Description

Technical Field

[0001] This utility model relates to the field of yarn plying and twisting technology, and in particular to a multi-axial warp-knitted reinforced yarn and a device for plying and twisting multiple yarns. Background Technology

[0002] A multi-yarn plying device is a piece of equipment used in the textile industry. It is primarily used to combine multiple yarns into a single strand in a specific manner to improve the yarn's strength, uniformity, and suitability. These devices control the yarn tension, speed, and arrangement to combine multiple yarns into one, thereby producing yarns suitable for various weaving, knitting, or sewing needs. They are widely used in textile, weaving, and knitting production processes, helping to improve production efficiency and ensure the stability of yarn quality.

[0003] A search revealed that CN222181398U discloses a device for plying and twisting multiple yarns, relating to the field of yarn processing technology. The device includes a workbench with a plying mechanism at the center of its top and a winding mechanism on one side of the top. The plying mechanism includes a first U-shaped plate with a first electric telescopic rod at its top and a pressure plate at its telescopic end. The winding mechanism includes a second U-shaped plate with two mounting plates at its top. A circular rotating rod rotates between the two mounting plates, and a square rotating rod is located in the center of the circular rotating rod. A winding roller slides on the surface of the square rotating rod. The beneficial effect of this invention is that the winding roller is rotated by a second motor to wind the plyed yarns. After all the yarns are wound onto the winding roller, all bolts and nuts can be removed, the mounting blocks can be separated from the circular rotating rod, and the winding roller and yarn can slide off the surface of the circular rotating rod, facilitating later use.

[0004] The patent description mentions that "after all the yarn is wound onto the winding roller, all the bolts and nuts can be removed, the mounting block can be separated from the circular rotating rod, and the winding roller and yarn can be slid off the surface of the circular rotating rod." However, disassembling with bolts is cumbersome and does not clean the yarn. This leads to a decrease in yarn quality after plying and adding water, thus affecting subsequent use. Therefore, a multi-axial warp-knitted reinforcing yarn and a plying device for multiple yarns are proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-axial warp-knitted reinforcing yarn and a device for plying and twisting multiple yarns. It aims to improve the problem that the existing technology is cumbersome to disassemble by bolts and does not have the effect of cleaning the yarn, which leads to a decrease in yarn quality after plying and adding water.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multiaxial warp-knitted reinforced yarn includes a yarn body, the yarn body including glass fiber warp yarn, a glass fiber weft yarn disposed on one side of the glass fiber warp yarn, an inner layer of glass fiber yarn disposed on one side of the glass fiber weft yarn, an outer layer of glass fiber yarn disposed on one side of the inner layer of glass fiber yarn, a plurality of sizing agent layers disposed inside the yarn body, and a network yarn disposed outside the yarn body;

[0008] Through the above technical solution, the multi-axial warp-knitted reinforced yarn is composed of glass fiber warp yarn, glass fiber weft yarn, inner layer glass fiber yarn, and outer layer glass fiber yarn, forming a composite structure. The glass fiber warp and weft yarns are arranged orthogonally to provide basic strength, while the inner and outer layer glass fiber yarns overlap at an oblique angle to enhance the mechanical properties in all directions. Multiple wetting agent layers are provided inside to improve resin adhesion and wettability. The outer covering is a network yarn to increase toughness and impact resistance, thereby improving the overall performance. This structural design ensures that the yarn can effectively withstand stress in different directions and meet the reinforcement requirements.

[0009] A multi-yarn plying and twisting device for plying a multiaxial warp-knitted reinforcing yarn as described above, comprising a base, a support frame fixedly connected to the top of the base, a moving mechanism installed on one side of the support frame, a conveying assembly installed on the top of the support frame, a support mechanism installed on the top of the base, and a winding mechanism installed on the top of the base.

[0010] The moving mechanism includes a moving motor, one side of which is fixedly connected to one side of the support frame. A lead screw is fixedly connected to the drive end of the moving motor. A rotating disk is fixedly connected to one side of the lead screw. A rotating rod is rotatably connected to the other end of the rotating disk. A cleaning plate is rotatably connected to the other end of the rotating rod. Adjustment components are fixedly connected to both sides of the top of the base. A threaded block is threaded to the outside of the lead screw. A stranding component is installed on one side of the threaded block.

