Abstract

The utility model discloses an eyelet touch membrane structure, the first side of which is provided with a capillary porocity extending to the second side. The capillary porocity forms a convex membrane angle on the second side of the membrane as well as forms a micropore of larger opening area in the second side of the membrane facing to the first side. The second side is used as the front side which is contacted with human skin when the membrane is applied. Because the membrane adopts vacuum or mechanical molding on capillary porocity molding, the membrane of each pore core is tore by force, so as to form a tore membrane angle protrusion in the second side of the membrane after the pore molding, and just the membrane angle protrusions will cause the reverse side of the membrane to form an unsmooth 'knap surface' that is used as the front side of hygienic articles which can increase the contact elasticity between membrane products and skin, thus improving the using comfort and simultaneously enhancing the roughness degree of membrane products which can prevent the flow rate of body fluid, further stop the side leakage of body fluid.

Description

Aperture sense of touch membrane structure

Technical field

This utility model is about a kind of thin film, is meant a kind of aperture sense of touch membrane structure that is widely used in disposable sanitary articles such as medical care mattress, women use sanitary napkin, protective pad, diaper as lining especially.

Background technology

Medical care with disposable sanitary articles such as mattress, sanltary towel for women use, protective pad and diaper in, particularly be purpose such as reach dry and comfortable, breathe freely, prevent to bleed back in women's disposable sanitary articles and the diaper, the widely-used making hole film of people is as lining.Known making hole film is that the employing TPO is a raw material, extrudes curtain coating through screw extruder and forms plastic sheeting, and make making hole film through the vacuum punching, and can get large and small hole or perforated structure.Cooperate shown in Fig. 1,2, its production method is that pore 2 ' and the micropore 3 ' of thin film all is that from thin film 1 ' first 11 ' punches in the same way to second 12 ', simultaneously with first 11 ' of this thin film 1 ' as the front that is applied to film product, and adopt its first 11 ' surface smoothing of making hole film of this explained hereafter, has plastic sheeting inherent plastic sense of institute and gloss, contact closely with human body skin easily, then in use cause the discomfort of user easily.

The utility model content

The purpose of this utility model provides a kind of aperture sense of touch membrane structure with matte sense of touch, so that it has softness, skin-friendly and use comfortable effect when being applied to required article surface.

For achieving the above object, solution of the present utility model is: a kind of aperture sense of touch membrane structure, and it is the pore in first oriented second extension of thin film, this pore forms the thin film angle of projection on second of thin film; Simultaneously on second of thin film, be extended with the bigger micropore of perforated area to first face; Second use front that conduct contacts with human body skin when thin film is used of thin film.

The aperture area of described micropore is not less than the perforated area of pore.

Described pore is the funnel type perforate.

The perforated area of described pore is 0.0025mm ²To 1.0mm ²

The best perforated area of described pore is 0.01mm ²To 0.2mm ²

After adopting such scheme, because this utility model is in when punching with plastic sheeting, change the manufacture of inherent pore of hacking in the same way and micropore, it is the mode that adopts the secondary punching, because this thin film is when the pore molding, be to adopt vacuum or mechanical type molding, the thin film of its each Kong Xin is ripped by force, thereby has the thin film angle projection of being ripped on second of the thin film that can be after pore forms, these thin film angle projectioies can make second formation rough " matte " of thin film just, utilize this " matte " to contact with human body skin, can possess following advantage as the front that is applied to hygienic article:

1, increases the contact resilient of film product and skin, improve the comfortableness of using;

2, increase the roughness of film product, can stop the flow velocity of body fluid, further prevent the body fluid side leakage.

The specific embodiment

Cooperate Fig. 3 to shown in Figure 6, aperture sense of touch membrane structure of the present utility model is to be extended with funnel type pore 2 at first 11 of plastic sheeting 1 to second 12, and the perforated area of pore 2 can be 0.0025mm ²To 1.0mm ², its best perforated area is 0.01mm ²To 0.2mm ²This pore 2 can form the thin film angle 21 of projection on second 12 of plastic sheeting 1; Simultaneously on second 12 of thin film, form the bigger micropore 3 of perforated area to first 11, these micropore 3 aperture areas are not less than the perforated area of pore 2, second the 12 use front (seeing shown in Fig. 7,8) that conduct contacts with human body skin when thin film is used of thin film.

Because this perforated film 1 is the front that second 12 conduct of its pore 2 molding of employing is applied to hygienic article, because of this thin film 1 when pore 2 molding, be to adopt vacuum or mechanical type molding, the thin film of its each Kong Xin is ripped by force, thereby can have thin film angle 21 projectioies of being ripped at second 12 of thin film after pore 2 forms, these thin film angle 21 projectioies can make second 12 of thin film 1 to form rough " matte " just.Cooperate shown in Fig. 7,8, utilize this " matte " as the front that is applied to hygienic article, above the thin film angle 21 of projection can increase the contact resilient of film product and skin, improve the comfortableness of use; Also can increase the roughness of film product simultaneously, can stop the flow velocity of body fluid, further prevent the body fluid side leakage.
