A clothes iron is a small appliance used to remove wrinkles from fabric. It typically has a flat, heated plate that is pressed against clothing to smooth out creases. Most irons have adjustable temperature settings to accommodate different types of fabric, such as cotton, polyester, and silk. Many irons also feature a steam function, which releases moisture to help relax fibers and make ironing easier. Some models come with additional features like automatic shut-off for safety and non-stick surfaces to prevent fabric from sticking. Irons are commonly used in households and by professionals in the clothing industry.
