Embodiment 1

[0036] 1 to 4, 7 to 9, Example 1 consists of two systems of warp yarns (ground warps 7, 8, 9, 10 and connecting warps 11, 12) and two systems of weft yarns (ground weft 1, 2, 3, 4 and connecting wefts 5, 6) are interwoven or connected between layers. Ground warp (7, 8, 9, 10) and connecting warp (11, 12) respectively form two warp yarn systems; ground weft (1, 2, 3, 4) and connecting weft (5, 6) form two weft yarns respectively system. At the same time, it can also be considered that the two systems of connecting yarns (connecting warps 11, 12 and connecting wefts 5, 6) and two systems of ground weave yarns (ground warp yarns 7, 8, 9, 10 and ground yarns) that are perpendicular to each other Weft yarns 1, 2, 3, 4) are connected or interwoven across layers to connect the fabrics of the upper and lower layers into a whole.

[0037]Among them, the weft yarns (1, 2) of the upper layer and the warp yarns (7, 8) of the upper layer are interwoven to form the upper layer of the holl...

Embodiment 2

[0049] Referring to Fig. 5, Fig. 6 and Fig. 10, this embodiment includes a three-layer structure of an upper layer, a middle layer and a lower layer. The upper ground warp yarns (7, 8) interweave with the upper ground weft yarns (1, 2) to form the upper layer of the fabric, the middle ground warp yarns (17, 18) and the middle ground weft yarns (19, 20) interweave to form the middle plane of the fabric, and the lower ground The warp yarns (9, 10) interweave with the underlying weft yarns (3, 4) to form the lower layer of the fabric. The upper connecting warp yarns (13, 14) also interweave with the middle ground weft yarns (19, 20) across layers while interweaving with the upper ground weft yarns (1, 2), and the lower connecting warp yarns (15, 16) interweave with the middle ground weft yarns ( 19, 20) interweave while crossing layers and weft yarns (3, 4) of the lower layer. The upper connection weft yarn (21,22) also interweaves with the middle layer ground warp yarn (17,18) ...

Abstract

The present invention relates to a longitude-latitude bidirectional cross-layer connected hollow fabric, which comprises an upper layer surface and a lower layer surface and is characterized in that the upper layer surface of the hollow fabric is made by intertexture of upper-layer-surface ground latitudinal yarns and upper-layer-surface ground longitudinal yarns, and the lower layer surface of the hollow fabric is made by intertexture of lower-layer-surface ground latitudinal yarns and lower-layer-surface ground longitudinal yarns; connecting longitudinal yarns and connecting latitudinal yarns mutually and perpendicularly connect with the upper layer surface and the lower layer surface of the fabric in the cross-layer way; the connecting latitudinal yarns, besides interlacing with the ground longitudinal yarns of the upper layer surface, interlace with the longitudinal yarns of the lower layer surface in the cross-layer way; the connecting longitudinal yarns, besides interlacing with the ground latitudinal yarns of the upper layer surface, interlace with the latitudinal yarns of the lower layer surface in the cross-layer way; the connecting longitudinal yarns and the connecting latitudinal yarns are distributed in a X-shaped cross in the mutually perpendicular direction. With a bidirectional support structure, the core structure has the advantages of light weight, excellent bending and pressing resistance, thermal insulation property as well as high specific rigidity and specific strength. The core structure has the functions of impact resistance and energy absorption, and can be widely applied to fields of aeronautics, aerospace, vehicles, ships, architectures, physical education facilities, etc.

Description

technical field [0001] The invention relates to a warp and weft bidirectional cross-layer connection hollow fabric, which belongs to the technical field of multi-layer woven fabrics. Mainly used in composite material reinforced fabrics and other fields. Background technique [0002] In daily textiles, there are: warp pile fabrics, such as warp velvet fabrics (Warp Velvet), plush fabrics (Plush) and warp corduroy fabrics (Corduroy); weft pile fabrics, such as corduroy fabrics (corduroy), velveteen fabrics ( plain-elveteen) and fancy velveteen weave. Their common feature is the use of double-layered weave. According to the design of the fabric structure, the pile warp or pile weft is evenly sandwiched between the upper and lower layers of tissue, and the lower woven fabric is processed by cutting or brushing. [0003] The existing domestic and foreign hollow fabrics are mainly warp yarns connecting the upper and lower fabrics, and foreign countries already have patents for t...
