Pattern creation and knitted products design based on function Z=ax~c+by~d

Using elementary function,patterns can be created automatically on a computer and applied to design knitted products by computerized knitting machines.This paper choses a dual power exponent function of elementary function Z=axc+byd,converted Z into the integer between 0 and n by formula fij=.Consequently pattern could be created automatically on the computer by using VB program.Here,the value of n represents the number of color showed in the created pattern.When n takes 2,3 and 4,respectively,it means the corresponding pattern was 2-color,3-color or 4-color jacquard structures.Many wonderful patterns can be created with inputting different values of parameter a,b,c and d.According to the knitted structure characteristics,the created pattern can be designed as feasible knitted pattern in view of the knitting machine.The automatic design method can broaden ideas for knitted product design.
