Preferably, the material of the substrate layer is a PTEE membrane material.
Preferably, the breathable layer is made of PE.
Preferably, the polytetrafluoroethylene film layer is made of polytetrafluoroethylene, and the non-woven fabric layer is made of non-woven fabric.
Preferably, the thickness of the waterproof layer is 0.8mm, and the material of the breathable layer is 1.0 mm.
Compared with the prior art, the utility model provides a waterproof ventilative membrane module possesses following beneficial effect:
this waterproof breathable membrane subassembly, base member layer through setting up, the polytetrafluoroethylene thin layer, a waterproof layer, ventilative layer, the fabric layer, the non-woven fabrics layer, PVC adhesive tape layer and PVC membrane, waterproof layer through setting up, make water unable to pass through the film, ventilative layer through setting up, make vapor can pass through the film, and then make the ventilated membrane have the permeable water vapor and the performance that can not permeate water, but wide application in sanitary towel, on sanitary products such as panty-shape diapers, use through the polytetrafluoroethylene thin layer cooperation base member layer that sets up simultaneously, support the ventilated membrane, non-woven fabrics layer through setting up, make the more comfortable of film use.
The part not involved in the device is the same as the prior art or can be realized by adopting the prior art, the breathable film of the utility model has the performance of permeating water vapor but not permeating water, and can be widely applied to sanitary products such as sanitary towels, paper diapers and the like.
Drawings
Fig. 1 is a schematic structural view of a waterproof breathable membrane assembly provided by the present invention.
In the figure: 1. a substrate layer; 2. a polytetrafluoroethylene film layer; 3. a waterproof layer; 4. a breathable layer; 5. a fabric layer; 6. a non-woven fabric layer; 7. a PVC rubber net layer; 8. PVC film.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, a waterproof and breathable film assembly comprises a substrate layer 1, a polytetrafluoroethylene film layer 2 is fixedly connected to one side of the substrate layer 1, waterproof layers 3 are fixedly connected to the side walls of the polytetrafluoroethylene film layer 2 and the substrate layer 1, and breathable layers 4 are symmetrically and fixedly connected to the side walls of the two waterproof layers 3 opposite to each other, wherein a fabric layer 5 is fixedly connected to the side wall of one breathable layer 4, a non-woven fabric layer 6 is fixedly connected to the side wall of the fabric layer 5 away from the polytetrafluoroethylene film layer 2, a PVC rubber net layer 7 is fixedly connected to the side wall of the other breathable layer 4, a PVC film 8 is fixedly connected to the side wall of the PVC rubber net layer 7 away from the polytetrafluoroethylene film layer 2, water cannot pass through the film through the arranged waterproof layer 3, water vapor can pass through the film through the arranged breathable layer 4, and the breathable film has the performance of water vapor permeability and water, but the wide application is on sanitary products such as sanitary towel, panty-shape diapers, and the while is used through 2 cooperation base member layers 1 on the polytetrafluoroethylene thin layer that set up, supports the ventilated membrane, through the non-woven fabrics layer 6 that sets up for the film is used more comfortablely.
The base layer 1 is made of PTEE membrane material, and the breathable layer 4 is made of PE material.
