Description

Technical Field

[0001] This invention relates to the field of fine checkered fabric technology, and in particular to a three-in-one all-polyester matte fine checkered fabric and its preparation process. Background Technology

[0002] Fine check fabric is a type of fabric with a small, regular check pattern on its surface. It belongs to the category of printed or yarn-dyed fabrics. Due to its classic appearance and diverse properties, it is widely used in clothing, home textiles and other fields. It is often used to make shirts, dresses, trousers, curtains, tablecloths, etc., adding a simple, fashionable or retro style to the products. Among them, all-polyester fine check fabric is widely used in the field of functional fabrics due to its high strength, durability and easy care.

[0003] In the existing technology, the fine-grid polyester fabric itself has poor moisture absorption, which makes it feel stuffy and not breathable when worn. In addition, since the cooling roller is usually set only once, the cooling speed on both sides of the fabric is inconsistent, resulting in curling, wrinkling and unevenness of the finished product. Summary of the Invention

[0004] In the prior art, the 100% polyester fine check fabric itself has poor moisture absorption, which leads to a stuffy and non-breathable feeling when wearing it. In addition, since the cooling roller is usually set only once, the cooling speed on both sides of the fabric is inconsistent, resulting in technical problems such as curling, wrinkling and unevenness of the finished product. The present invention proposes a three-in-one 100% polyester matte fine check fabric and its preparation process.

[0005] The present invention proposes a three-in-one all-polyester matte fine check fabric and its preparation process, including a fabric body, wherein the fabric body is formed by laminating a bottom layer, a middle layer and a top layer through a hot melt adhesive composite process.

[0006] Preferably, the surface layer is located on the upper surface of the intermediate layer, and the surface layer is a 20D all-polyester matte fine checkered pattern, woven from 100% polyester fiber material.

[0007] Through the above technical solution, the outer layer is located on the upper surface of the middle layer, which can effectively resist external wear and protect the internal TPU film. At the same time, it can prevent the fabric from wrinkling and deforming during use. The outer layer material is made of 20D full polyester matte fine grid pattern, which makes the fabric surface have a soft and low-key luster, avoiding the cheap reflective feeling of ordinary chemical fiber fabrics. The fine grid pattern structure increases the visual layering and texture beauty of the fabric surface.

[0008] Preferably, the intermediate layer is made of TPU film to provide waterproof, windproof, and breathable barrier properties.

[0009] Through the above technical solution, the middle layer is located between the top layer and the bottom layer. It is made of TPU film and has excellent waterproof and windproof performance. It can effectively block external rain and cold wind from intruding. At the same time, its unique molecular structure allows water vapor molecules to pass through, achieving the dual functions of waterproof and breathable, keeping the wearer's body dry. It has good elasticity and flexibility, and can stretch freely with body movements without restricting the wearer's range of motion, thus improving comfort.

[0010] Preferably, the bottom layer is located on the lower surface of the intermediate layer, and the bottom layer is 30D fully coated yarn woven from 100% polyester fiber.

[0011] Through the above technical solution, the bottom layer is located on the lower surface of the middle layer, providing physical protection for the TPU film and preventing it from being corroded by sweat or damaged by friction from underwear. At the same time, it can cover the hot melt adhesive residue on the film, ensuring a clean and beautiful appearance of the inner layer. The bottom layer uses 30D fully coated yarn, which is the layer that comes into direct contact with the skin. It has the characteristics of being lightweight, soft, and smooth, which can effectively cover the stiffness or stickiness that the middle TPU film may have, thereby significantly improving the comfort of wearing it close to the skin. The three-layer design of the fabric body realizes the design concept of external protection and internal comfort. The fine grid pattern of the surface layer and the yarn structure of the bottom layer form a soft-hard-soft sandwich structure on both sides of the TPU film, which not only ensures the overall crispness and shape of the fabric, but also takes into account the softness and skin-friendly feel of the side that touches the skin.

[0012] The present invention proposes a preparation process for a three-in-one all-polyester matte fine-grid fabric, which includes the following steps; Step 1: Prepare a 20D all-polyester matte fine-grid top layer, a TPU film middle layer, and a 30D all-coated yarn bottom layer, all made of 100% polyester fiber. Step 2: Using a hot melt adhesive laminating machine, the hot melt adhesive is heated and melted and applied to the upper and lower surfaces of the intermediate layer. The top layer is then placed over the upper surface of the intermediate layer, and the bottom layer is placed over the lower surface of the intermediate layer. After being hot-pressed by hot rollers, the three layers are firmly bonded together to form a composite fabric. Step 3: Introduce the composite fabric body into a cooling machine for rapid cooling and shaping, solidify the interlayer adhesive, and stabilize the fabric structure. Step 4: Roll up the cooled and set fabric to obtain the finished product.

