Description

Technical Field

[0001] This invention relates to a method for weaving trademark tape, and more particularly to a method for weaving a special polyester trademark tape. Background Technology

[0002] Trademark tape is a small piece of fabric used as a product identifier. It is continuously woven into a strip during production and then cut into specified sizes according to requirements. Each small piece contains the brand name, weaving factory, country name, and specifications.

[0003] Label tapes typically use high-count bleached or colored cotton yarn, raw silk, polyester yarn, nylon yarn, rayon, elastic nylon yarn, and metallic threads as warp and weft yarns, woven in whole rolls on wide-width machines. Synthetic fiber products, after being woven on a loom, also require thermal cutting. Thermal cutting increases energy consumption, and if the material blend ratio is improper (e.g., too high a cotton content), or if the cutting temperature and speed are not accurately controlled, the edges are prone to fraying and fraying. Furthermore, the cut edges become harder than the main fabric due to melting, creating burrs that can cause scratches and injuries when worn close to the skin, affecting comfort.

[0004] When using the edge label method, the edge warp yarns not only have to withstand the opening motion, but also the additional friction of the edge locking mechanism. Therefore, during high-speed reciprocating motion, the edge warp yarns are very prone to fuzzing and breaking, causing machine downtime and reducing production speed. Summary of the Invention

[0005] The purpose of this invention is to provide a method for weaving special polyester trademark tape. This invention features no need for heat slitting, reduced edge fray, and improved weaving efficiency and comfort.

[0006] The technical solution of the present invention: a method for weaving polyester special trademark tape, comprising the following steps:

[0007] S1. Select polyester triangle-shaped yarn as the warp yarn;

[0008] S2. The warp yarns are processed into weaving yarn and selvage yarn through warping, and then sized and dried so that the strength and abrasion resistance of the selvage yarn are greater than those of the weaving yarn.

[0009] S3. The dried weaving yarn and the selvage yarn are passed through a loom, and fully dull polyester yarn is introduced as the weft yarn for shuttleless weaving and selvage to obtain the raw strip;

[0010] S4. Rinse and desizing the raw strip, dry it, and roll it into a roll to obtain a trademark strip with a contrast between matte and glossy finish.

[0011] In the aforementioned method for weaving polyester special trademark tape, in step S3, the shuttleless weaving edge locking is achieved by the weft needles introducing the upper and lower weft yarns towards the weft opening through a swinging motion, forming a tight fabric structure. When the weft needles complete the weft insertion and withdraw, the edge locking needles immediately move, hooking the edge locking yarns and performing reciprocating hooking, looping, and unlooping actions, forming a continuous loop chain at the edge of the fabric, effectively fixing the ends of the double-layer weft yarns and preventing them from unraveling.

[0012] In the aforementioned method for weaving polyester special trademark tape, in step S2, the sizing rate of the selvage yarn is greater than the sizing rate of the weaving yarn.

[0013] In the aforementioned method for weaving polyester special trademark tape, the sizing process in step S2 is carried out using sizing equipment. The sizing equipment includes a sizing tank, in which a front immersion roller, a front pressing roller group, a rear immersion roller, and a rear pressing roller group are arranged sequentially. The working surface of the front pressing roller group is located inside the sizing liquid, while the working surface of the rear pressing roller group is located outside the sizing liquid. The pressure of the front pressing roller group is lower than that of the rear pressing roller group. The front pressing roller group includes an upper front pressing roller and a lower front pressing roller. The front immersion roller and the rear immersion roller rotate in the same direction, while the lower front pressing roller rotates in the opposite direction. A first stirring wheel is provided at one end of the front immersion roller, a second stirring wheel is provided at the end of the rear immersion roller opposite to the front immersion roller, and a third stirring wheel is provided at both ends of the lower front pressing roller.

[0014] In the aforementioned method for weaving polyester special trademark tape, a pressure roller is provided above the upper front pressure roller. The pressure roller is rotatably connected to the sizing tank and driven by a rotating motor. The surface of the pressure roller is provided with several rows of protruding sections, which are composed of several rollers that are rolled and connected to the surface of the pressure roller. Both ends of the upper front pressure roller are slidably connected to the sizing tank through sliding plates. Both ends of the upper front pressure roller are rotatably connected to the sliding plates through bearings. The sliding plates are provided with tension springs. The bottom of the tension springs is connected to the sliding plates, and the top of the tension springs is provided with a hydraulic cylinder for driving the upper front pressure roller.

