| 摘要 |
The present invention relates to a three-dimensional woven hollow layer-connecting fabric, comprising an upper layer-surface (10) formed by crossing upper ground warp yarns (1), (2) and a weft yarn (3) and a lower layer-surface (11) formed by crossing lower ground warp yarns (4), (5) and a weft yarn (6); the weft yarns (3) and (6) on the upper and lower layer-surfaces are also crossed with poil warps (7), (8) besides ground warp yarns (1), (2) and (4), (5) on their own layer-surface; the spatial walking direction of poil warps (7), (8) woven from one layer-surface to another is opposite to the weft-inserting direction of the fabric. The framework feature of the composite layer-connecting fabric of the present invention is distinct, and the vertical support function of poil warps between two layer-surfaces is good. The spatial structure of the layer-connecting fabric is varied in conformation, easy to design and adapted to produce on a large scale. The compositely-strengthened material has the characteristics, such as anti-corrosion, anti-penetration, light weight and excellent physical mechanical properties.
