Abstract


A bunch of parallel rays perpendicular to the the cylindrical fiber axis irradiation light into the fiber twice refracted and once inside surface reflection outgoing incident ray called a shaft of light ( light reflected back along the same route through the fiber cross-section center deviated from the axis of the light farther ), it passes through the fiber emitted light with respect to the angle between the direction of incident light , the greater the angle reaches a certain position reaches the maximum value , after which angle begins to decrease , the maximum angle position of the light is called the cylindrical fiber Descartes line. This phenomenon is known as the cylindrical fibers Cartesian line phenomenon . Reflective fabric and cylindrical regression fiber in the textile field mentioned Cartesian lines , but mainly to study the respective reflective properties of Descartes line no study reported in this particular light , between this paper main system the cylindrical fibers Cartesian line of research . The specific following aspects : first , the rainbow phenomenon Cartesian line structure of the water droplets , performance , and by the light conditions were analyzed to establish the physical model of the fiber ; Second, the fibers in different light conditions analysis drawn fibers Cartesian line conditions , the mechanism and the factors that affect the fiber Descartes line ; third , the design of experimental schematic , homemade experimental apparatus , the results of the theoretical analysis of the measured and experimental validation of internal reflection of light distribution trends , the Descartes near the line of light intensity larger changes in test analysis reveals Descartes unique line of optical properties and law . The results not only for the quality of the production regression reflective fabric according recognize similar structural fibers reflective nature of the fiber gloss improvements and chemical fiber clothing fabrics visual style to enhance the development of special reflective properties of fiber has important theoretical and guiding significance. Finally, the prospect of this subject in the future development direction and vision .