[0011] The above technical solution involves a mobile motor driving a lead screw to rotate. The rotation of the lead screw causes a rotating rod and a cleaning plate to perform cleaning operations, ensuring the cleanliness and smoothness of the yarn during plying. The plying assembly is fixed on one side of the threaded block. As the lead screw moves, it performs the plying operation on the yarn. The conveying assembly on the support frame is responsible for conveying the yarn to the plying area, while the winding mechanism neatly winds up the plyed yarn for subsequent use. The adjusting assembly is fixed to the support device to ensure the stability of the equipment during operation, thereby effectively improving the efficiency and quality of yarn plying.

[0012] As a further description of the above technical solution:

[0013] The adjustment assembly includes two hydraulic cylinders, which are respectively fixedly connected to the top two sides of the base. The driving end of each hydraulic cylinder is fixedly connected to a moving block. An adjustment roller is rotatably connected to the adjacent side of the two moving blocks. A limiting roller is rotatably connected to the inner wall of the support frame.

[0014] Through the above technical solution: the adjustment component drives the moving block to move through two hydraulic cylinders. The moving block is connected to the adjustment roller to realize the tension adjustment of the yarn. The limiting roller is connected to the inner wall of the support frame to ensure that the yarn maintains appropriate tension and stability during winding or plying.

[0015] As a further description of the above technical solution:

[0016] The stranding assembly includes a stranding motor, one side of which is fixedly connected to one side of the threaded block, the drive end of which is fixedly connected to a rotating disk II, and the other end of which is fixedly connected to a limiting sleeve.

[0017] The above technical solution involves using a plying motor to drive a rotating disk, which is connected to a limiting sleeve. This ensures that the yarn can be twisted and arranged evenly during the plying process, thereby improving the plying quality and ensuring the consistency and stability of the yarn structure.

[0018] As a further description of the above technical solution:

[0019] The conveying assembly includes a storage tank, the bottom of which is fixedly connected to the top of the support frame. A pump is fixedly connected to one side of the storage tank. A connecting pipe is fixedly connected to the output end of the pump. A nozzle is fixedly connected to the other end of the connecting pipe. The outside of the connecting pipe is fixedly connected to the top of the threaded block.

[0020] The above technical solution involves using a pump inside a storage tank to extract liquid, which is then transported to a nozzle via a connecting pipe. The nozzle atomizes the yarn, providing moisture to the yarn and enhancing its toughness, thereby improving the quality and performance of the plying process.

[0021] As a further description of the above technical solution:

[0022] The support mechanism includes two mounting clips, which are respectively fixedly connected to the top two sides of the base, and the inner walls of the two mounting clips are equipped with unwinding rods.

[0023] The above technical solution involves a support mechanism consisting of two mounting clips fixed to both sides of the base. Each mounting clip has an inner wall equipped with a unwinding rod, which can support the yarn roll, allowing the yarn to be smoothly released during the plying process, thus ensuring the stability and continuity of the plying operation.

[0024] As a further description of the above technical solution:

[0025] The winding mechanism includes a support frame, the bottom of which is fixedly connected to the top of the base. A winding motor is fixedly connected to one side of the support frame. A transmission rod is fixedly connected to the drive end of the winding motor. A winding drum is installed outside the transmission rod. An installation plate is installed on one side of the support frame. An extension block is fixedly connected to the bottom of the installation plate. A control rod is slidably connected to one side of the extension block. Both ends of the control rod are rotatably connected to connecting rods. A locking block is rotatably connected to the other end of the connecting rod. A spring is fixedly connected to one side of the control rod. The other end of the spring is fixedly connected to one side of the winding drum.

[0026] The above technical solution involves using a winding motor to drive a transmission rod to rotate, which tightly winds the yarn onto the winding drum. The structure of the control rod and connecting rod allows the locking block to move flexibly, and the springs work together to achieve smooth operation, ensuring a stable and reliable winding process.

[0027] As a further description of the above technical solution:

[0028] The outer side of the card block engages with the inner wall of the support frame, and one side of the transmission rod is rotatably connected to the slot of the mounting plate.

