Forming method for ultra thin absorption core

Abstract

The invention relates to a forming method for an ultra-thin absorption core. The formed absorption core body comprises an upper absorption core layer, a middle absorption core layer and a lower absorption core layer which are stacked in sequence, the middle absorption core layer is wavy, and the wavy top end and the wavy bottom end of the middle absorption core layer are fixed to the upper absorption core layer and the lower absorption core layer through spot-breaking glue spraying; the middle absorption core layer is provided with a plurality of small holes; and the two sides of the lower absorption core layer are folded to the top of the upper absorption core layer to be fixed to form folded parts. The invention relates to the field of disposable hygienic products, when liquid enters the absorption core body, the upper absorption core layer and the lower absorption core layer can move relative to each other to form a buffer space, so that the middle absorption core layer forms a wave shape during production, the capacity of buffering and absorbing the liquid in the absorption core body is improved, the liquid is prevented from leaking, and the technical problems that the absorption core body is poor in flow guide effect and absorption capacity, so that liquid easily flows out are solved.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a method for forming an ultra-thin absorbent core. Background technique [0002] When the absorbent core of disposable sanitary products absorbs liquid, the middle part often absorbs more liquid, the two sides of the absorbent core absorb less liquid, the area utilization rate of the absorbent core is small, the absorption core has poor drainage effect, and the absorption capacity is poor. Enhance the absorption capacity of the middle part of the absorbent core. Generally, the absorbent core is produced thicker. However, when a large amount of liquid enters the disposable sanitary product instantly, the absorbent core is difficult to absorb a large amount of liquid in a short time, which may cause the liquid to flow out, and the thicker Absorbent cores not only have high production costs, but also take up a large space after packaging, and the packaging and transportat...