[0013] Preferably, the cooling machine in step three includes a frame, and a cooling mechanism is provided inside the frame. The cooling mechanism includes a cooling roller with a spiral channel, and the cooling roller rapidly absorbs heat and cools the fabric body that is attached to its roller surface through heat conduction.

[0014] The frame is equipped with an air-cooling mechanism, which includes a cooling frame. The cooling frame uses its air vents to force convection heat dissipation onto the pre-cooled fabric body.

[0015] Preferably, the cooling mechanism further includes an electric push rod, which is fixedly installed in the top groove of the frame. A lifting frame is fixedly installed at one end of the telescopic rod of the electric push rod. The lifting frame is slidably inserted into the inner wall of the grooves on both sides of the frame. One cooling roller is rotatably connected to the mounting slots on both sides of the lifting frame through bearings, and the other cooling roller is rotatably connected to the mounting slots on both sides of the frame through bearings.

[0016] The above technical solution involves fixing the electric push rod to the frame and then fixing it to the frame via the extension rod of the electric push rod. The extension and retraction of the extension rod can drive the lifting frame to slide within the groove of the frame, thereby adjusting the height of the cooling rollers that are rotatably connected to it. This changes the distance between the two cooling rollers, allowing for flexible adjustment of pressure and gap based on the total thickness of the fabric body, ensuring that fabric bodies of various specifications can obtain the best contact cooling effect.

[0017] Preferably, a cooling pump, a heat exchanger, and a liquid storage tank with a filter screen are fixedly installed on the upper surface of the bottom support plate of the frame. The water inlet of the cooling pump is fixedly connected to the liquid outlet of the liquid storage tank through a pipe. The water outlet of the cooling pump is fixedly connected to an inlet hose through a tee fitting. The two inlet pipes of the inlet hose are fixedly connected to the inlet ports of the two cooling rollers, respectively. The input end of the heat exchanger is fixedly connected to an outlet hose through a tee fitting. The two outlet pipes of the outlet hose are fixedly connected to the outlet ports of the two cooling rollers, respectively. The output end of the heat exchanger is fixedly connected to the return port of the liquid storage tank through a pipe. The filter screen of the liquid storage tank is located below the return port of the liquid storage tank.

[0018] The above technical solution involves fixing the cooling pump, heat exchanger, and liquid storage tank to the frame. The cooling pump serves as the circulating power source, with its inlet connected to the outlet of the liquid storage tank via a pipe, drawing coolant from the tank. Its outlet is split via a three-way fitting, connecting to two separate inlet hoses to simultaneously deliver the coolant to the inlet ports of the two cooling rollers, achieving parallel liquid feeding for both rollers. The cooling rollers, acting as heat exchange actuators, have their outlets connected to another three-way fitting via two outlet hoses, and then... The heat exchanger is connected to the input end, and the heated cooling liquid after absorbing the heat of the fabric body is collected and transported to the heat exchanger. The heat exchanger acts as the core of cooling. Its output end is connected to the return port of the liquid storage tank through a pipe. The cooled liquid flows back into the liquid storage tank. By setting a filter screen below the return port of the liquid storage tank, the return liquid must be filtered through the filter screen before it can re-enter the liquid storage tank cavity, intercepting pipeline impurities or wear particles entrained in the cooling liquid, and preventing foreign objects from entering the cooling pump or clogging the precision spiral channel inside the cooling roller.

[0019] Preferably, the air-cooling mechanism further includes a fan, which is fixedly installed in the top groove of the frame. The air inlet of the fan is fixedly connected to an air inlet pipe with a filter screen, and the air outlet of the fan is connected to a diverter pipe. The two outlets of the diverter pipe are respectively fixedly connected to the air inlets of the two cooling frames. The two cooling frames are respectively fixedly installed on the top and bottom walls of the cooling channel of the frame and are arranged opposite to each other.

[0020] The above technical solution involves fixing the fan to the frame and installing a filter at the fan's inlet to intercept dust, lint, and other particulate matter in the air, preventing impurities from adhering to the surface of the fabric before it has fully cooled and set, or from clogging the air vents of the cooling frames. The fan's outlet is connected to a distribution pipe, evenly distributing a single stream of air to two outlets, which are connected to the air inlets of the two cooling frames. This ensures that both cooling frames receive an equal amount of cold air simultaneously, avoiding cooling differences caused by uneven airflow distribution. The two cooling frames are fixedly installed on the top and bottom walls of the frame's cooling channel, respectively, and are positioned opposite each other, providing simultaneous counter-blowing cooling to both sides of the fabric. This improves the fabric's setting efficiency and eliminates bulging, wrinkling, or residual internal stress caused by uneven cooling and shrinkage.

