Description

Technical Field

[0001] This application relates to the field of textile fabric technology, and in particular to a knitted fabric with radial elongated holes, a method for manufacturing the same, and a knitted shoe upper based on the knitted fabric. Background Technology

[0002] Traditional flyknit uppers with warp perforations typically involve first weaving perforations in the weft direction, then using the weft direction as the warp to create the warp perforation pattern. This process is time-consuming and can affect the appearance of other normal knit textures. Some existing solutions use a partial knitting technique; when knitting multiple warp perforations consecutively, the yarn connects from the end of one perforation's edge to the beginning of another, leaving loose threads within the warp perforations. These loose threads affect the perforation size, breathability, and aesthetics. Summary of the Invention

[0003] To address one or more of the aforementioned technical problems in the prior art, this application discloses a knitted fabric and a method for manufacturing the same, as well as a knitted shoe upper. The knitted fabric has smooth edges on its radially elongated holes and no loose threads.

[0004] The first aspect of this application provides a knitted fabric including at least one radial elongated hole; wherein the radial elongated hole is formed by misalignment of adjacent but not completely adjacent first and second fabric regions, and is surrounded by the first and second fabric regions; wherein the adjacent boundary of the first and second fabric regions is hidden on the back edge of the first and / or second fabric regions by loop knitting or tuck knitting hanging yarn based on the floating yarn formed by the misalignment.

[0005] According to some embodiments of this application, the length of the radial elongated hole is determined by the number of weave rows in the first fabric region and the second fabric region.

[0006] According to some embodiments of this application, the first fabric region and the second fabric region are each independently a single-layer fabric or a multi-layer fabric.

[0007] According to some embodiments of this application, when the first fabric region and / or the second fabric region is a single-layer fabric, the side edges of the first fabric region and / or the second fabric region surrounding the radial elongated hole are rolled inward.

[0008] According to some embodiments of this application, when the first fabric region and / or the second fabric region is a multilayer fabric, the number of weave rows of the portion of the side edge of the first fabric region and / or the second fabric region that belongs to the single-layer main fabric determines the width of the radial elongated hole.

[0009] According to some embodiments of this application, the width of the radial elongated hole can be adjusted by shifting loop weaving.

[0010] According to some embodiments of this application, the radial elongated hole is a full-through hole or a semi-through hole.

[0011] According to some embodiments of this application, the first fabric region and the second fabric region are formed by partial weaving or multi-yarn-head side-weaving.

[0012] The second aspect of this application provides a method for manufacturing a knitted fabric as described above, the method comprising: step-knitting a first fabric region and a second fabric region; the first fabric region and the second fabric region being adjacent but not completely adjacent at the edges; misaligning the first fabric region and the second fabric region to form the radial elongated hole, and knitting the adjacent boundary of the first fabric region and the second fabric region in loops or tucks based on the floats formed by the misalignment, with the hanging yarn hidden on the back edge of the first fabric region and / or the second fabric region.

[0013] A third aspect of this application provides a knitted shoe upper, the knitted shoe upper comprising the knitted fabric described above.

[0014] The radially elongated holes in the knitted fabric provided in this application have smooth edges, are not easily unraveled, and possess excellent stability. Furthermore, they are less restricted in terms of appearance, and the hole size can be adjusted according to different practical needs. Unlike traditional small holes, the radial holes in this application have a strong visual impact, providing a powerful visual stimulus. In addition, the radial holes in this application do not have floats; the floats are concealed on one side of the hole edge, making the holes clean and transparent without obstruction. Moreover, the radial holes in this application offer greater variability and control over their appearance, resulting in a greater diversity in the number and placement of holes compared to traditional mesh weaving, with fewer limitations.

[0015] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Detailed Implementation

[0017] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0019] As described in the background section, the traditional radial elongated hole weaving process is time-consuming and affects the presentation of other normal weaving textures. Furthermore, some existing processes result in loose threads remaining within the radial elongated holes. This application provides a knitted fabric in which radial elongated holes are formed by misaligning two adjacent but not completely adjacent fabric regions, resulting in smooth hole edges. The loose threads caused by the misalignment can be hidden on the back of the fabric region, making the holes clean, transparent, and unobstructed.

