The magic hooks and the magic cotton bodies are bonded to combine and connect the two polyester-spandex stretch fabric bodies, making it convenient to change the size of the fabric according to the needs.

[0010] Preferably, the thickness of the magnesium hydroxide layer is 0.5-0.7 cm, which can be determined according to the situation. Here, the thickness of the magnesium hydroxide layer is 0.6 cm.

[0011] Preferably, the thickness of the surface layer of the PTFE membrane is 0.4-0.6 cm, which can be determined according to the situation. Here, the thickness of the surface layer of the PTFE membrane is 0.5 cm.

[0012] Preferably, the surface layer of the PTFE membrane has a fibrillar microporous structure with a porosity of more than 85% and 1.4 billion micropores per square centimeter, so that it can effectively prevent external moisture from entering the surface layer of the PTFE membrane and avoid soaking damage to the magnesium hydroxide layer and the polyester ammonia layer, so that the overall waterproof performance of the fabric can be improved, making the overall fabric more resistant to washing, and will not affect the breathability of the fabric itself.
