Technical Field
[0001] This invention relates to the field of textile technology, and in particular to a lightweight, breathable, and UV-resistant warp-knitted elastic fabric. Background Technology
[0002] Currently, due to severe changes in the atmospheric environment, heat is a problem that everyone faces. Sunscreen clothing can offer some protection to the human body. Warp-knitted, weft-knitted, and woven fabrics are all used in the field of sunscreen fabrics. As we all know, woven fabrics are relatively stiff and not very breathable or elastic, while weft-knitted fabrics have better elasticity than woven fabrics.
[0003] However, weft-knitted fabrics lack breathability and crispness, while warp-knitted fabrics excel in both aspects. Therefore, warp-knitted sun-protective clothing is more commonly used in the market. Sun-protective clothing is primarily worn in hot weather with strong ultraviolet radiation. UV-resistant fabrics have inherent thickness and weight, which can affect the wearer's breathability and comfort. Achieving high-quality UV-resistant fabrics presents many technical challenges. In warp-knitted fabrics, achieving lightweight breathability, UV resistance, and good elasticity on a single fabric is precisely the problem we need to solve. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing UV-resistant fabrics, which have inherent thickness and weight, affecting the wearer's breathability and comfort. The invention proposes a lightweight, breathable, UV-resistant warp-knitted elastic fabric.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A lightweight, breathable, and UV-resistant warp-knitted elastic fabric includes a fabric body comprising an inner layer and an outer layer. The inner layer is a spandex elastic yarn weave layer made of spandex elastic material, and the outer layer is a UV-resistant weave layer made of UV-resistant chemical fiber filament material. The fabric body is formed by linking the spandex elastic yarn weave layer and the UV-resistant weave layer through loop interlacing. Both the UV-resistant weave layer and the spandex elastic yarn weave layer adopt a warp satin weave structure.
[0007] In one possible design, the spandex elastic material is made of spandex elastic yarn with a fineness of 15-30 denier.
[0008] In one possible design, the UV-resistant synthetic fiber filament material uses more than 75% UV-resistant yarn and less than 25% ordinary synthetic fiber filament, with the UV-resistant yarn having a fineness of 10-30 denier.
[0009] In one possible design, the fabric body is woven using a single-needle bed warp knitting machine (1), which is equipped with a first guide bar GB1, a second guide bar GB2, and a third guide bar GB3. Both the first guide bar GB1 and the second guide bar GB2 follow a closed warp satin structure in the same direction. The third guide bar GB3 is not used. The yarn padding numbers for both the first guide bar GB1 and the second guide bar GB2 are 0-1 / 2-1 / 3-2 / 1-2 / / . The yarn threading method for both the first guide bar GB1 and the second guide bar GB2 is full. The first guide bar GB1, the second guide bar GB2 and the third guide bar GB3 are in the same direction of warp knitting structure. The padding yarn number of the first guide bar GB1 is 0-1 / 2-1 / 3-2 / 1-2 / / , 1 pass 3 empty; the padding yarn number of the second guide bar GB2 is 0-1 / 2-1 / 3-2 / 1-2 / / , 1 empty 3 pass; the padding yarn number of the third guide bar GB3 is 0-1 / 2-1 / 3-2 / 1-2 / / , full pass. The needle density of the single needle bed warp knitting machine (1) is 24 to 44 needles per inch.
[0010] In one possible design, the finished weight of the fabric body is 90–120 g / m².
[0011] In one possible design, multiple yarn spools are evenly spaced on one side of the single-needle bed warp knitting machine, and a support plate is fixedly installed on the other side of the machine. A mounting bracket is fixedly installed on the support plate, and a movable hole is provided on the inner top wall of the mounting bracket. The single-needle bed warp knitting machine also includes:
[0012] The cutting mechanism is installed inside the mounting frame and is used to cut the woven fabric. The top of the cutting mechanism passes through the moving hole and extends to the top of the mounting frame. The cutting mechanism is connected to the top of the mounting frame.

[0014] The power mechanism is installed on the winding mechanism, and one side of the power mechanism is connected to the cutting mechanism.
