Description

Technical Field

[0001] The invention relates to a knitted shoe upper with a three-dimensional effect and a manufacturing method thereof. Background Art

[0002] Knitted uppers are soft, comfortable, and breathable. To enhance the three-dimensional effect of knitted fabrics, a common practice is to create a jacquard weave, weaving a pattern into the upper to create a three-dimensional effect. This approach requires high-quality knitting equipment and is relatively complex to produce. Another approach is to affix reinforcing components to the upper for both decorative and enhanced effects. However, if these reinforcements are placed in areas where the upper is subject to repeated bending, there is a greater risk of the reinforcements falling off. In a Chinese invention patent application with application publication number CN107157017A and titled “Inlaid rope integrated upper and its weaving process”, an inlaid rope integrated upper is disclosed, comprising an upper body, with the direction of the upper body corresponding to the toes as the front and the direction corresponding to the heel as the back. The upper body comprises a toe portion, a body portion and a heel portion from front to back, a shoe opening portion being provided at the heel portion, and further comprising a reinforcing rope embedded in the upper body in a weaving manner, wherein the two ends of the reinforcing rope along the length direction are set as a first end and a second end, the first end and the second end being connected to the upper body, and the portion between the first end and the second end having an embedded section and an exposed section, the embedded section being embedded in the upper body, and the exposed section being exposed on the surface of the upper body.

[0003] The inlaid rope integrally woven shoe upper in the above-mentioned patent can strengthen the shoe upper by the inlaid rope. The inlaid rope includes an embedded section and an exposed section. The exposed section can form an integrated three-dimensional effect. However, since part of the embedded section is still hidden in the shoe upper, its three-dimensional decorative effect is difficult to show. In addition, since the exposed section is exposed on the outermost surface of the shoe upper, it is at greater risk of being scratched or pulled, especially when the exposed section is longer. This situation is more serious. If the rope body as a decorative effect is scratched, its impact on the appearance of the shoe upper will be more obvious.

[0004] In view of this, the inventors of this case conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Summary of the Invention

[0005] The present invention aims to provide a knitted shoe upper with a three-dimensional effect and better protection of the rope body. Another object of the present invention is to provide a method for manufacturing the knitted shoe upper, which has the advantages of easy manufacturing and stable structure.

[0006] In order to achieve the above object, the present invention adopts such technical solution:

[0007] A knitted shoe upper with a three-dimensional effect includes an upper body and a rope body arranged in the upper body. The upper body includes a surface layer and a bottom layer that are composited together. The rope body is arranged between the surface layer and the bottom layer. The surface layer is woven from monofilaments in a knitting manner and also includes locking yarns. The locking yarns are interwoven with the bottom layer and the surface layer and lock the rope body on the bottom layer. The diameter of the rope body is larger than the diameter of the monofilament.

[0008] As a preferred embodiment of the present invention, a plurality of mesh holes are arranged on the surface layer, and the locking yarn is a monofilament.

[0009] As a preferred embodiment of the present invention, the monofilament is a transparent monofilament or a translucent monofilament, the diameter of the monofilament is less than 0.2 mm, and the diameter of the rope body is less than 5 mm.

[0010] As a preferred embodiment of the present invention, the monofilament is polyester monofilament, nylon monofilament, polypropylene monofilament or TPU monofilament, and the bottom layer is interwoven with polyester high-elastic yarn, polyester low-elastic yarn or nylon yarn.

[0011] As a preferred embodiment of the present invention, the specification of the polyester high-elastic yarn is 75D / 36F, the specification of the polyester low-elastic yarn is 150D / 36F, and the specification of the nylon yarn is 70D.

[0012] As a preferred embodiment of the present invention, the diameter of the monofilament is 0.1 mm to 0.15 mm, and the diameter of the rope body is 0.8 mm to 1.6 mm.

[0013] As a preferred embodiment of the present invention, the rope body is a colored rope body.

[0014] As a preferred embodiment of the present invention, the surface layer includes a plurality of coil rows, the plurality of coil rows are nested together in the longitudinal direction, each coil row includes a plurality of coils arranged in the transverse direction, and the rope body extends in the transverse direction.

