Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fiber cloth, in particular to a continuous tearable fiber cloth with embossed color assignment and a preparation device. BACKGROUND

[0002] Superfine fiber towels have become widely used textiles in the field of daily cleaning and personal care due to their excellent water absorption, softness and durability. In order to enhance product recognition and brand value, it is often necessary to print trademarks, corporate logos or specific patterns on the surface of the towel. Currently, the industry mainly adopts two types of printing technologies, including direct printing and heat transfer printing.

[0003] Direct printing process usually applies pigments or dyes directly to the surface of the fabric, which is simple to operate and has bright colors, but the pattern is often attached to the surface of the loop. Due to the presence of the three-dimensional loop structure on the surface of the superfine fiber towel, the actual presentation of the pattern after printing is largely affected by the arrangement state of the loop. During daily use and repeated washing, the loop is prone to lodging, entanglement or local collapse, resulting in blurred pattern outline, uneven color and significantly reduced visual effect. This problem is particularly prominent in the printing of patterns of the same color or similar color - when the pattern color is similar to the towel body color, the pattern is almost indistinguishable due to the lack of sufficient contrast, which severely restricts the design flexibility and product expressiveness.

[0004] To improve the firmness and clarity of the pattern, heat transfer printing technology has emerged, which transfers the pattern on the transfer film to the fabric through heating and pressing. In the prior art, there are also process schemes combining ironing and transfer printing.

[0005] The patent document with the application publication number CN119265969A discloses a printed superfine fiber towel and a preparation method thereof. Each towel unit has a heat-shrunk recessed area and a printed pattern transferred in the heat-shrunk recessed area. The preparation method includes contacting the printing mark roll paper with the heat press die and pressing the towel fabric, the temperature of the heat press die is conducted to the towel fabric through the printing mark roll paper, the upper loop of the towel fabric is heated and shrunk, the printing mark is transferred to the heat-shrunk recessed area, the heat press die is raised, the heat-shrunk recessed area is formed on the towel fabric consistent with the heat press die, the loop in the heat-shrunk recessed area is laid flat and the color difference is formed between the heat-shrunk recessed area and the area not subjected to heat shrinkage; the surface temperature of the heat press die is 215-220 degrees, and the contact time of the heat press die with the towel fabric is 2.5-5 seconds.

[0006] The method disclosed in the above patent document enhances the adhesion and visibility of the pattern to a certain extent, but still has some inherent problems: first, the process is highly dependent on the substrate quality and printing accuracy of the transfer paper. If the transfer paper itself has uneven stretching or printing registration deviation, it is easy to cause misalignment between the transferred pattern and the preset heat pressing concave area. Second, in order to compensate for this potential positional deviation, the production is often forced to expand the area of the heat pressing area, making it larger than the actual pattern required range. This approach not only causes waste of heat energy and materials, but also may affect the overall appearance and hand consistency of the towel due to the excessive size or inaccurate position of the heat pressing area, making it difficult to ensure stable yield in continuous mass production. In addition, if the heat pressing temperature or time is not properly controlled, it may also damage the fiber structure and affect the water absorption and softness of the towel.

[0007] Therefore, the existing technology still faces the following core challenges: how to achieve high-definition and high-fastness transfer printing of patterns on superfine fiber towels; how to overcome the misalignment of patterns caused by material and alignment problems during the transfer process; and how to maintain process stability and product consistency in continuous production while avoiding negative impacts on the water absorption and touch performance of the towel itself. Developing an printing process that can accurately align, adapt to the same color printing, and have less impact on the performance of the fabric body has become a technical problem that needs to be solved in the field. SUMMARY

[0008] The technical problem solved by the present application is to provide a continuous tearable fiber cloth with embossed and colored patterns and a preparation device.

