Description

Technical Field

[0001] This utility model relates to the field of textile fabrics, and in particular to a three-dimensional filling fabric. Background Technology

[0002] In recent years, with the increasing demand for personalization and comfort among young consumers, 3D filled fabrics have gradually become a research hotspot in the textile industry due to their unique visual and tactile experience. Compared with traditional flat fabrics, 3D fabrics, through the three-dimensional structure formed by differences in fiber shrinkage, can create a rich sense of layering and a fluffy texture, showing broad application potential in clothing, home furnishings, and other fields.

[0003] The three-dimensional effect is mainly achieved through the difference in shrinkage between elastic fibers (such as spandex) and non-elastic fibers (such as cotton and polyester) on a single plane. During the weaving process, these two types of fibers have different heat shrinkage rates, resulting in uneven shrinkage after being heated, thus creating a textured or three-dimensional filling effect.

[0004] To achieve a significant three-dimensional effect, the fiber density or number of layers needs to be increased, which leads to an increase in fabric weight and affects comfort; moreover, the high-density fiber structure hinders air circulation, which can easily cause stuffiness, especially in summer or sports scenarios. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a three-dimensional filling fabric that can achieve a three-dimensional effect while ensuring lightweight and breathability.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A three-dimensional filled fabric includes a top layer, a middle layer, and a bottom layer; The intermediate layer includes alternating first and second braided areas, and the thickness of the second braided area is less than the thickness of the first braided area; The first weaving area adopts a three-dimensional support structure.

[0007] Furthermore, the first weaving area includes: At least one of the following: a monofilament filling area woven with monofilament, a multifilament filling area woven with multifilament, and a composite filling area woven with a mixture of monofilament and multifilament.

[0008] Furthermore, the thickness of the composite filling region or the multifilament filling region is greater than the thickness of the monofilament filling region.

[0009] Furthermore, the second weaving area includes a cutout area.

[0010] Furthermore, the monofilament filling area is a monofilament jacquard weaving area.

[0011] Furthermore, the filling ratio of monofilaments in the monofilament filling area is 20-100%.

[0012] Furthermore, the multifilament filling area is a multifilament jacquard weaving area.

[0013] Furthermore, the filling ratio of multifilaments in the multifilament filling area is 20-100%.

[0014] Furthermore, the composite filling area is formed by mixing and weaving the monofilament filling area and the multifilament filling area.

[0015] Furthermore, the top and bottom layers adopt a breathable structure.

[0016] The beneficial effects of this utility model are as follows: This utility model relates to a three-dimensional filling fabric, which constructs a three-layer structure of "surface layer + middle layer + bottom layer". The middle layer adopts an alternating arrangement of a first weaving area and a second weaving area. The second weaving area is thinner, which can reduce the amount of fiber used in this area. Compared with the existing technology of full-area high-density filling, it significantly reduces the total amount of fiber in the fabric and solves the problem of high weight. At the same time, the second weaving area has natural gaps due to the fewer fibers, which, when distributed alternately with the first weaving area, form a continuous air channel, enhance air flow, and improve breathability. Moreover, the first weaving area is thicker than the second weaving area. The difference in thickness between the two creates a concave-convex contrast. Combined with the three-dimensional support structure, the three-dimensional effect can be guaranteed without increasing the density or number of layers, achieving a synergy of "lightweight, highly breathable, and strong three-dimensionality".

[0018] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Definitions: Three-dimensional support structure: A three-dimensional support structure refers to the use of yarn material selection and weaving process design to create a three-dimensional structure in the middle layer of the fabric with a certain thickness, strength and shape stability, thereby achieving a combination of support and three-dimensional effect.

[0020] Monofilament: refers to yarn composed of a single continuous fiber, which has high rigidity, stiffness and transparency.

[0021] Multifilament: refers to yarn made of multiple continuous fibers (usually dozens to hundreds) twisted or combined. It has a finer diameter and is soft, fluffy, and elastic. Through the synergistic effect of multiple fibers, it combines a certain strength with flexibility, has a delicate feel, and is not easily broken.

