Description
Technical Field
The invention belongs to the field of textile machinery, relates to a process and a device for realizing a three-dimensional multi-layer copying woven fabric in a high-performance fiber composite material, and particularly relates to a method and a device for realizing weft-wise sinking of the three-dimensional multi-layer copying woven fabric.
Background
In recent years, in the field of composite materials, the use of three-dimensional woven preforms made of high-performance fibers as reinforcement for composite materials has been more widely used. Compared with the schemes of layering, winding, weaving and the like, the three-dimensional weaving machine has the advantages of integral forming, integral stress, no layering and better mechanical property. However, three-dimensional weaving is difficult to produce, and particularly, the drop yarns, i.e., the yarns in the third dimension perpendicular to the plane of the warp yarns and the weft yarns, need a low-cost and high-efficiency weaving method.
Most of the existing three-dimensional multilayer woven fabrics are 2.5D fabrics, namely, the connection between layers is realized in a multilayer angle interlocking mode, and the three-dimensional multilayer woven fabrics are not real 3D fabrics because no drop yarns are woven in. Therefore, to realize true 3D weaving, the problem of the weaving-in of the drop yarns must be solved. For the vertical yarns in the three-dimensional weaving, the vertical yarns are required to be vertical to the plane of the warp yarns and the weft yarns, and are required to continuously penetrate through the upper thickness surface and the lower thickness surface of the whole fabric in a tensioning manner, so that the integral restraint of the multilayer fabric formed by interweaving a plurality of layers of warp yarns and weft yarns in the thickness direction of the lamination layer is formed, and the fiber reinforcement in the third dimension is formed. It is also known in the art to refer to the drop yarns as "binder yarns," which expresses the binding of the drop yarns to the multilayer fabric in the direction of the layer thickness.
Therefore, the weaving of the drop yarns has two meanings: firstly, the distribution of reinforced fibers of the fabric in the third dimension direction is increased, which is a problem that cannot be solved by traditional forming schemes such as layering, winding and silk laying; and secondly, the tows in the thickness direction of the fabric layer are compressed and tightened by utilizing the tension generated when the vertical yarns are continuously woven in a penetrating manner, so that the three-dimensional woven fabric which is higher in compactness, higher in mechanical strength, stronger in resistance to stress deformation in each direction and more accurate in appearance forming can be obtained, and the three-dimensional woven fabric cannot be obtained by the traditional weaving process and the 2.5D process.

the double-position beating-up device can realize the pre-beating-up action of reserving a yarn (weft density) distance between the beating-up reed and the cloth fell and can realize the normal beating-up action of the beating-up reed moving to the cloth fell position;
the weft-wise drooping yarns are actually changed from weft yarns, so that the weft-wise drooping device can be shared with or separately arranged from the multilayer weft insertion devices, namely the weft-wise drooping device and the multilayer weft insertion devices can share one weft insertion device or can be separately arranged with two weft insertion devices, and one weft insertion device is changed into the weft-wise drooping device, so that the purposes of low cost and easiness in realization are achieved, and each loom is provided with the weft insertion device.
Referring to fig. 1, a method for realizing weft direction vertical yarns of a three-dimensional multi-layer profiling woven fabric comprises the following steps:
the length expression of the consumed yarn of the weft-wise vertical yarns in the fabric fell is as follows:
in the formula, L is the yarn length consumed by the weft-wise vertical yarns in the weaving opening of the fabric, namely the yarn feeding amount of the weft-wise vertical yarns of one shuttle, n is the number of warp yarns, m1 is the number of upward flyings, m2 is the number of downward flyings, the flyings are the number of warp yarns crossed by the vertical yarns on the surface of the fabric, d is the thickness of the fabric, and k is the width of the fabric;
when m = m1 + m2, the weft yarns are consumed in the fabric fell by the formula:
in the formula, L is the yarn length consumed by the weft-wise vertical yarns in a fabric weaving opening, namely the yarn sending amount of the weft-wise vertical yarns, n is the number of warp yarns, m is the total number of flyings, namely the sum of the number of flyings, d is the thickness of the fabric, and k is the width of the fabric;
step 4, opening the loom opening device according to the drop thread plate B to form a shed B, namely a drop shed; continuously stretching the yarns in the weaving opening in the thickness direction of the fabric, and simultaneously supplying the yarns at two sides of the weaving opening;
step 5, leveling heald of a loom shedding device, and executing beating-up action 2 by a beating-up device, namely normal beating-up;
step 6, if the shuttle-type verticality guiding is adopted, the vertical guiding of the weft vertical yarns of the current shuttle is finished; if the shuttle does not draw the verticality, cutting off the yarns, and finishing the drawing of the weft vertical yarns of the current shuttle; thereby forming the fill-wise ravels continuously throughout the thickness of the fabric layer.
