Problems solved by technology
The waterproof non-woven fabric used in the existing technical solutions is not an environmentally friendly material, because PVC is a slightly toxic material that is harmful to the human body. In 2017, the health organization clarified that PVC has carcinogenic hazards. The waterproof performance of cloth is relatively poor
For the production of waterproof non-woven fabrics, there are the following defects: it is not convenient to clamp the main body of the environmental protection waterproof non-woven fabric, it cannot prevent the deviation of the main body of the environmental protection waterproof non-woven fabric, and it is not convenient for cooling and secondary pressurization, so that the environmental protection waterproof non-woven fabric The body is not tight enough and the structure is not strong enough; in view of this defect, it is necessary for us to design an environmentally friendly waterproof non-woven fabric and its production process

Abstract
The invention discloses an environment-friendly waterproof non-woven fabric and a production process, comprising a first PP non-woven fabric layer, a PE casting film layer and a second PP non-woven fabric layer, the first PP non-woven fabric layer, a PE flow The cast film layer and the second PP non-woven fabric layer form an environmentally friendly waterproof non-woven fabric body, and the first PP non-woven fabric layer and the second PP non-woven fabric layer are laminated on both sides of the PE cast film layer; wherein , the weight of the environmentally friendly waterproof nonwoven fabric per square meter is 250g, and the first PP nonwoven fabric layer, PE cast film layer and second PP nonwoven fabric in the environmentally friendly waterproof nonwoven fabric body per square meter are The layer weight component ratio is 2:1:2; the present invention will not cause any pollution, and is harmless to the human body. Due to its strong strength, high thickness, good friction resistance, and super water resistance; it is convenient to prevent environmental protection and waterproof The offset of the non-woven fabric body is conducive to moving hot-press bonding, and at the same time it is convenient for cooling and secondary pressure, making the environmentally friendly waterproof non-woven fabric body more compact and the structure stronger.
Description
technical field [0001] The invention relates to the technical field of environmentally friendly waterproof nonwoven fabrics, in particular to an environmentally friendly waterproof nonwoven fabric and a production process. Background technique [0002] There are many kinds of waterproof non-woven fabrics, the most common one is PVC waterproof non-woven fabric, which adopts two-layer composite method. The waterproof non-woven fabric used in the existing technical solutions is not an environmentally friendly material, because PVC is a slightly toxic material that is harmful to the human body. In 2017, the health organization clarified that PVC has carcinogenic hazards. The waterproof performance of cloth is relatively poor. For the production of waterproof non-woven fabrics, there are the following defects: it is not convenient to clamp the main body of the environmental protection waterproof non-woven fabric, it cannot prevent the deviation of the main body of the environmen...
