Description

A disposable absorbent article

technical field

The present invention relates to disposable absorbent articles, and more particularly to disposable absorbent articles having improved construction.

Background technique

In the field of disposable absorbent articles, such as sanitary napkins and light incontinence products, typically include a liquid-permeable topsheet material, a liquid-impermeable backsheet material, and an absorbent layer positioned between the topsheet and backsheet materials. Disposable absorbent articles are generally used to absorb and contain the wearer's excrement such as menstrual blood, urine and other excrement. The absorbent layer is used to collect and store the wearer's excrement. The absorbent layer usually comprises a fibrous batt or web of separated fibers, loose and fluffed hydrophilic cellulose fibers. The absorbent layer may also comprise microparticles, granules, flakes or fiber.

Disposable absorbent articles have developed from the straight type to the structure with side wings. Typically, the wings project laterally from the central absorbent member and are folded around the crotch edge of the wearer's panties. In this way, the two flaps are positioned between the crotch edge of the wearer's panties and the wearer's thighs. Typically, the two flaps have fastening means for fastening them to the underside of the wearer's panties. The wings serve at least two functions. First, the flaps prevent excrement from soiling the edges of the wearer's panties; second, especially when the wings are attached to the bottom of the wearer's panties, the wings secure the napkin and prevent it from slipping in place. Move out of position.

While the wings greatly improve the use of the disposable absorbent article, the wings of the disposable absorbent article may also interfere with the location of the disposable absorbent article being adhered to the user's panties. Usually, the flaps of disposable absorbent articles are bonded to the relatively narrow area of the crotch of the user's underwear, and the front and rear positions of the body cannot be adjusted freely according to the needs of consumers.

Before use, the self-adhesive adhesive 28 can be temporarily coated with release paper or non-woven fabric of silicone oil. cover. As shown in FIG. 1 or FIG. 3 , embossing 12 and a pair of longitudinally extending flow guide grooves 11 are provided on the liquid-permeable surface layer of the main absorbent assembly. The liquid-permeable facing material 21 is preferably compliant, soft-feeling and non-irritating to the wearer's skin. Suitable liquid-permeable surface layer material 21 can be made of many materials, such as spun-bonded non-woven fabric, spunlace non-woven fabric, air-through non-woven fabric, heat-bonded non-woven fabric, and porous formed film. The liquid-impermeable backsheet material 23 is composed of a flexible material that is impermeable to liquids (such as menses and/or urine) to prevent contact with and secretions from the absorbent core 22 where liquids may be squeezed out of the absorbent core 22 and may accidentally overflow the absorbent core. Contaminates the wearer's underwear. The liquid-impermeable bottom layer 23 can be made of woven or non-woven fibrous material that has been treated to be liquid-impermeable, a polymer film such as a thermoplastic film of polyethylene or polypropylene, or a composite material such as a breathable film combined with a non-woven fabric. In addition, the liquid-impermeable back layer 23 may allow moisture to escape from the absorbent core (ie, breathe) while also preventing exudates from passing through the liquid-impermeable back layer 23 .

The absorbent core 22 is used to collect and store body waste. The absorbent core can generally be made of any material that is soft, compliant, comfortable, non-irritating to the wearer's skin, and capable of absorbing and retaining body exudates.
