Research on parametric design of men's suit lapel based on knowledge

PurposeThe purpose of this paper is to improve the efficiency of pattern-making for suit lapels in the apparel industry, to master the perceptual knowledge of suit lapels and to establish a mapping relationship between suit lapel styles and perceptual judgment.Design/methodology/approachIn this paper, notch lapel, peak lapel and shawl lapel are studied, and the authors extract the structural features in the order of drafting as the input values for model training. At the same time, after the expert screening, four perceptual evaluation dimensions based on a priori knowledge are selected as output values, which are finally classified using a decision tree algorithm.FindingsThe results show that different design parameters produce different perceptions of people's vision and, thus, different perceptual judgments. The decision tree model can effectively classify the perceptual judgment of the lapel shape.Originality/valueThe findings of this study help garment factories to provide optimal judgment of basic parameters before the production of a suit lapel and to improve the efficiency of the design.
