Synthetic fibers and synthetic fabrics consist of bulk fibers, yarns, woven cloth or other textile products manufactured from polymer-based materials such as polyamide (nylon), polyester, aramid, or other spun thermoplastics. Basic product types include: fibers and monofilaments, roving and yarn, carded and needlepunched non-wovens, braided products, rope and cordage, webbing, blankets or batts, sleeves or wraps, and thread. Bulk chopped fibers or thin, continuous fiber filaments are used typically in composite reinforcement applications, flowable insulation, or as the key component in woven fabrics, braids, knits, rope roving or other specialty fabrics. Roving is made of tows, untwisted bundles of continuous filaments. Yarn is made of continuous, often plied strands of natural or man-made fibers or filaments. Carded and needlepunched non-wovens offer very high loft (low density) at very low cost. Braided products are used for tubular composite structures, thermal insulation, and in other applications. Webbing includes ribbons, strapping, and tape. Blankets or batts (batting) are made of thick layers of woven and/or non-woven fabric sheets. Sleeves or wraps (sleeving) are flexible, fibrous refractory products for insulating pipes, tubes, ducts and other process components. Synthetic thread includes both monofilaments and multi-fiber filaments.

Synthetic fibers and synthetic fabrics are made from a variety of materials and may feature a blended, fibrous structure produced by copolymerization. Acetate and triacetate fibers are shrink-resistant and wrinkle-resistant. Acrylic and modacrylic fibers are unique among synthetic fibers and synthetic fabrics because they have an uneven surface. Aramid and polyimide fibers are lighter and tougher than steel. Synthetic fibers that are made of elastomers, fluoropolymers, glass, and fiberglass are also commonly available. Ceramic fibers are designed for high-temperature applications. Metallic fibers have a shiny surface and...
