Description

Technical Field

[0001] This invention relates to the field of shoe upper material technology, and in particular to a jacquard open reed breathable fabric and its manufacturing method. Background Technology

[0002] With the popularization of global sports and health concepts and the deepening trend of consumption upgrading, modern footwear products have evolved from basic wearable items into carriers of ergonomic performance. According to the 2024 Global Footwear Technology Survey Report, 93.8% of consumers pay attention to the breathability of shoe uppers, surpassing appearance design (87.2%) to become the primary factor in purchasing decisions. This upgraded demand poses a serious challenge to traditional shoe upper materials—how to achieve efficient breathability management while maintaining structural integrity has become the core contradiction restricting the industry's development.

[0003] To address these issues, researchers considered ways to improve traditional woven fabrics, which suffer from structural air permeability barriers. This is because conventional woven uppers use a plain / twill weave, with a high density of warp and weft yarns interlacing to form a continuous, closed yarn network. While this structure provides excellent dimensional stability and tear resistance, it leads to the following drawbacks: blocked physical ventilation channels, with interlacing points occupying a large pore area, hindering airflow; low moisture diffusion efficiency, requiring water vapor to travel along the fiber surface in a circuitous manner, resulting in generally low moisture permeability; and a heat accumulation effect: in a 35°C environmental simulation experiment, the internal temperature of the woven upper was significantly higher than the ambient temperature threshold.

[0004] Replacing woven fabric with leno weave can partially solve the above problems. Leno weave forms a stable perforation structure through semi-permanent twisting of warp yarns. However, the twisted structure has certain mechanical defects, including: a reduction in the effective cross-sectional area of ​​the load-bearing yarns, leading to localized stress concentration; and structural instability, perforation deformation, and warp and weft yarn slippage after repeated bending, which leads to a decrease in its strength performance and makes it difficult to meet the abrasion resistance requirements of shoe uppers.

[0005] Finally, while existing jacquard techniques can enhance visual depth, they are subject to fundamental technical limitations. Conventional jacquard techniques create surface textures using long weft floats. While reducing the number of interlacing points can significantly improve fabric moisture permeability, it leads to decreased anti-slip properties, making it difficult to balance breathability and strength.

[0006] Therefore, it is of great significance to develop a new type of shoe upper material that can ensure the structural integrity and strength of the shoe upper while also having excellent breathability. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing shoe upper materials in terms of strength and breathability, and to provide a jacquard open reed breathable fabric and its manufacturing method. By using a special wearing method and combining weaving technology, an open reed area and a non-open reed area are connected in sequence to form a structure. The non-open reed area provides structural strength, while the open reed area performs the function of moisture wicking and breathability, so as to achieve the effect of shoe upper material with both strength and breathability.

[0008] The specific plan is as follows:

[0009] A jacquard open reed breathable fabric includes intersecting warp and weft yarns, with the spacing between adjacent warp yarns varying regularly to form a structure in which open reed areas and non-open reed areas are connected in sequence. In the structure, the open reed areas do not contain the warp yarns, and the non-open reed areas are formed by at least three warp yarns intersecting with the weft yarns.

[0010] Furthermore, the non-empty reed area is formed by the intersection of 3 parallel warp yarns and 1 to 5 weft yarns, and the spacing between the empty reed areas is one reed, the width of one reed being the width of the 3 parallel warp yarns.

[0011] Furthermore, the non-empty reed area is formed by the intersection of 3 to 16 parallel warp yarns and 1 to 10 weft yarns, and the spacing between the empty reed areas is two reeds, with the width of one reed being the width of 3 parallel warp yarns.

[0012] Furthermore, the non-empty reed area is formed by the intersection of 3 to 16 parallel warp yarns and 5 to 10 weft yarns, and the spacing between the empty reed areas is three reeds, with the width of one reed being the width of three parallel warp yarns.

