Description

Technical Field

[0001] The invention relates to the technical field of shoe uppers, in particular to a shoe upper with tuck holes, a shoe and a knitting method thereof. Background Art

[0002] In modern footwear manufacturing, the design of the upper not only impacts aesthetics but also directly affects wearing comfort. Tuck hole technology, a common knitting process, is widely used in shoe upper manufacturing to enhance the upper's three-dimensional appearance and breathability. However, the spacing between traditional tuck holes is narrow, making them less visually appealing and limiting their ventilation efficiency, resulting in mediocre ventilation. Therefore, further optimizing the tuck hole structure to enhance the performance of the upper is crucial. Based on this, the inventors conducted research and proposed this proposal. Summary of the Invention

[0003] The present invention provides a shoe upper with tuck holes, a shoe and a knitting method thereof, which overcome the deficiencies described in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A shoe upper with tuck holes comprises a surface layer, a bottom layer, and a plurality of first knitting areas on the surface layer and / or a plurality of second knitting areas on the bottom layer, wherein the first knitting areas and / or the second knitting areas are provided with tuck holes, and a plurality of slit holes are provided around the tuck holes on the first knitting areas and / or the second knitting areas.

[0006] A preferred technical solution: The number of knitting loops between adjacent tuck holes in the first knitting area of the surface layer and / or the second knitting area of the bottom layer is lower than the number of loops in the non-first knitting area of the upper. The tuck holes are made tighter by reducing the number of loops or adjusting the knitting density, thereby widening the hole spacing of the knitted tuck holes.

[0007] A preferred technical solution: the tuck holes are knitted by continuous tucks on the same layer in the longitudinal direction, and the number of rows of continuous tucks on the same layer in the longitudinal direction is not less than 3 rows.

[0008] A preferred technical solution: the slit holes are formed by hollow needle knitting, the number of knitting loops between adjacent slit holes is lower than the number of loops in the non-first knitting area of the upper surface layer and / or the number of knitting loops between adjacent slit holes is lower than the number of loops in the non-second knitting area of the lower layer of the upper, and the tuck holes are integrated at the bending and deformation of the surface layer and / or the lower layer. Since the open large hole structure in the tuck holes has a large open hollow area, the hardness of the upper is indirectly reduced, making the upper softer and reducing the discomfort caused by local hardness.

[0009] A preferred technical solution: the coil density of the knitting area of the non-tuck holes and slit holes in the first knitting area is less than the coil density of the non-first knitting area of the upper, and / or the coil density of the knitting area of the non-tuck holes and slit holes in the second knitting area is less than the coil density of the non-second knitting area of the upper.

[0010] A preferred technical solution: the positions of the tuck holes of the first knitting area of the surface layer and the second knitting area of the bottom layer at least partially overlap with each other or do not overlap at all.

[0011] After the upper and sole are connected to form a finished shoe, when a user walks in the finished shoe, the toes of the foot will bend to a certain extent due to the need to walk, and the upper will also bend at the corresponding position. After long-term wear of the finished shoe, a crease will appear at the end of the tongue opening of the upper. If the upper is too hard or difficult to bend, it can easily cause discomfort. The tuck hole upper of the present invention has a plurality of tuck holes concentrated at this crease, which improves the bending effect of the upper and can prevent the formation of creases on the upper to a certain extent.

[0012] A preferred technical solution: the tuck holes are concentrated in the local breathable areas of the surface layer and / or the bottom layer. By reasonably arranging the positions of the tuck holes on the upper, the breathability of the corresponding local areas of the upper is improved.

[0013] A preferred technical solution: the width of the tuck hole is in the range of 0.5mm-10mm.

[0014] A preferred technical solution: The width of the tuck holes is within the range of 1.5mm-4mm. In this case, the tuck holes are widely spaced. Since the tuck holes form an open large-pore structure on the upper, they can provide a larger ventilation channel for the upper. The gap holes around the open large-pore structure can help provide more ventilation channels, further increasing the total ventilation area, improving the ventilation effect of the upper, and facilitating heat dissipation for the feet to keep them dry.

[0015] A preferred technical solution: the slit holes are arranged symmetrically or asymmetrically on both sides of the tuck hole in a non-vertical direction.

[0016] A shoe adopts the above-mentioned upper with tuck holes.

