Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] refer to figure 1 and figure 2 , is an embodiment of the composite thin-layer object 100 of the present invention, and the composite thin-layer object 100 includes a first layer body 1 and a second layer body 2 stacked on the first layer body 1 .

[0022] The first layer body 1 is made of high molecular polymers such as polypropylene (PP), polyester (PET), nylon (NYLON), and includes a first bottom surface 11 and a bottom surface opposite to the first bottom surface 11. The first top surface 12, a plurality of first protrusions 13 raised on the first top surface 12, a plurality of first depressions 14 formed in depressions on the first top surface 12, and a plurality of first depressions 14 formed through the first top surface 12. The first bottom surface 11 and the first top surface 12 are distributed in the first protruding portion 13 , th...

Abstract

The invention discloses a composite thin-layer object and a manufacturing method thereof. The composite thin-layer object comprises a first layer body and a second layer body. The first layer body comprises a first bottom face, a first top face opposite to the first bottom face, a plurality of first protruding parts formed on the first top face in a protruding mode, and a plurality of first brokenholes which penetrate through the first bottom face and the first top face and are at least distributed in the first protruding parts. The second layer body and the first layer body are laminated andthe second layer body comprises a second bottom surface overlapping the first top surface, a second top surface opposite to the second bottom surface, second protruding parts formed on the second topsurface in a protruding mode and attached to the first protruding parts in an overlapping mode respectively, and second broken holes penetrating through the second bottom face and the second top faceand at least distributed in the second protruding parts, wherein the second broken holes communicate with the first broken holes. Through the laminated arrangement of the first layer body and the second layer body and the structural configuration of the first broken holes and the second broken holes, the air permeability and the liquid permeability of the composite thin-layer object can be effectively adjusted.

Description

technical field [0001] The invention relates to a thin-layer object and a manufacturing method thereof, in particular to a composite thin-layer object formed of non-woven fabric or an adhesive film and a manufacturing method thereof. Background technique [0002] Non-woven fabric is a thin layer of melted fibers made of polymer melted materials. Its material, characteristics and manufacturing method are different from cloth textiles. It has been widely used in the production of sanitary products such as diapers or clothing. In addition to non-woven fabrics, there are also application methods of using film materials such as polypropylene (PP for short) to make sanitary products and clothing. For the air permeability and liquid permeability of the above-mentioned thin layers such as non-woven fabrics and adhesive films, it can generally be adjusted by changing the fiber weaving density and forming holes, etc. However, the above-mentioned methods still have certain limitations....
