Problems solved by technology

[0004] However, sometimes babies loose stools in various positions, especially in a sitting position, the loose stools can easily go up from the back, and then overflow from the waist area, staining the underwear and making it difficult to clean
However, the existing structure of baby diapers does not have a structure that can be further tightened in time to reduce the probability of upward spillage of loose stools, and there is no relevant literature that gives the inspiration for the development of this technical concept.

Embodiment 1

[0031] like Figure 1-3 As shown, the present embodiment provides an elastic waist panel of a baby diaper, comprising a first sheet 10, a second sheet 20 and a plurality of elastic ribs sandwiched between the first sheet 10 and the second sheet 20 30 and a plurality of water-sensitive shape memory membranes 40.

[0032] In this embodiment, the first sheet 10 and the second sheet 20 are both non-woven structures. The raw material fiber of the non-woven fabric is not particularly limited, for example, it can be olefin-based such as polyethylene or polypropylene, synthetic fibers such as polyester-based and polyamide-based fibers, regenerated fibers such as rayon or cupro fibers, natural fibers such as cotton, etc. fibers, etc., or mixed fibers, conjugated fibers, and the like using two or more of them. In addition, the nonwoven fabric can be produced by any processing. As the processing method, well-known methods such as spunlace method, spunbond method, hot rolling method, m...

Embodiment 2

[0048] like Figure 4 As shown, this embodiment provides an elastic waist piece of a baby diaper. The difference between the second embodiment and the above-mentioned first embodiment is only that the second adhesive layer 31 on the elastic rib 30 is arranged on the elastic rib 30 On the wall surface, the water-sensitive shape memory membrane 40 is arranged in the first interval 101 and sandwiched between the elastic rib 30 and the second sheet 20; Adhesion, the third adhesive layer 32 is provided on the lower wall surface of the second rib portion of the elastic rib 30, and the second adhesive layer 31 is on the upper wall surface of the elastic rib 30. During the coating operation, the elastic rib 30 can be applied first. The lower wall is coated at intervals to form a third adhesive layer 32, and then the upper wall of the elastic rib 30 is coated at intervals to form a second adhesive layer 31; the second sheet 20 is in contact with each water-sensitive shape memory membra...

Embodiment 3

[0057] like Figure 5As shown, this embodiment provides an elastic waist piece of a baby diaper. The difference between this embodiment 3 and the above-mentioned first embodiment is only that part of the water-sensitive shape memory film 40 is sandwiched between the elastic rib 30 and the first sheet The part of the water-sensitive shape memory membrane 40 is set as the first membrane 41, and the remaining part of the water-sensitive shape memory membrane 40 is sandwiched between the elastic rib 30 and the second sheet 20. The remaining part of the water-sensitive shape memory membrane 40 is set as the second membrane 42 , and preferably, the first membrane 41 and the second membrane 42 are spaced from left to right. The second adhesive layer 31 on the elastic rib 30 corresponding to the first diaphragm 41 is provided on the lower wall surface of the elastic rib 30, and the second adhesive layer on the elastic rib 30 corresponding to the second diaphragm 42 The knot layer 31 ...

Abstract

The invention relates to an elastic waist sheet of a baby diaper, comprising a first sheet, a second sheet, a plurality of elastic ribs and a plurality of water-sensitive shape memory membranes. A plurality of first adhesive layers are coated at left and right intervals, each water-sensitive shape memory film is arranged in the first interval between two adjacent first adhesive layers in the central region, and a plurality of elastic ribs are respectively bonded to the first adhesive layers. The layers are combined, and each elastic rib is coated with a second adhesive layer facing the wall surface of the water-sensitive shape memory membrane, and the second sheet is bonded to the first sheet through the first adhesive layer and wraps the elastic rib and water-sensitive shape memory membranes. The present invention also provides a method for manufacturing the above elastic waist panel. The invention will not affect the normal contraction and stretching of the elastic tendons. When the loose stool of the baby ascends for some reason and penetrates between the first sheet and the second sheet, the water-sensitive shape memory film shrinks and deforms when wet. Pull the elastic tendons to tighten the waist and reduce the possibility of loose stools overflowing upwards.

Description

technical field [0001] The invention relates to the technical field of diapers, in particular to an elastic waist sheet of a baby diaper and a manufacturing method thereof. Background technique [0002] In order to improve the fit to the body, the outer body is formed into a laminated structure having a plurality of sheet layers, and various elastic elastic members are installed between the sheets in an extended state, wherein the following structure is suitable for the body. The fit is relatively high: in the waist area determined to be in the front-rear direction range corresponding to the side seal portion, or in the intermediate area between the front and rear waist areas, spaced in the front-rear direction and elongated in the width direction, respectively. In the state, an elongated elastic elastic member along the width direction is attached. [0003] A known stretchable elastic member for disposable diapers is formed by applying an adhesive between two layers of she...
