Description

Technical Field

[0001] The invention relates to the technical field of knitted shoe uppers, in particular to a knitted shoe upper with a suspended floating thread structure and a manufacturing method thereof. Background Art

[0002] With the vigorous development of the knitting industry, the variety of knitted shoe upper products on the market is becoming more and more abundant, and floating yarn structure is becoming more and more popular in knitted shoe uppers.

[0003] When encountering floating thread tissue in the weaving of knitted uppers, the floating thread is usually used as an intermediate layer and woven between the bottom layer and the surface layer of the upper. Although it has the effect of thickening the upper, the tensile performance of the upper is reduced, the air permeability is poor, and it lacks beauty and perspective. Summary of the Invention

[0004] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention. The purposes and other advantages of the present invention can be realized and obtained through the structures particularly pointed out in the description, claims, and other drawings of the description.

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a knitted upper with a suspended floating thread structure. By utilizing the characteristics of colored yarns and thermoplastic yarns or elastic yarns, an upper with a double knitted structure is woven into one piece, so that the floating thread structure in the upper is presented in the upper in a suspended manner, which not only plays a decorative role, but also has a wrapping role. At the same time, it also greatly increases the air permeability and perspective of the upper, giving people a sense of beauty and perspective.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is: a knitted upper with a suspended floating thread structure, comprising an upper body woven integrally by a knitting device, the upper body comprising a first knitting structure and a second knitting structure; the first knitting structure comprises a first surface layer and a first bottom layer knitted under the first surface layer, the first surface layer is knitted by at least one first yarn, and the first bottom layer is knitted by at least one second yarn; the second knitting structure comprises a suspended floating thread layer woven by at least one third yarn, one end of the suspended floating thread layer is connected to the first surface layer or / and the first bottom layer, and the other end of the suspended floating thread layer is connected to the first surface layer or / and the first bottom layer; the first knitting structure and the second knitting structure are woven together to form the upper body.

[0007] Preferably, a second bottom layer is woven beneath the suspended floating yarn layer, the second bottom layer is woven from at least one fourth yarn, and both ends of the second bottom layer are connected to the first bottom layer.

[0008] Preferably, a second surface layer is woven above the suspended floating yarn layer, the second surface layer is woven from at least one fifth yarn, and both ends of the second surface layer are connected to the first surface layer.

[0009] Preferably, the suspended floating thread layer is woven by an open needle knitting method.

[0010] Preferably, the suspended floating thread layer is woven by using a spacer-needle weaving method.

[0011] Preferably, the spacer knitting method is one of the following: knitting one stitch every three stitches, knitting one stitch every four stitches, knitting one stitch every five stitches, or a combination of two or more. Knitting one stitch every 3-5 stitches makes the density of the suspended floating thread just right. If the spacing is too close, the floating thread will be loose after the loop is cast off. If the spacing is too far, there will be missed stitches at the edge of the tuck.

[0012] Preferably, the first yarn and the second yarn are both colored yarns, and the colored yarns may be polyester high-elastic yarns.

[0013] Preferably, the third yarn is a thermoplastic yarn or an elastic yarn. The thermoplastic yarn may be a TPU yarn, and the elastic yarn may be a low-elastic blended yarn.

[0014] Preferably, the fourth yarn is a transparent yarn, which may be a monofilament.

[0015] Preferably, the fifth yarn is a transparent yarn, which may be a monofilament.

[0016] Preferably, the knitting equipment is a weft knitting machine.

[0017] The present invention also provides a method for manufacturing a knitted shoe upper with a suspended floating yarn structure as described above, comprising the following steps:

[0018] S1. Material preparation: Select the weaving material based on the pattern and style of the upper body;

[0019] S2. Weaving step: Import the corresponding weaving program into the weaving machine, enter the corresponding parameters, and weave the upper body;

[0020] S3 ironing step: Ironing the woven upper body;

[0021] S4. Air cooling step: air cooling the upper body after ironing to form a finished upper.

