Description

Technical Field

[0001] This invention relates to the field of fabric processing technology, and in particular to a textile fabric production equipment and process made of biomass nylon fiber, suitable for processing fibers and fabrics from bio-based nylon materials in today's society. Background Technology

[0002] Many existing clothing fabrics are now being processed using printing equipment, enabling the development of more personalized, three-dimensional, and complex clothing products. Of course, there are also many related fabric processing technologies, many of which are patented.

[0003] For example, Chinese Patent Application No. 201810731590.3 discloses a printer and a method for manufacturing flat fabric for clothing. The printer includes a mesh base plate, a first nozzle disposed above the mesh base plate for spraying fibers onto the mesh base plate to print flat fabric for clothing, and a hydroentangling device for hydroentangling the flat fabric on the mesh base plate through the mesh holes to make the fibers entangle.

[0004] For example, Chinese patent application number 201510041441.0 discloses a 3D printing device and implementation method for manufacturing woven fabric, which belongs to the field of FDM 3D printing and includes: a hot melt cavity, an extrusion pump, a long-distance arranged multi-hole nozzle, a rotary motor, a Z-axis lifting platform, and a cross-weaving method.

[0005] For example, Chinese patent application number 202110414035.X discloses a 3D printing device for wearing high-elasticity thermal fabric and its usage method. The printing device includes a fixing component, a worktable slidably mounted on the fixing component, a first hydraulic cylinder slidably mounted on the worktable, an adjusting component on the fixing component, a first printable component on the adjusting component, a second printable component on the adjusting component, and a feeding component on the fixing component. The first printable component includes a first printable body, a connecting frame rotatably mounted on the first printable body, and a driven wheel rotatably mounted on the connecting frame.

[0006] The existing equipment and processes generally suffer from two main problems: processing efficiency and structural stability and strength. These are areas that need improvement. Summary of the Invention

[0007] The purpose of this invention is to provide a production equipment and process for textile fabrics made from biomass nylon fibers with better processing results. It is applicable to the manufacture of fiber fabrics from bio-based nylon materials such as biomass nylon fiber PA56 in today's society.

[0008] The above-mentioned objective of the present invention is achieved through the following technical solution: a textile fabric production device made of biomass nylon fiber, comprising a printing substrate and a nozzle assembly capable of printing fibers on the printing substrate, the nozzle assembly comprising an X-axis nozzle capable of moving left and right and ejecting fibers in the front-back direction, a Y-axis nozzle capable of moving back and forth and ejecting fibers in the left and right direction, and a Z-axis nozzle capable of moving up and down and ejecting fibers downwards and with a limiting position, the Z-axis nozzle being capable of moving in three-dimensional space, the orifice diameter of the nozzles on the X-axis nozzle and the Y-axis nozzle being smaller than the orifice diameter of the nozzle on the Z-axis nozzle, and the ejection speed of the nozzles on the X-axis nozzle and the Y-axis nozzle being greater than the ejection speed of the nozzle on the Z-axis nozzle.

[0009] Among them, nylon fiber materials can utilize currently popular biomass fiber materials, especially bio-based nylon PA56, a new type of chemical fiber raw material, which can be melt-jet printed. Bio-based nylon PA56 is polymerized from bio-based pentanediamine and petroleum-based adipic acid. Pentanediamine is derived from the decarboxylation product of lysine and is synthesized using starch raw materials through a biological method, reducing greenhouse gas emissions and conserving petroleum resources. While PA56's mechanical properties are slightly lower than PA6, its moisture regain is significantly higher than nylon 6. PA56's saturated water absorption rate can reach 14%, higher than the 8% and 10% saturated water absorption rates of nylon 66 and nylon 6, respectively, improving its antistatic properties. The excellent moisture wicking rate greatly enhances wearing comfort. Nylon 56 has a lower glass transition temperature than nylon 66, making it neither brittle nor stiff when worn in high-altitude and cold regions, improving the material's low-temperature resistance. PA56 possesses high strength, heat resistance, and good moisture absorption, making it an ideal fiber fabric material.

[0010] As a preferred embodiment of the present invention, the X-axis nozzle is disposed on one of the front and rear sides of the printing substrate, and the Y-axis nozzle is disposed on one of the left and right sides of the printing substrate.

