Description

Technical Field

[0001] This invention relates to the field of composite knitted fabrics, specifically a process for preparing composite knitted fabrics containing popping beads. Background Technology

[0002] With the improvement of people's living standards and the enhancement of health awareness, functional textiles are receiving increasing attention. Antibacterial, aromatic, and moisturizing functions have become important factors for consumers when choosing textiles. These functional textiles can bring more convenience and comfort to people's lives, while also helping to improve their quality of life. However, currently available functional textiles still have certain shortcomings in terms of the durability, stability, and diversity of their functions.

[0003] As a novel technology, burst beads have demonstrated enormous application potential in other fields. Their unique structure allows functional substances to be encapsulated and released through specific triggering mechanisms, thus achieving specific functions. Introducing burst bead technology into the production of composite knitted fabrics is expected to endow textiles with new functional properties, meeting consumers' diverse needs for functional textiles.

[0004] While current composite knitted fabrics combine the advantages of different materials to some extent, they still lack in terms of functional integration and innovation. For example, existing composite knitted fabrics often struggle to achieve multiple functions simultaneously, and the methods of adding functional substances are relatively simple, resulting in less than ideal durability and stability of the functions. Furthermore, existing production processes suffer from low efficiency and high costs, limiting the large-scale application and promotion of composite knitted fabrics.

[0005] With the continuous improvement of people's living standards, the requirements for the functionality and comfort of textiles are also increasing. Composite knitted fabrics, due to their excellent elasticity, breathability, and comfort, have been widely used in clothing, home furnishings, and other fields. However, existing composite knitted fabrics still have certain functional limitations and cannot meet people's needs for special functions. Bursting beads, as a novel functional material, possess unique structure and properties. Applying bursting beads to composite knitted fabrics can endow them with more functions, such as antibacterial, fragrance, and moisturizing properties. Therefore, it is necessary to propose a preparation process for composite knitted fabrics containing bursting beads. Summary of the Invention

[0006] The purpose of this invention is to solve the problems in the background art and provide a process for preparing composite knitted fabric containing popping beads.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A process for preparing a composite knitted fabric containing popping beads includes the following steps: S1, Softening and drying: The upper knitted fabric is softened by a softening impregnation device (9) and then dried. S2, continuously apply burst beads, the burst beads are positioned and quantitatively discharged by the positioning and quantitative discharge mechanism (1) of the burst bead adding device, and the burst beads are continuously sprinkled on the bottom layer of high-loft hot air nonwoven fabric to form three or more uninterrupted burst bead layers; S3, spray glue and flip, the upper knitted fabric is positioned and sprayed glue through the positioning spray glue mechanism (2), no glue is sprayed at the position corresponding to the popping beads, after spraying glue, flip and cover the high-loft hot air non-woven fabric containing popping beads. S4, Close the bursting beads, heat and roll the high-loft hot air nonwoven fabric and knitted fabric containing bursting beads through the rolling mechanism (3) to seal the bursting beads between the bottom high-loft hot air nonwoven fabric and knitted fabric to form a composite knitted fabric; S5, Drying and curing: Drying and curing the composite knitted fabric with sealed popping beads.

[0008] This invention involves softening the upper layer of knitted fabric using a softening impregnation device, followed by drying to reduce static electricity and enhance its softness. Then, burst beads are continuously sprinkled onto the center of a high-loft hot-air nonwoven fabric. Adhesive is then sprayed onto the upper surface of the upper knitted fabric, except at the location opposite the burst beads, ensuring no hot-melt adhesive is applied to the beads and preventing them from becoming trapped and unable to burst later. The upper knitted fabric is then flipped so that its upper surface faces downwards, and together with the high-loft hot-air nonwoven fabric containing the burst beads, they are longitudinally rolled by a rolling mechanism. This seals the burst beads between the bottom high-loft hot-air nonwoven fabric layer and the upper knitted fabric, forming a composite knitted fabric containing burst beads. After drying and curing, a composite knitted fabric containing burst beads is produced, giving the fabric more functions such as antibacterial, fragrance, and moisturizing properties, meeting people's needs for functional textiles. The burst beads are firmly bonded to the knitted fabric, are not easily detached, and have a long service life.

[0009] Upper knitted fabric Knitted fabrics are typically made from natural fibers (such as cotton, linen, and silk) or synthetic fibers (such as polyester, nylon, and spandex). These fibers offer excellent elasticity, breathability, and moisture absorption, providing a comfortable experience for the wearer. The weave structure of knitted fabrics gives them a soft feel and good stretch, allowing them to adapt to the body's movements and changes.

