Problems solved by technology

Because the wood pulp, fluff pulp, paper pulp and other inner materials of the absorbent core layer are distributed in a loose form, the thickness of the product is greatly increased, which affects the air permeability and comfort of the product, especially after it absorbs liquid and is squeezed, The inner material of the absorbent core layer is very easy to lump, and the absorbent core layer is broken, which affects the timely absorption of urine, and it is uncomfortable to wear on the body due to the large difference in local thickness
The absorbent core layer is made of wood pulp, fluff pulp, paper pulp and other water-absorbing materials mixed with polymer water-absorbing resin. Since the polymer water-absorbing resin is simply mixed with wood pulp, fluff pulp, paper pulp and other materials, the distribution uniformity is relatively high. Poor, and the polymer water-absorbent resin cannot be fixed on the absorbent core layer, so the distribution of the polymer water-absorbent resin in this diaper product is uneven, and the product has poor urine absorption effect

Embodiment 1

[0019] Such as figure 1 , figure 2 , image 3 As shown, the paper diaper of the present invention is composed of a water-permeable non-woven inner cover layer 1, a water-impermeable leak-proof outer cover layer 3, an absorbent core layer 2, and an enclosing connector 4, with a thickness of 1.8 mm to 2.2 mm, wherein the water-permeable A flow-guiding layer 5 is provided between the non-woven inner cover layer 1 and the absorbent core layer 2. The absorbent core layer 2 is a layered body in which a polymer water-absorbing resin layer is sandwiched between the spacer layers of dust-free paper, and each layer is connected along the periphery. Composed of connections, the absorbent core layer 2 is a seven-layer cross-laminated composite material body, followed by the uppermost layer of dust-free paper 21a, polymer water-absorbing resin layer 22a, dust-free paper 21b, polymer water-absorbing resin layer 22b, and dust-free paper 21c , Polymer absorbent resin layer 22c, dust-free p...

Embodiment 2

[0024] Such as Figure 4 , Figure 5 As shown in , the paper diaper of the present invention is composed of a water-permeable non-woven inner cover layer 1, an impermeable leak-proof outer cover layer 3, an absorbent core layer 2, and a surrounding connector 4, and the thickness is 1.5 mm to 1.9 mm. , wherein a flow-guiding layer 5 is provided between the water-permeable non-woven inner cover layer 1 and the absorbent core layer 2, and the absorbent core layer 2 is laminated with a polymer water-absorbent resin layer and a mixed layer composed of wood fiber and polymer water-absorbent resin A ten-layer cross-laminated composite material body with small white paper sandwiched and covered with small white paper, followed by the uppermost layer of small white paper 21a, polymer water-absorbent resin layer 22a, made of wood fiber and polymer water-absorbent resin. Composed of mixed layer 23a, small white paper 21b, polymer water-absorbing resin layer 22b, mixed layer 23b composed...

Embodiment 3

[0028] Such as Image 6 , Figure 7 As shown, the paper diaper of the present invention is composed of a water-permeable non-woven inner cover layer 1, an impermeable leak-proof outer cover layer 3, an absorbent core layer 2, and a surrounding connector 4, and the thickness is 1.7 mm to 2.0 mm. A functional layer 6 with antibacterial effect and a flow guide layer 5 are sequentially arranged between the inner cover layer 1 of the water-permeable non-woven fabric and the absorbent core layer 2, and the absorbent core layer 2 is composed of polymer water-absorbing resin layers 22a, 22b, 22c and non-woven fabrics. 21b, 21c are stacked alternately at intervals and covered with non-woven fabrics 21a and 21d, which is a seven-layer composite material body, and the distribution amount of polymer water-absorbing resin is 100g / m 2 , is heat-sealed on the non-woven fabric. The functional layer 6 with antibacterial effect is the bearing layer of the bacteriostatic composition known to t...

Abstract

The invention relates to a paper diaper, comprising a permeable non-woven fabric inner covering layer, a watertight leak-proof outer covering layer, an absorbing core layer and a connecting piece surrounding in a trousers shape, wherein the absorbing core layer is formed by multi-layer compound materials, dust-free papers or small white papers or a macromolecule absorbing material layer clipped among non-woven fabrics formed by laminating the macromolecule absorbing material layer and the dust-free papers or small white papers or the non-woven fabric layer and covering the dust-free papers or small white papers or the non-woven fabrics; or the absorbing core layer is formed by blending the macromolecule absorbing material layer and pulp fibers and macromolecule materials and covering the dust-free papers or small white papers or the non-woven fabrics. The absorbing core layer abandons wood pulp, fluff pulp and paper pulp; when ensuring the absorbing capacity, the product thickness is greatly reduced and the using comfort is improved. The macromolecule absorbing material layer is clipped among paper spacing layers; the local collected uniform thickness caused by the free flowing of thicker macromolecule absorbing material layer, even local loss is avoided; urine is easily discharged and permeated; the urine delivery and diffusion blocked by the quickly expanded upper-layer macromolecule absorbing material layer, which contacts with the urine for a long time, is reduced; the absorbing effect of the macromolecule absorbing material is used furthest; and the function of locking urine is realized.

Description

technical field [0001] The invention relates to sanitary care articles for infants and adults, in particular to a paper diaper. Background technique [0002] With the development of the economy and the acceleration of people's life rhythm, in the health care products for infants and adults, a disposable diaper and a diaper composed of a surface covering layer, an absorbent core layer and a base cloth are characterized by their lightness, The convenience and no-wash advantage quickly replaced traditional cotton diapers. [0003] At present, the surface coating layer of commercially available diapers and diapers is made of non-woven fabric or cotton-like non-woven fabric, the base fabric is PE film or breathable PE film, and the absorbent core layer is mostly made of wood pulp, fluff pulp, paper pulp, etc. The water-absorbing material is made of wood pulp, fluff pulp, paper pulp and other water-absorbing materials mixed with polymer water-absorbing resin, and these inner mate...
