Wrinkle resistance refers to a fabric's ability to resist creasing and maintain a smooth appearance after washing or wearing. This property is often achieved through special treatments or the use of synthetic fibers, such as polyester or nylon, which are less prone to wrinkling compared to natural fibers like cotton. Clothing labeled as wrinkle-resistant is popular for its low-maintenance qualities, making it ideal for travel or everyday wear. Fabrics with this feature can save time on ironing and help maintain a polished look throughout the day, appealing to those with busy lifestyles.
