Description

Technical Field

[0001] This invention relates to the field of carpet technology, specifically to a flame-retardant, water-washable, quick-drying printed carpet and its preparation method. Background Technology

[0002] Carpets are a common indoor floor covering material, widely used in commercial and residential settings. They are typically made from natural fibers such as cotton, linen, wool, silk, and grass, or synthetic fibers, through hand or machine weaving, tufting, or spinning. Therefore, carpets without flame-retardant treatment are highly flammable and, once ignited, spread rapidly, posing a fire hazard. In severe cases, the thick smoke produced can cause injury or death, resulting in serious harm. Therefore, flame-retardant treatment of carpet products is essential to prevent carpet fires.

[0003] Currently, existing household carpets are mainly treated with flame retardant by adding flame retardant materials during the carpet manufacturing process or by treating the surface tufted layer with flame retardant. Although both methods have a certain flame retardant effect, they cannot prevent fires from spreading in the event of a large fire. Furthermore, the flame retardant materials and surface flame retardant treatment processes will cause some wear and tear with long-term use of the carpet, and the carpet cannot provide good flame retardant protection in the later stages of its use. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, this invention provides a flame-retardant, water-washable, quick-drying printed carpet and its preparation method. The carpet is divided into a base fabric structure, a flame-retardant structure, and a surface structure, thus enabling the carpet to be disassembled. The surface structure is further divided into multiple carpet modules, which are connected by interlocking letter-shaped fasteners. This facilitates washing and quick drying of the carpet. Furthermore, the modular design allows for partial replacement of damaged sections, reducing maintenance costs. The flame-retardant structure allows for the spraying of flame-retardant gas in the event of a fire, enabling timely extinguishing of the fire and preventing its further spread. The concealed design of the flame-retardant structure also prevents wear and tear from long-term use, thus addressing the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The first aspect of the technical solution: a flame-retardant water-washable quick-drying printed carpet, including a base fabric structure for serving as the bottom layer, a surface structure above the base fabric structure, and a flame-retardant structure for improving the flame-retardant effect of the product between the surface structure and the base fabric structure, wherein the flame-retardant structure is composed of a flame-retardant bladder and a release component.

[0007] The bottom fabric structure includes a bottom fabric body, with an edge material for covering the surface structure integrally sewn at the top edge of the bottom fabric body, and multiple receiving cavities for accommodating the flame-retardant bladder are opened on the top shell wall of the bottom fabric body.

[0008] The surface structure is composed of carpet modules and snap fasteners. The carpet modules include multiple modules that are linearly distributed laterally.

[0011] The receiving cavity is composed of circular grooves and straight grooves. There are multiple straight grooves distributed along the circumference of the edge of the circular grooves, and the circular grooves and straight grooves are connected. The ends of the multiple straight grooves away from the circular grooves are arc-shaped structures, and each straight groove has an embedded groove on the bottom fabric body at the arc-shaped structure.

[0012] As a further embodiment of the present invention, the carpet module includes a base layer for serving as a waterproof layer, an air channel is glued on the top of the base layer, a flame retardant layer is laid on the top of the air channel, a wear-resistant layer is woven on the top of the flame retardant layer, and a top pile layer is glued on the top of the wear-resistant layer, wherein the flame retardant layer and the base layer are bonded and fixed together by adhesive.

[0013] The top shell wall of the gas transmission channel is evenly provided with multiple jet holes for injecting flame-retardant gas. At the four corners of the bottom of the gas transmission channel, there are air inlets for the entry of flame-retardant gas. Directly below each air inlet, there is a hole located on the base layer, and an internal threaded ring is pressed into the hole.

[0014] As a further embodiment of the present invention, the plurality of the release components are movably connected to the corresponding internal threaded rings, and the cylindrical thread is connected to the inner wall of the internal threaded rings.

[0015] The destructive component includes a carrier that is bolted to the inner wall of a cylinder. There are two carriers, which are symmetrically arranged on the inner wall of the cylinder. A fixing frame is welded to the top shell wall of each carrier. A slider located on the carrier is slidably connected below the fixing frame. The slider has a through hole and a limiting hole, wherein the limiting hole is located on the side wall of the slider.

