Abstract

The present invention relates to the field of disposable sanitary products, in particular to a preparation method of a novel leak-proof trouser-type diaper, which mainly solves the problem of poor comfort of the leak-proof trouser-type diaper in the prior art, and comprises the following steps: 1), preparing Liquid-permeable surface layer; 2), preparing an absorbent core layer; 3), preparing a liquid-impermeable bottom layer; 4), sequentially compounding and connecting the liquid-permeable surface layer, absorbent core layer and liquid-impermeable bottom layer; 5), Prepare the clothing layer: 6), cut the product of step 4 into individual absorbers; 7), combine the bottom nonwoven fabric at the front waist area and the back waist area with the elastic band along the adjacent blank area in the middle 8), the product in step 7 is located between two adjacent absorbers and cut out the trouser legs; 9), the product in step 8 is folded along the central axis of its transverse direction, and The trousers are welded in the transverse direction; 10), the product in step 9 is cut along the middle of the weld.

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...
