[0034] Embodiment 1

[0035] The embodiment of the present invention provides a waterproof shoe upper, which can be compounded to a prefabricated sole by means of bonding, hot melting or sewing, and the two cooperate to form a shoe.

[0036] Refer to Figure 1The waterproof shoe upper provided in this embodiment mainly includes an upper layer 1, a protective layer 4, a first reinforcement component and a second reinforcement component.

[0037] Among them, the upper layer 1 is formed by weaving the first yarn 5 and the second yarn 6 by warp and weft, and a fastening knot 7 is provided at the intersection of the first yarn 5 and the second yarn 6; the first yarn 5 and the second yarn 6 both use waterproof yarn 8, and the waterproof yarn 8 includes an inner core wire 10 and a plurality of waterproof fibers 9 wrapped around the outside of the inner core wire 10, and each of the waterproof fibers 9 is spirally wound around its corresponding inner core wire 10; the fastening knot 7 is formed by two of the waterproof yarns 8 being staggered and tied to the intersection of the first yarn 5 and the second yarn 6.

[0038] In this embodiment, the waterproof fiber 9 is made of polyester fiber coated with a waterproof agent. The inner core wire 10 is a heat-insulating polyester fiber, which is made of a mixture of polyester and acrylic fiber.

[0039] Specifically, refer to Figure 2 The upper layer 1 is the main component of the waterproof upper. The upper layer 1 is formed by weaving the first yarn 5 and the second yarn 6 in warp and weft. The first yarn 5 and the second yarn 6 both use the waterproof yarn 8 of the same structure. At the same time, a fastening knot 7 is provided at the interweaving of the first yarn 5 and the second yarn 6. The fastening knot 7 is also formed by the waterproof yarn 8. Figure 4 The waterproof yarn 8 includes an inner core wire 10 and multiple waterproof fibers 9. These waterproof fibers 9 are spirally wound around the inner core wire 10, ensuring that the waterproof yarn 8 has waterproof properties in multiple directions, thereby improving the overall waterproof effect of the upper layer 1. At the same time, the winding method of the waterproof fiber 9 on the inner core wire 10 makes the waterproof yarn 8 itself have higher tensile strength and wear resistance, and will not affect the softness and comfort of the upper layer 1.

[0040] Reference Figure 3 The fastening knot 7 is formed by two waterproof yarns 8 interlaced and tied at the interlaced part of the first yarn 5 and the second yarn 6. Since the first yarn 5 and the second yarn 6 are woven by warp and weft weaving, the first yarn 5 and the second yarn 6 have multiple interlaced parts. At these parts, the first yarn 5 and the second yarn 6 are in an overlapping state extending in an orthogonal direction. Two waterproof yarns 8 are respectively passed through the first yarn 5 and the second yarn 6 at these interlaced parts, and then they are wound back and tied to each other, so that the first yarn 5 and the second yarn 6 are tightened and fixed by the fastening knot 7 at the interlaced part. Specifically, during weaving, one yarn can be woven in the warp or weft direction each time during the weaving process of the first yarn 5 and the second yarn 6, and the waterproof yarn 8 can be tied at the corresponding interlaced part synchronously to form the fastening knot 7. The fastening knots 7 along the warp or weft direction can be connected to each other, so that the fastening knots 7 form a whole.

[0041] The upper layer 1 of the shoe upper provided in the present embodiment is formed by weaving the waterproof yarn 8 in warp and weft, and a fastening knot 7 is provided at the interweaving of the yarn, wherein the waterproof yarn 8 includes an inner core wire 10 and a plurality of waterproof fibers 9 wrapped around the outer side of the inner core wire 10, and these waterproof fibers 9 are spirally wound around the inner core wire 10. The yarn of this composite structure can effectively improve the structural strength of the waterproof yarn 8. At the same time, the winding method of the waterproof fiber 9 can effectively fill the gap formed when the first yarn 5 and the second yarn 6 are woven, thereby ensuring the waterproof effect of the upper layer 1. In addition, the two The first and second yarns 5, 6 are interlaced and tied to each other at the intersection of the first and second yarns 5, 6 to form a fastening knot 7. When the upper layer 1 is deformed by force, the fastening knot 7 will pull the interlaced first and second yarns 5, 6 to avoid a large gap between the first and second yarns 5, 6. In this way, even when the upper layer 1 is deformed by force, the waterproof effect of the upper layer 1 can be guaranteed. Since the upper layer 1 of the waterproof shoe upper is woven with the waterproof yarn 8, it is not easy to be damaged, so it can effectively improve the problem that the waterproof effect of the existing waterproof shoe upper is easily weakened.