[0011] As a preferred embodiment of the present invention, the X-axis nozzle ejects X-axis fibers, the Y-axis nozzle ejects Y-axis fibers, and the fibers ejected by the Z-axis nozzle move on the printing substrate to form ZX-axis fibers and ZY-axis fibers.

[0012] As a preferred embodiment of the present invention, it further includes an X-axis gathering and pulling plate arranged relative to the spray direction of the X-axis nozzle and used to receive and pull one end of the X-axis fiber, and a Y-axis gathering and pulling plate arranged relative to the spray direction of the Y-axis nozzle and used to receive and pull one end of the Y-axis fiber.

[0014] As a preferred embodiment of the present invention, a front support rod that can be raised and lowered and supports the front portion of the X-axis fiber is provided on the front side of the printing substrate, a rear support rod that can be raised and lowered and supports the rear portion of the X-axis fiber is provided on the rear side of the printing substrate, a left support rod that can be raised and lowered and supports the left portion of the Y-axis fiber is provided on the left side of the printing substrate, and a right support rod that can be raised and lowered and supports the right portion of the Y-axis fiber is provided on the right side of the printing substrate. The front support rod, rear support rod, left support rod, and right support rod are all water-cooled rods, and the printing substrate is a water-cooled plate.

[0015] As a preferred embodiment of the present invention, a set of two front X-axis traction rollers are provided on the upper side of the front support rod, which are attached to each other and can work together with the front support rod to pull the front part of the X-axis fiber. A set of two rear X-axis traction rollers are provided on the upper side of the rear support rod, which are attached to each other and can work together with the rear support rod to pull the rear part of the X-axis fiber. A set of two left Y-axis traction rollers are provided on the upper side of the left support rod, which are attached to each other front to back and can work together with the left support rod to pull the left part of the Y-axis fiber. A set of two right Y-axis traction rollers are provided on the upper side of the right support rod, which are attached to each other front to back and can work together with the right support rod to pull the right part of the Y-axis fiber. The axial directions of the front and rear X-axis traction rollers are in the front-rear direction, and the axial directions of the left and right Y-axis traction rollers are in the left-right direction.

[0016] As a preferred embodiment of the present invention, the printing substrate is provided with X-axis guide pins arranged vertically for X-axis fiber jetting on the side portion of the X-axis nozzle, which are spaced apart from left to right; and the printing substrate is provided with Y-axis guide pins arranged vertically for Y-axis fiber jetting on the side portion of the Y-axis nozzle, which are spaced apart from front to back.

[0017] As a preferred embodiment of the present invention, the printing substrate is provided with water outlet holes for hydroentangling, and the upper front, left, rear and right positions of the printing substrate are all formed with arc transition surfaces.

[0018] A textile fabric production process using biomass nylon fiber, employing the aforementioned biomass nylon fiber textile fabric production equipment, includes the following steps: Step 1, spraying fibers downwards onto a printing substrate through a Z-axis nozzle to form ZX-axis fibers and ZY-axis fibers, the ZX-axis fibers and ZY-axis fibers interweaving to form at least one base fabric layer; Step 2, spraying fibers parallel to the printing substrate through X-axis nozzles and Y-axis nozzles to form X-axis fibers and Y-axis fibers, the X-axis fibers and Y-axis fibers interweaving to form at least one intermediate fabric layer; Step 3, spraying fibers downwards onto the printing substrate through a Z-axis nozzle to form ZX-axis fibers and ZY-axis fibers, the ZX-axis fibers and ZY-axis fibers interweaving to form at least one surface fabric layer, wherein the Z-axis nozzle is in a moving state when spraying fibers, while the X-axis nozzles and Y-axis nozzles are in a stationary state when spraying fibers.

[0019] The beneficial effects of this invention are: the design of this application can improve the printing and processing efficiency of fiber fabrics, improve the three-dimensionality, and increase the controllability of aesthetics.

[0020] The fabric structure design is more diverse, but the stability is better. More complex fabric structures can be designed, making it more personalized. It has greater commercial value for making samples or small batches of clothing.