[0015] In the aforementioned method for weaving polyester special trademark tape, the rear pressure roller group includes an upper rear pressure roller and a lower rear pressure roller. The upper rear pressure roller includes a mandrel. A rubber layer is sleeved on the outside of the mandrel. Several heating channels are provided inside the rubber layer. A heat insulation layer is provided on the inner side of the rubber layer. Several annular airbags that abut against the heat insulation layer are provided between the mandrel and the heat insulation layer along the length direction. An airflow channel communicating with the annular airbags is provided on the mandrel.

[0016] In the aforementioned method for weaving polyester special trademark tape, during the calendering process in step S4, a calendering machine is used for calendering. A seam detector is provided on the fabric feeding side of the calendering machine. The seam detector is electrically connected to the hydraulic station via a PLC controller, and the hydraulic station is connected to the calendering machine. The calendering machine includes a machine body, on which an upper roller, a middle roller, and a lower roller are sequentially arranged. The upper roller and the lower roller are slidably connected to the machine body via sliders. The middle roller is fixed to the machine body. A first hydraulic cylinder that pushes the upper roller downward is provided on the sliders on both sides of the upper roller, and a second hydraulic cylinder that pushes the lower roller upward is provided on the sliders on both sides of the lower roller. Compression springs are also provided on the sliders on both sides of the upper roller. The top of the compression springs is fixedly connected to the slider of the upper roller, and the bottom of the compression springs is fixedly connected to the machine body.

[0017] In the aforementioned method for weaving polyester special trademark tape, the upper roller is a spindle-shaped roller, which includes a core roller and a nylon sleeve. A first end airbag, a middle airbag, and a second end airbag are sequentially arranged along the axial direction between the core roller and the nylon sleeve, which abut against the nylon sleeve. The core shaft is provided with gas distribution channels that are respectively connected to the first end airbag, the middle airbag, and the second end airbag. The gas distribution channels are provided with airflow valves that respectively control the air pressure of the first end airbag, the middle airbag, and the second end airbag.

[0018] In the aforementioned method for weaving polyester special trademark tape, flattening rollers are provided on both the feed side of the lower roller and the output side of the upper roller. The trademark tape passes under the flattening rollers, and a mounting frame is provided above the flattening rollers. Movable frames are provided at both ends of the flattening rollers, and tension springs are provided between the mounting frame and the movable frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This invention uses polyester triangular profiled yarn as warp and fully dull polyester filament as weft, significantly reducing pilling and fuzzing, resulting in high gloss and a soft hand feel. It produces a unique visual effect of contrasting matte and gloss, enhancing the three-dimensionality of the pattern. Furthermore, the weaving yarn and the edge yarn are treated separately, ensuring that the edge yarn has greater strength and abrasion resistance than the weaving yarn. This avoids pilling, abrasion, and breakage during weaving, improving weavability and efficiency, while also increasing the edge strength of the label tape, thus preventing fraying and unraveling, and extending the overall lifespan of the fabric.

[0021] This invention can directly weave according to the yarn count of the finished product specifications, with the edges naturally locked by the weft yarn, making it less prone to fraying or unraveling. It also eliminates the need for subsequent heat slitting, saving energy and avoiding hard edges and burrs during label tape slitting, thus preventing scratches and injuries that may occur when the cut edges come into contact with the skin, and improving comfort.

[0022] By using specific sizing equipment to fully and evenly sizing the warp yarns, and ensuring that the sizing rate of the selvedge yarn is greater than that of the weaving yarn, the weaving performance of the warp yarns (especially the selvedge yarn) is improved, the breakage and fraying are reduced, and the scrap rate is lowered.

[0023] The strip is calendered using a specific calendering machine to maintain uniform softness, luster, and fiber tightness, making it less prone to knots or wrinkles. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0035] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a hinged connection, a rotatable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] Example:

[0037] The weaving method for polyester special trademark tape includes the following steps:

[0038] S1. Select polyester triangle-shaped yarn as the warp yarn;

[0039] S2. The warp yarns are processed into weaving yarn and selvage yarn through warping, and then sized and dried so that the strength and abrasion resistance of the selvage yarn are greater than those of the weaving yarn.

