Abstract: To futher improve the ability in developing complex pattern and useing all kinds of technology , this paper discussed the technology in sweater , focus on the technology of Jacquard and Intarsia , a few actual examples were given through M1 plus systerm from STOLL , anlysis weaving process and technical details. Key points of Jacquard pattern design were investigated in terms of useing part , structure , yarn , technology. The study is beneficial for designer to improving design skills of Jacquard fabric and provides reference to Jacquard design innovation.