[0022] The knitting step includes knitting a first knitting structure and knitting a second knitting structure.

[0023] The first knitted structure comprises a first surface layer knitting and a first bottom layer knitting. The first surface layer knitting is knitted with a first yarn for surface knitting and a bottom tuck spacer knitting, or a surface knitting and a flat knitting; the first bottom layer knitting is knitted with a second yarn for bottom knitting and a top tuck spacer knitting, or a spacer bottom knitting.

[0024] The second knitting structure includes the knitting of a suspended float layer, the knitting of a suspended float layer and a second bottom layer, or the knitting of a suspended float layer and a second top layer. The knitting of the suspended float layer is performed by knitting with the third yarn on the empty needles and forming a loop on the front needle bed or the back needle bed, and then performing a knock-over action; the knitting of the suspended float layer and the second bottom layer is performed by knitting with the third yarn on the spacer needles, knitting with the fourth yarn on the bottom knitting and the bottom tuck, and forming a loop on the back needle bed and then performing a knock-over action; the knitting of the suspended float layer and the second top layer is performed by knitting with the third yarn on the spacer needles, knitting with the fifth yarn on the top knitting and the top tuck, and forming a loop on the front needle bed and then performing a knock-over action.

[0025] Preferably, each weaving row of the first surface layer is knitted with one needle position staggered, and each weaving row of the first bottom layer is knitted with one needle position staggered.

[0026] By adopting the above technical solution, the beneficial effects of the present invention are:

[0027] 1. The present invention uses colored yarn to weave a first surface layer and a first bottom layer, and uses thermoplastic yarn or elastic yarn to weave a suspended floating thread layer in the shoe upper. Both ends of the suspended floating thread layer are connected to the first surface layer or the first bottom layer. The middle part of the suspended floating thread layer is completely suspended, which plays a decorative role. The shoe upper has good air permeability, strong wrapping, and a strong sense of perspective.

[0028] 2. The present invention also weaves a second surface layer or a second bottom layer above or below the suspended floating layer. The second surface layer or the second bottom layer is woven with transparent yarn. While ensuring the breathability and perspective of the shoe upper, it also greatly enhances the wrapping of the shoe upper. At the same time, the suspended floating layer can still play a decorative role.

[0029] 3. The present invention adopts different weaving methods to weave the suspended floating thread layer, so that the density of the floating threads in the suspended floating thread layer is just right, which will not cause the floating threads to be too sparse and will not cause the phenomenon of missing stitches at both ends of the suspended floating threads.

[0030] 4. The present invention is woven in one piece, has good air permeability, high structural stability, good perspective effect, good aesthetic effect, strong wrapping, simple production method and high production efficiency.

However, it will be apparent to those skilled in the art that the present invention may be implemented without the specific details or the particular manner described herein.

[0058] Example 1

[0059] This embodiment provides a knitted shoe upper with a suspended floating thread structure, including an upper body knitted in one piece by a weft knitting machine.

[0060] Reference Figure 1 , Figure 1 It is a schematic structural diagram of a knitted shoe upper with a suspended floating thread structure according to the present invention.

[0061] The upper body includes a first knitted structure 1 and a second knitted structure 2 .

[0062] Reference Figure 3 , Figure 3 The cross-section of the knitted shoe upper with suspended floating thread structure of the present invention is Figure 1 .

[0063] The first knitted structure 1 includes a first surface layer 11 and a first bottom layer 12 knitted beneath the first surface layer 11. The first surface layer 11 is knitted with at least one first yarn 111, and the first bottom layer 12 is knitted with at least one second yarn 121. The first yarn 111 and the second yarn 121 are both colored yarns, which may be polyester high-elastic yarns.