[0009] The technical solution adopted by the present application to solve the above technical problem is: a continuous tearable fiber cloth with embossed and colored patterns, comprising a long-width fiber cloth with a strip-shaped tear line penetrating the width, the strip-shaped tear line spacing the long-width fiber cloth into a plurality of cloth units, the long-width fiber cloth comprising a base layer, a terry layer on the surface of the base layer, and a composite pattern formed on the surface of the cloth unit, the composite pattern comprising a three-dimensional concave-convex part and a colored layer, the terry layer being adhered to the base layer after the terry layer is hot-pressed and melted and laid down in the concave position of the concave-convex part, the colored layer being formed by silk-screen transfer printing and completely covering or selectively filling the surface of the concave position of the concave-convex part, the outline of the colored layer being spatially adapted to the surface outline of the concave position.

[0013] The preferred technical scheme adopted by the present application to solve the above technical problem is that the recessed position of the concave-convex part is formed to a depth of 30-80% of the original height of the terry layer.

[0014] The preferred technical scheme adopted by the present application to solve the above technical problem is that the concave-convex part is formed by a process with a hot-pressing temperature of 220-250 DEG C and a pressure of 0.5-3.0 MPa.

[0015] The preferred technical scheme adopted by the present application to solve the above technical problem is that a preparation device of a continuous tearable fiber cloth with embossed and colored patterns comprises a cloth conveying frame, a tear line preparation module and an embossed and colored pattern preparation module.

[0016] The embossed and colored pattern preparation module comprises a self-adaptive printing platform for supporting under the fiber cloth, a composite die assembly, a squeegee system assembly and a cloth pressing module.

[0017] The cloth pressing module is used to press the part of the fiber cloth on the cloth conveying frame that needs to be embossed and colored on the self-adaptive printing platform.

[0018] The composite die assembly comprises a fixed support, an integrated plate, a movable plate and a hot-pressing and shaping die and a silk-screen printing die assembled under the movable plate.

[0019] The fixed support is installed on the device frame and can move back and forth relative to the self-adaptive printing platform.

[0020] The integrated plate is provided on the fixed support by a lifting driving part and can move up and down relative to the self-adaptive printing platform.

[0021] The movable plate is provided under the integrated plate by a horizontal driving part and can move left and right relative to the self-adaptive printing platform.

[0022] The integrated plate is pressed down to make the silk-screen printing die dip and scrape the ink of the squeegee system assembly.

[0023] The fixed support is moved forward, the integrated plate is pressed down again to make the hot-pressing and shaping die hot-press the fiber cloth on the self-adaptive printing platform to prepare the concave-convex part.

[0024] The integrated plate is lifted, the movable plate is horizontally moved to make the silk-screen printing die align with the concave-convex part.

[0025] The integrated plate is pressed down to make the silk-screen printing die hot-press and color the concave-convex part.

[0026] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the fabric pressing module is integrated on the integrated plate, the fabric pressing module includes a pressing frame that matches the adaptive printing platform and a plurality of guide posts that connect the pressing frame to the integrated plate, and the guide posts are fitted with springs that abut against the integrated plate and the pressing frame.

[0027] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the hot pressing molding die head includes a first rectangular template and a raised mold body integrally formed below the first rectangular template; the screen printing coloring die head includes a second rectangular template and a plastic mold installed below the second rectangular template;

[0028] The four sides of the pressing frame are equipped with paired through-beam distance sensors between the four sides of the first rectangular template and the four sides of the second rectangular template.

[0029] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problem is: the lower surface area of ​​the raised mold body is smaller than the area of ​​the ink pattern transferred from the mold by the printing system assembly.

[0030] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the adaptive printing platform includes a base, a first slide, a second slide, and a support platform fixed on the second slide; the first slide moves back and forth relative to the base, and the second slide moves left and right relative to the first slide.

[0031] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the support platform includes a high-temperature resistant glass support plate and an image detection module located below the high-temperature resistant glass support plate;

[0032] The image detection module captures the lower surfaces of the hot-pressing molding head and the screen-printing color-applying head that have moved above the high-temperature resistant glass support plate to detect the positional matching of the hot-pressing molding head and the screen-printing color-applying head.

[0033] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the adaptive printing platform is provided with a roller shaft with a height lower than that of the high-temperature resistant glass support plate on the side near the screen printing color-applying die head, so that the fiber cloth is inclined.

