Description

Technical Field

[0001] This utility model relates to a three-dimensional embossed multilayer monofilament perforated jacquard fabric and shoe upper, belonging to the field of textile weaving. Background Technology

[0002] In the current field of shoe upper materials, as consumers' demands for wearing experience continue to rise, traditional shoe upper materials are gradually revealing many shortcomings. On the one hand, many conventional fabrics have poor breathability, and during prolonged wear, especially during exercise, they cannot expel moisture and heat from inside the shoe in time, leading to stuffy and sweaty feet, which in turn affects wearing comfort. On the other hand, the texture of the materials is relatively monotonous, lacking a delicate feel and elasticity, making it difficult to meet people's expectations for high-quality footwear products in terms of both visual and tactile aspects. Furthermore, the lack of three-dimensional shaping makes it difficult to create rich layers and dimensions, resulting in an overall shoe upper shape that is not full and vivid, limiting the diversity of shoe designs. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a three-dimensional concave-convex multilayer single-filament perforated jacquard fabric and shoe upper, so as to solve the technical problem that the existing fabrics cannot simultaneously achieve breathability, delicate texture and three-dimensionality.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a three-dimensional textured multilayer single-filament perforated jacquard fabric, comprising a surface layer, a middle layer, and a bottom layer, which includes:

[0013] The protrusion is formed by the middle layer multifilaments, together with the surface layer multifilaments and the bottom layer monofilaments or multifilaments, to form an air layer sandwich structure through the upper and lower loops;

[0014] The protrusion is formed by the middle layer monofilaments, which together with the surface layer monofilaments and the bottom layer monofilaments in an air layer sandwich structure through the upper and lower loops;

[0015] The protrusion is formed by the middle layer multifilaments forming an air layer sandwich structure together with the surface layer monofilaments and the bottom layer monofilaments through an upper and lower looping method.

[0016] The materials of the monofilament and multifilament are selected from at least one of the following: polyester fiber (polyester), polyamide fiber (nylon), polyurethane elastic fiber (spandex), polyurethane (PU), viscose fiber, animal fiber (including wool, silk), plant fiber (including cotton, linen, bamboo fiber); or high-shrinkage yarn, heat-melting yarn, and transparent yarn composed of modified forms of the above materials.

[0017] Furthermore, both the recessed portion and the flat portion are provided with through-hole structures, which include loop through-holes, flip-needle through-holes, and through-holes formed by the intermediate layer monofilaments.

[0018] Among them, the looped through holes are formed by the bottom multifilament through the looping operation, the turning through holes are formed by the top monofilament or multifilament through the turning through operation, and the through holes formed by the middle monofilament are formed by the middle monofilament being woven into the top and bottom layers or simultaneously with the looped through holes. The size and distribution of the through hole structure can be adjusted according to the jacquard and yarn density.

[0019] Furthermore, connecting portions are provided between the protrusions and recesses, and between the planar portion and the protrusions and recesses, to form edge transitions.

[0021] Furthermore, the protruding part and the flat part have a three-layer structure, which is composed of a surface layer yarn, a middle layer yarn and a bottom layer yarn, and the recessed part has a two-layer structure, which is composed of a surface layer yarn and a bottom layer yarn.

[0024] A preparation method comprising the following steps:

[0025] S1. Yarn preparation: Select the same or different yarns as the surface layer yarn, middle layer yarn and bottom layer yarn;

[0026] S2. Weaving and shaping: Through weaving process, a three-dimensional textured multi-layer monofilament perforated jacquard fabric with raised, recessed and flat surfaces is formed simultaneously.

[0027] The surface layer yarn is knitted with full needle to form a flat part, the middle layer yarn is knitted with upper and lower loops to form a raised part, and the bottom layer yarn is knitted with intermittent needles to pull down the surface layer to form a recessed part.