[0021] Nylon fiber, also known as nylon, can be used as a clothing fabric material, specifically biomass nylon PA56. Nylon PA56 has a saturated water absorption rate of up to 14%, far exceeding that of polyester, and even higher than the saturated water absorption rates of nylon 66 and nylon 6 (8% and 10% respectively). It possesses excellent moisture-wicking and anti-static properties, significantly improving wearing comfort. Furthermore, PA56 has a density of 1.14 g / cm³. 3 Significantly lower than polyester's 1.4 g / cm³ 3 This can reduce the weight of corresponding clothing by 18%. Third, due to its asymmetrical structure of odd and even molecules, Nylon 56 has an extremely soft hand feel, approaching that of wool. As a textile fabric, it provides a very soft feel, greatly improving fabric quality. Fourth, Nylon 56 has a lower glass transition temperature than Nylon 66 and far lower than polyester. Using Nylon 56 in high-altitude and cold regions ensures that the fabric remains neither brittle nor stiff, significantly improving its low-temperature resistance. Fifth, as a biomass fiber, it has good skin-friendliness and biodegradability. Therefore, the development of biomass fiber PA56 as a textile fabric has excellent prospects and market potential. Using it in the equipment and processes described in this application will better realize its advantages.

[0022] Moreover, the biomass PA56 material has good dyeing ability and excellent dyeing effect, making it very suitable for fabric use. It also has advantages in dyeing efficiency and color fastness. Combined with the manufacturing equipment and process of this application, it has better market competitiveness in the field of modern fabrics and clothing. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0032] Example 1, such as Figure 1-7As shown, a textile fabric production device made of biomass nylon fiber includes a printing substrate 1 and a nozzle assembly capable of printing fibers on the printing substrate 1. The nozzle assembly includes an X-axis nozzle 2 that can move left and right and spray fibers in the front-back direction, a Y-axis nozzle 3 that can move back and forth and spray fibers in the left and right direction, and a Z-axis nozzle 4 that can move up and down and spray downwards. This is the most significant feature of this application. It not only has the traditional vertical scanning printing structure of the Z-axis nozzle 4, but the fiber spraying along the Z-axis is perpendicular to the printing substrate 1, and the spraying process of the Z-axis nozzle 4 needs to be formed during the movement process. In contrast, the X-axis nozzle 2 and Y-axis nozzle 3 spray parallel to the printing substrate 1. During the spraying process, the X-axis nozzle 2 and Y-axis nozzle 3 are stationary. This requires the X-axis nozzle 2 and Y-axis nozzle 3 to have sufficient spraying force. Of course, with such spraying force, the radial dimension of the fiber will be smaller, or thinner. Specifically, the Z-axis nozzle 4 can move in three-dimensional space. In this embodiment, the X-axis is the front-to-back direction, the Y-axis is the left-to-right direction, and the Z-axis is the up-to-down direction. The Z-axis nozzle 4 can be connected to an existing three-axis motor or a three-axis robotic arm or other mobile device. A mobile device with higher precision can be used. In this way, the Z-axis nozzle 4 can move in the XYZ axis directions. The X-axis nozzle 2 sprays fibers in the X-axis direction, but moves in the Y-axis direction. The Y-axis nozzle 3 does the opposite, spraying fibers in the Y-axis direction, but moving in the X-axis direction.