[0034] Compared with existing technologies, the advantages of this invention are: first, the loop layer is formed into a three-dimensional shape with a concave-convex structure through hot pressing; then, the colored pattern is precisely applied to the concave areas of the concave-convex structure through screen printing transfer printing. Here, the loops are pressed down by hot pressing, making them easier to color, and the concave structure provides a certain degree of physical protection for the printed layer, making it less susceptible to direct wear during daily wiping, significantly improving the durability of the pattern. Because the colored layer and the concave-convex area are perfectly matched in three-dimensional space, problems such as pattern misalignment, stretching, or breakage that easily occur when flat printing is applied to a three-dimensional surface are effectively avoided. This process not only ensures the consistency of the pattern on each fabric unit, but also, with the help of the fast-drying components added to the screen printing ink and the auxiliary curing effect of the subsequent hot pressing process, further improves the drying speed and color fastness of the pattern, achieving instant drying, which is particularly suitable for continuous and efficient production.

[0045] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0046] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

Therefore, they should not be construed as limitations on this invention. Similarly, "first" and "second" are only for ease of understanding and have no other directional meaning, and should not be considered as limitations on this invention.

[0048] like Figures 1-2 As shown, this embodiment provides a preparation device for a continuous tearable fiber cloth with embossing and coloring, including a cloth conveyor frame 1, a tear line preparation module 2, and an embossing and coloring preparation module 3. The embossing and coloring preparation module 3 includes an adaptive printing platform 4 for supporting the fiber cloth, a composite die head assembly 5, a squeegee system assembly 6, and a cloth holding module 7. The cloth holding module 7 is used to hold the part of the fiber cloth on the cloth conveyor frame 1 that needs to be embossed and colored onto the adaptive printing platform 4. The squeegee system assembly 6 includes an ink storage box 8, a screen printing plate 9, a squeegee 10, a return ink blade 11, and a blade driving mechanism 12.

[0049] like Figure 3 As shown, the composite mold head assembly 5 includes a fixed bracket 13, an integrated plate 14, a movable plate 15, and a hot pressing molding mold head 16 and a screen printing coloring mold head 17 assembled below the movable plate 15; the fixed bracket 13 is installed on the equipment frame and can move back and forth along the adaptive printing platform 4; the integrated plate 14 is mounted on the fixed bracket 13 through a lifting drive component and can move up and down relative to the adaptive printing platform 4; the movable plate 15 is located below the integrated plate 14 through a transverse drive component and can move left and right relative to the adaptive printing platform 4.

[0050] The equipment's workflow is as follows: Fabric conveyor frame 1 conveys fiber fabric. In each cycle, tear line preparation module 2 and embossing and coloring preparation module 3 prepare tear lines and patterns at different positions on the fiber fabric, respectively. Fabric conveyor frame 1 conveys fiber fabric downstream, and then tear line preparation module 2 and embossing and coloring preparation module 3 repeat the operation in the next cycle.

[0051] like Figures 4-6 The working method of the printing and coloring preparation module 3 is as follows: the integrated plate 14 first presses down to make the screen printing and coloring die head 17 dip into the ink of the squeegee system assembly 6; then the fixed bracket 13 moves forward, and the integrated plate 14 presses down again to make the hot pressing and shaping die head 16 hot press the fiber cloth on the adaptive printing platform 4 to prepare the concave and convex parts 19; then the integrated plate 14 rises, and the movable plate 15 moves laterally to make the screen printing and coloring die head 17 align with the concave and convex parts 19; finally, the integrated plate 14 presses down to make the screen printing and coloring die head 17 hot press and color the concave and convex parts 19.

[0052] like Figure 8 As shown, a continuous tearable fiber fabric with embossed color is prepared using the above-described equipment. This fiber fabric includes a long fiber fabric 18 with a through-width stripe tear line 20, which divides the long fiber fabric into multiple fabric units. The long fiber fabric 18 includes a base layer 19, a loop layer on the surface of the base layer, and a composite pattern 40 formed on the surface of the fabric units. The composite pattern 40 includes three-dimensional raised and recessed portions 19 and a colored layer 41. In the recesses of the raised and recessed portions 19, the loops of the loop layer are hot-pressed, melted, and flattened, adhering to the base layer 19. The colored layer is formed by screen transfer printing and completely covers or selectively fills the surface of the recesses of the raised and recessed portions 19. The outline of the colored layer spatially matches the surface outline of the recesses. Preferably, the stripe tear line 20 is any one or a combination of multiple forms selected from hot-melt indentation lines, dashed perforated lines, or laser-weakened lines.

