Preparation method of low-back-osmosis absorption article

Abstract

The invention relates to the field of absorption articles, and particularly relates to a preparation method of a low-back-osmosis absorption article which is high in excretion liquid absorption speed, low in back osmosis amount and good in comfort. The preparation method comprises the following steps that 1), a liquid-permeable surface layer is prepared; 2), a flow guide layer is prepared; 3), an absorption core layer is prepared, wherein the absorption core layer comprises a first absorption core body, a tensile elastic piece and a second absorption core body which are sequentially stacked from top to bottom, and the tensile elastic piece adheres to the transverse middle of the lower surface of the first absorption core body and does not adhere to the upper surface of the second absorption core body; a, the tensile elastic piece is prepared; b, the first absorption core body is prepared; and c, the second absorption core body is prepared; 4), a liquid-impermeable bottom layer is prepared; and 5), the liquid-permeable surface layer, the flow guide layer, the absorption core layer and the liquid-impermeable bottom layer are sequentially compounded and then cut into single low-back-osmosis absorption article.

Description

technical field [0001] The invention relates to the field of absorbent articles, in particular to a preparation method for low-rewet absorbent articles. 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 existing absorbent articles usually increase the thickness of the absorbent body, but increasing the thickness of the absorbent body will result in reduced air permeability, increased cost, and easy breakage of the absorbent body; moreover, the abso...

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 result in reduced air permeability, increased cost, and easy breakage of the absorbent body; moreover, the absorbent body undergoes repeated urine absorption. Finally, its surface is often in a wet state, and it is difficult to keep the dryness of the liquid-permeable surface layer. At the same time, because of the wearer's activities, the absorbent article is squeezed, and the urine seeps back to the surface under the action of the squeeze force. Absorbing the surface of the surface layer not only causes a decrease in comfort, but also causes skin rashes after prolonged contact