[0020] The following description, with reference to the accompanying drawings, illustrates some preferred embodiments of the present application. It should be noted that the following description is for illustrative purposes only and is not intended to limit the scope of protection of the present application. The flowcharts used are for illustrating the operations performed by the system according to embodiments of the present application. It should be understood that the described operations are not necessarily performed precisely in sequence. Instead, various steps may be processed in reverse order or simultaneously. Furthermore, other operations may be added to these processes, or one or more steps may be removed from these processes.

[0021] refer to Figure 1 The exemplary schematic diagram shown is of a radially elongated hole according to some embodiments of this application, such as... Figure 1 As shown, the radial elongated hole H can be formed by the first fabric region F and the second fabric region S, which are adjacent but not completely adjacent at the edges, after being misaligned, and is surrounded by the first fabric region F and the second fabric region S. Figure 1 As shown in (a), the first fabric region F and the second fabric region S are adjacent at the dashed circle A. Referring to the attached drawing, the upper portion of the right edge of the first fabric region F is adjacent to the lower portion of the left edge of the second fabric region S. After weaving, according to... Figure 1 The arrow in (a) indicates that the second fabric region S is moved downwards in a misaligned direction. When the lower edge of the second fabric region S is aligned with the lower edge of the first fabric region F (i.e., in the same row), a [structure / structure] is formed. Figure 1 (b) shows a radially elongated hole H surrounded by a first fabric region F and a second fabric region S. The adjacent boundary (or intersection line of the two fabric regions) represented by the dashed area A forms a float L due to misalignment and stretching. In this application, the float L can be concealed on the back edge of the first fabric region F and / or the second fabric region S by performing loop weaving (e.g., bottom weaving) or tuck weaving (e.g., bottom hanging weaving) on ​​the corresponding weave. For example, the float is concealed at the bottom of the lower edge of the second fabric region S. Thus, there will be no float obstructing the formed radially elongated hole H. Concealing the float can refer to embedding the float L into the edge structural layer of the fabric, i.e., within the bottom fabric of the lower edge of the second fabric region S, through loop weaving or tuck weaving.

[0022] In some embodiments, the heights of the first fabric region F and the second fabric region S can be the same. For example, during the knitting process of a knitted fabric, the number of rows in the first fabric region F and the second fabric region S is the same. Therefore, the length (or height) of the formed radially elongated hole H can be determined by the number of rows in the first fabric region F and the second fabric region S. During the knitting process of the fabric, the length of the radially elongated hole H can be adjusted by changing the number of rows in the two fabric regions, thereby enabling the formation of holes with different radial dimensions.

[0023] The first fabric region F and the second fabric region S can be independently used as single-layer or multi-layer fabrics. When the first fabric region F and / or the second fabric region S are single-layer fabrics, the side edges of the radially elongated hole H formed by the first fabric region F and / or the second fabric region S (the right edge of the first fabric region F and the left edge of the second fabric region S in Figure 1) will be rolled inward, making the edge of the hole smooth and less prone to unraveling. The inward rolling of the single-layer fabric can be achieved by coil winding, hot pressing, or bonding. For example, a coil winding process, such as coiling, allows the coil around the hole to naturally roll inward, and then the rolled edge shape is fixed by low-temperature heat setting. After the inversion, the edge of the radially elongated hole H will naturally curl, which to some extent expands the width of the radially elongated hole H, prevents unraveling, and fixes the hole shape to keep the hole regular and less prone to deformation due to external forces.

[0024] When the first fabric region F and / or the second fabric region S are multi-layered fabrics, the number of weave rows in the portion of the radial elongated hole H formed by the first fabric region F and / or the second fabric region S belonging to the single-layer main fabric can be adjusted to adjust the width of the radial elongated hole H. Thus, the width of the radial elongated hole H can also be adjusted during the knitting process of the knitted fabric, thereby enabling the formation of holes of different widths. The single-layer main fabric is a key component determining the core properties of the fabric. For example, the first fabric region F and / or the second fabric region S can be a double-layered fabric, where the first layer has a higher yarn content and a more complex weave design, such as twill, while the second layer has a simple weave, such as plain weave, connected to the first layer by connecting yarns. In this case, the first layer is the single-layer main fabric and can be used alone. For example, the radial elongated hole H is formed by staggered stretching. The second layer, being an auxiliary layer, has low strength and therefore cannot be used as a single-layer main fabric.

