Description

Technical Field

[0001] This invention relates to the field of flat knitting fabric technology, specifically to a breathable flyknit shoe upper and its production method. Background Technology

[0002] A flat knitting machine is a type of weft knitting machine. Flyknitted shoe uppers can currently be knitted using a computerized flat knitting machine. The knitting-related actions are pre-programmed into a configuration program, which can be imported into the computerized flat knitting machine to achieve automatic knitting.

[0003] Existing flyknit uppers form a mesh structure at the toe that improves breathability through shifting loops. The distribution area is usually a rounded isosceles trapezoid. In other words, the existing configuration process for forming a mesh structure by shifting loops only requires adjusting the spacing between adjacent mesh structures according to different shoe sizes to create a uniform flyknit upper that fits different shoe sizes.

[0004] However, for different foot shapes, especially due to the different positions of the toes in contact with the shoe upper and the different arch shapes that guide the shoe upper to bend, the distribution of ventilation holes in the breathable mesh is difficult to adapt to. Some ventilation holes cannot effectively achieve their ideal breathability because they are continuously blocked by the toes.

[0005] To address the aforementioned issues, a breathable flyknit shoe upper and its production method are proposed. Summary of the Invention

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a breathable flyknit shoe upper and a production method thereof.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a breathable flyknit upper, comprising a breathable surface having a plurality of arrayed breathable holes formed thereon, and further comprising:

[0008] Support strips are provided on the breathable surface, and a plurality of the support strips are distributed around the breathable holes. The two ends of the support strips point to two adjacent breathable holes respectively, and the support strips have a structure that is recessed into the surface of the breathable surface.

[0009] An air guide plate is disposed on a breathable surface. Several air guide plates are distributed around several breathable holes. The middle section of the air guide plate is raised in a direction away from the breathable surface. The air guide plate and the breathable surface surround each other to form a connected air inlet and air outlet. The air outlet is disposed closer to the breathable hole than the air inlet. The cross-sectional area of ​​the air guide plate decreases unidirectionally along the direction from the air inlet to the air outlet.

[0010] The air guide vanes and support strips are distributed on both sides of the air-permeable surface. The air vents are stretched in the direction of the adjacent air outlet to form their cross-sectional shape. The yarn density of the air guide vanes is greater than that of the air-permeable surface. The air-permeable surfaces on both sides of the air guide vanes converge towards the middle section of the air guide vanes. The air-permeable surface is symmetrically provided with two air guide vanes arranged in opposite directions within the smallest area formed by several support strips. The two air guide vanes have a structure with a large distance between the middle section and a narrow distance between the two sides.

[0011] The invention is further configured such that: the breathable surface is woven by a flat knitting machine having three needle beds with needles installed, the three needle beds being a front bed, a back bed, and an auxiliary bed, the front bed and the back bed weaving to form the breathable surface and several support strips, the auxiliary bed weaving synchronously with the other two needle beds and forming several air guides through weaving, the air guides forming a single-sided structure.

[0012] The present invention is further configured such that: the breathable surface is woven to form a single-sided structure at the position covered by the air guide plate, and the breathable surface positions between adjacent air guide plates are connected to the single-sided structures on both sides by non-woven structures.

[0013] The invention is further configured such that: the support strip has a double-sided structure, both sides of the support strip are connected to the breathable surface and the air guide plate in a loop, the middle position of the support strip is woven with two support yarns of different weights, and the support strip has a loop connection with the breathable surface at the end near the air hole, with the support yarn of relatively higher weight woven on the same side as the breathable surface where the air guide plate is located.

[0014] The present invention is further configured such that: the edge position of the breathable surface near the breathable hole is woven into a plurality of shifting ring structures in the direction away from the breathable hole, so as to form a stretching of the breathable hole structure.

[0015] The present invention is further configured such that: a plurality of the support strips and air guides are evenly distributed around a plurality of air vents, and the two sides of the air guides are smoothly connected to the concave positions of the adjacent support strips.

[0016] A method for producing a breathable flyknit shoe upper, used to produce the aforementioned flyknit shoe upper, includes the following steps:

[0017] S1: The breathable surface of the flyknit upper is divided into areas using a pattern-making program. Based on the spacing of several breathable holes in each area, the position and structure of the support strip and air guide plate are set in each area to form a weaving program. S1 achieves the setting of the spacing between adjacent breathable holes through the following sub-steps:

[0018] S1.1: Based on the distribution characteristics of the toe contact area of ​​different foot types and the shape of the arch of the foot, the breathable surface is selected and divided into multiple areas, including the toe breathable area, the arch guiding area and the side stability area.