[0015] The present invention also proposes a method for making a knitted shoe upper with a three-dimensional effect, wherein the shoe upper is knitted using a flat knitting machine with a front needle bed and a rear needle bed, the flat knitting machine having a first yarn mouth carrying yarn A, a second yarn mouth carrying yarn B, a third yarn mouth carrying yarn C, and a fourth yarn mouth carrying yarn D. The first yarn mouth carries yarn A to knit the surface layer on the front needle bed, and the second yarn mouth carries yarn B to knit the bottom layer on the rear needle bed. Yarn A is a monofilament, and yarn C is a rope body. The diameter of the rope body is larger than the diameter of the monofilament. At the position where the rope body needs to be laid, the third yarn mouth carries yarn C to pull the floating line, and the fourth yarn mouth carries yarn D to knit in a loop on the bottom layer and gather in a loop on the surface layer and lock the rope body on the bottom layer.

[0016] As a preferred embodiment of the present invention, 52 weaving rows form a cycle unit in the upper, and the weaving method of 52 weaving rows is as follows:

[0017] The first knitting row is the surface knitting of yarn A, using spacer needles;

[0018] The second knitting row uses yarn B as the bottom layer, and is knitted using spacer needles. The knitting position is offset by one needle position compared to the first knitting row.

[0019] The third knitting row is knitted with yarn A as the surface layer, using spacer needles, and is offset by one needle position compared to the first knitting row;

[0020] The fourth knitting row is knitted with yarn B as the bottom layer, using spacer needles, and is offset by one needle position compared to the second knitting row;

[0021] The 5th and 6th knitting rows are to transfer the loops of the corresponding front needle bed needles to the needles of the rear needle bed by needle transfer;

[0022] The knitting action from row 7 to row 12 is the same as that from row 1 to row 6, but the knitting needle position is offset by 1;

[0023] The knitting action of the 13th to 18th rows is the same as that of the 1st to 6th rows;

[0024] The 19th knitting row is knitted with yarn A as the surface layer, using spacer needles;

[0025] The 20th knitting row is knitted with yarn B as the bottom layer, using spacer needles, and is offset by one needle position compared to the 19th knitting row;

[0026] The 21st knitting row is knitted with yarn A as the surface layer, using spacer needles;

[0027] The 22nd and 23rd knitting rows are the kicking actions of C yarn to adjust the yarn feeder position;

[0028] The 24th knitting row is for C yarn to do the floating line action;

[0029] The 25th knitting row is where yarn D is looped on the bottom layer and tucked on the top layer, using spacer knitting to fix yarn C on the bottom layer.

[0030] The 26th row is the bottom knitting of yarn B on the tuck needle position of the 25th row;

[0031] The knitting action of rows 27 to 47 is the same as that of rows 1 to 21, but the knitting position is offset by one needle position.

[0032] The 48th and 49th knitting rows are the kicking action of C yarn to adjust the yarn feeder position;

[0033] The 50th knitting row is for C yarn to do the floating line action;

[0034] The 51st knitting row is where yarn D is looped on the bottom layer and tucked on the top layer, using spacer knitting to fix yarn C on the bottom layer.

[0035] The 52nd knitting row is the bottom knitting made by yarn B on the tuck needle position of the 51st knitting row.

[0036] After adopting the technical solution of the present invention, the diameter of the rope body is larger than the diameter of the monofilament, which enhances the three-dimensional effect of the shoe upper. The larger the diameter of the rope body, the more obvious the three-dimensional effect. Since the monofilament is thinner, the gaps in the surface layer woven by existing knitting equipment are larger, and the rope body can be seen through the gaps, showing the decorative effect of the rope body. In addition, since the rope body is arranged between the surface layer and the bottom layer, it is protected by the surface layer and is not easy to be scratched, and the decorative effect can be achieved for a longer time. Through the arrangement of the rope body, the extensibility of the shoe upper can also be reduced, and the protection of the foot can be strengthened. The rope body is fixed to the bottom layer by locking the yarn, making the rope body not easy to slip and the structure more stable. The manufacturing method of the present invention, in addition to placing the rope body between the surface layer and the bottom layer as in the prior art, also securely locks the rope body to the bottom layer by knitting the locking yarn in loops on the surface layer and in loops on the bottom layer, thereby improving the stability of the upper. In addition, the monofilaments of the surface layer are knitted in intervals and processed with needle transfer, resulting in larger pores in the surface layer. The color of the rope body directly shines through the pores of the monofilaments, giving a 3D visual effect of the rope body being exposed on the upper. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Locking yarn 22 rope body 30 DETAILED DESCRIPTION

[0048] In order to further explain the technical solution of the present invention, it is described in detail below with reference to embodiments.