[0029] Through the above technical solution: the locking block engages with the inner wall of the support frame to maintain a stable connection, and one side of the transmission rod rotates through the slot of the mounting plate to achieve flexible movement, ensuring that the winding mechanism can effectively adjust and control the winding state of the yarn during operation.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, a movable motor drives the lead screw to rotate, and the rotation of the lead screw pushes the threaded block to move, thereby driving the movement of the plying assembly to ensure uniform yarn winding. At the same time, the plying motor drives the rotation of the rotating disk and the limiting sleeve to ply the yarn. The rotation of the lead screw also drives the rotation of the rotating rod, which in turn drives the cleaning plate to move back and forth to clean the yarn body. In this process, the cooperation between various structures such as the lead screw, plying motor, rotating rod and cleaning plate makes the cleaning action efficient and precise, ensuring the surface cleanliness of the yarn, reducing the impact of impurities on production, and improving production efficiency and yarn quality stability.

[0032] 2. In this utility model, a more convenient disassembly method is achieved by pulling the control rod. By pulling the control rod, the connecting rod drives the locking block to move, and the locking block exits the inner wall of the extension block, thereby allowing the mounting plate to slide out of one side of the support frame, so that the winding drum can be easily removed. Compared with the bolt disassembly method in traditional technology, this design significantly improves disassembly efficiency, simplifies the operation process, reduces manual labor intensity, and at the same time reduces the time consumption during the disassembly process, thereby improving the working efficiency of the production line and the ease of equipment maintenance.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Reference Figure 6 This utility model provides an embodiment of a multiaxial warp-knitted reinforced yarn, comprising a yarn body 7. The yarn body 7 forms a multiaxial mechanical load-bearing structure through a multi-layered orthogonal and oblique glass fiber stacking design, thereby improving the tensile and shear resistance of the composite material. The yarn body 7 includes glass fiber warp yarns 71, and a glass fiber weft yarn 72 is provided on one side of the glass fiber warp yarns 71. The glass fiber warp yarns 71 and glass fiber weft yarns 72 are arranged orthogonally to form a basic grid skeleton, thereby enhancing the rigidity in the planar direction. An inner layer of glass fiber yarn 73 is provided on one side of the glass fiber weft yarn 72, and an outer layer of glass fiber yarn 74 is provided on one side of the inner layer of glass fiber yarn 73. The inner layer of glass fiber yarn 73 and the outer layer of glass fiber yarn 74 are stacked obliquely to improve the torsional resistance and suppress the risk of interlayer delamination. Multiple sizing agent layers 75 are provided inside the yarn body 7, and a network yarn 76 is provided on the outside of the yarn body 7. The sizing agent layers 75 improve the resin adhesion, and the network yarn 76 enhances the toughness and impact resistance through external wrapping.

[0043] Specifically, the yarn body 7 is composed of glass fiber warp yarns 71 and glass fiber weft yarns 72, forming a basic mesh skeleton to enhance rigidity in the planar direction. The oblique overlapping of the inner glass fiber yarn 73 and the outer glass fiber yarn 74 improves the torsional resistance and reduces the risk of interlayer delamination. The inner wetting agent layer 75 improves the adhesion of the resin, while the outer network yarn 76 enhances the toughness and impact resistance of the yarn, thus improving the overall tensile and shear resistance of the composite material.

