"Non-Iron" refers to fabrics that are treated to resist wrinkles and require little to no ironing after washing. This treatment helps maintain a smooth appearance, making these garments convenient for everyday wear. Common materials include cotton blends and synthetic fibers, which are designed to retain their shape and look fresh. Many clothing brands offer non-iron shirts and pants, appealing to busy individuals who prefer low-maintenance options. The technology behind non-iron fabrics often involves chemical treatments that alter the fibers, ensuring they remain crisp and wrinkle-free throughout the day, even after multiple washes.
