Method for preparing ultra-thin rapid-absorbing absorbency article

Abstract

The invention relates to the field of sanitary articles, and provides a method for preparing an ultra-thin rapid-absorbing absorbency article high in liquid absorbing speed, not prone to fracture and good in breathability. The method comprises the following steps that firstly, an upper layer base material and a lower layer base material are prepared and combined; secondly, a lower wrapping layer is prepared, glue is applied to the lower wrapping layer, and the combined upper layer base material and lower layer base material are attached to the lower wrapping layer; thirdly, sap discharging spray guns are arranged above through holes of the composite base material and provided with nozzles, the nozzles are aligned with the through holes, the nozzles convey sap into the through holes, super-water-absorbent resin protruding blocks are formed, the height of the super-water-absorbent resin protruding blocks ranges from 2 mm to 30 mm, and an absorbing core wrapped by the lower wrapping layer is obtained; fourthly, glue is applied to the surface of the absorbing core wrapped by the lower wrapping layer, an upper wrapping layer is combined, and an absorbing body is obtained.

Description

technical field [0001] The invention relates to the field of sanitary products, in particular to a preparation method of an ultra-thin quick-absorbing absorbent product. Background technique [0002] Traditional disposable absorbent articles mainly include a liquid-permeable surface layer, an absorbent body and a liquid-impermeable bottom layer that are stacked sequentially from top to bottom. Provides a comfortable and dry feeling when in contact with the body, while allowing liquids to pass freely into the underlying absorbent body. The liquid impermeable bottom layer is used to keep the absorbed liquid in the absorbent body, thereby preventing the absorbed liquid from soiling the wearer pants. In order to increase the absorption capacity, the thickness of the absorber is usually increased in the existing absorbent articles, but increasing the thickness of the absorber will lead to a decrease in air permeability, an increase in cost, and the absorber is easy to break.

AI Technical Summary

Problems solved by technology

In order to increase the absorption capacity, the existing absorbent articles usually increase the thickness of the absorbent body, but increasing the thickness of the absorbent body will lead to reduced air permeability, increased cost, and easy breakage of the absorbent body

In order to improve air permeability, holes are usually drilled on the absorber, but in order to increase the absorption capacity, the thickness of the core must also be increased, which also requires a higher economic cost.

Correspondingly, the preparation method of the traditional absorbent article includes the preparation of the core body. The core body is usually made of a mixture of sap (super absorbent resin) and fluff pulp, which is adsorbed into the cavity of the mold wheel by negative pressure. The metal mesh is generally set horizontally, and the prepared core body is flat and integrated. The product is relatively ordinary, the liquid absorption speed is slow, and it is easy to break.
