The Application Of 3D Body Models In Bra Pattern Design Optimizing

As the underwear industry of China began from 1980's, its' bra style design and patternmaking lag a lot from European counties which are sophisticated at bra design. Many Chinese underwear industry confirmed that the shortness of qualified bra designer and patternmaker low down the development speed of enterprise. Because the human factors are critical in the structural design of bra, the reasonability of bra structural design should be judged by models trying on. Such process requites high cost of human resources,money and time, those that many Chinese companies cannot afford.The purpose of this thesis was to use 3D body model to optimize bra structural design and pattern development.Through studying east-china women' breasts measurement datum, sets up a three-dimension model of breast, and discuss the relation between 3D-2D transformation and bra structure from the point of Ergonomics.On the basis of prototype pattern, develop a prototype bra pattern as input the theory results of 3D-2D transformation. The structure of prototype bra pattern was modified by virtual stitched and putted on a virtual 3D body model which produced on the standard characteristics parameter of Chinese women, then manufacture a true bra according to the prototype bra pattern. At last a performance evaluation wear of the prototype bra was carried on by real person.This article suggests that the application of virtual design technology may simplify the process of bra design and manufacture. It was the first evaluation study of visualization technology in fashion industry.
