[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0016] Technical solution one provides a pair of shoes with a variable appearance color of the shoe upper. The shoe upper of this pair of shoes is provided with a color-changing area, and a water-repellent area is arranged around the outside of the color-changing area. The shoe upper outside the water-repellent area can be woven with yarns of conventional materials. Among them, the shoe upper is sequentially provided with a color-changing surface layer and a moisture-absorbing inner layer from outside to inside in the color-changing area. The color-changing surface layer is jointly woven by hydrophilic yarns and moisture-absorbing color-changing yarns. The moisture-absorbing color-changing yarns can change color when the humidity of its surrounding environment rises to a corresponding threshold. At the same time, the hydrophilic yarns have high water absorption performance and can quickly adsorb the water vapor in the surrounding environment to increase their own humidity. By jointly weaving the moisture-absorbing color-changing yarns and the hydrophilic yarns, and using the fast moisture-absorbing performance of the hydrophilic yarns, the moisture-absorbing color-changing yarns can also show color changes when the humidity of the surrounding environment is low. In addition, a moisture-absorbing inner layer is also arranged in the color-changing area. The moisture-absorbing inner layer is woven by hydrophilic yarns and is connected to the color-changing surface layer. And the moisture-absorbing inner layer is located on the inner side of the shoe upper, can directly contact the inner cavity of the shoe upper and contact with the human foot. When the human foot sweats, because the moisture-absorbing inner layer is woven with hydrophilic yarns, the hydrophilic yarns use their fast moisture-absorbing performance to gather the sweat water vapor in the nearby position. At the same time, because the moisture-absorbing inner layer is connected to the color-changing surface layer, the water vapor absorbed by the moisture-absorbing inner layer will be transported to the color-changing surface layer and act together with the hydrophilic yarns in the color-changing surface layer to make the moisture-absorbing color-changing yarns produce color changes. And, a water-repellent area is arranged around the outside of the color-changing area. The function of the water-repellent area is to block the transfer of water vapor from the color-changing area to the shoe upper outside the water-repellent area, that is, to gather the water vapor at the position of the color-changing area, increase the humidity of the color-changing area part, so that the color-changing area can produce color changes. Through this technical solution, the appearance color of the shoe upper is variable, which can meet the different needs of consumers.

[0017] In technical solution two, a moisture-conducting structure is also arranged in the moisture-absorbing inner layer. The moisture-conducting structure includes a plurality of contact protrusions and diversion grooves. The contact protrusions protrude from the diversion grooves. The contact protrusions can contact the foot more, and the diversion grooves will form a diversion gap between the moisture-absorbing inner layer and the outer surface of the foot. Air can flow through the diversion grooves, thereby driving the movement of water vapor, avoiding the stagnation of water vapor, and further improving the moisture-absorbing effect of the moisture-absorbing inner layer.

[0018] In technical solution three, a plurality of moisture-conducting strips are also arranged on the inner side of the shoe upper. The moisture-conducting strips can transport the water vapor in other parts of the shoe to the moisture-absorbing inner layer of the corresponding color-changing area. Thus, when the overall humidity inside the shoe is small, the color-changing area can also gather more water vapor to make the moisture-absorbing color-changing yarns produce color changes. At the same time, it can also improve the moisture-discharging performance of the shoe and improve the comfort of wearing the shoe.

[0019] In technical solution four, a moisture-conducting part is also arranged on the inner side of the shoe upper. The moisture-conducting part is provided with a moisture-conducting structure, and the use of the moisture-conducting structure can improve the moisture-absorbing effect of the moisture-conducting part on different parts inside the shoe.

[0020] In Technical Solution Five, the color-changing surface layer is formed by knitting the moisture-absorbing color-changing yarn and the hydrophilic yarn in a complex yarn parallel-twisting structure. This knitting method allows the two types of yarns to be evenly and tightly wound and in contact, which is conducive to the tight combination of the moisture-absorbing color-changing yarn and the hydrophilic yarn, enabling the moisture-absorbing color-changing yarn to come into contact with more water vapor.

[0021] In Technical Solution Six, the parallel-yarn ratio of the moisture-absorbing color-changing yarn and the hydrophilic yarn in the color-changing surface layer is 1:1. Since the two ratios are equal, it can ensure that the color-changing surface layer has a good moisture-absorbing effect without affecting the overall appearance of the color-changing area.

