Abstract
The invention relates to a multilayer woven fabric in which warps can be arranged in a compact but less bent state. The multilayer woven fabric is formed in the mode of connecting two or more than two layers of sublayer fabrics into a whole through connecting warps on the thickness direction of the fabric, so that the connecting warps are only positioned between two adjacent layers of sublayer fabrics, and the connection of the adjacent sublayer fabrics is realized in the mode of superimposing the connecting warps with the warps of the sublayer fabrics in the same fabric longitudinal cross section, wherein the sublayer fabric is structurally formed by interweaving wefts of the sublayer fabric through the special warps of the sublayer fabric in a sinking and floating mode; and the connection of the adjacent sublayer fabrics through the connecting warps is realized in the mode of carrying out sinking and floating interweaving on the warps of the adjacent sublayer fabrics. The multilayer woven fabric has higher tensile modulus and fiber volume density, and the damage of a fabric surface layer is not easily diffused along the thickness direction of the fabric, so that the fabric can be more applicable for the application of high technologies such as aerospace and aviation and the like.
Description
Affiliated technical field
The present invention relates to a kind of multi-ply fabrics, especially warp thread can be closely to lack the multi-ply fabrics that case of bending is arranged.
Background technology
Mentioned woven fabric is meant the fabric that is interwoven in the sink-float mode by filling yarn among the present invention; Multi-ply fabrics is meant the woven fabric with thickness that is interweaved and formed by many groups filling yarn sink-float; The sublayer fabric is meant the individual layer in multi-ply fabrics, but refers to the structurally self-existent fabric of individual layer, and it has self warp thread and weft systems, and promptly the warp thread of this sublayer fabric special use only is woven into cloth to the weft yarn of this sublayer fabric.
At present, how known multi-ply fabrics constitutes in two ways.
First kind of mode is on fabric construction, when there is a plurality of sublayers fabric in thickness direction, have to connect yarn each sublayer fabric is striden the interspersed binding of layer at the thickness direction of fabric, normally stride the interspersed binding of multilayer, this fabric is commonly referred to the 3D multiply cloth.The feature of this mode is, in connecting yarn and the warp thread of sublayer laying respectively at the vertically upward different plane of fabric, promptly can not be in the same fabric longitudinal cross-section on the fabric width (because this fabric is in existing weaving process, sublayer warp thread be connected yarn and must penetrate respectively due to the different healds).This feature has not only caused the deficiency of the arrangement defective tightness of each warp thread on the fabric width direction, influenced the fiber volume density that strengthens body, also exist and connect yarn, can not make full use of the intensity of raw material and the deficiency of modulus because stride the former of multilayer thereby straight inadequately.
The second way is not have the sublayer fabric on the fabric thickness direction, only by the warp thread of two groups of reverse harness motions many weft yarns that are arranged in parallel at thickness direction is interted binding, and this fabric is commonly referred to the 2.5D multiply cloth.The feature of this mode is, warp thread must be striden the motion of multilayer weft yarn, and this feature has caused warp thread to exist than macrobending in fabric and the deficiency that is difficult to arrange closely knitly.
In the above dual mode which kind of no matter also all exists in damage after processing or the local damage in addition easily along the deficiency of fabric thickness direction diffusion, and its reason is to exist the multilayer of striding of warp thread to pass through.
Summary of the invention
For overcome existing multi-ply fabrics warp thread on fabric construction exist than macrobending and be difficult to arrange closely knitly, damage is easily along the deficiency of fabric thickness direction diffusion, the invention provides a kind of multi-ply fabrics, this multi-ply fabrics not only is the whole structure of making, and its warp thread can be with closely and few case of bending be arranged in the fabric, and the damage on fabric top layer is difficult for spreading along the fabric thickness direction.
The technical solution adopted for the present invention to solve the technical problems is: to being used on the fabric thickness direction by connecting warp thread 2 layers and above sublayer fabric are connected into the multi-ply fabrics that whole mode constitutes, make and connect warp thread only between two adjacent sublayer fabrics, and with the superimposed same longitudinal cross-section on the fabric width direction of the warp thread of sublayer fabric in mode, realize connection to this adjacent sublayer fabric.Wherein, the sublayer fabric structurally is by the warp thread of the special use of this sublayer fabric the weft yarn of this sublayer fabric to be risen and fallen to form interweaving of mode; Connecting warp thread connects adjacent sublayer fabric and is to rise and fall with the weft yarn to the adjacent sublayers fabric that the mode that interweaves realizes.For sake of convenience, in the present invention the mode of the integral multi-layered woven fabric of this formation is abbreviated as ways of connecting between warp thread overlapping layers and the layer.
The invention has the beneficial effects as follows, because this multi-ply fabrics structurally, the warp thread of sublayer fabric only interweaves in this sublayer, connecting warp thread only connects between two adjacent sublayer fabrics, and the warp thread that connects warp thread and sublayer fabric is a closed state, its warp thread can be arranged in the fabric closely to lack case of bending, so this multi-ply fabrics has higher stretch modulus and fiber volume density, and the damage on fabric top layer is difficult for spreading along the fabric thickness direction, this is for this fabric serving as the composite that strengthens body, also must improve their mechanical property and service life, make it more can adapt to the purposes of high-tech such as space flight and aviation.

The sink-float and the state that interweaves.
