Common units of measurement and conversion standards for textile testing experiments

Textile test experiments are a necessary process in the textile industry Textile test experiments are mainly physical tests, but the measurement of standards must be digitized and assessed, so there must be reference values ​​as comparison standards, so when the results of textile test experiments come out Finally, it is necessary to digital mathematical conversion on the results of the detection and then obtain the desired response. Standard Group (Hong Kong) Co., Ltd. will introduce you the commonly used units of measurement and conversion standards for textile testing experiments.

1. Common calculation formulas for textiles are divided into two types: calculation formulas with a fixed length and formulas with a fixed weight.
Calculation formula of fixed length system:
(1), denier (D): D=g/L*9000 where g is the weight of silk thread (grams), L is the weight of silk thread Length (meters)
(2),tex (number) [tex (H)]: tex=g/L*1000 where g is weight (gram) of yarn (or silk), L is yarn (or thread) length (m)
(3 ), decitex (dtex): dtex=g/L*9000 where g is the weight of the thread (grams), L is the length of the thread ( meters)

2. Select the conversion formula:
(1), the conversion formula of metric count (N) and denier (D): D=9000 / N
(2), imperial count (S) and denier ( D) conversion formula: D=5315/S
(3), decitex (dtex) and tex (tex) conversion formula: 1tex= 10dtex
(4), tex (tex) and denier (D) conversion formula: tex=D/9
(5), tex The conversion formula between Tex (tex) and British 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 size (50:50) K=587.0
(6), the conversion formula of tex (tex) and metric number (N): tex=1000/N
(7), cent tex (dtex) and denier (D) conversion formula: dtex=10D/9
(8), decitex (dtex)and imperial count (S) conversion formula: 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 Dimensional Cotton Yarn (50:50) K=587.0
(9), Ftec The conversion formula of Si (dtex) and metric count (N): dtex=10000/N
(10), metric centimeter (cm) and imperial inch (inch) conversion formula: 1inch=2.54cm
(11), conversion formula of metric meter (M) and imperial yard (yd): 1 yard=0.9144m
(12), side square meter grams The conversion formula of weight ( g/m2) and momme (m/m): 1m/m=4.3056g/m2
(13), the conversion formula of the actual weight of silk and satin and pound weight: pound weight (lb) = silk weight per meter ( g/m)*0.9144(m/yd)*50(yd)/453.6(g/yd)

3. Calculation formula of fixed weight system:

(1), metric count (N): N=L/G where G is yarn (or silk) weight (gram ), L is the length (meters) of yarn (orsilk)

(2), British count (S): S=L/(G*840) where G is weight of silk (pounds), L is length of thread (yard)
