Description

Technical Field

[0001] This invention relates to the field of shoe heel knitting technology, and in particular to a foldable and wrap-around flyknit shoe heel knitting method and the shoe heel thereof. Background Technology

[0002] To enhance overall stability and support, conventional footwear typically incorporates heel supports. Traditional heel supports are often made of foam and structural components. These parts are attached to the heel against the foot using processes like heat pressing. Each layer requires heat pressing, and after repeated exposure to the high temperatures of these processes, the foam material is prone to deformation and cracking. Furthermore, the fabric covering the foam is inherently weak and easily breaks down due to prolonged friction with the foot, reducing shoe comfort and lifespan. Additionally, the diverse and complex materials used in heel supports create environmental challenges related to recycling. Summary of the Invention

[0003] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a foldable and coverable flyknit shoe heel weaving method and shoe heel. By forming a single-layer fabric with multiple rows of knitting through turning needles between the double-layer bearing surface and the covering surface, positioning lines are formed, so that the entire fabric has obvious pattern and thickness changes at the folding point, which is convenient for workers to identify and fold. The folded fabric can cover the support component. At the same time, an integrally woven solid raised structure is set on the shoe heel, which replaces the built-in sponge in the conventional shoe heel. Compared with the traditional method of repeatedly hot-pressing to form the finished shoe heel, the above process can reduce the processing steps. After the knitted fabric is folded, the pre-hot-pressed finished support component is filled in, avoiding the process of repeatedly hot-pressing the support component and sponge into the shoe heel in the traditional shoe heel processing, thereby reducing the damage of hot pressing to the sponge and fabric and improving wear resistance.

[0005] This invention provides a method for weaving a foldable, covered flyknit shoe heel and the shoe heel thereof, including...

[0006] S1. Knit the support surface on one side of the heel of the shoe. This support surface is a double-layer structure. When knitting to the collar, the undulating outline of the collar is created by decreasing stitches in a step manner.

[0007] S2. After the collar outline on the receiving surface is knitted, turn the stitches on one side of the needle bed to the other side of the needle bed to form a single layer. Knit several rows of single-sided stitches on the single layer after turning the stitches for folding, and then continue to knit the comb-up structure and the cylindrical structure.

[0008] S3. Using a step increase stitch method, knit the shoe collar outline on the other side of the shoe heel cover surface. Knit a cylindrical structure in part of the shoe collar outline and knit multiple rows of hanging stitches inside to form a raised structure.

[0009] S4. Continue weaving the covering on the other side of the heel to form the entire heel. The covering is a double-layered structure.

[0010] In some embodiments, in step S3, the more rows of stitches woven, the higher the protrusion. The support layer is woven using the stitch method, and the more rows of stitches woven, the higher the protrusion. With the help of the padding yarn process, a solid protrusion can be formed, which plays the role of the sponge in the traditional shoe heel. With the help of the solid protrusion, the amount of material required to produce the entire shoe heel is reduced, the composition is simple, and it is conducive to environmental protection and recycling.

[0011] In some embodiments, the raised structure includes a top layer, a support layer, and a bottom layer, the top layer and the bottom layer corresponding to the double-layer structure of the receiving surface, and the top layer and the bottom layer corresponding to the double-layer structure of the covering surface. The support layer is separately protruded by a hook-and-eye weave, thereby forming the support layer.

[0012] In some embodiments, the support layer is the multi-row heel tab, and the upper and lower edges of the raised tissue are both arc-shaped. The arc-shaped edges are designed to reduce friction with the user's skin and decrease the occurrence of abrasions and chafing on the heel.

[0013] In some embodiments, in step S2, the comb-up structure is a four-line knit, which is a knitting technique used when starting with an empty needle or transitioning from a single-layer structure to a double-layer structure. Both the bearing surface and the covering surface are double-layer structures, while the abrasion-resistant area knitted in step S2 for folding is a single-layer structure. Four-line knit is required during the transition between the three.

[0014] In some embodiments, the cylindrical structure is a double-layer weave, that is, a double-layer weave corresponding to the top layer, the bottom layer, and the receiving surface of the raised structure. Except for the abrasion-resistant area and the raised structure, the remaining areas requiring double-layer weaving are collectively referred to as the cylindrical structure. Flyknit fabric has the advantages of being lightweight, breathable, and having better fit and breathability. Increasing the number of weave layers on the basis of flyknit fabric improves its abrasion resistance, making it suitable for shoe heel production.