[0017] A method for knitting a tuck eyelet shoe upper comprises the following steps:

[0018] Selecting yarn for knitting the upper, controlling the tuck holes of the yarn in the first knitting area of the top layer and / or the second knitting area of the bottom layer to gradually form the tuck holes by continuous front knitting and back tight tucks in the same layer in the longitudinal direction and spacer knitting, wherein the number of continuous tucks in the same layer in the longitudinal direction is not less than 3 rows, and at least one type of yarn is selected;

[0019] The number of knitted loops between adjacent tuck holes on the first knitted area of the surface layer is less than the number of loops in the non-first knitted area of the upper; and / or the number of knitted loops between adjacent tuck holes on the second knitted area of the bottom layer is less than the number of loops in the non-second knitted area of the upper;

[0020] and / or the coil density of the knitting area of the non-tuck holes and the slit holes in the first knitting area is smaller than the coil density of the non-first knitting area of the upper;

[0021] and / or the loop density of the knitting area of the non-tuck holes and the slit holes in the second knitting area is smaller than the loop density of the non-second knitting area of the upper;

[0022] The yarn weaving is controlled to connect the surface layer and the bottom layer, and the surface layer and the bottom layer in the non-tuck hole and gap hole areas are continuously knitted until a complete upper is formed.

[0023] A preferred technical solution: two or more yarns are selected, and the two or more yarns are of the same kind or different kinds.

[0024] A preferred technical solution also includes the following steps: the tuck eyelet upper is subjected to post-processing after knitting, and the post-processing method is a high-temperature heat setting method of 120-160°C.

[0025] By adopting the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In the present invention, wide-spaced tuck holes with a preferred width range of 0.5mm-10mm are provided to form an open large-pore structure on the upper, providing a larger ventilation channel for the upper. The slit holes surrounding the open large-pore structure can also provide more ventilation channels, further increasing the total ventilation area and improving the overall ventilation effect of the upper.

[0027] 2. The tuck holes in the present invention can be centrally arranged at the bends and deformations of the upper, making the upper softer and reducing discomfort caused by local hardness.

[0028] 3. The tuck holes in the shoe upper of the present invention can be provided with tuck holes according to needs, and the tuck holes on the surface layer can be combined to design more diverse patterns to meet the personalized needs of consumers. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Example 1

[0040] like Figures 1-4 As shown, this embodiment provides a shoe upper with loop holes, including a surface layer 1, a bottom layer 2, and several first knitting areas 11 opened on the surface layer 1 and / or several second knitting areas 21 opened on the bottom layer 2, and the first knitting areas 11 and / or the second knitting areas 21 are provided with loop holes 3, and the width of the loop holes 3 ranges from 0.5mm to 10mm. The loop holes 3 constitute an open large hole structure on the shoe upper 100, and several slit holes 32 are arranged around the loop holes on the first knitting areas 11 and / or the second knitting areas 21.

[0041] The width of the tuck holes 3 is within the range of 1.5mm-4mm. In this case, the tuck holes 3 are widely spaced. Since the tuck holes 3 form an open, large-pore structure on the upper 100, they provide larger ventilation channels for the upper 100. The slit holes 32 surrounding the open, large-pore structure further provide more ventilation channels, further increasing the total ventilation area and improving the ventilation of the upper 100, which helps dissipate heat and keep the foot dry. The width of the tuck holes 3 can be selected from the edge values and point values within the range of 1.5mm-4mm, such as 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, or 1.6mm, 1.7mm, etc. The larger the value, the greater the lateral width of the tuck holes 3.

[0042] The slit holes 32 may be provided around the tuck hole 3 , or may be arranged symmetrically or asymmetrically on both sides of the tuck hole 3 in a non-vertical direction.

[0043] The tuck holes 3 can be provided only on the surface layer 1, or only on the bottom layer 2, or on both the surface layer 1 and the bottom layer 2. The tuck holes 3 on the surface layer 1 can be combined to form a variety of patterns to meet the personalized needs of consumers.

[0044] Example 2

[0045] like Figure 5 As shown, this embodiment provides a shoe upper with tuck holes. The difference between this embodiment and embodiment 1 is that:

[0046] The number of knitting coils between adjacent tuck holes 3 on the first knitting area 11 of the surface layer 1 and / or the second knitting area 21 of the bottom layer is lower than the number of coils in the non-first knitting area 11 of the upper. The tuck holes 3 make the plain layer (plain weave) between the non-tuck holes 3 and the slit holes 32 in the area tighter by reducing the number of coils in the first knitting area 11 and / or the second knitting area 21 or adjusting the knitting density of the first knitting area 11 and / or the second knitting area 21, thereby widening the hole spacing of the knitted tuck holes.

