Core Viewpoint - The innovative basalt fiber fabric developed by Wuhan Textile University demonstrates exceptional fire resistance, capable of withstanding temperatures above 1200℃ without damage, making it suitable for various protective applications [1][10][19]. Group 1: Material Properties - The basalt fiber fabric can be used in extreme temperature environments ranging from -260℃ to 700℃ and can resist short-term high temperatures exceeding 1000℃ [1]. - Traditional fire-resistant materials, such as aramid, fail under similar conditions, while the new basalt fiber fabric remains intact after exposure to 1200℃ flames for 10 seconds [10][14]. - The fabric is made from basalt fibers, which are natural fire-resistant materials that also exhibit resistance to acid, alkali, and radiation [13]. Group 2: Technological Advancements - The "core-spinning" technology developed by the research team allows for the wrapping of soft yarn around the brittle basalt fibers, enhancing comfort and usability while maintaining protective qualities [6][19]. - The diameter of the basalt fibers has been reduced to just 5 micrometers, with lengths reaching up to 100,000 meters, facilitating easier processing and application [19]. Group 3: Applications and Market Potential - The basalt fiber fabric is already being utilized in the production of fire-resistant clothing, bags, ropes, and blankets, with successful trials conducted in various provincial fire departments [18][19]. - Collaborations with sports brands like Anta are underway to develop consumer products made from basalt fiber, indicating a potential expansion into the retail market [18]. - Future applications may include the development of aerospace suits and construction materials for lunar exploration, leveraging the similarities between lunar regolith and basalt structures [18].