[0010] As the outer layer of the beaded knit fabric, the upper knit fabric protects the beads and provides a comfortable feel. It prevents the beads from being damaged by external friction, while also providing a soft contact surface for the wearer.

[0011] The upper knitted fabric can also be dyed, printed, or otherwise treated as needed to enhance its aesthetics and fashion sense.

[0012] 2. Lower layer high-loft hot air nonwoven fabric High-loft hot-air nonwoven fabric is typically made of synthetic fibers such as polypropylene and polyester. It features high loft, softness, and breathability, providing excellent support and protection for the pods.

[0013] The production process of hot-air nonwoven fabric gives it a uniform fiber distribution and good strength, enabling it to withstand certain pressure and tension.

[0014] As the inner layer of the burst bead knitted fabric, the lower layer of high-loft hot-air nonwoven fabric plays a role in supporting the burst beads and maintaining their stability. Its high loft provides sufficient space for the burst beads, preventing them from being squeezed and broken during use.

[0015] The breathability of hot-air nonwoven fabric allows the functional substances in the capsules to be released smoothly and perform their intended function. At the same time, it also prevents substances in the capsules from permeating into the external environment, maintaining the capsules' seal and stability.

[0016] III. Distribution and Function of Bursting Beads Between the Two Layers Distribution method Bursting beads are typically evenly distributed between an upper layer of knitted fabric and a lower layer of high-loft hot-air nonwoven fabric. Special production processes, such as spraying or impregnation, can be used to fix the bursting beads between the two layers, ensuring their stability and uniformity.

[0017] Functions and roles The capsules contain various functional substances, such as antibacterial agents, fragrances, and moisturizers. When subjected to external pressure or friction, the capsules burst, releasing these functional substances to provide the wearer with the corresponding benefits.

[0018] The presence of burst beads can give knitted fabrics more functions and properties to meet the needs of different consumers. For example, antibacterial burst beads can provide antibacterial protection for the wearer, aromatic burst beads can bring the wearer a pleasant fragrance, and moisturizing burst beads can provide moisturizing effects for the wearer's skin.

[0019] The bursting bead adding device includes a frame. From left to right, the frame is sequentially equipped with a positioning and metering dispensing mechanism and a rolling mechanism. Above the rolling mechanism are a longitudinal positioning glue spraying mechanism and a transverse glue spraying mechanism, which are arranged in parallel. Below these mechanisms are two parallel first guide rollers. To the left of the rolling mechanism is a second guide roller for flipping the upper knitted fabric. The entire device is automated, reducing manual labor, improving production efficiency, ensuring hygiene, and is suitable for large-scale production.

[0020] The positioning and quantitative discharging mechanism includes a storage hopper, a feeding pipe, a limiting cover, and a feeding roller arranged sequentially from top to bottom on the frame. The feeding pipe is located between two through slots. The inside of the limiting cover is a cavity. An arc-shaped limiting opening is formed on the side of the limiting cover near the feeding roller to facilitate the rotation of the feeding roller. The gap between the arc-shaped limiting opening and the feeding roller is smaller than the outer dimensions of the material. The roller surface of the feeding roller has several popping bead discharge grooves along the circumferential direction. Three or more sets of popping bead discharge grooves are arranged along the axial direction of the feeding roller. The area formed between two adjacent partition plates corresponds to one set of popping bead discharge grooves. When the partition plates are not in use, they are placed in a designated position for easy retrieval.

[0021] The material limiting cover of the present invention is used to prevent the material from falling off the feeding roller before it is transported to the nonwoven fabric. The popping beads are dropped onto the top surface of the feeding roller through the feeding pipe via the storage hopper. The excess popping beads are scraped off by the material limiting cover. Only the popping beads that fall into the popping bead discharge groove are continuously and evenly scattered onto the high-loft hot air nonwoven fabric, thereby realizing the step of uninterrupted application of popping beads.

[0022] The top of the material limiting cover has two or more through slots along its length. Above the through slots is a partition plate that can be inserted into the through slots. Both sides of the top of the partition plate are fixed with limiting pieces. When separation is required, the partition plate is inserted into the through slot, and the limiting pieces are located above the through slot, thereby realizing a detachable partition plate.

[0023] This invention allows for the addition of several rows of burst beads as needed by inserting a separator plate into the limiting cover, thereby increasing the applicability of the device.

