Exploitation Of Special Ease Model For Draping

Draping is the important technique in the apparel industry, but to grasp the essence of it is not so easy. Clothing appearance can be seen directly by draping,including profile, degree of ease, detailing design and so on. But to make high quality clothing, it needs operator's superb skill and more experience. How to reduce the demand of experience to operator, increase draping efficiency and homogeneity is the urgent problem for draping popularization and application.In view of clothing enterprise expanding needs of draping technology and the current situation of difficult to add ease on home-made clean hunman model in draping, author attempted to let the clothing ease transfer to the human model ease, and put forward a new assumption of draping special ease model design.From the development and current situation of body model at home and abroad, author put forward the concept of draping special ease model based on deeply analyzed the type of clothing body model and its applicability. Adopting non-contact 3D human body scan skill, some metrical information can be extracted, such an clean and dressing cross-section shape of the same measured person. Then used MER, graphics rotation, scatterplot's discreteness average and polar fitting and interpolation method to get the ideal cross-section of the human model. After MATLAB program design and man-machine interface design, it realized the comparison and analysis between clean and dressing cross-section, and gave a qualitative and quantitative analysis to ease distribution shape of measured person's torso part.According to the general rules of ease distribution shape and ratio of special clothing profile, author put forward two design means to design draping specific ease model: addition and subtraction. The former is based on clean cross-section of general bodily form to add ease according to specific profile's cross-section ease ratio. The later was restriced to specific profile cross section, and controled ease addition on cross-section of specific bodily form. In the trial-manufacture process of ease model, author pionted out the problem of axes piont's deviation when cross-section graphic was folded up. Through redrawing cross-section graphics in the same coordinate system to adjust the cross-section overlapping shape, and finally achieved the corrected rebuild of body model.Finally, the article introduced the main technological process of ease model trial-manufacture, and draping on the ease model to verify its practicability.
