[0021] Example

[0022] This embodiment specifically includes the following steps: First, an outer layer 2 and an inner layer 4 are woven together using a circular knitting machine. The outer layer 2 is made of polyester filament material, and the inner layer 4 is made of a blended yarn of nylon and spandex. A stepped decrease in stitches is performed in the collar area to form a U-shaped ankle curve 3. A covering space with a thickness of approximately 1.5 mm is naturally formed between the outer layer 2 and the inner layer 4. A filling layer is placed within this covering space. The filling layer is made of sponge material and has a thickness of 3.0 mm, which is greater than the thickness of the covering space. A water-based adhesive is used to bond the filling layer. The layer is fixed between the outer layer 2 and the inner layer 4. The combined material is fixed to the 5D hot press mold through the hanging nail holes. The mold temperature is set to 160℃ for hot pressing treatment, and the hot pressing time is 120 seconds. After the treatment is completed, the product is removed after cooling. Finally, the excess material is cut off according to the marked lines to obtain the finished shoe heel component. The thickest part of the top of the component is 3.5mm thick, and the thickest part of the bottom is 2.0mm thick. The thickness decreases from the periphery of the ankle to the center (3.0mm periphery → 1.5mm center), and the whole presents an S-shaped vertical cross section.

[0023] Example

[0024] The specific implementation method of this embodiment is as follows: An outer layer 2 and an inner layer 4 are formed using an integrated weaving process. The outer layer 2 area uses polyester yarn and TPU filament for multi-color weaving, while the inner layer 4 area uses high-elastic yarn containing spandex woven in a plain weft stitch. A stepped stitch variation is performed in the ankle curve 3 area, specifically including a decrease stage (reducing 3 stitches every 2 rows, repeated 5 times) and an increase stage (increasing 4 stitches every 2 rows, repeated 5 times), forming a U-shaped outline. A 1.8mm thick covering space is set between the outer layer 2 and the inner layer 4. This covering space is filled with a composite layer of a shaped support piece and sponge, with the support piece being 0.8mm thick. The sponge layer is 2.5mm thick, and the total filling thickness is 3.3mm, which is greater than the thickness of the covering space. Water-based adhesive is applied by machine spraying for fixation. Hanging nail holes are formed on the material using laser equipment. After the material is hung on a 5D hot press mold, the upper mold temperature is set to 155℃ and the lower mold temperature to 140℃ for 100 seconds of hot pressing. In the finished product, the thickest part of the shoe heel body 1 at the top is 3.8mm and the thickest part at the bottom is 2.2mm. The thickness distribution shows a continuous decrease from 3.2mm at the side point to 2.1mm at the 45° position and then to 1.6mm at the center point. The whole has an S-shaped vertical cross section.

[0025] Example

[0026] This embodiment specifically includes the implementation of three knitting areas: Area 1 (inner heel lining) is knitted with nylon yarn using a plain weft stitch, with a loop length of 3.0mm; Area 2 (U-shaped neckline) uses a stepped stitch method, specifically starting with 72 stitches in the first row, decreasing to 60 stitches in rows 1-5, and increasing to 75 stitches in rows 6-10; Area 3 (outer heel surface) is knitted with polyester filament using a jacquard stitch, forming a 1.8mm thick covering space between the outer layer 2 and the inner layer 4. A 3.2mm thick sponge filling layer is placed within the covering space. Before hot pressing, the fabric is steam-ironed at 100℃ (the pin hole spacing of the 5D hot pressing mold is set to 5mm), and the hot pressing parameters are set to 150℃ for 90 seconds. The final product thickness distribution is 3.6mm at the upper edge of the ankle, 2.4mm at the Achilles tendon contact area, and 1.9mm at the heel weight-bearing area, forming an overall S-shaped vertical cross-section.

