Heat-resistant fabrics are specially designed materials that can withstand high temperatures without melting or degrading. These fabrics are often used in protective clothing for workers in industries like welding, firefighting, and cooking. Common examples include Nomex and Kevlar, which provide safety and durability in extreme conditions. These fabrics are made from synthetic fibers that have been treated to resist heat and flames. They are essential for ensuring the safety of individuals who work in hazardous environments, as they help prevent burns and other heat-related injuries. Additionally, heat-resistant fabrics are also used in various applications, such as insulation and fireproof curtains.
