The weight in grams of 9000 meters of fiber at a given moisture regain. Denier is abbreviated as D. For example, the fiber weight of 9000 meters is 1 gram. When the density of the fiber is constant, the larger the denier, the coarser the fiber. Often used to represent chemical fiber filaments, silk, and the like. Although Daniel is not a metric unit, it is most commonly used. Writing method: Number (plus unit) of × number of shares, such as: 21D×2.
Since the filaments and the yarn are irregular in shape, and the surface of the yarn has hairiness (extended fiber short hair), the diameter is rarely expressed by the diameter, and the denier or the following units are often used. The degree of the thickness of the natural silk or chemical fiber, the weight of the fiber of a certain length indicates that the finer the fiber, the smaller the fineness.
The weight in grams of 1000 meters of fiber at a given moisture regain. The larger the tex, the thicker the yarn. Turks is a metric unit. Since D×1.111=dtex, the denier is similar to the dtex. So dtex is also more common. Writing method: Number (plus unit) × number of shares, such as: 21tex×2
Metric count (N)
The length of meters per gram of heavy fiber or yarn at a given moisture regain. The larger the metric count, the finer the yarn. Writing method: number / number of shares, such as: 32/3
Inch count (S)
At a nominal moisture regain, each pound (0.4536 kg) of fiber or yarn is 840 yards long and one inch. The larger the British branch, the finer the yarn. Writing method: number (plus unit) / number of shares, such as 32S/3
tex *10= dtex