[0027] Example

[0028] Step 1 of this embodiment: Design a multi-color heel pattern and establish a product code. Step 2: Convert the design pattern into a circular knitting program for the circular knitting machine, wherein the ankle curve area 3 uses a stepped stitch programming method. Step 3: Select nylon yarn for the inner layer 4 and polyester yarn for the outer layer 2. Step 4: Thread the yarn into the circular knitting machine nozzle according to the process requirements. Step 5: Perform 100℃ steam ironing on the woven fabric. Step 6: Stack four layers of sponge material and then cut them. Step 7: Apply a coating to the fabric using a spraying method. Water-based adhesive is applied evenly to outer layer 2 and inner layer 4. Step 8: Use laser equipment to form hanging holes on the fabric. Step 9: Install the 5D hot press mold and set the temperature parameters. Step 10: Hang the material on the mold for hot pressing and shaping. Step 11: Use an edge trimmer to cut off the excess material along the marking line formed by hot pressing. The thickness of the basic covering space is 1.6mm, the total thickness of the filling layer is 3.0mm (including sponge and backrest), the radius of the ankle curve 3 is 16mm, the thickness of the thickest area at the top is 3.7mm, and the thickness of the thickest area at the bottom is 2.1mm.

[0029] Example

[0030] In this embodiment, the heel body 1 is formed by a circular knitting machine to create an inner layer 4 and an outer layer 2, with a 1.5mm thick covering space between them. A filling layer with a thickness of 3.0mm is placed in this space, which is greater than the thickness of the covering space. The ankle curve 3 area is formed into a U-shaped neckline structure by a stepped decrease operation (rows 1-10) and a stepped increase operation (rows 11-20). The thickest part of the top of the heel body 1 is 3.8mm thick, and the thickest part of the bottom is 2.0mm thick. The thickness distribution decreases continuously from 3.2mm around the ankle to 1.5mm in the central area, presenting an overall S-shaped vertical cross-section. The filling layer is fixed with a water-based adhesive. The outer layer 2 is made of polyester and nylon, and the inner layer 4 is made of spandex.

[0031] Example

[0032] The manufacturing method of this embodiment is as follows: The outer layer 2 (polyester filament) and the inner layer 4 (nylon and spandex blended yarn) are woven together by a circular knitting machine. A U-shaped ankle curve 3 is formed in the collar area by step-by-step stitch reduction (the number of stitches in the first row is higher than that in the second row). A 1.5mm thick covering space is formed between the outer layer 2 and the inner layer 4. A 3.0mm thick sponge filling layer is built in (the second thickness is greater than the first thickness). The sponge is bonded to the outer layer 2 and the inner layer 4 using water-based adhesive. The material is fixed to a 5D hot press mold through laser-made pin holes. The temperature is set to 160℃ and the hot press time is 120 seconds. After cooling, the excess material is trimmed. The thickest part at the top of the finished product is 3.5mm, and the thickest part at the bottom is 2.0mm. The thickness decreases from 3.0mm around the ankle to 1.5mm in the center. The overall shape is an "S" shaped vertical cross section.

[0033] Example

[0034] This embodiment employs an integrated weaving process to form the outer layer 2 and inner layer 4. The outer layer 2 is woven with polyester yarn and TPU filament in multiple colors, while the inner layer 4 is woven with high-elastic yarn containing spandex using a plain weft stitch. The ankle curve 3 area is formed through a stepped stitch variation: during the decrease stage, 3 stitches are reduced every 2 rows (repeated 5 times), and during the increase stage, 4 stitches are increased every 2 rows (repeated 5 times), forming a U-shaped outline. A 1.8mm thick covering space is set between the outer layer 2 and the inner layer 4, filled with a composite layer of a 0.8mm shaping backrest sheet and a 2.5mm sponge (total thickness 3.3mm). The filling layer is fixed by machine spraying water-based adhesive, and hanging pin holes are laser-made. The material is then mounted on a 5D hot press mold, with the upper mold temperature set to 155℃ and the lower mold temperature to 140℃, and hot-pressed for 100 seconds. The thickest part at the top of the finished product is 3.8mm, and the thickest part at the bottom is 2.2mm, with the thickness increasing from 3.2mm on the side. The thickness decreases continuously by 1.6mm towards the center point, forming an overall "S"-shaped vertical cross-section.

[0035] Example

[0036] This embodiment employs a regionally differentiated knitting design: Region 1 (inner heel lining) is knitted with nylon yarn using a plain weft stitch (loop length 3.0mm); Region 2 (U-shaped neckline) starts with 72 stitches, decreases to 60 stitches in rows 1-5, and increases to 75 stitches in rows 6-10, forming ankle curve 3; Region 3 (outer heel layer) is knitted with polyester filament using a jacquard stitch, creating a 1.8mm thick covering space between outer layer 2 and inner layer 4, with a 3.2mm thick sponge filling layer inside. Before hot pressing, it is steam-ironed at 100℃, with a pin hole spacing of 5mm, and hot pressing parameters of 150℃ for 90 seconds. The finished ankle upper edge is 3.6mm, the Achilles tendon contact area is 2.4mm, and the heel weight-bearing area is 1.9mm, with an overall "S" shaped vertical cross-section.