[0040] S3. The dried weaving yarn and the selvage yarn are passed through a loom, and fully dull polyester yarn is introduced as the weft yarn for shuttleless weaving and selvage to obtain the raw strip;

[0041] S4. Rinse and desizing the raw strip, dry it, and roll it into a roll to obtain a trademark strip with a contrast between matte and glossy finish.

[0042] This invention uses polyester triangular profiled yarn as warp and fully matte polyester filament as weft, significantly reducing pilling and fuzzing. It boasts high gloss and a soft hand feel, creating a unique visual effect of matte and gloss contrast, enhancing the three-dimensionality of the pattern. It can be woven directly according to the yarn count of the finished product, with the edges naturally sealed by the weft yarn, eliminating the need for subsequent heat slitting. This saves energy and avoids burrs on the edges during label tape slitting, thus preventing potential scratches and injuries from burrs contacting the skin.

[0043] Sizing is performed during the weaving process, with the sizing rate of the selvedge yarn being greater than that of the weaving yarn. This enhances the abrasion resistance, cohesion, and weavability of the selvedge yarn during the weaving process, preventing wear and breakage during weaving.

[0044] In step S2, the warping machine used has a warping beam size of 400*450 and a selvedge beam size of 200*300. Different yarn end counts are selected based on the different specifications of the label tape.

[0045] In step S3, the shuttleless weaving edge binding is achieved by the weft needles using a swaying motion to introduce the upper and lower weft yarns towards the weft edge, forming a tight fabric structure. When the weft needles finish beating and withdraw, the edge binding needles immediately move, hooking the edge binding yarns and performing a reciprocating hooking, looping, and unlooping motion, forming a continuous loop chain at the edge of the fabric. This effectively fixes the ends of the weft yarns, forming a double-layered edge binding structure. The structure is tight, not easy to spring back, and the structure is more stable, preventing unraveling.

[0046] In step S2, the sizing process is carried out using sizing equipment, which includes a sizing tank 1. The sizing tank 1 is sequentially equipped with a front immersion roller 21, a front pressing roller group, a rear immersion roller 24, and a rear pressing roller group. The working surface of the front pressing roller group is located inside the sizing liquid, while the working surface of the rear pressing roller group is located outside the sizing liquid. The pressure of the front pressing roller group is lower than that of the rear pressing roller group. The front pressing roller group includes an upper front pressing roller 22 and a lower front pressing roller 23. The front immersion roller 21 and the rear immersion roller 24 rotate in the same direction, while the lower front pressing roller 23 rotates in the opposite direction to the front immersion roller 21. One end of the front immersion roller 21 is equipped with a first stirring wheel 211, and the rear immersion roller 24 is equipped with a second stirring wheel 241 at the end opposite to the front immersion roller 21. Both ends of the lower front pressing roller 23 are equipped with third stirring wheels 231.

[0047] The warp yarns pass sequentially through the front immersion roller 21, the front pressure roller group, the rear immersion roller 24, and the rear pressure roller group within the sizing tank 1. The warp yarns are immersed in the sizing solution at the front immersion roller 21, the front pressure roller group, and the rear immersion roller 24, but are exposed at the rear pressure roller group. This achieves a multi-immersion, multi-pressure sizing method, extending the sizing path and allowing the sizing solution to fully and efficiently penetrate the irregularly shaped warp yarns, improving penetration and forming a protective film on the warp yarn surface at the final rear pressure roller group. The pressure of the front pressure roller group is lower than that of the rear pressure roller group. The pressure of the sizing roller group is relatively low, and its main function is to initially squeeze the yarn to accelerate the wetting and adsorption of the sizing liquid, so that the sizing liquid can fully penetrate between the shaped fibers. The low pressure allows more sizing liquid to enter the yarn interior, laying the foundation for the sizing and penetration of the subsequent immersion roller 24. The subsequent pressure sizing roller group uses higher pressure, which can squeeze off the excess sizing liquid on the yarn surface, control the thickness and sizing rate of the sizing liquid on the yarn surface, and make the remaining sizing liquid form a tough, smooth, and wear-resistant complete sizing film on the yarn surface, avoiding the sizing film from being too thick and causing brittle breakage.

