Commonly used calculation formulas for textiles
The commonly used calculation formulas for textiles are divided into two types: fixed-length calculation formulas and fixed-weight calculation formulas. Calculation formula for custom length system: (1), Denier (D) =g/L*9000 Where g is the weight of the wire (grams), L is the length of the wire (m) (2), tex (number of )[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) (m) (3), dtex ( dtex): dtex=g/L*9000 where g is the weight of the thread (grams), L is the length of the thread (m) Customized weight calculation formula: (1), metric count (N): N=L/G Wherein G is the weight of the yarn (or silk) (grams), L is the length of the yarn (or silk) (m) (2), inch count (S): S=L/(G*840) where G is the silk thread The weight (pounds), L is the length of the wire (yards) 2. Select the conversion formula: (1), the conversion formula of metric count (N) and denier (D) = 9000/N (2), inch count Conversion formula of number (S) and denier (D) = 5315/S (3), conversion formula of decitex (dtex) and tex (tex): 1tex=10dtex (4), tex (tex) and denier (D) conversion formula: tex=D/9 (5), tex (tex) and imperial count (S) conversion formula: tex=K/S K value: pure cotton yarn K=583.1 Purified fiber K=590.5 Polyester cotton yarn K=587.6 Cotton viscose yarn (75:25) K=584.8 Fiber cotton yarn (50:50) K=587.0 (6), tex (tex) and metric number (N) The conversion formula: tex=1000/N (7), the conversion formula of dtex (dtex) and denier (D): dtex=10D/9 (8), dtex (dtex) and imperial branch Conversion formula of number (S): dtex=10K/S K value: pure cotton yarn K=583.1 purified fiber K=590.5 polyester cotton yarn K=587.6 cotton viscose yarn (75:25)K=584.8 fiber cotton yarn (50:50)K =587.0 (9), the conversion formula of decitex (dtex) and metric count (N): dtex=10000/N (10), the conversion formula of metric centimeter (cm) and imperial inch (inch): 1inch= 2.54cm (11), the conversion formula of metric meter (M) and imperial yard (yd): 1 yard = 0.9144 meters (12), the conversion of silk and satin square meter weight (g/m2) and mummy (m/m) Formula: 1m/m=4.3056g/m2 (13) Conversion formula between the actual weight of silk and pound weight: pound weight (lb) = silk weight per meter (g/m)*0.9144(m/yd)*50( yd)/453.6
Ball Burst Method (ASTM D3787): Steel ball penetration for textiles/films using testers like GT-C02-2.
Hydraulic Method (ISO 13938.1): Fluid pressure on rubber diaphragm for industrial fabrics via GT-C12A.
Pneumatic Method (ISO 13938.2): Compressed air for breathable materials tested with GT-C12B.
