Unit

1.1, fixed length system:

1.1.1. Turks: The gage of a 1000 m length yarn at a given moisture regain rate is called a special number.
Formula: Ntex = (G/L) × 1000
Where: G is the weight of the yarn (grams), and L is the length of the yarn (meters)

1.1.2. Denier: The mass of 9000 meters of wire at the specified moisture regain is called the denier.
Formula: Nden=(G/L)×9000
Where: G is the weight of the wire (g), L is the length of the wire (m)

1.2, fixed weight system:
1.2.1. Common count (public branch): The length of meters of 1 gram of yarn (silk).
Formula: Nm=L/G
Where: 1 is the length of the yarn (wire) (meter), and G is the weight of the yarn (wire) (g)

1.2.2. British count (British branch): The number of 840 yards of 1 lb. polyester yarn.
Formula: Ne=(L/G)×840
Where: L is the length (code) of the yarn (wire) and G is the weight (in pounds) of the yarn (wire).

2, unit conversion
2.1. Special Ntex and Inch Count Ne Ne=C/ Ntex (C is constant, chemical fiber is 590.5, cotton fiber is 583, if blended yarn can be calculated according to the mixing ratio, such as: T/JC(65/35)45S Yarn C=590.5*65%+583*35%=588, then calculate according to the formula)
2.2. Inch count Ne and metric count Nm Purified fiber: Ne=0.5905Nm Pure cotton: Ne=0.583Nm Blended yarn: such as T/JC(65/35)45S Ne=(0.5905*65%+0.583*35%) Nm

3, special Ntex and metric Nm Ntex × Nm = 1000 4, special Ntex and denier Nden Nden = 9 * Ntex