[0028] The beneficial effects of this utility model are:

[0029] The fabric in this application features a three-dimensional textured design, including raised sections, recessed sections, and a flat surface. The raised sections are formed by a sandwich structure of air layers created by the middle layer yarns using a loop-knitting method with the surface and bottom layers. This structure gives the upper a distinct three-dimensional sense of height, making its shape full and dynamic, breaking away from the flat limitations of traditional upper materials and providing more creative space for shoe design. Furthermore, the three-layer structure of the raised and flat surfaces, along with the double-layer structure of the recessed sections, combined with fine-needle knitting, further enriches the texture and layers of the upper, resulting in a delicate and elastic feel to the touch, enhancing the wearing experience and perceived quality.

[0030] In this application, the surface yarn is fully knitted to form a flat surface that fits snugly against the foot, ensuring the upper is not prone to loosening or deformation and providing a stable wearing effect. The recessed area is formed by the spandex-covered yarn in the bottom layer using a stitch-separated looping method to pull down the surface layer, making the upper more elastic, adapting to foot movement and deformation, reducing the feeling of restriction, and making wearing more free and comfortable. In addition, the connection between the raised and recessed areas, and between the flat area and the raised and recessed areas, achieves a natural transition through the stitch-separated looping process of the middle layer polyester multifilament and the stitch-separated looping process of the bottom spandex-covered yarn, avoiding friction and discomfort caused by abrupt changes in the upper structure, and reducing the occurrence of cracks at the connection points.

[0031] The fabric in this application has a perforated structure in the recessed and flat areas, including loop perforations, folded perforations, and perforations formed by the monofilaments in the middle layer. Through the above three breathable structures, the fabric has excellent breathability. The perforated structures work together to promote the circulation of air inside the shoe, which can efficiently expel moisture and heat, bringing a dry and comfortable shoe environment to the wearer and effectively reducing discomfort and odor caused by foot sweat.

[0040] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0041] like Figure 1 , Figure 2 As shown, this utility model provides a technical solution for a three-dimensional, textured, multi-layered monofilament perforated jacquard air-layer fabric: the fabric includes a surface layer, a middle layer, and a bottom layer, comprising:

[0042] The protrusion 1 is formed by the middle layer yarn through an upper and lower loop knitting method, together with the surface layer yarn and the bottom layer yarn to form an air layer sandwich structure.

[0043] The recessed portion 2 is formed by pulling down the surface layer of the bottom yarn using a needle-gathering method to create a recessed area.

[0044] The planar part 3 has a flat surface formed by the surface yarn using a full-needle knitting method.

[0045] In order to achieve the weaving of different protrusions, at least one of the intermediate layer yarn, the surface layer yarn and the bottom layer yarn of the protrusion 1 contains monofilament or multifilament. The intermediate layer yarn is woven by upper and lower loops and interwoven with the surface layer yarn and the bottom layer yarn to form an air layer sandwich structure.

[0046] The yarn combination forming the air-layer sandwich structure includes, but is not limited to:

[0047] The protrusion 1 is formed by the middle layer monofilament, which together with the surface layer multifilament and the bottom layer multifilament in an air layer sandwich structure through the upper and lower loops;

[0048] The protrusion 1 is formed by the middle layer monofilament, which together with the surface layer monofilament and the bottom layer multifilament in an air layer sandwich structure through the upper and lower loops;

[0049] The protrusion 1 is formed by the middle layer multifilaments through upper and lower loops, together with the surface layer monofilaments and the bottom layer multifilaments to form an air layer sandwich structure;

[0050] The protrusion 1 is formed by the middle layer multifilaments, together with the surface multifilaments and the bottom monofilaments or multifilaments, in an air layer sandwich structure through the upper and lower loops;

[0051] The protrusion 1 is formed by the middle layer monofilaments, which together with the surface layer monofilaments and the bottom layer monofilaments in an air layer sandwich structure through the upper and lower loops;

[0052] The protrusion 1 is formed by the middle layer multifilaments through upper and lower loops, together with the surface layer monofilaments and the bottom layer monofilaments to form an air layer sandwich structure.

