Abstract: Based on the elementary function , pattern could be created automatically by using VB program after the value of Z is transformed with . Many wonderful patterns could be created with inputting different values of parameter a, b, c and d, when n is 2, 3, 4 respectively. Combine the characterastics of knitting machine and knitted structures, created patterns could be designed as feasible knitted patterns. The automatic design method can not only broaden ideas for pattern design, but also suit quick response to market changes.

Key words: elenentary function, VB programming, pattern creation, knitted structure design
