[0012] Technical solution eight based on technical solution six or seven: the outer surface of the deodorizing layer is bonded to the inner surface of the upper layer and the elastic supporting layer is clamped and fixed, and the outer surface of the cooling layer is bonded to the inner surface of the deodorizing layer.

[0013] In addition, the utility model also provides technical solution nine: a shoe, which includes a sole, and the sole is compounded with the yellowing-resistant stringed silk upper as described in any one of technical solutions one to eight.

[0014] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0015] Technical solution one provides a yellowing-resistant stringed silk shoe upper, which includes an outermost upper layer, which is formed by laying polyester yarn. The single-layer or multi-layer laying method can adjust the structural strength and breathability of different positions of the upper according to actual needs; the polyester yarn used in the upper layer includes an inner core thread, and a polyester layer is coated on the outer side of the inner core thread, and the polyester layer uses an aliphatic thermoplastic polyurethane material; because the molecular structure of the aliphatic thermoplastic polyurethane material does not contain benzene rings, it can effectively reduce the chemical reaction caused by ultraviolet rays, thereby improving the yellowing resistance of the upper layer; and, instead of using a simple thermoplastic polyurethane thread directly as the yarn for manufacturing the upper layer, the aliphatic thermoplastic polyurethane material is used as a coating layer, which is coated on the outer side of the inner core thread. This not only allows the polyester yarn to have the good mechanical properties and weather resistance of thermoplastic polyurethane, improves the structural stability and waterproofness of the upper layer, but also can adapt to different needs by adjusting the material of the inner core thread.

[0022] In technical solution eight, the upper layer, deodorizing layer, elastic support layer and cooling layer are firmly bonded to form a whole, thereby improving the overall structural strength and durability of the shoe.

[0036] Example 1

[0037] Reference Figure 1The embodiment of the present invention provides a yellowing-resistant stringed silk shoe upper. The shoe upper 1 can be compounded to a prefabricated sole by bonding, hot melting or sewing, and the two can be combined to form a shoe.

[0038] Reference Figure 2 The yellowing-resistant stringed silk shoe upper provided in this embodiment includes a shoe upper layer 1 located on the outermost side, and an elastic support layer 12, a deodorizing layer 13 and a cooling layer 14 located on the inner side of the shoe upper layer 1 and arranged in sequence from the outside to the inside.

[0039] The upper layer 1 is formed by laying polyester yarn in a single layer and / or multiple layers according to the shape of the upper 1. Specifically, when forming the upper layer 1, a laying range can be first defined according to the shape of the upper 1. The polyester yarn is then laid on a plane according to a predetermined direction. If a certain part of the upper 1 requires higher strength, the polyester yarn can be laid in multiple layers at the corresponding part. If a certain part of the upper 1 requires better breathability, the polyester yarn can be laid in a single layer at the corresponding part. At the locations where multiple layers are laid, the overlapping polyester yarns can be connected by heat-melting and pressing. At other locations, if the polyester yarns overlap during the laying process, they can also be connected by heat-melting and pressing at the overlapping locations. At the edges of the upper 1, the polyester yarns arranged in other directions on the inner side can be connected into one piece by the polyester yarns extending along the edges of the upper 1. Through this laying method, the polyester yarns are intertwined back and forth, and a mesh structure is formed through the nodes at the overlapping locations, thereby providing higher strength and stability.

[0040] Among them, reference Figure 3 The polyester yarn includes an inner core yarn 112, and the inner core yarn 112 is coated with a polyester layer 111. The polyester layer 111 is an aliphatic thermoplastic polyurethane material. Because the molecular structure of the aliphatic thermoplastic polyurethane material does not contain benzene rings, it can effectively reduce chemical reactions caused by ultraviolet rays, thereby improving the yellowing resistance of the upper layer 1. In addition, instead of using a simple thermoplastic polyurethane yarn directly as the yarn for manufacturing the upper layer 1, the aliphatic thermoplastic polyurethane material is used as the coating layer 111, which is coated on the outer surface of the inner core yarn 112. This not only allows the polyester yarn to have the good mechanical properties and weather resistance of thermoplastic polyurethane, improving the structural stability and waterproofness of the upper layer 1, but also allows the material of the inner core yarn 112 to be adjusted to meet different needs.

