The fabric drape refer sagging performance of the fabric due to its own weight, reflecting the extent and drape of the fabric of the drape. As an important aspect of the fabric style, awareness of it, and study the relationship between the choice of materials to the new fabric development, garment processing, production, computer drape simulation until many aspects based on stand-alone or network of three-dimensional fitting system as well as clothing sales . View, the mechanics, the study of the impact of the study of the structural parameters of the degree of fabric drape has reached a very deep level, while the the drape shape affect the mechanical properties of the fabric itself rarely. Yarn, the structure and mechanical properties of the fiber is indirectly affect the drape of the fabric, the mechanical properties of the fabric itself (shear stiffness, bending stiffness, interleaving resistance, etc.) directly reflects the performance of a variety of yarns, fibers, directly affect the drape of the fabric. To some extent, the mechanical properties of the fabric erected yarn, a bridge between the performance of the fiber and fabric drape performance, its research conducive macro qualitative and quantitative analysis of the performance of the fabric drape. Therefore, the combination of fabric mechanical properties and drape, to identify the key factors that affect the drape shape and provide a valuable reference for the realization of the computer simulations of the drape, garment CAD design. This article briefly reviews the main research directions and research status of fabric drape, introduces the relationship between of fabric mechanical performance indicators drape drape shape prediction equation obtained by experimental analysis, and application of the equation to which the simulation program, VC platform, the computer simulation of the drape, The main complete the work as follows: 1, research and analysis fabric drape instability reasons put forward to improve the testing methods of the destabilizing factors. 2, through the main factor analysis method is extracted from the nine indicators reflect the drape of the fabric, three main factors: the the drape shape factor, the symmetry factor, degree of fabric drape factor drape. Cumulative contribution of these three factors of up to 94.52%, and the high degree reflects the information contained by the drape of the fabric. The integration of the original nine variable is three, to achieve the purpose of the factor analysis. 3, using the linear regression method to study the mechanical properties of the fabric, the intrinsic relationship between the structural parameters drape established drape shape prediction equations based on mechanical properties, and in the course of the study found that the fabric drape fabric mechanical properties closely related to, the the fabric 450 direction shear stiffness, the warp and weft interwoven resistance, thickness and the zonal density of different will cause tremendous changes in the appearance of the fabric drape, impact drape aesthetic. Explore the intertwined resistance differences affect the drape shape symmetry. By curve fitting conclusion that by of fabric interwoven resistance variation size, along with the latitude and longitude to increase the intertwined resistance mutation was logarithmic reduced and polyester fabric polyester fabric and cotton fabric drape evenness evenness of drape better than cotton fabric drape shape symmetry. Therefore, set the appropriate Jingwei to intertwined resistance, to minimize the variability of the warp and weft the aesthetics more conducive to the increase of the fabric drape. 5, in the VC platform, the application overhanging contour analog shape prediction equation based on the mechanical properties obtained and fabric drape contour substantially coincide and the simulation result has a randomness of this point and the drape test results are the same, The general view, the ideal simulation effects.
