[0040] The core of the present application is to provide a woven shoe body and a weaving method thereof, so that the woven shoe body is integrally woven and formed without splicing, thereby shortening the production process and reducing the production steps.

[0041] ​​​The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0042] The woven shoe body is folded and knitted integrally by a four-needle bed computerized flat knitting machine with diagonally arranged island precision MACH2XS153-12G type four-needle beds, as shown in the drawings. Figure 3 The device has four needle beds, i.e., front lower needle bed 10, rear lower needle bed 20, front upper needle bed 30 and rear upper needle bed 40, and the four needle beds are arranged in a diagonal "X" shape. Compared with a common two-needle bed flat knitting machine, the four-needle bed flat knitting machine has more advantages in tubular folding knitting. In the present application, the main knitting area is between the front lower needle bed 10 and the rear lower needle bed 20, and the front upper needle bed 30 and the rear upper needle bed 40 only play a holding and auxiliary role in adjusting the fabric density, local knitting and needle turning (the needle turning is diagonal needle turning, i.e., the front lower needle bed 10 and the rear upper needle bed 40, and the rear lower needle bed 20 and the front upper needle bed 30 turn with each other). The main knitting area in the following is between the front lower needle bed 10 and the rear lower needle bed 20. As shown in the drawings, Figures 1-3 The woven shoe body is folded and knitted integrally by a four-needle bed computerized flat knitting machine with diagonally arranged island precision MACH2XS153-12G type four-needle beds, as shown in the drawings.

[0043] Among them, the toe area 105 is responsible for providing protection to the toes, preventing injury, while providing comfort, avoiding squeezing or limiting the movement of the toes. The tongue area 104 prevents dust, small stones and other foreign matter from entering the shoe, while providing additional comfort, reducing direct friction of the shoelace and the upper on the foot. The heel area 101 is responsible for providing support to the heel, helping to maintain the stability and balance of the foot, while having a shock-absorbing function, which can reduce the impact on the foot during walking and running. The sole area 102 is responsible for supporting the foot, while maintaining the overall structure of the shoe, maintaining the shape of the shoe, ensuring the durability of the shoe. The side area 103 of the upper connects parts such as the sole area 102 and the tongue area 103, ensuring that the shoe is tightly fixed on the foot, avoiding the foot from sliding in the shoe.

[0044] The woven shoe body disclosed by the present application includes basic yarn and hot melt yarn in the knitted yarn, and the basic yarn includes but is not limited to polyester filament, nylon filament, and also can be one or more of cotton yarn, blended fiber, and polyester plus spandex. The hot melt yarn can be fused and solidified at a certain temperature to support the shape of the woven shoe body, so that the woven shoe body remains firm. The specific type of hot melt yarn includes but is not limited to polyester hot melt yarn, nylon hot melt yarn and tpu monofilament.

[0045] In a specific embodiment of the present application, the yarns of the knitted shoe body include five types, which are elastic thread, high-strength polyester multifilament and polyester multifilament, tpu monofilament, nylon monofilament and polyester monofilament. For the convenience of description, hereinafter, the elastic thread is denoted as yarn A, the high-strength polyester multifilament is denoted as yarn B1, the polyester multifilament is denoted as yarn B2, the tpu monofilament is denoted as yarn C, the nylon monofilament is denoted as yarn D, and the polyester monofilament is denoted as yarn E, wherein the hot melting temperature of the tpu monofilament is between 100℃ and 150℃, the diameter of the yarn D is 0.1mm-0.5mm, and the diameter of the yarn E is 0.1mm-0.5mm.

[0046] The embodiment of the present application discloses a weaving method of a knitted shoe body, as shown in the figure, which comprises the following steps: Figure 10

[0047] Step S10, the shoe body preform is knitted.

[0048] According to the structure diagram of the knitted shoe body, it should be noted that the structure diagram of the knitted shoe body includes a first part and a second part, and both the first part and the second part include a heel area 101, a sole area 102, a shoe upper side area 103, a tongue area 104 and a toe area 105 of the knitted shoe body. The front lower needle bed 10 and the rear lower needle bed 20 respectively knit the front and back surface tissues of the first part and the second part, and finally knit the closing at the joint of the first part and the second part. The front upper needle bed 30 and the rear upper needle bed 40 assist in adjusting the density of the knitted layer, local knitting and needle turning, so that each area of the knitted shoe body is integrally knitted and formed, and the shoe body preform is formed.