[0048] The front immersion roller 21 and the rear immersion roller 24 rotate in the same direction, while the lower front pressure roller 23 rotates in the opposite direction to the front immersion roller 21. This results in the first stirring wheel 211 and the second stirring wheel 241, which are respectively set on the front immersion roller 21 and the rear immersion roller 24, rotating in the same direction. The third stirring wheel 231 on the lower front pressure roller 23 rotates in the opposite direction to the adjacent first stirring wheel 211 and second stirring wheel 241. This generates an active and continuous fluid shear force with a large agitation range and a high degree of turbulence, which can better push the sizing liquid into the yarn. The uniformity of sizing is more uniform than that of mechanical extrusion sizing.

[0049] Above the upper front pressure roller 22, a pressure roller 3 is provided. The pressure roller 3 is rotatably connected to the slurry tank 1 and is driven by a rotating motor 32. The surface of the pressure roller 3 is provided with several rows of protruding sections, which are composed of several rollers 31 that are rolled and connected to the surface of the pressure roller 3. Both ends of the upper front pressure roller 22 are slidably connected to the slurry tank 1 through sliding plates 221. Both ends of the upper front pressure roller 22 are rotatably connected to the sliding plates 221 through bearings. The sliding plates 221 are provided with tension spring members 222. The bottom of the tension spring members 222 is connected to the sliding plates 221, and the top of the tension spring members 222 is provided with a hydraulic cylinder 223 for driving the upper front pressure roller 22.

[0050] Under the action of hydraulic cylinder 223, the upper front pressure roller 22 applies a fixed base pressure to the lower front pressure roller 23 for sizing. A pressure roller 3 is installed above the upper front pressure roller 22, driven by a rotary motor 32. When the roller rotates to the point where the protruding section contacts the pressure roller 3, a downward force is applied, stretching the tension spring 222 and causing the pressure roller 3 to move downwards to apply pressure. When the roller rotates to the point where the protruding section no longer contacts the pressure roller 3, the pressure roller 3 moves upwards under the restoring action of the tension spring 222, returning to its original position to depressurize, thus... On top of the stable base pressure of the upper pressure roller 22, a high-frequency, small-amplitude pressure fluctuation is superimposed to achieve dynamic changes in total pressure. This continuously disrupts the surface tension between the sizing solution and the fiber interface, and promotes micro-flow of the sizing solution, allowing it to more effectively penetrate the fine grooves of the polyester profiled fibers. During the decompression stage, the compacted yarn structure will slightly rebound, and the gaps between fibers will instantly increase, forming a slight negative pressure that draws in more sizing solution. The subsequent pressurization stage further compresses the drawn-in sizing solution, penetrating deeper into the fiber bundle and stabilizing the amount of sizing solution adhering to the fiber. Furthermore, the large specific surface area of ​​polyester profiled fibers makes it easy to trap air during sizing. The intermittent pressure changes help disrupt the stable state of microbubbles in the sizing solution, causing them to be released from the yarn interior, reducing sizing defects and improving the uniformity of sizing.

[0051] The rear pressure roller assembly includes an upper rear pressure roller 25 and a lower rear pressure roller 26. The upper rear pressure roller 25 includes a mandrel 251. A rubber layer 252 is sleeved on the outside of the mandrel 251. Several heating channels 253 are provided inside the rubber layer 252. A heat insulation layer 254 is provided on the inner side of the rubber layer 252. Several annular airbags 255 that abut against the heat insulation layer 254 are provided between the mandrel 251 and the heat insulation layer 254 along the length direction. An airflow channel 256 communicating with the annular airbags 255 is provided on the mandrel 251. During sizing, fine-tuning the air pressure of the annular airbag 255 allows for more precise adjustment of the sizing pressure. This ensures the pressure is greater than that of the front sizing roller group while avoiding excessive pressure that could affect the irregular structure of the warp yarns. Furthermore, adjusting the air pressure of the annular airbags 255 at different positions allows for adjustment of the sizing pressure of the yarns at different locations on the upper and lower pressure rollers 25. This ensures that the sizing pressure of the selvedge yarn is lower than that of the woven yarn, resulting in a higher sizing rate for the selvedge yarn compared to the woven yarn. A heating channel 253 is installed within the rubber layer 252, through which heated oil or water can be introduced to increase the sizing temperature of the rear sizing roller group. This helps the sizing liquid on the yarn surface penetrate into the yarn's interior, ensuring the sizing liquid spreads evenly on the yarn surface, forming a continuous, smooth, and elastic sizing film. It also reduces the yarn's moisture content, lessening the pressure and energy consumption of subsequent drying operations.

