Abstract

The invention relates to the field of disposable sanitary articles, in particular to a preparation method of a novel leakage-proof pant-type paper diaper. The method mainly solves the problem of poorcomfort of leakage-proof pant-type paper diapers in the prior art. The method comprises the following steps: 1) preparing a liquid-permeable surface layer; 2) preparing an absorption core layer; 3) preparing a liquid-impermeable bottom layer; 4) sequentially compounding and connecting the liquid-permeable surface layer, the absorption core layer and the liquid-impermeable bottom layer; 5) preparing a clothing layer; 6) cutting a product in the step 4) into single absorption bodies; 7) folding the bottom non-woven fabric at the front waist region and the back waist region upwards along the boundary of adjacent blank region and rubber band region at the middle part of the non-woven fabric; 8) cutting trouser legs on the product in the step 7) and between two adjacent absorption bodies; 9) folding the product in step 8) along the central axis in the transverse direction, and welding the product in the transverse direction at the trouser legs; and 10) cutting the product in the step 9) along the middle part of the welding part of the product.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a preparation method of a novel leak-proof trouser-type diaper. Background technique [0002] The structure of pants-type diapers is generally: an absorbent body and a clothing layer compounded on its outside. The upper and lower ends of the clothing layer are turned over and contacted, and the two ends are welded and connected to form a pants-type diaper. The absorbent body is arranged from top to bottom. It includes a liquid-permeable surface layer, an absorbent core layer, and a liquid-impermeable bottom layer in sequence. The absorbent core layer is made of a fluffy non-woven fabric combined with a polymer water-absorbent resin or wood pulp fibers and a polymer water-absorbent resin. Wrapped in non-woven fabric to form a block-like structure for absorbing and retaining human excretion, the liquid-permeable surface layer is composed of hydrophilic non-woven fabric a...