[0049] Step S20, the shoe body is shaped.

[0050] The shoe body preform after being taken off the machine is appropriately cut and trimmed to remove the excess waste yarn and waste material part, and then is sleeved into a shoe body mold of appropriate size, the tightness of the entire fabric is adjusted, and heat setting is performed at an appropriate temperature to fix the shape of the knitted shoe body and enhance the stability of the shoe body.

[0051] The weaving method of the knitted shoe body disclosed by the embodiment of the present application integrally knits and forms each area of the knitted shoe body, which is seamless knitting and does not need to be stitched later. Compared with the traditional process, the area of the generated waste yarn is small, and excessive cutting and splicing are not needed, which simplifies the process flow, reduces the waste of raw materials and labor cost. At the same time, the design and style of the integrally knitted shoe body can be more trendy and modern, which brings better fashion experience to consumers. At the same time, integrally knitted and formed can effectively prevent friction and wear. Computer flat knitting machine knitting can reduce manual errors, improve production efficiency and product consistency, and provide the possibility for rapid response to market changes. The integrally knitted shoe upper has better air permeability, lightweight characteristics and better fit, which can reduce the burden of the wearer during exercise, improve flexibility and speed. ​

[0052] In one embodiment of the present application, the first portion and the second portion of the knitted shoe body are spaced apart along a center axis of the knitted shoe body. As shown in the figure, the dashed line represents the center axis of the knitted shoe body, which refers to the most symmetrical dividing line of the left and right sides of the knitted shoe body in the length direction of the knitted shoe body. Taking the right shoe as an example, the toe area is inclined to the left, so the left and right sides are not completely symmetrical, and the center axis here refers to the most symmetrical dividing line of the left and right sides. Figure 2 Figure 3 The center is a schematic view after folding along the center axis of the knitted shoe body, that is, the first portion or the second portion. During knitting, the first portion and the second portion are folded, and the front lower needle bed 10 and the rear lower needle bed 20 knit the front and back face structures of the first portion and the second portion, respectively.

[0053] The knitting method of the knitted shoe body disclosed in the embodiment of the present application further comprises steps S1-S2 before the shoe body preform is knitted in step S10.

[0054] Step S1, drawing a structure diagram;

[0055] Draw the structure diagram of the knitted shoe body, which is a side structure diagram of the knitted shoe body;

[0056] Step S2, setting the structure of the knitted shoe body;

[0057] Divide the heel area 101, the sole area 102, the two side areas 103 of the upper, the tongue area 104 and the toe area 105 of the knitted shoe body on the side structure diagram of the knitted shoe body, and set the structure of each area. It should be noted that the structure here is a single or double loop structure composed of structure units such as loop formation, loop collection and float, or by knitting methods such as loop transfer, needle selection, needle lifting, etc. according to certain rules. Different structures have different properties, thereby affecting the appearance and performance of the shoe upper. It should be noted that the side structure diagram also includes a waste yarn area, which is used to protect and isolate the main structure, adjust and test the knitting of the machine, as shown in the seventh area 7 and the twelfth area 12. Figure 3

[0058] The knitting method of the knitted shoe body disclosed in the embodiment of the present application uses the island precision computer flat knitting machine programming software SDS-ONE APPEX3 to design the structure of each area.

[0059] ​​It should be noted that when weaving a shoe body, steps S1-S2 are operated once, and the file format of the program generated by the computer flat knitting machine capable of reading is stored in the U disk, and the program is input into the computer flat knitting machine to weave the shoe body preform. Different designs and different sizes of woven shoe bodies are woven, and steps S1-S2 need to be re-operated, and the program imported by the computer flat knitting machine can be read.

[0060] The weaving method of the woven shoe body disclosed in the embodiment of the application is woven from the heel area 101 of the woven shoe body to the toe area 105 of the woven shoe body when the front lower needle bed 10 and the rear lower needle bed 20 weave the front and back surface structures of the first part and the second part respectively.

[0061] The weaving method of the woven shoe body disclosed in the embodiment of the application is woven from the heel area 101 of the woven shoe body to the toe area 105 of the woven shoe body when the front lower needle bed 10 and the rear lower needle bed 20 weave the front and back surface structures of the first part and the second part respectively.

