Description

Technical Field

[0001] This application relates to the field of textile technology, specifically to a method for weaving lightweight weft-knitted fabrics. Background Technology

[0002] Double-sided weft-knitted fabrics are a widely used type of fabric, typically including rib knit and double-sided jacquard knits. These fabrics possess good elasticity and structural stability due to the interlaced yarn structure, making them commonly used in the production of various textile products and footwear components. However, because double-sided weft-knitted fabrics are woven from interlaced yarns on both sides, they require a large amount of yarn, resulting in a higher overall fabric density and weight. Furthermore, the dense fabric structure leads to a lack of breathability channels, making it difficult to meet the current core design requirements of lightweight and high breathability. Especially in the footwear industry, as market demands for shoe comfort and lightweight construction become increasingly stringent, higher technical standards are being set for weight control and breathability of footwear fabrics. Simultaneously, fabrics are required to possess good structural strength, resilience, and aesthetic design. The structural defects of traditional double-sided weft-knitted fabrics prevent them from meeting the practical application needs of the footwear industry.

[0003] In existing technologies, although attempts have been made to reduce fabric weight and optimize breathability by weaving with fine-gauge yarns, the lack of precise process parameter control schemes makes it difficult to stably control the size of the yarns formed by weaving at ultra-fine specifications, and problems such as loose yarn arrangement and flying yarn are prone to occur. Summary of the Invention

[0004] In view of the above problems, this application provides a weaving method for lightweight weft-knitted fabrics, which solves the problem that existing double-sided weft-knitted fabrics are difficult to adapt to the core design requirements of current products for lightweight and high breathability.

[0005] To achieve the above objectives, the inventors provide a method for knitting a lightweight weft-knitted fabric, which employs a double needle bed to knit the weft-knitted fabric; the method includes the following steps:

[0006] Preset pattern;

[0007] One needle bed is used to knit with the first yarn; the other needle bed is used to knit with the second yarn to form loops in the pattern area. By turning the needle, all the loops of the second yarn are correspondingly placed on the corresponding loops knitted by the first yarn to form the pattern.

[0008] Furthermore, the weft-knitted fabric includes jacquard units, and the weaving of the jacquard units includes the following steps:

[0009] Pre-set jacquard patterns;

[0010] One needle bed uses a first yarn to weave the base fabric; the other needle bed uses a second yarn to weave loops in the jacquard pattern area. By turning the needle, all the loops of the second yarn are looped onto the loops of the base fabric to form a jacquard pattern on the base fabric.

[0011] Furthermore, the weft-knitted fabric includes mesh units, and the weaving of the mesh units includes the following steps:

[0012] Preset mesh pattern;

[0013] One needle bed uses a first yarn to weave the base fabric in the patterned area of ​​the mesh; another needle bed uses a second yarn to weave loops in the patterned area of ​​the mesh. By turning the needle, all the loops of the second yarn are looped onto the corresponding loops of the base fabric woven by the first yarn, forming the edge of the mesh. At the same time, at the corresponding positions of the mesh in the patterned area of ​​the mesh, neither the first yarn nor the second yarn performs loop weaving, so as to form the mesh of the fabric.

[0014] Furthermore, the first yarn is formed using full-position knitting.

[0015] Furthermore, the first yarn is a transparent yarn.

[0016] Furthermore, the first yarn is a low-elasticity or non-elasticity yarn with a density of 150D-900D.

[0017] Furthermore, the second yarn is formed by alternating full-position weaving.

[0018] Furthermore, the second yarn is a 75D-300D high-elastic yarn or a 140D-280D covered yarn.

[0019] Furthermore, the double needle bed mesh parameters are set to 7-8 mesh segments and mesh values ​​of 230-270, and the diameter of the second yarn on the pattern is 0.1mm-0.3mm.

[0020] Furthermore, before knitting the weft-knitted fabric, a starting point is knitted. The starting point is made by knitting yarn in the front and back needle beds in a one-to-one pattern. After the weft-knitted fabric is completed, the starting point is removed, and then the weft-knitted fabric is shaped according to the preset temperature of the second yarn material.

[0021] Unlike existing technologies, the above technical solution achieves clear pattern formation while ensuring that the fabric has a single-layer structure, effectively reducing the amount of yarn used and significantly reducing the weight of the fabric to meet the requirements of lightweighting.

[0047] A method for knitting a lightweight weft-knitted fabric involves using a double-needle-bed flat knitting machine. One needle bed (front or back) is knitted with a first yarn 101, while the other needle bed (back or front) is knitted only in the pattern 20 area using a second yarn 201 to form loops. Through a turning needle process, all loops woven with the second yarn 201 are overlaid on the corresponding loops woven with the first yarn 101, causing the loops of the second yarn 201 and the first yarn 101 to overlap in the pattern 20 area, ultimately resulting in a single-layer weft-knitted fabric with pattern 20. This method achieves clear formation of pattern 20 while ensuring that the fabric as a whole is a single-layer structure, effectively reducing the amount of yarn used and significantly reducing the fabric weight to meet lightweight requirements.