[0044] Reference Figures 1 to 3 This multi-yarn plying device is used to ply a multi-axial warp-knitted reinforcing yarn as described above. It includes a base 1, with a support frame 2 fixedly connected to the top of the base 1. The support frame 2 provides stable support for the entire device, ensuring the coordinated operation of all components during operation. A moving mechanism 3 is installed on one side of the support frame 2, allowing for flexible movement and providing necessary adjustment space for plying operations to handle yarns of different specifications. A conveying component 4 is installed on the top of the support frame 2, responsible for conveying the yarn from the storage area to the plying area, improving the efficiency of the integration process and reducing manual operation. A support mechanism 5 is installed on the top of the base 1, ensuring the yarn maintains appropriate tension during plying to prevent slack or knotting. A winding mechanism 6 is installed on the top of the base 1, responsible for neatly winding the plyed yarn for convenient subsequent transportation and use, improving the continuity of the workflow. The moving mechanism 3 includes a moving motor 31, which is electrically driven and can quickly adjust its position to meet different operational needs. One side of the moving motor 31 is fixedly connected to one side of the support frame 2. This layout ensures that the operation of the moving motor 31 will not affect the operation of other components, thus improving the stability of the overall device. The drive end of the moving motor 31 is fixedly connected to the lead screw 32. The rotation of the lead screw 32 drives the moving mechanism 3 to move back and forth, ensuring precise adjustment of the plying position. One side of the lead screw 32 is threadedly connected to the threaded block 37. The design of the threaded block 37 allows it to move freely on the lead screw 32, providing flexibility and stability for position adjustment. One side of the threaded block 37 is installed with the plying component 38, which is responsible for plying multiple yarns, helping to improve the structural strength and toughness of the composite material. One side of the lead screw 32 is fixedly connected to the rotating disk 33. The other end of the rotating disk 33 is rotatably connected to the rotating rod 34. The other end of the rotating rod 34 is rotatably connected to the cleaning plate 35. The cleaning plate 35 can be used to clean the yarn debris generated during the plying process, keeping the working environment clean and improving product quality. The top two sides of the base 1 are fixedly connected to the adjustment components 36. The adjustment components 36 adjust the tension and position of the yarn to ensure the smoothness of the plying process.

[0045] Specifically, the base 1 supports multiple components to ensure stable operation, the moving mechanism 3 flexibly adjusts its position to adapt to the plying operation of yarns of different specifications, the conveying component 4 efficiently conveys the yarn to the plying area, the supporting mechanism 5 maintains tension to prevent slack or knotting, the winding mechanism 6 neatly winds up the plyed yarn, the adjusting component 36 ensures that the yarn tension is moderate and the plying process is smooth, the moving motor 31 and the lead screw 32 precisely adjust their positions, the plying component 38 improves the strength of the composite material, and the cleaning plate 35 maintains a clean working environment.

[0046] The adjusting component 36 includes two hydraulic cylinders 361. These two hydraulic cylinders 361 are hydraulically driven and can adjust their height and position to change the tension and tightness of the yarn. The two hydraulic cylinders 361 are fixedly connected to the top two sides of the base 1. This layout ensures the stability of the adjusting component 36 and avoids deviations in the yarn during unwinding or winding. The driving end of the hydraulic cylinder 361 is fixedly connected to a moving block 362. The moving block 362 can move up or down under the drive of the hydraulic cylinder 361, thereby achieving precise adjustment of the yarn tension. An adjusting roller 363 is rotatably connected to the adjacent side of the two moving blocks 362. The adjusting roller 363 is responsible for contacting the yarn. By rotating the adjusting roller 363, the unwinding and winding state of the yarn can be effectively changed, improving the flexibility of the plying operation. A limiting roller 364 is rotatably connected to the inner wall of the support frame 2. The limiting roller 364 can effectively limit the movement of the yarn during the adjustment process, ensuring its stability during winding or unwinding and avoiding knotting or loosening.

[0047] Specifically, the adjusting component 36 drives the moving block 362 through two hydraulic cylinders 361 to achieve precise control of yarn tension. The arrangement of the hydraulic cylinders 361 ensures the stability of the adjusting component 36 and avoids tension deviation. The up and down movement of the moving block 362 drives the adjusting roller 363 to contact the yarn and flexibly change the unwinding and winding state of the yarn. The limiting roller 364 on the inner wall of the support frame 2 effectively limits the movement of the yarn, ensuring stability during winding or unwinding, avoiding knotting or loosening, and improving the quality and efficiency of plying operations.

[0048] The plying assembly 38 includes a plying motor 381, which is electrically driven and can effectively control the clamping and release of yarn during the plying process, achieving precise plying operation. One side of the plying motor 381 is fixedly connected to one side of the threaded block 37. This connection method allows the movement of the plying motor 381 to directly affect the threaded block 37, ensuring good stability and coordination during operation. The drive end of the plying motor 381 is fixedly connected to a rotating disk 382. The rotating disk 382 transmits power through rotational movement, making the plying process smoother and adjusting the tightness and uniformity of the yarn. The other end of the rotating disk 382 is fixedly connected to a limiting sleeve 383. The limiting sleeve 383 is designed to limit the movement of the yarn, ensuring that slippage does not occur during plying and maintaining plying consistency.