[0033] Furthermore, and importantly, the orifice diameters of the nozzles on the X-axis printhead 2 and Y-axis printhead 3 are smaller than those on the Z-axis printhead 4. The jetting speeds of the nozzles on the X-axis printhead 2 and Y-axis printhead 3 are greater than those on the Z-axis printhead 4. While the jetting speeds of the X-axis printhead 2 and Y-axis printhead 3 are the same (though they can vary depending on specific requirements), they must always be greater than the jetting speed of the nozzle on the Z-axis printhead 4. The Z-axis printhead 4 uses an FDM (Fused Deposition Modeling) printhead. Typically, one printhead corresponds to one central nozzle. The nozzle diameter is preferably between 0.2-0.5 mm, and the jetting speed is preferably 3-10 m / min. The final fiber diameter is also similar to the nozzle diameter, approximately 0.2 mm. This type of printhead is suitable for writing and scanning fiber printing. The jetting direction is perpendicular to the direction of fiber printing on the printing substrate 1. Because of the slow jetting speed and large diameter, the fiber itself has good strength, but the woven fabric will be relatively loose, resulting in insufficient fabric tension. Therefore, improvements are needed. This embodiment provides the design of X-axis nozzle 2 and Y-axis nozzle 3, forming different printing methods to improve existing shortcomings. X-axis nozzle 2 and Y-axis nozzle 3 need to have stronger jetting capabilities, but the diameter of the jetted fibers needs to be smaller, that is, finer. The nozzle size of the nozzles is controlled below 0.2 mm, the jetting speed is preferably 500-1500 m / min, and the fiber diameter is preferably below 0.1 mm, and preferably between 0.04-0.1 mm. The screw extrusion force alone is insufficient for this type of nozzle, so meltblown spinning can be used. The nozzle is typically used in melt spinning processes. Melt spinning involves melting polymer chips using a spinning screw extruder and extruding them in a measured quantity. Simultaneously, the melt is blown through the spinneret by a high-speed hot airflow to form fibers. This is essentially a spinning nozzle with a high-pressure hot airflow. However, in this embodiment, the nozzle orifice diameter can be slightly larger than that of most spinning nozzles, while the impact force of the high-pressure hot airflow can be slightly lower to meet the requirements of this embodiment. Therefore, the diameter of the extruded fiber will be slightly larger, preferably controlled between 0.04-0.1 mm, and not recommended to be lower than 0.02 mm, as excessively fine fibers have poor strength. Here, this nozzle needs to operate in an intermittent mode, which is suitable for small-batch, personalized production, or sample production. Of course, the fiber raw materials here are thermoplastic polymers, materials that can be heated to melt and cooled to solidify, which are also materials used in 3D printing equipment. The aforementioned nylon 56 and other raw materials are very suitable, and the dyeing effect is also good.

[0034] In addition, multiple Z-axis printheads 4 can be used, which not only improves efficiency but also allows for printing on fibers of different materials and colors. Similarly, multiple X-axis printheads 2 and Y-axis printheads 3 can also be used, further improving efficiency and enabling printing on fibers of different materials and colors. However, the difference lies in the mounting configuration: multiple Z-axis printheads 4 can be mounted on the same three-axis mechanical moving part's slide rail or robotic arm; multiple X-axis printheads 2 can be arranged horizontally and mounted on the same slider of a linear motor that can move horizontally (this can be called the first slider 71); and Y-axis printheads 3 can be arranged vertically and mounted on the same slider of a linear motor that can move vertically (this can be called the second slider 72). The printing base plate 1 is height-adjustable, and its bottom can be fixedly connected to a lifting device, such as a lifting motor, hydraulic cylinder, or pneumatic cylinder. Because printing involves a three-dimensional structure with vertical layers, the printing base plate 1 can gradually descend during printing to allow for layer-by-layer printing.

[0035] This design allows for the printing of more complex fiber fabrics with optimized structural performance. For example, the upper and lower layers of the fabric can be printed with coarse-sized interwoven fiber meshes using the Z-axis printhead 4, while the middle layers can be filled with multiple layers of fine-sized interwoven fiber meshes using the X-axis printhead 2 and Y-axis printhead 3. The linear density in the middle layer can be higher, and the tensile strength of the printed middle layer is better, supporting the entire fabric. Furthermore, the jetting speed in the middle layer is much faster, resulting in faster forming and improved efficiency. Of course, printing with interspersed coarse fibers is also possible, offering more printing methods and structural options. Color matching can also be more diverse; the coarse fibers output from the Z-axis can serve as the main color fibers, while the fine fibers output from the X and Y axes can be light-colored or transparent. Colors can be matched as needed, and these fibers can be dyed before printing, i.e., coloring is performed before or during the melting process of the polymer material. This results in smaller and more stable color differences during pre-printing dyeing. This allows for better control over fabric color. However, with this design, the printhead can only print one color of fiber. If you need to change colors, you must perform effective cleaning to avoid color mixing.

