Abstract:

Warp-knitted three-dimensional structure jacquard shoe-upper has high demand on size of the functional zone. To control the size of the shoe-upper fabrics, four kinds of fabric structure and four kinds of on-loom densities were designed. The influence of the two factors on the whole shoe-upper’s weft shrinkage and warp shrinkage were analyzed. The inflluence of jacquard mesh structure on the local pattern size was also studied. Based on the experimental results, the correspondence among jacquard shoe-upper lateral weft shrinkage, lateral warp shrinkage, size of the mesh area and influence factors was explored, and then a shoe-upper size prediction system was established. Finally, the prediction system is used to design jacquard shoe-upper. Taking one jacquard shoe-upper’s design as an example, after knitting and finishing process, the size of shoes is consistent with the pattern. It is proved that the size prediction system is relatively reliable.
