Abstract

The utility model relates to a stereo multi-layer fabric which is woven by a two-dimensional loom, which belongs to the field of textile technology and is used for solving the problem of weaving stereo multi-layer fabrics by using two-dimensional looms. The fabric is formed from warp yarn and weft yarn which are interwoven and every two layers of warp yarn and the corresponding weft yarn form one layer. After improvement, surface warp yarn in layers below a top layer orderly and separately surround the weft yarn in the layer and the adjacent lower layer, lining warp yarn orderly surround the weft yarn in the layer and the surface warp yarn in the top layer orderly surround the weft yarn in the top layer. The utility model is woven only by the warp yarn and the weft yarn, and the number of layers of compound layers is determined according to the requirements of use. The disadvantage that the existing angular interlocking products of different number of layers have different organizational structures is broken through, therefore the realization of the products of multiple layers becomes simple and feasible. In addition, because hanging yarn is not arranged simultaneously, the utility model can be woven on an ordinary two-dimensional loom, which facilitates the production and processing of the products and reduces production cost. The utility model is suitable to be used as a specially shaped stereo compound board.

Description

Adopt the woven stereoscopic multi-layer fabric of two-dimensional loom

Technical field

The utility model relates to the multiply cloth in the special-shaped stereo fabric, and especially linkage structure multiply cloth in angle belongs to textile technology field.

Background technology

Special-shaped stereo fabric is a newcomer in the field of textiles, can be divided into shape fabric, multiply cloth and vault fabric by the difference of structure type.Stereo fabric interweaves closely, if after processing such as resin filling, can form enhancing property composite again, the performance that good tension pressure, shock resistance and high interlaminar shear strength are arranged, it also is easy to physics, the chemical property of product are further enhanced and improve in conjunction with new raw material, new technology, play defeat a force with a tenderness, with the effect of textile material substituted chemistry plastic products, so be widely used as industry profile in the fields such as Aero-Space, building, fishery, medical treatment, military affairs.

Special-shaped stereoscopic multi-layer fabric is different from two dimensional surface composite bed fabric fully, the latter gets up to form multiply cloth to the multilayer planar fabric that warp and weft interweaving becomes with bondings such as resins, its interlaminar shear strength is lower, and the former makes the warp and weft interweaving layer hand over knot to form by hang down yarn or warp.Hand over the orthohormbic structure multiply cloth of knot or the angle interlock multiply cloth of tying by the warp friendship by the yarn that hangs down, all can make each layer closely interweave, improve interlaminar shear strength, make fabric possess impact resistance good, bear moment of flexure and vibration the time is not prone to characteristics such as cracking delamination.

Just because of stereo fabric has above-mentioned advantage, therefore, it has a wide range of applications in every field, but the stereoscopic multi-layer fabric also has its intrinsic defective, Here it is, and it must adopt the three-dimensional loom of complex and expensive to weave, and production cost is higher, if adopt two-dimensional loom, at present, only can weave the quadrature of 3～5 layers of structure or the fabric of angle interlock.The different numbers of plies has different separately interlaced structure structures, and the number of plies is many more, and pilotaxitic texture is complicated more, also difficult designing more just.Be subjected to the restriction of institutional framework design difficulty and aspect factor such as woven, the number of plies is difficult to increase.Continuous development along with stereo fabric composite Application Areas, requirement to aspects such as the shear strength of three-dimensional multiply cloth, impact resistances is more and more higher, existing product has been difficult to satisfy the demand of industry development, presses for the stereo fabric of the more multi-layered number of research.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of compact conformation and is convenient to adopt the woven stereoscopic multi-layer fabric of two-dimensional loom.

The alleged problem of the utility model realizes with following technical scheme:

The woven stereoscopic multi-layer fabric of a kind of employing two-dimensional loom, warp thread, weft yarn are arranged in the formation, warp thread, weft yarn interweave, every two-layer warp thread and corresponding weft yarn constitute one deck, from top to bottom the capable table that is called of odd number is called back warp through, even numbers row, after the improvement, and each layer that top layer is following, its table is through the A weft yarn in this layer of pile warp and the adjacent lower floor, the back warp B weft yarn in this layer of pile warp successively then at interval successively, the weft yarn of the table of top layer in A1 pile warp top layer successively.

The woven stereoscopic multi-layer fabric of above-mentioned employing two-dimensional loom, the described number of plies is 4～8 layers.

The woven stereoscopic multi-layer fabric of above-mentioned employing two-dimensional loom, the described number of plies is 8 layers.

The utlity model has following characteristics:

1. only be made into filling yarn, the composite bed number of plies can be decided according to user demand, has broken through the disadvantage of the different number of plies different tissues of existing angle interlock product structure, and it is very simple and feasible that the realization that makes multilayer count product becomes;

2. because the yarn that do not hang down makes this infrastructure product knit system on the ordinary two dimensional loom, made things convenient for the production and processing of product, production cost can be controlled in the scope that is easy to receive;

Infrastructure product of the present utility model is suitable to be used as special-shaped three-dimensional composite board.

Description of drawings

Looming draft when Fig. 2 is to use two-dimensional loom to knit system.

Each label is among the figure: A shows warp, the table warp of A1 top layer, B back warp, C weft yarn.

The specific embodiment

Consult Fig. 1, be illustrated as a compound number of plies and be 8 layers fabric.Warp thread, weft yarn are arranged in the formation, warp thread, weft yarn are woven into multilayer, and warp thread and weft yarn are two systems independently separately, form the two-layer up and down of fabric on same board respectively, be called table through, table latitude at the warp thread on upper strata and weft yarn, be called the back warp back weft at the warp thread and the weft yarn of lower floor.Couple together by access node about each layer warp thread between layer and the layer, the method for attachment of this programme is " connecting down ", and when knitting the tabulation layer, back warp is mentioned and shown latitude and interweaves, and the formation access node claims again " back warp access node method ".

Lines A, B represent table in each layer through, back warp respectively among the figure, and stain C represents the weft yarn in each layer, among the figure from top to bottom the capable table that is of odd number be back warp through, even numbers row.Each table through the pile warp route of A is in 2～7 layers: the weft yarn in the weft yarn of the weft yarn of this layer → adjacent lower floor → this layer in the weft yarn → adjacent lower floor at interval The pile warp route of each back warp B is simple relatively in 2～7 layers, directly successively in this layer of pile warp each weft yarn get final product.In the integral fabric, the top layer A of top layer does not participate in interweaving of weft yarn in the adjacent lower floor, only the weft yarn of this layer of pile warp successively.
