Embodiment 1

[0037] A kind of preparation method of the breathable absorbent article of waist circumference, such as figure 1 , figure 2 , image 3 and Figure 4 shown, including the following steps:

[0038] 1), preparing the absorbent body and cutting it into individual absorbent bodies 100 separated from each other;

[0039] 2), preparing the clothing layer 200;

[0040] 3), rotating the absorber 100 by 90 degrees relative to its own conveying direction;

[0041] 4), the two ends of the absorber 100 along the length direction are respectively fixedly connected to the clothing layer 200;

[0042] 5), defined in the horizontal plane, the direction along which the clothing layer 200 is transported is the longitudinal direction, and the direction perpendicular to the longitudinal direction is the horizontal direction, and the clothing layer 200 and the absorbent body 100 on it are folded together along the horizontal direction, and The longitudinal sides of the absorbent body 100 are...

Embodiment 2

[0054] Such as Figure 5 As shown, compared with the first embodiment, the sealing glue 1 and the adhesive glue 2 in the step a) are realized by spraying spiral glue.

[0055] In the present invention, the adhesive glue 2 can be set in 2 to 4 lanes according to different sizes; at the same time, the cross-sectional area and radial height of each needle 51 can be adjusted and set according to actual needs, and the effect of punching and welding can be achieved. Can.

[0056] The invention sets the waistline structure as a double-layer non-woven fabric structure by improving the production process, adding elastics at the waistline between the two layers of non-woven fabrics, and opening air holes between the elastics, structurally ensuring that the clothing layer at the waistline is Excellent air permeability also makes the elastic evenly distributed, ensuring the uniformity of stretching at the waist and improving the wearing comfort;

[0057] Adopt the form of discontinuousl...

Abstract

The invention relates to the field of disposable hygienic products, in particular to a production method of an absorbent product with a breathable waistline. A clothing layer making method comprises the following steps: (a) defining that the circumferential length of the clothing layer, at a waist opening, of the absorbent product is 2L, conveying a first non-woven fabric in a continuous conveyingmode, applying a streak of sealing adhesive and two to four streaks of bonding adhesive on the two transverse sides of the upper surface of the first non-woven fabric respectively at an interval of the length L in the longitudinal direction, wherein the longitudinal length of the sealing adhesive is 30-50 mm, and the transverse width of the sealing adhesive is X; the streaks of bonding adhesive are uniformly arranged in the longitudinal direction of the clothing layer, the longitudinal length of each streak of bonding adhesive is 5-20 mm, and the transverse width of each streak of bonding adhesive is Y, and Y-X equals -10-10 mm. The production method is applied to the production of hygienic products, and the problem is solved that the waistlines of existing hygienic products are poor in air permeability.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a method for preparing waistline-permeable absorbent articles. Background technique [0002] With the improvement of people's living standards, there have been pull-up pants for the transition from diapers to ordinary underwear. Pull-up pants are an integral structure like underwear. Children can't pull them off and it's not easy to urinate outside. Because pull-up pants have Easy to carry, clean and hygienic, easy to wear and beautiful, so the use of pull-up pants for infants is becoming more and more extensive. [0003] For example, the Chinese invention patent application dated May 29, 2015 discloses the basic structure of pull-up pants, specifically a kind of high-absorbency baby pull-up pants, including surface structure, absorbent core structure, bottom layer structure, closure Structure and viscose structure, the surface layer structure includes a surface layer...
