Various types of composite silk fabrics having the same size and number of warps and filling yarns per cm were produced from four kinds of warps and two kinds of fillings using the same weaving machine. These composite silk fabrics from wild silk yarn showed different structure from other fabrics tested, even though they had the same two-dimensional lattice and the same weight per area. This was attributable to the difference in thickness and density among these fabrics. The thickness of these composite silk fabrics varies inversely with the apparent density when the weight per area was held to be constant. The optical density was proportional to the thickness of fabrics for the same two-dimensional lattice. Points of filament yarns were not located on the same line in the graph as those of spun yarns. From the optical densities of the threads, opening parts of the composite silk fabrics were different from each other in form and size. Information about structure of silk fabrics was obtained from the optical densities of the threads. Therefore, the optical densities of the threads were used instead of form function of threads. It was assumed that the form function of threads is applied to the structure equation of silk and other fabrics.