[0048] The following combination Figures 1-6 An embodiment of a knitting method for a lightweight weft-knitted fabric is provided, which employs a double needle bed to knit the weft-knitted fabric; the method includes the following steps:

[0049] Preset pattern 20;

[0050] One needle bed is knitted using the first yarn 101; the other needle bed is knitted using the second yarn 201 to form loops in the area of ​​the pattern 20. By turning the needle, all the loops of the second yarn 201 are correspondingly placed on the loops of the first yarn 101 to form the pattern 20.

[0051] The above-mentioned pattern 20 can be flexibly set according to the appearance design and functional requirements of the fabric application scenario. It can be a regular geometric pattern such as stripe, grid, diamond, wave, etc., or a personalized custom pattern such as letters, numbers, brand logos, cartoon patterns, abstract textures, etc. It can also be a partial texture pattern, gradient pattern, etc. One or more of the above-mentioned patterns 20 can be preset by adjusting the size and the position of the arrangement.

[0052] See Figures 5-6 As shown, the aforementioned needle flipping refers to the process of transferring a loop held by a needle on one needle bed (front or back) to the corresponding needle on another needle bed during double-needle-bed knitting. This action only changes the needle bed affiliation of the existing loop and does not involve feeding new yarn or knitting new loops.

[0053] The other needle bed described above uses the second yarn 201 to knit loops in the pattern 20 area. This means that the second yarn 201 is only used to knit loops in the pattern 20 area, and not in the non-pattern 20 area. Specifically, at the boundary of the non-pattern 20 area, the second yarn 201 is hung on the back of one needle bed by means of a needle flipping action. Although the other needle bed continues to perform loop forming in the non-pattern 20 area, there is no feeding of the second yarn 201 throughout the process. This ensures that the second yarn 201 only participates in the knitting and forming of the fabric in the preset pattern 20 area. There are no excess loops, floats, or exposed yarns formed by the second yarn 201 in the non-pattern 20 area, ensuring that the fabric is a single-layer structure, effectively reducing the amount of yarn used, and significantly reducing the weight of the fabric to meet the requirements of lightweighting.

[0054] The knitting range of the pattern 20 area covers at least one entire row (each row contains at least one weave). In conventional applications, it often involves multiple consecutive rows, such as diamond or checkered patterns, which require multiple rows to be knitted together. In some embodiments, when another needle bed uses the second yarn 201 to knit the pattern 20 area, for each row of the pattern 20 area, the needle bed first completes the knitting of all or part of the loops within that row. After the loop is formed, a turn is performed, placing the loop onto the loop of the corresponding row of the first yarn 101. This process is repeated to complete the knitting of multiple rows, ultimately forming a clear and complete pattern 20 in the pattern 20 area. The turn-over action for each row can be flexibly implemented according to requirements. It can either complete the turn-over of all loops within the row at once, or it can be done gradually, such as turning over in batches at preset intervals of a number of loops, or performing the turn-over action sequentially on several consecutive loops.

[0055] Based on the lightweight weft knitting method described in this application, one or more jacquard, mesh, or combined jacquard and mesh single-layer weft knitting fabrics can be flexibly knitted to meet the diverse needs of fabric appearance design and structural function in various fields.

[0056] See Figure 1 and Figure 2 As shown, in some embodiments, the weft-knitted fabric includes jacquard units, and the knitting of the jacquard units includes the following steps:

[0057] Preset jacquard pattern 20;

[0058] One needle bed uses the first yarn 101 to weave the base fabric 10; the other needle bed uses the second yarn 201 to weave loops in the jacquard pattern 20 area. By turning the needle, all the loops of the second yarn 201 are looped on the corresponding loops of the base fabric 10 to form the jacquard pattern 20 on the base fabric 10.

[0059] See Figures 3-4 As shown, in some embodiments, the weft-knitted fabric includes mesh units, and the weaving of the mesh units includes the following steps:

[0060] Preset mesh pattern 20;

[0061] One needle bed uses a first yarn 101 to weave the base fabric 10 in the area of ​​the mesh pattern 20; another needle bed uses a second yarn 201 to weave loops in the area of ​​the mesh pattern 20. By turning the needle, all the loops of the second yarn 201 are looped onto the corresponding loops of the base fabric 10 woven by the first yarn 101, forming the edge of the mesh. At the same time, at the corresponding position of the mesh in the area of ​​the mesh pattern 20, neither the first yarn 101 nor the second yarn 201 performs loop weaving action, so as to form the mesh of the fabric.

