TEAM Formula H = 0.52L + 0.47S + 0.95D - 0.19M* - 0.45V - 3.5 where H = Hauteur (mm) L = Staple length (mm) S = Staple Strength (N/ktex) D = Fibre Diameter (µm) M* = Adjusted percentage of middle breaks V = Vegetable Matter base (%) VALUE OF TOP EACH 1mm DECREASE IN HAUTEUR 10c/kg LOSS EACH 1% INCREASE IN NOIL 7c/kg LOSS G. Robinson
