Abstract
Description
Technical Field
[0001] This invention relates to the field of footwear material application technology, and in particular to a flexible, wear-resistant, high-tensile rope and its manufacturing process. Background Technology
[0002] The use of knob locking systems is very common in athletic shoes and children's shoes. A knob locking system is composed of a cord and a knob-type locking system for shoes. The two complement each other. In order to adapt to the mechanical force of the knob-type locking system for shoes, the cord in the system must have high tensile strength, high abrasion resistance and high durability. At the same time, it must also have a variety of cross-sections and shapes to meet the needs of knob-type locking systems for shoes of different sizes.
[0003] Currently, to meet the high-strength requirements of rotary locking systems for shoes, most products on the market use steel wire to enhance the physical properties of the cords. While this improves performance, in actual use, it has been found that the cords with the steel wire core have poor flexibility when locked, easily causing foot constriction and significantly reducing shoe comfort, leading to customer complaints. Ordinary fiber cords, on the other hand, have poor tensile strength. When woven from yarn, commonly used synthetic fibers often fail to meet the locking requirements of rotary locking systems. Furthermore, the fibers are prone to fibrillation during friction with the system, causing the cords to fray, pill, break, and even become difficult to operate.
[0004] Therefore, in response to the above problems, a flexible and wear-resistant high-tensile rope and its manufacturing process are proposed, which can meet the requirements of the rope properties of the shoe knob locking system, and solve the problem of insufficient flexibility of steel wire rope. Summary of the Invention
[0005] The purpose of this invention is to provide a flexible, wear-resistant, high-tensile rope and its manufacturing process to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a process for preparing a flexible, wear-resistant, high-tensile rope, comprising the following steps:
[0007] S1: Yarn selection: High-performance fiber filaments and PET fiber filaments are prepared by solution dyeing, and the high-performance fiber filaments are used as the core yarn of the rope, and the high-performance fiber filaments and PET fiber filaments are mixed and used as the outer yarn of the rope.
[0008] S2: Reinforcement treatment: High-performance fiber filaments and PET fiber filaments are coated with polytetrafluoroethylene using a coating machine, and then the coated filaments are sent into an oven for drying and curing.
[0009] S3: Ratio: Select a ratio of 1:2 to 1:3 for the amount of high-performance fiber filaments and PET fiber filaments used to braid ropes;
[0010] S4: Winding: The selected high-performance fiber filaments and PET fiber filaments are wound onto the spindles of the braiding machine in portions by a winding machine;
[0011] S5: Weaving: The high-performance fiber filaments used as the core yarn are fed to the rope braiding machine through the central spindle of the machine, and the high-performance fiber filaments used as the outer yarn and the PET fiber filaments are fed to the rope braiding machine through the disc spindle. The rope braiding machine adopts a three-dimensional multi-directional weaving method.
[0012] S6: Heat sealing treatment: Heat seal the ends of the woven rope in the above steps, and then wind and store the treated rope.
[0013] Preferably, the coating thickness of the high-performance fiber filament and PET fiber filament in S2 is 5 to 10 micrometers, and the drying and curing temperature in the oven is 60°C to 80°C for 1 to 2 hours.
[0014] Preferably, in S3, the high-performance fiber filaments are twisted before weaving as the core yarn, and the high-performance fiber filaments and PET fiber filaments in the outer wrapping yarn are woven in an independent bundle state.
[0015] Preferably, in S4, the winding rate of the high-performance fiber filament is 50 to 300 meters per minute, wherein the winding time of one spindle is 60 to 600 minutes, and the winding rate of the PET fiber filament is 100 to 300 meters per minute, wherein the winding time of one spindle is 60 to 300 minutes.
[0016] Preferably, in S5, the rotation speed of the central spindle is selected to be 30 to 150 rpm, the rotation speed of the disc spindle is selected to be 30 to 150 rpm, the stretching speed of the rope braiding machine is 5 to 20 m / min, and the rope braiding machine is a braiding machine with 12 to 24 spindles.