[0062] The weaving structure of the base fabric 10 can be flexibly selected according to actual needs without fixed restrictions; preferably, the first yarn 101 adopts a full-position weaving process to form the main structure of the base fabric 10. The full-position woven base fabric 10 is more sparse overall, while still maintaining stable structural strength and good dimensional stability. It can effectively reduce the fabric surface density to achieve lightweighting, and can also form uniform air-permeable channels, taking into account both the overall lightweighting and air permeability requirements of the fabric.

[0063] In some embodiments, the first yarn 101 is a transparent yarn. As the main yarn of the base fabric 10, the transparent yarn can weaken the visual presence of the base fabric 10 itself, avoid visual interference with the pattern 20 formed by the second yarn 201, and allow the color, texture and mesh transparency of the preset pattern 20 to be clearly presented, thereby enhancing the overall appearance and sophistication of the fabric. At the same time, the transparent yarn helps to enhance the transparent visual effect of the fabric, especially when combined with the sparse all-weave structure, thereby improving breathability and lightweighting from both physical structure and visual performance dimensions. The transparent yarn can be any transparent or semi-transparent MONO (monofilament) yarn conventionally used in weft knitting processes in the art. The MONO yarn includes, but is not limited to, PET monofilament (Polyethylene Terephthalate), TPU monofilament (Thermoplastic Polyurethane), TPEE monofilament (Thermoplastic Polyester Elastomer), PP monofilament (Polypropylene), and PA monofilament (Polyamide).

[0064] The knitting structure of pattern 20 in this application can be flexibly selected according to actual needs and is not fixed. Preferably, the second yarn 201 is formed by one-alternate-one-full-position knitting. The needle bed where the second yarn 201 is located selects needles to perform hooking and looping actions according to the interval needle position rule of "one needle participating and one needle being empty". The two loop rows of the current needle bed are combined longitudinally to form a complete knitting row. Unlike the full-position knitting method in which a single loop row independently forms a complete knitting row, this one-alternate-one-full-position knitting process uses the complementary support of the interval needle positions of two loop rows to form a tighter structure between adjacent loops, strengthens the bonding force between loops, significantly improves the structural strength and morphological regularity of pattern 20, and effectively suppresses problems such as loop displacement, loose edges, and contour deformation that occur during knitting and subsequent use, ensuring the stability and durability of fabric pattern 20.

[0065] The selection of materials for the first yarn 101 and the second yarn 201 is not strictly limited. They can be flexibly selected based on the actual needs of the fabric, appearance design requirements, and the adaptability of the weaving process. The two yarns can be made of the same material or different materials can be selected according to the functional zoning requirements. The naming of "first yarn 101" and "second yarn 201" is used to distinguish the yarns that support the weaving of the base fabric 10 from the yarns that support the weaving of the jacquard pattern 20, the mesh edge, and other pattern structures 20. This is to clearly define the functional division and technological role of different yarns in the double needle bed collaborative weaving process, rather than to impose exclusive restrictions on the yarn materials themselves.

[0066] In some embodiments, the first yarn 101 is a low-elasticity or non-elasticity yarn of 150D-900D. The low-elasticity or non-elasticity characteristics can effectively control the overall tensile deformation of the fabric, improve the dimensional stability of the base fabric 10, and avoid shrinkage of the base fabric 10, offset or deformation of the pattern 20 during weaving, stitch turning and subsequent use; the linear density range of 150D-900D takes into account both the structural strength and lightweight requirements of the base fabric 10, ensuring that the base fabric 10 has sufficient tensile and abrasion resistance to meet the long-term stress requirements of the fabric application scenario, while avoiding the fabric from being too thick and stiff, providing a flat and firm support interface for the weaving of the upper pattern 20.

[0067] In some embodiments, the second yarn 201 is a 75D-300D high-elastic yarn or a 140D-280D covered yarn. The 75D-300D high-elastic yarn or 140D-280D covered yarn can adaptively adjust during stitching and fabric bending, reducing the risk of loop breakage and slippage. It also improves the fatigue resistance of the pattern 20 area and the mesh edges, making it less prone to loosening and collapse over long-term use. Furthermore, this fineness range ensures a delicate loop structure and a clear outline of the pattern 20, avoiding rough texture and bulky edges caused by excessively thick yarn. The second yarn 201 can be made of chemical fiber, staple fiber, chenille, etc. The covered yarn refers to a yarn with spandex elastic yarn as the core layer and a non-elastic yarn wrapped around the surface; it can be a single-covered yarn (wrapped with one layer of non-elastic yarn), a double-covered yarn (including two layers of non-elastic yarn, where the two layers of non-elastic yarn are twisted in opposite directions), etc.