[0036] Preferably, the X-axis nozzle 2 is disposed on one of the front and rear sides of the printing substrate 1, and the Y-axis nozzle 3 is disposed on one of the left and right sides of the printing substrate 1. In this embodiment, for example, the X-axis nozzle 2 is disposed on the rear side of the printing substrate 1, and the Y-axis nozzle 3 is disposed on the right side of the printing substrate 1, and both are separated from the printing substrate 1.

[0037] Furthermore, it should be noted that the X-axis nozzle 2 ejects X-axis fibers parallel to the upper side of the printing substrate 1, and the Y-axis nozzle 3 ejects Y-axis fibers, also parallel to the upper side of the printing substrate 1. The fibers ejected by the Z-axis nozzle 4 move on the printing substrate 1 to form ZX-axis and ZY-axis fibers. The Z-axis nozzle 4 ejects fibers slowly downwards perpendicular to the printing substrate 1, and these fibers are formed by moving the Z-axis nozzle 4 in the forward / backward or left / right directions. The X-axis and Y-axis fibers are ejected at high speeds and have finer diameters, while the ZX-axis and ZY-axis fibers are ejected at slower speeds and have larger diameters.

[0038] Preferably, the production equipment in this embodiment further includes an X-axis gathering and pulling plate 20, which is set relative to the spray direction of the X-axis nozzle 2 and is used to receive and hold one end of the X-axis fiber, and a Y-axis gathering and pulling plate 30, which is set relative to the spray direction of the Y-axis nozzle 3 and is used to receive and hold one end of the Y-axis fiber. The X-axis nozzle 2, being on the rear side, sprays X-axis fibers forward, and the Y-axis nozzle 3, being on the right side, sprays Y-axis fibers to the left. The X-axis gathering and pulling plate 20, on the front side, receives the front end of the X-axis fiber, and the Y-axis gathering and pulling plate 30, on the left side, receives the left end of the Y-axis fiber. This ensures the fiber's tensile strength.

[0039] Furthermore, the X-axis gathering and pulling plate 20 can move back and forth, and the Y-axis gathering and pulling plate 30 can move left and right. The X-axis gathering and pulling plate 20 can be connected to a front-to-back telescopic cylinder or motor to achieve back-to-back movement, and the Y-axis gathering and pulling plate 30 can be connected to a left-to-right telescopic cylinder or motor to achieve left-to-right movement. An X-axis gel sheet 201 is connected to the side of the X-axis gathering and pulling plate 20 opposite to the X-axis nozzle 2, and a Y-axis gel sheet 301 is connected to the side of the Y-axis gathering and pulling plate 30 opposite to the Y-axis nozzle 3. The gel sheets help to adhere the fiber heads, facilitating collection and pulling, while the fiber tails are located near the nozzle or in contact with it. The X-axis focusing and pulling plate 20 is movable back and forth to facilitate adjustment and control of its distance from the X-axis nozzle 2, thereby controlling fiber length. Normally, the X-axis focusing and pulling plate 20 remains stationary during fiber spraying. However, if a slower spraying speed is selected for the X-axis nozzle 2, the X-axis focusing and pulling plate 20 needs to be moved closer to it. After spraying, once the fiber head touches the X-axis gel sheet 201, the X-axis focusing and pulling plate 20 immediately moves forward synchronously while the nozzle continues spraying, forming X-axis fibers by pulling the fibers. This provides more options for the work. Similarly, Y-axis fibers are collected and controlled by the Y-axis focusing and pulling plate 30.