[0049] The conveying assembly 4 includes a storage box 41 for holding the yarn to be processed, ensuring that the yarn is readily available during the plying process and avoiding material waste. The bottom of the storage box 41 is fixedly connected to the top of the support frame 2. This layout improves the stability of the entire device and places the storage space above the operating area, helping to save space. A extraction pump 42 is fixedly connected to one side of the storage box 41. The extraction pump 42 is responsible for extracting the yarn from the storage box 41 and pushing it towards the plying area, providing convenient operation. The extraction pump 42 conveys... The outlet end is fixedly connected to a connecting pipe 43, which serves as a transmission channel to effectively transmit the power of the extraction pump 42 to the nozzle 44, ensuring that the yarn is smoothly delivered to the longitudinal plying position. The other end of the connecting pipe 43 is fixedly connected to the nozzle 44. The nozzle 44 is designed to adjust the speed and direction of the yarn ejection, precisely control the flow state of the yarn during the plying process, and ensure plying accuracy. The external connection of the connecting pipe 43 is fixedly connected to the top of the threaded block 37. This fixing method ensures the stability of the connecting pipe, so that the yarn always maintains appropriate tension and position during plying.

[0050] The support mechanism 5 includes two mounting clips 51, which are used to securely fix the yarns and ensure that they do not shift during the plying process, keeping the operating environment tidy. The two mounting clips 51 are fixedly connected to the top two sides of the base 1 respectively. This layout improves the fixing effect of the yarns and ensures symmetrical tension distribution during the plying process, avoiding uneven plying. The inner walls of the two mounting clips 51 are equipped with unwinding rods 52. The function of the unwinding rods 52 is to release the yarns in an orderly manner, ensuring that the yarns are always in the best condition during plying and improving the smoothness of the plying operation.

[0051] Specifically, the plying assembly 38 precisely controls the clamping and release of the yarn through the plying motor 381, achieving efficient and stable plying operation. The plying motor 381 is connected to the threaded block 37, so that the motor movement directly affects the yarn tension, maintaining operational stability. The motor-driven rotating disk 382 controls the yarn tightness by rotation, ensuring a smooth plying process. The limiting sleeve 383 prevents yarn slippage, ensuring plying consistency. The conveying assembly 4 includes a storage box 41 for storing the yarn to be processed, reducing material waste, and conveys the yarn to the plying area through the extraction pump 42, improving work efficiency. The connecting pipe 43 and the nozzle 44 ensure that the yarn flows at a suitable speed and direction, maintaining plying accuracy. The support mechanism 5 stabilizes the yarn through the mounting clamp 51 and the unwinding rod 52, ensuring that it does not shift during the plying process, thereby achieving uniform tension distribution and improving operational smoothness.

[0052] The winding mechanism 6 includes a support frame 61, which not only provides structural support but also ensures the stability of the entire winding process and adapts to different operating conditions. The bottom of the support frame 61 is fixedly connected to the top of the base 1. This design improves the overall rigidity of the equipment and minimizes vibration and impact during the winding process. A winding motor 62 is fixedly connected to one side of the support frame 61. The winding motor 62 is responsible for driving the winding operation and provides strong power support to ensure rapid winding of the yarn. A transmission rod 63 is fixedly connected to the drive end of the winding motor 62. A take-up drum 64 is mounted on the outside of the moving rod 63. The take-up drum 64 is a key component for actually collecting the yarn, ensuring that the yarn is wound up in a neat and orderly manner. A mounting plate 65 is mounted on one side of the support frame 61. The mounting plate 65 provides additional support and stability, which helps the normal operation of the take-up mechanism 6. An extension block 66 is fixedly connected to the bottom of the mounting plate 65. The extension block 66 increases the leverage of the take-up mechanism 6, making the take-up operation more flexible and efficient. A control rod 67 is slidably connected to one side of the extension block 66. The sliding connection design of the control rod 67 allows for... Adjustments are made during the winding process to accommodate different yarn specifications. Both ends of the control lever 67 are rotatably connected to connecting rods 68. The connecting rods 68 rotate and connect to achieve stable yarn winding. The other end of the connecting rod 68 is rotatably connected to a locking block 69. The design of the locking block 69 ensures that the yarn is reliably fixed during winding, preventing slack or knotting. A spring 610 is fixedly connected to one side of the control lever 67. The function of the spring 610 is to provide a restoring force to the control lever 67, ensuring that the equipment returns to its initial position when not in operation. The other end of the spring 610 is fixedly connected to one side of the winding drum 64. This connection can automatically release the tension after winding is completed, making the operation of the winding drum 64 easier and reducing human intervention. The outside of the locking block 69 engages with the inner wall of the support frame 61. This engagement design improves winding stability and ensures that the entire mechanism will not shift or deform during high-speed winding. One side of the transmission rod 63 is rotatably connected to the slot of the mounting plate 65. This rotatable connection allows the transmission rod 63 to rotate freely during operation, thereby effectively transmitting force without causing additional wear.