[0064] The second knitted structure 2 includes a suspended float layer 21 knitted from at least one third yarn 211. One end of the suspended float layer 21 is connected to the first bottom layer 12, and the other end of the suspended float layer 21 is connected to the first bottom layer 12. The third yarn 211 is a thermoplastic yarn or an elastic yarn. The thermoplastic yarn may be a TPU yarn, and the elastic yarn may be a low-elastic blended yarn.

[0065] The first knitted structure 1 and the second knitted structure 2 are knitted together to form the upper body.

[0066] The suspended floating thread layer 21 is knitted by an open needle knitting method.

[0067] Reference Figure 2 , Figure 2 The present invention is a flow chart of a method for manufacturing a knitted shoe upper with a suspended floating yarn structure.

[0068] This embodiment also provides a method for manufacturing a knitted shoe upper with a suspended floating yarn structure as described above, comprising the following steps:

[0069] S1. Material preparation: Select the weaving material based on the pattern and style of the upper body;

[0070] S2. Weaving step: Import the corresponding weaving program into the weaving machine, enter the corresponding parameters, and weave the upper body;

[0071] S3 ironing step: Ironing the woven upper body;

[0072] S4. Air cooling step: air cooling the upper body after ironing to form a finished upper.

[0073] The knitting step includes knitting a first knitting structure 1 and knitting a second knitting structure 2 .

[0074] The first knitted structure 1 includes a first surface layer 11 and a first bottom layer 12. The first surface layer 11 is knitted with a first yarn 111 for surface knitting and a bottom tuck stitch knitting; the first bottom layer 12 is knitted with a second yarn 121 for bottom knitting and a surface tuck stitch knitting.

[0075] The second knitting structure 2 includes a suspended float layer 21. The suspended float layer 21 is knitted with a third yarn 211 and is knitted with an empty needle. After forming a loop on the front needle bed or the back needle bed, a knock-off action is performed.

[0076] Each weaving row of the first surface layer 11 is staggered by one needle position, and each weaving row of the first bottom layer 12 is staggered by one needle position.

[0077] Reference Figure 4-5 , Figure 4 The present invention is a knitting method for knitting a shoe upper with a suspended floating thread structure. Figure 1 ; Figure 5 This is a physical object of the knitted shoe upper with suspended floating thread structure of the present invention Figure 1 .

[0078] The specific weaving steps are as follows:

[0079] The yarns threaded through yarn feeders A and C are the first yarn 111, the yarns threaded through yarn feeders B and D are the second yarn 121, and the yarns threaded through yarn feeder E are the third yarn 211. The first yarn 111 and the second yarn 121 are both polyester high-elastic yarns, and the third yarn 211 is PPU yarn.

[0080] The first knitting row is to use yarn feeder A to do the top knitting and the bottom tuck knitting with alternate needles.

[0081] The second row is knitted with yarn feeder B for the bottom knit and the top tucks in the same row. The top tucks are knitted in the same row as the bottom knit of the first row. This connects the bottom and top layers, and the bottom and top tucks form an intermediate layer, which thickens the fabric. The bottom knit of the second row is knitted in the same row as the top knit of the first row.

[0082] The third knitting row is to use yarn feeder A to do the top knitting and the bottom tuck knitting with alternate needles.

[0083] In the fourth row, yarn feeder B is used for the bottom knit and the top tuck, with alternate needles knitted. The top tuck is knitted in the same row as the bottom knit in row 3. The bottom knit in row 4 is knitted in the same row as the top knit in row 3. Furthermore, the bottom and top tucks and bottom and top knits in rows 3 and 4 are offset by one needle position from the bottom and top tucks and bottom and top knits in rows 1 and 2. This staggered knitting ensures uniformity on the fabric surface.

[0084] The knitting actions and functions of the 5th to 8th weaving rows are the same as those of the 1st to 4th weaving rows.

