Description

Technical Field

[0001] The invention relates to a fabric and a manufacturing method thereof, in particular to a knitted fabric, a shoe upper and a knitting method thereof. Background Art

[0002] The concave and convex three-dimensional structure on traditional knitted fabrics is usually obtained by padding or filling yarn. Among them, the three-dimensional knitted fabrics obtained by padding yarn are prone to yarn shedding in the padding layer, and the structural stability is relatively poor. The three-dimensional knitted fabrics obtained by filling yarn are difficult to accurately control parameters such as the thickness and density of the three-dimensional structure, and are prone to yarn accumulation or voids, affecting the presentation of the three-dimensional effect. In view of this, the inventors conducted in-depth research on the above-mentioned issues, and thus came up with this case. Summary of the Invention

[0003] The object of the present invention is to provide a knitted fabric, a shoe upper and a knitting method thereof, which are formed by connecting a plurality of sheets extending in directions away from the fabric body to the fabric body to form a knitted fabric with relatively good structural stability and three-dimensional effect.

[0004] In order to achieve the above object, the present invention provides the following technical solutions: A knitted fabric comprises a fabric body, wherein one side or both sides of the fabric body are provided with a thickened area, each of the thickened areas has a plurality of sheets extending in a direction away from the fabric body, one end of each sheet is woven and connected to the fabric body as a whole, and the other end is suspended.

[0005] As an improvement of the present invention, in the same thickened area, the heights of the sheets or parts of the sheets are different from each other.

[0006] As an improvement of the present invention, the fabric body is a single-layer fabric body, a double-layer fabric body or a multi-layer fabric body.

[0007] As an improvement of the present invention, the sheet is a single-layer sheet, a double-layer sheet or a multi-layer sheet.

[0008] As an improvement of the present invention, each of the sheet bodies is connected to the fabric body through weaving through a connecting structure or a transition structure.

[0009] As an improvement of the present invention, in the same thickened area, two adjacent sheets are woven and connected as one.

[0010] As an improvement of the present invention, at least a portion of the sheets arranged on the upper and lower sides of the fabric in the same thickened area are staggered or staggered in the vertical direction.

[0011] A knitted shoe upper adopts the knitted fabric.

[0012] A method for knitting a knitted fabric, which is performed using a flat knitting machine. The flat knitting machine has at least two needle beds, wherein the two needle beds are a first needle bed and a second needle bed. A fabric body is knitted on the first needle bed. In areas where the fabric body needs to be thickened, a sheet is knitted on the second needle bed using an empty needle cast-on method. After the sheet is knitted, part of the loops on the corresponding sheet are transferred and connected to the fabric body by means of a transfer needle. The knitting is then repeated to obtain a plurality of sheets, and the sheets are arranged together.

[0013] As an improvement of the present invention, the yarn used for weaving the fabric body is different from the yarn used for weaving the sheet body.

[0014] As an improvement of the present invention, after the sheet is knitted, the connecting structure or transition structure is first knitted on the second needle bed, and then the second needle bed coils on the corresponding weaving row of the connecting structure or transition structure are transferred to the first needle bed, and then the yarn used to knit the sheet is used to perform dense needle knitting on the first needle bed.

[0015] As an improvement of the present invention, after completing the knitting and connection of one sheet, the coils on the first needle bed are transferred to the second needle bed, leaving the first needle bed free for knitting a new sheet.

[0016] As an improvement of the present invention, after the sheet is knitted, the first needle bed coil on the corresponding weaving row is first moved horizontally by more than one needle, and then the needle is transferred to the second needle bed. Then, the second needle bed coil on the corresponding weaving row is moved horizontally by more than one needle, and then the needle is transferred to the first needle bed.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects: 1. By connecting multiple sheets arranged in sequence to the fabric body to form a concave and convex three-dimensional structure, the sheets are not easy to fall off, the structural stability is relatively good, and there will be no yarn accumulation or voids, which can better present a three-dimensional effect.

[0018] 2. The solution adopted by the present invention can form various complex three-dimensional shapes in the thickened area by precisely controlling the height and density of the sheet, thereby meeting the demand for unique shapes of high-end knitted products. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 The cross-sectional structure of the knitted fabric in Example 1 is shown Figure 1 ; Figure 2 The cross-sectional structure of the knitted fabric in Example 1 is shown Figure 2 ; Figure 3 is a weaving diagram of the weaving method in Example 2; Figure 4 This is the weaving diagram of the weaving method in Example 3.

[0020] The corresponding markings in the figure are as follows: 10- fabric body; 20- sheet body; DETAILED DESCRIPTION The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the terms "first" and "second" in the present invention are used to distinguish different objects rather than to describe a specific order.

