Abstract: According to the characteristics of fabric printing pattern,the methods of IFS(iterated function system) random iteration algorithm which features more simple and fast,scientific and visual during programming were used in this article.While the principles of drawing IFS graphics were discussed with using random iteration algorithm,the basic methods to make IFS graphics vary by changing IFS parameters were investigated.On this basis,employing IFS graphical methods of computer,preliminary trial was performed to apply the theory of IFS random iteration algorithm to fabric pattern design and printing experiment was carried out by means of electronic printing jet.Thus,the approach to printing fabric by using the resources of IFS graphics was investigated.