[0022] In Technical Solution Seven, the shoe upper can be woven with polyester, nylon, or thermoplastic polyurethane materials according to actual needs to provide different performances.

[0023] In Technical Solution Eight, the moisture-absorbing color-changing yarn is made of polyester fibers coated with an organic color-changing coating. This organic color-changing coating can undergo a reversible chemical change when the environmental humidity increases, thereby changing the color of the yarn and achieving the effect of variable appearance color of the shoe upper.

[0024] In Technical Solution Nine, the water-repellent yarn is made of polyester fibers treated with a water-repellent finishing agent. The water-repellent finishing agent changes the wetting property of the surface of the polyester fibers, making them hydrophobic, thus preventing water from entering the inner layer or reaching the surface layer from the inner layer.

[0025] In Technical Solution Ten, the hydrophilic yarn is made of acetate fiber containing hydrophilic groups, and the surface has a micro-groove structure, which can improve the moisture-absorbing efficiency of the hydrophilic yarn. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Embodiment

[0038] An embodiment of the present utility model provides a shoe with a variable appearance color of the shoe upper. Referring to Figure 1 , the shoe includes a shoe sole and a shoe upper 1, and the shoe upper 1 is laminated on the shoe sole, and the appearance color of the shoe upper 1 of the shoe is variable to meet different needs of consumers.

[0039] Among them, referring to Figure 1, the upper surface 1 of the shoe is provided with at least one color-changing area 2 and a water-repellent area 3 corresponding to each color-changing area 2 and surrounding the color-changing area 2. The upper surface 1 is provided with a color-changing surface layer 4 and a moisture-absorbing inner layer 5 in sequence from the outside to the inside in the color-changing area 2; the color-changing surface layer 4 is woven by hydrophilic yarns and moisture-absorbing color-changing yarns together, and the moisture-absorbing inner layer 5 is woven by hydrophilic yarns and is connected to the color-changing surface layer 4; the water-repellent area 3 is woven by water-repellent yarns and is connected to the color-changing surface layer 4 of the corresponding color-changing area 2.

[0040] Specifically, referring to Figure 1 , which shows one side of the shoe of this embodiment. In this side, it can be seen that there is a star-shaped area, which includes a color-changing area 2 and a water-repellent area 3. Among them, the color-changing area 2 is located inside, and the water-repellent area 3 is located outside the color-changing area 2 and surrounds the color-changing area 2 to separate the color-changing area 2 from other parts of the upper surface 1. For the upper surface 1 used in this embodiment, the part outside the color-changing area 2 and the water-repellent area 3 can be woven with polyester, nylon or thermoplastic polyurethane materials. The listed materials are only a preferred option and do not mean that these materials must be used to weave the upper surface 1. At the same time, the part of the upper surface 1 outside the color-changing area 2 and the water-repellent area 3 can adopt a single-layer structure or can be designed as a multi-layer structure, which depends on whether additional performance effects need to be provided for this part of the upper surface 1.

[0041] Referring to Figure 2 , in this embodiment, the color-changing surface layer 4 and the moisture-absorbing inner layer 5 are sequentially arranged from the outside to the inside at the position of the color-changing area 2, and the part outside the color-changing surface layer 4 is the water-repellent area 3 connected to the color-changing surface layer 4. The connection between the color-changing surface layer 4 and the water-repellent area 3 can be achieved by weaving.

