Three-dimensional woven hollow layer-connecting fabric

Abstract

The present invention relates to a three-dimensional woven hollow layer-connecting fabric, comprising an upper layer-surface () formed by crossing upper ground warp yarns (), () and a weft yarn () and a lower layer-surface () formed by crossing lower ground warp yarns (), () and a weft yarn (); the weft yarns () and () on the upper and lower layer-surfaces are also crossed with poil warps (), () besides ground warp yarns (), () and (), () on their own layer-surface; the spatial walking direction of poil warps (), () 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.
