Synthetic fabrics are engineered for specific purposes. Polyester is a cost-effective and durable option that works well for everyday use. Nylon stands up extremely well to wear but doesn’t breathe as much as natural fibers. Acrylic is often used as an alternative to wool and resists pilling. Many manufacturers also create blended fabrics, combining natural and synthetic fibers – for example, mixing cotton and polyester to create stronger fabrics.