[0016] As a further embodiment of the present invention, a guide rod is fixedly connected to the top inner wall of the fixing frame, the bottom end of the guide rod passes through the through hole on the slider, and a reset spring located on the guide rod is sleeved between the fixing frame and the slider. A knife located on the side wall of the slider is installed below the limiting hole by bolts for piercing the gas-resistant bladder.

[0017] As a further embodiment of the present invention, a frame is bolted to the outer side wall of the carrier, and a circular hole and a through hole are provided on the side wall of the frame. There are two through holes, which are distributed on the front and rear sides of the circular hole. The bottom of the two sliders are connected by screws to a connecting plate for linkage.

[0018] As a further embodiment of the present invention, the limiting component includes a thermosensitive metal sheet disposed on the inner wall of the cylinder, the thermosensitive metal sheet being located directly above the two carriers, a double-sided wedge being installed on the bottom shell wall of the thermosensitive metal sheet, a single-sided wedge being slidably connected to both inclined surfaces of the double-sided wedge, and a round rod for guiding support and a spring telescopic rod for limiting the slider being fixedly connected to the side of the single-sided wedge away from the double-sided wedge, wherein there are two round rods, symmetrically distributed front and back, and the ends of the multiple round rods away from the single-sided wedges respectively pass through corresponding through holes and are fitted with limiting plates.

[0019] As a further embodiment of the present invention, the end of the spring telescopic rod away from the single-sided wedge passes through the corresponding circular hole and is inserted into the corresponding limiting hole for limiting.

[0020] As a further embodiment of the present invention, a fixing ring for serving as a pad is welded to the bottom outer ring of the cylinder, and the fixing ring is in contact with the inner groove.

[0021] The second technical solution: A method for preparing a flame-retardant, water-washable, quick-drying printed carpet, the method comprising the following steps:

[0022] Step 1: Fabrication of the base fabric structure. The base fabric body is formed by interlacing flame-retardant long filament polyester warp and weft yarns. The bottom of the base fabric body is glued with a rubber pad for waterproofing and anti-slip. Then, the edge material is sewn to the top edge of the base fabric body with thread. The inner wall of the edge material is sewn with a Velcro closure. Finally, the top of the base fabric body is stamped with a stamping device to form a cavity for accommodating objects.

[0023] Step 2: Surface Structure Construction. A waterproof base layer made of rubber is used as the subfloor. Gas channels for air passage are then glued to the top of the base layer. The top of the gas channels is covered with a flame-retardant layer. The bottom edge of the flame-retardant layer is glued to the top of the base layer. A wear-resistant layer for improved abrasion resistance is then woven on top of the flame-retardant layer. A top pile layer for improved comfort is glued to the top of the wear-resistant layer. This forms carpet modules for constructing the carpet. Multiple carpet modules are spliced ​​together using snap fasteners, and each carpet module has a sub-hook and loop fastener sewn along its top edge to accommodate the female hook and loop fastener.

[0024] The flame-retardant layer is woven from ground warp and weft yarns. The ground warp yarns are made of low-melting-point polyester fibers, while the weft yarns are made of flame-retardant fibers, including aramid 1313 fibers, aramid 1414 fibers, and polyimide fibers.

[0025] The wear-resistant layer is made of nylon fiber warp and nylon fiber weft interwoven;

[0026] Step 3: Assemble the release components. Sequentially load the limiting component and the breaking component into the inside of the cylinder, and use the limiting component to limit the breaking component.

[0027] Step 4: Assemble the carpet. Place each flame-retardant bladder into the corresponding cavity on the base fabric structure. Then, group the multiple release components into sets of four, each corresponding to a carpet module, and then thread them into the corresponding internal thread rings in each carpet module to assemble the release components on the surface structure.

[0028] Then, each carpet module with its release component assembled is laid on top of the backing fabric body in sequence, with the release component contacting the receiving cavity. The carpet modules are then spliced ​​together using snap fasteners. Finally, the edge material in the backing fabric structure is flipped up so that each female Velcro fastener is attached to the corresponding female Velcro fastener, thus assembling the carpet.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. By dividing the carpet into a base fabric structure, a flame-retardant structure, and a surface structure, the carpet can be disassembled. The surface structure is further divided into multiple carpet modules, which are spliced ​​together by letter snaps to facilitate washing and quick drying of the carpet.

