New Thermal Insulation and Temperature Regulating Textile Additive - Zirconium Carbide
Zirconium carbide has the characteristics of efficiently absorbing visible light and reflecting infrared rays. When it absorbs short-wavelength energy below 2μm, which accounts for 95% of sunlight, the energy can be stored in the material through thermal conversion. At the same time, it also has the ability to reflect infrared rays exceeding 2μm wavelengths. The wavelength of infrared rays generated by the human body is about 10 μm. When people wear ZrC-containing textile clothing, the infrared rays of the human body will not be easily emitted to the outside. Different zirconium carbide content and addition methods have a great impact on the near-infrared absorption properties of fibers. When the content of zirconium carbide reaches 2/10,000 (weight), the near-infrared absorption performance of the fiber is the best, and the near-infrared absorption effect of adding zirconium carbide in the fiber sheath is better than that in the core layer. This shows that zirconium carbide has ideal heat absorption and heat storage properties, and the product can be used in the field of new thermal insulation and temperature regulation textiles.
