this fiber is 3~7℃ higher than that of the ordinary fabric. Others include Fujifilm's INSERARED fiber and Clari's LONWAVE fiber.

Absorb visible light and near infrared heat:Japan Unijica's Thermotron fiber core is coated with tiny particles of zirconium carbide, which emits heat under the action of solar heat and reflects long wavelength far infrared, making the inside of clothing warm. Mitsubishi Rayon's colorless photothermal conversion polyacrylonitrile fiber Thermocatch core contains fine semiconductor particles (tin oxide and antimony oxide complex micropowder) that absorb near infrared rays and convert light energy into heat energy. When exposed to light, blended yarns with more than 10% Thermocatch fiber content can convert light energy into heat energy and raise the temperature by 2 to 10℃. In addition, Toray's "Torayheat" fiber not only absorbs visible light and converts it into heat, but also has anti-static and anti-pilling effects.

Electric heating fibre:Electric energy heating fiber is a composite fiber containing electric heating material components, its principle is to heat through the conductive fiber, to achieve the thermal effect. At present, the widely used conductive fiber is carbon fiber. In addition to rapid heating and high conversion rate of electric heating, carbon fiber also has the function of generating far infrared ray when heating. Therefore, using carbon fiber heating material can develop heating and warm clothing with health care function. In 2004, WarmX, a German company, developed a line of underwear made of very fine silver fibers and a small rechargeable battery that can be used to power the body. The underwear can keep warm even when the temperature is very low.
