"Wrinkle-resistant" refers to fabrics that are designed to resist creasing and maintain a smooth appearance after washing and wearing. This quality is often achieved through special treatments or the use of synthetic fibers like polyester that have inherent properties to repel wrinkles. Clothing labeled as wrinkle-resistant is popular for its low-maintenance nature, making it ideal for travel or busy lifestyles. Many dress shirts, suits, and bed linens are available in wrinkle-resistant options, allowing individuals to look polished without the need for frequent ironing or steaming.
