Research On Prototype For Knitwear Depending On The Property Of Knitted Fabric

In the 1970s, Knitted apparel has became a current trend to in the apparel field all over the world. It has attracted more and more attention. These years, as the requirement of knitwear in fashion market has risen in both our country and abroad, the development of knitted apparel in our country has wide prospect. In some areas in our country, it has developed more quickly than the other foreign countries, but if compared with some developed countries, we may find the big differences, especially the structure design theory of the knitted apparel still lagged behind. Many years ago, knitted apparel is mainly based on underwear, but nowadays it pays more attention to other fields. As the development of fashion and clothes, the design methods in knitted apparel, the structure of knitted apparel, and the sewing methods of knitted apparel have all changed much. And it deserves more research on the structure theory of knitted apparel.As the improvement of people's needs, and the change in weave material has taken place, how to do knitted apparel structure design in regard to the characteristics of women's body and the property of knitted fabric is becoming an important question.The thesis's main points are as follows:1. Researching on usually used knitted fabricDo some tests on thickness, weight, density, pendency modulus, stretching power, stretching recovery rate, model distortion ratio, stress relaxation ratio, and take these statistics as the basis for the research of gray mathematic model. Through doing some counting, find the relationship between these statistics and the clothes size.2. Researching on prototype according to different loosen amounts of the bustDo some research on the engender of clothes pressure and analyze the pressure and infection factors. And then do drape cutting according to different loosen amounts of 4cm, 0cm, -6cm, from this research we will find the variation in length, width of clothes, and the variation in loosen amounts both front and back prototype, the differences from front prototype and back prototype, and the variation on shoulder, find the rule and this research is the basis of the knitwear prototype3. Establishing knitwear prototype and analyze infection factorsThrough gray mathematic model, gain the relationship between property of knitted fabric index and the variation of clothes size, establishing knitwear prototype on the basis of drape cutting, analyze the main factors and the detail size of knitwear prototype, discuss the mathematic relationship between clothes pressure and skin stretching rate, different loosen amounts rate of the bust, stretching property of knitted fabric. Gain rules on structure design of knitwear, at last, checkout the correct of the rules.Through combining practice and theory, and on the basis of basic theory research, the last conclusion is reliable and scientific, different from the researching method of woven fabric, this thesis gain knitwear prototype on the background of the conclusion which makes from the compare of different loosen amounts of the bust, and on the background of testing results on different kinds of knitted fabric. And the conclusion is useful to structure design of knitwear, especially for knitwear which is suitable for close-fitting patterns, and it is useful for clothes pressure research.