[0022] Monofilament and multifilament blending: This involves combining monofilaments and multifilaments in the same filling area to create a composite structure that combines the advantages of both. During double-needle bed knitting using Jacquard combs, monofilaments and multifilaments are interwoven, stacked, or nested according to a designed ratio or spatial distribution. For example, monofilaments form a basic support skeleton using loops or weft insertion, while multifilaments fill the gaps in the skeleton and cover the surface of the monofilaments, forming a composite structure of "rigid skeleton + flexible filling"; or both can alternately participate in loop formation at different knitting stages, allowing the stiffness of the monofilaments and the bulkiness of the multifilaments to be uniformly integrated at the microscopic level.

[0023] Please refer to Figures 1 to 5 A type of filled three-dimensional fabric, comprising a top layer 1, a middle layer 2, and a bottom layer 3; The intermediate layer includes alternating first and second braided areas, and the thickness of the second braided area is less than the thickness of the first braided area; The first weaving area adopts a three-dimensional support structure.

[0024] As can be seen from the above description, the beneficial effects of this utility model are as follows: It constructs a three-layer structure of "surface layer + middle layer + bottom layer". The middle layer 2 uses alternating first weaving area 21 and second weaving area 22. The second weaving area 22 is thinner, which reduces the amount of fiber used in this area. Compared with the existing technology of high-density filling throughout the entire area, it significantly reduces the total fiber content of the fabric and solves the problem of high weight. At the same time, the second weaving area 22, due to its fewer fibers, forms natural gaps, which, when alternately distributed with the first weaving area 21, create a continuous air channel, enhancing airflow and improving breathability. Furthermore, the first weaving area 21 is thicker than the second weaving area 22, and the difference in thickness creates a concave-convex contrast. Combined with the three-dimensional support structure, a three-dimensional effect can be guaranteed without increasing density or number of layers, achieving a synergistic effect of "lightweight, highly breathable, and strong three-dimensionality".

[0025] Furthermore, the first weaving area 21 includes: At least one of the following: monofilament filling area 211 woven with monofilament, multifilament filling area 212 woven with multifilament, and composite filling area 213 woven with a mixture of monofilament and multifilament.

[0026] As described above, the first weaving area 21 explicitly includes at least one of a monofilament filling area 211, a multifilament filling area 212, and a composite filling area 213, thus refining the selection range of filling methods. The monofilament filling area 211 provides strong support; the multifilament filling area 212 is soft and fluffy; and the composite filling area 213 combines the advantages of both, with the multifilament physically enveloping the monofilament, utilizing the fluffy structure of the multifilament to provide cushioning space for the monofilament and reduce the risk of direct compression. It can be flexibly combined according to different application scenarios (such as the need for crispness in clothing or the need for softness in home furnishings), improving the applicability and functional targeting of the fabric.

[0027] Furthermore, the thickness of the composite filling region 213 or the multifilament filling region 212 is greater than the thickness of the monofilament filling region 211.

[0028] As described above, the thicker composite filling area 213 and multifilament filling area 212 provide a fuller, more three-dimensional shape and a soft, fluffy feel, while the thinner monofilament filling area 211 ensures rigid support while reducing material usage. This difference in thickness creates rich visual layers, enhancing the fabric's three-dimensional expression. The increased thickness of the multifilament filling area 212 improves its wrapping properties, preventing monofilaments from being exposed under stress and optimizing the feel. The increased thickness of the composite filling area 213 strengthens the synergistic effect of "support + softness," adapting to scenarios requiring high fullness. Simultaneously, the differentiated thickness design allows for the allocation of materials as needed, controlling the overall weight while maintaining a three-dimensional effect, balancing functionality and lightweight requirements, and expanding the fabric's adaptability in clothing, home furnishings, and other scenarios.

[0029] Furthermore, the second weaving area 22 includes a hollowed-out area.

[0030] As described above, the second weave zone 22 includes a perforated area, further reducing the amount of fiber used in this area and significantly reducing the fabric weight. The perforated structure directly forms breathable holes, which, in conjunction with the gaps in the first weave zone 21 alternating with the middle layer 2 and the structure of the top layer 1 and bottom layer 3, create a more efficient air circulation channel, greatly improving breathability, especially suitable for summer or sports scenarios, reducing stuffiness. Specifically: From a lateral perspective, although the first weaving area (filling area) of the intermediate layer is filled with monofilaments / multifilaments, there are natural gaps between the three-dimensional support structures formed by the double needle bed weaving (such as the gaps between monofilament skeletons and the micropores of the fluffy multifilament structure); while the hollow structure of the second weaving area directly forms through holes. These holes are connected to the gaps in the first weaving area, linking the scattered filling area gaps into a lateral circulation network, allowing air to diffuse freely inside the intermediate layer and avoiding circulation interruption due to local blockage.

