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.
