Example Embodiment
[0031] Example 1
[0032] Using polypropylene monofilament fiber as raw material, after warping, it is designed to change the warp satin structure, two combs, one wear and one empty symmetrical laying yarn, and the fabric weaving parameters are set as GB1: 1-0-1 / 1-2-2 / 2- 3-2 / 2-1-1 / / ; GB2: 2-3-2 / 2-1-1 / 1-0-1 / 1-2-2 / / , the warp knitting holes of the obtained grey fabric are diamond-shaped ( figure 2 ), and the side length of the rhombus is 3 mm. The warp knitting large holes and dividing lines are also knitted and formed on the warp knitting machine. The diameter of the warp knitted large hole is 5mm. The final product is obtained after final shaping.
Example Embodiment
[0033] Example 2
[0034] A rotator cuff patch with a diamond-shaped aperture was prepared in the same manner as described in Example 1 ( image 3 ), only add a third bar for weft insertion during weaving.
Example Embodiment
[0035] Example 3
[0036] Rotator cuff patches with circular holes were prepared in the same manner as described in Example 1 ( Figure 4 ), only adjust the fabric weaving parameters to GB1: 1-0-1 / 1-2-2 / 2-1-2 / 2-3-2 / 2-1-1 / 1-2-1 / / ; GB2: 2-3-2 / 2-1-2 / 2-3-2 / 2-0-1 / 1-2-1 / 1-0-1 / / .
