Absorbent article capable of reducing conglomeration

Technical Field

The utility model relates to a disposable hygienic articles field, concretely relates to can reduce conglomeration's absorption article.

Background

Disposable absorbent articles such as diapers, adult incontinence articles, sanitary napkins and the like, the basic structure mainly comprises a liquid-permeable surface layer, an absorber and a liquid-impermeable bottom layer which are sequentially laminated from top to bottom, the absorber is used for absorbing and keeping human excretory fluid such as urine and menstrual blood, the liquid-permeable surface layer is used for providing comfortable and dry feeling when contacting with the body, meanwhile, the liquid is allowed to freely pass through and enter the absorber at the lower layer, and the liquid-impermeable bottom layer is used for keeping the absorbed liquid in the absorber, thereby preventing the absorbed liquid from dirtying the trousers of a wearer.

In the prior art, if the absorption capacity of an absorption article needs to be increased, the main approach is to increase the thickness or area of an absorption material in an absorption body, but the structure not only causes the increase of the raw material cost in the production cost, but also is easy to generate the phenomena of agglomeration and caking after the thickness or area is increased, so that the fracture phenomenon caused by the agglomeration is caused, and the structure is not stable enough.

As described in chinese patent CN201420627998.3, a novel baby diaper comprises a main body, wherein the main body comprises a front waist, an absorption layer and a rear waist, the absorption layer is disposed in the middle of the main body, the rear waist is disposed at the rear end of the main body, the left and right sides of the main body are both provided with edge leakage prevention edges, the absorption layer mainly comprises a strength absorption layer penetrating the entire length of the absorption layer, and the strength absorption layer is formed by alternately weaving elastic absorption beads and cotton fibers; the side leakage preventing edge comprises a first breathable side leakage preventing edge and a second breathable side leakage preventing edge, the first side leakage preventing edge is arranged on one side close to the inner layer of the absorption layer, a lace in contact with the skin of the baby is arranged on the upper side of the first side leakage preventing edge, a rubber band is arranged below the lace, the second side leakage preventing edge is arranged on the outer side of the first side leakage preventing edge, and a rubber band is arranged above the second side leakage preventing edge; the left side and the right side of the back waist are both provided with a non-adhesive waist tape. In the technical scheme, the strength absorbing layer penetrating through the whole length of the trousers body is mainly formed by alternately weaving elastic absorbing beads and cotton fibers, so that the paper diaper has super-strong shaping property after absorbing urine, and the phenomenon that the absorbing layer of the paper diaper is agglomerated and deformed after absorbing urine is effectively prevented. However, this solution cannot cope with a large amount of liquid.