[0015] In one possible design, the cutting mechanism includes a reciprocating screw rotatably connected within a mounting frame, a nut threaded onto the reciprocating screw, a movable plate fixedly mounted on one side of the nut, the reciprocating screw passing through the movable plate, the top of the movable plate passing through a movable hole and extending above the mounting frame, the movable plate slidably connected to the inner wall of the movable hole, a limit frame fixedly mounted on one side of the movable plate, a connecting plate slidably connected within the limit frame, one side of the connecting plate extending to the outer side of the limit frame, a movable rod fixedly mounted on the top of the connecting plate within the limit frame, the top end of the movable rod passing through the top inner wall of the limit frame and extending above the mounting frame, and a stop bar fixedly mounted on the top of one side of the movable rod above the mounting frame. A fixed plate is fixedly installed on the top of the mounting frame, and a corrugated plate is fixedly installed on one side of the fixed plate. A stop bar cooperates with the corrugated plate. A first tension spring is sleeved on the moving rod and located inside the limiting frame. The top and bottom ends of the first tension spring are fixedly connected to the top inner wall of the limiting frame and the bottom of the connecting plate, respectively. A transmission rod located outside the limiting frame is fixedly installed on the bottom of the connecting plate. An L-shaped base plate is fixedly installed on the bottom of the moving plate. A support cutter is fixedly installed on the L-shaped base plate. A strip ring is rotatably connected to one side of the L-shaped base plate. A stop shaft is fixedly installed on the bottom of one side of the transmission rod. The stop shaft passes through the strip ring and is connected to the strip ring for transmission. One end of the reciprocating screw extends to the outside of the mounting frame and is connected to the power mechanism.
[0016] In one possible design, the winding mechanism includes a fixed frame fixedly mounted on one side of a support plate. A drive shaft is rotatably connected through one inner wall of the fixed frame. The drive shaft is connected to a power mechanism at the location of the fixed frame. A first retaining cover is fixedly mounted on one end of the drive shaft inside the fixed frame. One end of the winding shaft extends into the first retaining cover and engages with the inner wall of the first retaining cover. A positioning component is connected through the other inner wall of the fixed frame. A second retaining cover is connected to one side of the positioning component inside the fixed frame. The other end of the winding shaft extends into the second retaining cover and engages with the inner wall of the second retaining cover. The positioning component is connected to one side of the fixed frame on the outer side of the fixed frame.
[0017] In one possible design, the positioning assembly includes a support frame fixedly mounted on one side of a fixed frame. A push plate is slidably sleeved on the support frame. A top rod is fixedly mounted on one side of the push plate. One end of the top rod extends into the fixed frame and is rotatably connected to one side of a second retaining cover. A compression spring located inside the support frame is sleeved on the top rod. The two ends of the compression spring are fixedly connected to one side of the fixed frame and one side of the push plate, respectively. A fixed plate is fixedly mounted on one side of the support frame. A support shaft is rotatably connected to the top of the fixed plate. A push rod is fixedly mounted on the support shaft. The push rod is in movable contact with the other side of the push plate. A handle is fixedly mounted at the top of the support shaft. An insertion rod is slidably connected through the handle. An insertion hole is opened on the fixed plate. The insertion rod passes through the insertion hole and is engaged with the insertion hole. A second tension spring is sleeved on the insertion rod. The top and bottom ends of the second tension spring are fixedly connected to the top of the insertion rod and the top of the handle, respectively.
[0018] In one possible design, the power mechanism includes a drive motor fixedly mounted on the inner wall of one side of the mounting frame. The output shaft of the drive motor extends to the outer side of the mounting frame and is fixedly mounted with a drive wheel. A first one-way bearing located on the outer side of the mounting frame is fixedly connected to the reciprocating screw. A second one-way bearing is fixedly mounted on the transmission shaft. Driven wheels are fitted on both the first and second one-way bearings. The drive wheel and the driven wheel are connected by the same transmission belt. Both the drive wheel and the driven wheel are synchronous pulleys, and the transmission belt is a synchronous belt.
[0019] In this invention, UV-resistant yarn and spandex elastic yarn are used. The UV-resistant yarn as the outer layer enables the fabric to have UV protection and sun protection effects, while the spandex elastic woven body as the inner layer can maintain the elasticity of the fabric. Combined with the use of UV-resistant yarn, wherein the UV-resistant yarn and spandex elastic yarn are formed by a warp satin structure to form the outer and inner layers, the fabric has the characteristics of being lightweight and breathable. Therefore, the fabric of this invention can achieve both lightweight and breathability while also providing UV protection and sun protection effects.