[0017] Preferably, in step S6, the rope is heat-sealed by a heat-sealing machine at a temperature of 120-180°C and a sealing time of 5-10 seconds.
[0018] Preferably, the method for preparing the high-performance fiber filament in S1 includes:
[0019] Step 1: Mixing and proportioning. Take ultra-high molecular weight polyethylene powder and decahydronaphthalene and mix them in a mass ratio of 1:8. The selected ultra-high molecular weight polyethylene powder has a molecular weight of 8 million to 9 million. Add antioxidant and paraffin oil and place it in a reactor for heating and stirring until uniform. The paraffin oil accounts for 1% of the total weight to prepare a uniform spinning solution A.
[0020] Step 2: Filtration and degassing. The spinning solution A is filtered through multiple stages. The filtered spinning solution is then placed in a vacuum environment with the vacuum degree controlled at -0.08 to -0.1 MPa. The degassing time is about 1-3 hours. During this process, bubbles will gradually escape from the solution, resulting in a bubble-free spinning solution B.
[0021] Step 3: Wet spinning. The spinning solution B is melted using a twin-screw extruder and then passed through a melt filter and spinneret to form nascent UHMWPE gel fibers. The nascent UHMWPE gel fibers after spinning are then treated in an extraction bath using an extractant.
[0022] Step 4: Post-treatment. The nascent ultra-high molecular weight polyethylene gel fibers are washed multiple times, with the water temperature controlled at 30-60℃ and each wash lasting 10-30 minutes. Through multiple washes, the solvents and additives on the surface of the gel fibers are removed. The washed fibers are then dried at a temperature of 80-150℃ to reduce the moisture content of the gel fibers to less than 1%.
[0023] Step 5: Tertiary stretching. The nascent ultra-high molecular weight polyethylene gel filaments are stretched using a stretching machine. First, a preliminary stretch of 2-5 times is performed, followed by a secondary stretch of 5-10 times under heating conditions, and then a tertiary stretch of 10-15 times under heating conditions.
[0024] Step Six: Filament Collection: The treated high-performance fiber filaments are collected using a filament collection device, wound into shape, and ready to enter the next process for rope and tape preparation.
[0025] Preferably, the heating temperature for heating and stirring in step one is 130℃-160℃, and the stirring speed is approximately 100-300 r / min.
[0026] Preferably, the multi-stage filtration in step two is as follows: first, a 5-10μm filter screen is used for preliminary filtration, and then a 1-3μm fine filter screen is used for secondary filtration.
[0027] In step three, the spinneret orifice count should be between 50 and 200.
[0028] Another object of the present invention is to provide a flexible and wear-resistant high-tensile rope, wherein the high-tensile rope is made by the above-mentioned manufacturing process of a flexible and wear-resistant high-tensile rope.
[0029] The technical effects and advantages of this invention are as follows:
[0030] (1) The present invention uses high-performance fiber filaments as the core yarn of the rope and PET fiber filaments as the outer yarn of the rope, so that the core yarn of the high-performance fiber filaments can be wrapped in the middle. Due to the high strength and toughness of the high-performance fiber filaments, the rope made therein maintains high tensile strength, which meets the mechanical force tension of the shoe knob locking system. Moreover, the rope is made of pure fiber, has strong bending performance, excellent flexibility, avoids foot chafing, and can meet the physical property requirements of the shoe knob locking system for the rope.
[0031] (2) This invention utilizes the three-dimensional multi-directional weaving method of high-performance fiber filaments and PET fiber filaments in the outer covering yarn, which facilitates the increase of the raised friction force on the outer wall of the rope. Furthermore, the high strength, heat resistance, chemical resistance and dimensional stability of the high-performance fiber filaments, and the excellent high strength and high abrasion resistance of the PET fiber filaments make it easy for the outer wall of the rope to rub against each other and prevent fraying. This makes the rope less likely to break when locked in the shoe knob-type locking system, resists daily wear and tear, and extends the service life of the rope. Moreover, the woven circular strip structure of the rope is highly compatible with the shoe knob-type locking system, and there is almost no resistance when the rope is threaded through the hole, making rope replacement convenient.