[0049] Reference Figures 1 to 4 A knitted shoe upper with a three-dimensional effect comprises a shoe upper body and a rope body 30 arranged in the shoe upper body. Figure 1 The figure shows the upper body unfolded. The upper body comprises a composite (specifically, woven together via a flat knitting machine) surface layer 20 and a base layer 10, with the rope 30 positioned between them. The surface layer 20 is knitted from monofilaments 21 and includes locking yarns 22, which are interwoven with the surface layer 20 and base layer 10 to secure the rope 30 to the base layer 10. In conventional shoe uppers, the rope is sandwiched between the surface layer and base layer. While this clamping action between the surface layer and base layer provides some positional restraint, the rope suffers from poor stability and is prone to slippage under stress. Preferably, the diameter of the monofilaments 21 is 0.2 mm or less, while the rope 30 has a larger diameter than the monofilaments 21 and a diameter of 5 mm or less.

[0050] As a preferred embodiment of the present invention, the surface layer 20 is provided with a plurality of mesh holes. Such mesh holes can be formed naturally by weaving with conventional weaving equipment due to the small diameter of the monofilament, or can be formed by a mesh jacquard structure.

[0051] As a preferred embodiment of the present invention, the monofilament 21 is a transparent monofilament. As a preferred embodiment of the present invention, the monofilament 21 is a polyester monofilament, a nylon monofilament, a polypropylene monofilament or a TPU monofilament.

[0052] As a preferred embodiment of the present invention, the base layer 10 is interwoven with polyester high-stretch yarn, polyester low-stretch yarn, or nylon yarn. As a preferred embodiment of the present invention, the polyester high-stretch yarn has a specification of 75D / 36F, the polyester low-stretch yarn has a specification of 150D / 36F, and the nylon yarn has a specification of 70D. "D" in this invention is also known as the denier in the industry and refers to the weight (in grams) of 9000 meters of yarn. "F" in this invention refers to the number of microfibers in a single yarn.

[0053] As a preferred embodiment of the present invention, the diameter of the monofilament 21 is 0.1 mm to 0.15 mm, and the diameter of the rope body 30 is 0.8 mm to 1.6 mm.

[0054] As a preferred embodiment of the present invention, the rope body 30 is a colored rope body 30 , for example, a black rope body 30 or a colored rope body 30 .

[0055] As a preferred embodiment of the present invention, the surface layer 20 includes a plurality of coil rows, which are nested together in the longitudinal direction, each coil row includes a plurality of coils arranged in the transverse direction, and the rope body 30 extends in the transverse direction.

[0056] As a preferred embodiment of the present invention, the upper body includes a forefoot portion 15 corresponding to the front of the sole and a first heel portion 13 and a second heel portion 14 corresponding to the heel. The forefoot portion 15 is connected to the first heel portion 13 via a first connecting portion 11, and the forefoot portion 15 is connected to the second heel portion 14 via a second connecting portion 12. A tongue opening 16 for mounting the tongue and a shoe opening 17 for allowing the foot to enter the shoe are formed between the first connecting portion 11 and the second connecting portion 12. When the upper body is mounted on the sole, the first heel portion 13 and the second heel portion 14 are connected together to form the heel portion of the upper.

[0057] As a preferred embodiment of the present invention, there are multiple ropes 30, with the direction from the first connecting part 11 to the second connecting part 12 being the left and right direction. The multiple ropes 30 are arranged along the left and right directions of the upper body, and the ropes 30 extend along the front and back directions of the upper body.

