Method for producing absorptivity products

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...

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
