Flame-resistant fabrics are specially designed materials that resist ignition and prevent the spread of flames. These fabrics are often used in protective clothing for workers in hazardous environments, such as firefighters and industrial workers. The treatment process can involve chemical coatings or the use of inherently flame-resistant fibers. Common types of flame-resistant fabrics include Nomex, Kevlar, and Proban. These materials are tested to meet specific safety standards, ensuring they provide adequate protection against heat and flames. Proper care and maintenance are essential to maintain their effectiveness over time.
