What fabrics are microwaveable?

Microwaveable fabrics typically include cotton, polyester, and certain blends specifically labeled as microwave-safe. It's essential to avoid fabrics with metallic threads or coatings, as these can cause sparks or fires. Additionally, some specialized fabrics designed for food heating, like those used in microwaveable bowls or bags, are made to withstand the heat without melting or igniting. Always check the manufacturer's guidelines to ensure safety.
