Abstract
Description
A waterproof coating composite equipment and process for polyester fabric Technical Field
[0001] This invention relates to the field of polyester fabric technology, specifically to a waterproof coating composite equipment and process for polyester fabrics. Background Technology
[0002] Polyester fabric is a synthetic fabric made of polyester fiber. Waterproof coating lamination of polyester fabric is a functional processing technology that combines coating film formation and layered lamination. The core technology uses two paths: direct coating without a film or thermal fusion lamination with a film, to give polyester waterproof properties. It can also be layered with properties such as breathability, abrasion resistance, and windproofing as needed, and is widely used in outdoor clothing, tents, protective clothing, bags, and other fields. However, existing polyester fabric waterproof coating lamination equipment has certain drawbacks. The polyester base fabric and waterproof breathable membrane are laminated together with the first and second fixed rollers. The equipment relies solely on the traction force of the lamination roller to move the fabric forward. The section between the polyester base fabric and the waterproof breathable membrane from the unwinding roller to the lamination roller is a free conveying section without real-time tensioning and correction devices. The fabric cannot accurately enter between the two fixed rollers, and vibration easily occurs when the fabric enters this section, leading to wrinkles that cannot be recovered after being directly pressed together. This ultimately results in wrinkles and indentations on the finished fabric, affecting its feel. Summary of the Invention

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.
[0019] Example 1: As shown in Figures 1-6, a waterproof coating laminating device for polyester fabric includes a hot melt coating laminating machine body 1. The hot melt coating laminating machine body 1 is used to laminate a waterproof coating or a waterproof and breathable membrane onto polyester fabric. Side plates 2 are installed on both sides of the hot melt coating laminating machine body 1. A first fixed roller 3 and a second fixed roller 4 are mounted between the two side plates 2. The polyester base fabric and the waterproof and breathable membrane rotate on the two rollers, thereby conveying the polyester base fabric and the waterproof and breathable membrane between the first fixed roller 3 and the second fixed roller 4. The first fixed roller 3 and the second fixed roller 4 can laminate the polyester base fabric and the waterproof and breathable membrane together. The laminated polyester base fabric and the waterproof and breathable membrane are conveyed to a third roller, where they are wound onto the third roller. A fabric tensioning assembly 5 is provided between the two side plates 2 and above the first fixed roller 3 and the second fixed roller 4. The fabric tensioning assembly 5 includes a first fixing strip 51, which is installed between the two side plates 2. The two ends of the side plate 2 are bolted between the two side plates 2 of the hot melt coating laminating machine body 1. The two ends of the first fixing strip 51 are welded with two first side strips 52 and two second side strips 56. A guide plate 55 is erected between the two first side strips 52 and the two second side strips 56. The two corners of the top of the guide plate 55 are movably connected to the two second side strips 56 respectively. The middle of the two sides of the guide plate 55 are movably connected to the two first side strips 52 respectively. The guide plate 55 is erected between the two second side strips 56 and the two first side strips 52, so that the guide plate 55 is erected on the upper surface of the first fixed roller 3. The waterproof and breathable membrane can slide along the upper surface of the guide plate 55. The waterproof and breathable membrane and the polyester base fabric can pass through the gap between the first fixed roller 3 and the second fixed roller 4. The first fixed roller 3 and the second fixed roller 4 can laminate the polyester base fabric and the waterproof and breathable membrane together. The guide plate 55 is used to guide the fabric to the gap between the first fixed roller 3 and the second fixed roller 4 after it is stretched.
[0020] Please refer to Figures 4-6. Each of the two first side strips 52 has a mating hole inside, and a first gear 53 is rotatably connected inside the mating hole. The first gear 53 can rotate relative to the mating hole inside the first side strip 52. A first connecting hole 58 is provided on the end face of the first gear 53. A first connecting pin 57 is integrally provided at the middle of both sides of the guide plate 55. The two first connecting pins 57 are rotatably connected to the first connecting holes 58 respectively. The rotation of the first gear 53 drives the first connecting pins 57 inside the first connecting holes 58 to rotate, thereby causing the guide plate 55 to swing back and forth. The guide plate 55 is arc-shaped. Second gears 54 are fixedly installed at both ends of the first fixed roller 3. The two second gears 54 mesh with the two first gears 53. The meshing of the first gears 53 and the second gears 54 drives the first gear 53 to rotate, allowing the waterproof and breathable membrane to be guided along the guide plate 55 between the first fixed roller 3 and the second fixed roller 4.