[0032] (3) The present invention uses solution-dyed high-performance fiber filaments and PET fiber filaments to produce high-tensile ropes with rich colors to meet various usage requirements. The ropes have excellent color fastness, and the high-performance fiber filaments and PET fiber filaments woven into the ropes are recyclable and environmentally friendly. The high-performance fiber filaments prepared have wear-resistant and corrosion-resistant properties, and the orientation and strength of the high-performance fiber filaments are improved, thus enhancing the strength of the ropes.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] Example 1
[0038] This invention provides, for example Figure 1-3 The process for manufacturing a flexible, wear-resistant, high-tensile rope is shown.
[0039] Methods for preparing high-performance fiber filaments include:
[0040] Step 1: Mixing and proportioning. Take ultra-high molecular weight polyethylene powder and decahydronaphthalene and mix them in a mass ratio of 1:8. The selected ultra-high molecular weight polyethylene powder has a molecular weight of 8 million to 9 million. Add antioxidant and paraffin oil and place it in a reactor. Heat and stir until uniform. The heating temperature for uniform stirring is 130℃ and the stirring speed is about 300 r / min. Paraffin oil accounts for 1% of the total weight to prepare a uniform spinning solution A.
[0041] Step 2: Filtration and degassing. The spinning solution A is subjected to multi-stage filtration, namely, firstly, preliminary filtration using a 5-10μm filter screen, and then secondary filtration using a 1-3μm fine filter screen; then the filtered spinning solution is placed in a vacuum environment with the vacuum degree controlled at -0.08MPa, and the degassing time is about 3 hours. During this process, bubbles will gradually escape from the solution, resulting in a bubble-free spinning solution B.
[0042] Step 3: Wet spinning. The spinning solution B is melted using a twin-screw extruder and then passed through a melt filter and a spinneret to form nascent ultra-high molecular weight polyethylene gel fibers. The spinneret has a mesh size of 50-200 holes. The nascent ultra-high molecular weight polyethylene gel fibers after spinning are then treated in an extraction bath using an extractant.
[0043] Step 4: Post-treatment. The nascent ultra-high molecular weight polyethylene gel fibers are washed multiple times, with the water temperature controlled at 30-60℃ and each wash lasting 10-30 minutes. Through multiple washes, the solvents and additives on the surface of the gel fibers are removed. The washed fibers are then dried at a temperature of 80-150℃ to reduce the moisture content of the gel fibers to less than 1%.
[0044] Step 5: Three-stage drawing. The nascent ultra-high molecular weight polyethylene gel filaments are drawn through a drawing machine. First, a preliminary drawing of 2-5 times is performed, followed by a secondary drawing of 5-10 times under a heating environment, and then a tertiary drawing of 10-15 times under a heating environment to obtain high-performance fiber filament products.
[0045] Step Six: Filament Collection: The treated high-performance fiber filaments are collected using a filament collection device, wound into shape, and ready to enter the next process for rope and tape preparation.
[0046] PET fiber filaments are produced using existing mature preparation methods to obtain finished PET fiber filaments.
[0047] A manufacturing process for a flexible, wear-resistant, high-tensile rope includes:
[0048] S1: Yarn selection: The high-performance fiber filament and PET fiber filament are both finished high-performance fiber filament and finished PET fiber filament prepared in the above preparation steps. The high-performance fiber filament and PET fiber filament are prepared by solution dyeing, so that the high-performance fiber filament and PET fiber filament can have a variety of color distribution, which improves the color richness of the prepared high-tensile rope. The high-performance fiber filament is used as the core yarn of the rope, and the high-performance fiber filament and PET fiber filament are mixed and used as the outer yarn of the rope.
[0049] S2: Reinforcement treatment: High-performance fiber filaments and PET fiber filaments are coated with polytetrafluoroethylene using a coating machine. The coating thickness is 5 micrometers. The speed of the coating machine should be matched with the coating thickness of the control rope. The coated filaments are then sent into an oven for drying and curing. The oven is dried and cured at a temperature of 80°C for 1 hour.