[0021] The beneficial effects of this invention are as follows: 1. By setting up a bottom layer, middle layer, and top layer, the top layer is located on the upper surface of the middle layer, effectively resisting wear and protecting the internal TPU film. The 20D all-polyester matte fine check pattern gives the fabric a soft luster and unique texture. The middle layer uses a TPU film, which has excellent waterproof, windproof, and breathable properties to block wind and rain and keep you dry. Its elasticity ensures freedom of movement. The bottom layer is located on the lower surface of the middle layer, protecting the film from sweat corrosion and friction damage, covering glue marks to ensure aesthetics. The 30D fully coated yarn material is light and soft, covering the stiffness of the film and significantly improving skin-friendly comfort. This solves the technical problem in existing technologies where all-polyester fine check fabric itself has poor moisture absorption, resulting in a stuffy feeling and lack of breathability when worn.

[0022] 2. By setting up a cooling machine, an electric push rod drives the lifting frame to slide, adjusting the spacing of the cooling rollers to adapt to fabrics of different thicknesses and ensure the best contact cooling effect. The cooling pump, heat exchanger and liquid storage tank form a closed-loop system. Two cooling rollers are connected in parallel to receive liquid through a three-way pipe fitting to ensure uniform cooling. The filter screen filters backflow impurities to prevent blockage of the precision spiral channel. The fan distributes clean airflow evenly to the cooling frame through a distribution pipe, and the top and bottom blowing achieves double-sided air cooling. This solves the technical problem in the existing technology where the cooling roller is usually set alone, resulting in inconsistent cooling speeds on both sides of the fabric, which leads to curling, wrinkling and unevenness in the finished product.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Reference Figures 1-10 A three-in-one all-polyester matte fine check fabric and its preparation process, comprising a fabric body 1, wherein the fabric body 1 is formed by laminating a bottom layer 3, a middle layer 21 and a top layer 2 through a hot melt adhesive composite process.

[0027] Specifically, in order to increase the visual layering and textural beauty of the fabric body 1, the outer layer 2 is located on the upper surface of the middle layer 21. The outer layer 2 is a 20D full polyester matte fine check pattern, woven from 100% polyester fiber. By being located on the upper surface of the middle layer 21, the outer layer 2 can effectively resist external wear and tear, protect the internal TPU film, and prevent the fabric from wrinkling and deforming during use. The use of 20D full polyester matte fine check pattern as the outer layer material makes the fabric surface have a soft and understated luster, avoiding the cheap reflective feel of ordinary chemical fiber fabrics. The fine check pattern structure increases the visual layering and textural beauty of the fabric body 1.

[0028] Specifically, in order to block the intrusion of external rain and cold wind, the intermediate layer 21 is made of TPU film, which serves as a waterproof, windproof and breathable barrier. The intermediate layer 21 is located between the top layer 2 and the bottom layer 3. It is made of TPU film and has excellent waterproof and windproof performance. It can effectively block the intrusion of external rain and cold wind. At the same time, its unique molecular structure allows water vapor molecules to pass through, achieving the dual functions of waterproof and breathable, keeping the wearer's body dry. It has good elasticity and flexibility, and can stretch freely with body movements without restricting the wearer's range of motion, thus improving comfort.

[0029] Specifically, to prevent the film from being corroded by sweat or damaged by friction from underwear, the bottom layer 3 is located on the lower surface of the middle layer 21. The bottom layer 3 is made of 30D fully coated yarn and woven from 100% polyester fiber. The bottom layer 3 provides physical protection for the TPU film, preventing it from being corroded by sweat or damaged by friction from underwear. At the same time, it can cover the hot melt adhesive residue on the film, ensuring that the inner layer looks clean and beautiful. By using 30D fully coated yarn as the layer that directly contacts the skin, the bottom layer 3 has the characteristics of being light, soft and smooth, which can effectively cover the stiffness or stickiness that the TPU film in the middle layer 21 may have, thereby significantly improving the comfort of wearing it close to the skin. The three-layer design of the fabric body 1 realizes the design concept of external protection and internal comfort. The fine grid pattern of the surface layer 2 and the yarn structure of the bottom layer 3 form a soft-hard-soft sandwich structure on both sides of the TPU film, which not only ensures the overall crispness and shape of the fabric, but also takes into account the softness and skin-friendly feel of the side that is close to the skin.

