Problems solved by technology

The above-mentioned conventional plate-shaped three-dimensional corner interlocking fabrics are mostly suitable for some conventional plate-shaped materials, or used as flat test pieces of some three-dimensional profiling prefabricated parts; and the weaving method of conventional plate-shaped fabrics has the following defects: 1) The amount of yarn waste is large, which is manifested in, A) during the cutting process, a large number of woven fabrics will be rejected as waste products; In the end, there will be a long part left that cannot participate in the next weaving, resulting in waste; 2) The fiber continuity is not good, and a large number of discontinuous fibers will be produced, which will affect the material properties of the fabric; easy to disconnect
3) The weaving efficiency is low, and a lot of time is wasted in the yarn loading step in the middle of weaving; in some more complex shapes of curved plate materials, such as S-shaped, U-shaped, non-closed ring and other types of materials, due to the limitations of weaving and cannot be used, which limits the development of plate-shaped three-dimensional corner interlocking fabrics

[0050] Such as Figure 5 Shown, adopt the method of the present invention to weave U-shaped fabric.

[0051] Suppose the length of the straight section of the fabric is 10cm, the width is 8cm, the fillet angle θ is 180°, and the fillet inner radius R 2 4cm, outer radius R 1 12cm. Assume that the warp yarn density is 120 / layer / 10cm, the weft yarn density is 3 / layer / 10cm, and the number of fabric layers is 6. Then the inner arc length L 2 is 12.56cm, the outer arc length L 1 is 37.68cm, and the number of weft yarns in a single layer of weaving inner arc length fabric is Z 2 It is 12.56×3=37.68 wefts, rounded up to 38 wefts; weaving outer arc length fabric single-layer weft number Z 1 It is 37.68×3=75.24 latitudes, and rounded to 76 latitudes. Group a is 76 / 38=2 groups, the theoretical minimum rotation angle α 0 The degree is 180° / 38≈4.7°, which is rounded to 5°. For the convenience of weaving, the rotation angle α is set to 6×5°=30°.

Abstract

The invention discloses a curved platelike three-dimensional angle-interlock fabric and a method for weaving the same. The fabric is manufactured by continuously weaving straight-section fabrics and curved-section fabrics at one step; warp yarn of the curved platelike three-dimensional angle-interlock fabric is continuous without broken yarn at any position; bent parts of the curved-section fabrics have fillet structures; and the volume content of the warp yarn used at the round-angle bent positions is the same as that of the warp yarn used at the straight-section positions. The method comprises the following weaving steps of: weaving a straight section; calculating the weaving sequence of fillets according to the fillet size of a product and grouping the warp yarn; then clamping a straight-section plane of a woven fabric by using a clamping tool, rotating the plane at an angle of alpha, weaving by using the grouped warp yarn to form an angle and laminating the angle for multiple times to finish weaving an entire fillet; and finally repeating the previous steps for multiple times to finish weaving the curved platelike three-dimensional angle-interlock fabric. The method has the advantages of simple operation, no broken yarn, weaving time shortened by 1 / 3, high weaving efficiency, wide adaptability and easy implementation.