[0025] In some embodiments, the width of the radially elongated hole H can be widened by shift-loop weaving. For example, in the area corresponding to the adjacent boundary (i.e. Figure 1 The needle positions (in the dashed circle A) are knitted by shifting the loops to the left and right respectively, thereby enabling the expansion of the radial elongated hole H based on the number of shifted needles.

[0026] The radial elongated hole H can be either fully transparent or semi-transparent. For example, the radial elongated hole H can be made fully transparent by using the aforementioned method of hiding the float yarn. When the knitted fabric is a multi-layered fabric, such as a double-layered fabric, the first fabric region F and the second fabric region S can be formed as a single-layered fabric (or called the surface layer fabric), while the bottom layer fabric can be formed in standard loops or loosely woven. After forming the radial elongated hole H, the bottom layer fabric can form a semi-transparent effect with slight gaps, thus making the radial elongated hole H a semi-transparent hole.

[0027] When weaving the first fabric region F and the second fabric region S used to form the radial elongated holes H, partial weaving or multi-yarn-pigment weaving can be used. Partial weaving can be performed in selected areas to form, such as... Figure 1 (a) shows a first fabric region F and a second fabric region S with only partial edges adjacent to each other. Multi-yarn-head side-weaving can weave the sides of the two fabric regions simultaneously, completing the side-weaving process synchronously and maintaining the consistency of the sides of the two fabric regions.

[0028] refer to Figure 2 Exemplary renderings of knitted fabrics according to some embodiments of this application are shown. Figure 2 As shown, multiple radial elongated holes can be formed on the knitted fabric, and they can be arranged in parallel. (See the following reference.) Figure 3 The illustrated exemplary knitting process diagrams of knitted fabrics according to some embodiments of this application are used to form such... Figure 2 The knitted fabric shown. (As shown) Figure 3 As shown, the knitted fabric is woven using yarns A and B, both of which are double-wrapped polyester high-elastic spandex yarns. The arrows indicate the direction the knitting machine is facing. The specific knitting process includes: The first row is woven with yarn A as the face; The second row is woven with B yarn as the base, and some rows are woven with loops and hanging loops as the base (in rows 1, 3, 5, 9, 11, 15, 17, 21 and 23), connecting the surface layer; The third row is a needle-flipping action that moves the stitches from the back needle bed to the front needle bed in the corresponding stitches (stitches 12, 13, 18, and 19). The 4th row is woven with yarn A as the face yarn and the 7th row is woven with yarn A as the base yarn; Row 5 is woven with B yarn as the base, and some rows (rows 4, 6, and 10) are woven with a bottom loop and a top loop stitch to connect the surface layer. Row 7 is woven with a bottom tight loop stitch, and rows 1 and 12 are woven with a top loop stitch. The sixth row is woven with yarn A as the face; Row 7 is woven with B yarn as the base, and some rows (rows 9 and 11) are woven with loop stitches to connect the surface layer. The surface layer is woven in row 7 and with loop stitches in row 12. Row 8 is woven with yarn A as the face; Row 9 is woven with B yarn as the base, and part of the weave (row 10) is woven with loop stitches to connect the surface layer. Loop stitches are also woven in rows 7 and 12. The 10th row is woven with yarn A as the face; Row 11 is woven with B yarn as the base, and some rows (rows 9 and 11) are woven with loop stitches to connect the surface layer. Loop stitches are also woven in rows 7 and 12. Rows 12 to 21 are repeats of rows 4 to 11; Row 22 is woven with yarn A as the face; Row 23 is a combination of base knitting with B yarn and interlaced knitting with looped knitting on the bottom and hanging stitch knitting on the top, connecting the top layer.

[0029] Columns 7 to 12 and 13 to 18 are plain weave areas between the warp perforations; columns 12 and 13 of columns 6 to 13 and columns 18 and 19 of columns 14 to 21 represent the height of the warp perforations. The junction of the two weave areas is stretched to form floats after the warp perforations are formed. The floats can be hidden by underlay weaving and underlay weaving in column 13.