[0024] Preferably, the rolling mechanism includes a heating roller and a popping bead fixing roller rotatably mounted on a frame. The popping bead fixing roller is positioned above the heating roller and includes a hollow roller body. A rotating shaft is fixed to the center of the roller body, and the rotating shaft is fixedly connected to the inner side of the roller body via a support bar. The roller body can be divided into a front rolling zone, a popping bead avoidance zone, and a rear rolling zone along the axial direction. The surface of the popping bead avoidance zone has an annular groove along the circumferential direction. There are three or more annular grooves arranged in an array along the axial direction. Several transverse rolling plates are evenly distributed on the annular grooves, and the transverse rolling plates and the roller body form a popping bead receiving cavity.

[0025] The heating roller can be heated by electric heating wire or heat transfer oil. This is a mature technology and will not be elaborated on in this case.

[0026] This invention, through the cooperation of the front and rear rolling areas of the burst bead fixing roller and the burst bead receiving cavity, allows the upper knitted fabric after spraying glue and the high-loft nonwoven fabric with added burst beads to be laminated. Only the areas without burst beads are hot-rolled, while the areas with burst beads are not squeezed due to the annular grooves. This completes the sealing of the burst beads within the laminated knitted fabric. At the same time, the transverse rolling plate can fix the burst beads within a square frame to prevent them from shifting.

[0027] Preferably, the bottom of the burst bead receiving cavity has several through holes, each with a plug. A radial telescopic mechanism is connected to the inner side of each set of plugs located within an annular groove. The plugs move radially within the burst bead receiving cavity via the radial telescopic mechanism. An annular slit-filled silicone plate is fixed to the opening of the burst bead receiving cavity. The use of a silicone plate structure makes the material soft, preventing compression of the burst beads when used as a burst bead avoidance zone.

[0028] This invention controls the insertion and exit of the plug core into the burst bead receiving cavity through a radial telescopic mechanism. When the top of the plug core extends to the groove of the burst bead receiving cavity, it cooperates with the annular gap-filling silicone plate to form a rolling surface identical to the rolling zone. When the plug core is retracted into the through hole, a groove is formed, creating a burst bead avoidance zone. This allows it to work with a separator plate, enabling the user to select the number of rows of burst beads to add.

[0029] Preferably, the radial telescopic mechanism includes an inner fixed ring, an outer fixed ring, a rack, a gear, and an internal gear. The rack is located above the internal gear. The outer fixed ring is located outside the inner fixed ring and is concentrically arranged with it. A gear placement space is formed between the outer fixed ring and the inner fixed ring. Radial grooves are formed in the radial direction of the outer fixed ring and the inner fixed ring. The number of radial grooves is the same as the number of plugs in each set on the annular groove. The rack is slidably disposed in the radial groove. The gear is disposed in the gear placement space and meshes with the rack. The internal gear is disposed inside the outer fixed ring and meshes with the gear. The internal gear and the outer fixed ring are rotatably connected by a bearing. Except for the gear connected to the rotary motor, the other gears are rotatably connected to the side plates by bearings. The end of each gear is fixed with a plug. One of the gears is connected to the rotary motor. Side plates are fixed on both sides of the outer fixed ring, and the middle part of the side plates is fixed on the rotating shaft.

[0030] This invention uses a rotary motor to drive one of the gears to rotate, which in turn drives the internal gear to rotate, thereby causing the rack to reciprocate along the radial direction, thus controlling the insertion and exit of the plug core into the burst bead receiving cavity.

[0031] The longitudinal positioning glue spraying mechanism includes a fixing strip, and the bottom of the fixing strip is provided with a first glue gun that cooperates with the pop bead fixing roller. When the pop bead avoidance area is transformed into a rolling area, the first glue gun sprays glue on the upper knitted fabric. When it is the pop bead avoidance area, the first glue gun does not spray glue, so that the glue spraying area of ​​the first glue gun can be selected according to the number of columns of pop beads added.

[0032] The horizontal glue spraying mechanism includes a slide rail, and a second glue gun is provided in the sliding direction of the slide rail. By sliding the second glue gun on the slide rail, horizontal glue spraying can be performed, while avoiding the areas where popping beads need to be set.

[0033] Preferably, the softening impregnation device includes an impregnation tank, in which several impregnation rollers arranged in an S-shape are provided, which can impregnate the knitted fabric multiple times to soften it, ensuring greater comfort and softness in later use. The roller surface of the impregnation roller is provided with three partition plates along the axial direction, which can impregnate multiple knitted fabrics at one time, saving time.