[0031] 2. The splicing design of each carpet module in the surface structure allows for partial replacement of the carpet when it is damaged, avoiding the need to replace the entire carpet and thus reducing maintenance costs. Furthermore, the carpet modules are spliced ​​together by letter buckles and stably mounted on the backing structure by Velcro, making the finished product easy to assemble and disassemble, further reducing the manual burden during product maintenance.

[0032] 3. The flame-retardant structure allows for the spraying of flame-retardant gas in the event of a fire, thus extinguishing the fire promptly and preventing it from spreading further. Furthermore, the concealed design of the flame-retardant structure prevents wear and tear on the carpet over time, further ensuring its safety. Attached Figure Description

[0045] Please see Figure 1-2 In this embodiment of the invention, a flame-retardant, washable, quick-drying printed carpet includes a base fabric structure 1 serving as the bottom layer. A surface structure 2 is provided above the base fabric structure 1, and a flame-retardant structure for improving the flame-retardant effect of the product is provided between the surface structure 2 and the base fabric structure 1. By dividing the carpet into the base fabric structure 1, the surface structure 2, and the flame-retardant structure, a modular design is achieved. The flame-retardant structure enhances the flame-retardant effect of the carpet. This modular design not only facilitates washing and drying but also allows for partial replacement instead of complete replacement when a part of the structure is damaged, reducing maintenance costs. The flame-retardant structure consists of a flame-retardant bladder 3 and a release component 4. The flame-retardant bladder 3 is filled with flame-retardant gas. When the release component 4 punctures the flame-retardant bladder 3, the flame-retardant gas inside is released, extinguishing any fire on the carpet.

[0046] Please see Figure 1 and Figure 7 In this embodiment of the invention, the base fabric structure 1 includes a base fabric body 11. A rubber pad is provided at the bottom of the base fabric body 11 to improve the anti-slip effect of the carpet when placed on the ground, and the rubber pad also has a certain waterproof effect to prevent water stains from soaking the carpet and affecting its comfort. An edge material for covering the surface structure 2 is integrally sewn along the top edge of the base fabric body 11, and multiple receiving cavities 14 for accommodating the flame-retardant bag 3 are formed on the top shell wall of the base fabric body 11. A master Velcro fastener is sewn onto the inner wall of the edge material to improve the stability of the surface structure 2 when placed on the base fabric structure 1.

[0047] Please see Figure 3 , Figure 4 and Figure 8In this embodiment of the invention, the surface structure 2 is composed of carpet modules 21 and snap fasteners 22. There are three carpet modules 21 arranged linearly in the horizontal direction. Multiple carpet modules 21 are spliced ​​together using snap fasteners 22. Each carpet module 21 corresponds one-to-one with a multiple flame-retardant cushion 3. The number of carpet modules 21 corresponds to the number of flame-retardant cushions 3, thereby achieving a flame-retardant effect of a single flame-retardant cushion 3 on the corresponding carpet module 21. The snap fasteners 22 are composed of multiple snap fasteners arranged linearly in the vertical direction, ranging from three to nine; five are used in this embodiment. Sub-hook and hook fasteners are provided at the top edge of the carpet module 21.

[0048] Please see Figure 5 , Figure 6 and Figure 9 In this embodiment of the invention, the release component 4 comprises multiple components, arranged in groups of four, each corresponding to a specific flame-retardant bladder 3. Each release component 4 includes a cylinder 41 mounted on the carpet module 21. The cylinder 41 contains a puncture component for piercing the flame-retardant bladder 3 and a limiting component for preventing the puncture. The four release components 4 are mounted on the same carpet module 21, thereby enabling multi-directional fire monitoring of the carpet module 21 and further enhancing the fire monitoring effect.

[0049] Please see Figure 1 and Figure 7 In this embodiment of the invention, the edge material is composed of long strips 12 and short strips 13. Two long strips 12 are symmetrically arranged on the top outer wall of the base fabric body 11. Two short strips 13 are also symmetrically arranged on the top outer wall of the base fabric body 11. The edge material structure composed of the long strips 12 and short strips 13 can cover and wrap the edges of the surface structure 2 after it is placed on the base fabric structure 1. The combination of the female and female Velcro fasteners enhances the stability of the surface structure 2 mounted on the base fabric structure 1.