[0047] Furthermore, the tuck holes 3 are knitted by continuous tucks in the same layer in the longitudinal direction, and the number of rows of continuous tucks in the same layer in the longitudinal direction is not less than 3. The more rows there are, the more obvious the wide spacing effect of the tuck holes 3 is.

[0048] Furthermore, the slit holes 32 are formed by open needle knitting, and the number of knitted loops between adjacent slit holes 32 is less than the number of loops in the non-first knitting area 11 of the upper layer 1 of the shoe upper 100, and / or the number of knitted loops between adjacent slit holes is less than the number of loops in the non-second knitting area 21 of the bottom layer 2 of the shoe upper 100. For example, if the number of loops per square centimeter of the upper layer 1 and / or bottom layer 2 is 10, and the number of loops per square centimeter in the first knitting area 11 and the second knitting area 21 is 6, the tuck holes 3 and slit holes 32 per square centimeter are pulled outward due to the small number of loops, resulting in a larger natural opening.

[0049] Furthermore, the tuck holes 3 are integrated at the bending deformation portion 101 of the surface layer 1 and / or the bottom layer 2. Since the open large hole structure in the tuck holes 3 has a large open hollow area, the hardness of the upper 100 is indirectly reduced, making the upper 100 softer and reducing the discomfort caused by local excessive hardness.

[0050] The hole positions of the tuck holes 3 and the slit holes 32 in the first woven area 11 of the surface layer 1 and the second woven area 21 of the bottom layer 2 can be completely overlapped to achieve the maximum breathability effect, or partially overlapped, or not overlapped, such as the tuck holes 3 of the surface layer 1 corresponding to the non-second woven area 21 of the bottom layer 2 (similarly, the second woven area 21 of the bottom layer 2 can also correspond to the position of the non-first woven area 11 of the surface layer 1).

[0051] Example 3

[0052] like Figure 1 As shown, this embodiment provides a shoe that utilizes the upper with tuck holes described in Example 1 or Example 2. The upper 100 is connected to the sole via a colloid to form the finished shoe. Tuck holes 3 are concentrated in localized breathable areas 102 of the surface layer 1 and / or the bottom layer 2, enhancing ventilation in corresponding localized areas of the upper 100. Localized breathable areas 102 are typically located at the toe box 103 and side 104 of the shoe, improving ventilation at the front and sides of the foot.

[0053] When the tuck holes 3 of the top layer 1 and the bottom layer 2 are located in the same position on the upper 100, that is, the tuck holes 3 on the upper and lower layers are interconnected, the upper 100 achieves optimal ventilation. If only the top layer 1 or only the bottom layer 2 is provided with tuck holes 3, the ventilation of the corresponding layer where the tuck holes 3 are located is improved, while the ventilation of the other layer is moderate. This ensures that the overall upper 100 is both breathable and warm. The layer without tuck holes 3 can prevent particulate matter from entering the shoe through the upper 100.

[0054] Example 4

[0055] This embodiment provides a method for knitting a tuck eyelet shoe upper, comprising the following steps:

[0056] Selecting yarn for knitting the upper, controlling the yarn to gradually form the tuck holes 3 in the first knitting area 11 of the surface layer 1 and / or the second knitting area 21 of the bottom layer 2 by continuous front knitting and back tight tucks in the same layer in the longitudinal direction and spacer knitting, wherein the number of continuous tucks in the same layer in the longitudinal direction is not less than 3 rows, and at least one type of yarn is selected;

[0057] The number of knitted loops between adjacent tuck holes in the first knitting area 11 of the surface layer 1 is lower than the number of loops in the non-first knitting area 11 of the upper; and / or the number of knitted loops between adjacent tuck holes 3 in the second knitting area 21 of the bottom layer 2 is lower than the number of loops in the non-second knitting area 21 of the upper;

[0058] and / or the coil density of the knitting area of the non-tuck holes and the slit holes 32 of the first knitting area 11 is smaller than the coil density of the non-first knitting area of the upper;

[0059] and / or the coil density of the knitting area of the non-tuck holes 3 and the slit holes 32 of the second knitting area 21 is smaller than the coil density of the non-second knitting area of the upper;

[0060] The yarn is controlled to weave and connect the surface layer 1 and the bottom layer 2, and the surface layer 1 and the bottom layer 2 in the non-tuck holes 3 and the slit holes 32 areas are continuously weaved until a complete shoe upper is formed.

[0061] Furthermore, two or more yarns are selected, and the two or more yarns are the same type of yarns or different types of yarns.

[0062] Furthermore, the following steps are included: the tuck eyelet 3 shoe upper 100 is subjected to post-processing after knitting is completed, and the post-processing method is a high-temperature heat setting method of 120-160°C.