[0030] The present invention proposes a preparation process for a three-in-one all-polyester matte fine-grid fabric, which includes the following steps; Step 1: Prepare a 20D all-polyester matte fine-grid top layer 2, a TPU film intermediate layer 21, and a 30D all-coated yarn bottom layer 3, all made of 100% polyester fiber. Step 2: Using a hot melt adhesive laminating machine, the hot melt adhesive is heated and melted and applied to the upper and lower surfaces of the intermediate layer 21. The top layer 2 is covered on the upper surface of the intermediate layer 21, and the bottom layer 3 is covered on the lower surface of the intermediate layer 21. After being hot-pressed by hot press rollers, the three layers of materials are firmly bonded to form a composite fabric. Step 3: Introduce the composite fabric body 1 into a cooling machine for rapid cooling and shaping, solidify the interlayer adhesive, and stabilize the fabric structure. Step 4: Roll up the cooled and shaped fabric body 1 to obtain the finished product.

[0031] like Figure 3-7 As shown, the cooling machine in step three includes a frame 4, and a cooling mechanism is provided inside the frame 4. The cooling mechanism includes a cooling roller 52 with a spiral channel. The cooling roller 52 rapidly absorbs heat and cools the fabric body 1 that is attached to its roller surface through heat conduction.

[0032] Specifically, in order to drive the lifting frame 51 to slide within the groove of the frame 4, the cooling mechanism also includes an electric push rod 5. The electric push rod 5 is fixedly installed in the top groove of the frame 4. The lifting frame 51 is fixedly installed at one end of the telescopic rod of the electric push rod 5. The lifting frame 51 is slidably inserted into the inner wall of the grooves on both sides of the frame 4. One cooling roller 52 is rotatably connected to the mounting slots on both sides of the lifting frame 51 through bearings, and the other cooling roller 52 is rotatably connected to the mounting slots on both sides of the frame 4 through bearings. The electric push rod 5 is fixedly installed to the frame 4, and the telescopic rod of the electric push rod 5 is fixedly installed to the lifting frame 51. The extension and retraction of the telescopic rod can drive the lifting frame 51 to slide within the groove of the frame 4, thereby adjusting the height position of the cooling roller 52 rotatably connected to it, thereby changing the distance between the two cooling rollers 52. This allows for flexible adjustment of pressure and gap according to the total thickness of the fabric body 1, ensuring that the fabric body 1 of various specifications can obtain the best contact cooling effect.

[0033] Specifically, to intercept pipe impurities or wear particles entrained in the coolant, a cooling pump 6, a heat exchanger 61, and a storage tank 62 with a filter screen are fixedly installed on the upper surface of the bottom support plate of the frame 4. The inlet of the cooling pump 6 is fixedly connected to the outlet of the storage tank 62 via a pipe, and the outlet of the cooling pump 6 is fixedly connected to an inlet hose 7 via a T-fitting. The two inlet pipes of the inlet hose 7 are fixedly connected to the inlet ports of the two cooling rollers 52, respectively. The input end of the heat exchanger 61 is fixedly connected to an outlet hose 71 via a T-fitting. The two outlet pipes of the outlet hose 71 are fixedly connected to the outlet ports of the two cooling rollers 52, respectively. The output end of the heat exchanger 61 is fixedly connected to the return port of the storage tank 62 via a pipe. The filter screen of the storage tank 62 is located below the return port of the storage tank 62. The cooling pump 6, heat exchanger, and storage tank 62 are fixedly installed and secured to the frame 4. The cooling pump 6 serves as a circulating power source, and its inlet is connected to the... The coolant is drawn from the outlet of the storage tank 62. Its outlet is split via a three-way fitting, connecting to two inlet hoses 7, simultaneously delivering the coolant to the inlet ports of the two cooling rollers 52, achieving parallel liquid inlet for both rollers. The cooling rollers 52 serve as heat exchange actuators; their outlets are connected to another three-way fitting via two outlet hoses 71, which are then connected to the input port of the heat exchanger 61. This process collects and delivers the heated coolant, after absorbing heat from the fabric body 1. The coolant is sent to heat exchanger 61, which serves as the core of cooling. Its output end is connected to the return port of the liquid storage tank 62 through a pipe. After cooling, the coolant flows back into the liquid storage tank 62. By setting a filter screen below the return port of the liquid storage tank 62, the return liquid must be filtered through the filter screen before it can re-enter the cavity of the liquid storage tank 62. This intercepts pipe impurities or wear particles carried in the coolant, preventing foreign objects from entering the cooling pump 6 or clogging the precision spiral channel inside the cooling roller 52.