[0042] Specifically, the color-changing part is woven by hydrophilic yarns and moisture-absorbing color-changing yarns together. The moisture-absorbing color-changing yarns can change color when the humidity of its surrounding environment rises to a corresponding threshold. At the same time, the hydrophilic yarns have high water absorption performance and can quickly adsorb water vapor in the surrounding environment to increase their own humidity. By weaving the moisture-absorbing color-changing yarns and hydrophilic yarns together and using the fast moisture absorption performance of the hydrophilic yarns, the moisture-absorbing color-changing yarns can also show color changes when the humidity of the surrounding environment is low. In addition, a moisture-absorbing inner layer 5 is provided in the color-changing area 2. The moisture-absorbing inner layer 5 is woven by hydrophilic yarns and is connected to the color-changing surface layer 4. And the moisture-absorbing inner layer 5 is located on the inner side of the shoe upper 1, can directly contact the inner cavity of the shoe upper 1 and contact with the human foot. When the human foot sweats, since the moisture-absorbing inner layer 5 is woven by hydrophilic yarns, the hydrophilic yarns can gather the sweat water vapor in the nearby position by using their fast moisture absorption performance. At the same time, because the moisture-absorbing inner layer 5 is connected to the color-changing surface layer 4, the water vapor absorbed by the moisture-absorbing inner layer 5 will be transported to the color-changing surface layer 4 and act together with the hydrophilic yarns in the color-changing surface layer 4 to make the moisture-absorbing color-changing yarns change color. And, a water-repellent area 3 is arranged around the outside of the color-changing area 2. The function of the water-repellent area 3 is to block the transfer of water vapor from the color-changing area 2 to the shoe upper 1 outside the water-repellent area 3, that is, to gather the water vapor at the position of the color-changing area 2 and increase the humidity of the color-changing area 2, so that the color-changing area 2 can produce color changes. Through this technical solution, the appearance color of the shoe upper 1 can be changed, which can meet the different needs of consumers.

[0043] Further, referring to Figure 2 , the moisture-absorbing inner layer 5 has a moisture-conducting structure 6; the moisture-conducting structure 6 includes a plurality of contact protrusions 7 and diversion grooves 8 arranged at intervals in sequence along a first direction. The contact protrusions 7 protrude towards the inner side of the shoe upper 1 relative to the diversion grooves 8, and the contact protrusions 7 and the diversion grooves 8 extend along a second direction perpendicular to the first direction. The first direction and the second direction therein refer to Figure 2 as shown.

[0044] It should be understood that the moisture-conducting structure 6 is a reusable structure. In this shoe, the moisture-conducting structure 6 is not only applied to the moisture-absorbing inner layer 5, but its principle of action and effect are the same. Specifically, the moisture-conducting structure 6 includes a plurality of contact protrusions 7 and diversion grooves 8. It can be considered that during the process of being formed by knitting yarns, the yarns are intentionally piled up to form a structure similar to a wave with both depressions and protrusions. Here, the wave shape means that when observing from the vertical section of the moisture-absorbing inner layer 5, the cross-section of the moisture-conducting structure 6 provided on the moisture-absorbing inner layer 5 is approximately wave-shaped. From this wave-shaped structure, it can be seen that the contact protrusions 7 protrude relatively towards the inner side of the shoe upper 1 compared to the diversion grooves 8. The contact protrusions 7 can contact the foot more, and the diversion grooves 8 will form a diversion gap between the moisture-absorbing inner layer 5 and the outer surface of the foot. Air can flow through the diversion grooves 8, thereby driving the movement of water vapor, avoiding the stagnation of water vapor, and further improving the moisture-absorbing effect of the moisture-absorbing inner layer 5.

[0045] At the same time, a plurality of moisture-conducting strips 9 formed by knitting hydrophilic yarns are provided on the inner side of the shoe upper 1; at least one moisture-conducting strip 9 is connected to the moisture-absorbing inner layer 5 of each color-changing area 2. The moisture-conducting strip 9 starts from the moisture-absorbing inner layer 5 of its corresponding color-changing area 2 and extends forward to the forefoot position of the shoe upper 1 and / or extends backward to the heel position of the shoe upper 1.

[0046] In addition, in cooperation with the moisture-conducting strip 9, a moisture-conducting part 10 formed by knitting hydrophilic yarns and corresponding to the moisture-conducting strip 9 one by one is provided on the inner side of the shoe upper 1. The moisture-conducting part 10 is located at the end of its corresponding moisture-conducting strip 9 relative to the color-changing area 2, and it has the above-mentioned moisture-conducting structure 6.

