Special methods • FIBERS Longitudinal views: identification, length, diameter (fibers with round profile), surface faults Cross-sections: area, perimeter – computation of fineness, shape factor, specific surface, degree of cottonization of ultimate flax fibers
Special methods YARNS Longitudinal views: hairiness, diameter, fiber slope, belt fibers of rotor yarn, cover factor of wrapped core yarn, yarn compression between two parallel plates, deformation in simulated binding point Cross-sections: fiber number, packing density, diameter, porosity, blending uniformity, mass (volume) blend portion
