1. Commonly used textile calculation formulas are divided into two types: fixed-length calculation formulas and fixed-weight calculation formulas.
Fixed length calculation formula:
(1) Denier (D): D=g/L*9000 where g is the weight of the silk thread (grams), and L is the length of the silk thread (meters)
(2), Tex (number) [tex(H)]: tex=g/L*1000 where g is the weight of the yarn (or silk) (grams), L is the length of the yarn (or silk) (meters) )
(3), decitex (dtex): dtex=g/L*9000 where g is the weight of the silk thread (grams), and L is the length of the silk thread (meters)
Fixed weight calculation formula:
(1) Metric count (N): N=L/G where G is the weight of the yarn (or silk) (grams), L is the length of the yarn (or silk) (meters)
(2), British count (S): S=L/(G*840) where G is the weight of the silk thread (pounds), and L is the length of the silk thread (yards)
2. Select the conversion formula:
(1). The conversion formula between metric count (N) and denier (D): D=9000/N
(2) Conversion formula for British count (S) and denier (D): D=5315/S
(3) The conversion formula between dtex and tex: 1tex=10dtex
(4) Conversion formula between tex and denier: tex=D/9
(5) The conversion formula between tex and imperial count (S): tex=K/S K value: pure cotton yarn K=583.1, pure fiber K=590.5, polyester-cotton yarn K=587.6, cotton viscose yarn (75: 25)K=584.8 Cotton yarn (50:50)K=587.0
(6) Conversion formula between tex and metric number (N): tex=1000/N
(7) The conversion formula between decitex (dtex) and denier (D): dtex=10D/9
(8) The conversion formula between decitex (dtex) and imperial count (S): dtex=10K/S K value: pure cotton yarn K=583.1, pure fiber K=590.5, polyester-cotton yarn K=587.6, cotton viscose yarn (75 :25)K=584.8 Cotton yarn (50:50)K=587.0
(9) The conversion formula between decitex (dtex) and metric number (N): dtex=10000/N
(10). The conversion formula between metric centimeters (cm) and imperial inches (inch): 1inch=2.54cm
(11) The conversion formula between metric meters (M) and imperial yards (yd): 1 yard = 0.9144 meters
(12) The conversion formula of satin square meter weight (g/m2) and mmi (m/m): 1m/m=4.3056g/m2
(13) The conversion formula between the actual weight of silk and satin: pound (lb) = weight per meter of silk (g/m)*0.9144 (m/yd)*50 (yd)/453.6 (g/yd)
