Problems solved by technology

[0004] However, when the cohesive force of the liquid is too large, the effect of destroying the surface tension of the liquid by the convex ribs 11 alone is not good, so how to conceive a perforated membrane with a good effect of destroying the surface tension of the liquid to improve the liquid penetration effect has become the subject of this paper. Inventing a subject for further improvement

Embodiment Construction

[0027] refer to figure 2 , the thin layer object 3 of the present invention includes a substrate 31, in this example, the substrate 31 is a perforated film made of a polyethylene (PE) material, of course the substrate 31 can also be polypropylene (PP) or composite material or non-woven fabric and other materials.

[0028] still as figure 2 , 3 As shown, the base body 31 has a first surface 311 and a second surface 312 opposite to the first surface 311 . The first surface 311 is protruded with a plurality of protruding ribs 313 arranged adjacent to each other. The protruding rib 313 surrounds and defines a plurality of polygonal diversion areas 314 , and each diversion area 314 is provided with a plurality of perforations 315 . In addition, a plurality of recessed areas 316 are arranged on the convex rib 313 , and the recessed areas 316 and the first surface 311 of the base body 31 are located on the same plane, so that the flow guiding area 314 can pass through the recess...

Abstract

The invention discloses a laminar object capable of controlling the flow direction of a fluid and a sanitary product with the laminar object. The laminar object comprises a matrix, the matrix is convexly provided with a plurality of convex ribs which are arranged adjacent with each other, the convex ribs surround and define a plurality of flow guide areas, the flow diversion areas are distributed with a plurality of through holes, the convex ribs are provided with a plurality of depressed areas, and the flow guide areas can be communicated with one another by means of the depressed areas. Thus the surface tension of the liquid can be effectively destroyed, and the liquid can be quickly guided to the adjacent flow guide areas through the depressed areas and is output through the through holes on the flow guide areas to ensure that the surface of the laminar object can keep dry.

Description

technical field [0001] The invention relates to a thin layer suitable for sanitary products, in particular to a thin layer capable of controlling liquid flow and a sanitary product with the thin layer. Background technique [0002] Generally, such as sanitary products such as sanitary napkins, diapers or medical pads, in order to prevent the absorbed liquid from leaking out, a leak-proof layer with the characteristics of quickly diverting liquid and preventing liquid back seepage is usually installed outside an absorbent cotton body to prevent leakage. The layer is usually made of a perforated polyethylene film, which is in contact with the user's skin through the leak-proof layer to provide the user with a dry and comfortable feeling. [0003] Such as figure 1 As shown, the top surface of the perforated film 1 is generally formed with a plurality of roughly diamond-shaped convex ribs 11, and a plurality of hydrophobic holes 13 are formed in the diversion area 12 defined by...