Further, after the pattern plate instruction is read, if the pattern plate is not the draping pattern plate, the multi-layer weft insertion device executes weft insertion action, then the loom shedding device is flat-heald, and the weft insertion device executes normal weft insertion action.
Furthermore, the ultra-width yarns mean that the moving distance of the weft-wise draping device of the weaving machine exceeds the weft-wise width of the fabric.
The super width yarn is proposed relative to the weft yarn, because the weft yarn is always of the same width, and has the length k, and the length of the vertical yarn is more than one piece related to the layer thickness d in the expression, so that the length of the vertical yarn required for supplying the bending and stretching of the vertical yarn can be formed only if the super width draws the vertical yarn. Because the trailing and weft insertion can share one weft insertion device, the super width and the constant width are important differences of the trailing/weft yarns. This is true for the "shuttle" in weft insertion or in drop insertion, which also corresponds exactly to one stroke of the drop-guiding device, which determines the weft/drop length.
Further, loom latitudinal direction is drawn and is hung device for no shuttle wefting insertion device, no shuttle wefting insertion device is rapier wefting insertion device, rapier wefting insertion device is rigid rapier device, rigid rapier device sets up the right side and the left side at the loom respectively with supplying the yarn device, or rigid rapier device sets up the left side and the right side at the loom respectively with supplying the yarn device, rigid rapier device's rapier passes from the shed, the gripper centre gripping on the rapier supply to withdraw from the shed behind the yarn head on the yarn device and accomplish and draw and hang down.
Further, the weft vertical-leading device of the loom can be a shuttle weft-leading device, yarns are wound on a quill in advance, and the quill is arranged in a shuttle of the shuttle weft-leading device; the moving distance of the shuttle type weft insertion device is the length of the weft-wise vertical yarns.
Furthermore, the loom shedding device is an electronic jacquard capable of realizing a drop shed and a drop shed required by weft-wise drop yarns.
Further, the beating-up device has two beating-up actions of pre-beating-up and normal beating-up, wherein the pre-beating-up represents the distance of a yarn (weft density) reserved between the beating-up reed and the cloth fell, and the normal beating-up represents the movement of the beating-up reed to the cloth fell position.
Referring to fig. 2, fig. 2 shows a schematic drawing of the formation and drop of a drop shed (a-shed) when steps 1 and 2 are performed. As can be seen in fig. 2, the first warp group 1 moves downwards and the second warp group moves upwards to form an intermediate shed, which is a drop-off shed (a-shed), and the drop 2 passes straight through the drop-off shed (a-shed), in fact through the upper surface of the first warp group 1 moving downwards and the lower surface of the second warp group 3 moving upwards.
Referring to fig. 3, fig. 3 shows a schematic view of the first flat heddle beat-up when step 3 is performed. As can be seen in fig. 3, under the action of the warp tension, the warp yarn returns to the flat heddle position, the first warp yarn group 1, which was moving down in the drop shedding (a-shed), moves up, and the second warp yarn group 3, which was moving up in the drop shedding (a-shed), moves down, bending the drop yarns 2, but the warp yarn cannot return completely to the position due to the yarn resistance. The length of the drop in the drop shed (a-shed) is now significantly greater than the fabric width due to the bow between the layers, thus requiring extra-width drop to ensure the drop supply.
Referring to fig. 4, fig. 4 shows a schematic view of the formation of a drop shed (B-shed) when step 4 is performed. As can be seen from fig. 4, the pulling force through the jacquard opening forces the first warp yarn set 1 moving upwards and the second warp yarn set 3 moving downwards into position, overcoming the frictional resistance created by the bending of the drop yarns, creating the situation shown in the figure, where the position of the first warp yarn set 1 is slightly higher than the position of the second warp yarn set 3. At this time, the drop yarns 2 are at the preliminary beat-up position near the fell position, and the warp shedding displacement at this position is relatively small but larger than the displacement at the fell position at the normal beat-up position.
Referring to fig. 5, fig. 5 shows a schematic view of the second flat heddle beat-up when step 5 is performed. As can be seen in fig. 5, the warp yarn sets have returned to their original positions, in which the position of the first warp yarn set 1 is flush with the position of the second warp yarn set 3. Wherein the first warp group 1 goes down (fig. 2) when leading a vertical shed (a-shed), goes up (fig. 4) when pulling a vertical shed (B-shed), and returns to its original position (fig. 5) when leveling; a second group of warp yarns 3 going upwards when drawing a vertical shed (shed a) (fig. 2), going downwards when drawing a vertical shed (shed B) (fig. 4), returning to its original position when leveling (fig. 5); the vertical yarns 2 are third-dimensional yarns perpendicular to the warp and weft planes and penetrating the layer thickness. And as can be seen from fig. 5, the fly-up m1=3 and the fly-down m2=3 for the drop yarns.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
