Description

Technical Field

[0001] This invention relates to a method for manufacturing shoe uppers. Background Technology

[0002] Most shoes consist of an upper and a sole. The upper is attached to the sole, and the two together form a space for the foot to fit over itself. The upper covers the foot and secures it firmly to the sole. The sole is located beneath the foot and supports the body weight.

[0003] Currently, most shoe uppers are made of plastic or fabric and are mostly flat. When patterns are printed onto traditional shoe uppers, the patterns can only present a flat effect and cannot create a three-dimensional effect.

[0004] On the other hand, the typical method of making shoe uppers involves spraying the colored side of the plastic or fabric all over, and then cutting the fully colored plastic or fabric according to the shoe upper pattern to obtain the desired upper. However, this method of making shoe uppers cannot produce small-batch, diverse products that allow for individual creativity, and it also results in the waste of colorant and makes it difficult to recycle the colored cutting scraps, leading to an increase in waste.

[0005] This shows that existing shoe upper manufacturing methods still need to be improved in order to address the many problems existing in traditional shoe upper manufacturing methods. Summary of the Invention

[0006] In view of this, the object of the present invention is to provide a shoe upper manufacturing method that enables small-batch, diverse production of products that allow for individual creative expression, avoids waste of pigments, and facilitates the recycling of cutting scraps, thereby reducing waste. Furthermore, the shoe uppers manufactured by the shoe upper manufacturing method provided by the present invention can optionally exhibit a three-dimensional pattern effect.

[0007] To achieve the above objectives, the present invention provides a method for manufacturing a shoe upper, comprising: providing a shoe upper fabric having a planar thermal shrinkage coefficient; placing a heat transfer material on the shoe upper fabric, wherein the heat transfer material is used to print a designed pattern onto heat-transferable paper in a single-sheet output manner using a printer filled with heat transfer dye ink, as a transfer pattern; the heat transfer material has multiple transfer pattern areas and a blank area adjacent to the multiple transfer pattern areas, the multiple transfer pattern areas... The process includes multiple transfer patterns, with the blank area free of these patterns; the outlines of the multiple transfer patterns are substantially the same as the outline of a shoe upper component pattern; the transfer patterns of the heat transfer material are transferred to the shoe upper fabric by the vaporization and penetration of the heat transfer dye, and the transfer patterns and the shoe upper fabric are formed to have a size substantially the same as the shoe upper component pattern according to the planar thermal expansion coefficient of the shoe upper fabric; and the shoe upper fabric with the transfer patterns is precisely cut according to the shoe upper component pattern.

[0008] The advantages of this invention are that the shoe upper manufacturing method provided by this invention allows for small-batch, diverse production of products that allow for individual creativity. A transfer pattern with the same outline as a shoe upper pattern is transferred to the shoe upper fabric through the vaporization and penetration of heat transfer dye, increasing the adhesion of the transfer pattern. Then, based on the planar thermal shrinkage rate of the shoe upper fabric, the transfer pattern and the shoe upper fabric are formed to have approximately the same dimensions as the shoe upper component pattern. Next, the shoe upper fabric with the transfer pattern is cut according to the shoe upper pattern, thereby avoiding dye waste and making the cutting scraps easy to recycle, reducing waste. Furthermore, the shoe uppers manufactured by the shoe upper manufacturing method provided by this invention can optionally achieve a three-dimensional effect from a planar pattern.

[0022] Figure 6 This is a flowchart illustrating a preferred embodiment of a shoe upper manufacturing method according to the present invention. Please refer to it as well. Figures 1 to 6 ,in Figure 6 This is a flowchart illustrating a preferred embodiment of a shoe upper manufacturing method according to the present invention. The shoe upper manufacturing method includes: Step 601, providing shoe upper fabric 2, wherein shoe upper fabric 2 has a planar thermal stretch coefficient; Step 602, place the heat transfer material 1 onto the shoe upper fabric 2, wherein the heat transfer material 1 is as follows: Figure 1 Heat transfer material 1A to Figure 5 Any one of the heat transfer materials 1E; Step 603: The transfer pattern of the heat transfer material 1 is transferred to the shoe upper fabric 2, and according to the planar thermal shrinkage rate of the shoe upper fabric 2, the transfer pattern and the shoe upper fabric 2 are formed to have the same size as the shoe upper component pattern. Step 604: Cut the upper fabric 2 with the transfer pattern according to the upper component pattern; Step 605: Sew the cut upper fabric 2 with the transfer pattern into a three-dimensional upper.