[0013] Furthermore, the two sets of non-empty reed areas are brought closer together to form an effect of 3 to 16 parallel warp yarns and 1 to 10 weft yarns crossing each other. The spacing between the empty reed areas is four reeds, and the width of one reed is the width of three parallel warp yarns.

[0014] Furthermore, the jacquard open reed breathable fabric is partially formed with open reed areas and non-open reed areas connected in sequence.

[0015] Furthermore, the jacquard open reed breathable fabric has at least two different open reed zones.

[0016] Furthermore, the warp yarn is nylon multifilament or polyester multifilament, and the weft yarn is thermoplastic yarn.

[0017] Furthermore, the jacquard openwork breathable fabric has a single-layer structure.

[0018] Furthermore, the jacquard open reed breathable fabric includes a surface layer and a bottom layer, wherein the bottom layer is a plain weave, and the surface layer has a structure in which open reed areas and non-open reed areas are connected in sequence.

[0019] This invention also relates to a method for manufacturing a jacquard openwork reed breathable fabric, comprising the following steps:

[0020] S1. Design a fabric according to requirements. The fabric has a structure in which open reed areas and non-open reed areas are connected in sequence. The open reed areas do not contain warp yarns, and the non-open reed areas contain warp yarns and weft yarns.

[0021] S2, reed threading: After the warp yarns are pre-loaded into the woven warp head, the reed is threaded. Multiple warp yarns are threaded into each reed tooth, and then at least one reed tooth is left unthreaded. This process is repeated.

[0022] S3. Interweave the weft yarns with the warp yarns in sequence to obtain the initial woven product;

[0023] S4. The initial woven product is subjected to heating and pre-shrinking shaping treatment to obtain a jacquard open reed breathable fabric.

[0024] Furthermore, in the reed threading described in S2, three warp yarns are threaded through one reed tooth, and then one to two reed teeth are left unthreaded. The weft yarn consists of 1 to 5 yarns arranged side by side with the same weft direction. Using this method, a through-hole with a size of 0.05-0.5mm can be formed.

[0025] Furthermore, in the reed threading described in S2, 3 to 16 warp yarns are threaded through one reed tooth, and then 2 to 3 reed teeth are left unthreaded. The weft yarn consists of 1 to 10 yarns arranged side by side with the same weft direction. Using this method, a through-hole with a size of 0.3-1.5 mm can be formed.

[0026] Furthermore, in the reed threading described in S2, 3 to 16 warp yarns are threaded through one reed tooth, and then 3 to 4 reed teeth are left unthreaded. The weft yarn consists of 1 to 10 yarns arranged side by side with the same weft direction. Using this method, a through-hole with a size of 1-5 mm can be formed.

[0027] Furthermore, in the weaving described in S3, the non-empty reed areas are grouped in pairs. The warp yarns close to the empty reed area within the group change their structure with the weft yarns during weaving. The two adjacent warp yarns and weft yarns are in the same vertical position, that is, above and below the same weft yarn.

[0028] Furthermore, in the weaving process described in S3, a whole sheet of material is first woven by a machine, and then the surface layer and the bottom layer are separated in a localized area using warp yarns. The surface layer is combined with transparent monofilaments to implement skeining, so that the pattern of the bottom layer can be seen through the surface layer, making the pattern more layered.

[0029] Furthermore, the heating pre-shrinking and shaping process described in S4 is carried out at a temperature of 150–180°C at a speed of 10–15 m / min. Using this method, the size of the through-holes can be adjusted and fixed, for example, to achieve the effect of merging empty or non-empty reed areas locally.

[0030] The present invention also protects a shoe comprising the aforementioned jacquard reed breathable fabric.

[0031] Beneficial effects: The manufacturing method of the jacquard open reed breathable fabric provided by this invention forms perforations of different specifications through a special reed-threading method, which can significantly improve the breathability and wearing comfort of the shoe upper. At the same time, the fabric has good mechanical strength, meeting the requirements for abrasion resistance of shoe upper materials. Attached Figure Description

[0042] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Where specific techniques or conditions are not specified in the embodiments, they are performed in accordance with techniques or conditions described in the literature in the art or according to product instructions. Reagents or instruments whose manufacturers are not specified are all conventional products that can be obtained commercially.