[0030] refer to Figure 4 The illustrated diagram for the above-described weaving process shows a stepped first fabric region F and a second fabric region S. In the 12th and 13th weave rows, the 7th to 12th weave rows form the upper left edge HU of the radially elongated hole, and the 13th to 18th weave rows form the lower right edge HD of the radially elongated hole. When the first fabric region F and the second fabric region S are misaligned, that is, when the second fabric region S moves downwards, the lower right edge HD of the hole will move downwards and become flush with the lower edge of the first fabric region F. The 12th weave row from the 4th to the 13th weave rows forms the left side L of the radially elongated hole, and the 12th to 13th weave rows form the right side HR of the radially elongated hole. The 12th and 13th weaves from the 6th to the 13th weaves, and the 18th and 19th weaves from the 14th to the 21st weaves, are the hole height G for radial punching.

[0031] The radially elongated holes in the knitted fabric provided in this application have smooth edges, are not easily unraveled, and possess extremely strong stability. Furthermore, they are less restricted in terms of appearance, and the hole size can be adjusted according to different practical needs. Unlike traditional small holes, the radial holes in this application have a strong visual impact, providing a powerful visual stimulus.

[0032] In addition, the radial holes in this application do not have floating lines; the floating lines are hidden on one side of the hole edge, making the holes clean and transparent without obstruction.

[0033] Furthermore, the radial holes of this application have strong variability and control over their appearance, and the final holes are more diverse in number and arrangement in terms of area compared to traditional mesh weaving, and are less restricted by it.

[0034] This application also provides a method for manufacturing the knitted fabric as described above. For content identical or similar to the foregoing sections, please refer to the above description, which will not be repeated here. References Figure 5 The manufacturing method may include: Step S1: Weave the first fabric region and the second fabric region in a stepped pattern; the first fabric region and the second fabric region are adjacent but their edges are not completely adjacent.

[0035] Step S2: Misalign the first fabric region and the second fabric region to form the radial elongated hole, and perform loop weaving or tuft weaving on the adjacent boundaries of the first fabric region and the second fabric region based on the floating thread formed by the misalignment, hiding the thread on the back edge of the first fabric region and / or the second fabric region.

[0036] The aforementioned stepped knitting can be achieved by selecting needles on the needle bed and moving the needle bed laterally, knitting the fabric at different needle positions in different rows, thereby forming a continuous, regular, stepped hierarchical structure with equal height differences. This can be combined with... Figure 3 The knitting process diagram is used to illustrate that the first fabric area can be knitted first in the 7th to 12th knit rows of the low knitting row, and then the second fabric area can be knitted in the 13th to 18th knit rows of the high knitting row by selecting needles, thus presenting a stepped shape in the horizontal direction.

[0037] In some embodiments, the method for manufacturing knitted fabrics provided in this application can be implemented using a computerized horizontal knitting machine. Therefore, the knitted fabric is integrally formed and woven, exhibiting high consistency and achieving excellent perforation.

[0038] In some embodiments, the radial holes of the knitted fabric can be formed by partial knitting or multi-yarn-head side-by-side knitting. Multi-yarn-head side-by-side knitting refers to the simultaneous knitting of multiple areas by two or more independent yarn heads, each responsible for the left and right sides (or different areas) of the fabric. In this application, multi-yarn-head side-by-side knitting can simultaneously form the first knitting area and the second knitting area, thereby improving knitting efficiency. (The advantages of multi-yarn-head side-by-side or separate knitting include that when only one yarn head is used for knitting, after knitting...) Figure 1 (a) After F section, the yarn feeder needs to start weaving again from the bottom of S section. At this time, a floating line will appear from the top of F section to the bottom of S section. However, when two yarn feeders are weaving at the same time, one yarn feeder is responsible for weaving F section from bottom to top, and the other yarn feeder is weaving from the bottom of S section from top to top. The above floating line will not appear.

[0039] In some embodiments, in addition to the radial holes, the knitted fabric may also have other hole shapes or textures. Other hole shapes may include round holes, square holes, diamond holes, or various irregularly shaped holes. Textures may include plain weave, rib weave, twill weave, satin weave, lace weave, twisted weave, jacquard weave, etc., and can be formed by adjusting the specific knitting process.

[0040] This application also provides a knitted product prepared using the knitted fabric described above. For details identical or similar to those described above, please refer to the preceding description; further details will not be repeated here. The knitted product may include at least a knitted shoe upper. The radial perforations can be adjusted according to the specific knitting process, thereby forming them at any location on the knitted shoe upper.