[0053] To increase the applicability of the fabric, the monofilament and multifilament are made of at least one of the following materials: polyester fiber (polyester), polyamide fiber (nylon), polyurethane elastic fiber (spandex), polyurethane (PU), viscose fiber, animal fiber (including wool, silk), plant fiber (including cotton, linen, bamboo fiber); or high-shrinkage yarn, heat-melting yarn, or transparent yarn made of modified forms of the above materials.

[0054] To achieve different breathability performance, both the recessed part 2 and the flat part 3 are provided with a perforated structure, which includes a loop perforation, a turn-through perforation and a perforation formed by the monofilament of the intermediate layer.

[0055] Among them, the looped through holes are formed by the bottom multifilament through the looping operation, the turning through holes are formed by the top monofilament or multifilament through the turning through operation, and the through holes formed by the middle monofilament are formed by the middle monofilament being woven into the top and bottom layers or simultaneously with the looped through holes. The size and distribution of the through hole structure can be adjusted according to the jacquard and yarn density.

[0056] In order to achieve the transition between the parts, a connecting part 4 is provided between the protruding part 1 and the recessed part 2, and between the flat part 3 and the protruding part 1 and the recessed part 2 to form an edge transition.

[0057] To achieve a natural transition, the connecting part 4 uses the upper and lower looping process of the middle layer yarn and the spaced-needle looping process of the bottom layer yarn to achieve a seamless and natural transition between the protruding part 1 and the recessed part 2.

[0058] To form different structures, the protrusion 1 and the flat surface 3 are three-layer structures, consisting of surface yarn, middle yarn and bottom yarn, while the recess 2 is a two-layer structure, consisting of surface yarn and bottom yarn.

[0059] In order to form a surface structure with a three-dimensional and layered feel, the protrusion 1, the recess 2, and the flat surface 3 have a height difference with each other. The protrusion 1 protrudes upward relative to the flat surface 3, and the recess 2 is recessed downward relative to the flat surface 3.

[0060] like Figure 3 As shown, a shoe upper, at least a portion of which is composed of a three-dimensional textured multilayer monofilament perforated jacquard fabric, wherein... Figure 3 Only one example of the upper is provided, and the positions of the various parts of the upper can be adjusted and modified as needed.

[0061] A preparation method comprising the following steps:

[0062] S1. Yarn preparation: Select the same or different yarns as the surface layer yarn, middle layer yarn and bottom layer yarn;

[0063] S2, Weaving and forming: Through weaving process, a three-dimensional textured multi-layer monofilament perforated jacquard fabric with raised part 1, recessed part 2 and flat part 3 is formed simultaneously.

[0064] The surface layer yarn is knitted with full needle to form a flat part 3, the middle layer yarn is knitted with upper and lower loops to form a raised part 2, and the bottom layer yarn is knitted with intermittent needles to pull down the surface layer to form a recessed part 3.

[0065] In this application, the surface layer yarn is preferably transparent yarn or transparent multifilament yarn with a low F number; the middle layer yarn is preferably transparent yarn or polyester multifilament yarn; and the bottom layer yarn is preferably one of three types of yarn: spandex covered yarn, polyester multifilament yarn, and high shrinkage yarn. All bottom layer yarns are threaded through the needle cylinder with full needle coverage. When forming a recessed area, only the spandex covered yarn pulls down the surface layer through a needle-separated loop method to form a recess in that area. The polyester multifilament yarn and high shrinkage yarn in the bottom layer are only used for weaving the bottom layer and do not participate in the operation of forming the recessed area.

[0066] The following embodiments of this application use transparent yarn for the top layer, polyester multifilament yarn for the middle layer, polyester multifilament yarn for the bottom layer, spandex-covered yarn, and high-shrinkage yarn.

