Abstract: Based on the research on weft-knitted seamless sportswear of famous brands on market, the paper sums up their design features and corresponding theory of designing, and discusses two main design considerations: female body fat distribution and heat/moisture distribution of human body. And then, based on the two main design considerations, it points out the design concept of partitioned design of weft-knitted seamless sportswear from the motor function point of view. In the end, it summaries the design approach of new weft-knitted seamless sportswear and applies it in practice by designing a lady’s seamless running suit to verify the feasibility of this concept. The partition design of seamless sportswear based on female body features can be used efficiently in the functional design of weft-knitted seamless sportswear, improving the designing skill and the production efficiency of seamless sportswear, providing reference to designers, enterprises and consumers.

Key words: weft knitting; seamless garment; female body characteristics; partition design