[0021] Example 1 This embodiment provides a knitted fabric, which can be directly woven into the shape of a shoe upper, or formed into the shape of a shoe upper by cutting. That is, this embodiment essentially also provides a knitted shoe upper using the above-mentioned knitted fabric.

[0022] like Figure 1-Figure 2 As shown, the knitted fabric provided in this embodiment includes a fabric body 10, and the fabric body 10 is a single-layer fabric body, a double-layer fabric body or a multi-layer fabric body, which can be selected according to actual needs.

[0023] One side or both sides of the fabric body 10 are provided with a thickened area for forming a concave-convex three-dimensional structure of the knitted fabric. In other words, the thickened area can be provided on only one side of the fabric body 10 (see Figure 1 ), or thickened areas can be provided on both sides of the fabric body 10 at the same time (see Figure 2 ), in this embodiment, a thickened area is provided on both sides of the fabric body 10 as an example. Furthermore, there may be one or more thickened areas on the same side of the fabric body 10. When there is only one thickened area, it may occupy only a portion of the fabric body 10 or cover the entire side of the fabric body 10. In this embodiment, the minimum knittable unit of a single sheet 20 is 2 stitches in width and 1 stitch in height.

[0024] For ease of description, in this embodiment, the upper and lower positional relationship of the fabric body 10 is described in a horizontally arranged state, with the upper surface of the fabric body 10 being the surface layer of the fabric body 10 and the lower surface being the lower layer of the fabric body 10.

[0025] Preferably, when thickened areas are respectively provided on both sides of the fabric body 10, if the positions of the thickened areas on both sides of the fabric body 10 are arranged corresponding to each other, at least a part of the sheets 20 arranged on the upper and lower sides of the fabric body 10 are staggered or arranged with staggered needles in the vertical direction, that is, staggered or staggered arrangement. It should be noted that when the sheet 20 on the surface layer is knitted on the 1st / 3rd / 5th / 7th weaving column from left to right at the needle position, its empty needles are 2 / 4 / 6 / 8, and the corresponding bottom sheet 20 on the back can be knitted at the position where the empty needle position of the corresponding surface layer is the 2nd / 4th / 6th / 8th weaving column needle position, or the back knitting needle position is the 2nd / 4th / 6 / 8th weaving column needle position, or the back knitting needle position is the 2nd / 3rd / 4 / 6 / 8th weaving column needle position.

[0026] Each thickened area has multiple flaps extending away from the fabric body 10. The flaps located in the same thickened area abut one another, creating a tight fit. When the fabric body 10 is arranged horizontally, the flaps 20 located on the upper side of the fabric body 10 extend upward, while the flaps 20 located on the lower side extend downward. The flaps 20 can be single-layer, double-layer, or multi-layer. One end of each flap 20 is integrally woven and connected to the fabric body 10, while the other end is suspended, meaning the end of the flap 20 facing away from the fabric body 10 is not connected to the fabric body 10. This allows most flaps 20 to stand upright (i.e., generally perpendicular to the fabric body 10) while being supported by the flaps 20 on either side, effectively creating a three-dimensional time-lapse effect. While a gap between adjacent flaps 20 at the ends connected to the fabric body 10 is permitted, this gap is typically much smaller than the height of the flap 20.

[0027] It should be noted that, in each embodiment below this embodiment, the direction of the line connecting one end of the sheet 20 connected to the fabric body 10 and the corresponding other end is the height direction of the sheet 20, that is, the greater the height of the sheet 20, the higher the height of the three-dimensional structure formed by it. The height here refers to the distance between one end of the sheet 20 away from the fabric body 10 and the other end when the sheet 20 and the fabric body 10 are arranged vertically.

[0028] Preferably, in the same thickened area, the heights of the sheets 20 or parts of the sheets 20 are different from each other, so that the thickened area can form a concave-convex effect with height differences, and a shoe upper with a delicate three-dimensional texture or a component with a unique spatial shape can be produced.

[0029] Preferably, each sheet 20 is woven integrally with the fabric body 10 through a bird's-eye weave to improve connection stability and prevent it from falling off. The bird's-eye weave is a conventional knitted weave and will not be described in detail here.

[0030] Preferably, in the same thickened area, two adjacent sheets 20 are woven and connected as one body, which can avoid collapse and further enhance the three-dimensional effect.

[0031] Example 2 This embodiment provides a knitting method for a knitted fabric, which can be used to knit the knitted fabric provided in Example 1.