[0067] Example 1:

[0068] like Figure 4 As shown, the surface layer uses transparent yarn as the surface layer monofilament. In the protrusion 1, the surface layer monofilament is woven together with the polyester multifilament of the middle layer and the polyester multifilament, spandex covering yarn and high shrinkage yarn of the bottom layer through an up-and-down loop weaving method to form an air layer sandwich structure. The middle layer uses polyester multifilament. In the protrusion 1, the polyester multifilament of the middle layer is woven together with the transparent yarn of the surface layer and the polyester multifilament, spandex covering yarn and high shrinkage yarn of the bottom layer. The bottom layer uses polyester multifilament, spandex covering yarn and high shrinkage yarn. The three types of yarn are threaded through the needle cylinder with full needle, which makes the bottom layer structure stable and elastic.

[0069] Through the above-described weaving process, this application forms a raised portion 1 with a three-dimensional effect and a rich sense of layering. Compared with traditional single-layer woven fabrics, this application forms an air-layer sandwich structure, which can ensure the three-dimensional shape and structural stability of the raised portion 1. The tight interweaving of this multi-layer structure enhances the overall strength and durability of the fabric.

[0070] Example 2:

[0071] like Figure 5 As shown, in the recessed area 2, the transparent yarn on the surface layer is not woven, creating a recessed effect; the bottom polyester multifilament can be woven in a one-grid-one-stitch or full-needle knitting manner, while the spandex yarn is gathered on the needle plate with skipped stitches to form a loop, and the elasticity of the spandex is used to pull the surface layer down to form a recess; the polyester multifilament in the middle layer becomes the base yarn in the recessed area, and is woven together with the bottom polyester multifilament to enhance the structural stability of the bottom layer.

[0072] This application, through the aforementioned weaving process, forms a recessed portion 2 with good elasticity and conformability. The elastic tension of the spandex-covered yarn allows the recessed portion 2 to better conform to the body's curves, providing a comfortable wearing experience. Compared with traditional flat-woven fabrics, the recessed portion 2 design of this application not only increases the fabric's three-dimensionality and layering but also significantly improves its elasticity. This elasticity allows the shoe upper to better adapt to foot movement and deformation, reducing the feeling of restriction and improving wearing comfort. Simultaneously, the tight weaving of the underlying yarns enhances the fabric's structural stability, making the shoe upper less prone to deformation during wear and extending the product's lifespan.

[0073] Example 3:

[0074] like Figure 6 As shown, in the planar section 3 area, the transparent yarn A of the surface layer is woven with a full-needle knitting method to form a flat surface. The transparent yarn A of the surface layer is woven with every stitch on the needle plate to ensure the flatness and integrity of the planar section 3. The polyester multifilament C1 of the bottom layer is woven with a one-grid-one-base method. At the same time, where a hole is required, the adjacent bottom needle cylinder needles are woven with a full-needle knitting method. The needle plate starts with half a stitch and performs a tucking operation to pull the yarn woven by the needle cylinder to the needle plate to form a tucking, thereby forming a hole structure. The polyester multifilament B of the middle layer becomes a base in the planar section 3 area. Together with the polyester multifilament C1 of the bottom layer, the spandex covered yarn C2 and the high-shrinkage yarn C3, it enhances the structural stability of the planar section 3.

[0075] This application, through the aforementioned weaving method, can form a planar portion 3 with a perforated structure, enhancing the breathability of the fabric. Furthermore, the size of the perforated structure can be precisely controlled by adjusting the weaving process and the tightness of the yarn. Compared to traditional planar fabrics, the design and combination of various perforated structures in this application significantly improves the fabric's breathability.

[0076] Example 4:

[0077] The fabric in this application also uses a jacquard technique, which is a partial jacquard of two-tone monofilaments. It can be a two-tone jacquard that is transparent from top to bottom, or it can be a two-tone jacquard of only the surface monofilaments. In the case of two-tone jacquard, the transparent yarn A on the surface is jacquard woven on the needle plate in the area where the two-tone jacquard is required, while the polyester multifilament C1 on the bottom layer is woven in coordination on the needle cylinder, so that the jacquard pattern is clearly visible on both the front and back of the fabric. In the case of two-tone jacquard, the transparent yarn A on the surface monofilament is jacquard woven on the needle plate in the area where jacquard is required, while the polyester multifilament C1 on the bottom layer is woven with full needle, so that the jacquard pattern is only visible on the front of the fabric.