[0052] In step S4, during the calendering process, a calendering machine 5 is used for calendering. A seam detector 41 is installed on the fabric feed side of the calendering machine 5. The seam detector 41 is electrically connected to a hydraulic station 43 via a PLC controller 42, and the hydraulic station 43 is connected to the calendering machine 5. The calendering machine 5 includes a machine body 51, on which an upper roller 52, a middle roller 53, and a lower roller 54 are sequentially mounted. The upper roller 52 and the lower roller 54 are slidably connected to the machine body 51 via a slider 541. Roller 53 is fixed on machine body 51. The sliders 541 on both sides of upper roller 52 are equipped with first hydraulic cylinders 55 that push upper roller 52 downward. The sliders 541 on both sides of lower roller 54 are equipped with second hydraulic cylinders 56 that push lower roller 54 upward. Compression springs 57 are also provided on the sliders 541 on both sides of upper roller 52. The top of compression springs 57 is fixedly connected to the sliders 541 of upper roller 52, and the bottom of compression springs 57 is fixedly connected to machine body 51.

[0053] When the seam head detector 41 detects a seam head on the trademark tape, the PLC controller 42 controls the calender 5 to depressurize via the hydraulic station 43, increasing the gap between the rollers and allowing the seam head to pass through the gap, thus avoiding damage to the calender rollers. In the depressurized state, the upper roller 52 is pressed against the middle roller 53 by gravity, and the compression spring 57 overcomes the gravity of the upper roller 52 to achieve a slight upward lift, making the upper roller 52 suspended. For thin seam heads, their own thickness is enough to open the gap between the upper roller 52 and the middle roller 53, allowing them to pass through smoothly, avoiding the phenomenon that the upper roller 52 cannot be opened due to excessive weight or thin seam head.

[0054] The upper roller 52 is a spindle-shaped roller, comprising a core roller 521 and a nylon sleeve 522. A first end airbag 523, a middle airbag 524, and a second end airbag 525 are sequentially arranged along the axial direction between the core roller 521 and the nylon sleeve 522, abutting against the nylon sleeve 522. The mandrel 251 is provided with gas distribution channels 526 communicating with the first end airbag 523, the middle airbag 524, and the second end airbag 525 respectively. The gas distribution channels 526 are provided with airflow valves 527 that control the air pressure of the first end airbag 523, the middle airbag 524, and the second end airbag 525 respectively. By setting the upper roller 52 to a spindle shape, when pressure is applied, it can offset the deformation caused by high pressure at both ends and low pressure in the middle, ensuring that the pressure on the main stress surface in the middle of the label tape is completely uniform, guaranteeing the uniform softness, gloss, and fiber tightness of the label tape body. Furthermore, a first end airbag 523, a middle airbag 524, and a second end airbag 525 are provided inside the upper roller 52. The air pressure of the first end airbag 523, the middle airbag 524, and the second end airbag 525 is adjustable, thereby fine-tuning the pressure of the upper roller 52 on different parts of the trademark tape according to different situations. For example, if the edge yarn is not pressed flat, the edge calendering pressure is increased; if the edge of the trademark tape is hardened and flattened, or the width increases, the shaping calendering pressure on the edge part of the trademark tape is reduced to prevent edge damage and calendering, maintain its soft edge, and avoid the trademark tape from knotting or edge wrinkling. It can adapt to different trademark tape weaving types without replacing the roller. Moreover, when the trademark tape passes through the seam end, by reducing the air pressure of the airbags, the seam end can more easily pass through the gap between the upper roller 52 and the middle roller 53, avoiding damage to the rollers.

[0055] Both the feed side of the lower roller 54 and the output side of the upper roller 52 are equipped with flattening rollers 61. The trademark strip passes under the flattening roller 61. A mounting frame 62 is provided above the flattening roller 61, and movable frames 63 are provided at both ends of the flattening roller 61. A tension spring 64 is provided between the mounting frame 62 and the movable frame 63. When the pressure of the calender 5 is depressurized, the trademark strip may have slight tension unevenness or small wrinkles, which the flattening roller 61 can smooth out. Furthermore, the tension spring 64 can adapt to the different tensions of the trademark strip during normal calendering and depressurization, so that the flattening roller 61 always maintains effective contact with the trademark strip and plays an effective flattening role.