[0068] The mesh size parameter directly determines the loop tension and forming tightness when the needle hooks the yarn. Setting the mesh size parameter of the double needle bed to 7-8 mesh size and 230-270 mesh size can provide moderate and stable knitting tension for the polyester yarn. This avoids the loop loosening and yarn detachment from the needle hook due to insufficient tension, while also preventing excessive tension from causing excessive yarn stretching and increasing the risk of breakage. Preferably, the diameter of the second yarn 201 on the pattern 20 is 0.1mm-0.3mm, so that the polyester yarn can closely follow the movement trajectory of the needle during the knitting process, reducing the excess displacement and slack allowance of the yarn in processes such as needle position switching and needle flipping. With the combined effect of the two, the polyester yarn loops are formed regularly and interlocked tightly, and the yarn is always constrained within the preset weaving path. This effectively avoids the yarn free-flowing phenomenon caused by tension imbalance and poor matching between yarn diameter and needle position in traditional processes. Ultimately, it achieves a clean effect without flying yarn between polyester design lines, which not only improves the visual regularity and aesthetics of the fabric surface, but also eliminates the foreign body feeling caused by flying yarn, significantly optimizing the comfort of the fabric.

[0069] Before knitting the weft-knitted fabric, a starting point is knitted. This starting point involves knitting the yarn in alternating stitches on both the front and back needle beds. After the weft-knitted fabric is completed, the starting point is removed. Depending on the characteristics of the yarn, the removed edges may exhibit varying degrees of curling. The weft-knitted fabric needs to be shaped according to the preset temperature of the second yarn 201 material. This shaping can be achieved through hot pressing or air pressing as needed. In some embodiments, air pressing is used to shape the weft-knitted fabric; the air pressing temperature varies depending on the material of the second yarn 201: short fibers: 80-140℃; synthetic fibers: 120-190℃. In some embodiments, hot pressing is used to shape the weft-knitted fabric; the fabric edge is hung on a nail board with a layer of silicone padding on top to prevent the edge nails from damaging the machine during hot pressing. Hot pressing involves an upper and lower die. The hot pressing temperature is adjusted depending on the yarn, with the overall actual temperature controlled between 120-190℃. The hot pressing and cold pressing times are approximately 50-65 seconds.

[0070] The following example uses a double-needle bed flat knitting machine to knit the aforementioned lightweight weft-knitted fabric. (See attached image.) Figure 7 As shown, a flat knitting machine has one knitting head and three control systems. The knitting head controls at least two yarn feeders, both of which perform weft knitting.

[0071] First Yarn 101: 900D TPU transparent monofilament;

[0072] Second yarn 201: Spandex is 40D, polyester is 75D / 36F single-wrap yarn;

[0073] Back needle bed feeder: Only one feeder is configured to fix the first yarn 101;

[0074] Front needle bed feeder: Multiple feeders are configured according to the color requirements of pattern 20, and each feeder corresponds to a second yarn 201 of a certain color.

[0075] First, use scrap yarn to knit the entire position of the front and back needle beds alternately as the start-up;

[0076] Back needle bed knitting base fabric 10. Place the first yarn 101 on the back needle bed, start full-position knitting on the back needle bed, and ensure that the first yarn 101 only contacts the back needle bed through path control; use sinkers to fix the first yarn 101 to prevent it from deforming during the knitting process;

[0077] Knit a diamond pattern 20 on the front needle bed. Place the second yarn 201 on the front needle bed and start knitting on the front needle bed. Hang the yarn on the front needle bed by knitting one full position every other position to prevent it from coming off completely during the subsequent turning motion.

[0078] The loops formed by the diamond pattern 20 are transferred from the previously independently knitted front needle bed to the back needle bed through a turning motion, according to the design of pattern 20. During this transfer, the knitted structure is not looped but rather held as a gathered loop on the back needle bed. This process is repeated to form the diamond pattern 20. Specifically:

[0079] First row: The first row of diamond pattern is designed according to pattern 20. The stitches are turned over to transfer the loops of the corresponding front needle bed to the needles of the adjacent back needle bed.

[0080] Second row: The knitting action is performed on the entire back needle bed;

[0081] Third row: The second row of the diamond pattern is designed according to pattern 20, and the stitches are turned to transfer the loops of the corresponding front needle bed to the needles of the adjacent back needle bed.

[0082] Fourth row: The knitting motion is performed on the entire back needle bed;

[0083] Repeat this process until all the loops of design 20 are turned to the back needle bed;

[0084] Because the three systems of the knitting head can synchronize needle movement, the actions of the first and second rows can be performed simultaneously. Needles with turning needles perform turning needle movements on the front and back needle beds, while the remaining needles knit independently on the back needle bed.

[0085] After weaving is complete, the waste yarn is removed to create a smooth edge;

[0086] The upper mold temperature is 260℃, the lower mold temperature is 140℃, and the hot pressing and cold pressing times are 60 seconds each.

[0087] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