[0043] Example 1

[0044] A jacquard open reed breathable fabric includes interlaced warp yarns 1 and weft yarns 2. The spacing between adjacent warp yarns 1 varies regularly, forming a structure in which open reed areas 3 and non-open reed areas 4 are sequentially connected. In this structure, the open reed areas 3 do not contain any warp yarns 1, and the non-open reed areas 4 are formed by at least three warp yarns 1 interlacing with the weft yarns 2. Using this structure, the open reed areas form breathable holes, the non-open reed areas provide sufficient fabric strength, and the interconnected open and non-open reed areas improve warp tear strength while maintaining the fabric's efficient moisture wicking capacity.

[0045] refer to Figure 1 This fabric is woven using a specific reed tooth arrangement. Three warp yarns are threaded through each reed tooth, then two reed teeth are left unthreaded, and this process is repeated to create a special weaving method of "three warp yarns per reed, two unthreaded reeds." This method results in a regular, spaced distribution of warp yarns on the fabric, laying the foundation for the subsequent formation of a breathable, open reed structure.

[0046] Specifically, the warp yarns are multifilament yarns, and the weft yarns are thermoplastic core-spun yarns. In a heated environment, the weft yarns melt and form bonding points, which play a role in bonding and fixing the fabric as a whole. Furthermore, by changing the structure of the warp and weft yarns, the adjacent warp and weft yarns in two groups are in the same vertical position, causing the non-hollow reed groups to lose their fixed position and come together. By changing the warp and weft interlacing structure and the misalignment of the weft yarns, different sizes of hole structures can be formed.

[0047] Example 2

[0048] Based on Example 1, this embodiment describes the specific structure of micropores formed on jacquard open reed breathable fabric. The micropore size can be 0.05-0.5mm.

[0049] refer to Figure 2 The fabric has a plain weave effect in some areas. The warp yarn 1 is made of nylon or polyester multifilament, and the weft yarn 2 is made of TPU core-spun yarn. During weaving, the specific reed threading method is: thread three reeds through one reed, leave one reed empty, and repeat this cycle. The empty reed area 3 forms micropores.

[0050] This embodiment is merely exemplary, and the present invention is not limited to this structure. Those skilled in the art should realize that the number of warp yarns inserted into each reed tooth can also be other values, such as 5, 6, 8, 10, 13 or 16 yarns. The different number of yarns will change the size of the empty reed area and the non-empty reed area, thereby forming a variety of fabric styles.

[0051] Example 3

[0052] A method for manufacturing a jacquard openwork breathable fabric includes the following steps:

[0053] S1. Design the fabric according to requirements. The fabric has a structure in which open reed areas and non-open reed areas are connected in sequence. The open reed areas do not contain warp yarns, and the non-open reed areas contain both warp and weft yarns. Specifically, when designing the shoe upper, a format file is created based on the relevant parameters of the shoe upper and input into the loom.

[0054] S2. Reed Threading: After the warp yarns are pre-loaded into the woven fabric, the reed is threaded using a 12.8 steel reed. The warp yarns are 420D high-strength nylon yarn. Three reeds are threaded per reed, with one reed left unthreaded. Figure 1 As shown; the weft yarn uses a single TPU core-spun yarn, which can play a role in bonding and fixing after heating, and this process is repeated.

[0055] S3. Interweave the weft yarns with the warp yarns in sequence. Specifically, first weave an initial product with a width of 180cm, using the following weaving method: Figure 3 As shown, the weaving process proceeds from bottom to top. Red indicates the start of the first shuttle weft yarn, and the machine automatically interweaves the weft yarn with the warp yarn in sequence. Black indicates the sinking of the weft yarn.

[0056] S4. The initial woven product is subjected to heat pre-shrinking and setting treatment at a temperature of 150-180℃ and a setting speed of 10-15m / min to obtain a jacquard open reed breathable fabric, the structure of which is as follows. Figure 3 The hollow reed area forms a microporous structure.

