Description

Technical Field

[0001] The invention relates to the technical field of woven shoe uppers, in particular to a processing technology of a breathable partially sheared woven shoe upper. Background Art

[0002] Traditional vamps are generally composed of several parts connected to each other, and the connection method is mainly manual sewing or sewing by a needle machine. Such a production method is time-consuming and labor-intensive, and due to the differences in the workers' manual craftsmanship, it is impossible to ensure the aesthetics of the joints of the vamps or even the entire vamp. The Chinese patent with the authorization announcement number CN106637582B discloses a processing technology for a breathable partially sheared woven vamp. The outer layer of the vamp is made of spandex-coated yarn and twisted yarn / high-elastic yarn mixed and interwoven to form a pattern. The yarn texture is evenly distributed to balance the force. The inner layer of the vamp is woven with high-elastic yarn as the lining, which makes the lining soft, so that the vamp has the advantages of good elasticity and comfortable wearing.

[0003] In the prior art, there is no report of a woven upper with a shearing structure. Adding a shearing structure to the upper can increase the three-dimensional sense of the upper, but those skilled in the art may consider that adding a shearing structure will affect the comfort and breathability of the upper. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a processing technology for a breathable partially sheared woven shoe upper, so that the produced shoe upper has a partial sheared structure and has three-dimensional sense, comfort and breathability.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] The processing technology of the breathable partially sheared woven shoe upper comprises the following steps:

[0007] Step 1: Select the yarn and load it on the shuttle loom;

[0008] Yarn includes:

[0009] The first weft yarn is 200-400D polyester high elastic yarn;

[0010] The second weft yarn is 800-1000D polyester high elastic yarn;

[0011] The warp yarn is 130-170D nylon fish silk;

[0012] Step 2: Design the upper, and input the upper design pattern into the shuttle loom, which weaves the upper according to the designed parameters to obtain the initial product of the woven upper.

[0013] The upper includes sheared woven areas and non-sheared areas;

[0014] The shear weaving area is a first weft yarn and a second weft yarn interlaced with the warp yarn respectively;

[0015] The non-shearing area is where only the first weft yarn is interwoven with the warp yarn, and the second weft yarn floats on the surface;

[0016] Step 3: Use a shearing device to cut off the second weft yarn at the edge of the sheared weaving area, so that the end of the second weft yarn that does not participate in the interweaving retains a length of 2-4 mm, and the fibers of the yarn at the end of the second weft yarn are loose to form a sheared portion;

[0017] Step 4: The upper is shaped by a hot pressing and shaping device to obtain a breathable partially sheared woven upper.

[0018] Furthermore, in the processing technology of the above-mentioned breathable partially sheared woven upper, the first weft yarn is 300D polyester high-elastic yarn.

[0019] Furthermore, in the processing technology of the above-mentioned breathable partially sheared woven upper, the second weft yarn is 900D polyester high-elastic yarn.

[0020] Furthermore, in the processing technology of the above-mentioned breathable partially sheared woven upper, the warp yarn is 150D nylon fish silk.

[0021] Furthermore, in the processing technology of the above-mentioned breathable partially sheared woven upper, in the sheared woven area, the interweaving density of the first weft yarn is greater than the interweaving density of the second weft yarn.

[0022] Furthermore, in the processing technology of the above-mentioned breathable partially sheared woven shoe upper, two warp yarns that are interlaced and close to each other are provided at the edge of the sheared woven area.

[0023] Furthermore, in the processing technology of the above-mentioned breathable partially sheared woven upper, in step 2, the shuttle loom adopts an electronic rapier jacquard shuttle loom.

[0024] Furthermore, in the processing technology of the above-mentioned breathable partially sheared woven upper, in step 3, the end portion not involved in the interweaving retains a length of 3 mm.

[0025] The invention also protects a breathable type partially sheared woven shoe upper obtained by a processing technology of the breathable type partially sheared woven shoe upper.

[0026] The beneficial effects of the present invention are as follows: in the present invention, the warp yarn is made of nylon fish silk and the weft yarn is made of polyester high-elastic yarn, so that the upper has the advantages of elasticity, breathability and comfort, wherein the first weft yarn is interwoven with the warp yarn throughout the entire process, while the second weft yarn is interwoven with the warp yarn only in the shearing and weaving area, and other non-shearing areas do not participate in the weaving, floating on the surface of the first weft yarn and the warp yarn. After the initial product of the upper is woven, the second weft yarn at the edge of the shearing and weaving area is cut by a shearing device, so that the end of the second weft yarn that does not participate in the interweaving retains a length of 2-4mm, so that the fibers of the yarn at the end of the second weft yarn are loosened to form a shearing portion, forming a local shearing shape with a three-dimensional sense. Since the shearing area is small, it is only used as a line decoration and does not affect the overall breathability and comfort of the upper. The upper as a whole is tightly interwoven with the first weft yarn and the warp yarn, which ensures the overall structural stability of the upper and is not easy to deform.