[0078] This design adds rich color variations and pattern decorations to the fabric, and the combination of jacquard patterns with the recessed part 2 and the flat part 3 can further enhance the three-dimensionality and layering of the fabric without affecting its breathability.

[0079] Example 5:

[0080] This application includes the following three types of through-hole structures: loop through-hole, needle-turn through-hole, and through-hole formed by intermediate layer monofilament:

[0081] Tuck-in perforations are created by pulling the yarn from the bottom multifilament to the other side of the top or bottom layer through a tuck-in operation (i.e., forming loops on the needle plate or cylinder), thus forming holes. The edges of these holes are relatively flat and the size is relatively uniform. Due to the greater depth of the holes, air can flow more smoothly between the two sides of the fabric, thereby enhancing the fabric's breathability.

[0082] Turn-over perforations are created by transferring loops from the surface monofilament or multifilament through a turn-over looping operation (i.e., transferring loops from the needle plate to the needle cylinder, or vice versa). These perforations have relatively smooth edges and are generally uniform in size. Because the perforations are mainly concentrated on the surface of the fabric, their depth is relatively shallow. Compared to tuck-in perforations, their breathability may be slightly weaker. However, by changing the number and frequency of the turn-over loops, diverse perforation patterns can be created.

[0083] The perforations formed by the middle layer monofilaments can be created by weaving small holes in the surface layer, small holes in the bottom layer, or by weaving the middle layer monofilaments simultaneously in both the surface and bottom layers, resulting in perforations that are open from top to bottom. These perforations increase the fabric's breathability and airflow, allowing air to circulate within the fabric through these small perforations, thus improving wearing comfort. Furthermore, these open-ended perforations can be combined with other perforation structures to create a composite perforation effect, further optimizing the fabric's breathability and wearing experience.

[0084] This application uses the combination of the above three perforation structures to form a perforation system for the fabric, which improves its breathability, three-dimensionality, aesthetics and wearing comfort, and meets the needs of use in different scenarios.

[0085] As can be seen from the embodiments, the three-dimensional textured multi-layer monofilament perforated jacquard air layer fabric of this application adopts a fine needle knitting method. Combined with its unique multi-layer structure design, it shows significant advantages in terms of production capacity and efficiency. Fine needle knitting can achieve a more refined knitting effect, making the perforated structure and three-dimensional layers of the fabric more precise and richer, bringing a more delicate and Q-feel. Through the different yarn combinations of the surface layer, middle layer and bottom layer, as well as the application of knitting techniques such as tucking and turning stitches, the knitting precision is improved while ensuring the high efficiency of the knitting process.

[0086] Compared with traditional weaving methods, the weaving process of this application can simultaneously weave the raised part 1, the recessed part 2, and the flat part 3 in one weaving cycle, reducing the complexity of the process and improving weaving efficiency. The tightness of the fine needle weaving also enhances the overall structural stability of the fabric, reduces the defect rate in the production process, and further increases production capacity. In addition, the yarn is used efficiently in the weaving process, reducing the waste of raw materials and lowering production costs. This efficient weaving method and optimized structural design make the fabric of this application more competitive in large-scale production, able to meet the market's large demand for high-quality, functional shoe upper materials, and provide strong support for enterprises to achieve efficient production and improved economic benefits.

[0087] Example 6:

[0088] This embodiment provides a method for preparing a three-dimensional textured multilayer monofilament perforated jacquard fabric, the specific steps of which are as follows:

[0089] S1. Yarn preparation: Select the same or different yarns as the surface layer yarn, middle layer yarn and bottom layer yarn;

[0090] S2, Weaving and forming: Through weaving process, a three-dimensional textured multi-layer monofilament perforated jacquard fabric with raised part 1, recessed part 2 and flat part 3 is formed simultaneously.