[0020] In this invention, a lightweight, breathable, and UV-resistant warp-knitted elastic fabric is provided. Through a cutting mechanism, the reciprocating screw can rotate after receiving power from the power mechanism. In conjunction with the transmission of the nut, it can drive the moving plate to move. As the moving plate moves, it can drive the moving rod to move synchronously. Under the tension of the first tension spring, the stop rod has a constant upward thrust. Thus, as the stop rod moves with the moving plate, it will contact different parts of the wave plate. Since the wave plate is undulating, the stop rod will also perform longitudinal reciprocating motion while moving laterally. This allows the moving rod to drive the connecting plate to perform longitudinal reciprocating motion within the limiting frame. Furthermore, as the connecting plate moves, the transmission of the transmission rod and the stop shaft can drive the strip ring to perform longitudinal reciprocating swing. The rotating cutter, moving with the strip ring, can, in conjunction with the supporting cutter, generate a shearing force on the fabric, thereby cutting the woven fabric.
[0021] In this invention, the lightweight, breathable, and UV-resistant warp-knitted elastic fabric, through the set winding mechanism, can rotate after the roller is clamped and positioned with the first and second clips respectively. At this time, the drive shaft can rotate after receiving the driving force of the power mechanism. Thus, under the transmission action of the first clip, the roller can be driven to rotate, thereby winding up the knitted fabric.
[0022] In this invention, a lightweight, breathable, and UV-resistant warp-knitted elastic fabric is provided. Through a power mechanism, the output shaft of a drive motor rotates clockwise, driving the transmission belt via the drive wheel. The two driven wheels also rotate. However, the first one-way bearing itself does not transmit power, and the reciprocating screw does not rotate. The second one-way bearing, receiving power from the corresponding driven wheel, drives the transmission shaft to rotate, which in turn drives the roll to rotate via the first retainer, allowing the woven fabric to be wound up. When the output shaft of the drive motor rotates in the opposite direction, causing the transmission belt to move in the opposite direction, the second one-way bearing stops transmitting power, while the first one-way bearing drives the reciprocating screw to rotate, enabling the fabric to be cut after it has been wound up.

After the roll 30 is engaged and positioned with the first cover 24 and the second cover 32 respectively, the drive shaft 23 can rotate after receiving the driving force of the power mechanism. Thus, under the transmission action of the first cover 24, the roll 30 can be driven to rotate, thereby enabling the winding of the woven fabric.

One end of the push rod 31 extends into the fixed frame 22 and is rotatably connected to one side of the second retaining cover 32. A compression spring 34 located inside the support frame 35 is sleeved on the push rod 31. The two ends of the compression spring 34 are fixedly connected to one side of the fixed frame 22 and one side of the push plate 33, respectively. A fixed plate 36 is fixedly mounted on one side of the support frame 35. A support shaft 37 is rotatably connected to the top of the fixed plate 36. A push rod 38 is fixedly mounted on the support shaft 37. The push rod 38 is in movable contact with the other side of the push plate 33. A handle rod is fixedly mounted at the top of the support shaft 37. An insert rod 39 is slidably connected through the handle rod. An insertion hole is opened on the fixed plate 36. The insert rod 39 passes through the insertion hole and is engaged with the insertion hole. A second retaining cover 32 is sleeved on the insert rod 39. The top and bottom ends of the tension spring 40 are fixedly connected to the top of the insertion rod 39 and the top of the handle rod, respectively. By rotating the handle rod, the support shaft 37 is rotated, which in turn drives the push rod 38 to move in an arc shape towards one side of the push plate 33. After the push rod 38 contacts the push plate 33, as the push rod 38 continues to move, it can push the push plate 33 closer to the fixing frame 22. This allows the push rod 31 to drive the second locking cover 32 closer to the scroll 30 until the scroll 30 is locked in place by the second locking cover 32. At this time, the insertion rod 39 moves with the handle rod to correspond to the insertion hole. After releasing the insertion rod 39, the second tension spring 40, which is under force, can pull the insertion rod 39 downward, so that the insertion rod 39 is locked in place with the insertion hole. This can achieve the positioning of the support shaft 37, so that the push rod 38 can stably limit the push plate 33.