[0042] The waterproof fiber 9 is made of polyester fiber coated with a waterproof agent, and the waterproof agent is a Durable WaterRepellent product. This coating process can form a waterproof coating on the outer surface of the waterproof fiber 9, so that the manufactured upper layer 1 can prevent water molecules from penetrating.

[0043] The inner core wire 10 is made of heat-insulating polyester fiber, which is a mixture of polyester and acrylic fiber and can provide a good heat-insulating effect.

[0044] In addition, refer to Figure 1 , a protective layer 4 made of waterproof fabric extends along the edge of the upper layer 1 and is arranged on the outer surface of the upper layer 1 corresponding to the connection between the upper and the sole. Specifically, the protective layer 4 can be arranged on the upper layer 1 by hot pressing, bonding and / or sewing, which can further improve the waterproof effect of the upper layer 1, and the protective layer 4 is arranged at the connection between the upper and the sole. When the upper is compounded to the sole, the protective layer 4 can further improve the waterproof effect of the connection between the upper and the sole. Among them, the waterproof fabric used in the protective layer 4 is a composite of a polytetrafluoroethylene membrane and a polyester cloth. The polytetrafluoroethylene (PTFE) membrane has extremely strong waterproof properties, and the microporous structure of the PTFE membrane can effectively block the penetration of liquid water while allowing water vapor to pass through, achieving the dual effects of waterproof and breathable. The protective layer 4 formed by compounding with the polyester cloth provides a reliable waterproof barrier to prevent external moisture from entering the shoe.

[0045] Reference Figure 1, two sets of first reinforcement components are respectively located on both sides of the width of the shoe upper, and two sets of second reinforcement components correspond to the two sets of first reinforcement components respectively. Among them, each set of first reinforcement components includes two first reinforcing ribs 2 arranged in parallel along the width direction of the shoe upper; the first reinforcing ribs 2 are made of thermoplastic polyurethane elastomer material, and are hot-pressed, bonded and / or stitched to the shoe upper layer 1. Each set of second reinforcement components includes a second reinforcing rib 3 extending along the length direction of the shoe upper and located between the two first reinforcing ribs 2 of the corresponding first reinforcement component; the second reinforcing rib 3 is made of thermoplastic polyurethane elastomer material, and is hot-pressed, bonded and / or stitched to the shoe upper layer 1.

[0046] Specifically, both the first reinforcing rib 2 and the second reinforcing rib 3 are made of thermoplastic polyurethane elastomer material, that is, TPU, so that the first reinforcing rib 2 and the second reinforcing rib 3 have good toughness and can provide additional support for the shoe upper. Among them, a set of first reinforcement components includes two first reinforcing ribs 2, and these two first reinforcing ribs 2 extend along the width direction of the shoe upper, from the position of the shoe upper corresponding to the tongue to the position of the protective layer 4, so that the shoe upper has better structural stability in the corresponding direction; a set of second reinforcement components includes a second reinforcing rib 3, and this second reinforcing rib 3 is arranged between the two first reinforcing ribs 2 of a set of first reinforcement components and extends along the length direction of the shoe upper, which can make the shoe upper also have better structural stability in this direction. By setting the first reinforcement components and the second reinforcement components, the stability of the shoe upper is better, it is less likely to deform, and the waterproof effect can be maintained better.
