Acrylic fibers are synthetic fibers made from a polymer called polyacrylonitrile. They are known for their softness, warmth, and lightweight properties, making them a popular choice for clothing, blankets, and upholstery. Acrylic fibers can mimic the feel of natural fibers like wool, providing a cozy alternative that is often more affordable. These fibers are also resistant to moths, mildew, and sunlight, which enhances their durability. Acrylic is often used in outdoor textiles and activewear due to its moisture-wicking capabilities. Additionally, they can be dyed in vibrant colors, making them versatile for various fashion and design applications.
