As one of the most typical functional fibers, heat-storage fibers can have an appropriate amount of nano cesium tungsten oxide powder added during production as a modifier to further enhance their heat-storage capabilities.
Fibers are materials composed of continuous or discontinuous filaments. Based on their sources, they are classified into three categories: plant fibers, animal fibers, and mineral fibers. Plant fibers are obtained from seeds, fruits, stems, or leaves of plants, such as flax, jute, ramie, sisal, and banana fiber. Animal fibers are derived from animal hair or insect gland secretions, including wool, rabbit hair, camel hair, goat hair, and yak down. Mineral fibers are extracted from fibrous-structured mineral rocks, primarily composed of oxides like silicon dioxide, aluminum oxide, and magnesium oxide, with major sources being various types of asbestos, such as chrysotile and crocidolite.
Whether plant, animal, or mineral fibers, they can be used to produce items like ropes, felt, clothing, and quilts. However, since clothing made from pure fibers offers poor thermal insulation, manufacturers now incorporate small amounts of functional materials, such as nano cesium tungsten oxide powder, during production.
Nano cesium tungsten oxide powder, a compound of the inorganic metal tungsten, is characterized by being non-toxic, environmentally friendly, non-radioactive, and possessing strong near-infrared absorption capabilities. These properties enable it to impart enhanced heat-storage functions to ordinary fibers. Specifically, fibers containing cesium tungsten oxide powder can convert sunlight or infrared rays into heat energy and store it within the fibers, addressing the issues of traditional clothing being heavy and lacking warmth.