[0019] S1.2: Different ventilation hole distributions are adopted for different areas. Several ventilation holes in the dorsal toe ventilation area are radially distributed with gradually increasing spacing. Several ventilation holes in the arch guidance area are densely distributed with the same spacing. Several ventilation holes in the lateral stability area are sparsely distributed with the same spacing.

[0020] S2: Select yarns with different counts and properties to knit breathable surfaces, support strips and air guides, and equip them with multi-needle bed computerized flat knitting machines and corresponding needles on their needle beds;

[0021] S3: Based on the weaving process, the flyknit upper is formed by a multi-needle bed computer flat knitting machine, which has several ventilation holes, support strips and air guides.

[0022] S4: The knitted upper is pre-shrinked and shaped to stabilize the structure of the ventilation holes, support strips and air guides. Then the waste edges are trimmed to obtain the finished upper.

[0023] The present invention is further configured such that: the toe dorsal ventilation area is aligned with the shape of the fan-shaped area of ​​the entire toe dorsal protrusion from the tip of each toe to the forefoot, and the spacing between several adjacent ventilation holes in the toe dorsal ventilation area gradually increases from the middle position near the foot to the surrounding area.

[0024] The invention is further configured such that the arch guide area is aligned with the shape of a semi-circular area that spreads from the base of the third toe toward the direction away from the sole of the foot, extending to the space between the first and second toes, and the space between the fourth and fifth toes.

[0025] The present invention is further configured such that the lateral stabilizing zone is located between the toe dorsal ventilation zone and the arch guiding zone.

[0026] In summary, the present invention has the following beneficial effects:

[0027] By integrating multiple needle beds into one piece, a venturi tube structure is formed to create a guide plate that is directionally connected to the ventilation holes, thereby achieving active ventilation by utilizing the arch of the foot during walking and effectively improving the breathability of the flyknit upper.

[0028] The spacing of the ventilation holes in the zoned design ensures efficient heat dissipation while maintaining local support and overall stability of the upper, achieving a balance between breathability and structural stability. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] A breathable flyknit upper, such as Figure 1 , Figure 2 as well as Figure 6 As shown, the flyknit upper includes a breathable surface 1 distributed at the toe position. The breathable surface 1 has several arrayed breathable holes 4. The breathable surface 1 is knitted by a flat knitting machine with three needle beds equipped with knitting needles. The three needle beds are a front bed, a back bed, and an auxiliary bed. The front bed and the back bed knit to form the breathable surface 1 and several support strips 2. The auxiliary bed knits synchronously with the other two needle beds and knits to form several air guides 3.

[0038] The support strips 2 and air guides 3 are both disposed on the breathable surface 1. Several support strips 2 are distributed around the air vents 4, with each end of the support strip pointing towards an adjacent air vent 4. The support strips 2 are recessed into the surface of the breathable surface 1. Several air guides 3 are distributed around the air vents 4, with the middle section of the air guides 3 bulging away from the breathable surface 1. The air guides 3 and support strips 2 are distributed on both sides of the breathable surface 1, that is, the air guides 3 are on the outer side of the knitted upper, and the support strips 2 are on the inner side of the knitted upper. The support strip 2 is set between the back of the toe and the breathable surface 1 to form an air gap, so that the air passing through the vent 4 can be dispersed more quickly, enhancing the heat dissipation effect on the toes. The air guide 3 and the breathable surface 1 surround each other to form a connected air inlet 31 and air outlet 32. The air outlet 32 ​​is set closer to the vent 4 than the air inlet 31. The cross-sectional area of ​​the air guide 3 decreases unidirectionally along the direction from the air inlet 31 to the air outlet 32. The reduction of the channel causes the inner wall of the channel to form a Venturi effect, increasing the wind speed at the air outlet 32.

[0039] In order to enable the high-speed airflow to enter the vent 4 more effectively through the channel, the cross-sectional shape of the vent 4 is stretched towards the interior of the adjacent air outlet 32, so that the airflow can be more easily guided into the vent 4 under the guidance of the shape of the air guide 3. Therefore, the air guide 3 has good gas-collecting performance. For this reason, the yarn density of the air guide 3 is greater than that of the breathable surface 1. In order to make the middle of the shape of the air guide 3 higher, so that the air can enter the channel more easily when the shoe is worn and walked, the breathable surfaces 1 on both sides of the air guide 3 are narrowed towards the middle section.