[0034] In summary, the beneficial effects of this invention are as follows: 1. This invention softens the upper layer of knitted fabric using a softening impregnation device, followed by drying to reduce static electricity and increase softness. Then, burst beads are continuously sprinkled onto the center of a high-loft hot-air nonwoven fabric. Adhesive is then sprayed onto the upper surface of the upper knitted fabric, except at the location opposite the burst beads, ensuring no hot-melt adhesive is applied to the burst beads. This prevents the burst beads from becoming trapped and unable to burst later. The upper knitted fabric is then flipped so that its upper surface faces downwards, and together with the high-loft hot-air nonwoven fabric containing the burst beads, they are longitudinally rolled by a rolling mechanism. This seals the burst beads between the bottom high-loft hot-air nonwoven fabric layer and the upper knitted fabric, forming a composite knitted fabric containing burst beads. After drying and curing, a composite knitted fabric containing burst beads is produced, giving the knitted fabric more functions, such as antibacterial, fragrance, and moisturizing properties, meeting people's needs for functional textiles. The burst beads are firmly bonded to the knitted fabric, are not easily detached, and have a long service life.

[0035] 2. This invention, through the cooperation of the front rolling area, the rear rolling area, and the burst bead receiving cavity of the burst bead fixing roller, allows the upper knitted fabric after spraying glue and the high-loft nonwoven fabric with added burst beads to be laminated. Only the areas without burst beads are subjected to hot rolling lamination, while the areas with burst beads are not squeezed due to the annular grooves. This completes the sealing of the burst beads within the composite knitted fabric. At the same time, the transverse rolling plate can fix the burst beads within a square frame to prevent them from shifting.

[0036] 3. The present invention controls the insertion and exit of the plug core into the annular groove through a radial telescopic mechanism. When the top of the plug core extends to the opening of the annular groove, it cooperates with the annular gap filling silicone plate to form a rolling surface identical to the rolling zone. When the plug core is retracted into the through hole, a groove is formed, forming a burst bead avoidance zone. This can be used in conjunction with a separator plate, allowing the user to select the number of rows of burst beads to add.

[0037] 4. The softening impregnation device of the present invention includes an impregnation tank, wherein a plurality of impregnation rollers arranged in an S-shape are provided in the impregnation tank, which can impregnate the knitted fabric multiple times to soften it, ensuring that it is more comfortable and soft in later use.

[0041] The following specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. Those skilled in the art can make modifications to these embodiments without contributing any inventive step after reading this specification, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] Example

[0044] like Figure 16 As shown, a process for preparing a composite knitted fabric containing popping beads is characterized by including the following steps: S1, Softening and drying: The upper knitted fabric is softened by the softening impregnation device 9 and then dried. S2, continuously apply burst beads. The burst beads are positioned and quantitatively discharged by the positioning and quantitative discharge mechanism 1 of the burst bead adding device, and continuously sprinkle the burst beads onto the bottom layer of high-loft hot air nonwoven fabric to form three or more uninterrupted burst bead layers. The burst beads are sprinkled in a specific distribution pattern every 10cm in length onto the support structure layer made of high-loft hot air nonwoven fabric. S3, spray glue and flip, the upper knitted fabric is positioned and sprayed with glue by the positioning glue spraying mechanism 2, the position corresponding to the popping beads is not sprayed with glue, after spraying glue, flip it over and cover the high-loft hot air non-woven fabric containing popping beads. S4, Sealing the bursting beads: The high-loft hot air nonwoven fabric and knitted fabric containing bursting beads are heated and rolled by the rolling mechanism 3 to seal the bursting beads between the bottom high-loft hot air nonwoven fabric and knitted fabric, forming a composite knitted fabric. S5, Drying and curing: Drying and curing the composite knitted fabric with sealed popping beads.

[0045] Composite knitted fabric comprises: a knitted fabric layer and a fluffy hot-air nonwoven fabric layer; The recommended amount of popping beads is 1-100. The thickness of the fluffy nonwoven fabric is 5-50mm, and the weight is 10-60gsm. The weight of the upper knitted fabric is 10-35 gsm; Performance advantages of composite knitted fabrics 1. Unique functionality Slow-release function: The burst beads encapsulate various functional substances, such as antibacterial agents, fragrances, and moisturizers. These substances work continuously through the slow release of the burst beads, providing users with a long-term functional experience. For example, antibacterial burst beads can continuously release antibacterial ingredients, effectively inhibiting bacterial growth and keeping knitted fabrics clean and hygienic.

