Abstract

A tubular three-dimensional textile with three layers of longitudinal supporting surfaces arranged therein is used for solving the structure problem of a three-dimensional textile. The warp yarns on the cross section of the textile are arranged to form four parallel square structures, and every two adjacent square structures share a row of warp yarns; and the warp yarns are divided into nine sections (section A, section B, section C, section D, section E, section F, section G, section H and section I) with the six intersecting points of the warp yarns as interfaces, the warp yarns in each section are interwoven inside two layers of weft yarns, and the two weft yarns at the ends of each section are both connected with one of the weft yarn in every two adjacent sections. The composite material formed by filling the tubular three-dimensional textile has the characteristic of high longitudinal rigidity, and can be woven by the use of a common two-dimensional weaving machine, so as to greatly reduce production cost and be favorable for the generalization and application of the tubular three-dimensional textile.

Description

In establish the tubulose stereo fabric of three layers of longitudinal bracing face

Technical field

The utility model relates to the stereo fabric that the woven cross section of a kind of available ordinary two dimensional loom is certain geometrical shape, belongs to textile technology field.

Background technology

Along with the continuous progress and the development of science and technology, various new materials constantly enter people's the visual field, and the appearance of composite material for weaving makes the content of materialogy obtain very big expansion.So-called composite is combined with each other by suitable preparation technology by two kinds or two or more component material, and it is a kind of performance that had not only kept stock blend, but also have the material of the unexistent excellent properties of stock blend.Composite material for weaving be exactly prefabricated component with textile material be base material, the composite that forms by resin compounded.

Early stage composite material for weaving is formed through laminated by two-dimensional fabric, when the member that this material is made surpasses its ultimate strength in external force, the place of Po Huaiing always occurs in interface layer at first, that is interlaminar strength is low, therefore ask for something comparatively the use of harsh occasion composite material for weaving be restricted.The best approach that addresses this problem just is to use three dimensional fabric, three dimensional fabric and General Two-Dimensional fabric maximum different are that it has broken through the restriction of thickness direction, its thickness direction has multilayer, and the yarn by various forms between each layer fabric is connecting, and the mechanical property of fabric is also more satisfactory.In three-dimensional woven fabric, the orthogonal thereto state configuration of the yarn of three systems forms a whole, and this helps making full use of the inherent characteristic of yarn, also can improve DIMENSIONAL STABILITY under external force.The most outstanding characteristics of this structure be the yarn bending less, be that straightened condition is arranged, the fiber strength damage is little more, do almost evenly carrying, the homogeneous deformation of time spent every fiber being subjected to external force, bring into play more fully than two-dimensional fabric mechanical property.Therefore, this structure has very high bursting power, tear resistance and shear resistant, and does not have the splitting problem.

But all be interwoven owing to have the institutional framework of stereo fabric now by warp thread, weft yarn and vertical yarn, its weaving process and required weaving structure more complicated, and equipment is comparatively expensive, makes that the overall cost of material is high.Can use ordinary loom to carry out woven three dimensional fabric if can develop, will make new material in market competition, occupy bigger advantage.

The utility model content

The purpose of this utility model is to overcome the defective of prior art and a kind of tubulose stereo fabric that can use ordinary loom to carry out establishing in woven three layers of longitudinal bracing face is provided.

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

Establish the tubulose stereo fabric of three layers of longitudinal bracing face in a kind of, the warp thread on the fabric cross section is arranged in four " mouth " words arranged side by side, the shared row warp thread of adjacent two " mouth " words; Six intersection points with warp thread are the boundary, warp thread is divided into nine sections, be called A section, B section, C section, D section, E section, F section, G section, H section, I section, every section warp thread interweaves it in the centre by two-layer weft yarn, and two weft yarns of every section termination link to each other with a weft yarn in adjacent two sections respectively.

Establish the tubulose stereo fabric of three layers of longitudinal bracing face in above-mentioned, described two-layer weft yarn is a weft yarn interweaving of circulation, and by following path around knitting on warp thread:

Weft yarn head end-A-F-G-D-I-C-G-E-D-E-I-H-B-F-C-H-A-B-A-weft yarn tail end.

Establish the tubulose stereo fabric of three layers of longitudinal bracing face in above-mentioned, four " mouth " words forming fabric cross section are rectangle, square, trapezoidal and have a polygon of circular arc.

The utility model is the tubulose stereo fabric, and there are three pages of supporting surfaces with the tight weave in of outer rim its inside as skeleton, and cross section has four tube chambers arranged side by side, has the strong characteristics of vertical rigidity through filling the composite material that forms.The packing space of this fabric has four, can be by increasing and decreasing the big or small of a certain zone or changing the purpose that the supporting surface structural material reaches the integrated carrying ability of adjusting section bar.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, greatly reduce production cost, help the promotion and application of this fabric.

The utility model has increased new a member for three dimension stereo fabric family, it weaves with low cost, the yarn selection range is wide, can be as raw material, so can better satisfy the demand of fields such as physical culture, building to different performance three dimension stereo fabric prefabricated component as cotton, chemical fibre, wire etc.