[0034] like Figure 8-10 As shown, in order to perform forced convection heat dissipation on the pre-cooled fabric body 1, the frame 4 is equipped with an air-cooling mechanism, which includes a cooling frame 83. The cooling frame 83 performs forced convection heat dissipation on the pre-cooled fabric body 1 through its air vents. Specifically, to ensure that the two cooling frames 83 can simultaneously receive an equal amount of cold airflow, the air-cooling mechanism also includes a fan 8. The fan 8 is fixedly installed in the top recess of the frame 4. The air inlet of the fan 8 is fixedly connected to an air inlet pipe 81 with a filter screen, and the air outlet of the fan 8 is connected to a split pipe 82. The two outlets of the split pipe 82 are respectively fixedly connected to the air inlets of the two cooling frames 83. The two cooling frames 83 are respectively fixedly installed on the top and bottom walls of the cooling channel of the frame 4 and are arranged opposite to each other. The fan 8 is fixedly installed to the frame 4, and the filter screen installed at the air inlet pipe 81 of the fan 8 intercepts dust, lint, and other particulate matter in the air to prevent impurities. The airflow adhering to the surface of the fabric body 1 that has not yet been fully cooled and set, or the air vents blocking the cooling frame 83, is connected to the distribution pipe 82 through the air outlet of the fan 8, so that the single airflow is evenly distributed to the two outlets, which are connected to the air inlets of the two cooling frames 83 respectively. This ensures that the two cooling frames 83 can obtain an equal amount of cold airflow at the same time, avoiding cooling differences caused by uneven airflow distribution. The two cooling frames 83 are fixedly installed on the top and bottom walls of the cooling channel of the frame 4 respectively, and are arranged opposite each other, so as to perform counter-blowing air cooling on both sides of the fabric body 1 at the same time, thereby improving the setting efficiency of the fabric and eliminating bulging, wrinkling or residual internal stress caused by uneven cooling and shrinkage of the fabric body 1.

[0035] Working principle: When the control system is activated, the operator sets parameters such as the spacing of the cooling rollers 52, the flow rate of the coolant, and the wind speed of the fan 8 on the control panel according to the total thickness and material characteristics of the fabric body 1. The control system sends a command to the electric push rod 5. The telescopic rod of the electric push rod 5 extends or retracts, driving the lifting frame 51 to slide vertically along the inner wall of the groove on both sides of the frame 4. The cooling rollers 52 installed on the lifting frame 51 rise and fall accordingly, thereby adjusting the vertical distance between the two cooling rollers 52. After adjustment, the control system starts the cooling pump 6, and the coolant in the storage tank 62 is drawn out. After being diverted by the three-way fitting, it is simultaneously injected into the inlet of the two cooling rollers 52 through two inlet hoses 7. The coolant flows in the spiral channel inside the cooling roller 52, absorbs heat and rises in temperature, and flows out from the outlet. After being merged by the two outlet hoses 71, it enters the heat exchanger 61. The heat exchanger 61 cools down the high temperature coolant. The cooled liquid flows back to the storage tank 62. The returned liquid is filtered by the filter screen to remove impurities and then participates in the circulation again. At this point, the cooling roller 52 is in standby cooling state. The roller surface temperature drops to the set value. The control system starts the fan 8, and outside air is drawn in through the air inlet pipe 81. The air inlet filter removes dust and impurities. The clean airflow is evenly distributed through the diversion pipe 82 and enters through the air inlet of the two cooling frames 83. The two cooling frames 83 are located on the top and bottom walls of the cooling channel of the frame 4, respectively, and are set opposite each other, ready to perform double-sided air cooling on the fabric. The fabric body 1, after being laminated with hot melt adhesive, is introduced into the cooling machine, passing through two cooling rollers 52 and two cooling frames 83 in sequence, and is fixedly connected to the take-up roller. The take-up roller starts to provide traction power. Since the gap between the cooling rollers 52 has been pre-adjusted to a suitable size, the fabric body 1 is moderately clamped between the two roller surfaces, so that its upper and lower surfaces are in close contact with the low-temperature roller surfaces. Heat is quickly transferred to the cooling medium in the cooling rollers 52 through heat conduction, achieving initial rapid cooling, which promotes the rapid curing of the hot melt adhesive and completes the interlayer structure shaping. Subsequently, the fabric body 1, after initial cooling, continues to move, passing through the cooling channel between the two cooling frames 83. The air vents of the upper and lower cooling frames 83 simultaneously blow directional cold air at both sides of the fabric body 1, further removing the deep residual heat of the fabric through forced convection heat dissipation, achieving uniform cooling on both sides.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
