Side leakage prevention structure for diaper and making method of side leakage prevention structure

Abstract

The invention discloses a side leakage prevention structure for a diaper. The side leakage prevention structure for the diaper comprises two non-woven fabrics, PE films and rubber band layers, whereineach PE film adheres to one side of the corresponding non-woven fabric in a fusion manner; each rubber band layer adheres to the other side of the corresponding non-woven fabric in a fusion manner; the PE films and the rubber band layers are arranged on two sides of the peripheries of the two non-woven fabrics; and adjacent surfaces of the two non-woven fabrics adhere to each other and are fixedthrough fusion of the two PE films. The breathable PE films are added between the two layers of composite SMS non-woven fabrics, have a waterproof function, are high in physical property, and are notdamaged easily, and breathability is ensured when the problem of side leakage of the diaper is solved. In the aspect of the structure, the water-repellent SS non-woven fabrics and the SMS non-woven fabrics coat rubber bands through hot melt adhesive to form a conventional three-dimensional protective structure, the breathable PE films on the outer sides and the non-woven fabrics on the bottom layer are coated through adhesive spraying and adhere to each other through folding plates to form the external friction side leakage prevention structure, and therefore, shortcomings in the prior art areovercome effectively.

Description

technical field [0001] The invention relates to the technical field of diapers, in particular to a side leakage prevention structure of diapers and a manufacturing method thereof. Background technique [0002] The anti-side leakage structure of conventional diapers is a two-layer structure that simply uses water-repellent SMS non-woven fabrics and glue-sprayed compound elastics. However, diapers in the prior art still have many deficiencies in the actual application process, such as: [0003] In the prior art, consumers will use the diapers for a long time when the baby is using them, and the leak-proof structure of the general diapers will be in contact with urine for a long time, and the baby will move around for a long time, rubbing the SMS non-woven fabric , will cause damage, affect the water-repellent effect, reduce the hydrostatic pressure performance of the SMS non-woven fabric, and cause side leakage of excreta, so it cannot meet the needs of the prior art. Conten...

Problems solved by technology

[0003] In the prior art, consumers will use the diapers for a long time when the baby is using them, and the leak-proof structure of the general diapers will be in contact with urine for a long time, and the baby will move around for a long time, rubbing the SMS non-woven fabric , will cause damage, affect the water-repellent effect, and the hydrostatic pressure performance of SMS non-woven fabric will decrease, which will cause side leakage of excrement, so it cannot meet the needs of existing technologies
