3, fiber calculation method
1 fixed length system:
A. Turks: The weight of a 1000 m length yarn at a given moisture regain rate is called a special number.
Formula: TEX=(G/L)×1000
Where: G is the weight of the yarn (grams), and L is the length of the yarn (meters)
B. Denier: The weight of a 9000 meter long wire at a given moisture regain rate is called the denier.
Formula: NTEX=(G/L)×9000
Where: G is the weight of the wire (g), and L is the length of the wire (m)
2 fixed weight system:
A. Male count (public branch): The length of the meter in 1 gram of yarn (silk). Formula: NM(N)=L/G
Where: 1 is the length of the yarn (wire) (meter), and G is the weight of the yarn (wire) (g)
B. British count (British): The number of 840 yards that a 1 lb. yarn has.
Formula: NE(S)=L/(G×840)
Where: L is the length (code) of the yarn (wire) and G is the weight (in pounds) of the yarn (wire).