[0085] The 9th knitting row is knitted with the E yarn feeder on the open needle. The 10th knitting row is the bottom knitting operation, which connects one end of the third yarn 211 to the second yarn 121. The 14th, 18th, 22nd, and 26th knitting rows are the top knitting operations that fix the third yarn 211 during knitting. The 29th knitting row is the bottom tuck knitting operation, which connects the other end of the third yarn 211 to the second yarn 121.

[0086] The 10th knitting row is a knock-over operation for knocking over the third yarn 211 previously fixed on the front needle bed, thereby forming a suspended float layer 21. It is offset by one needle position from the surface knitting of the 9th knitting row.

[0087] The 11th knitting row is knitted with yarn feeder C for the top knitting and bottom tuck knitting with alternate needles.

[0088] The 12th row is knitted with D yarn feeder for bottom knitting and top tuck knitting with spacer needles, and the top tuck knitting is in the same knitting column as the bottom knitting of the 11th row. The bottom knitting of the 12th row is in the same knitting column as the top knitting of the 11th row.

[0089] The 13th knitting row is knitted with yarn feeder C for the top knitting and bottom tuck knitting with alternate needles.

[0090] The 14th row is knitted with the D yarn feeder for the bottom tuck and the top tuck every other needle. The top tuck is knitted in the same row as the bottom tuck in the 13th row. The bottom tuck and the top tuck in the 14th row are knitted in the same row as the top tuck in the 13th row. At the same time, the bottom and top tuck and the bottom and top tuck in the 13th and 14th rows are offset by one needle position from the bottom and top tuck and the bottom and top tuck in the 11th and 12th rows.

[0091] The knitting action from the 15th to the 18th row is the same as that from the 11th to the 14th row.

[0092] The 19th knitting row is knitted with the E yarn feeder on the open needle. The 10th knitting row is a bottom tuck knitting method that connects one end of the third yarn 211 to the second yarn 121. The 11th, 15th, 19th, 23rd, and 27th knitting rows are top knitting movements that fix the third yarn 211 during knitting. The 28th knitting row is a bottom tuck knitting method that connects the other end of the third yarn 211 to the second yarn 121.

[0093] The 20th knitting row is a knock-off operation for knocking off the loop of the third yarn 211 previously fixed on the front needle bed, thereby forming a suspended float layer 21.

[0094] The knitting action from the 21st knitting row to the 40th knitting row is consistent with the knitting action from the 1st knitting row to the 20th knitting row until the knitting is completed.

[0095] Example 2

[0096] This embodiment provides a knitted shoe upper with a suspended floating thread structure, including an upper body knitted in one piece by a weft knitting machine.

[0097] Reference Figure 1 , Figure 1 It is a schematic structural diagram of a knitted shoe upper with a suspended floating thread structure according to the present invention.

[0098] The upper body includes a first knitted structure 1 and a second knitted structure 2 .

[0099] Reference Figure 6 , Figure 6 The cross-section of the knitted shoe upper with suspended floating thread structure of the present invention is Figure 2 .

[0100] The first knitted structure 1 includes a first surface layer 11 and a first bottom layer 12 knitted beneath the first surface layer 11. The first surface layer 11 is knitted with at least one first yarn 111, and the first bottom layer 12 is knitted with at least one second yarn 121. The first yarn 111 and the second yarn 121 are both colored yarns, which may be polyester high-elastic yarns.

[0101] The second knitted structure 2 includes a suspended float layer 21 knitted from at least one third yarn 211, and a second bottom layer 22 knitted beneath the suspended float layer 21. One end of the suspended float layer 21 is connected to the first surface layer 11, and the other end of the suspended float layer 21 is connected to the first surface layer 11. The second bottom layer 22 is knitted from at least one fourth yarn 221, and both ends of the second bottom layer 22 are connected to the first bottom layer 12. The third yarn 211 is a thermoplastic yarn or an elastic yarn. The thermoplastic yarn can be a TPU yarn, and the elastic yarn can be a low-elastic blended yarn. The fourth yarn 221 is a transparent yarn, which can be a monofilament.

