Embodiment Construction
[0048] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0049] see Figure 1 to Figure 12 As shown, the present invention provides a special-shaped braid, including several horizontal layers stacked, several connecting yarns passing through the several horizontal layers in the vertical direction, and warp knitting formed on the several connecting yarns by the several connecting yarns. A capping layer connecting the ends of the yarn. The horizontal layer is formed by twist braiding of two yarns 10, 20, and there is a gap between adjacent interlacing points for the connecting yarn 30 to pass through, and the two yarns 10, 20 are braided layer by layer to form several In the horizontal layer, several co...

Abstract
The invention provides a special-shaped braided fabric and a weaving method thereof. The special-shaped braided fabric comprises a plurality of stacked horizontal layers, a plurality of connecting yarns penetrating through the multiple horizontal layers in the vertical direction, and top sealing layers formed at the two ends of each of the multiple connecting yarns through warp knitting of the connecting yarns, wherein the horizontal layers are formed by twisting and weaving two strands of yarns; gaps for the connecting yarns to penetrate through are formed between adjacent staggered points; the two strands of yarns are woven layer by layer to form the plurality of horizontal layers; and the plurality of connecting yarns correspondingly and sequentially penetrate through the gaps in the horizontal layers layer by layer and then are fixedly connected through warp knitting to form the integrated special-shaped braided fabric. The special-shaped braided fabric has good elastic resilience, dimensional stability, shock resistance and impact resistance; the weaving method is easy to operate; special-shaped braided fabrics with any thickness and shape can be woven according to needs; and the application range is wide.
Description
technical field [0001] The invention relates to the textile field, in particular to a special-shaped braided fabric and a weaving method thereof. Background technique [0002] At present, conventional braids only have 2 or 3 layers, and are in the form of planar blocks. The multi-layer braid is only composed of 2-3 layers of plain weave. This multi-layer braid has the disadvantages of low connection strength between layers, easy dispersion, low impact damage tolerance, and poor mechanical properties. [0003] 3D printing is also called additive manufacturing technology or rapid prototyping (RP). The principle is to decompose the three-dimensional model designed by the computer into several layers of plane slices, and then stack the printing materials layer by layer according to the slice graphics, and finally accumulate them into a complete object. In recent years, scholars have begun to try to use 3D printing technology to manufacture three-dimensional fabric structures. ...