[0040] Preferably, the printing substrate 1 has a front support rod 51 that can be raised and lowered to support the front part of the X-axis fiber, a rear support rod 52 that can be raised and lowered to support the rear part of the X-axis fiber, a left support rod 53 that can be raised and lowered to support the left part of the Y-axis fiber, and a right support rod 54 that can be raised and lowered to support the right part of the Y-axis fiber. After the X-axis fiber is printed, it will fall on the printing substrate 1. The front part of the X-axis fiber is supported on the front support rod 51 and the rear part is supported on the rear support rod 52. The front end of the X-axis fiber is on the X-axis gathering and pulling plate 20, and the rear end of the X-axis fiber is at the position of the X-axis nozzle. It can be understood that after one X-axis fiber is printed, the front support rod 51 is between the X-axis gathering and pulling plate 20 and the printing substrate 1, and the rear support rod 52 is between the printing substrate 1 and the X-axis nozzle 2. Similarly, the left support rod 53 is located between the Y-axis gathering and pulling plate 30 and the printing base plate 1, and the right support rod 54 is located between the printing base plate 1 and the right support rod 54. Each support rod can be raised or lowered by connecting to existing lifting equipment. Furthermore, the front support rod 51, rear support rod 52, left support rod 53, and right support rod 54 are all water-cooled rods, and the printing base plate 1 is a water-cooled plate. The water-cooling structure involves water-cooling pipes running through each structural component to cool and shape the fibers, as the ejected fibers are in a relatively hot and soft semi-molten state, requiring further cooling and solidification. All support rods extend horizontally.

[0041] Preferably, the upper side of the front support rod 51 is provided with a set of two front X-axis traction rollers 61 that are attached to each other and can work together with the front support rod 51 to pull the front part of the X-axis fiber. These two front X-axis traction rollers 61 can be installed and connected to the same roller bracket 8. The roller bracket 8 is connected to an existing three-axis or two-axis motor or other mobile equipment, which can at least realize lifting and lateral movement. In this way, the front X-axis traction rollers 61 work in conjunction with the front support rod 51 to better realize the post-processing of the X-axis fiber. When the printing of one X-axis fiber or multiple intermittent X-axis fibers at the same position is completed, the front part of these X-axis fibers will fall into the approximate triangular area formed by the two front X-axis traction rollers 61 and the upper side of the front X-axis traction rollers 61 and the front support rod 51. The front X-axis traction rollers 61 and the front support rod 51 descend together to pull the front part of the X-axis fiber down. On the one hand, the X-axis fiber is stretched into a relatively tight state. On the other hand, the head of the X-axis fiber can be pulled off the X-axis gathering traction plate 20 so as not to affect the printing of subsequent X-axis fibers. Of course, if some fiber materials are difficult to detach from the X-axis gathering and pulling plate 20, the X-axis gathering and pulling plate 20 can be moved forward during the downward pulling process of the front X-axis pulling roller 61 to achieve detachment. Alternatively, a blade capable of cutting fibers downward can be installed on the front side of the roller support 8 to achieve fiber end detachment. In addition, the downward pulling process of the front X-axis pulling roller 61 can also perform a kneading effect on multiple fibers, forming a better fiber bundle. Similarly, a set of two rear X-axis pulling rollers 62 are provided on the upper side of the rear support rod 52, which are left and right abutted and can work together with the rear support rod 52 to pull the rear part of the X-axis fiber. This is for processing and detaching the rear part of the X-axis fiber. The X-axis gel sheet 201 can be bonded to the X-axis gathering and pulling plate 20 and replaced periodically.

[0042] Similarly, a set of two left Y-axis traction rollers 63 are provided on the upper side of the left support rod 53, which are attached front to back and can work together with the left support rod 53 to lower and pull the left part of the Y-axis fiber. A set of two right Y-axis traction rollers 64 are provided on the upper side of the right support rod 54, which are attached front to back and can work together with the right support rod 54 to lower and pull the right part of the Y-axis fiber. This is a design for Y-axis fibers. The traction rollers can also be installed and connected to corresponding roller brackets for movement. The corresponding roller brackets are also connected to the moving equipment and can also be used to install blades and other structures. It should be noted that the axial directions of the front X-axis traction roller 61 and the rear X-axis traction roller 62 are in the front-rear direction, while the axial directions of the left Y-axis traction roller 63 and the right Y-axis traction roller 64 are in the left-right direction.