[0053] Specifically, the support frame 61 is fixed on the base 1, which enhances the overall rigidity of the equipment and effectively reduces vibration and impact. The winding motor 62 is responsible for driving the winding operation, and its power is transmitted to the winding drum 64 through the transmission rod 63 to achieve fast and neat yarn winding. The mounting plate 65 provides additional support for the winding mechanism 6 to ensure its normal operation. For easy disassembly, the extension block 66 is designed to slide and is connected to the control rod 67, so that the operator can easily adjust and disassemble it during replacement or maintenance. The two ends of the control rod 67 are connected to the locking block 69 through the connecting rod 68, which can effectively fix the yarn and prevent loosening or knotting during the winding process. The spring 610 on one side of the control rod 67 provides it with a reset force to ensure that the equipment automatically recovers when not in operation, which is convenient for disassembly and reassembly during maintenance.

[0054] Working principle: When the equipment is needed, the unwinding rod 52 with the material roll is installed in the slot of the mounting clamp 51. Then, multiple yarn bodies 7 are passed through the top of the adjusting roller 363, and then around the bottom of the limiting roller 364 to make the yarn bodies 7 taut. Finally, they pass through the groove of the rotating disk 382 from the bottom of the limiting roller 364, and then through the limiting sleeve 383 to the outside of the take-up drum 64.

[0055] When the moving motor 31 is started, the lead screw 32 is driven to rotate. The rotation of the lead screw 32 causes the thread block 37 to move, thereby causing the stranding assembly 38 to move, so that the stranded yarn can be evenly wound up. In this process, the stranding motor 381 is started to drive the rotating disk 382 and the limiting sleeve 383 to rotate, thereby stranding the yarn. When the lead screw 32 rotates, it also drives the rotating disk 33 to rotate. At this time, the rotation of the rotating disk 33 drives the rotating rod 34 to rotate. The rotation of the rotating rod 34 causes the cleaning plate 35 to be pushed, thereby causing the cleaning plate 35 to move back and forth. The movement of the cleaning plate 35 can clean the yarn body 7.

[0056] During this process, the hydraulic cylinder 361 is activated to move the moving block 362, which in turn moves the adjusting roller 363. This controls the tension of the yarn body 7, ensuring normal winding and cleaning. When the yarn body 7 is twisted, the extraction pump 42 is activated to draw water from the storage tank 41. The water then enters the connecting pipe 43 through the extraction pump 42 and is finally atomized and sprayed out from the nozzle 44, thereby generating a certain amount of humidity in the yarn body 7 and strengthening its toughness.

[0057] Finally, after being wound up by the take-up drum 64, the control rod 67 is pulled, which drives the connecting rod 68 to rotate. At this time, the connecting rod 68 will drive the locking block 69 to move. The movement of the locking block 69 can disengage from the inner wall of the extension block 66, so that the mounting plate 65 can slide out from one side of the support frame 61. At this time, the take-up drum 64 can be easily removed, and the disassembly is completed. Compared with the bolt disassembly in the prior art, it is more convenient.

[0058] Glass fiber warp yarns 71 and glass fiber weft yarns 72 are orthogonally stacked to form a basic structure. The inner layer of glass fiber yarns 73 intersects the glass fiber warp yarns 71 and glass fiber weft yarns 72 at an oblique angle to enhance the anisotropic mechanical properties of the yarns. The outer layer of glass fiber yarns 74 is also obliquely stacked with the inner layer of glass fiber yarns 73 to provide additional structural support. Multiple wetting agent layers 75 are disposed inside the yarn body 7 to improve the adhesion and wetting of the resin.
