Problems solved by technology

However, due to the use of adhesives to fix the elastic parts, the waist will feel hard, making the formed elastic waist thicker and poor in air permeability. In addition, the wrinkles produced by the expansion and contraction of the elastic parts often cause the waist to not be in close contact with the skin. It is easy to draw red marks on the user's skin, especially the existing elastic parts (such as elastic bands) mostly have the problem of uneven elasticity, so it is very easy to cause damage to the baby's skin in the stretched state, causing children Suffering, which reduces customer satisfaction
[0004] In addition, there have also been cases of local sizing, dispensing, and applying elastic materials between the dispensing arrays. Although these solutions are helpful for reducing the hardness of the waistline, they still have high manufacturing costs. , low production efficiency, uneven elasticity

Embodiment 1

[0057] Such as Figures 1 to 5 As shown, an hourglass-shaped absorbent article 1 includes an outer covering structure 2 and an inner absorbent structure 3 .

[0058] The inner absorbent structure 3 includes a front sheet 31 , a back sheet 35 , an absorbent material 34 , a conductive layer 32 , a wrapping layer 33 and an anti-leakage side wrap 36 .

[0059] Wherein, the front sheet 31 is a liquid-permeable non-woven fabric material, and is arranged on the side close to the wearer's skin; the back sheet 35 can be selected from a liquid-impermeable film material, and is arranged on the side away from the wearer's skin; the absorbent material 34 and the covering The layers 33 together form an absorbent core, and the absorbent material 34 is covered by the covering layer 33 and is arranged between the front sheet 31 and the back sheet 35, and has a certain width in the horizontal direction X and extends along the longitudinal direction Y; the conductive layer 32 It is arranged bet...

Embodiment 2

[0091] Such as Figures 7 to 9 As shown, an hourglass-shaped absorbent article 1 includes an outer covering structure 2 and an inner absorbent structure 3 . Wherein, one end of the waist covering sheet 24 joined with the outer layer sheet 21 is fixed on the side of the outer layer sheet 21 where the folded segment 213 is away from the extension segment 214 . All the other are with embodiment 1.

Embodiment 3

[0093] Such as Figures 10 to 12 As shown, an hourglass-shaped absorbent article 1 includes an outer covering structure 2 and an inner absorbent structure 3 . Different from Embodiments 1 to 2, the number of first elastic components on the outer layer sheet 21 of this embodiment is slightly less than the number of first elastic components on the outer layer sheet 21 in Embodiments 1 to 2.

[0094] The outer layer sheet 21 is folded along the folding line FL which coincides with the edge of the first elastic member weaving region H on the side close to the third non-elastic region J. The wrapping section 213 extends to the crotch region B along the front waist region A and the rear waist region C, thereby forming a barrier structure 211a that prevents bodily fluids from leaking from the front abdomen and the back back. Since the outer sheet 21 itself is liquid-tight Therefore, the barrier structure 211a can completely replace the waist covering sheet 24. It can be seen that th...

Abstract

The invention discloses a method for producing absorptivity products. The method includes the following working procedures that a, arc leg-circumference elastic parts corresponding to leg openings are clamped between inner sheets and outer sheets; b, the portions, joined with inner absorption structures, of the leg-circumference elastic parts in stacking bodies are fused; c, the inner absorption structures are produced; d, the inner absorption structures are arranged between first elastic parts, corresponding to the front waistline areas and the back waistline areas of the absorptivity products, cross the two sides of the stacking bodies in the width direction. According to the method, compared with the prior art, the technological process is simplified, a large amount of hot melt adhesive is saved, and the production cost is reduced; meanwhile, improved outer wrapping structures have the better breathability and the better attachment degree on the front-back waistline areas and skin, and the practical requirements of consumers are met; the method has the advantages of being even in elasticity, good in attachment degree, soft, breathable, simple in structure and low in production cost.

Description

technical field [0001] The invention belongs to the field of sanitary product processing, and in particular relates to a manufacturing method of an hourglass-shaped absorbent product. Background technique [0002] There are known conventional absorbent articles comprising both side sheets for preventing side leakage of liquid, an absorbent main body for absorbing and retaining liquid, and a back sheet for preventing liquid penetration. In order to enhance the fit of absorbent articles to the body, there has been a technical solution to apply elastic bodies to the ventral and back side parts of the absorbent main body of the product formed by the two side sheets, the absorbent main body, and the back sheet. According to the forming method of the back sheet, it can be roughly divided into two types, namely: three-piece panty type diapers with the aforementioned absorbent main body, front waist panel, and rear waist panel; A two-piece pant-type diaper with a functional outer c...
