Embodiment 1
[0049] Design a bias normal reinforced 2.5D fabric (see figure 2 ). The fabric adopts the angle interlocking structure of diagonal normal reinforced layers, including 5 layers of warp yarn 1 and 6 layers of weft yarn 2;
[0050] The number of wefts required for the normal yarn to complete one interweaving cycle: 2 wefts.
[0051] 1) Initial yarn arrangement. The warp yarns are arranged in 5 layers, and 5 layers and 5 columns are selected for illustration (see Figure 5 ), ○ stands for warp yarns in odd columns, ● stands for warp yarns in even columns, ①-⑧ stands for normal yarns. Wherein the warp thread of ○ representative penetrates in a heald frame 4, the warp thread of ● representative penetrates in another heald frame 5, and the normal direction yarn of ①-⑧ representative penetrates on the yarn carrying device arranged around.
[0052] 2) The first warp shedding movement. The heald raising device controls a heald frame 4 to move up the position of a warp yarn, contro...