[0062] In a specific embodiment of the application, the structure diagram of each region is as shown in Figure 4 It should be noted that the ninth region 9 in the figure represents a local weaving process, and there is no specific structure. The tenth region 10 in the figure is the heel area 101. Since the shape of the heel area 101 is irregular, the structure is in an inclined state, and the length of each course is different. At the beginning, only a small number of needles weave the structure. With the weaving of each course, more and more needles participate in the weaving, so that the length gradually increases. Then it is slowly inclined, and finally it is slowly reduced when it is closed, so the length is shortened. Therefore, the local weaving method is adopted. When the main part of the heel area 101 is woven, normal weaving is performed. It should be noted that local weaving refers to the process in which some needles temporarily stop weaving, and the other part of the needles weaves. When the weaving is stopped, the loop remains on the needle; and when needed, the stopped needle re-enters the weaving. Before weaving the heel area 101, a waste yarn area is first woven, as shown in the twelfth region 12 in Figure 4 , to prevent the tensioning roller from causing excessive tension on the shoe body structure, Figure 3 The arrow in the figure indicates the tensioning direction of the tensioning roller. Specifically, the twelfth region 12 uses a No. 1 yarn nozzle to feed yarn B2 for weaving.

[0063] When weaving the heel area 101, the shoe opening part area is first woven, as shown in Figure 4The eleventh region 11 is shown, yarn A is fed by using No. 2 yarn guide (for guiding yarn, feeding yarn directly to the knitting needle), the stitch is rib stitch, preventing curling and falling apart. Then yarn B1 and yarn B2 are fed by using No. 3 yarn guide, yarn C is fed by using No. 4 yarn guide, and yarn D and yarn E are fed by using No. 5 yarn guide. Yarn A is knitted by using tuck stitch, located inside, increasing the thickness of the stitch, close to the skin, improving the touch, yarn C does not participate in the knitting of the main structure, only fills in the inside of the stitch, facilitating the subsequent hot melt setting, and improving the stability of the structure; yarn D and yarn E are knitted as spacer yarn and float yarn in the stitch, repeatedly interlaced on the front and back of the fabric.

[0064] After the toe portion is knitted, four courses are taken as one small cycle, the first and second courses are alternately looped and tacked by the front lower needle bed 10 and the rear lower needle bed 20, the third course is to alternately tuck the float yarn by the front lower needle bed 10 and the rear upper needle bed 40, and the last course is to knit two degrees of stitches to adjust the density. Then, based on the four courses, two cycles are knitted by the front lower needle bed 10, and two cycles are knitted by the rear lower needle bed 20. When the different needle beds are alternated, no needle transfer is needed, and when the same needle bed is alternated, one needle is spaced. After 4 small cycles, i.e. 16 courses, are knitted, the last three courses of the large cycle are completed. In the last three courses, the first course and the third course are alternately looped and spaced by the front lower needle bed 10 and the rear lower needle bed 20, and the second course is to alternately tuck the float yarn by the front lower needle bed 10 and the rear upper needle bed 40. Then, the knitting of a new large cycle is restarted until the entire heel region 101 is formed. The heel region 101 has uniform and thick stitches, which can closely fit the heel, provide sports support, and keep the wearer comfortable. It should be noted that the stitch structure of the heel region 101 selects yarn A, i.e. the rubber band, to tuck, which not only can increase the thickness of the stitch and improve the hand feeling, but also can give the stitch certain elasticity and reduce friction. At the same time, the yarn C filled in the stitch also increases the thickness. In actual weaving, the rubber band can also be selected as other yarns as long as it has the same effect.

[0065] It should be noted that in actual weaving, the selection of yarn guide is determined according to the style of the knitted shoe body and the characteristics of the fabric, and is not limited to the number and arrangement of the yarn guides described above.