[0102] The first knitted structure 1 and the second knitted structure 2 are knitted together to form the upper body.

[0103] The suspended floating thread layer 21 is woven by using a spacer-needle weaving method.

[0104] This spacer knitting method is one of the following: knitting one stitch every three stitches, knitting one stitch every four stitches, knitting one stitch every five stitches, or a combination of two or more. Knitting one stitch every 3-5 stitches ensures the density of the suspended threads is just right. If the spacing is too close, the threads will be loose after being cast off, and if the spacing is too far, stitches will be missed at the edge of the tuck.

[0105] Reference Figure 2 , Figure 2 The present invention is a flow chart of a method for manufacturing a knitted shoe upper with a suspended floating yarn structure.

[0106] This embodiment also provides a method for manufacturing a knitted shoe upper with a suspended floating yarn structure as described above, comprising the following steps:

[0107] S1. Material preparation: Select the weaving material based on the pattern and style of the upper body;

[0108] S2. Weaving step: Import the corresponding weaving program into the weaving machine, enter the corresponding parameters, and weave the upper body;

[0109] S3 ironing step: Ironing the woven upper body;

[0110] S4. Air cooling step: air cooling the upper body after ironing to form a finished upper.

[0111] The knitting step includes knitting a first knitting structure 1 and knitting a second knitting structure 2 .

[0112] The first knitted structure 1 includes a first surface layer 11 and a first bottom layer 12. The first surface layer 11 is knitted with a first yarn 111 for top knitting and a flat knitting; the first bottom layer 12 is knitted with a second yarn 121 for interlaced bottom knitting.

[0113] The second knitted structure 2 includes a suspended float layer 21 and a second bottom layer 22 .

[0114] The suspended float layer 21 and the second bottom layer 22 are knitted with the third yarn 211 for spacer knitting, and with the fourth yarn 221 for bottom knitting and bottom tuck knitting, and loops are formed on the rear needle bed and then cast-off is performed.

[0115] Each weaving row of the first surface layer 11 is staggered by one needle position, and each weaving row of the first bottom layer 12 is staggered by one needle position.

[0116] Reference Figure 7-10 , Figure 7 The present invention is a knitting method for knitting a shoe upper with a suspended floating thread structure. Figure 2 -a; Figure 8 The present invention is a knitting method for knitting a shoe upper with a suspended floating thread structure. Figure 2 -b; Figure 9 The present invention is a knitting method for knitting a shoe upper with a suspended floating thread structure. Figure 2 -c; Figure 10 This is a physical object of the knitted shoe upper with suspended floating thread structure of the present invention Figure 2 .

[0117] The specific weaving steps are as follows:

[0118] The yarns threaded through yarn feeders A and C are first yarn 111, the yarns threaded through yarn feeders B and D are second yarn 121, the yarns threaded through yarn feeder E are fourth yarn 221, and the yarns threaded through yarn feeder F are third yarn 211. The first yarn 111 and the second yarn 121 are both polyester high-elastic yarns, the third yarn 211 is a low-elastic blended yarn, and the fourth yarn 221 is a monofilament.

[0119] The first knitting row is to use yarn feeder A to do top knitting and four-level knitting alternately. The second knitting row is to use yarn feeder B to do interlaced bottom knitting.

[0120] The third row is knitted with yarn feeder A alternating between top knitting and flat knitting. The fourth row is knitted with yarn feeder B using alternate needles. The knitting method is the same as for rows 1 and 2, but with one needle position offset. This offset knitting creates a smoother upper.

[0121] The knitting action of the 5th to 8th knitting rows is the same as that of the 1st to 4th knitting rows.

[0122] The 9th and 10th knitting rows are to transfer the surface knitting on the corresponding front bed needles to the bottom knitting, thereby converting the double-layer structure into a single-layer structure. Because the surface layer of the knitting area needs floating yarn and the bottom layer needs knitting, the double layer becomes a single-layer bottom.

