Abstract: Based on a unitary tubular structure, a big breakthrough which a partial tubular flat knitting fabric was developed according to the continuous development of flat knitting machine industry. After building some structures of partial tubular flat knitting fabric, the influencing factor on tubular section was analyzed and the fabric was knitted selectively. The partial tubular flat knitting fabric presents some properties including strong three-dimensional appeal, multiple colored yarn knitting and adjustable appearance structure by changing colored yarn, fabric structure and row number, through studying these structure and process design. It can be known that the partial tubular flat knitting fabric has big market prospects and good application value. At the same time, the partial tubular flat knitting fabric was first put forward and the development was practicable. The industrialization promotion could be carried on later.

Key words: partial tubular, flat knitted fabric, structure and process design, influencing factor
