Abstract: Cowl collar is changeable and widely used in the fashion. Its modeling has close relations with many factors. Five kinds of fabrics with different properties were used in the experiment, their physical properties such as thickness, drape, weight and flexural rigidity were respectively measured. In structure design, with different slashing amount for reference, one-piece cowl collar without plait in shoulder were made of different fabrics, and then related drape data were measured. According to fabric performance, slashing amount and drape data, then the influence of fabric performance and structure parameters on cowl collar’s modeling were analyzed.