[0031] From a longitudinal perspective, the top and bottom layers themselves have breathable structures (such as the mesh jacquard of the top layer and the plain / regular mesh of the bottom layer), providing "entry" and "exit" for air to enter and exit: outside air can enter the fabric through the mesh or gaps of the top layer, flow through the middle layer, and then be discharged through the breathable structure of the bottom layer (or enter from the bottom layer and be discharged from the top layer in the opposite direction), forming a longitudinal channel that runs through the thickness of the fabric.

[0032] Overall, the three layers form a complete circulation path: "top layer inlet → middle layer lateral connection (filling gaps + perforations) → bottom layer outlet." The breathable structure of the top and bottom layers ensures efficient airflow into and out of the fabric, the filling gaps in the middle layer provide the "main channels" for vertical circulation, and the perforated structure acts as a "lateral hub" connecting the main channels, eliminating dead zones. This synergy allows for increased airflow compared to a single structure.

[0033] Furthermore, the monofilament filling area 211 is a monofilament jacquard weaving area.

[0034] As described above, the monofilament filling area 211 is woven from monofilaments using a jacquard technique. The jacquard process can precisely control the distribution density and shape of the monofilaments, ensuring uniform support. At the same time, it avoids the monofilaments from being exposed on the fabric surface due to their messy distribution, thus improving the fabric's smoothness and neatness and solving the problem of poor tactile feel caused by exposed monofilaments.

[0035] Furthermore, the filling ratio of monofilaments in the monofilament filling area 211 is 20-100%.

[0036] As described above, the adjustable range of monofilament filling ratio from 20% to 100% allows for flexible adjustment based on the desired 3D effect: a lower ratio (e.g., 20%) reduces monofilament usage, achieving lightweighting; a higher ratio (e.g., 100%) enhances support and ensures stiffness. This adapts to different application scenarios (e.g., lightweight clothing, thick home furnishings), improving the flexibility and practicality of the solution.

[0037] Furthermore, the multifilament filling area 212 is a multifilament jacquard weaving area.

[0038] As described above, the multifilament filling area 212 is made of multifilament woven in a jacquard manner. The jacquard process can precisely control the interlacing density and distribution of multifilaments, making the multifilament filling more uniform and enhancing the softness and fluffiness of the fabric. At the same time, it avoids the heaviness caused by the accumulation of multifilaments, improves the tactile comfort, and takes into account both the three-dimensional effect and skin-friendliness.

[0039] Furthermore, the filling ratio of multifilaments in the multifilament filling area 212 is 20-100%.

[0040] As described above, the adjustable range of multifilament filling ratio from 20% to 100% adapts to different softness and fullness requirements: a low ratio (e.g., 20%) reduces the amount of multifilament used and lowers the weight; a high ratio (e.g., 100%) enhances the fullness of the filling and improves the fabric's fluffiness. This flexibly matches the tactile requirements of different scenarios such as clothing and home textiles, expanding the range of applications.

[0041] Furthermore, the composite filling area 213 is formed by mixing and weaving the monofilament filling area 211 and the multifilament filling area 212.

[0042] As described above, the composite filling area 213 is formed by stacking the monofilament filling area 211 and the multifilament filling area 212. The monofilament provides rigid support, while the multifilament provides flexible filling. The stacking of the two achieves a synergy of "support + softness". At the same time, the stacked structure wraps the monofilament with multifilament to prevent the monofilament from being exposed, improves the feel, and enhances the fullness and structural stability of the three-dimensional filling.

[0043] Furthermore, the top layer 1 and the bottom layer 3 adopt a breathable structure.

[0044] As described above, the surface layer 1 and the bottom layer 3 adopt a breathable structure, which, together with the alternating filling / second weaving area 22 of the middle layer 2, forms a through-breathing system of "surface breathable channel + middle layer 2 gap", which accelerates air circulation and solves the stuffiness problem caused by the high-density structure of the existing technology; at the same time, the breathable structure does not affect the overall shape stability of the fabric, and takes into account both breathability and structural strength.