[0043] Preferably, the printing substrate 1 has vertically arranged X-axis guide pins 71 for spraying X-axis fibers, spaced apart on the side of the X-axis nozzle 2. Two adjacent X-axis guide pins 71 form a guide zone. The nozzle of the X-axis nozzle 2 sprays fibers into this guide zone. The spacing of the guide zone is preferably larger than the diameter of the nozzle of the X-axis nozzle 2. One guide zone can form a group of X-axis fibers. A group of X-axis fibers can consist of one or more fibers. In the case of multiple fibers, as long as the nozzle of the X-axis nozzle 2 intermittently sprays multiple X-axis fibers within this guide zone, and this guide zone corresponds to the area enclosed by the front and rear X-axis traction rollers and the front and rear support rods, it can be considered as a group of X-axis fibers at the same location. This makes the spraying position more precise and the guidance better. Similarly, the printing substrate 1 has vertically arranged Y-axis guide pins 72 for spraying Y-axis fibers, spaced apart on the side of the Y-axis nozzle 3. The X-axis guide pin 71 and the Y-axis guide pin 72 can be designed to be height-adjustable, for example, by mounting them on a height-adjustable plate and placing them around the periphery of the printing base plate 1 to achieve height adjustment.

[0044] Preferably, the printing substrate 1 has water outlet holes 10 for hydroentangling. Using existing hole-opening technology and connecting water pipes, water is sprayed through the water outlet holes 10 to perform hydroentangling. The fibers can be entangled through the hydroentangling process, resulting in better connection strength. This is existing technology and will not be elaborated here.

[0045] The printing substrate 1 has rounded transition surfaces 11 at the front, left, rear, and right positions on its upper side. This is to prevent fiber breakage at the side during fiber traction, and the rounded transition surfaces 11 improve the effectiveness of traction and facilitate the flow of water from the spunlace material out of the printing substrate 1. The fiber traction process also helps water flow out, and the outflowing water improves the cooling and shaping effect of the fiber. The rounded transition surfaces are similar to the rounded corner structures on many mechanical devices, but a 90-degree rounded corner is preferred here. This is because the extension length needs to be longer, and the degree of curvature is not uniform. A gentler curve with a gradual increase in curvature is required. For example, the rounded transition surface formed at the rear position on the upper side of the printing substrate 1 gradually transitions from the top to the rear and downward, with the curvature gradually increasing. This ensures that the upper side is flat as much as possible, with a larger curve at the side. Of course, the downward curvature should be very small, with the maximum depression not exceeding 0.5 mm. It should also be near the perimeter, otherwise it will affect the normal printing positioning of the main fibers of the fabric in the middle. The area of ​​a single arc transition surface should be less than one-fiftieth of the total surface area of ​​the printing base plate, and more than 90% of the entire area should be flat.

[0046] Of course, after the fabric is printed, the edges need to be trimmed or sewn with binding fabric to improve the aesthetics and integrity. This is a common fabric processing technique.

[0047] Regardless, the aforementioned equipment offers greater versatility and control over fabric printing, enabling the printing of a wider variety of fiber fabrics and more personalized and complex structural designs. It is well-suited for small-batch and sample production needs, offers better cost control, and can also serve as a reference for large-scale production.

[0048] Example 2: A production process for textile fabrics made from biomass nylon fibers. This example's production process is based on a textile fabric production equipment for biomass nylon fibers described in Example 1. It requires the use of the biomass nylon fiber production equipment from Example 1 and specifically includes the following steps:

[0049] Step 1: Fibers are ejected downwards from the Z-axis nozzle 4 directly onto the printing substrate 1, forming ZX-axis and ZY-axis fibers. These fibers interweave to form at least one base fabric layer. In this step, the Z-axis nozzle 4 moves along either the X-axis or Y-axis while ejecting the fibers, thus forming ZX-axis or ZY-axis fibers. These ZX-axis and ZY-axis fibers serve as the main fibers, forming the fabric framework. The ZX-axis and ZY-axis fibers are relatively coarse. After the ZX-axis and ZY-axis fibers interweave to form a base fabric layer, the printing substrate 1 needs to descend a certain distance to facilitate printing the upper fiber fabric layer. The ejection speed of the ZX-axis and ZY-axis fibers is controlled at 3-10 meters per minute, and the diameter is controlled at 0.1-0.3 millimeters. Generally, one base fabric layer is sufficient. Here, one Z-axis nozzle 4 can be used to print ZX-axis fibers and ZY-axis fibers one by one, or two Z-axis nozzles 4 can be used together to print ZX-axis fibers and ZY-axis fibers to improve efficiency. They can be in the same direction or in a cross direction. When they are in a cross direction, care should be taken to avoid them.

