Abstract:

Six pieces of fabrics with different yarns and densities were selected to analyze the structure of weft knitted jacquard fabric in colors, and the ideal model of loop was obtained. A Santoni SM-DJ2TS double computer jacquard knitting machine was used to weave double jacquard fabric with speckle and vertical stripe surface of the reverse side. The face side shows diamond strips when the reverse side is speckle and the face side shows two needles longitudinal strips when the reverse side is vertical stripe due to the fluence of the loop of the reverse. According to the different appearance of fabric rendering effects, 3D microscopy was used to research the deformation law of the loop so as to get the structure model of the loop. The study will supply the theoretical foundation for the weft knitting jacquard fabric color simulation.

Key words: weft knitted, flat jacquard, simulation, structure model
