FIBRES FORMULAE | |
Micronaire value of cotton ( Micrograms per inch) |
=Average weight of 1 inch of fibre in Micrograms ( 1/1000,000gms ) |
Denier( for man-made fibres ) | =Weight in gms per 9000 metres of fibre |
Micron ( micro-metre ) (μm)(fibre diameter) (normally for Wool) | =0.001 mm |
Denier | = 0.354 x Micronaire value |
Micronaire Value | =2.824 x Denier |
Fibre diameter (μ)= 11.3 x √ ( dtex / sp.gr)=11.9 x √ ( den / sp.gr) | |
Tenacity values: Kg / mm2 = 9 x (g/den) x Sp.gr. = RKM value x Sp.gr. = ( g/tex ) x Sp.gr. |
TENACITY CONVERSIONS (FIBRE STRENGTH ) | g = gms | |||
g/den | g/tex | g/dtex | cN/tex | |
g/den = | 1 | (g/tex ) / 9 | ( g/dtex ) x 10 / 9 | (cN/tex ) x 0.113 |
g/tex = | (g/den) x 9 | 1 | (g/dtex) x 10 | (cN/tex) x 1.02 |
g/dtex = | (g/den) x 0.9 | (g/tex) / 10 | 1 | (cN/tex) x 0.102 |
cN/tex = | (g/den) / 0.113 | (g/tex) / 1.02 | (g/dtex) / 0.102 | 1