[0050] Step 2: Fibers are ejected parallel to the printing substrate 1 through X-axis nozzle 2 and Y-axis nozzle 3 to form X-axis and Y-axis fibers. These fibers interweave to form at least one intermediate fabric layer, which is printed on top of the base fabric layer. During printing, the nozzles of the nozzles need to be higher than the already printed fabric structure layer, and the ejection direction should be parallel to the printing substrate 1. The ejection speed is controlled at 500-1500 m / min, and the fiber diameter is controlled to be below 0.1 mm, preferably between 0.04-0.1 mm. This step is used for rapid processing of fine fibers. The X-axis and Y-axis fibers interweave to form the intermediate fabric layer, which can be multi-layered to ensure tensile strength. X-axis nozzle 2 and Y-axis nozzle 3 can be used alternately. During printing, the nozzles can be about 1 mm higher than the already printed fabric structure layer. After being ejected and flying through the air, the X-axis and Y-axis fibers will eventually sink onto the already printed fabric structure layer due to gravity and their flexibility. The fibers at each location on the middle fabric layer don't need to be single strands. Because the fibers here are relatively fine, multiple X-axis or Y-axis fibers can be printed at each location, forming a fiber bundle. Furthermore, since the number of fiber bundles is relatively small, the breathability is better. Multiple X-axis printheads 2 and multiple Y-axis printheads 3 can also be used, allowing multiple printheads at different locations in the same direction to spray fibers simultaneously, improving efficiency and enabling intermittent spraying of multiple fibers. After one group of fibers has been printed, the X-axis printheads 2 and Y-axis printheads 3 can be moved to another location for printing.

[0051] Step 3: The Z-axis nozzle 4 sprays fibers downwards directly onto the printing substrate 1 to form ZX-axis fibers and ZY-axis fibers. The ZX-axis fibers and ZY-axis fibers interweave to form at least one surface fabric layer. The processing in step 3 is similar to that in step 1, but the surface fabric layer is printed on the upper side of the intermediate fabric layer.

[0052] This printing method creates a more three-dimensional fiber fabric, improving efficiency and structural stability.

[0053] Among them, the Z-axis nozzle 4 is in a moving state when spraying fibers, while the X-axis nozzle 2 and Y-axis nozzle 3 are in a stationary state when spraying fibers.

[0054] Before step 1, the fiber raw materials can be pre-dyed, allowing for the printing of fibers in different colors as needed. This provides greater personalization, reduces subsequent dyeing processes, makes costs more controllable, and is more environmentally friendly; at most, it involves replacing or cleaning the printhead. Of course, dyeing can also be done after the fabric processing is complete, especially when using the aforementioned biomass nylon material, where the dyeing effect is still quite good.

[0055] In step 2, during the printing of the intermediate fabric layer, the printing of ZX-axis fibers and ZY-axis fibers can be mixed and interwoven to form a filling structure with special textures or structures. The structure is also a three-dimensional and personalized embodiment, and fabrics with different colors and patterns can be printed.

[0056] In addition, during the printing of X-axis and Y-axis fibers, after printing a fiber or a group of fibers at each position, the front and rear ends are immediately pulled downwards to make the fibers taut and tidy up, and the head is broken off, so as not to affect the printing of subsequent fibers.

[0057] The above-mentioned production process uses an upper, middle, and lower covering structure, which is a relatively regular structure, but it can also print more personalized and complex structures, and the structural stability is also good.

[0058] Of course, due to the special nature of the equipment, the production process is not limited to the above. Different methods and timings can be chosen to mix and print ZX-axis fibers, ZY-axis fibers, X-axis fibers, and Y-axis fibers, forming unique three-dimensional fabric structures. This method is also more efficient than traditional equipment. The combination of coarse and fine fibers, different colors, etc., results in superior three-dimensionality and visual appeal, making it very suitable for modern aesthetic and processing needs. Overall cost control is also better, material waste is less, and it is relatively more environmentally friendly. Compared to traditional production processes, 3D printing can produce prototypes much faster, saving manufacturing cycles and costs. It has significant advantages such as personalized customization, complex structures and geometries, rapid prototyping, reduced material waste, and innovative design.