[0093] Please continue reading. Figure 5 and Figure 11 The power mechanism includes a drive motor 29 fixedly mounted on the inner wall of one side of the fixed frame 22. The output shaft of the drive motor 29 extends to the outside of the fixed frame 22 and a drive pulley 27 is fixedly mounted thereon. A first one-way bearing 21 located on the outside of the mounting frame 4 is fixedly connected to the reciprocating screw 5. A second one-way bearing 25 is fixedly mounted on the transmission shaft 23. Driven pulleys 26 are mounted on both the first one-way bearing 21 and the second one-way bearing 25. The drive pulley 27 and the driven pulley 26 are connected by the same transmission belt 28. Both the drive pulley 27 and the driven pulley 26 are synchronous pulleys, and the transmission belt 28 is a synchronous belt. By starting the drive motor 29, its output shaft rotates clockwise, thereby enabling the drive pulley 27 to rotate clockwise. The drive belt 28 is driven to move, and the two driven pulleys 26 can also rotate. However, the first one-way bearing 21 itself will not drive, and the reciprocating screw 5 will not rotate. After receiving the drive from the corresponding driven pulley 26, the second one-way bearing 25 can drive the drive shaft 23 to rotate, which can drive the roll 30 to rotate through the first retainer 24 so as to roll up the woven fabric. When the output shaft of the drive motor 29 rotates in the opposite direction, it can drive the drive belt 28 to move in the opposite direction. At this time, the second one-way bearing 25 will not drive, and the first one-way bearing 21 will drive the reciprocating screw 5 to rotate so that the fabric can be cut after it is rolled up.
[0094] Working principle: After the fabric is woven by the single-needle bed warp knitting machine 1, one end of the roll 30 can be inserted into the first retaining cover 24. Then, the handle rod can be rotated to drive the support shaft 37 to rotate, which can drive the push rod 38 to move in an arc shape towards one side of the push plate 33. After the push rod 38 contacts the push plate 33, as the push rod 38 continues to move, it can push the push plate 33 closer to the fixing frame 22. This, through the push rod 31, can drive the second retaining cover 32 closer to the roll 30, until the roll 30 is clamped by the second retaining cover 32. At this time, the insertion rod 39 moves with the handle rod to correspond to the insertion hole. After that, after the insertion rod 39 is released, the second tension spring 40 under force can pull the insertion rod 39 downward, so that the insertion rod 39 is aligned with the insertion hole. The clamping process allows for the positioning of the support shaft 37, enabling the push rod 38 to stably limit the push plate 33. After positioning and installing the roll 30, one end of the woven fabric can be fixed to the roll 30. Then, the drive motor 29 can be started, causing its output shaft to rotate clockwise. This drives the transmission belt 28 via the drive wheel 27, and the two driven wheels 26 also rotate. However, the first one-way bearing 21 itself does not transmit power, and the reciprocating screw 5 does not rotate. The second one-way bearing 25, after receiving power from the corresponding driven wheel 26, drives the transmission shaft 23 to rotate. This, in turn, drives the roll 30 to rotate via the first clamping cover 24, allowing the woven fabric to be wound up. After completion, when the output shaft of the drive motor 29 is started to rotate in the reverse direction, it can drive the transmission belt 28 to move in the reverse direction. At this time, the second one-way bearing 25 will not transmit power, and the first one-way bearing 21 will drive the reciprocating screw 5 to rotate. At this time, under the transmission cooperation with the nut 6, it can drive the moving plate 9 to move. When the moving plate 9 moves, it can drive the moving rod 12 to move synchronously. Under the tension of the first tension spring 14, the stop rod 13 has a constant upward thrust. Thus, when the stop rod 13 moves with the moving plate 9, it will contact different parts of the wave plate 8. The wave plate 8 is undulating, so the stop rod 13 will also move longitudinally back and forth while moving laterally, and can pass through the moving rod. 12 drives the connecting plate 11 to reciprocate longitudinally within the limiting frame 10. While the connecting plate 11 moves, the transmission rod 15 and the stop shaft 16 work together to drive the strip ring 18 to reciprocate longitudinally. The rotating cutter 20, moving with the strip ring 18, works in conjunction with the supporting cutter 19 to apply shearing force to the fabric, thus cutting the woven fabric. After cutting, the insert rod 39 is pulled out of the insertion hole, and the handle is rotated in the opposite direction. The push plate 33 is then released from its limiting position, and the compressed spring 34, under stress, pushes the push plate 33 to move away from the fixing frame 22. This moves the second clip 32, releasing the clamp on the roll 30.The roll 30 containing the fabric can then be disassembled.
