Research And Optimization On Structure Of Women’s Elastic Trousers

Garment structure design which has a close connection with production, is a branch of learning in our daily life. Compared to artistic design, it needs to be more scientific and practical. As a connecting tie with the artistic design, structure design is also a subject mixing science with aesthetics ,and technology with art. With the development of new type of fabric represented by elastic fabric, the relationship between human body and garment does not only refer to the matching between garment structure and body shape, but also have something to do with the performance of fabric itself.Close-fitting trousers are closely related to the lower body of human beings. However, the lower parts of different people are very different, which is incompatible with the mass production. As a result, there is a focus on improving the parameters of lower body and pattern optimization based on the elastic fabric.The major of the study is as follow:1. the basic research on the structure of close-fitting trousers. 1) proceeding from the static data which came from the female body measurement, this part used gray system theory to realize the analysis of body based on a tiny amount of samples, and got the mathematical relationship between main parameters and other body parameters by establishing GM(0,h) models.2) beginning with the elements of trousers structure, this part analyzed and studied the structure design of close-fitting trousers without the consideration of loose, and also got a basic pattern of a close-fitting trousers by experimental amendment which preparing for the study of loose.2. research on loose of women’s elastic trousers1) research on the elastic loose. First, research on the mechanical properties was done, which gave a relationship between strain and stress. Second, by establishing a mechanical model as "trousers-streching-pressure",and using descriptive geometry which transformed the mechanical effect into the influence on the trousers structure, a design draft of elastic loose was obtained.2) research on the dynamic loose. Beginning with the dynamic experiment, this part analyzed the dynamic loose, and also got a principle of elastic trousers design, integrating with the conclusion of research on the elastic loose.This article used the method of integrating theory with practice which means basic study integrating with experiments. Therefore, the conclusion is scientific and reliable. Unlike previous study which pay more attention to garment pressure, and less to garment structure, this article emphasized the optimization of trousers structure, by studying the mechanical influence. The conclusion provides a reference to the tight-fitting garment design, and also gives a guidance to the digital garment structure design and 3D fitting system.
