Description

PANTY-TYPE DIAPER PREVENTING PENETRATION/SIDE LEAKAGE AND APPARATUS FOR MANUFACTURING THEREOF

The present invention relates to the field of diaper products for use by infants or adults, and more particularly, to a panty-type diaper preventing side leakage and an apparatus for manufacturing the same.

Currently, as diapers commonly used in the market, there are one-piece diapers for infants or adults, training pants (triangle) and one-piece pants (shorts), all of which have an outer layer, an inner layer, and An absorbent core is provided between the outer layer and the inner layer, and a PE film layer is provided between the outer layer and the absorbent core. In the diaper, side leakage preventing edge strips are respectively installed on the outer surface side of the inner layer corresponding to the two side sides along the longitudinal direction of the absorbent core, and the side leakage preventing edge strip is fixedly connected to one side, and The other side is a free side, and elastic ribs are provided along the longitudinal direction, the free side edges of the side leakage prevention edge strip are oppositely arranged, and both ends are fixed to the inner layer, and the elastic ribs contract the diaper when in use. The effect of preventing side leakage can be achieved by three-dimensionally fitting the side leakage prevention edge strip to the infant's thigh. In addition, the side leakage-proof edge strip is usually made of non-woven fabric, which has a certain very short intermittent blocking effect, but cannot actually prevent penetration. A side leak is usually seen when the infant lies on his side. Although most of the existing diapers claim to have side leakage protection, in reality, they often cannot pass the side leakage test when lying on their side. This is because, when lying on your side, urine flows to the side and is not absorbed in the absorbent core in a timely manner, so the unabsorbed urine will seep out of the side leak-proof edge strip. Therefore, it is necessary to improve the problem of three-dimensional side leakage prevention of the diaper.

An object of the present invention is to provide a panty-type diaper preventing penetration/side leakage, which can improve the side leakage problem, and an apparatus for manufacturing the same.
