Abstract:

Paper explains a pattern prepare system of double-faced jacquard circular knitting machine based on object-oriented and command pattern is realized , and purposes system general structure and overall design scheme of software data structure. Here presens two decomposition algorithm of pattern bitmap in the case of long floating line and compression algorithm of dissociated data for 3-position(knit,tuck,float) double-faced jacquard circular knitting machine，and implement the conversion from pattern bitmap file to actuator file. The compound action is used to reduce complexity effectively when inputting action and improve the efficiency greatly during designing pattern.

Key words: jacquard circular knitting machine, pattern data preparation, object orientation, algorithm