[0066] After the heel region 101 is knitted, the No. 2 yarn guide and the No. 4 yarn guide are temporarily disabled, and yarn A and yarn C are no longer fed. A small amount of yarn C is added to the yarn B1 and yarn B2 of the No. 3 yarn guide to knit together. When the toe region 104 and the side region 103 of the upper meet, the No. 4 yarn guide is reactivated to feed yarn C. As Figure 3The shown organization zoning chart, the sole area 102 includes two kinds of organization structure of first area 1 and second area 2, the surface filament structure of first area 1 is fixed by the bottom monofilament, and the appearance shows as small diamond effect. Figure 5 As shown, the first and second columns are knitted with yarn D and yarn E fed by the 5th yarn nozzle, and every other stitch is knitted, and the remaining stitches are not knitted; the third column is knitted with yarn B2 and a small amount of yarn C fed by the 3rd yarn nozzle, and every stitch is knitted.

[0067] The main structure of the organization of the second area 2 is plain stitches on the front side, and on the back side, part of the yarn is not knitted and forms floats, while the monofilament (yarn D and yarn E) acts as a spacer yarn and is repeatedly inserted on the front and back sides of the fabric. As shown, Figure 6 As shown, the first to third columns are knitted with yarn B2 and a small amount of yarn C fed by the 3rd yarn nozzle. Among them, the first column is full stitch; the second column is every other stitch, and the remaining stitches are not knitted; the third column is every other stitch based on the second column, and the remaining stitches are not knitted. The fourth and fifth columns are knitted with monofilament (yarn D and yarn E) fed by the 5th yarn nozzle, the fourth column is every other stitch, and the remaining stitches are not knitted; the fifth column is every other stitch based on the fourth column, and the remaining stitches are not knitted.

[0068] The two side areas 103 of the upper include three kinds of organization structure, as shown in Figure 3 The third area 3, the fourth area 4, and the eighth area 8 are shown in the middle. Among them, the organization structure of the third area 3 is the same as that of the first area 1. The surface multifilament of the fourth area 4 is fixed by the bottom monofilament in the form of tuck stitches, and there are three longitudinal rows of plain stitches between two longitudinal rows of tuck stitches, and the back spacer yarn is more obvious, which shows as large diamond effect on the appearance, and along the toe area 105, it presents an inverted U shape, which can improve the air permeability. As shown, Figure 7 As shown, the first and fourth columns are knitted with yarn B2 and a small amount of yarn C fed by the 3rd yarn nozzle, and the second to third columns and the fifth to sixth columns are knitted with monofilament (yarn D and yarn E) fed by the 5th yarn nozzle. The first column is full stitch; the second and third columns are every three stitches not knitted once, and the remaining stitches are knitted; the fourth column is interlaced with knitted stitches and tuck stitches, and one stitch is not knitted between each knitted stitch and tuck stitch; the fifth and sixth columns are also every three stitches not knitted once, and the remaining stitches are knitted, but the arrangement is staggered by two stitches from the second to third columns. As a transition area, the two side areas 103 of the upper are uniformly dense and stable support. Some stitches are stretched and pressed, and the appearance presents uneven effect.

[0069] The weaving method of the woven shoe body disclosed in the embodiment of the present application is that the tongue area 104 and the two side areas 103 of the vamp are integrally woven and formed or separately woven and then combined by weaving, that is, the woven shoe body includes two types, one is an integral tongue and the other is a split tongue.

[0070] Figure 4 The eighth area 8 in the above formula is the junction of the tongue area 104 and the two side areas 103 of the vamp, the structure of which is basically the same as that of the first area 1 and the third area 3, but at this time, the No. 4 yarn nozzle is re-enabled to feed the yarn C as a lining structure, so that the area can be hardened after heat setting to prevent curling.

[0071] When the tongue area 104 and the two side areas 103 of the vamp are an integral structure, the No. 6 yarn nozzle and the No. 7 yarn nozzle do not need to be enabled, and the yarn B1 and the yarn B2 of the No. 3 yarn nozzle, the yarn C of the No. 4 yarn nozzle and the yarn D and the yarn E of the No. 5 yarn nozzle are woven.

[0072] The weaving method of the woven shoe body disclosed in the embodiment of the present application is that when the tongue area 104 is a split tongue, the connection between the tongue area 104 and the two side areas 103 of the vamp is staggered in space, as shown in the following formula: Figure 8 The A area represents the edge structure of the tongue area, the B area represents the connection between the tongue area and the edge, the middle part of the tongue area 104 is directly connected with the edge structure, and the two sides of the tongue area 104 are covered by the edge structure, which is a double-layer three-dimensional structure. Therefore, when weaving the tongue area 104, the computer flat knitting machine creates an independent weaving area for local multi-layer three-dimensional weaving of the tongue area 104, and the remaining part is placed on the auxiliary needle bed for temporary non-weaving, and after the tongue area 104 is woven, the two are combined for continuous weaving.

