Abstract
The utility model discloses a paper diaper, including liquid-permeable surface course, absorption sandwich layer and basement membrane layer, liquid-permeable surface course is composite sheet, composite sheet is formed by the non-woven fabrics heat recombination that is in the film of superficial layer and is in the bottom, liquid-permeable surface course has and runs through the trompil of superficial layer and bottom. The utility model discloses the liquidity surface course adopts composite sheet, and the trompil on its composite sheet can be effectual with body fluid water conservancy diversion to absorbing the sandwich layer, and the body fluid after the absorption can effectively be blocked to the film of superficial layer along fibre return channel again, has improved panty-shape diapers's absorptivity and dry and comfortable nature.
Description
Technical Field
The utility model relates to a hygienic product, in particular to a paper diaper.
Background
As a sanitary nursing product, the paper diaper is widely applied to infants, middle-aged and elderly people with easy urinary incontinence, patients with inconvenient movement and the like due to the characteristic of convenient replacement.
The disposable paper diaper commonly existing in the market is generally composed of a hydrophilic surface layer, an absorption core layer and a breathable basement membrane. Since the hot air non-woven fabric and the spun-bonded non-woven fabric have the advantages of softness, skin friendliness, high absorption speed and the like, the hot air non-woven fabric and the spun-bonded non-woven fabric are widely applied to the surface layer of the paper diaper. Because the non-woven fabrics makes the body fluid when reaching the surface course non-woven fabrics through fibrous capillary action, can flow guide to the absorption sandwich layer fast and absorbed by the absorption sandwich layer, but simultaneously under the effect of external pressure, for example user's self weight, the body fluid can return to the non-woven fabrics surface again along the fibre, consequently adopt the panty-shape diapers of non-woven fabrics surface course although soft comfortable, but the surface course can the wet sensation great after the imbibition, not dry and comfortable, if wear for a long time, irritate skin easily, form "red buttock thigh".
In view of this, the present inventors have made extensive conceptions for various defects and inconveniences caused by the incomplete design of the diaper, and have actively studied, improved and tried to develop and design the present invention.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a paper diaper which is soft, skin-friendly, dry and comfortable.
In order to achieve the above purpose, the solution of the present invention is:
a paper diaper comprises a liquid-permeable surface layer, an absorption core layer and a bottom film layer, wherein the liquid-permeable surface layer is a composite sheet, the composite sheet is formed by thermally compounding a film on a surface layer and a non-woven fabric on a bottom layer, and the liquid-permeable surface layer is provided with a plurality of holes penetrating through the surface layer and the bottom layer.
The surface layer film is provided with raised fibrous textures formed by wrapping the fiber surfaces of the bottom layer non-woven fabric through thermal compounding.
The height of the raised fibrous texture of the surface layer is 0.01-0.08 mm.
The mass of the surface layer of the liquid-permeable surface layer is 6-10 gsm.
The aperture ratio of the liquid-permeable surface layer is more than or equal to 8 percent.
The openings penetrating through the surface layer and the bottom layer on the liquid-permeable surface layer are funnel-shaped openings.
After the structure of the oil adding device is adopted, the utility model discloses a composite sheet that the non-woven fabrics heat recombination of film by the superficial layer and bottom formed and run through in the trompil of superficial layer and bottom as the liquid-permeable surface course on composite sheet, through the trompil of liquid-permeable surface course is with the body fluid water conservancy diversion to the absorption sandwich layer, and the superficial layer of liquid-permeable surface course is the film, has blocked the passageway that absorbs back body fluid along the fibre backward flow limitedly, has improved the dry and comfortable performance of panty-shape diapers.
Meanwhile, the surface layer film has lower weight and raised fibrous texture, so that the softness and skin-friendly performance of the liquid-permeable surface layer are greatly improved, the glossiness of the film is effectively reduced, and the plastic feeling is reduced.

FIG. 2 is a cross-sectional view taken along plane O-O' of FIG. 1;
fig. 3 is a plan view of a liquid-permeable top sheet according to a first embodiment of the present invention;
fig. 4 is a side view of a liquid-permeable top sheet according to a first embodiment of the present invention.
Detailed Description
As shown in fig. 1 to 2, the present invention discloses a diaper, which comprises a liquid-permeable surface layer 1, an absorbent core layer 2 and a bottom film layer 3, wherein the liquid-permeable surface layer 1 is a composite sheet, the composite sheet is formed by thermally compounding a film on a surface layer 11 and a non-woven fabric on a bottom layer 12, and the liquid-permeable surface layer 1 has a plurality of openings 13 penetrating through the surface layer 11 and the bottom layer 12.
The openings 13 are funnel-shaped or multi-step-shaped, the horizontal cross section of each opening 13 is circular, polygonal or irregular, the surface layer film is provided with raised fibrous textures formed by thermally compounding and coating the surface of the bottom layer non-woven fabric, the mass of the surface layer 11 is 6-10 gsm, the aperture ratio of the liquid-permeable surface layer 1 is more than or equal to 8%, and the height of the raised fibrous textures of the surface layer 11 is 0.01-0.08 mm.
The utility model discloses a permeable surface layer 1 adopts film and non-woven fabrics composite sheet, has reduced panty-shape diapers's quality and thickness, because superficial layer 11 is film material, has effectively blocked the body fluid after being absorbed by absorption sandwich layer 2 and has flowed back along the fibre, and superficial layer 11 film covers and has formed protruding fibrous texture in bottom 12 non-woven fabrics fibre surface, has effectively reduced the glossiness of superficial layer 11 film, has reduced the plastic sense.
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
The first embodiment is as follows:
as shown in fig. 1 to 4, the plurality of openings 13 of the liquid-permeable surface layer 1 of the diaper are funnel-shaped openings 13 having a circular surface shape, wherein the weight of the surface layer 11 is 8gsm, and the opening ratio of the liquid-permeable surface layer 1 is 15%.
The embodiment guides the body fluid to the absorption core layer 2 through the funnel-shaped openings 13 penetrating through the surface layer 11 and the bottom layer 12, so that the flow guiding effect of the body fluid is effectively improved, and the dryness of the paper diaper is improved.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
