Fiber Additives

Textiles are used in a variety of applications and need to meet stringent performance and regulatory requirements. Additives can help by enhancing properties such as; flame retardancy for building and construction applications, UV stabilization for outdoor products, and an antimicrobial effect for hygienic applications. Additives can also be used to improve fiber production processes. Avient offers a wide range of additive concentrates, a.k.a masterbatches, that are specially formulated for spun-dyed filaments and staple fibers, and nonwoven fabrics. Other functional additives include anti-static, antioxidants, optical brighteners, and chain extenders for recycled polyester fibers.
