Establishment of mathematical model on flat collar band width

Flat collar is a kind of special structure of lapel,which has a smaller collar band width.This article mainly analyzes the quantity of overlapped shoulder line based on Japan cultural block in terms of collar band,band curvature and breast.54 samples of flat collar were made,and their band width was measured.Factors influencing the width of flat collar band were analyzed,and a math model for designing the structure and width of flat collars band was developed.The change rule of the structure and width of flat collars band was obtained through the model.