[0053] The aforementioned equipment integrates the two key processes of hot pressing and screen printing into a single module, and achieves fully automated operation through program control, significantly improving production efficiency while avoiding errors and time losses caused by material handling and alignment between multiple machines. Since both hot pressing and screen printing are completed in the same location on the fabric in a near-continuous state, and the two die heads controlled by the same drive system operate sequentially, the fabric is firmly held on the printing platform without displacement during processing. This greatly helps solve the alignment problem of matching contours in space, which is difficult to achieve when processing separately.

[0054] The process employs a "shaping first, then coloring" sequence. First, the terry loop layer is hot-pressed to form a three-dimensional shape with a raised and recessed structure. Then, the colored pattern is precisely applied to the recessed areas of the raised and recessed parts 19 using screen printing transfer printing. Because the terry loops in the recessed areas melt and flatten after hot pressing, adhering to the base layer 19, the screen-printed ink is more easily colored onto its surface. Furthermore, during washing, no terry loops will escape from this area, avoiding the problem of a messy pattern after washing.

[0055] Because the colored layer and the raised / recessed portion 19 are perfectly matched in three-dimensional space, problems such as pattern misalignment, stretching, or breakage that easily occur when flat printing is applied to three-dimensional surfaces are effectively avoided. This process not only ensures the consistency of the pattern on each fabric unit, but also, with the help of the fast-drying components added to the screen printing ink and the auxiliary curing effect of the subsequent hot pressing process, further improves the drying speed and color fastness of the pattern, achieving instant drying, which is particularly suitable for continuous and efficient production.

[0056] like Figure 8 As shown, the three-dimensional raised / recessed portion 19 includes, as well as at least one of recessed areas, raised areas, and sloping areas. That is, the simplest raised / recessed portion 19 can be composed of a recessed area and its surrounding unpressed, relatively raised original loops; more complex forms include a distinctly raised portion and a sloping transition portion connecting the recess and the raised portion. The colored layer is located in the recessed area, which not only makes the loops easier to color due to the heat pressing, but also provides a certain degree of physical protection for the printed layer, making it less susceptible to direct wear during daily wiping and significantly improving the durability of the pattern.

[0057] like Figures 3-6 As shown, the fabric holding module 7 is integrated onto the integrated plate 14. The fabric holding module 7 includes a holding frame 21 that matches the adaptive printing platform 4 and several guide posts 22 connecting the holding frame 21 to the integrated plate 14. Springs 23 are fitted onto the guide posts 22, abutting against the integrated plate 14 and the holding frame 21. Integrating the holding module onto the movable integrated plate 14 allows it to move synchronously with the die head. When the integrated plate 14 presses down, the holding frame 21 first contacts the fabric and presses it firmly onto the printing platform. Subsequently, the springs 23 are compressed, and the integrated plate 14 continues to descend, driving the die head to perform the operation. This design ensures that the fabric remains flat and fixed throughout the hot pressing and screen printing process. The springs 23 provide cushioning, preventing damage from the rigid impact of the holding frame 21 on the fabric surface, while also adapting to slight thickness variations in the fabric to ensure uniform pressure, which is especially important for terry cloth.

[0058] like Figures 4-6As shown, the hot-press molding die 16 includes a first rectangular template 24 and a raised molded body 25 integrally formed below the first rectangular template 24. The screen printing and coloring die 17 includes a second rectangular template 26 and a plastic mold 27 installed below the second rectangular template 26. Paired through-beam distance sensors are provided between the four sides of the holding frame 21 and the four sides of the first rectangular template 24 and the second rectangular template 26. The through-beam distance sensors can monitor the relative positional relationship between the holding frame 21 and the edges of the two die templates in real time. During the lateral movement of the movable plate 15 when switching between the hot-press molding die 16 and the screen printing and coloring die 17, the sensors provide real-time feedback to ensure that the screen printing die can move precisely to a position that completely overlaps with the previous hot-press molding area.

