Embodiment 1

[0040] refer to figure 1 Shown, a kind of preparation method of anti-side leakage trousers type diaper comprises the following steps:

[0041] 1) Preparation of liquid-permeable surface layer:

[0042] Unwind the pre-produced roll-shaped hydrophilic non-woven fabric 1 and convey it along the direction of the preparation process of trouser-type diapers. Define the extending direction of the conveying direction of the hydrophilic non-woven fabric as the longitudinal direction, along the width of the hydrophilic non-woven fabric The direction in which the direction extends is the transverse direction;

[0043] 2) Prepare absorbent core layer 11:

[0044] a. Molding an absorbent core 2 through a forming die wheel, and the absorbent core 2 is made of a bulky non-woven fabric with a polymer water-absorbing resin;

[0045] b. Cover the upper surface and the lower surface of the product in step a with toilet paper 3;

[0046] 3) Adhere the horizontal middle part of the hydrophilic...

Embodiment 2

[0066] refer to figure 1 and figure 2 As shown, the second embodiment is further improved on the basis of the first embodiment, and its difference from the first embodiment is that: in the step 4 and step 5, the left hydrophobic non-woven fabric 51 and the right hydrophobic non-woven fabric Spray glue on the opposite surface of the woven fabric 52 and near the PE film 4, so that when the product in step 3 is cut and adhered to the upper surface of the product in step j, the left hydrophobic non-woven fabric 51 and the right hydrophobic non-woven fabric 52 The upper spray glue part adheres to the lateral sides on the upper surface of the liquid-permeable surface layer, so that the connection between the left hydrophobic non-woven fabric 51 and the right hydrophobic non-woven fabric 52 and the liquid-permeable surface layer is firm, and can better cover Covering the lateral sides of the absorbent core layer 11, so as to enhance the anti-side leakage performance.

Abstract

The present invention relates to the field of disposable sanitary products, in particular to a method for preparing side leakage-proof trouser-type diapers, which mainly solves the problem of poor comfort on each side of the side-leakage-proof sides of trouser-type diapers in the prior art, and includes the following steps: Prepare the liquid-permeable surface layer; prepare the absorbent core layer: adhere the liquid-permeable surface layer to the absorbent core layer, and bend the lateral sides of the liquid-permeable surface layer downward to cover the horizontal two sides of the absorbent core layer. Side; preparation of liquid-impermeable bottom layer: the product of step 3 is adhered to the upper surface of the product of step j after cutting, and is located between the left and right hydrophobic non-woven fabrics; preparation of clothing layer: the product of step n The product is located between two adjacent absorbers and the trousers are cut out; the product in step 7 is folded along the central axis in the transverse direction, and welded in the transverse direction at the trousers; the product in step 8 is welded along the central axis of the weld Part cut into individual products to make pant diapers.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a preparation method of anti-side leakage trouser-type diapers. 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...