[0050] The receiving cavity 14 is composed of circular grooves and straight grooves. Multiple straight grooves are distributed circumferentially along the edges of the circular grooves, and the circular grooves and straight grooves are interconnected. The receiving cavity 14 is designed to accommodate the flame-retardant bag 3. The ends of the multiple straight grooves furthest from the circular grooves are arc-shaped, and each straight groove has an embedded groove on the base fabric body 11 at its arc-shaped end. The embedded groove is used to release the insertion of the component 4, thereby enabling the positioning and laying of each carpet module 21 in the surface structure 2 on the base fabric structure 1.

[0051] Please see Figure 3 , Figure 4 and Figure 8In this embodiment of the invention, the carpet module 21 includes a base layer 211 serving as a waterproof layer. An air delivery channel 212 is adhesively bonded to the top of the base layer 211, and a flame-retardant layer 213 is laid above the air delivery channel 212. A wear-resistant layer 214 is woven onto the top of the flame-retardant layer 213, and a top pile layer 215 is adhesively bonded to the top of the wear-resistant layer 214. The flame-retardant layer 213 and the base layer 211 are bonded and fixed together with adhesive. This bonding between the flame-retardant layer 213 and the base layer 211 further ensures the stability of the air delivery channel 212, and the air delivery channel 212 is made of soft rubber tubing material, thereby ensuring the comfort of walking on the carpet.

[0052] Multiple jet holes for injecting flame-retardant gas are evenly distributed on the top shell wall of the gas delivery channel 212. At the four corners of the bottom of the gas delivery channel 212, air inlets for the entry of flame-retardant gas are provided. Directly below each air inlet, a hole is located on the base layer 211, and an internally threaded ring 216 is press-fitted into the hole. The extensive arrangement of jet holes ensures a large-area release of flame-retardant gas to the carpet module 21, thereby improving the flame-retardant effect on the carpet module 21.

[0053] Please see Figure 5 , Figure 6 and Figure 9 In this embodiment of the invention, multiple release components 4 are movably connected to corresponding internal threaded rings 216, and a cylinder 41 is threadedly connected to the inner wall of the internal threaded ring 216. The ease of disassembly and assembly of the release components 4 within the internal threaded ring 216 further improves the ease of carpet assembly.

[0054] The destructive component includes a carrier 45 bolted to the inner wall of a cylinder 41. Two carriers 45 are symmetrically arranged on the inner wall of the cylinder 41. A mounting bracket 46 is welded to the top shell wall of each carrier 45, and a slider 47 is slidably connected to the lower part of the mounting bracket 46 on the carrier 45. The slider 47 has a through hole and a limiting hole, with the limiting hole located on the side wall of the slider 47. The sliding connection of the slider 47 to the carrier 45 ensures the stability of the slider 47 during displacement adjustment.

[0055] A guide rod 48 is fixedly connected to the top inner wall of the fixing frame 46. The bottom end of the guide rod 48 passes through the through hole on the slider 47, and a return spring located on the guide rod 48 is sleeved between the fixing frame 46 and the slider 47. The setting of the return spring allows the slider 47 to move downward quickly and forcefully after the limit is released.

[0056] A cutter 49 is bolted to the side wall of the slider 47 below the limiting hole, used to puncture the flame-retardant bladder 3. The cutter 49 mounted on the slider 47 moves synchronously as the slider 47 moves downward, thereby quickly puncturing the flame-retardant bladder 3 and ensuring the release of the flame-retardant gas inside the flame-retardant bladder 3.

[0057] A carrier frame 410 is bolted to the outer side wall of the carrier 45. The side wall of the carrier frame 410 has a circular hole and two through holes, located on the front and rear sides of the circular hole. A connecting plate 413 for linkage is screwed to the bottom of the two sliders 47. The connecting plate 413 allows for synchronous reset adjustment of the sliders 47 on both sides within the same release assembly 4.

