View source for Denier (unit of measure) (nonfiction)

'''Denier''' /ˈdɛnjər/ or den (abbreviated D), a unit of measure for the linear mass density of fibers, is the mass in grams per 9000 meters of the fiber.

The denier is based on a natural reference: a single strand of silk is approximately one denier; a 9000-meter strand of silk weighs about one gram.

The term ''denier'' comes from the French denier, a coin of small value (worth  1⁄12 sou). Applied to yarn, a denier was held to be equal in weight to 1⁄24 ounce (1.2 g).

''Microdenier'' describes filaments that weigh less than 1 g per 9000 m.

There is a difference between filament and total measurements in deniers. Both are defined as above; but the first relates to a single filament of fiber (commonly called denier per filament (DPF)), whereas the second relates to a yarn.

Broader terms, such as ''fine'' may be applied, either because the overall yarn is fine or because fibers within this yarn are thin. A 75-denier yarn is considered fine even if it contains only a few fibers, such as thirty 2.5-denier fibers; but a heavier yarn, such as 150 denier, is considered fine only if its fibers are individually as thin as one denier.
