Development of CAD system for slub fabric

This paper introduces a CAD system to be used for slub fabric on Windows XP platform.The software is developed based on Visual Basic 6.0 on Windows XP environment.The system includes the slub yarn designing,weave diagram designing and simulating the appearance of slub fabric.The system bases on mathematical model of slub yarn.In the interface of slub yarn,inputting basic parameter of slub yarn,computer can simulate the slub yasrn and simulate the slub fabric in short time.There are some problems of imitation of woven fabrics,and some directions about imitation of woven fabrics are given.