[0073] Specifically, the yarn B2 is fed by the No. 6 yarn nozzle to weave the waste yarn area, and then the yarn B1 and the yarn B2 are fed by the No. 7 yarn nozzle to weave the main part of the tongue area 104. As shown in the following formula: Figure 4The tongue area 104 includes two kinds of structures, which are shown as the fifth area 5 and the sixth area 6. The main structure of the fifth area 5 is 2+2 rib structure, in which the front lower needle bed 10 is automatically transferred to the back upper needle bed 40 for knitting, and the front and back are connected to complete one knitting cycle. In the middle area of the tongue area 104, the front lower needle bed 10 is transferred to the back upper needle bed 40 for knitting, and then is transferred back to the front lower needle bed 10 after being shifted left or right by one needle; the back lower needle bed 20 is transferred to the front upper needle bed 30 for knitting, and then is transferred back to the back lower needle bed 20 after being shifted left or right by one needle, thereby forming a hole effect. The main structure of the sixth area 6 is 1+1 rib structure with floating lines, in which four longitudinal lines are one knitting cycle, and are respectively reverse loops, front loops and two floating lines. In the distribution of upper and lower lines, the loops and the floating lines are staggered.

[0074] When the tongue area 104 is connected with the side area 103, the knitting is performed by the back lower needle bed 20, the back lower needle bed 20 is transferred to the front upper needle bed 30 for knitting, the next two lines are shifted left by one needle, and then are transferred to the back lower needle bed 20 for knitting, and the back lower needle bed 20 is transferred to the front upper needle bed 30 to complete the narrowing.

[0075] When the toe area 105 is knitted, the yarn B1 and the yarn B2 and a small amount of yarn C are fed by the No. 3 yarn guide, and the yarn D and the yarn E are fed by the No. 5 yarn guide. The main structure includes the second area 2 to the fourth area 4. The main structure of the second area 2 is plain knitting on the front side and floating lines on the back side, and the monofilament (the yarn D and the yarn E) is used as a padding yarn and repeatedly inserted between the front and back sides of the fabric. The surface multifilament structure of the third area 3 is fixed by the bottom monofilament, and appears as a small diamond effect in appearance. The surface multifilament of the fourth area 4 is fixed by the bottom monofilament in the form of tuck, and there are three longitudinal lines of plain knitting between two longitudinal lines of tuck, and the back padding yarn is more obvious, which appears as a large diamond effect in appearance. At the junction of the plain knitting and the small diamond, the front lower needle bed 10 is transferred to the back upper needle bed 40 for knitting, and the back lower needle bed 20 is transferred to the front upper needle bed 30 for knitting. Then, the two lines are shifted left by two needles, and are transferred back to the front lower needle bed 10 and the back lower needle bed 20 respectively, and finally are transferred to the back upper needle bed 40 and the front upper needle bed 30. The front lower needle bed 10 is followed by the back lower needle bed 20 for knitting for two degrees, and then the front lower needle bed 10 is knitted for two degrees, so as to adjust the density and complete the narrowing.

[0076] The knitting method of the woven shoe body disclosed in the embodiment of the present application adopts the rotary knitting method when the first part knitted by the front lower needle bed 10 and the second part knitted by the rear lower needle bed 20 are closed at the joint. Since the shoe body is folded during knitting, the knitting angle of the yarn at the joint of the unfolded toe area 105 is perpendicular to the toes, and the yarn is prone to breakage during knitting and to damage and holes during wearing. Therefore, the rotary knitting method is adopted, as shown in Figure 9 the figure, the organizational loops are only for example, and 200 is the yarn at the joint. In order to make the knitting direction of the yarn vertically flip, the loop yarn at the edge of the front lower needle bed 10 and the loop yarn at the edge of the rear lower needle bed 20 need to be gradually exchanged, that is, the loop yarn at the edge of 200 in the figure, until the knitted body is rotated by 90 degrees and then knitted upward to the last joint.

[0077] It should be noted that each of the embodiments in the present specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the embodiments can be referred to each other.
