Spinning Consistency Index (SCI) The equation for the SCI value is: Uniformity Index (Unf) Uniformity Index=Mean Length/ Upper Half Mean Length Short fibre index (SFI) The short fibre index is a value that is calculated using a sophisticated algorithm. The fibro gram is mathematically converted to a length distribution curve. The SFI is an indication of the amount of fibers (%) that are less than 0.5 inch (12.7mm) in length. It correlates very well to the AFIS Content by weight (SFI w) Short fiber Index Description Below 6 Very low 6 to 9 Low 10 to 13 Medium 14 to 17 High 18 and Higher Very high Strength (Str) (CRE=Constant Rate of Extension) and with a 1/8 inch distance between the clamps.