[0057] Example 4

[0058] Based on Example 1, this embodiment describes the specific structure of forming a central hole on a jacquard open reed breathable fabric. The size of the central hole can be 0.3-1.5mm.

[0059] refer to Figure 4 The fabric uses nylon or polyester multifilament for warp yarn 1 and TPU core-spun yarn for weft yarn 2. The weft yarn consists of two TPU core-spun yarns arranged side by side with the same weft direction. During partial weaving, a method of threading three yarns through one reed and leaving two reeds empty is adopted. Due to the expansion of the empty reeds, the empty reed area 3 forms a central hole.

[0060] This embodiment is merely exemplary, and the present invention is not limited to this structure. Those skilled in the art should realize that the number of yarns arranged side by side in the weft yarn can also be other values, such as 3, 5, 6, 8 or 10. The different number of weft yarns will change the size of the empty reed area and the non-empty reed area, thereby forming a variety of fabric styles.

Specifically, when designing the shoe upper, a format file is created based on the relevant parameters of the shoe upper and input into the loom.

[0064] S2, Reed threading: After the warp yarns are pre-loaded into the woven fabric, the reed is threaded using steel reeds with a reed size of 5.5-16. The warp yarns are 100D-900D high-strength nylon yarns. Three reeds are threaded through one reed, and two reeds are left empty. The weft yarns are two TPU core-spun yarns of the same structure arranged side by side. After heating, they can play a bonding role. This process is repeated.

[0065] S3. Interweave the weft yarns with the warp yarns in sequence. Specifically, first weave an initial product with a width of 180cm, using the following weaving method: Figure 3 As shown, the weaving process proceeds from bottom to top. Red indicates the start of the first shuttle weft yarn, and the machine automatically interweaves the weft yarn with the warp yarn in sequence. Black indicates the sinking of the weft yarn.

[0066] S4. The initial woven product is subjected to heat pre-shrinking and setting treatment at a temperature of 150-180℃ and a setting speed of 10-15m / min to obtain a jacquard open reed breathable fabric, the structure of which is as follows.

[0068] Based on Example 1, this embodiment describes the specific structure for forming large holes in jacquard reed breathable fabric, where the hole size can be 1-5mm.

[0069] refer to Figure 5 The fabric uses nylon or polyester multifilament for warp yarn 1 and TPU core-spun yarn for weft yarn 2. The weft yarn uses five TPU core-spun yarns arranged side by side with the same structure in the weft direction. In the partial weaving, three yarns are threaded through one reed, leaving three reeds empty. Due to the further expansion of the empty reeds, the empty reed area 3 forms a large hole.

[0070] Example 7

[0071] A method for manufacturing a jacquard openwork breathable fabric includes the following steps:

[0072] S1. Design the fabric according to requirements. The fabric has a structure in which open reed areas and non-open reed areas are connected in sequence. The open reed areas do not contain warp yarns, and the non-open reed areas contain both warp and weft yarns. Specifically, when designing the shoe upper, a format file is created based on the relevant parameters of the shoe upper and input into the loom.

[0073] S2, Reed threading: After the warp yarns are pre-loaded into the woven fabric, the reed is threaded using steel reeds with a reed size of 5.5-16. The warp yarns are 100D-900D high-strength nylon yarns, with three reeds threaded through each reed and three reeds left empty. The weft yarns are 5 TPU core-spun yarns, which can act as adhesives after heating. This process is repeated.

[0074] S3. Interweave the weft yarns with the warp yarns in sequence. Specifically, first weave an initial product with a width of 180CM. Weave from bottom to top. Red indicates the start of the first shuttle weft yarn. The machine automatically interweaves the weft yarns with the warp yarns in sequence. Black indicates the weft yarn sinking.

[0076] Example 8

[0077] Based on Example 1, this embodiment describes the specific structure for forming large holes in jacquard reed breathable fabric, where the hole size can be 1-5mm.