[0058] The limiting component includes a thermosensitive metal sheet 42 disposed on the inner wall of the cylinder 41, positioned directly above the two carriers 45. The thermosensitive metal sheet 42 is positioned to more easily detect temperature changes on the carpet module 21. A double-sided wedge 43 is mounted on the bottom shell wall of the thermosensitive metal sheet 42, and a single-sided wedge 44 is slidably connected to both inclined surfaces of the double-sided wedge 43. A T-shaped slider is integrally provided on the inclined surface of the single-sided wedge 44, while a T-shaped track is provided on the inclined surface of the double-sided wedge 43 to accommodate the T-shaped slider, thereby ensuring the stability of the single-sided wedge 44's movement on the double-sided wedge 43.

[0059] A circular rod 411 for guidance and support and a spring telescopic rod 412 for limiting the slider 47 are fixedly connected to the side of the single-sided wedge 44 away from the double-sided wedge 43. There are two circular rods 411, symmetrically distributed front and back. The ends of the multiple circular rods 411 away from the single-sided wedge 44 pass through corresponding through holes and are fitted with limiting plates. The arrangement of the circular rods 411 ensures the stability of the single-sided wedge 44 as it moves with the double-sided wedge 43.

[0060] The end of the spring telescopic rod 412 away from the single-sided wedge 44 passes through the corresponding circular hole and is inserted into the corresponding limiting hole for limiting. The end of the spring telescopic rod 412 away from the single-sided wedge 44 is also rollably connected to a ball bearing. The ball bearing allows the spring telescopic rod 412 to continue rolling contact with the outer surface of the slider 47 after the limiting on the slider 47 is removed, thus facilitating the re-limiting of the slider 47 during subsequent reset and adjustment.

[0061] A retaining ring for acting as a pad is welded to the bottom outer ring of the cylinder 41, and the retaining ring contacts the inner groove. The cooperation between the retaining ring and the inner groove not only ensures the accuracy of the carpet modules 21 laid on the base fabric structure 1, but also further enhances the stability of the carpet modules 21 assembled on the base fabric structure 1.

[0062] The working principle of this invention is as follows: When the products are used in combination, the base fabric structure 1 is placed on the ground, and then multiple flame-retardant bags 3 are sequentially placed into the corresponding receiving cavities 14 opened on the base fabric structure 1. Then, multiple release components 4 are threaded onto the corresponding internal thread rings 216 with cylinders 41, thereby realizing the assembly of each release component 4 on the surface structure 2.

[0063] After each release component 4 is loaded, the carpet modules 21, each equipped with a release component 4, are sequentially arranged on the base fabric structure 1. During the laying process, the release components 4 mounted on the carpet modules 21 are aligned with the corresponding receiving cavities 14 opened on the base fabric structure 1. The precise arrangement of each carpet module 21 on the base fabric structure 1 is achieved by inserting the bottom end of the cylinder 41 in the release component 4 into the embedded groove in the corresponding receiving cavity 14.

[0064] After each carpet module 21 is laid on the base fabric structure 1, the carpet modules 21 are spliced ​​together by snap fasteners 22 to form a whole surface structure 2.

[0065] After the surface structure 2 is laid on the base fabric structure 1, the edge material with the mother hook and loop fastener sewn on the base fabric structure 1 is turned up, so that the long strips 12 and short strips 13 in the edge material, along with the mother hook and loop fastener, are attached to the carpet module 21 with the daughter hook and loop fastener sewn on, thereby realizing the overall combination between the surface structure 2 and the base fabric structure 1 to form a complete carpet.

[0066] When a fire occurs during carpet use, the materials of the top pile layer 215 and flame-retardant layer 213 in each carpet module 21 have a certain flame-retardant effect, which can control small fires to a minimum and prevent the carpet from burning. If the fire caused by the carpet is large, and the top pile layer 215 and flame-retardant layer 213 cannot retard the fire, the high temperature generated by the fire will cause the release components 4 located nearby in the corresponding carpet module 21 to be subjected to high temperatures.

[0067] When the release component 4 is subjected to high temperature, the heat-sensitive metal sheet 42 of the limiting component in its cylinder 41 moves due to the heat, which in turn drives the double-sided wedge 43 set on it to move downward. The movement of the double-sided wedge 43 causes the single-sided wedge 44 slidably connected to it to move, and then moves laterally under the support and guidance of the round rod 411, pulling the spring telescopic rod 412 to move, so that it is released from the limiting position of the slider 47 in the destruction component.