[0123] The 11th knitting row is knitted with yarn feeder C alternating between top knitting and flat knitting. The 12th knitting row is knitted with yarn feeder D alternating between bottom knitting and interlaced knitting.

[0124] Row 13 uses yarn feeder C for alternating top knitting and flat knitting. Row 14 uses yarn feeder D for alternate bottom knitting. The knitting method is the same as rows 11 and 12, but with one needle offset. This offset knitting creates a smoother upper.

[0125] The 15th and 16th rows are knitted alternately by the E yarn feeder for bottom knitting and bottom tuck knitting, wherein the top tuck knitting in the 14th and 29th rows is for strengthening the connection between the fourth yarn 221 and the first knitting structure 1.

[0126] The 17th knitting row is a spacer knitting with three empty knits per row on the F yarn feeder, and the 30th knitting row is for the purpose of Strengthening the connection between the third yarn 211 and the first knitting structure 1 .

[0127] The 18th and 19th knitting rows are knitted alternately by the E yarn feeder for bottom knitting and bottom tuck knitting, wherein the bottom tuck knitting in the 14th and 29th knitting rows is for strengthening the connection between the fourth yarn 221 and the first knitting structure 1.

[0128] The 20th knitting row is to knit the corresponding front bed needle surface stitch to form a floating line. The surface knitting of the F yarn mouth is to fix the third yarn 211. After the fixed point is cast off, the third yarn 211 becomes a very long floating line.

[0129] The 21st knitting row is a spacer knitting with three empty knitting needles per row by the F yarn feeder. The knitting position is one needle away from the 17th knitting row. In order to fix the third yarn 211 and prevent the floating line from affecting the subsequent knitting, the 13th knitting row is for the purpose of Strengthening the connection between the third yarn 211 and the first knitting structure 1 .

[0130] The 22nd and 23rd knitting rows are the kicking actions to bring yarn feeders E and F to a safe position.

[0131] The 24th knitting row is knitted alternately with yarn feeder A for top knitting and flat knitting. The 25th knitting row is knitted alternately with yarn feeder B for bottom knitting.

[0132] The 26th row is knitted with yarn feeder A alternating between top knitting and flat knitting. The 27th row is knitted with yarn feeder B alternating between bottom knitting and interlaced knitting. The knitting method is the same as that of rows 24 and 25, but with one needle position offset.

[0133] The 28th and 29th knitting rows are the yarn feeder kicking actions to bring the E and F yarn feeders to the knitting position.

[0134] The 30th and 31st knitting rows are knitted alternately by the E yarn feeder for bottom knitting and bottom tuck knitting, wherein the top tuck knitting in the 14th and 29th knitting rows is to strengthen the connection between the fourth yarn 221 and the first knitting structure 1.

[0135] The 32nd knitting row is to knit the corresponding front bed needle surface loop to make the floating thread take shape.

[0136] The 33rd knitting row is the spacer knitting with the F yarn feeder doing one needle for every three empty knits, and the surface tuck knitting in the 30th knitting row is to strengthen the connection between the third yarn 211 and the first knitting tissue 1.

[0137] The 34th and 35th knitting rows are knitted alternately by the E yarn feeder for bottom knitting and bottom tuck knitting, wherein the bottom tuck knitting of the 14th and 29th knitting rows is to strengthen the connection between the fourth yarn 221 and the first knitting structure 1.

[0138] The 36th knitting row is to knit the corresponding front bed needle surface loop to make the floating thread take shape.

[0139] The 37th knitting row is a spacer knitting with the F yarn feeder doing one needle for every three empty knitting stitches. The surface knitting position is offset by one needle position from the 33rd knitting row. The surface tuck knitting in the 13th knitting row is to strengthen the connection between the third yarn 211 and the first knitting structure 1.

[0140] The knitting action of the 38th to 41st knitting rows is the same as that of the 11th to 14th knitting rows.
