STUDY ON THE DIFFRACTION OF FABRICS—STOCKINGS DIFFRACTION
The microstructures and diffraction patterns of three typical kinds of silk stockings under different external forces were studied in order to provide reference for the study of pho-tonic crystal structure color fabric.Based on the experimental results,three kinds of complex structure models are established,the diffraction intensity expressions are deduced theoretical-ly,and the diffraction patterns are simulated by software.The results show that:(1)the mesh structure of core silk socks can be regarded as a complex structure with large and small circular holes arranged periodically.The mesh structure of velvet socks can be regarded as a complex structure with large and small rectangular holes arranged periodically.The mesh structure of crystal silk stockings can be regarded as a complex structure with periodic ar-rangement of triangular holes and small rectangular holes.(2)When the stockings are evenly stressed,in the case of relatively small force,only the size of the aperture is changed and the shape of the holes and the shape of the diffraction pattern are not much affected.For the crys-tal silk stockings with loose texture,the larger force has a greater influence on the size and shape of the holes.(3)The simulation results agree well with the experimental results.This study has some reference value for the study of the influence of fabric structure on fabric structural color and fabric self-structure structural color.