[0045] This utility model discloses a three-dimensional filling fabric, which is suitable for scenarios where textile fabrics have requirements for three-dimensional visual / tactile feel, lightweight and breathability, and is especially suitable for fabric production in the fields of clothing and home furnishing.

[0046] Please refer to Figures 1 to 5 Embodiment 1 of this utility model is as follows: For reference Figure 1 A type of filled three-dimensional fabric, comprising a top layer 1, a middle layer 2, and a bottom layer 3; The top layer 1 and the bottom layer 3 adopt a breathable structure; In this embodiment, the top layer 1 and the bottom layer 3 adopt a plain weave, regular mesh, or jacquard structure, woven with jacquard combs and / or ground combs. There are two jacquard methods: one is jacquard weaving patterns using jacquard combs, and the other is jacquard weaving mesh patterns using both jacquard combs and ground combs. The plain weave / regular mesh is woven with ground combs.

[0047] For reference Figure 2 The intermediate layer 2 includes alternating first braided areas 21 and second braided areas 22. The thickness of the second braided area 22 is less than the thickness of the first braided area 21. For reference Figures 3 to 5 The first weaving area 21 adopts a three-dimensional support structure. In this embodiment, it includes the following three types, all of which serve the goal of "forming a stable three-dimensional shape through yarn combination and structural design": (1) It is formed by using monofilaments in Jacquard combs through looping, weft insertion, or reciprocating looping knitting on a double needle bed. Monofilaments themselves have high rigidity, and double needle bed knitting makes them form regular columnar or grid-like supports in the middle layer of the fabric. The stiffness of the monofilaments resists external pressure and ensures the durability of the three-dimensional shape.

[0048] (2) It is formed by using multifilaments (such as stretch textured yarn) in Jacquard combs and weaving them into loops in sequence through a double needle bed. Multifilaments are composed of multiple fibers, which have fluffiness and flexibility. After weaving, they form a porous structure similar to a "honeycomb". The elastic deformation between the fibers buffers the pressure while maintaining the overall fluffi and three-dimensional effect.

[0049] (3) It is formed by stacking and weaving monofilament filling area and multifilament filling area, which has the advantages of both rigidity and flexibility. Monofilament provides basic skeleton support to ensure three-dimensional stiffness; multifilament fills the gap between monofilament, uses its fluffiness to buffer external force, and at the same time wraps the monofilament to avoid exposure, thus achieving a balance of "stiff but not rigid, soft and supportive".

[0050] That is, it includes at least one of the following: monofilament filling area 211 woven with monofilament, multifilament filling area 212 woven with multifilament, and composite filling area 213 woven with a mixture of monofilament and multifilament.

[0051] In this embodiment, the thickness of the composite filling region 213 or the multifilament filling region 212 is greater than the thickness of the monofilament filling region 211.

[0052] The monofilament filling area 211 is a monofilament jacquard weaving area, and the filling ratio of monofilament is 20-100%.

[0053] In this embodiment, the weaving of the monofilament filling area 211 is carried out in one of the following two ways: (1) Jacquard comb A uses monofilament coiled warp feeding, and makes loops and weft weft alternately woven on needle bed A and needle bed B to form monofilament filling area 211, which has a certain height and thickness, and has good buffering and support performance; this structure is compared with the reciprocating weaving between needle bed A and needle bed B, which greatly reduces yarn tension and the monofilament loops are uniform and flat, and will not be squeezed and deformed.

[0054] Correspondingly, the weaving of the second weaving area 22 includes: Jacquard comb A does not form loops on needle bed A, but only performs long-cross needle structure (which can be heavy warp weft weft structure, heavy warp loop structure or multi-needle warp plain structure with more than 3 needles) on needle bed B. The tension of this structure is close to the weaving tension of Jacquard comb A in the first weaving area 21, thereby balancing the tension of the head and forming part of the bottom / top layer of the second weaving area 22, and the middle of the second weaving area is hollowed out.

[0055] (2) Jacquard comb A uses a monofilament yarn frame for warping, and performs reciprocating loop knitting on needle bed A and needle bed B to form a monofilament filling area 211, which has a certain height and thickness.