[0037] Example

[0038] This embodiment designs a multi-color heel drawing and converts it into a circular knitting program (ankle curve 3 uses a stepped stitch programming method). The inner layer 4 is made of nylon yarn, and the outer layer 2 is made of polyester yarn. The fabric is woven on a circular knitting machine and then steam-ironed at 100°C. The sponge material is stacked in 4 layers and then cut. Water-based adhesive is sprayed onto the sponge and bonded to the fabric. Hanging pin holes are made by laser and the fabric is fixed to a 5D hot press mold. After hot pressing and shaping, the excess material is cut off along the marking line. The finished product has a coverage space of 1.6mm, a filling layer of 3.0mm (including sponge and heel counter), an ankle curve 3 radius of 16mm, a top maximum thickness of 3.7mm, and a bottom maximum thickness of 2.1mm.

[0039] Example

[0040] In this embodiment, the inner layer 4 and outer layer 2 of the shoe heel body 1 are woven together to form a 1.5mm thick covering space. The inner layer is 3.0mm thick and contains a filling layer (including sponge and a shaping backrest). The ankle curve 3 is formed into a U shape by decreasing stitches from row 1 to 10 and increasing stitches from row 11 to 20. The thickest part of the top of the shoe heel is 3.8mm and the thickest part of the bottom is 2.0mm. The thickness decreases from 3.2mm around the ankle to 1.5mm in the center, forming an "S" shaped cross section. The filling layer is fixed with water-based adhesive. The outer layer 2 contains polyester and nylon, and the inner layer 4 contains spandex.

[0041] Example

[0042] The specific process steps for this implementation are as follows: Step 1: Design the follow-up drawing with multi-color effects, establish product name codes according to standards, and clarify the product design line size standards and usage functional requirements; Step 2: Convert the design drawings into weaving procedures and weaving process standards for weft knitting equipment according to the requirements of documents and standards, and simultaneously customize the hot pressing mold and convert the film paper according to the above standards; Step 3: Select yarn raw materials, filling materials, and shaping accessories that meet the production conditions and physical and chemical properties according to the standard requirements of Step 1; Step 4: Import the weaving process program into the weaving equipment, thread the prepared yarn into the yarn feeder in sequence according to the weaving process standard, and start weaving after the equipment is adjusted to ensure there are no abnormalities. Step 5: After the fabric is woven, it is cut into a flat surface by a tubular structure (circular knitting machine), and then steam ironed at 100 degrees Celsius. For fabrics that do not use hot melt yarn, the high-temperature treatment is to allow the fabric to shrink fully under heat to achieve the desired fabric effect. For fabrics that use hot melt yarn, the high-temperature treatment is required to melt the hot melt yarn and bond it into the fabric to achieve the desired fabric effect. Step 6: Stack the whole roll of sponge material into 4 layers, lay the stacked sponge material flat on the punch press table, set the punch press pressure, and cut the whole roll of material into the set size. Step 7: Spray water-based glue evenly onto the sponge filling and the inside and outside of the fabric, then smoothly bond the inside and outside of the fabric to the sponge, ensuring that the bonding area is flat, smooth and wrinkle-free. Step 8: Convert the positioning points on the film drawing into a file format that the laser equipment can read, set the laser machine's operating speed, power and other parameters, then attach the film drawing to the laser table for fabric alignment, lay the woven fabric flat on the laser table, and start the laser hanging pin hole. Step 9: Place the hot pressing mold flat on the operating table of the molding machine according to the alignment slot functional area, tighten the upper and lower fixing screws, ensure that the mold is installed without deviation and the hanging nails are not deformed, set the function parameters of the molding machine according to the material properties and functional requirements, and start heating; Step 10: Hang the materials into the nail holes in the order of the design, start the equipment to heat and stabilize the shape, set the spacing between the middle of the shaping support frame to 5CM, take out the stabilized product and put it into the shaping support frame until the product cools down; Step 11: After the product has cooled, use an edge trimming machine to trim off the excess edges along the marked lines after the shape has been stabilized. The product is now complete.
