Abstract

The utility model relates to a three-dimensional fabric with parallel cavities on a plane, which belongs to the technical field of spinning, and is used for the weaving problem of the three-dimensional fabric. The three-dimensional fabric adopts the technical proposal that a plurality of tubular bodies which are parallel with crosswise yarns are symmetrically distributed on the upper surface and the lower surface of a plane fabric; a shared surface of the upper tubular bodies, the lower tubular bodies and a plane part in the center is formed in the stuck position of the three parts; non-shared parts of the plane part, the shared surface and the tubular bodies are interwoven by crosswise yarns and twist yarns; and the two ends of the twist yarns of the interwoven shared surface and the interwoven non-shared surface of the interwoven upper and lower tubular bodies are connected with the crosswise yarns of the interwoven plane part. When the three-dimensional fabric is adopted to manufacture plate-shaped composite material reinforcement with larger area, the tubular bodies form beams or vertical columns with strengthening ribs at the internal parts after being filled, the required plate strength is achieved, simultaneously, the material consumption can be greatly reduced, and the material cost can be reduced. The three-dimensional fabric can be woven by adopting a common two-dimensional weaving machine, and the production cost is low.

Just because of stereo fabric has above-mentioned advantage, it is all had a wide range of applications in every field, and in the composite material for weaving Application Areas, be accompanied by the continuous development of new technology, the fabric that often needs some special constructions, therefore, developing more, the fabric of multiform shape, structure is the problem that textile technology field needs to be resolved hurrily.

In addition, existing stereo fabric, its institutional framework all is to be interwoven by warp thread, weft yarn and vertical yarn, need to adopt the three-dimensional loom of complex and expensive, or weave, cause weaving very inconvenient through the special loom transformed such as many races loom etc., and the also corresponding increase of production cost, be unfavorable for the research and development of stereo fabric, therefore, the obstacle that this has also caused the stereo fabric new construction to be difficult to come out.

Summary of the invention

The utility model is used to overcome the defective of above-mentioned prior art and the stereo fabric that has parallel tube chamber on a kind of plane is provided.

Problem described in the utility model realizes with following technical proposals:

The stereo fabric that has parallel tube chamber on a kind of plane, it is a plurality of tubular bodies that are parallel to weft yarn that distribute symmetrically on the upper and lower surface of flat fabric, the planar section joint place of upper and lower tubular body and centre forms three's common surface, the non-common sparing of planar section, common surface and tubular body is interwoven by weft yarn and warp thread, and the two ends of the warp thread of the warp thread of the common surface that interweaves and the non-common surface of upper and lower tubular body that interweaves all are connected with the warp thread of interleaved planes part.

The stereo fabric that has parallel tube chamber on the above-mentioned plane, the quantity of the warp thread of the warp thread of the common surface that interweaves, the non-common surface of upper and lower tubular body that interweaves equates, respectively accounts for 1/3rd of interleaved planes part warp thread.

The stereo fabric that has parallel tube chamber on the above-mentioned plane, described tubular body are rectangular tube or semicircle pipe.

The utility model is to weave out in the both sides of flat fabric along the spaced a plurality of tubular bodies parallel with weft yarn of warp thread, its longitudinal section be a plurality of " in " font or the end to end shape of " string " font, when required sheet composition strengthens the area of body when big, adopt this fabric manufacturing, tubular body forms inner crossbeam or the column that has reinforcement after filling, when reaching the sheet material desirable strength, can significantly reduce material consumption, reduce material cost.Owing to have only warp thread and weft yarn in the formation of the present utility model, thereby can utilize common two-dimensional loom to weave, reduced production cost, help the promotion and application of this fabric.