[0050] S3: Ratio: The ratio of high-performance fiber filaments and PET fiber filaments used to weave the rope is 1:2-1:3. The high-performance fiber filaments are selected as the core yarn with a fineness within the range of selection. The high-performance fiber filaments are twisted during the preparation process before weaving. The PET fiber filaments are existing mature PET fiber filament products. After preparation, the PET fiber filaments are twisted by a twisting machine. The high-performance fiber filaments and PET fiber filaments in the outer yarn are woven in an independent bundle state. The high-performance fiber filaments selected as the core yarn of the rope are filaments in a twisted state. The high-performance fiber filaments and PET fiber filaments selected as the outer yarn of the rope are also filaments in a twisted state.
[0051] S4: Winding: The selected high-performance fiber filaments and PET fiber filaments are wound onto the spindles of the braiding machine in portions through a winding machine. The winding rate of the high-performance fiber filaments is 100 meters / minute, and the winding time of one spindle is 200 minutes. The winding rate of the PET fiber filaments is 200 meters / minute, and the winding time of one spindle is 100 minutes.
[0052] S5: Weaving: The high-performance fiber filaments used as the core yarn are fed to the rope braiding machine through the central spindle of the machine. The rotation speed of the central spindle is selected as 100 rpm. The high-performance fiber filaments and PET fiber filaments used as the outer yarn are fed to the rope braiding machine through the disc spindle. The rotation speed of the disc spindle is selected as 100 rpm. The rope braiding machine adopts a three-dimensional multi-directional weaving method. The machine stretching speed of the rope braiding machine is 10 meters / minute. The rope braiding machine is a 24-spindle braiding machine.
[0053] S6: Heat Sealing Treatment: The ends of the woven rope from the above steps are heat-sealed using a heat-sealing machine at 180℃ for 5 seconds. The treated rope is then wound and stored. The woven rope needs to be stretched under tension before being wound into a cylinder. This requires six parallel rollers, each rotating at 10 meters per minute, to generate sufficient tension to better stretch the rope and achieve an optimal, tightly woven structure.
[0054] The tensile strength test results of the prepared high-tensile rope are as follows:
[0055]
[0056]
[0057] Example 2
[0058] like Figure 1 The process for manufacturing a flexible, wear-resistant, high-tensile rope is shown.
[0059] Methods for preparing high-performance fiber filaments include:
[0060] Step 1: Mixing and proportioning. Take ultra-high molecular weight polyethylene powder and decahydronaphthalene and mix them in a mass ratio of 1:8. The selected ultra-high molecular weight polyethylene powder has a molecular weight of 8 million to 9 million. Add paraffin oil and place it in a reactor. Heat and stir until uniform. The heating temperature for uniform stirring is 150°C and the stirring speed is about 180 r / min. Paraffin oil accounts for 1% of the total weight. Prepare a uniform spinning solution A.
[0061] Step 2: Filtration and degassing. The spinning solution A is subjected to multi-stage filtration. First, a 5-10μm filter screen is used for preliminary filtration to remove larger undissolved particles or impurities. Then, a 1-3μm fine filter screen is used for secondary filtration to ensure the purity of the spinning solution and prevent clogging of the spinneret. The filtered spinning solution is then placed in a vacuum environment with the vacuum level controlled at -0.1MPa for approximately 1 hour. During this process, bubbles will gradually escape from the solution, resulting in a bubble-free spinning solution B.
[0062] Step 3: Wet spinning. The spinning solution B is melted using a twin-screw extruder and then passed through a melt filter and a spinneret to form nascent UHMWPE gel fibers. The spinneret has 50-200 mesh holes. The nascent UHMWPE gel fibers are then treated in an extraction bath with an extractant. The extraction bath treatment involves placing an extractant in an extraction tank and allowing the nascent UHMWPE gel fibers to come into full contact with the extractant, which facilitates the removal of white oil from the fiber surface, resulting in UHMWPE gel fibers with little or no white oil.
