[0002] The traditional flying woven upper adopts a single-direction weaving structure. Although it has certain elasticity and breathability, its strength, breathability and aesthetics still need to be improved.

[0003] In knitted uppers, due to the characteristics of flying weaving, intarsia is usually required when making hollow holes, and the size of the squares is also limited. During the knitting process, a large area of ​​weft yarn is used to form a loop to support the hollow square area, and the weft yarn that passes through the hollow holes will leave weft floating lines, affecting the overall effect of the hollow holes. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an interwoven hollow through-hole weaving method and an interwoven hollow fabric, wherein the hollow through-holes of the interwoven weaving do not have a large number of floating weft yarns inside and are completely hollow, and the size of the hollow through-holes is controllable; and the weaving efficiency is higher.

The method for interweaving hollow through-hole weaving comprises the following specific steps: S1: The machine head controls the yarn mouth A to do surface weaving on the alternate needle positions through the warp yarn in the first weaving row to form a warp yarn loop; S2: The second weaving row is to press the warp yarn loops of the first weaving row to help the warp yarns form loops; S3: Repeat the weaving action of step S1 and step S2 for a number of weaving rows, so that the warp yarn forms a warp chain in the warp direction; S4: After completing step S3, the machine head controls the weft yarn of the yarn mouth B to perform face-separated needle weaving, and the weft yarn forms a weft yarn loop in the weft direction, and there are a number of empty needles between two adjacent face-separated weft yarn loops, and the weft yarn loops and the warp yarn loops are connected in a loop at the overlapping needle positions to connect the warp yarn and the weft yarn, and the two adjacent weft yarn loops and the warp chain form a hollow through hole.

[0006] Furthermore, the warp yarn and the weft yarn are both made of materials with a melt-bonding effect, such as TPU coated yarn, silicone coated yarn, etc., which have a shaping effect.

[0007] Furthermore, the warp yarn is woven with at least one thermoplastic yarn, and the thermoplastic yarn plays a shaping and supporting role.

[0008] Second aspect An interwoven hollow fabric is provided. The hollow holes formed by weaving using the above interwoven hollow through-hole weaving method are used as circulation units. The above weaving steps are repeated to weave the interwoven hollow fabric. The interwoven hollow fabric is composed of at least one layer of fabric surface.

[0009] The advantages of the present invention are: 1. The present invention forms hollow holes by interweaving warp yarn coils and weft yarn coils.

[0010] 2. Because there are only two weft threads, upper and lower, in each unit hollow hole, and the weft threads are not woven in a continuous string, there are no large number of floating weft threads inside the hollow hole formed by interweaving, and it is completely hollow.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1 like Figures 1 to 4 As shown, Figure 1 In the weaving schematic diagram shown, each interwoven hollow through-hole warp chain is a warp yarn coil 11, and there are three empty needles between two adjacent weft yarn coils 21. Figure 3 In the weaving schematic diagram shown, each interwoven hollow through hole 3 has three warp yarn loops 11 in the warp direction, and three empty needles are spaced between two adjacent weft yarn loops 21.

[0028] The present invention provides an interwoven hollow through-hole weaving method, which provides a flat knitting machine, on which warp yarn 1 and weft yarn 2 are woven, and the warp yarn and weft yarn are both made of materials with a melt-bonding effect, such as TPU coated yarn, silicone coated yarn, etc., which have a shaping effect (the bonding performance can be activated by heating, melted and produce viscosity, the fabric structure is fixed by the bonding point, the fiber slippage is inhibited, and the local area stiffness, deformation resistance and dimensional stability are improved), the shaping temperature is 120°C-220°C, and the warp yarn uses at least one thermoplastic yarn to participate in the weaving, and the thermoplastic yarn plays a shaping support role. The flat knitting machine has a head, and the head controls at least two yarn mouths A and B, the yarn mouth A performs warp weaving, and the yarn mouth B performs weft weaving, and the interwoven hollow through-hole weaving method includes the following specific steps: S1: the machine head controls the yarn mouth A to perform surface weaving on the alternate needle positions through the warp yarn 1 in the first weaving row to form the warp yarn loop 11; S2: The second weaving row is to press the warp yarn loops 11 of the first weaving row to assist the warp yarns in forming loops; S3: Repeat the weaving actions of step S1 and step S2 for a number of weaving rows, so that the warp yarn 1 forms a warp chain in the warp direction; S4: After completing step S3, the machine head controls the weft yarn of the yarn mouth B to perform face-separated needle weaving, and the weft yarn 2 forms a weft yarn coil 21 in the weft direction, and a number of empty needles are spaced between the two adjacent weft yarn coils 21. Preferably, there are 3 empty needles between the two adjacent weft yarn coils. The weft yarn coil 21 is connected with the warp yarn coil 11 at the overlapping needle position to connect the warp yarn and the weft yarn, and the two adjacent weft yarn coils 21 and the warp chain form a hollow through hole 3.