[0015] A foldable, wrap-around flyknit shoe heel includes a support surface, a cover surface connected to the support surface, and a support member located between the support surface and the cover surface. The cover surface is provided with a raised structure, which is integrally woven with the cover surface. The cover surface is in contact with the support surface, and the upper side of the support member extends upward to the raised structure. The interlocking support and cover surfaces form the main shape of the shoe heel. The raised structure replaces the built-in sponge on conventional shoe heels, serving to conform to the shape of the heel. The raised structure, woven together with the cover surface, maintains good integrity while reducing the need for manual sponge filling. The support component inserted between the cover surface and the support surface provides support. Extending upwards to the raised structure, the combined thickness of the raised structure and support component can reach the same thickness as a conventional shoe heel. Compared to the conventional method of heat-pressing the support component on one side of the shoe heel, the method of wrapping and clamping the support component saves on manual production steps and avoids repeated heat pressing, which can damage the shape and durability of the shoe heel.

[0016] In some embodiments, both the covering surface and the receiving surface have abrasion-resistant areas on their upper sides, and the raised tissue is located within the abrasion-resistant area of ​​the covering surface. An abrasion-resistant area is added to the contact friction point between the heel and the foot, making the contact area more abrasion-resistant and extending the lifespan of the shoe.

[0017] In some embodiments, a positioning line is provided on the abrasion-resistant area, and the positioning line is a single-layer knitted structure. The single-layer knitted fabric is dense and thick, with low lateral elongation and dimensional stability. When both the covering and receiving surfaces are double-layered, the single-layer abrasion-resistant area is easy to fold and makes it easy for workers to identify the fold position during processing. When the surface is folded, the covering and receiving surfaces are of different sizes.

[0018] In some embodiments, the covering surface and the receiving surface are incorporating heat-setting materials, and the side of the covering surface in contact with the receiving surface is woven with thermoplastic polyurethane elastomer. Common heat-setting materials include hot melt yarn and TPU polyester fiber. After the common fabric is woven, it needs to undergo high-temperature treatment. For fabrics using hot melt yarn, high-temperature treatment is required to melt and bond the hot melt yarn into the fabric, achieving a stiff and supportive effect. For fabrics not using hot melt yarn, high-temperature treatment is to allow the fabric to shrink sufficiently under heat to achieve a suitable fabric effect. The side of the covering surface in contact with the receiving surface is woven with TPU-like polyester fiber material. Without inserting support materials such as heel counters, it can be directly hot-pressed through a mold to provide excellent support. The heel can also be woven integrally with the shoe body, with the same material and pattern, creating a natural transition and a consistent texture effect with the shoe body, making the overall shoe more harmonious and beautiful.

[0019] By adopting the above technical solution, the beneficial effects of the present invention are:

[0020] This invention creates a single-layer fabric with multiple rows of knitting between a double-layered support surface and a covering surface, forming positioning lines. This results in a clear pattern and thickness variation at the folding points, facilitating worker identification and folding. The folded fabric can then enclose the support component. Simultaneously, an integrally woven solid raised structure is incorporated into the heel, replacing the traditional built-in sponge in shoe heels. Compared to the traditional method of repeatedly hot-pressing to form the finished shoe heel, this process reduces processing steps. After the knitted fabric is folded, the pre-hot-pressed support component is inserted, avoiding the traditional process of repeatedly hot-pressing the support component and sponge into the heel. This reduces damage to the sponge and fabric caused by hot pressing and improves wear resistance.

[0041] According to some embodiments of the present invention, the present invention provides a method for weaving a foldable, covered flyknit shoe heel and the shoe heel thereof, including...

[0042] S1. The supporting surface 1 on one side of the heel of the shoe is double-layered. When knitting to the collar, the undulating outline of the collar is created by decreasing stitches in a step manner.

[0043] S2. After the shoe collar outline on the receiving surface 1 is knitted, turn the stitches on one side of the needle bed to the other side of the needle bed to form a single layer of structure. Knit several rows of single-sided stitches on the single layer of structure after turning the stitches for folding, and then continue to knit the comb structure and the cylindrical structure.

[0044] In step S2, the comb-up structure is a four-line knit, which is a knitting technique used when starting with an empty needle or transitioning from a single-layer structure to a double-layer structure. Both the bearing surface and the covering surface 2 are double-layer structures, while the abrasion-resistant area 4 knitted in step S2 for folding is a single-layer structure. Four-line knit is required during the transition between the three.

[0045] The cylindrical structure is a double-layer weave, that is, the double-layer weave of the top layer, the bottom layer, and the supporting surface 1 corresponding to the raised structure 3. Except for the wear-resistant area 4 and the raised structure 3, the remaining areas that require double-layer weaving are collectively referred to as the cylindrical structure. Flyknitted fabric has the advantages of being lightweight, breathable, and having better fit and breathability. Increasing the number of weave layers on the basis of flyknitted fabric improves its wear resistance, making it suitable for shoe heel production.

