Sports clothes are required many kinds of functions like elasticity, breathability,water absorption, moisture absorption, heat retention, low surface resistance, etc.depend on the sporting events. In order to add these functions to the product, it needsvarious kinds of raw fibers, fabric structure constructed by complicated method andcutting and sawing into the last. In order to these functions, it is necessary to makechoice of raw fibers and fabric construction optimally. In this procedure, fabric structureis one of the important design factors for the functionalization. On the other hand,the three-dimensional CAD system has been developed in various industrial fields. However in fabric design field, two-dimensional fabric CAD system is mainly used in pattern, decoration and coloring now. The three-dimensional fabric CAD systemdoesn't work in the predictions of physical and functional properties yet. In this study, we investigated the current situation on the fabric CAD system in the world. And wedeveloped a structural design of flat knitted fabric by using the three-dimensional fabric CAD system. Then we examined comparative evaluation between the real knittedfabrics and CAD-designed fabrics, and reviewed about predictability of ventilationperformance.
