Modacrylic vs. Polyester — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on April 14, 2024
Modacrylic fibers are known for their flame resistance and softness, ideal for safety applications, while polyester fibers are durable, quick-drying, and widely used in everyday and performance wear.

Key Differences
Modacrylic fibers are synthetic copolymers primarily valued for their high flame resistance, which makes them a top choice for protective clothing and hairpieces. Polyester, on the other hand, is renowned for its strength, durability, and resistance to shrinking and stretching, making it a staple in both casual and performance textiles.
The texture of modacrylic fabric tends to be softer and more flexible, which is why it is often used in faux furs and wigs. Polyester fibers, whereas, are generally stiffer and more suitable for heavy-duty applications like backpacks and curtains, as well as clothing.
Modacrylics are engineered to be non-allergenic and resistant to chemicals and solvents, enhancing their use in industrial environments. Conversely, polyester is also chemical resistant but is less specialized, focusing more on general utility in textiles.
From an environmental standpoint, both fibers are synthetic but modacrylics often require more specialized treatments to achieve their properties, potentially impacting their environmental footprint. Polyester is criticized for environmental concerns, particularly microfiber pollution, but is more commonly recycled.
In terms of care, modacrylic garments require delicate handling, usually needing cool washes and avoidance of heat. Polyester garments are easier to care for, with most being machine washable and dryable at higher temperatures without significant degradation.
