Cotton blended fabrics combine cotton with other fibers like polyester, rayon, or spandex to enhance the material's overall performance and versatility. These blends retain the natural breathability and softness of cotton while adding benefits such as increased durability, wrinkle resistance, and stretchability. Cotton-polyester blends, for instance, are popular for their balance of comfort and strength, making them ideal for everyday clothing and activewear. By integrating different fibers, cotton blends cater to diverse needs, offering improved functionality and comfort for various applications.