[0032] The knitting method of the knitted fabric is carried out using an existing flat knitting machine, which has at least two needle beds arranged in sequence, wherein the two adjacent needle beds are respectively the first needle bed and the second needle bed. During knitting, the fabric body 10 is knitted on the first needle bed, and in the area where the fabric body 10 needs to be thickened, the sheet 20 is knitted on the second needle bed by using an empty needle method, wherein the yarn used for knitting the fabric body 10 is different from the yarn used for knitting the sheet 20. In this embodiment, the yarn used for knitting the fabric body 10 is polyester high-elastic spandex double-covered yarn, and the yarn used for knitting the sheet 20 is polyester high-elastic yarn, wherein the polyester high-elastic yarn and the polyester high-elastic spandex double-covered yarn are both yarns that can be purchased directly from the market and will not be described in detail here. After the sheet 20 is knitted, the corresponding part of the coils on the sheet 20 are transferred and connected to the fabric body 10 by means of a needle transfer method, and then the knitting is repeated to obtain multiple sheets 20, and each sheet 20 is arranged together in sequence.

[0033] The specific fabric structure of the fabric body 10 and the sheet 20 can be selected according to actual needs. The minimum weavable unit size of a single sheet 20 is 2 needle positions in width and 1 needle position in height. Preferably, Figure 3 As shown, the specific knitting steps of this embodiment are as follows: The first weave is a polyester high-elastic yarn knitted with open needles and spacer needles; the second weave is a polyester high-elastic yarn knitted with open needles and spacer needles, which is used to form a close-knit surface knit with the first weave; the third to eighth weaves are repeated weaves of the first and second weaves, and the sheet 20 is obtained by weaving the first to eighth weaves. It should be noted that the height of the sheet 20 (i.e., the height of the three-dimensional structure) is proportional to the number of weaves of the sheet 20, and the greater the number of weaves, the greater the height.

[0034] The 9th knitting row is a close-knitting pattern using a polyester high-elasticity spandex double-covered yarn. The 10th and 11th knitting rows are a bird's-eye pattern using a polyester high-elasticity spandex double-covered yarn, which is used to initially connect the sheet 20 to the fabric body 10. The 12th and 13th knitting rows transfer the stitches from the second needle bed in the corresponding row to the first needle bed. The 14th knitting row is a close-knitting pattern using a polyester high-elasticity spandex double-covered yarn. In other words, after the sheet 20 is knitted, a bird's-eye pattern is first knitted on the second needle bed. The stitches from the second needle bed in the corresponding row of the bird's-eye pattern are then transferred to the first needle bed. Finally, the yarn used to knit the sheet 20 is used to knit a close-knit pattern on the first needle bed.

[0035] The 15th and 16th knitting rows are the transfer operations of transferring the corresponding stitches on the first needle bed to the second needle bed, transferring the fabric body 10 to the bottom layer, and freeing up the first needle bed for knitting a new sheet 20. That is, after completing the knitting of one sheet, the stitches on the first needle bed are transferred to the second needle bed, and the first needle bed is freed up for knitting the new sheet 20.

[0036] The 1st to 16th weaving rows mentioned above are the minimum cycle units of the thickened area, and the 17th to 32nd weaving rows are repeated weaving of the 1st to 16th weaving rows, which will not be repeated here.

[0037] Example 3 This embodiment provides a knitting method for a knitted fabric, which can be used to knit the knitted fabric provided in Example 1.

[0038] The knitting method of the knitted fabric is carried out using an existing flat knitting machine, which has at least two needle beds arranged in sequence, wherein the two adjacent needle beds are respectively the first needle bed and the second needle bed. During knitting, the fabric body 10 is knitted on the first needle bed, and in the area where the fabric body 10 needs to be thickened, the sheet 20 is knitted on the second needle bed by using an empty needle method, wherein the yarn used for knitting the fabric body 10 is different from the yarn used for knitting the sheet. In this embodiment, the yarn used for knitting the fabric body 10 is polyester high-elastic spandex double-covered yarn, and the yarn used for knitting the sheet 20 is polyester high-elastic yarn, wherein the polyester high-elastic yarn and the polyester high-elastic spandex double-covered yarn are both yarns that can be purchased directly from the market and will not be described in detail here. After the sheet 20 is knitted, the corresponding part of the coils on the sheet 20 are transferred and connected to the fabric body 10 by the needle transfer method, and then the knitting is repeated to obtain multiple sheets 20, and each sheet 20 is arranged together in sequence.

