Detailed Description
The technical solution of the present invention will be further described with reference to the accompanying drawings and examples, so that those skilled in the art can more clearly understand the content of the technical solution.
As shown in fig. 1, the multi-layer non-woven fabric of the present invention comprises a first non-woven fabric layer 2 and a second non-woven fabric layer 8, wherein an aluminum film 1 is disposed on the side of the first non-woven fabric layer 2 and the side of the second non-woven fabric layer 8 away from each other; the aluminum film, the first non-woven fabric and the second non-woven fabric are connected through hot melt adhesive in a hot-pressing mode. Two layers of pearl cotton 6 are arranged on the other side of the second non-woven fabric layer 8, and a supporting grid sheet 7 is arranged between the two layers of pearl cotton 6. Here, the second non-woven fabric layer, the pearl wool and the supporting grid sheet may be sewn together by a thread. A PE film 5 is arranged on the other side of the pearl wool 6, a silver-loaded activated carbon fiber layer 3 is arranged on the other side of the PE film 5, and the silver-loaded activated carbon fiber layer 3 is connected with the first nonwoven fabric layer 2; the film in the embodiment is adhered to the pearl wool and the silver-loaded activated carbon fiber layer through glue. A plurality of air holes 4 are arranged on the aluminum film 1 close to the first non-woven fabric layer 2. The air holes in the embodiment can be obtained by needling, and the diameter of the air holes 4 is 0.3mm-0.5mm.
When in specific use, the air holes can be uniformly distributed on the aluminum film. When the material is used for manufacturing the food heat preservation bag, one side of the air hole is positioned at the inner side and is in contact with food. The air holes are arranged at the positions, so when smells are emitted, the silver-loaded activated carbon fiber layer can absorb the smells due to the existence of the air holes and prevent the smells from being emitted to the outside. And because the silver-loaded active carbon fiber layer is loaded with silver ions, the active carbon fiber layer can play a role in sterilization by utilizing the performance of the active carbon fiber layer, and can prevent bacteria from breeding in the active carbon fiber layer. And the pore diameter of the air holes is small, so the heat insulation performance of the material is not required. In addition, the PE film is provided in this embodiment, and when the internal air passes through the air holes, the internal air further touches the PE film, so the flow direction of the air near the air holes in the multi-layer nonwoven fabric in this embodiment is: non-woven fabric-silver-loaded active carbon fiber layer-PE film-silver-loaded active carbon fiber layer-non-woven fabric, namely the internal air can be blocked by the PE film and returns, so that the internal air can not flow to the outside; in addition, the external air is firstly blocked by the aluminum film, and the aluminum film is not provided with the air holes, so that the external air is difficult to penetrate through the aluminum film, and the two layers of pearl cotton are arranged in the aluminum film, so that the heat preservation performance is better, and the heat preservation effect can be realized. In addition, in the embodiment, the supporting grid sheet is arranged between the two layers of pearl cotton, so that the strength of the material is enhanced.
A plurality of parallel flow guide grooves 9 are formed in the aluminum film 1 close to one side of the second non-woven fabric, and the bottoms of the sections of the flow guide grooves 9 are arc-shaped. The guide groove is mainly used for facilitating rain or other liquid falling on the surface of a material to slide off when the material is used specifically.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalent substitutions may be made in some of the features of the embodiments; any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