[0023] In this embodiment of the invention, the heat transfer material 1 is printed on heat transferable paper using a printer filled with heat transfer dye ink, in a single-sheet output manner, to form a transfer pattern.

[0024] It is worth mentioning that the hot-pressing time in the above-mentioned shoe upper manufacturing method is between 5 seconds and 100 seconds; the hot-pressing pressure is between 1.5 kg / cm² and 4 kg / cm²; and the hot-pressing temperature is between 60℃ and 200℃ to prevent the shoe upper fabric 2 or heat transfer material 1 from melting due to overheating. In this embodiment of the invention, the melting point of the shoe upper fabric is greater than or equal to 100℃, so the hot-pressing temperature needs to be maintained at 95℃.

[0025] In this embodiment of the invention, the size of the transfer pattern area of ​​the heat transfer material 1 in step 602 is different from the size of the shoe upper component pattern. Specifically, the size of the transfer pattern area of ​​the heat transfer material 1 is enlarged or reduced proportionally to the planar thermal shrinkage rate of the shoe upper fabric 2, so that the shoe upper fabric 2 with the transfer pattern after heat transfer has the same size as the shoe upper component pattern. For example, if the planar thermal shrinkage rate of the shoe upper fabric 2 is 5%, then the size of the transfer pattern area of ​​the heat transfer material 1 needs to be enlarged to approximately 105% of the size of the shoe upper component pattern. Therefore, when a transfer pattern with a size of 105% of the size of the shoe upper component pattern is heat-transferred to the shoe upper fabric 2 with a planar thermal shrinkage rate of 5%, the shoe upper fabric 2 with the transfer pattern after heat shrinkage can have the same size as the shoe upper component pattern.

[0026] In this embodiment of the invention, the upper fabric 2 includes a knitted fabric, an elastic warp and weft fabric, a four-way stretch fabric, or a combination thereof, and the planar thermal shrinkage rate of the upper fabric is 0.5% to 12%. In this embodiment of the invention, the planar thermal shrinkage rate of the upper fabric includes a lateral shrinkage rate, and the lateral shrinkage rate is 0.5% to 12%. In this embodiment of the invention, the planar thermal shrinkage rate of the upper fabric includes a longitudinal shrinkage rate, and the longitudinal shrinkage rate is 0.5% to 12%.

[0027] In this embodiment of the invention, when the upper fabric 2 is a simple knitted fabric, its transverse and longitudinal stretch rates are approximately between 4% and 10%, depending on the yarn material and weaving method. When the upper fabric 2 is a four-way elastic warp and weft fabric woven from rubber filaments wound radially with polyester filaments, and then using these filaments as warp or weft yarns, its transverse stretch rate is approximately between 1% and 5%, and its longitudinal stretch rate is approximately between 2% and 9%, depending on the yarn material and weaving method. When the upper fabric 2 is a four-way stretch fabric that is woven and then bonded to a thermoplastic polyurethane (TPU) film, its transverse and longitudinal stretch rates are approximately between 1% and 3%, depending on the yarn material and weaving method.

[0028] In this embodiment of the invention, step 603, which involves transferring the transfer pattern of the heat transfer material 1 onto the shoe upper fabric, involves causing at least one dye constituting the transfer pattern to penetrate into the shoe upper fabric. In this embodiment of the invention, the shoe upper component pattern includes a main shoe upper pattern, a heel counter pattern, an eyelet pattern, a tongue pattern, or a combination thereof.

[0029] When heat transfer material 1 is Figure 1 Thermal transfer material 1A, Figure 2 Heat transfer material 1B, or Figure 5When using heat transfer material 1E, the shoe upper fabric 2 with the transferred pattern is heat-transferred and can be cut and sewn into a three-dimensional shoe upper (not shown). In this embodiment of the invention, the three-dimensional shoe upper has a seam, and the shoe upper fabric 2 on both sides of the seam of the three-dimensional shoe upper has the same transfer pattern. In this embodiment of the invention, the three-dimensional shoe upper has a cover (not shown), and this cover is used to cover the seam.

