Embodiment 1

[0042] as attached figure 1 , figure 2 and image 3As shown, the baby diaper 1 of the present embodiment includes a liquid-permeable top layer 3, a liquid-permeable guide layer 4 and a liquid-impermeable bottom layer 10, and is arranged on the liquid-permeable top layer 3 and the liquid-impermeable bottom layer 10. The absorbent core 5 between the two sides of the absorbent core 5 is provided with three-dimensional guards respectively, and the three-dimensional guards include a left three-dimensional guard 22 and a right three-dimensional guard 21, each of which includes a The base part, the free part connected to the base part and located at the upper end of the base part, and the telescopic part connected to the free part and located at the upper end of the free part. The three-dimensional protective enclosures 21 are respectively elastically stretchable in the longitudinal direction, and the layers are glued and connected by a hot melt adhesive layer. The liquid-imperme...

Embodiment 2

[0053] The difference between this example and Example 1 is that this example uses a PE breathable film layer as the water-repellent layer, its square gram weight is 8g, and the air permeability is 3600g / cm 2 ·24h.

[0054] as attached figure 2 , image 3 As shown, the multiple side-leakage-preventing three-dimensional protective enclosures (left three-dimensional enclosure 22, right three-dimensional enclosure 21) of this embodiment are implemented by the following implementations:

[0055] 1) The SMS spunbond non-woven fabric or SMMS spunbond non-woven fabric with a square gram weight of 8g, wherein the mass percentage of the meltblown layer (ie, the M layer or the MM layer) is 16%, and the adhesive is formed after bending inward. The inner layer of the meltblown nonwoven fabric and the outer layer of the spunbond meltblown nonwoven fabric, wherein the inner layer of the meltblown nonwoven fabric is used as a hydrophobic layer, and the outer layer of the spunbonded meltbl...

Embodiment 3

[0061] This embodiment provides a method for preparing a disposable absorbent article with multiple side-leakage-proof three-dimensional guards, wherein the absorbent core, the liquid-impermeable bottom layer, the closure system (left and right waist tape, front waist tape, elastic waist), and each structure The method for layer composite connection is prepared according to the existing methods and steps, and the preparation method is familiar to those skilled in the art. The front waist patch is joined to the liquid-impermeable bottom layer, and the elastic waistband of the leg is compounded in the liquid-impermeable bottom layer. The position of the lateral inner side of the waist sticker. Another example: The continuous material that is compositely connected with each structural layer passes through a pair of flattening guide rollers during the transmission process, so that the continuous material is unfolded and flattened in the transverse direction, and then the waist is ...

Abstract

The invention relates to a method for preparing a disposable absorbent product with a multiple side-leakage-proof solid shield. The invention is characterized in that the preparation of a solid shieldcomposite sheet includes the following steps: Step 1, spraying glue on a nonwoven fabric sheet corresponding to the relevant position for connecting a water-repellent sheet; Step 2, connecting the water-repellent sheet onto the nonwoven fabric sheet through an adhesive layer; Step 3, slitting the nonwoven fabric sheet; Step 4, spraying glue on an elastic rubber band to glue and connect lateral sides of the water-repellent sheet; Step 5, spraying glue on the water-repellent sheet; Step 6, adopting a folding device to respectively form a water-repellent sheet as an intermediate layer and left and right solid shield composite sheets with a three-layer composite structure; and Step 7, respectively connecting the left solid shield composite sheet and the right solid shield composite sheet to two lateral sides of a liquid-permeable top layer through an adhesive layer to further form the multiple side-leakage-proof solid shield.

Description

technical field [0001] The present invention relates to the field of disposable absorbent articles, in particular to a method for preparing a disposable absorbent article with multiple side-leakage-proof three-dimensional guards. Background technique [0002] Generally speaking, baby absorbent products, including baby diapers, diapers, pull-off pants, etc., are composed of multiple layers of materials, including inner surface materials, absorbent materials, and the like. With the improvement of people's living standards, the application of baby diapers is becoming more and more extensive due to the advantages of convenient carrying and cleanliness. Baby absorbent products are more and more comfortable and practical, and the application of baby absorbent products is convenient for people to raise babies. [0003] Due to the defects in the structural design, the traditional diapers are more comfortable to wear, which generally leads to poor leakage prevention effect. Therefo...
