Research On Automatic Pattern Making Of Jeans

Jeans style has distinctive characteristics, and pattern design is the key technology to highlight the characteristics of jeans style. The quality and efficiency of the jeans pattern design, directly decide the wearing effect, pricing and sales. Jeans pattern design associated with many factors such as the body figure, the style, fabric performance, washing and so on, but there are strong regularity can be explored. Currently, the domestic jeans pattern design in the industry generally relies on individual experience, and the method is not scientific and systematic enough. So this is not conducive to industrial technology upgrading and enhancing industrial competitiveness. In addition, although CAD technology is popular used in pattern design, according to market research, current domestic manage of CAD technology still stays in the simple use. And compare to abroad auto design, auto production, auto individual custom made, there is a big distance.In order to improve the condition of jeans pattern design too much reliance on individual experience, this paper process an industrial research, and get the key technologies of jeans manufacturing and pattern design. Then, four typical styles of jeans are made by the technologies. Secondly, it summed up the characteristics and commonness of jeans pattern design in different styles, refining the parameters factors of jeans pattern design, such as body figure, fabric feature style character and washing. Finally, it reaches a set of scientific and accurate jeans pattern design method with the combination of pants pattern design theory.In order to improve the condition of CAD technology still stays in the simple use in pattern design, CAD automatic pattern making technology was inducted to realize jean pattern's quick generation both in mass production and custom made. By the aid of CAD modular technology, a special "template" for jeans pattern design is created, the "template" can realize jean pattern's quick and accurate generation with conditions of different body figures, different fabric stretches, and different styles. Finally, four group experiments were designed to verify the accuracy of the pattern design method and CAD automatic generation system. The sample pant and body fitting experiments certificate the "template" can realize jean pattern's quick and accurate generation in conditions of different body figures, different fabric stretches, and different styles and different washing.