[0039] The specific fabric structure of the fabric body 10 and the sheet 20 can be selected according to actual needs. The minimum weavable unit size of a single sheet 20 is 2 needle positions in width and 1 needle position in height. Preferably, Figure 4 As shown, the specific knitting steps of this embodiment are as follows: The first weaving line is to knit the polyester high elastic yarn with the regular spaced needles for the surface knitting and the bottom knitting. Figure 4 The knitting action shown in the 2nd to 5th knitting rows of the 1st knitting row is as follows; the 2nd knitting row is a regular knitting of bottom knitting spacer needles and surface knitting spacer needles for polyester high elastic yarn, that is, Figure 4 The knitting operation of the second row of the second row is shown in the second to fifth rows; the third to eighth rows are repeated knitting of the first and second rows, and the sheet 20 is obtained by knitting rows 1 to 8. It should be noted that the height of the sheet 20 (i.e., the height of the three-dimensional structure) is proportional to the number of knitting rows of the sheet 20, and the greater the number of knitting rows, the greater the height.

[0040] The 9th knitting row is a needle moving action of moving the first needle bed coil of the corresponding knitting column to the left by one needle and then transferring the needle to the second needle bed; the 10th knitting row is a needle moving action of moving the second needle bed coil of the corresponding knitting column to the left by one needle and then transferring the needle to the first needle bed; through the knitting actions of these two knitting rows, the needle moving action of moving the sheet 20 to the fabric body 10 can be realized, that is, after the knitting of the sheet 20 is completed, first move the first needle bed coil on the corresponding knitting column horizontally by more than one needle, and then transfer the needle to the second needle bed, and then move the second needle bed coil on the corresponding knitting column horizontally by more than one needle, and then transfer the needle to the first needle bed.

[0041] The 11th weaving line is a regular weaving of polyester high elastic spandex double covered yarn with surface weaving space needle and bottom weaving space needle, that is, Figure 4 The knitting action of the 1st to 4th columns of the 11th knitting row; the 12th knitting row is a regular knitting of the bottom knitting spacer needle and the surface knitting spacer needle for the polyester high elastic spandex double covered yarn, that is, Figure 4 The 12th row is knitted from the 1st to the 4th row; the 13th and 14th rows are repeated knitting of the 11th and 12th rows. The fabric body 10 is obtained by knitting the 11th to the 14th rows, wherein the empty needle positions on the fabric body 10 are to leave space for knitting the sheet 20.

[0042] The 1st to 14th weaving rows mentioned above are the minimum cycle units of the thickened area, and the 14th to 28th weaving rows are repeated weaving of the 1st to 14th weaving rows, which will not be repeated here.

[0043] It should be noted that the yarn used in the embodiment is only one of the cases. For example, the braided yarn used may be elastic yarn or high shrinkage yarn. The braiding height of the sheet 20 can be braided according to the actual three-dimensional effect required.

[0044] Example 4 The knitted fabric provided in this embodiment includes a fabric body 10 and a sheet 20 disposed thereon. The minimum knittable unit size of a single sheet 20 is 2 stitches in width and 1 stitch in height. The knitted fabric provided in this embodiment is further improved on the basis of Example 1, as described below: While maintaining a width of two needle positions, as the knitting height (i.e., the dimension extending in the height direction) increases, the required yarn support performance must be correspondingly enhanced. The better the support performance of the yarn, the higher the height of the sheet 20 that can be formed and maintained. This is because the increase in the overall knitting area of the sheet 20 leads to an increase in weight. If the yarn support is insufficient, it is prone to falling. It should be noted that depending on the material properties of the selected yarn and the actual knitting height, a single sheet 20 can present a three-dimensional effect. However, under certain conditions, when knitting yarn with a certain degree of shrinkage or good resilience, the free edge at the top of the sheet 20 (away from the end connected to the fabric body 10) may curl.

[0045] To effectively organize the multiple panels 20 and enhance structural stability, the minimum spacing between adjacent panels 20, perpendicular to the weaving direction of the fabric body 10, should be at least one row of stitches. When there are three or more panels 20 arranged sequentially, the central panel 20 receives lateral support (or restraint) from the panels 20 on its left and right. This restraint effect allows the central panel 20 to exhibit a more pronounced upright effect and overall support compared to the panels 20 at the ends of the arrangement.

[0046] In the same thickened area, the sheets 20 are arranged in a gradient array, and the spacing between the sheets increases or decreases linearly from one end to the other along the length or width of the fabric, forming a visual gradient effect.

[0047] When the woven yarn used for the sheet is made of a certain material, the surface of the sheet 20 has electrostatic adsorption ability, and the adjacent sheets 20 are attracted to each other through electrostatic adsorption and maintain an upright state (because the sheet 20 has a certain thickness and the edge of one end of the sheet 20 away from the fabric body 10 will form a curl, thereby occupying a certain space, if the sheets 20 are too dense, the comfort is not so significant, and if the sheets 20 are too sparse, they cannot be adsorbed to each other), thereby forming a stable three-dimensional thickening effect.

[0048] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the existing technology, and all of these modifications fall within the scope of protection of the present invention.