[0021] Please refer to Figures 5 and 6. The axis of the first connecting pin 57 is eccentrically arranged with the axis of the first gear 53. The eccentric arrangement of the axis of the first connecting pin 57 and the axis of the first gear 53 is used to swing the guide plate 55 back and forth. Due to the eccentric arrangement of the axis of the first connecting pin 57 and the axis of the first gear 53, the guide plate 55 swings up and down, and the end of the guide plate 55 intermittently contacts the outer circle of the second fixed roller 4. The guide plate 55 is used to tightly bond the two layers of fabric together. The end of the waterproof and breathable membrane at the end of the guide plate 55 can be pressed against the outer circle of the second fixed roller 4, so that the polyester base fabric and the waterproof and breathable membrane are adhered together.
[0022] Please refer to Figures 4 and 6. Each of the two second side strips 56 has a second connecting hole 510 at its bottom end. A second connecting pin 59 is welded to each of the two corners at the top of the guide plate 55. The second connecting pin 59 is located inside the second connecting hole 510. Because the first connecting pin 57 of the guide plate 55 rotates with the first connecting hole 58 of the first gear 53, the second connecting pin 59 of the guide plate 55 swings. The inner diameter of the second connecting hole 510 is larger than the diameter of the second connecting pin 59. The diameter of the second connecting pin 59 and the inner diameter of the second connecting hole 510 are used to prevent the guide plate 55 from breaking. The swinging of the first connecting pin 57 causes the second connecting pin 59 of the guide plate 55 to swing with the inside of the second connecting hole 510, preventing interference with the guide plate 55 and damage to the guide plate 55.
[0023] Please refer to Figures 3 and 7-9. A fabric pressing assembly 6 is provided between the two side plates 2 and below the first fixed roller 3 and the second fixed roller 4. The fabric pressing assembly 6 includes a second fixing strip 61, which is installed between the two side plates 2 and fixed between them by bolts. The second fixing strip 61 is installed between the first fixed roller 3 and the second fixed roller 4. A third side plate 62 is welded to both ends of the second fixing strip 61. A fixing pin 65 is rotatably connected inside the two third side plates 62. A ring is provided around the outside of the fixing pin 65. Both ends of the pressing strip 66 and the fixing pin 65 are provided with a third gear 63. The two third gears 63 mesh with the two second gears 54 respectively. The rotation of the second gears 54 can rotate the third gears 63, thereby driving the fixing pin 65 and the pressing strip 66 to rotate. The rotating third gears 63 are used to drive the pressing strip 66 to press the cylindrical surface of the second fixing roller 4 so that the two layers of fabric are tightly bonded together. The fixing pin 65 drives the pressing strip 66 to rotate, and the pressing strip 66 can press the polyester base fabric and the waterproof and breathable membrane that have just been bonded together to ensure that the polyester base fabric and the waterproof and breathable membrane are bonded together.
[0024] Please refer to Figures 7-9. A connecting strip 67 is provided between the two third side strips 62 and below the fixing pin 65. Both ends of the connecting strip 67 are integrally manufactured with connecting shafts 64. The connecting shafts 64 at both ends of the connecting strip 67 are welded to the two third side strips 62 respectively. The two ends of the connecting strip 67 are fixed to the third side strips 62 on both sides through the connecting shafts 64, thereby fixing the third side strips 62 and the connecting strip 67 together. A pressure roller 68 is provided on the edge of the connecting strip 67. The cylindrical surface of the pressure roller 68 presses against the fabric at the second fixing roller 4. Since the pressure roller 68 presses against the fabric on both sides, the adhesive between the fabrics can be squeezed, avoiding the adhesive between the fabrics from being concentrated in one place or unevenly distributed.
[0025] Please refer to Figure 9. The outer side of the pressing roller 68 is pressed with a mesh embossing 69. The two ends of the pressing roller 68 are rotatably connected to the two ends of the edge of the connecting strip 67. The pressing roller 68 is used to compact the adhesive between the two layers of fabric. The connecting strip 67 can be fixed on the third side strip 62. The pressing roller 68 and the mesh embossing 69 can spread the adhesive of the two layers of fabric evenly.
