| Abstract | ||||
| Rapid estimations of diameter minus lumen (D-L), and outer perimeter of cotton fibers (P) in microns, as a biological fineness of Egyptian cotton could be calculated with satisfactory levels of accuracy from hair weight (H.W) in m/tex and maturity ratio )MR) obtained from Micromat data (new F/MT instrument), using the following equations: 2 Circularity x 3.14 x 1.52 Hs (Standard fineness Diameter (microns) or Final format (D) (microns) = 1.205 Hs or Circularit y × 1.52 4 x 3.14 x Hs Perimeter (microns) or Final format (P) (microns) = 3.7853 Hs Results of the current study suggested that more attention should be focused on meaning and measurements of the three values of biological fineness (i.e.) diameter (D), perimeter (P) (microns) and standard fineness (Hs) m/tex. which can be derived from the data obtained from Micromat instrument. | ||||