[0041] In this embodiment, the inner core wire 112 is two twisted hemp ropes, which have high mechanical strength. The outer side is coated with thermoplastic polyurethane, which can further improve the strength and wear resistance of the polyester yarn.

[0042] Reference Figure 2The elastic support layer 12 includes a plurality of elastic support strips 121 arranged at intervals and extending along the length of the upper 1. The elastic support strips 121 are periodically curved along the thickness direction of the upper 1. Specifically, the elastic support layer 12 is disposed between the upper 1 and the deodorizing layer 13. The elastic support strips 121 extend forward along the length of the upper 1, that is, along the length of the shoe. These elastic support strips 121 are arranged so as to cover the entire upper 1. At the same time, adjacent elastic support strips 121 are spaced apart along the width of the shoe, which not only facilitates the arrangement of the elastic support strips 121 but also ensures that the overall elasticity of the upper 1 is within an appropriate range. Among them, the elastic support strip 121 is periodically curved, that is, it extends in a wave shape. This shape characteristic enables the elastic support strip 121 to have a certain deformation ability in the length direction of the upper 1. When the upper 1 is supported from the inside, the elastic support strip 121 will be stretched and absorb the impact energy at the same time. After that, the elastic support strip 121 restores its deformation, which protects the upper 1 and improves its elasticity.

[0043] The elastic support strip 121 is made of thermoplastic polyurethane, carbon fiber, nylon, or ethylene vinyl acetate copolymer. Each material of the elastic support strip 121 has its own specific advantages. Thermoplastic polyurethane has good elasticity and wear resistance, carbon fiber is yellowing-resistant and lightweight, nylon provides good durability and flexibility, and ethylene vinyl acetate copolymer has good impact resistance and softness. These materials can be used to select different performances as needed to further enhance the overall functionality of the upper 1.

[0044] In this embodiment, the cool layer 14 is formed by cross-weaving the antibacterial ice-sensing fibers 141 in warp and weft. Figure 4 The antibacterial ice-sense fiber 141 is formed by spirally wrapping ice silk fibers around silver fibers 142. Silver fibers 142 are composite fibers composed of a pure silver layer firmly attached to fibers such as nylon and polyester. Leveraging the antibacterial properties of silver, the resulting antibacterial ice-sense fiber 141 exhibits excellent antibacterial properties. Ice silk fibers, which provide a cool touch, are typically made from materials such as viscose fibers, polyester, and nylon. As a conventional commodity, commercially available ice silk fiber products can be used to create the shoe upper 1 provided in this embodiment.

[0045] Of course, in other embodiments, the cooling layer 14 may also be formed by cross-weaving conventional ice silk fibers in warp and weft. Ice silk fibers have excellent air permeability and moisture absorption and perspiration wicking capabilities, and can provide a cool wearing experience in hot weather, thereby improving the comfort of the shoes.

[0046] In this embodiment, the deodorizing layer 13 is formed by cross-weaving bamboo fibers in warp and weft. Bamboo fibers have natural deodorizing and antibacterial properties, which can effectively absorb and decompose odors generated in the shoes, keep the air in the shoes fresh, and improve wearing comfort.

[0047] In this embodiment, the outer surface of the deodorizing layer 13 is bonded to the inner surface of the upper layer 1, thereby sandwiching and securing the elastic support layer 12. The outer surface of the cooling layer 14 is bonded to the inner surface of the deodorizing layer 13. The upper layer 1, deodorizing layer 13, elastic support layer 12, and cooling layer 14 are firmly bonded together, forming a single unit, thereby enhancing the overall structural strength and durability of the shoe.

[0048] Example 2

[0049] Example 2 of the present invention provides a shoe, which includes a sole and the upper 1 provided in Example 1. The upper 1 is compounded to the sole by bonding, hot melting, sewing, etc. Due to the use of the upper 1 of Example 1, the shoe has good yellowing resistance.

[0050] The above description and embodiments are used to explain the scope of protection of the utility model, but do not constitute a limitation on the scope of protection of the utility model. Based on the enlightenment of the utility model or the above embodiments, modifications, equivalent replacements, or other improvements to the embodiments of the utility model or part of the technical features thereof that can be obtained by ordinary technicians in this field through logical analysis, reasoning, or limited experiments in combination with common knowledge, ordinary technical knowledge in this field and / or existing technology should be included in the scope of protection of the utility model.
