Description

Leak protection trousers formula panty-shape diapers

Technical Field

The utility model relates to a disposable hygienic articles field especially relates to a leak protection trousers formula panty-shape diapers.

Background

The structure of the pants-type paper diaper is generally as follows: the absorbent comprises a liquid-permeable surface layer, an absorbent core layer and a liquid-impermeable bottom layer which are arranged in a laminated manner from top to bottom, the absorbent core layer is formed by combining fluffy non-woven fabrics and high-molecular water-absorbent resin or mixing wood pulp fibers and high-molecular water-absorbent resin and wrapping the fluffy non-woven fabrics with the high-molecular water-absorbent resin to form a block structure for absorbing and keeping human excretory fluid, the liquid-permeable surface layer consists of hydrophilic non-woven fabrics and hydrophobic non-woven fabrics which are fixedly arranged on the two transverse sides of the hydrophilic non-woven fabrics respectively, the hydrophilic non-woven fabrics are adhered on the upper surface of the absorbent core layer and are bent downwards to wrap the two transverse sides of the absorbent core layer, and are adhered on the liquid-impermeable bottom layer with the absorbent core layer for providing comfortable and dry feeling when contacting with the body, while allowing liquid to freely pass through into the underlying absorbent core, the liquid-impermeable back sheet is formed by combining a breathable water-impermeable film with a hydrophobic nonwoven fabric, and serves to retain the absorbed liquid in the absorbent core, thereby preventing the absorbed liquid from soiling the wearer's pants.

Usually the upper portion on preceding clothing layer and back clothing layer at trousers formula panty-shape diapers is provided with the waistline district, make trousers formula panty-shape diapers wear in-process inseparabler with the laminating of waistline, this waistline district is glue add along horizontal extension's rubber band by two-layer flexible material in the middle of usually and constitutes, be used for fixed rubber through the glue application, but its hardness that causes the lumbar region increases, the gas permeability descends simultaneously, make the travelling comfort in lumbar region poor, in addition in order to prevent the preceding of urine, the back leaks, need compound one deck leak protection layer, make the relatively poor lumbar region of travelling comfort add leak protection layer back originally, its thickness once more increases, cause the gas permeability poor, make the travelling comfort variation poor.

SUMMERY OF THE UTILITY MODEL
