Yes, ceramic fiber fabrics can be used for clothing insulation. These fabrics are known for their high temperature resistance and thermal insulation properties, making them suitable for applications requiring protection from heat. They are often used in fire-resistant clothing and other protective garments. However, it's important to note that while they provide excellent thermal insulation, ceramic fiber fabrics may not offer the same level of comfort as traditional insulating materials due to their rigidity and potential for skin irritation.