[0068] After the slider 47 disengages from its limit position, it moves linearly downwards along the guide rod 48 and the carrier 45 under the action of the return spring. During this downward movement, the slider 47 drives the tool 49 mounted on it and the connecting plate 413 to move downwards synchronously. The bottom end of the tool 49 is slightly longer than the connecting plate 413, allowing it to contact and puncture the corresponding gas-retardant bag 3 first. After the gas-retardant bag 3 is punctured, the downward pressure of the connecting plate 413 enlarges the opening, allowing the gas inside the gas-retardant bag 3 to escape quickly.

[0069] After the flame-retardant gas in the flame-retardant bladder 3 is discharged, it enters the gas supply channel 212 of the corresponding carpet module 21 in the surface structure 2 through the release component 4. The flame-retardant gas in the gas supply channel 212 is transported and released inside the gas supply channel 212, thereby realizing the rapid and large-scale release of flame-retardant gas to the corresponding carpet module 21, thus completing the rapid extinguishing of the fire in the carpet module 21 where a fire has occurred and preventing the fire on the carpet from spreading.

[0070] When the carpet needs to be cleaned, the assembly sequence of the various structures in the carpet is reversed to disassemble the carpet. The disassembled carpet can then be washed individually, which not only facilitates the washing process but also accelerates the drying process.

[0071] This invention proposes a method for preparing a flame-retardant, water-washable, quick-drying printed carpet, which includes the following steps:

[0072] Step 1: Fabrication of the base fabric structure 1. The base fabric body 11 is formed by interlacing flame-retardant filament polyester warp and weft threads. A waterproof and non-slip rubber pad is adhesively bonded to the bottom of the base fabric body 11, ensuring the safety of the carpet. Then, the edge fabric is sewn along the top edge of the base fabric body 11 with thread, and a Velcro closure is sewn onto the inner wall of the edge fabric. Finally, a receiving cavity 14 for accommodating objects is stamped into the top of the base fabric body 11 using a stamping device. The receiving cavity 14 is designed to accommodate and place the flame-retardant bag 3.

[0073] Step 2: Fabrication of surface structure 2, using a rubber base layer 211 as a waterproof underlayer. The waterproof effect of the rubber base layer 211 prevents water stains on the base fabric structure 1 from wetting the carpet module 21 in the surface structure 2.

[0074] Then, an air passage 212 for gas passage is adhesively bonded to the top of the base layer 211. The top of the air passage 212 is covered with a flame-retardant layer 213, the bottom edge of which is adhesively bonded to the top of the base layer 211. Next, an abrasion-resistant layer 214 for improved wear resistance is woven on top of the flame-retardant layer 213, and a top pile layer 215 for improved comfort is adhesively bonded to the top of the abrasion-resistant layer 214, thus forming a carpet module 21 for constructing the carpet. The top pile layer 215 is flame-retardant treated to further enhance the flame-retardant effect of the carpet. Multiple carpet modules 21 are spliced ​​together using snap fasteners 22, and each carpet module 21 has a sub-hook and loop fastener sewn along its top edge to mate with the female hook and loop fastener. The sub-hook and loop fasteners mate with the corresponding female hook and loop fasteners to ensure the assembly of the surface structure 2 onto the base fabric structure 1.

[0075] The flame-retardant layer 213 is woven from ground warp and weft yarns. The ground warp yarns are made of low-melting-point polyester fibers, while the weft yarns are made of flame-retardant fibers, including aramid 1313 fibers, aramid 1414 fibers, and polyimide fibers.

[0076] The wear-resistant layer 214 is made of nylon fiber warp and nylon fiber weft interwoven.

[0077] Step 3: Release the assembly of component 4. The limiting component and the breaking component are loaded into the inside of the cylinder 41 in sequence, and the breaking component is limited by the limiting component.

[0078] Step 4: Assemble the carpet. Place each flame-retardant bag 3 sequentially into its corresponding receiving cavity 14 on the base fabric structure 1. Then, group the multiple release components 4 into sets of four, each corresponding to a carpet module 21, and thread them sequentially into the corresponding internal thread rings 216 in each carpet module 21, thus assembling the release components 4 on the surface structure 2.