[0063] Step 4: Post-processing. The nascent ultra-high molecular weight polyethylene gel fibers are washed multiple times at a water temperature of 60℃ for 20 minutes each time. Through multiple washes, solvents and additives on the surface of the gel fibers are removed. The washed fibers are then dried at 150℃ to reduce the moisture content of the gel fibers to less than 1%. Finally, heat setting is performed at 150℃ to improve the dimensional stability and performance of the fibers.
[0064] Step 5: Tertiary drawing. The nascent ultra-high molecular weight polyethylene gel filaments are drawn through a drawing machine. First, a preliminary drawing of 2-5 times is performed, followed by a secondary drawing of 5-10 times under a heated environment (e.g., 80-120℃), and then a tertiary drawing of 10-15 times under a heated environment. Through drawing, the molecular chains of the fiber filaments are straightened along the drawing direction, improving the strength and modulus of the fiber filaments, and obtaining high-performance fiber filament products.
[0065] Step Six: Filament Collection: The treated high-performance fiber filaments are collected using a filament collection device, wound into shape, and ready to enter the next process for rope and tape preparation.
[0066] PET fiber filaments are produced using existing mature preparation methods to obtain finished PET fiber filaments.

The high-performance fiber filament and PET fiber filament are prepared by solution dyeing, so that the high-performance fiber filament and PET fiber filament can have a variety of color distribution, which improves the color richness of the prepared high-tensile rope. The high-performance fiber filament is used as the core yarn of the rope, and the high-performance fiber filament and PET fiber filament are mixed and used as the outer yarn of the rope.
[0069] S2: Reinforcement treatment: High-performance fiber filaments and PET fiber filaments are coated with polytetrafluoroethylene using a coating machine. The coating thickness is 5 micrometers. The speed of the coating machine should be matched with the coating thickness of the control rope. The coated filaments are then sent into an oven for drying and curing. The oven is dried and cured at a temperature of 70°C for 1.5 hours.
[0070] S3: Ratio: The ratio of high-performance fiber filaments and PET fiber filaments used to weave the rope is 1:2-1:3. The high-performance fiber filaments are selected as the core yarn with a fineness within the range of selection. The high-performance fiber filaments are twisted during the preparation process before weaving. The PET fiber filaments are existing mature PET fiber filament products. After preparation, the PET fiber filaments are twisted by a twisting machine. The high-performance fiber filaments and PET fiber filaments in the outer yarn are woven in an independent bundle state. The high-performance fiber filaments selected as the core yarn of the rope are filaments in a twisted state. The high-performance fiber filaments and PET fiber filaments selected as the outer yarn of the rope are also filaments in a twisted state.
[0071] S4: Winding: The selected high-performance fiber filaments and PET fiber filaments are wound onto the spindles of the braiding machine in portions through a winding machine. The winding rate of the high-performance fiber filaments is 300 meters / minute, and the winding time of one spindle is 60 minutes. The winding rate of the PET fiber filaments is 300 meters / minute, and the winding time of one spindle is 60 minutes.
[0072] S5: Weaving: The high-performance fiber filaments used as the core yarn are fed to the rope braiding machine through the central spindle of the machine. The rotation speed of the central spindle is selected as 120 rpm. The high-performance fiber filaments and PET fiber filaments used as the outer yarn are fed to the rope braiding machine through the disc spindle. The rotation speed of the disc spindle is selected as 120 rpm. The rope braiding machine adopts a three-dimensional multi-directional weaving method. The machine stretching speed of the rope braiding machine is 15 m / min. The rope braiding machine is a 24-spindle braiding machine.
[0073] S6: Heat Sealing: The ends of the woven rope from the above steps are heat-sealed using a heat-sealing machine at 120℃ for 10 seconds. The treated rope is then wound and stored. The woven rope needs to be stretched under tension before being wound into a cylinder. This requires six parallel rollers, each rotating at 10 meters per minute, to generate sufficient tension to better stretch the rope and achieve an optimal, tightly woven structure.