[0047] Specifically, according to the different actual structures of the shoe upper 1, the moisture-conducting strip 9 can be attached to the inner side of the single-layer shoe upper 1 or can be provided in the inner layer part of the multi-layer shoe upper 1. It can be adjusted according to the actual situation specifically. In this embodiment, the color-changing area 2 is set at a position slightly behind the middle in the front-back direction of the shoe upper 1. Therefore, the moisture-conducting strip 9 mainly starts from the color-changing area 2 and extends forward to the forefoot position of the shoe upper 1. If the color-changing area 2 is set at a position slightly in front of the middle in the front-back direction of the shoe upper 1, then the moisture-conducting strip 9 can start from the color-changing area 2 and extend backward to the heel position of the shoe upper 1. In short, how the moisture-conducting strip 9 is set should be adapted to the position of the color-changing area 2 to achieve the function of the moisture-conducting strip 9. Generally speaking, the moisture-conducting strip 9 can transport the water vapor in other parts of the shoe to the moisture-absorbing inner layer 5 of the corresponding color-changing area 2. Thus, when the overall humidity inside the shoe is relatively low, the color-changing area 2 can also accumulate more water vapor to cause the moisture-absorbing color-changing yarn to change color. At the same time, it can also improve the moisture-discharging performance of the shoe and the wearing comfort of the shoe.

[0048] The moisture-conducting part 10 is a part with an increased area set at the end of the moisture-conducting strip 9. It can be woven and formed together with the moisture-conducting strip 9, but its area is larger. The so-called larger area does not mean comparing the area of the moisture-conducting part 10 with the overall area of the moisture-conducting strip 9, but rather means that in terms of width, the moisture-conducting part 10 can be wider than the moisture-conducting strip 9, so as to improve the moisture absorption efficiency at the position of the moisture-conducting part 10. At the same time, a moisture-conducting structure 6 is provided on the moisture-conducting part 10, and the use of the moisture-conducting structure 6 can further improve the moisture absorption effect of the moisture-conducting part 10 on the inside of the shoes.

[0049] Furthermore, the color-changing surface layer 4 is woven by combining hydrophilic yarn and moisture-absorbing and color-changing yarn in a complex-filament and twisted structure, and the combined yarn ratio of the hydrophilic yarn and the moisture-absorbing and color-changing yarn in the color-changing surface layer 4 is 1:1.

[0050] Complex-filament and twisted combined yarn weaving is a conventional weaving method. Through this weaving method, the two kinds of yarns can be evenly and tightly wound and contacted, which is beneficial to the tight combination of the moisture-absorbing and color-changing yarn and the hydrophilic yarn, enabling the moisture-absorbing and color-changing yarn to contact more water vapor; and the combined yarn ratio of the hydrophilic yarn and the moisture-absorbing and color-changing yarn is equal, which can ensure that the color-changing surface layer 4 has a good moisture absorption effect without affecting the overall appearance of the color-changing area 2.

[0051] Among them, the moisture-absorbing and color-changing yarn is a polyester fiber coated with an organic color-changing coating, and the organic color-changing coating undergoes a reversible chemical change to change color when the environmental humidity increases. Specifically, an organic dye with an imino structure or a benzoquinone compound can be used.

[0052] In addition, the water-repellent yarn is a polyester fiber treated with a water-repellent finishing agent. The water-repellent finishing agent changes the wetting property of the surface of the polyester fiber, making it hydrophobic, thereby preventing moisture from entering the inner layer from the surface layer.

[0053] The hydrophilic yarn is an acetate fiber containing hydrophilic groups and having a microgroove structure on the surface, which can improve the moisture absorption efficiency.

[0054] It should be understood that the above-mentioned yarns used are all yarns commonly used in the prior art. Those skilled in the art can clearly know which yarns to use and which weaving methods to adopt to achieve the above-mentioned performance and effects through the above description.

[0055] A pair of shoes with a variable appearance color of the shoe upper provided by the present utility model is provided with a color-changing area 2 and a water-repellent area 3 on the shoe upper 1. The appearance color of the shoe upper 1 changes by absorbing the sweat and water vapor inside the shoes through the color-changing area 2 to meet the different needs of consumers.

[0056] The descriptions of the above specification and embodiments are used to explain the protection scope of the present utility model, but do not constitute a limitation to the protection scope of the present utility model. Through the inspiration of the present utility model or the above embodiments, those of ordinary skill in the art, combining common general knowledge, ordinary technical knowledge in the art and / or the prior art, can obtain modifications, equivalent replacements or other improvements to the embodiments of the present utility model or some of its technical features through logical analysis, reasoning or limited experiments, and all of them should be included within the protection scope of the present utility model.
