Specifically, the anti-aging agent included in the waterproof layer 1 and/or the bonding wire 22 is a phosphite antioxidant, for example: phenol-free phosphite antioxidant, low-phenol phosphite antioxidant and phenol-containing phosphite antioxidant. By adding the anti-aging agent, the aging of the waterproof layer 1 and/or the woven layer 2 can be effectively slowed down, and the service life of the waterproof woven cloth is prolonged.

The reinforced PP material is prepared by mixing a common PP material and a toughening agent according to a certain proportion. Specifically, the toughening agent can be one and/or a combination of POE, EPDM and SBS. The proportion of the toughening agent is 15-20%. The maximum stretching force of the woven cloth made of the common PP material is about 300N, and the maximum stretching force of the reinforced PP material of the utility model is about 1300N. It is thus directly obtained that the use of reinforced PP material as the tensile filaments 21 in the knitted layer 2 greatly improves the tensile capacity of the knitted fabric.