[0059] Preferably, the lower surface area of ​​the raised molded body 25 is smaller than the area of ​​the ink pattern transferred from the squeegee system assembly 6 by the mold 27. This is because high-temperature hot stamping of polyester fibers will slightly overflow. If the projected area of ​​the raised portion 19 formed by hot pressing is larger than the ink pattern, the edges of the raised portion 19 may not be completely covered by the ink, resulting in white gaps. Conversely, making the area of ​​the ink pattern slightly larger than the projected area of ​​the raised portion 19 ensures that the ink can completely cover the entire three-dimensional structure, including its edges and slopes, thereby obtaining a complete pattern with rich colors and clear boundaries, avoiding the production of defective products. This is a further refinement of the process to ensure that the spatial compatibility requirements are met during the overprinting process.

[0060] Preferably, such as Figure 8 As shown, the recessed depth of the raised portion 19 is 30%-80% of the original height of the terry cloth layer. The raised portion 19 is formed by a hot-pressing process at a temperature of 220-250℃ and a pressure of 0.5-3.0MPa. This depth ensures that the recess has sufficient depth to create a distinct three-dimensional visual effect and effective structural protection, avoiding the limited protective effect of a shallow depth on the layer. At the same time, retaining at least 20% of the original terry cloth height is to avoid completely compressing the terry cloth into a dense, hard sheet-like structure. Retaining some fluffy terry cloth fibers maintains the basic absorbency and soft touch of this area, preventing the cloth from becoming stiff and less absorbent due to excessive hot pressing, thus affecting the overall performance. This parameter range is an optimized range obtained after balancing aesthetics and practicality.

[0061] like Figure 7 As shown, the adaptive printing platform 4 includes a base 28, a first slide 29, a second slide 30, and a support platform 31 fixed on the second slide 30. The first slide 29 moves back and forth relative to the base 28, and the second slide 30 moves left and right relative to the first slide 29. This platform is not fixed, but can be finely adjusted in two dimensions, back and forth and left and right, in the horizontal plane, allowing users to adjust its position according to their needs.

[0062] like Figure 7As shown, the support platform 31 includes a high-temperature resistant glass support plate 32 and an image detection module located below the high-temperature resistant glass support plate 32; the image detection module takes in the lower surfaces of the hot pressing molding head 16 and the screen printing coloring head 17 that are moved above the high-temperature resistant glass support plate 32 to detect the position matching of the hot pressing molding head 16 and the screen printing coloring head 17.

[0063] The image detection module constitutes a vision alignment system. During initial equipment debugging or mold changeover in production, the system can sequentially drive the hot-pressing molding head 16 and the screen printing coloring head 17 to move above the detection area. A camera captures and records the precise image coordinates of unique feature points on the surface of each head through a glass plate. An image processing algorithm calculates the spatial transformation relationship between the feature coordinates of the two heads and feeds this deviation data back to the control system. Based on this, the control system fine-tunes and compensates for the lateral movement drive component of the screen printing head or the slide of the adaptive printing platform 4, thereby achieving absolute coordinate calibration and matching of the working areas of the two heads at the hardware level. This is more accurate and intelligent than simply relying on mechanical stroke positioning or through-beam sensors.

[0064] like Figures 1-3 As shown, the adaptive printing platform 4 has a roller 33 with a height lower than the high-temperature resistant glass support plate 32 on the side near the screen printing color-applying die 17, so that the fiber cloth is tilted. This not only forms a clearance zone to prevent the screen printing color-applying die 17 from accidentally contacting the surface of the fiber cloth, but also applies tension to the fiber cloth part of the adaptive printing platform 4, making it flatter.

[0065] This invention introduces a continuous tearable fiber fabric for embossing and coloring, as well as its preparation equipment. Specific examples are used to illustrate the principles and implementation methods of the invention. The descriptions of these embodiments are merely for the purpose of helping to understand the invention and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to the invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