[0046] Targeted Functions: Depending on different needs, different functional substances can be encapsulated in the capsules to give the knitted fabric specific functions. For example, sports enthusiasts can choose capsules with moisture-wicking properties; those seeking comfortable sleep can choose aromatic capsules with calming and sleep-aiding functions.

[0047] 2. Good comfort Softness: Knitted fabrics are inherently soft, and the addition of popping beads does not affect their softness. On the contrary, the tiny size of the popping beads makes the knitted fabric feel more delicate to the touch, providing a comfortable feel.

[0048] Breathability: The structure of knitted fabric determines its excellent breathability, allowing air to circulate freely and keeping the skin dry. The presence of the burst beads does not hinder air circulation; on the contrary, their special structure may further enhance the breathability of the knitted fabric.

[0049] Elasticity: Knitted fabrics typically possess a certain degree of elasticity, allowing them to adapt to body movements and changes. The addition of beads does not affect the elasticity of the knitted fabric, making beaded knitted fabric more comfortable and free to wear.

[0050] 3. Durability Stability: The combination of the capsule beads and the knitted fabric is carefully designed to ensure the stability of the capsule beads during use. The capsule beads will not easily fall off or break, maintaining their functionality and aesthetics for a long time.

[0051] Washability: The burst bead knit fabric exhibits excellent washability; even after multiple washes, the function and appearance of the burst beads remain intact. This makes the burst bead knit fabric more convenient and practical for everyday use. like Figure 1 As shown, the popping bead adding device includes a frame 4. The frame 4 is provided with a positioning and quantitative dispensing mechanism 1 and a rolling mechanism 3 arranged sequentially from left to right. Above the rolling mechanism 3, there is a longitudinal positioning glue spraying mechanism 2 and a transverse glue spraying mechanism 20. The longitudinal positioning glue spraying mechanism 2 and the transverse glue spraying mechanism 20 are arranged in parallel. Below the longitudinal positioning glue spraying mechanism 2 and the transverse glue spraying mechanism 20, there are two parallel first guide rollers 21. On the left side of the rolling mechanism 3, there is a second guide roller 22 that flips the upper knitted fabric.

[0052] like Figure 2-6 As shown, the positioning and quantitative discharging mechanism 1 includes a storage hopper 41, a feeding pipe 42, a limiting cover 43, and a feeding roller 44 arranged sequentially from top to bottom on the frame 4. The limiting cover 43 has a cavity 431 inside. The side of the limiting cover 43 near the feeding roller 44 is formed with an arc-shaped limiting opening 439 to facilitate the rotation of the feeding roller 44. The roller surface of the feeding roller 44 has a plurality of popping bead discharge grooves 441 along the circumferential direction. The popping bead discharge grooves 441 are arranged in three or more groups along the axial direction of the feeding roller 44. The top of the limiting cover 43 has two or more through slots 436 along the length direction. A partition plate 432 that can be inserted into the through slot 436 is provided above the through slot 436. Limiting pieces 430 are fixed on both sides of the top of the partition plate 432.

[0053] like Figure 7-14As shown, the rolling mechanism 3 includes a heating roller 31 rotatably mounted on a frame and a pop-bead fixing roller 32. The pop-bead fixing roller 32 is positioned above the heating roller 31 and includes a hollow roller body 321. A rotating shaft 323 is fixed to the center of the roller body 321. The rotating shaft 323 is fixedly connected to the inner side of the roller body 321 via a support bar 329. The roller body 321 can be divided into a front rolling zone 341, a pop-bead avoidance zone 342, and a rear rolling zone 343 along the axial direction. The surface of the pop-bead avoidance zone 342 is circumferentially... An annular groove 322 is provided, and three or more annular grooves 322 are arranged in an axial direction. Several transverse rolling plates 326 are evenly distributed on the annular groove 322. The transverse rolling plates 326 and the roller body 321 form a burst bead receiving cavity 320. Several through holes 324 are provided at the bottom of the burst bead receiving cavity 320. Each through hole 324 is provided with a plug core 325. The inner side of each group of plug cores 325 in the annular groove 322 is connected to a radial telescopic mechanism 33. The plug cores 325 are radially telescopic within the burst bead receiving cavity 320 through the radial telescopic mechanism 33. The groove of the popping bead receiving cavity 320 is fixed with an annular gap-filling silicone plate 327. The radial telescopic mechanism 33 includes an inner fixing ring 331, an outer fixing ring 332, a rack 333, a gear 334, and an internal gear 335. The outer fixing ring 332 is located outside the inner fixing ring 331 and is concentric with it. A gear placement space 336 is formed between the outer fixing ring 332 and the inner fixing ring 331. Radial grooves 337 are formed in the radial direction of the outer fixing ring 332 and the inner fixing ring 331. The number of radial grooves is the same as that of the annular groove 322. The number of plug cores 325 in each set is the same. The rack 333 is slidably disposed in the radial groove 337. The gear 334 is disposed in the gear placement space 336 and meshes with the rack 333. The internal gear 335 is disposed on the inner side of the outer fixing ring 332 and meshes with the gear 334. The end of the rack 333 is fixed with the plug core 325. One of the gears 334 is connected to a rotary motor 330. Side plates 328 are fixed on both sides of the outer fixing ring 332. The middle part of the side plates 328 is fixed on the rotating shaft 323.

