Abstract:

In order to meet the requirement of online design of flat-knitted fabric, on the basis of conventional flat-knitted computer aided design (CAD), this paper designs and implements the Internet CAD system for flat-knitted fabric based on HTML5 technology. According to the design features and shaping principle of the flat-knitted fabric, the data of pattern and shaping are mathematical modeled and data structure optimized, respectively, and multiple view and shaping process design was realized. Meanwhile, combined with database technology develop the functions of sweater style and pattern custom database. And based on the research of pattern compiling, realize file export. Besides, researched the software architecture, the system is deployed on the server based on the B/S mode and runs on the client. Thus the separation of data process and display is realized. Finally, through the design example of jacquard scarf test the system. And the result proof that the system is intuitive, convenient and efficient for design fabric, meeting the demands of online design of flat-knitted fabrics.
