With the rapid development of Internet technology, its computer-assisted functions are also rapidly improving and the changes in computer functions have brought great convenience to all the aspects of life. In the clothing industry, the application of computer-aided technology and the production of sample clothing and the rendering of clothing have been introduced. This method greatly shortens the cycle of making and designing clothes and also greatly reduces the workload of the staff. The main content of this article is to explore the influence of the application of CAD on clothing design. Starting from the actual needs of digitally designed clothing, the formation model of clothing and the basis of digital application are derived. In this article, computer-aided technique is used as a modeling development tool and its related functions are introduced through methods such as multideformation modeling and NURBS surface modeling. According to the functional characteristics of the computer-aided dye applicator, it is concluded that the dyeing effect of the model is also diverse, and then the virtual display effect of the digital three-dimensional model of the clothing is obtained. Through the digital design, the clothing design can not only meet the functional requirements but its performance also meets the reliability, stability, and safety. The experimental results show that with the increase of W, the area of the two-dimensional unfolding film gradually increases and the amplitude becomes smaller and finally stabilizes at 0.1263.