[0040] like Figures 1 to 4 As shown, this embodiment uses a three-needle bed computerized flat knitting machine. The air guide plate 3 is woven to form a single-sided structure. In order to have a larger cross-sectional area of ​​channels, the breathable surface 1 is woven to form a single-sided structure at the position covered by the air guide plate 3. Considering that the wearer's foot movements during walking will bring up wind in opposite directions during the two steps of extending and lifting, in order to make the channels have a better air guiding effect during the two movements, the breathable surface 1 is symmetrically provided with air inlets 31 and two air guide plates 3 arranged at intervals and facing each other in the smallest area formed by several support strips 2. The two air guide plates 3 have a structure with a large spacing in the middle and a narrow spacing on both sides. Several support strips 2 and air guide plates 3 are evenly distributed around several ventilation holes 4. In order to guide the wind blowing on the outside of the air guide plate 3 to the ventilation holes 4, the two sides of the air guide plate 3 are smoothly connected to the concave positions of the adjacent support strips 2.

[0041] In order to make it easier for a pair of air guide vanes 3 to take in air in a relative state at the middle position of the air inlet 31, the permeable surface 1 between two adjacent air guide vanes 3 is connected to the single-sided structure on both sides by a non-woven form.

[0042] like Figure 1 as well as Figure 2As shown, the support bar 2 has a double-sided structure. Both sides of the support bar 2 are connected to the air-permeable surface 1 and the air guide plate 3 in a loop. This is achieved by forming a ring structure on both the front bed and the rear bed.

[0043] In order to allow the structure of the support strip 2 to be pre-treated before the finishing process of the flyknit upper, the middle part of the support strip 2 is woven with two support yarns of different weights. The support strip 2 has a loop connection with the breathable surface 1 at the end near the ventilation hole 4. The support yarn with a relatively higher weight is woven on the same side as the breathable surface 1 where the air guide 3 is located. The yarns with different weights have different shrinkage rates during the finishing process. This connection structure is specifically achieved by forming loop structures in the front bed and the back bed respectively, and shifting the loops back and forth near the ventilation hole 4. When the length of the ventilation hole 4 along the warp direction increases, the change of the air guide 3 along the warp direction during weaving is reflected in the number of loops formed by the loop structures in the front bed and the back bed respectively.

[0044] like Figure 1 as well as Figure 2 As shown, the breathable surface 1 is woven with several shifting ring structures at the edge position near the breathable hole 4 in a direction away from the breathable hole 4, so as to form a stretching effect on the structure of the breathable hole 4.

[0045] A method for producing breathable flyknit shoe uppers, used to produce the aforementioned flyknit shoe uppers, such as... Figure 5 As shown, it includes the following steps:

[0046] S1: Using a pattern-making program, the breathable surface 1 on the flyknit upper is divided into areas. Based on the spacing of several breathable holes 4 in each area, the positions and structures of support strips 2 and air guides 3 are set in each area to form a weaving program, such as... Figure 6 As shown, S1 sets the spacing between adjacent air vents 4 through the following sub-steps:

[0047] S1.1: Based on the distribution characteristics of the toe contact area of ​​different foot types and the shape of the arch of the foot, the breathable surface 1 is selected and divided into multiple areas, including the toe breathable area 11, the arch guiding area 12 and the side stabilizing area 13.

[0048] S1.2: Different distribution of ventilation holes 4 is adopted for different areas. Several ventilation holes 4 in the dorsal toe ventilation area 11 are radially distributed with gradually increasing spacing. Several ventilation holes 4 in the arch guidance area 12 are densely distributed with the same spacing. Several ventilation holes 4 in the lateral stability area 13 are sparsely distributed with the same spacing.

[0049] like Figure 6As shown, the toe ventilation area 11 is aligned with the shape of the fan-shaped area of ​​the entire toe dorsum protruding from the tip of each toe to the forefoot. The spacing between several adjacent ventilation holes 4 in the toe ventilation area 11 gradually increases from the middle position near the foot to the surrounding area. The arch guide area 12 is aligned with the shape of the semi-circular area that spreads from the base of the third toe in the direction away from the foot. Its range extends to the gap between the first and second toes and the gap between the fourth and fifth toes. The side stabilization area 13 is located between the toe ventilation area 11 and the arch guide area 12.

