Embodiment 1

[0012] A waterproof breathable cotton cloth, comprising a waterproof layer and a cotton cloth layer, the thickness of the waterproof layer is 0.03mm, and the thickness of the cotton cloth layer is 0.15mm.

[0013] The waterproof layer is made of the following raw materials in parts by weight: 25 parts of polyvinyl alcohol, 30 parts of p-toluenesulfonic acid, 50 parts of sodium o-hydroxybenzoate, 30 parts of silicon dioxide, 20 parts of anhydrous sorbic acid stearate, surface Active agent sodium dodecylbenzenesulfonate 25 parts.

[0014] Preparation of the waterproof layer: Mix all the raw materials evenly.

Embodiment 2

[0016] A waterproof breathable cotton cloth, comprising a waterproof layer and a cotton cloth layer, the thickness of the waterproof layer is 0.02mm, and the thickness of the cotton cloth layer is 0.1mm.

[0017] The waterproof layer is made of the following raw materials in parts by weight: 20 parts of polyvinyl alcohol, 20 parts of p-toluenesulfonic acid, 40 parts of sodium o-hydroxybenzoate, 20 parts of silicon dioxide, 10 parts of anhydrous sorbic acid stearate, surface Active agent stearic acid 20 parts.

[0018] Preparation of the waterproof layer: Mix all the raw materials evenly.

Embodiment 3

[0020] A waterproof breathable cotton cloth, comprising a waterproof layer and a cotton cloth layer, the thickness of the waterproof layer is 0.04mm, and the thickness of the cotton cloth layer is 0.2mm.

[0021] The waterproof layer is made of the following raw materials in parts by weight: 30 parts of polyvinyl alcohol, 40 parts of p-toluenesulfonic acid, 60 parts of sodium o-hydroxybenzoate, 40 parts of silicon dioxide, 30 parts of anhydrous sorbic acid stearate, surface Active agent sodium dodecylbenzenesulfonate 30 parts.

[0022] Preparation of the waterproof layer: Mix all the raw materials evenly.

[0023] Performance parameter of the present invention:

[0024]

[0025] It can be seen from the above that the water repellency of the present invention is still greater than 2 after washing, and the air permeability is 150-182m 3 / m 2 s, indicating that the present invention has good waterproof and breathable performance.