[0056] Correspondingly, the weaving of the second weaving area 22 includes: Jacquard comb A does not form loops on needle bed A, but only forms loops on needle bed B. This tension structure is significantly different from the weaving tension of Jacquard comb A in the first weaving zone 21. The tension is adjusted by the yarn frame feeding method to form part of the bottom / top layer of the second weaving zone 22, and the middle of the second weaving zone is hollowed out.

[0057] For reference Figure 3 When using monofilament weaving ( Figure 3 The red threads in the diagram represent monofilament weaving. During the first weaving zone 21, different methods are used to weave the second weaving zone 22 based on different warp feeding methods, forming part of the bottom / top layer of the second weaving zone 22 (e.g., ...). Figure 3 The red section at the bottom of the second weave zone 22 balances the tension. Meanwhile, the middle of the second weave zone 22 features a hollow design, significantly increasing the fabric's breathability and lightness.

[0058] The multifilament filling area 212 is a multifilament jacquard weaving area, and the multifilament filling ratio is 20-100%.

[0059] In this embodiment, the Jacquard comb B can also be made of multifilament yarn, which is then woven in loops on the needle bed A and needle bed B to form a multifilament filling area 212.

[0060] Correspondingly, the Jacquard comb B forms loops on the needle bed A but not on the needle bed B, forming part of the second knitting zone 22 surface layer 1. This structure has a large tension difference with the Jacquard comb B in the multifilament filling zone 212. The tension is balanced by using the yarn frame to feed the warp, and the hollow center greatly reduces the weight of the fabric.

[0061] For reference Figure 4 When using monofilament weaving ( Figure 4 The blue threads in the diagram represent multifilament weaving. When weaving the first weaving area 21, the second weaving area 22 is woven using the method described above, forming part of the bottom / top layer of the second weaving area 22 (e.g., Figure 3 The blue section at the top of the second weave zone 22 balances the tension. Meanwhile, the middle of the second weave zone 22 features a hollow design, significantly increasing the fabric's breathability and lightness.

[0062] For reference Figure 5 The composite filling area 213 is formed by mixing and weaving the monofilament filling area 211 and the multifilament filling area 212.

[0063] That is, the second knitting zone 22 adopts single-needle bed directional knitting, that is, the Jacquard comb is only formed in a single loop on the first or second needle bed, and its thickness is much smaller than that of the first knitting zone.

[0064] Specifically, please refer to Figure 3 The second weaving area 22, based on the weaving method of the first weaving area 21, selects an appropriate weaving method to form part of the bottom / top layer of the second weaving area 22 (which can be understood as having a certain degree of overlap with the bottom layer 3 / top layer 1), that is... Figure 3 , Figure 4 , Figure 5 In the middle, the top of the openwork area 22 is woven with red / blue fabric, which can balance the tension. Meanwhile, the second weave area 22 in the middle, that is, between the overlapping weave of the surface layer 1 and the bottom layer 3, adopts an openwork design, which significantly increases the lightness and breathability of the fabric.

[0065] In summary, the three-dimensional filled fabric provided by this utility model achieves multiple beneficial effects through the synergy of multi-layer structural design and differentiated filling: the middle layer 2 alternately sets filling and the second weaving area 22, and the first weaving area 21 is thicker. Combined with the flexible selection of monofilament, multifilament, and composite filling, a significant three-dimensional effect can be formed without increasing fiber density or number of layers, solving the problem of excessive weight caused by the thickening of traditional three-dimensional fabrics; the second weaving area 22 contains a hollow area, which, together with the breathable structure of the surface layer 1 and the bottom layer 3, constructs a through air circulation channel, greatly improving breathability and alleviating the stuffiness in summer or sports scenarios; the monofilament filling area 211 enhances support through jacquard weaving, the multifilament filling area 212 improves softness, and the composite filling area 213 combines the advantages of both, and the wrapping of monofilament by multifilament can prevent monofilament from being exposed, optimizing the hand feel; the adjustable range of filling ratio and diversified filling methods can adapt to the functional needs of different scenarios such as clothing and home furnishing, achieving a comprehensive performance improvement of "lightweight, highly breathable, three-dimensional controllable, and delicate hand feel", significantly expanding the application value of the fabric.

[0066] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
