Description
Technical Field
The utility model belongs to the technical field of the film and specifically relates to a complex film absorbs water of multilayer.
Background
Along with the development of society, the use of film is also more and more extensive, because its convenient to use, a great deal of characteristics such as with low costs, but the single performance of traditional film can not satisfy present demand yet, and the multi-performance of complex film, advantages such as low cost have replaced traditional single film gradually, the utility model relates to a multilayer complex film that absorbs water has water absorption, waterproof, ventilative effect, can use in medical a plurality of aspects, has fine spreading value.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a simple structure, soft texture, various, the convenient to use's of function multilayer complex film that absorbs water.
In order to achieve the above purpose, the technical scheme of the utility model:
the multilayer water absorption composite film comprises a non-woven fabric, a breathable film and a film, wherein a plurality of water absorption particles are arranged on the surface of the non-woven fabric, the non-woven fabric and the breathable film are bonded by a wet-type composite method, the bottom of the breathable film is bonded with the film through a water-dispersible adhesive, and the surface of the film is provided with embossing.
Preferably, the breathable film between the nonwoven fabric and the film is at least two layers.
Preferably, the nonwoven fabric and the breathable film are bonded by a wet-type composite method, and the specific binder is a water-soluble binder.
The utility model discloses a beneficial condition lies in: the utility model adopts the above technical scheme a multilayer complex film that absorbs water that provides, its characteristics: the structure is simple, the texture is soft, the function is various, and the use is convenient.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. non-woven fabrics; 2. a gas permeable membrane; 3. a film; 4. water-absorbing particles; 5. and (6) embossing.
Detailed Description
As shown in fig. 1, a multilayer water absorption composite film comprises a non-woven fabric 1, a breathable film 2 and a film 3, wherein a plurality of water absorption particles 4 are arranged on the surface of the non-woven fabric 1, the non-woven fabric 1 and the breathable film 2 are bonded by a wet-type composite method, the film 3 is bonded at the bottom of the breathable film 2 by a water-dispersible adhesive, an embossing 5 is arranged on the surface of the film 3, the breathable film 2 between the non-woven fabric 1 and the film 3 is at least two-layer, the non-woven fabric 1 and the breathable film 2 are bonded by the wet-type composite method, and the specific.
In actual use, the surface of the non-woven fabric 1 is provided with the plurality of water-absorbing particles 4, and the non-woven fabric 1 and the breathable film 2 are bonded by adopting a wet-type composite method, so that the non-woven fabric has the characteristics of stable performance, high raw material utilization rate, high production speed, high yield and the like; the breathable film 2 between the non-woven fabric 1 and the film 3 is at least two layers, so that after the non-woven fabric 1 absorbs moisture, the breathable film 2 can prevent water and enable air to enter and exit, and internal stuffiness and dampness can not be caused; the surface of the film 3 is provided with the embossing 5, and the design of the embossing 5 can increase the friction force, so that the use is more convenient.
It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to illustrate the principles of the invention, but rather that various changes and modifications may be made without departing from the spirit and scope of the invention, which shall fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