[0078] refer to Figure 6 The fabric uses nylon or polyester multifilament for warp yarn 1 and TPU core-spun yarn for weft yarn 2. The weft yarn consists of five TPU core-spun yarns arranged side by side with the same weft structure. During partial weaving, a method of threading three yarns through one reed and leaving two reeds empty is adopted. The non-empty reed areas with medium or micro holes are grouped together in pairs. During weaving, the warp yarns close to the empty reed area 3 in the group change the structure of the warp and weft yarns. The two adjacent warp and weft yarns are in the same vertical position, above and below the same weft yarn. Because the structures between them are the same, the non-empty reed groups lose their fixedness and merge together. At the same time, the weft yarns of the adjacent empty reed area 3 remain misaligned with the warp yarns, and the empty reed area 3 forms a large hole.

[0079] Example 9

[0080] A method for manufacturing a jacquard openwork breathable fabric includes the following steps:

[0081] S1. Design the fabric according to requirements. The fabric has a structure in which open reed areas and non-open reed areas are connected in sequence. The open reed areas do not contain warp yarns, and the non-open reed areas contain both warp and weft yarns. Specifically, when designing the shoe upper, a format file is created based on the relevant parameters of the shoe upper and input into the loom.

[0082] S2, Reed threading: After the yarn is pre-loaded into the warp head of the woven fabric, the reed is threaded. A steel reed with a reed size of 5.5-16 is used. The warp yarn is 100D-900D nylon high-strength yarn. Three reeds are threaded into one reed, and two reeds are left empty. The weft yarn uses 5 TPU core-spun yarns, which can play a bonding role after heating.

[0083] S3. Interweave the weft yarns with the warp yarns in sequence. Specifically, first weave an initial product with a width of 180CM. Weave from bottom to top. Red indicates the start of the first shuttle weft yarn. The machine automatically interweaves the weft yarns with the warp yarns in sequence. Black indicates the weft yarn sinking.

[0084] S4. The initial woven product is subjected to heat pre-shrinking and setting treatment at 150℃ and at a speed of 10-15m / min to obtain a jacquard open reed breathable fabric, the structure of which is as follows. Figure 6 .

[0085] This embodiment utilizes structural changes on both sides of the empty reed area, combined with weft structural changes, to form large holes. If the structures on both sides of the empty area are identical, they will merge towards the empty region; if the structures are different, such as misalignment, they will not merge towards the empty region, and a through hole will form in the empty foil area. In a localized section of the fabric, non-empty reed areas are grouped in pairs. During weaving, the warp yarns near the empty reed area in each group change their vertical position relative to the weft yarns. The two adjacent warp and weft yarns are in the same vertical position, located above and below the same weft yarn. Because the structures are identical, the non-empty reed groups lose their fixed merging, while the weft yarns in adjacent empty reed areas maintain their misalignment with the warp yarns, forming large holes in the empty reed area. (See the actual image for reference.) Figure 7 , Figure 8 and Figure 9 .

[0086] Example 10

[0087] This embodiment, based on Embodiment 1, introduces a jacquard open reed breathable fabric with at least two different open reed zones, employing an alternating pattern of micropores and medium-sized holes.

Specifically, the surface layer has micropores, the warp yarns are made of nylon or polyester multifilament, and the weft yarns are made of TPU core-spun yarn. During weaving, three yarns are threaded through one reed, leaving one reed empty, and the open reed areas form micropores.

[0091] In a preferred embodiment, the fabric utilizes warp yarn layering in certain areas, and the surface layer incorporates transparent monofilaments with tangles based on the above structure, allowing the underlying pattern to be seen through the surface layer, thus creating a layered pattern.

[0092] This embodiment is merely exemplary, and the present invention is not limited to this structure. Those skilled in the art should realize that there are other implementation methods besides plain weave, such as jacquard weave, twill weave, and combinations of these weaves, thereby forming a variety of layered fabric styles.
