Texdenier

Texdenier is a term occasionally used in textile science as a conceptual, non-standard metric intended to bridge the two conventional units for yarn linear density: tex and denier. It is not an officially recognized unit or a standard used in industry specifications.

In standard practice, tex measures mass per length as grams per 1000 meters, while denier measures grams per 9000 meters. For a given yarn sample of length L and mass m, tex equals (m × 1000) / L and denier equals (m × 9000) / L. Consequently, for the same specimen, denier equals nine times tex. A hypothetical texdenier concept would reflect this relationship, but no universal definition or calculation method is established.

As a result, texdenier does not appear in official textile specifications or standards used by manufacturers or standards bodies. It may appear in informal discussions, educational materials, or as a pedagogical shorthand to illustrate the link between tex and denier, rather than as a practical, interchangeable unit in product labeling or quality control.