[0029] The present invention is an interwoven hollow perforated process, which refers to a hollow knitted structure formed by interweaving warp yarn 1 and weft yarn 2. The warp support of the interwoven hollow process is provided by the warp chain woven by the warp yarn, and the weft support is provided by the weft coil. Using the warp and weft interweaving technology, the coils woven by the weft yarn and the warp chains woven by the warp yarn form a unique hollow perforated structure, which enhances the air permeability and aesthetics of the upper. According to the needs, the size of the hollow perforated area can be adjusted by adjusting the length of the warp chain and the number of empty needles woven by the weft yarn. The present invention uses thermoplastic fibers and coated yarns for weaving, which can improve the problem of insufficient physical properties of interwoven hollow fabrics, enhance the wear resistance, folding resistance, support, and deformation resistance of the interwoven hollow fabric, so that the hollow fabric can be used as a part of the upper without the need for other materials.

[0030] The machine head is a knitting device. The yarn mouth mentioned above can also be changed into a yarn guiding device, including a yarn seat and a yarn mouth (similar to the yarn output / yarn guiding parts).

[0031] The advantages of the present invention are: 1. The present invention forms hollow holes by interweaving warp yarn coils and weft yarn coils.

[0032] 2. Because there is only one weft in each unit, and the wefts are not woven in a continuous string, there are no large number of floating weft yarns inside the hollow holes formed by interweaving, and the holes are completely hollow.

[0033] 3. The hollow weft and warp yarns of the interwoven weaving do not use local weaving technology (the local weaving process requires increasing the number of weaving rows of the fabric, the local weaving time is long, and the weaving efficiency is low), or frequently avoid the yarn mouth, which reduces the weaving time.

[0034] 4. The warp support of the interwoven hollowing process is provided by the warp chain of the warp yarn, and the weft support is provided by the weft yarn coil. There is no need for the weft yarn to form a large area of ​​loops as the fabric basis, and the weft efficiency is higher. The traditional openwork structure requires at least 2 groups of weft yarns and 2 groups of warp yarns to interweave to form a basic grid. The size of this type of grid is limited by the lack of effective restraint of the weft yarn in the middle, which is prone to floating lines.

[0035] 5. The size of the hollow holes of the interwoven weaving can be freely adjusted according to the needs by adjusting the density or quantity of the warp yarn coils (such as increasing the number of warp yarn coils).

[0036] Embodiment 2 like Figure 5 As shown, an interwoven hollow fabric, the hollow holes formed by weaving the above-mentioned interwoven hollow hole weaving method are used as a circulation unit, and the above-mentioned weaving steps are repeated to weave an interwoven hollow fabric, and the interwoven hollow fabric is composed of at least one layer of fabric surface. The interwoven hollow fabric is composed of at least one layer of fabric surface, and can also be composed of a single-layer fabric surface and a multi-layer fabric surface. The interwoven hollow fabric can be used as a part of the upper, which can enhance the air permeability and aesthetics of the upper.

[0037] The above-mentioned cycle unit is interpreted as the smallest unit of a knitting machine to complete a complete action during the weaving process. These steps are repeated periodically to form the overall structure of the fabric. The number of repetitions of the cycle unit depends on the length, density and pattern complexity requirements of the fabric.

[0038] Reference Figure 6-9 , warp knitting is performed by weaving warp loops through a movable yarn guide device on a flat knitting machine, and a yarn seat yarn guide device of a movable yarn mouth 40 is used (the yarn seat 10 structure of the movable yarn mouth 40, the yarn seat 10: is equipped with an adjustment mechanism (controlling the overall displacement of the yarn seat and controlling the independent displacement of the movable yarn mouth), and the yarn mouth is quickly adjusted from the initial position to the weaving position through coordinated control.

[0039] The movable yarn mouth 40 supports multi-directional displacement (up and down, left and right, front and back) and swing functions (through a third adjustment mechanism), is rotatable and arranged in layers, and allows flexible movement within the active area of ​​the yarn holder 10.

[0040] Layered design: The movable yarn feeders are arranged in different layers, and the fixed yarn feeders and the movable yarn feeders are installed in staggered layers to avoid interference and expand the weaving range.

[0041] Adjustment of yarn outlet: The movable yarn mouth 40 is provided with an independent adjustable yarn outlet 60, which can be adjusted in spacing, height and size to meet different yarn requirements). The movable yarn mouth 40 is provided with a plurality of independent yarn outlets 60, the spacing between adjacent yarn outlets 60 is adjustable, the height of the independent yarn outlets 60 is independently adjustable, and the size of the independent yarn outlets 60 is adjustable. At least one optimized structure constituting the yarn mouth can be arbitrarily selected from adjustable spacing, adjustable height, and adjustable size of the yarn outlet. The yarn outlet structure and the structure for adjusting the yarn outlet can be set on either a fixed yarn mouth or a movable yarn mouth.

[0042] The above-mentioned weaving device is only an example, and any device or equipment capable of achieving the same function is within the scope of the present invention.

[0043] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