[0036] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0037] Please refer to Figures 1 to 3 The specific embodiment of the present invention relates to a processing technology of a breathable partially sheared woven shoe upper, comprising the following steps:

[0038] Step 1: Select the yarn and load it on the shuttle loom;

[0039] Yarn includes:

[0040] The first weft yarn 1 is 200-400D polyester high elastic yarn;

[0041] The second weft yarn 2 is 800-1000D polyester high elastic yarn;

[0042] Warp yarn 3 is 130-170D nylon fish silk;

[0043] Step 2: Design the upper, and input the upper design pattern into the shuttle loom, which weaves the upper according to the designed parameters to obtain the initial product of the woven upper.

[0044] The upper includes a sheared knitted area 4 and a non-sheared area 5;

[0045] The shearing weaving area 4 is a first weft yarn 1 and a second weft yarn 2 interwoven with the warp yarn 3 respectively;

[0046] The non-shearing area 5 is where only the first weft yarn 1 is interwoven with the warp yarn 3, and the second weft yarn 2 floats on the surface;

[0047] Step 3: Use a shearing device to cut the second weft yarn 2 at the edge of the sheared weaving area 4, so that the end of the second weft yarn 2 that does not participate in the interweaving retains a length of 2-4 mm, and the fibers of the yarn at the end of the second weft yarn 2 are loose, forming a sheared portion 41;

[0048] Step 4: The upper is shaped by a hot pressing and shaping device to obtain a breathable partially sheared woven upper.

[0049] In the above embodiment, the warp yarn 3 is made of nylon fish silk and the weft yarn is made of polyester high-elastic yarn, so that the upper has the advantages of elasticity, breathability and comfort. Among them, the first weft yarn 1 is interwoven with the warp yarn 3 throughout the whole process, while the second weft yarn 2 is only interwoven with the warp yarn 3 in the shearing weaving area 4, and the other non-shearing area 5 does not participate in the weaving, floating on the surface of the first weft yarn 1 and the warp yarn 3. After weaving to form the initial product of the upper, the second weft yarn 2 at the edge of the shearing weaving area 4 is cut by a shearing device, so that the end of the second weft yarn 2 that does not participate in the interweaving retains a length of 2-4mm, and the fibers of the yarn at the end of the second weft yarn 2 are loosened to form a shearing portion 41, forming a local shearing shape with a three-dimensional sense. Since the shearing area is small, it is only used as a line decoration and does not affect the overall breathability and comfort of the upper. The upper as a whole is tightly interwoven with the first weft yarn 1 and the warp yarn 3, which ensures the overall structural stability of the upper and is not easy to deform.

[0050] In the above embodiment, the first weft yarn 1 and the warp yarn 3 are involved in interweaving the entire upper. The first weft yarn is made of 200-400D fine yarn, and the warp yarn is made of 130-170D fine yarn, which can ensure the overall structural stability of the upper. The second weft yarn 2 is made of 800-1000D coarse yarn, so that when shearing is carried out later, its end can have more sufficient fiber looseness, forming a more three-dimensional shearing decorative effect.

[0051] As a preferred embodiment, the first weft yarn 1 is 300D polyester high-elastic yarn.

[0052] As a preferred embodiment, the second weft yarn 2 is 900D polyester high-elastic yarn.

[0053] As a preferred embodiment, the warp yarn 3 is 150D (0.12mm) nylon fish yarn.

[0054] As a preferred embodiment, in the shearing and weaving area 4 , the interlacing density of the first weft yarns 1 is greater than the interlacing density of the second weft yarns 2 .

[0055] In the above embodiment, since the role of the second weft yarn 2 is to participate in weaving in the sheared woven area 4, a three-dimensional sheared decorative effect with loose fibers is formed at the end of the second weft yarn 2 through subsequent shearing. The second weft yarn 2 participates in the interweaving only to play a role in fixing the middle part, so its interweaving density is less than the interweaving density of the first weft yarn 1, which can reduce its influence on the structural performance of the sheared woven area 4 of the upper.

[0056] As a preferred embodiment, two warp yarns 3 that are interlaced and close to each other are provided at the edge of the shearing and weaving area 4 .

[0057] In the above embodiment, the non-sheared area 5 is separated by two warp yarns 3 that are interlaced and close to each other at the edge of the sheared woven area 4, so that the sheared portions 41 at both ends of the second weft yarn 2 are stably fixed, ensuring the neatness and order of the sheared portions 41 and preventing the sheared portions 41 from falling off.

[0058] As a preferred embodiment, in step 2, the shuttle loom is an electronic rapier jacquard shuttle loom.

[0059] As a preferred embodiment, in step 3, the ends not involved in interweaving retain a length of 3 mm.

[0060] The specific embodiment of the present invention also relates to a breathable partially sheared woven shoe upper made by a processing technology of a breathable partially sheared woven shoe upper.

[0061] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
