Problems solved by technology

However, in the production process of polymer absorbent paper, after the absorbent paper is cut into rolls, its two sides are open. During the production process of diapers, the superabsorbent resin is easy to fall off, and even falls outside the wrapping layer of diapers during the production process. or surface
At the same time, during the use of diapers, the fixing effect of the bulky non-woven fabric fiber is limited, and the superabsorbent resin is easy to run out and shift after absorbing liquid, which affects the wearing comfort

Embodiment 1

[0040] like Figure 1 to Figure 2 As shown, the perforated film 21 of the absorbent article is located between the liquid permeable surface layer 1 and the absorbent core 22, the openings 211 of the perforated film 21 are funnel-shaped, and the thickness of the perforated film 21 is 2 mm, so The volume of the single opening 211 is 58 mm 3 , the funnel-shaped opening 211 has a super absorbent resin 4 therein.

[0041] like Figure 3 to Figure 4 As shown, the absorbent article is compounded layer by layer, and the superabsorbent resin 4 is added to the absorbent layer 2 by in-line addition. During the adding process, since the perforated film 21 has openings 211, the high When the water absorbent resin 4 reaches the surface of the perforated film 21, it will roll down into the openings 211 of the perforated film 21. Since the perforated film 21 has a large thickness and a volume of the openings 211, it provides a certain amount of storage for the superabsorbent resin 4. spac...

Embodiment 2

[0044] like Figure 3 to Figure 4 As shown, the perforated film 21 of the absorbent article is located between the two layers of absorbent cores 221 and 222, the openings 211 of the perforated film 21 are funnel-shaped, the thickness of the perforated film 21 is 3.8 mm, and the The volume of a single opening 211 is 75 mm 3 , the funnel-shaped opening 211 has a super absorbent resin 4 therein.

[0045] During the use of this embodiment, since the perforated film 21 is located between the two layers of absorbent cores 221 and 222, the upper absorbent core 221 is relatively flat and is in contact with the liquid-permeable surface layer 1, so that the liquid-permeable surface layer 1 is more flat. , so that the overall touch of the absorbent article is softer and more comfortable. At the same time, after passing through the liquid permeable surface layer 1, the bodily fluid will be quickly absorbed by the upper absorbent core 221, and be guided to the perforated film 21 and the...

Embodiment 3

[0047] like Figure 3 to Figure 4 As shown, the perforated film 21 of the absorbent article is also provided with small holes 212a, and at least one small hole 212a is nested at the bottom of the openings 211 of the perforated film 21, and the openings of the perforated film 21 211 is stepped, the thickness of the perforated film 21 is 4.0 mm, and the volume of the single opening 211 is 82 mm 3 , the stepped opening 211 has a super absorbent resin 4 therein.

[0048] During the use of this embodiment, due to the large size and high thickness of the openings 211 of the perforated film 21, problems such as hole pattern collapse, deformation, winding or difficulty in maintaining the hole pattern in production are easily caused, and at least one small hole 212a is nested at the bottom of the opening 211 of the perforated film 21, which can increase the stiffness of the perforated film 21 and help to maintain the hole shape. At the same time, because the size of the openings 211...

Abstract

The invention discloses an absorbing product which comprises a liquid permeating surface layer, an absorbing layer and a bottom film layer. The absorbing layer is located between the liquid permeatingsurface layer and the bottom film layer. The absorbing layer comprises a perforated film and an absorbing core body, the perforated film is provided with an open hole running through the surface layer and the bottom layer of the perforated film, and super absorbent resin is arranged in the open hole of the perforated film. Due to the open hole in the perforated film in the absorbing layer, body fluid can be effectively guided to the absorbing core body and prevented from bleeding back, due to the fact that the super absorbent resin is arranged in the open hole of the perforated film, the super absorbent resin can be effectively prevented from being scattered or scattered to the outer layer of the absorbing product in the absorbing product production process, and the phenomenon that the absorbing layer is broken and caked due to the fact that the super absorbent resin is moved or shifted after water swelling of the super absorbent resin is avoided.

Description

technical field [0001] The present invention relates to a sanitary article, in particular to an absorbent article. Background technique [0002] Disposable absorbent products such as sanitary napkins, pads, and diapers currently on the market usually consist of a liquid-permeable surface layer, an absorbent layer, and a bottom film layer. The commonly used absorbent layer is composed of fluff pulp or dust-free paper. In order to increase the absorbency and water retention of absorbent products, a certain amount of superabsorbent resin is often added to the absorbent layer during the production of absorbent products, so that the body fluids can penetrate through the liquid-permeable layer. When the surface layer reaches the absorbent layer, the superabsorbent resin can quickly absorb the body fluid and lock it firmly, preventing the body fluid from returning to the liquid-permeable surface layer again. However, the super absorbent resin will rapidly expand to several times o...