[0054] like Figure 15 As shown, the longitudinal positioning glue spraying mechanism 2 includes a fixing strip 211, and the bottom of the fixing strip is provided with a first glue gun 212 that cooperates with the popping bead fixing roller 32. The transverse glue spraying mechanism 20 includes a slide rail 201, and a second glue gun 202 is provided in the sliding direction of the slide rail.

[0055] like Figure 18As shown, the softening impregnation device 9 includes an impregnation tank 91, in which a plurality of impregnation rollers 92 arranged in an S-shape are provided, and the roller surface of the impregnation rollers 92 is provided with three partition plates 93 along the axial direction.

[0056] Working principle: such as Figure 1-18 As shown, when a row of popping beads is added, the partition plate 432 is inserted into the through groove. At the same time, the controller controls the rotary motor 330 to rotate, which in turn drives the rotary motor 330 of the radial telescopic mechanism 33 to rotate one of the gears 334, which in turn drives the internal gear 335 to rotate, which in turn drives the rack 333 to move outward in the radial direction until the top of the plug core 325 extends into the groove of the popping bead receiving cavity, and cooperates with the annular gap filling silicone plate to form the same rolling surface as the rolling zone. The controller controlling the motor is a very mature technology, so it will not be described in detail in this case. Then, the popping beads 403 are fed through the feeding pipe 42 into the limiting cover 43 via the storage hopper 41. They are then limited by the partition plates 432 in the area between the two partition plates 432. Excess popping beads 403 are scraped off by the limiting cover 43, and only the popping beads 403 that fall into the popping bead discharge groove 441 are continuously and evenly scattered onto the high-loft hot air nonwoven fabric 401 at the bottom. At the same time, the upper knitted fabric 402 is sprayed with glue on its upper surface by the glue spraying mechanism 2. No glue is sprayed at the position corresponding to the popping beads. After the glue is sprayed, the fabric is flipped over to cover the popping beads. In a high-loft hot-air nonwoven fabric layer containing popping beads, the bottom layer of high-loft hot-air nonwoven fabric 401 and the upper layer of knitted fabric 402 containing popping beads are rolled together by a rolling mechanism 3, sealing the popping beads between the bottom layer of high-loft hot-air nonwoven fabric and the upper layer of knitted fabric, forming a composite knitted fabric containing popping beads. The composite knitted fabric with the popping beads sealed in is then dried and cured, thus producing a composite knitted fabric containing popping beads. This gives the knitted fabric more functions, such as antibacterial, fragrance, and moisturizing properties, meeting people's needs for functional textiles. The popping beads are firmly bonded to the knitted fabric, do not easily fall off, and have a long service life.

[0057] To meet user needs, if more rows of popping beads are required, the controller simply controls the rotation of the partition motor 435, which in turn drives the rotation of the first gear 434, which in turn drives the rotation of the first rack 433, causing the partition plate 432 to move upward. This increases the range within which the popping beads 403 fall into the limiting cover 43. Simultaneously, the controller controls the rotation of the rotary motor 330, which in turn drives the rotation of the radial telescopic mechanism 33, which in turn drives one of the gears 334, which in turn drives the rotation of the internal gear 335, causing the rack 333 to move inward along the radial direction until the plug core 325 retracts into the through hole, forming a groove and creating a popping bead avoidance zone. When the popping bead avoidance zone 432 transforms into a rolling zone, the glue gun on the upper knitted fabric sprays glue. When it is the popping bead avoidance zone, the glue gun does not spray glue, thus cooperating with the partition plate and allowing the user to select the number of rows of popping beads to add.