[0030] For example, after the main shoe upper is made using heat transfer material 1A, the first transfer pattern area 12 and two second transfer pattern areas 14a and 14b are transferred onto the shoe upper fabric. After the shoe upper fabric is cut and the side edges 14a1 and 14b1 are sewn together, the second transfer pattern of the second transfer pattern area 14a and the third transfer pattern of the second transfer pattern area 14a can be joined together to form a continuous pattern.

[0031] In this embodiment of the invention, when the heat transfer material 1 is Figure 5 When using heat transfer material 1E, transfer patterns of the main upper, eyelets, and heel counter can be transferred onto the same upper fabric 2. Furthermore, the main upper, eyelets, and heel counter with the transfer patterns can be cut and sewn together to form another three-dimensional upper (not shown). In this embodiment of the invention, the three-dimensional upper has multiple seams, and the upper fabric 2 on opposite sides of the seams of the three-dimensional upper has the same transfer pattern.

[0032] For example, after the main shoe upper is made using heat transfer material 1A, the first transfer pattern area 12 and two second transfer pattern areas 14a and 14b are transferred onto the shoe upper fabric 2. After the eyelet is made using heat transfer material 1C, the transfer pattern area 18 is transferred onto the shoe upper fabric 2. After the heel tab is made using heat transfer material 1D, the transfer pattern area 19 is transferred onto the shoe upper fabric 2.

[0033] After the upper fabric 2 is cut and the upper fabric 2 having the second transfer pattern areas 14a, 14b and the transfer pattern area 19 is sewn together, the second and third transfer patterns of the second transfer pattern areas 14a, 14b and the transfer pattern of the transfer pattern area 19 can be joined together to form a continuous pattern. On the other hand, after the upper fabric 2 having the first transfer pattern area 12 and the transfer pattern area 18 is sewn together, the first transfer pattern of the first transfer pattern area 12 and the transfer pattern of the transfer pattern area 18 can be joined together to form another continuous pattern.

[0034] Please refer to this as well. Figure 6 and Figure 7 . Figure 7 This is a schematic diagram of a heat transfer mold 3 according to a preferred embodiment of the present invention. Figure 7 This is a schematic diagram of a preferred embodiment of the planar shoe upper pattern heat transfer mold 3 of the present invention. Figure 7In the middle, the transfer mold 3 includes an upper mold 30a and a lower mold 30b, wherein the upper mold 30a and the lower mold 30b are paired. Figure 7 Both the heat transfer material 1 and the shoe upper fabric 2 are planar, and the heat transfer mold 3 is also a mold used for transferring planar shoe upper patterns. The shoe upper fabric 2 is placed between the upper mold 30a and the lower mold 30b, and the heat transfer material 1 is placed between the shoe upper fabric 2 and the upper mold 30a.

[0035] Figure 6 System Utilization Figure 7 The shoe upper manufacturing method, designed with a flat shoe upper pattern transfer mold 3, can transfer a transfer pattern of the same size as the shoe upper pattern onto the shoe upper fabric 2. Then, the shoe upper fabric 2 with the transfer pattern is cut according to the shoe upper pattern. Therefore, no transfer pattern is transferred to the shoe upper fabric 2 outside the shoe upper pattern, thus avoiding waste of dye. Furthermore, since the shoe upper fabric 2 outside the shoe upper pattern is not dyed, these cut scraps are easy to recycle, further reducing waste.

[0036] Through the design of the embodiments of the present invention, the shoe upper provided by the present invention has a three-dimensional structure, which can make the shoe upper present a three-dimensional pattern effect. In addition, the shoe upper manufacturing method provided by the present invention can transfer the transfer pattern of the same size as a shoe upper pattern to the shoe upper fabric, and then cut the shoe upper fabric with the transfer pattern according to the shoe upper pattern, thereby avoiding waste of pigment and making the cutting residue easy to recycle, reducing the amount of waste.
