 [0023] In the embodiment, the waterproof gas permeable material structure includes, in order from the outside to the inside, a first PET layer 1, a TPU film layer 2, and a second PET layer 3, wherein:

[0024] The first PET layer 1 includes a first PET layer flat plate 13 and ribs 12, a first venting hole group 14 and a water leakage portion 11 disposed on the first PET layer flat plate, and the water leakage portion 11 and The first venting holes 14 are directly connected;

 [0025] an outer surface of the rib 12 is connected to the TPU film layer 2;

 [0026] The second PET layer 3 is provided with a second venting hole group (not shown in FIG. 4), and the first venting hole group 14 is parallel to the second venting hole group and vertically disposed on the same plane. .

 [0027] In this embodiment, the waterproof gas permeable material structure includes a first PET layer 1, a TPU film layer 2, and a second PE T layer 3; the first PET layer 1 includes a first PET layer flat plate 13 and is disposed at the same The rib 12 on the first PET layer flat plate, the first venting hole group 14 and the water leakage portion 11 are described. The first PET layer 1 is also referred to as a water leakage PET layer, and the water leakage portion 11 is connected to the first venting hole group 14, the water leakage portion 11 includes a plurality of water leakage holes, which are not shown in FIG. The group 14 includes at least two venting holes, which are not shown in the drawing, so that the water leakage portion 11 is connected to the first PET layer flat plate 13 through the first venting hole group 14, when the waterproof gas permeable material contacts the rainwater raft, The first PET layer 1 on the outer surface leaks rainwater through the water leakage portion 11; since the outer surface of the rib 12 is connected to the TPU film layer 2, rainwater leaking from the water leakage portion 11 penetrates into the TPU film layer 2. Since the TP U film layer 2 is composed of a TPU waterproof gas permeable membrane, it has the function of waterproofing and ventilating, thereby preventing rainwater from entering the inner surface of the waterproof gas permeable material structure, that is, reaching the second PET layer 3, thereby achieving waterproof effect.

 [0028] In the embodiment, the rib 12 includes a horizontal rib and a longitudinal rib, the horizontal rib and the longitudinal rib are not shown in the figure, and the horizontal rib and the longitudinal rib pass the first venting The hole group 14 is connected; the number of the horizontal ribs is at least two, and the number of the longitudinal ribs is at least two. The transverse ribs and the longitudinal ribs are connected by a first venting opening group 14. Vent holes in the first venting hole group 14 are provided at intersections of the lateral ribs and the longitudinal ribs.

[0029] In this embodiment, the TPU film layer 2 is composed of a TPU waterproof gas permeable membrane, and the TPU waterproof gas permeable membrane has a thickness of 0.02 to 0.2 mm. TPU is the abbreviation of ' Thermoplastic Urethane', the Chinese name is thermoplastic polyurethane elastomer. TPU has high tensile strength, high tensile strength, toughness and aging resistance, TPU is a kind An environmentally friendly material for high molecular polymers, also known as a waterproof and moisture permeable film. It not only has most of the characteristics of rubber and ordinary plastics, but also has excellent comprehensive physical and chemical properties, so it is also called future material. TPU film is a film made of TPU pellets and processed by a special process. TP u film has high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, weather resistance, etc.

It also has many functions such as high water repellency, moisture resistance, wind resistance, cold resistance, antibacterial, mildew proof, warmth, UV resistance and energy release.

The vent hole 31 has a circular or elliptical shape. When the insulating PET layer on the inner surface is in contact with the skin of the user, the sweat or steam generated by the user during the movement is first volatilized into the second venting hole group of the second PET layer 3, due to the first venting hole. The group 14 is parallel to the second venting hole group and vertically disposed on the same plane, so that the TPU film layer 2 in the intermediate position reaches the first venting hole group 14 of the first PET layer 1, thereby moving the user during the movement. The sweat or steam generated in the discharge is exhausted to achieve a breathable, dry effect.

 [0031] The present invention also provides a waterproof and breathable shoe composed of a plurality of components, at least one of which is made of the above-described waterproof and breathable material structure. When people use the waterproof and breathable shoes to move or walk, the TPU film on the shoes can transmit sweat or steam generated on the feet, and the sweat or steam passes through the first vent hole group and the second vent hole group and the outside air. Exchange, to achieve gas convection inside and outside the shoe, to maintain the dryness of the shoe. Similarly, when walking on rainy or watery roads, the TPU film on the shoes can block the water outside the shoes from penetrating into the shoes, thus playing a waterproof and breathable role. Therefore, the waterproof and breathable shoes provided by the utility model not only bring a higher comfort to people's walking, but also have a simple design, easy production and low cost, and have wide practicality.
