Modacrylic blends are synthetic fabrics made from a combination of modacrylic fibers and other materials, such as cotton or polyester. These blends are known for their softness, durability, and resistance to wrinkles and fading. They are often used in clothing, upholstery, and various industrial applications due to their versatility. One of the key features of modacrylic blends is their flame resistance, making them suitable for protective clothing and safety gear. Additionally, they are lightweight and can be easily dyed, allowing for a wide range of colors and patterns. This makes them popular in both fashion and functional textiles.