[0050] The toes are the area with the most frequent bending, the most friction, and the most concentrated sweat glands. The fan-shaped area of ​​the toe ventilation zone 11 perfectly covers this area. The dense holes provide better extensibility and flexibility for the complex deformation of this area. The layout that transitions from dense to sparse ensures breathability while also ensuring a smooth transition in structural strength. The arch guide zone 12 is the area where the muscles and fascia undulate most significantly during arch movement. When the arch expands, the internal volume of the shoe upper increases, creating a negative pressure effect. External air can be efficiently drawn in through the ventilation holes 4. When the arch contracts, it compresses the air inside the shoe upper, allowing the air in this area to be efficiently discharged through the ventilation holes 4. The side stability zone 13 is set up to share the structural pressure with the toe ventilation zone 11 and the arch guide zone 12, improving the structural stability between the yarns in the flyknit upper.

[0051] When making the board, first divide the main area of ​​the breathable surface 1, then divide the toe dorsum breathable area 11 and the arch guide area 12 in sequence, and divide the remaining main area into the side stability area 13.

[0052] Then, based on the distribution pattern of the ventilation holes 4 in each area, the program generates the loop shifting instructions for forming the ventilation holes 4. According to the direction of the support strip 2 and the raised contour of the air guide 3, the knitting symbols and yarn feeder paths on the front bed, back bed and auxiliary bed are defined respectively to ensure that the three can be knitted synchronously. For two symmetrically set opposite air guides 3, the board making program programs the air surface 1 position between them as an empty needle area to achieve non-woven connection.

[0053] S2: Select yarns with different counts and properties to knit the breathable surface 1, support strip 2 and air guide plate 3 respectively, and equip them with a multi-needle bed computerized flat knitting machine and the corresponding knitting needles on its needle bed.

[0054] In this embodiment, 40S cotton-nylon blended yarn is selected as the weaving yarn for the breathable surface 1; 300D low-elastic yarn and 150D high-elastic yarn are selected as the two support yarns for the support strip 2. The 300D low-elastic yarn is arranged on the back bed on the same side as the air guide plate 3 for weaving. 20S high-count and high-strength polyester yarn is selected as the weaving yarn for the air guide plate 3 to achieve its higher yarn count density requirement. The above yarns are installed to the corresponding yarn nozzles, and the knitting needle positions of the front bed, back bed and auxiliary bed are calibrated.

[0055] S3: Based on the weaving process, the flyknit upper is formed by integrated weaving of a multi-needle bed computer flat knitting machine, which has several ventilation holes 4, support strips 2 and air guide plates 3.

[0056] In this embodiment, through the coordinated knitting of multiple needle beds, the needles of the front and rear beds work together through specific loop-forming, loop-gathering and loop-shifting actions to simultaneously knit a support strip 2 with a double-sided structure and a breathable surface 1 as a base. At the positions set by the program, breathable holes 4 are formed by shifting loops. The two types of yarns with different weights and shrinkage characteristics used in the support strip 2 are knitted into predetermined positions in this process, providing a basis for subsequent heat shrinking and setting.

[0057] At the same time, the auxiliary bed participates in the knitting, constructing the air guide plate 3 through a single-sided structure, and controlling the air guide plate 3 through processes such as needle reduction, so that the breathable surface 1 fabric on both sides of the air guide plate 3 is gathered towards it, thereby naturally shaping a structure with a raised middle section and a continuous and smooth channel. All structures are completed in one step on the flat knitting machine, ensuring the integrity and connection reliability of the overall flyknit upper.

[0058] S4: The flyknit upper is pre-shrinked and shaped to stabilize the structure of the ventilation holes 4, support strips 2 and air guides 3. Then the waste edges are trimmed to obtain the finished upper.

[0059] In this embodiment, the yarns of different weights inside the support strip 2 shrink differently due to the heat shrinkage rate. The yarns with higher weights generate greater shrinkage force, thereby actively pulling the structure of the support strip 2 to produce the expected concave deformation, and further stabilizing the channel structure of the adjacent air guide 3. After heat treatment, the shoe upper is cooled and shaped, and then the waste edge of the bottom is removed by the cutting process, retaining the complete functional area, and finally obtaining a structurally stable finished flyknit shoe upper.