[0091] Flat section 3 weaving: Transparent silk is used as the surface yarn, and a flat flat section 3 is formed by full needle knitting. Full needle knitting can ensure that the flat section 3 has high density and stability, making the fabric surface smooth and flat, closely fitting the foot, and comfortable to wear.

[0092] Protrusion 1 weaving: Polyester multifilament is used as the middle layer yarn. The protrusion 1, together with the surface yarn and the bottom yarn, forms an air layer sandwich structure through the upper and lower loop weaving method. The upper and lower loop weaving makes the middle layer yarn form a loop between the surface yarn and the bottom yarn, thereby creating an air layer.

[0093] Recessed section 2 weaving: Using the spandex-covered yarn at the bottom layer, the nylon multifilament of the surface layer is pulled down in a looping manner to form a recessed area. The elasticity of the spandex-covered yarn gives recessed section 2 good elasticity and resilience, which can better fit the curve of the foot and provide a comfortable wearing experience, while increasing the three-dimensionality and layering of the fabric.

[0094] S3. Perforation and Connection Transition: A perforation structure is provided on the recessed part 2 and the flat part 3, and a seamless and natural transition is achieved between the raised part 1, the recessed part 2 and the flat part 3 through the connecting part 4. The design of the connecting part 4 avoids friction and discomfort caused by abrupt changes in the fabric structure, reduces the occurrence of cracks in the connection part, ensures the integrity and durability of the fabric, and makes the shoe upper more comfortable, fits better and is less prone to deformation during wear.

[0095] Through the above weaving method, this embodiment successfully prepared a multi-layered single-filament perforated jacquard fabric with a three-dimensional texture, good breathability and comfort. This fabric not only presents a rich sense of layering and three-dimensionality visually, which can meet people's aesthetic needs for high-quality footwear products, but also has excellent breathability, elasticity and fit.

[0096] The fabric in this application features a three-dimensional textured design, comprising a raised portion 1, a recessed portion 2, and a flat portion 3. The raised portion 1 is constructed by a sandwich structure formed by the middle layer yarns, the upper layer yarns, and the bottom layer yarns through a loop-knitting method. This unique structure gives the upper a distinct three-dimensional layered feel, making its shape full and dynamic, breaking away from the flat limitations of traditional upper materials and providing more creative space for shoe design. Simultaneously, the three-layer structure of the raised portion 1 and the flat portion 3, along with the double-layer structure of the recessed portion 2, combined with fine-needle knitting, further enriches the texture and layers of the upper, presenting a delicate and elastic feel to the touch, enhancing the wearing experience and sense of quality.

[0097] In this application, the surface yarn is fully knitted to form a flat surface 3, which can fit closely to the instep, ensuring that the shoe upper is not prone to loosening and deformation, and providing a stable wearing effect. The recessed part 2 is formed by the spandex-covered yarn in the bottom layer using a stitch-separated looping method to pull down the surface layer, making the shoe upper more elastic, adapting to the movement and deformation of the foot, reducing the feeling of restriction, and making the wearing more free and comfortable. In addition, the connection part 4 between the raised part 1 and the recessed part 2, and between the flat part 3 and the raised part 1 and the recessed part 2, achieves a natural transition through the upper and lower looping process of the middle layer polyester multifilament and the stitch-separated looping process of the bottom spandex-covered yarn, avoiding friction and discomfort caused by abrupt changes in the shoe upper, and reducing the occurrence of cracks in the connection part.

[0098] The fabric in this application has a perforated structure in the recessed part 2 and the flat part 3, which includes a loop perforation, a turn-knit perforation and a perforation formed by the monofilament of the middle layer. Through the above three breathable structures, the fabric has excellent breathability. The perforated structure works together to promote the circulation of air in the shoe, which can efficiently expel moisture and heat, and bring a dry and comfortable shoe environment to the wearer, which can effectively reduce the discomfort and odor caused by foot sweat.
