Abstract
A method of determining luster characteristics of fiber filaments utilizing a mathematical model of filament cross sectional shape and simulated impinging light to determine light distribution after interaction with the fiber and thereby determine luster properties. The method also includes a method for deriving individual filament cross sectional shapes of fibers in a bundle of touching filaments and for deriving therefrom other fiber properties and controlling the manufacturing parameters affecting such properties as well as luster properties.
