Abstract:

Based on an in-depth study of classification and form knitting principle of the bottomless and seamless warp knitted fabric, this paper proposed a mathematic model for describing chain notations, threading-in design, jacquard grid and chain effect to conduct the development of software program named WKCAD. Based on the implementation of the functionality of WKCAD, combining with human structure characteristics, a serial of prototype patterns for the design and process of the bottomless and seamless warp knitted fabric was built. Based on the deep study on the corresponding relationship between the knitting structure of the straight barrel shaping warp knitted garments and human body structure, by taking pantyhose as example, 2D prototype patterns in .bmp format which are compatible with the software program for design and process was obtained. Thus, an effective way for new product development of bottomless and seamless warpknitted fabric was developed.

Key words: warp knitting, bottomless and seamless, forming principle, shaping patterns, pantyhose