[0058] The present invention also provides a method for manufacturing a knitted shoe upper with a three-dimensional effect. Figure 3 In the figure, the symbol designated by M represents knitting in a loop on the front needle bed, the symbol designated by N represents knitting in a loop on the rear needle bed, the symbol designated by P represents transferring the coil on the needle of the front needle bed to the rear needle bed by turning the needle, and the symbol designated by S represents knitting in a loop on the front needle bed. The present application adopts a flat knitting machine with a front needle bed and a rear needle bed for knitting the shoe upper. The flat knitting machine has a first yarn mouth carrying yarn A, a second yarn mouth carrying yarn B, a third yarn mouth carrying yarn C, and a fourth yarn mouth carrying yarn D. The first yarn mouth carries yarn A to weave the surface layer 20 on the front needle bed, and the second yarn mouth carries yarn B to weave the bottom layer 10 on the rear needle bed. Yarn A is a monofilament, and yarn C is a rope body. The diameter of the rope body 30 is larger than the diameter of the monofilament 21. At the position where the rope body 30 needs to be laid out, the third yarn mouth carries yarn C to pull the floating line. The floating line of this application is a tensioned straight line. The fourth yarn mouth carries yarn D to weave a loop on the bottom layer 10, and a tuck loop is weaved on the surface layer 20 and the rope body is locked on the bottom layer 10. Yarn D is a locking yarn.

[0059] As a preferred embodiment of the present invention, 52 weaving rows form a cycle unit in the upper, and the weaving method of 52 weaving rows is as follows:

[0060] The first knitting row is the surface knitting of yarn A, using spacer needles;

[0061] The second knitting row uses yarn B as the bottom layer, and is knitted using spacer needles. The knitting position is offset by one needle position compared to the first knitting row.

[0062] The third knitting row is knitted with yarn A as the surface layer, using spacer needles, and is offset by one needle position compared to the first knitting row;

[0063] The fourth knitting row is knitted with yarn B as the bottom layer, using spacer needles, and is offset by one needle position compared to the second knitting row;

[0064] The 5th and 6th knitting rows are to transfer the loops of the corresponding front needle bed needles to the needles of the rear needle bed by needle transfer;

[0065] The knitting action from row 7 to row 12 is the same as that from row 1 to row 6, but the knitting needle position is offset by 1;

[0066] The knitting action of the 13th to 18th rows is the same as that of the 1st to 6th rows;

[0067] The 19th knitting row is knitted with yarn A as the surface layer, using spacer needles;

[0068] The 20th knitting row is knitted with yarn B as the bottom layer, using spacer needles, and is offset by one needle position compared to the 19th knitting row;

[0069] The 21st knitting row is knitted with yarn A as the surface layer, using spacer needles;

[0070] The 22nd and 23rd knitting rows are the kicking actions of C yarn to adjust the yarn feeder position;

[0071] The 24th knitting row is for C yarn to do the floating line action;

[0072] The 25th knitting row is where yarn D is looped on the bottom layer and tucked on the top layer, using spacer knitting to secure yarn C to the bottom layer. The locking yarn 22 is used to bind the rope 30 to the bottom layer to prevent the rope from being woven and causing damage to the knitting needles.

[0073] The 26th row is the bottom knitting of yarn B on the tuck needle position of the 25th row;

[0074] The knitting action of rows 27 to 47 is the same as that of rows 1 to 21, but the knitting position is offset by one needle position.

[0077] The 51st knitting row is where yarn D is looped on the bottom layer and tucked on the top layer, using spacer knitting to fix yarn C on the bottom layer.

[0078] The 52nd knitting row is the bottom knitting made by yarn B on the tuck needle position of the 51st knitting row.

[0079] After the fabric is woven, it undergoes a high-temperature treatment. For fabrics without heat-melting threads, this high-temperature treatment allows the fabric to fully shrink and achieve the desired fabric effect. For fabrics with heat-melting threads, this high-temperature treatment is required to melt the threads and bond them to the fabric interior, achieving the desired fabric effect.

[0080] The present invention can directly weave the shoe upper shape, and can also weave into fabric and then cut into the shoe upper shape by cutting.

[0081] The product form of the present invention is not limited to the embodiments of this case. Any appropriate changes or modifications made by anyone with similar ideas should be deemed to be within the patent scope of the present invention.