[0063] The yarn is preferably a multifilament material such as polyester multifilament or nylon multifilament, but can also be any other yarn that can be knitted. Regardless of whether the yarn used to knit the shoe upper 100 includes a thermo-fusible thread, high-temperature heat setting allows the shoe upper 100 to fully shrink under the heat, achieving a suitable upper condition. For shoe uppers 100 using thermo-fusible threads, high-temperature treatment causes the thermo-fusible threads to melt and bond to the interior of the shoe upper, thereby enhancing the strength of the shoe upper 100.

[0064] The following uses yarn A and yarn B to weave the upper as an example to further explain the weaving process of the upper. Figure 6 :

[0065] Yarn A and yarn B are both made of polyester high-elastic yarn;

[0066] The first knitting row is to use yarn A for the top knitting and empty needles for spacer knitting, and some knitting needles are used for front knitting and back tight tuck knitting;

[0067] The second knitting row is to knit the B yarn into full stitches;

[0068] The third knitting row is the A yarn for the top knitting and the empty needles for the spacer knitting. The spacer needle position is offset by 1 needle from the first knitting row, and the front knitting and the back tightness tuck knitting are continued at the tuck needle position of the first row.

[0069] The 4th knitting row is to knit the B yarn into full stitches;

[0070] Rows 5 to 12 are repeats of rows 1 to 4;

[0071] The longitudinal continuous front knitting and back tight tuck will form a tuck hole. The spacer knitting on the left and right of the tuck hole is to reduce the surface loops and make the surface layer 1 more compact, thereby widening the hole spacing of the tuck hole 3.

[0072] The 13th knitting row is to knit the yarn A on the face stitches;

[0073] The 14th knitting row is knitting the full stitches with yarn B;

[0074] The 1st to 14th rows are the smallest cycle unit, and the 15th to 28th rows are repeated weavings of the 1st to 14th rows.

[0075] The above-described weaving method can produce a shoe upper 100 with unique breathability and aesthetics. The shoe upper 100 manufactured using this process maintains excellent breathability while also improving its structural stability. This process is applicable to various types of shoe uppers 100, including athletic shoes and casual shoes, and has broad application prospects.

[0076] Example 5

[0077] like Figure 5 As shown, when the tuck eyelet 3, the smallest unit of the knitting rule (a unit area of 1 weaving column and 3 weaving rows during the knitting process), is knitted with six corresponding slit holes 32 around it, the number of corresponding regular stitches is 15. In particular, when the tuck eyelet 3 is knitted in a minimum unit of 1 weaving column and at least 3 weaving rows, the number of weaving columns does not increase, only the number of weaving rows. For example: 1 weaving column and 3 weaving rows, 1 weaving column and 4 weaving rows, 1 weaving column and 5 weaving rows, and so on.

[0078] It should be noted that the adjacent in the adjacent tuck holes 3 and adjacent slit holes 32 in the specification refers to the same surface layer or the same bottom layer, and the adjacent weaving between the surface layer and the bottom layer is not referred to in this article.

[0079] In the above embodiment, Figure 1 The marked tuck hole 3 corresponds to the attached Figure 6 The knitting action of the 12th knitting row and the 25th knitting line, the gap hole 32 formed by the empty needle knitting corresponds to the attached Figure 6 The knitting action of the 14th weaving column and the 1st weaving row.

[0080] Since the adjacent knitting positions of the tuck holes 3 and the slit holes 32 in the first knitting area 11 and / or the second knitting area 21 have more inward tension, the two sides of the holes are naturally stretched, so that the spacing between the holes is greater, and a larger open area is naturally formed.

[0081] Example 6

[0082] The slit holes 32 arranged around the tuck hole 3 can be arranged regularly or irregularly on both sides of the tuck hole 3. It is just that the hole shape of the tuck hole is regular or irregular. When the slit holes 32 are arranged in the vertical direction of the tuck hole 3, the number of their arrangement will affect the stretching length of the tuck hole 3 in the vertical direction. However, in actual product application, the lateral stretching force generated by the arranged slit holes 32 on both sides and the ordinary coil will be greater than the stretching force in the vertical direction, so it will not affect the opening width of the tuck hole 3.

[0083] The best solution is that the number of slit holes 32 in the vertical direction of the tuck hole 3 is less than the number of slit holes 32 on both sides, or there is no arrangement of slit holes 32 in the vertical direction, so that the opening width and shape of the tuck hole 3 are more beautiful.

[0084] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of the present invention. In other words, equivalent changes and modifications made according to the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