[0046] S3. Using a step-increasing stitch method, knit the shoe collar outline on the other side of the shoe heel cover surface, knit a cylindrical structure in a part of the shoe collar outline and knit multiple rows of hanging stitches inside to form raised structure 3;

[0047] The raised structure 3 includes a surface layer, a support layer, and a bottom layer. The surface layer and the bottom layer correspond to the double-layer structure of the receiving surface 1, and the surface layer and the bottom layer correspond to the double-layer structure of the covering surface 2. The support layer is protruded separately by a hanging mesh weave, thereby forming a support layer.

[0048] The support layer consists of multiple rows of weave stitches. The upper and lower edges of the raised structure 3 are both curved. The more rows of weave stitches, the higher the protrusion. The support layer is woven using a weave stitch method. The more rows of weave stitches, the higher the protrusion. With the addition of padding yarn, a solid protrusion can be formed, which plays the role of a sponge in the traditional shoe heel. With the help of the solid protrusion, the amount of material required to produce the overall shoe heel is reduced, the composition is simpler, and it is conducive to environmental protection and recycling. The curved edge is designed to reduce friction with the user's skin and reduce the occurrence of heel abrasion and chafing.

[0049] S4. Continue weaving the covering on the other side of the heel to form the entire heel. The covering is a double-layered structure. Both the supporting surface 1 and the covering surface 2 are knitted using flyknit.

[0050] Reference Figure 5-7 , Figure 5 This is a schematic diagram of the unfolded structure of the covering surface and the receiving surface in some embodiments of the present invention. Figure 6 This is a schematic diagram of the combined structure of the covering surface and the receiving surface in some embodiments of the present invention; Figure 7 This is a schematic diagram of the overall structure of the shoe heel in some embodiments of the present invention.

[0051] The present invention also includes a foldable and coverable flyknit shoe heel, comprising a receiving surface 1, a covering surface 2 connected to the receiving surface 1, and a support member 5 located between the receiving surface 1 and the covering surface 2. The covering surface 2 is provided with a raised structure 3, which is integrally woven with the covering surface 2. The covering surface 2 is attached to the receiving surface 1, and the upper side of the support member 5 extends upward to the raised structure 3. The mutually fitting support surface 1 and cover surface 2 constitute the main shape of the shoe heel. The raised tissue 3 replaces the built-in sponge on the conventional shoe heel, and plays a role in conforming to the shape of the heel. The raised tissue 3, woven together with the cover surface 2, can maintain good integrity and reduce the steps of manually filling the sponge tissue. The support member 5, filled between the cover surface 2 and the support surface 1, plays a supporting role. After extending upward to the raised tissue 3, the thickness of the raised tissue 3 and the support member 5 combined can reach the same thickness as the conventional shoe heel. Compared with the conventional method of hot-pressing the support member 5 on one side of the shoe heel, the method of wrapping and clamping the support member 5 can save more manual production steps and avoid repeated hot pressing, which would damage the shape and durability of the shoe heel.

[0052] According to some embodiments of the present invention, optionally, both the covering surface 2 and the receiving surface 1 are provided with abrasion-resistant areas 4, and the raised tissue 3 is located within the abrasion-resistant area 4 of the covering surface 2. The abrasion-resistant area 4 is added to the contact friction position between the heel and the foot, making the contact area more abrasion-resistant and extending the service life of the shoe.

[0053] The wear-resistant area 4 is equipped with a positioning line, which is a single-layer knitted structure. The single-layer knitted fabric is dense and thick, with less lateral stretch and stable dimensions. With both the covering surface 2 and the receiving surface 1 being double-layered, the single-layer wear-resistant area 4 facilitates folding and makes it easy for workers to identify the fold position during processing. When the surface is folded, the covering surface 2 and the receiving surface 1 are different sizes.

[0054] The covering surface 2 and the receiving surface 1 are incorporating heat-setting materials. The side of the covering surface 2 that contacts the receiving surface 1 is woven with thermoplastic polyurethane elastomer. Common heat-setting materials include hot melt yarn and TPU polyester fiber. After the common fabric is woven, it needs to undergo high-temperature treatment. For fabrics using hot melt yarn, high-temperature treatment is required to melt and bond the hot melt yarn into the fabric, achieving stiffness and support. For fabrics not using hot melt yarn, high-temperature treatment is to allow the fabric to shrink fully under heat, achieving the appropriate fabric effect. The side of the covering surface that contacts the receiving surface is woven with TPU-like polyester fiber material. Without inserting support materials such as heel counters, it can be directly hot-pressed through a mold, which can also provide excellent support. The heel of the shoe can also be woven integrally with the shoe body, with the same material and pattern, resulting in a natural transition and creating a consistent texture effect with the shoe body, making the overall shoe more harmonious and beautiful.
