What does dynel mean?
Dynel is the trade name for a synthetic fiber introduced by the American company Union Carbide in the mid-twentieth century. Chemically a copolymer of acrylonitrile and vinyl chloride, it belongs to the broader family of acrylic and modacrylic fibers that transformed the postwar textile industry. Dynel was prized for its resilience, resistance to moths and mildew, and ability to hold shape and color, making it popular in knitwear, pile fabrics, wigs, and industrial goods such as felts and filters. Like many brand names of its era — nylon and orlon among them — it gradually entered everyday speech as a generic term for the material itself. Today the word survives chiefly in descriptions of vintage clothing and mid-century manufacturing, where encountering 'dynel' on a garment label is a reliable clue to the item's age. It remains a small but telling artifact of the age of miracle fibers.
nounDynel is a proprietary name for a synthetic acrylic fiber produced by the Union Carbide Corporation, used in textiles, wigs, and industrial applications such as filtration and protective clothing.
- A trademarked synthetic acrylic fiber developed by Union Carbide, used in textiles and industrial products.
- Fabric or material made from this fiber.
"The wig was made of dynel, which held its style even after washing."
"Her vintage coat had a lining woven from dynel."

Rarely pluralized; when used, it refers to multiple varieties or batches of the fiber.

Dynel was a registered trade name — a mid-century 'miracle fiber' marketed for everything from sweaters to industrial felt.

Etymology of dynel
Dynel is a coined trade name introduced by the Union Carbide Corporation in the United States around the late 1940s, following the pattern of invented, euphonic names typical of the new synthetic fibers. It has no deeper linguistic root or cognates; its origin is commercial rather than classical. As with nylon and orlon, the name passed into common usage as a lowercase term for the material itself.
How dynel is actually used
Dynel is a capitalized trade name, though it is often lowercased in general usage like other former trademarks (cf. nylon, aspirin). It is now largely historical, as production ceased decades ago; modern readers encounter it mainly in discussions of vintage textiles.
Easily confused with dynel
Nylon is a polyamide fiber from a different chemical family, whereas dynel is an acrylic-type copolymer fiber.