[0026] Please refer to Figure 10. A waterproof coating composite process for polyester fabric, based on the aforementioned waterproof coating composite equipment for polyester fabric, includes the following steps: S1, Pre-processing: Dry the polyester fabric, preheat the equipment and calibrate the system. Load the polyester base fabric and waterproof breathable membrane onto the independent double unwinding rollers of the equipment. Dry the polyester fabric to a moisture content ≤3%, ensuring that the fabric surface is free of oil, impurities, and water stains. After drying the hot melt adhesive, ensure a moisture content ≤0.05% to prevent the polyester fabric and hot melt adhesive from absorbing moisture and attracting dust. Preheat the adhesive melting zone and hot pressing composite zone of the equipment. S2, Simultaneous unwinding of dual materials: The polyester base fabric and waterproof breathable membrane are discharged through independent unwinding rollers, with independent control of dual-path constant tension to avoid... To prevent wrinkles in the polyester base fabric and waterproof breathable membrane, the polyester base fabric tension is 8-12N, and the waterproof breathable membrane tension is 3-5N. S3, Targeted pretreatment of both materials: Hot air preheating of the polyester fabric to increase its surface temperature, and low-temperature preheating of the membrane material, are performed simultaneously to prepare for subsequent lamination. Oil stains on the polyester fabric surface are removed, and then it enters the hot air preheating zone at 50-70℃ to increase the fabric surface temperature and enhance the wettability of the adhesive. The waterproof breathable membrane enters the low-temperature preheating zone at 40-60℃, only increasing the membrane surface temperature to prevent membrane embrittlement and shrinkage. S4, Guiding the waterproof breathable membrane: The waterproof breathable membrane is guided along the guide plate 55 of the fabric tensioning component 5 to ensure that the waterproof breathable membrane enters the... S5. Laying the polyester base fabric and waterproof breathable membrane together: The adhesive-coated waterproof breathable membrane is bonded to the preheated polyester base fabric, achieving precise alignment and bonding at the first fixed roller 3 and the second fixed roller 4, laying the groundwork for subsequent hot pressing. The polyester base fabric and waterproof breathable membrane are in close contact at the first fixed roller 3 and the second fixed roller 4. The fixed rollers apply slight pressure to expel the air gap between the fabric and the membrane; S6. Hot pressing the polyester base fabric and waterproof breathable membrane: The polyester base fabric and waterproof breathable membrane are heated using the internal heating device of the first fixed roller 3 or the second fixed roller 4 to ensure that the polyester base fabric and waterproof breathable membrane are bonded together. The fixed rollers and the metal heaters combine to form a heating element. The heated fixed roller achieves complete bonding of the adhesive layer to the fabric and membrane through hot pressing; S7, the bonded polyester base fabric and waterproof and breathable membrane are tightly adhered: the pressing strip 66 and the pressing roller 68 press the polyester base fabric and waterproof and breathable membrane against the cylindrical surface of the second fixed roller 4; S8, the composite fabric is trimmed: the two sides of the fabric are trimmed by a CNC trimming knife to ensure that the width of the finished fabric is uniform. If there are rough edges or excess adhesive on the two sides of the composite fabric, they are trimmed by the trimming knife to ensure that the width of the finished fabric is uniform; S9, finished fabric inspection and finished fabric winding: the finished fabric is inspected for delamination and curling edges. The qualified composite fabric is wound up by the winding roller to ensure that the roll is flat, avoids damage to the waterproof membrane layer, and facilitates subsequent curing, warehousing, and transportation.
[0027] In S1, the polyester fabric is dried to a moisture content of ≤3%, and the hot melt adhesive is dried to a moisture content of ≤0.05% to avoid moisture absorption and dust adhesion. The polyester base fabric and the waterproof and breathable membrane are located in two rollers and return to the third roller via each roller shaft. In S3, the preheating temperature of the polyester base fabric is 50-70℃, and the preheating temperature of the waterproof and breathable membrane is 40-60℃. The waterproof and breathable membrane is subjected to static electricity elimination rods to prevent dust and impurities from adsorbing onto the membrane surface.
[0028] In steps S1 to S9, the speed of the polyester base fabric and waterproof breathable membrane is controlled at 15-30 m / min throughout the process; in step S4, the guide plate 55 guides the waterproof breathable membrane while adhering it to the surface of the polyester fabric; in step S7, the pressing strip 66 is used to compact the polyester base fabric and the waterproof breathable membrane, and the pressing roller 68 is used to smooth the adhesive in the gap between the polyester base fabric and the waterproof breathable membrane, so as to avoid the adhesive from accumulating between the first fixed roller 3 and the second fixed roller 4.