In the present embodiment, the raw material of the warp thread weft yarn of multiply cloth is the 6K carbon fiber of Dong Li company, and structure is integrally-built 5 layers of fabric that 5 sublayer fabric L1, L2, L3, L4, L5 form by thickness; Each sublayer organizational structure of fabrics is identical, is the 1+1 plain weave.Fig. 3 is the superimposed view C of longitudinal cross-section of a circulation of the 1+1 plain weave structure on the fabric width direction of this embodiment, is to be formed by stacking by Fig. 1, two longitudinal cross-section A, B shown in Figure 2; These two longitudinal cross-section A, B have formed the once circulation of the 1+1 plain weave construction on the fabric width direction, and circulation like this has successively just formed the fabric of whole width; Each sublayer fabric all is that the warp thread by two groups of sublayer fabrics constitutes, and the warp thread of first group of sublayer fabric is warp thread Y1, Y2, Y3, Y4, Y5, and the warp thread of second group of sublayer fabric is warp thread Y1 ', Y2 ', Y3 ', Y4 ', Y5 '; Wherein warp thread Y1 and Y1 ' are with the mode of sink-float and the weft yarn of sublayer fabric L1
Interweave and constitute sublayer fabric L1, the weft yarn of warp thread Y2 and Y2 ' and sublayer fabric L2
Interweaving constitutes sublayer fabric L2, and the rest may be inferred by analogy for it.These 5 sublayer fabric L1, L2, L3, L4, L5 are again by two groups of ways of connecting formation integral multilayer fabrics between the warp thread that plays the connection effect between each adjacent sublayer fabric is with warp thread overlapping layers and layer; Represented among Fig. 1 that first group connects warp thread, is warp thread U1, U2, U3, U4; Represented among Fig. 2 that second group connects warp thread, is warp thread U1 ', U2 ', U3 ', U4 '; Wherein, first group of warp thread U1 that connects in the warp thread is connected warp thread U1 ' in the warp thread with the mode that rises and falls and the weft yarn of sublayer fabric L1 and L2 with second group
Interweave, the interlayer that has formed sublayer fabric L1, L2 connects; First group of warp thread U2 that connects in the warp thread is connected warp thread U2 ' in the warp thread with the mode that rises and falls and the weft yarn of sublayer fabric L2 and L3 with second group
Interweave, the interlayer that has formed sublayer fabric L2, L3 connects; By that analogy, just form present embodiment the warp thread overlapping layers and the layer between the connecting-type integral multilayer fabric.
Further, narrate the fabric construction of embodiment from warp opening movement: the warp thread of the arbitrary sublayer fabric two groups of warp thread Y1, Y2, Y3, Y4, Y5 and Y1 ', Y2 ', Y3 ', Y4 ', the Y5 ' is done the opening opposing motion by the plain weave construction rule and is realized weft yarn to this sublayer fabric in 1 scope that strides
Sink-float, around the weft yarn of this sublayer fabric
The cost sublayer that interweaves fabric; Connection warp thread U1, U2, U3, U4 and U1 ', U2 ' between two adjacent sublayer fabrics, U3 ', U4 ' carry out harness motion according to the direction rule that traverse strengthens in company with sublayer fabric warp thread to be realized weft yarn
Sink-float finish the interlayer of adjacent sublayers fabric connected.For example, warp thread Y2, the Y2 ' of the 2nd sublayer fabric L2 does the opening opposing motion by the plain weave construction requirement in 1 scope that strides, realize the weft yarn to the 2nd sublayer fabric
Sink-float, promptly around the weft yarn of the 2nd sublayer fabric
Be woven into the 2nd sublayer fabric L2; Warp thread Y3, the Y3 ' of the 3rd sublayer fabric L3 does the opening opposing motion by the plain weave construction requirement in 1 scope that strides, realize the weft yarn to the 3rd sublayer fabric
Sink-float, promptly around the weft yarn of the 3rd sublayer fabric
Be woven into the 3rd sublayer fabric L3; Can be and between the 2nd sublayer fabric L2 and the 3rd sublayer fabric L3, be equipped with corresponding to warp thread Y2, the Y2 ' of sublayer fabric L2, L3, the trend of arranging of Y3, Y3 ', carry out harness motion in the scope and realize weft yarn but stride the 2nd and the 3rd sublayer fabric two
Connection warp thread U2, the U2 ' of sink-float, promptly this connections warp thread U2, U2 ' according to direction in company with warp thread Y2, Y2 ', Y3, Y3 ' and the rule that traverse strengthens carry out harness motion realize to the 2nd and the 3rd sublayer fabric layer with layer between be connected.So in weaving process, carry out other each sublayer fabric L1, L4, L5 and other connect the motion of warp thread U1, U1 ', U3, U3 ', U4, U4 ' according to above rule, the quilt that just forms embodiment plays the connection effect between the adjacent sublayers fabric 4 layers of warp thread connect into the integrally-built fabric of being made by 5 sublayer fabrics.Because the arbitrary connection warp thread in fabric is not staggered with the warp thread generation of any sublayer fabric, but with warp thread by the adjacent sublayers fabric, so on the fabric width direction, the form of actual fabric is respectively connecting warp thread and can partially or completely embed in the warp thread of sublayer fabric in superimposed mode in the fabric, can reach the compact arranged purpose of all yarns of fabric warp-wise.
Sum up it, above narration and Fig. 1,2,3 have just represented the structure of 5 layers of woven fabric of the integral body that forms with ways of connecting between warp thread overlapping layers and the layer: to being used on the fabric thickness direction by being connected warp thread 5 sublayer fabrics are connected into 5 layers of woven fabric that the mode of integral body constitutes, make and connect warp thread only between two adjacent sublayer fabrics, and with the superimposed same longitudinal cross-section on the fabric width direction of the warp thread of sublayer fabric in mode, realize connection to this adjacent sublayer fabric.Wherein, the sublayer fabric structurally is by the warp thread of the special use of this sublayer fabric the weft yarn of this sublayer fabric to be risen and fallen to form interweaving of mode; Connecting warp thread connects adjacent sublayer fabric and is to rise and fall with the weft yarn to the adjacent sublayers fabric that the mode that interweaves realizes.
