A kind of preparation method of paper diaper core body

Abstract

The invention relates to the field of disposable hygiene products, in particular to a method for preparing a diaper core, which mainly solves the problem of low absorption efficiency of the diaper core in the prior art, and comprises the following steps: preparing an absorbing layer, a fluff pulp layer, The air-through non-woven fabric is compounded, creased, and cut to form an absorbent body, and its two sides are folded to form an absorbent core layer, and two sets of sutures are sewn side by side along the longitudinal direction of the front area, so that the second fold The free end of the first folded part, the free end of the first folded part, and the transverse middle part of the absorbent body are sewn and connected, and the absorbent core layer is folded twice to form a folded area, and the second absorbent body is formed by a forming die wheel, and cut into A single second absorbent block, the second absorbent block is compounded on the lower surface of the rear area of ​​the absorbent core layer and close to the folded area to form the core body of the diaper.

Description

A kind of preparation method of diaper core technical field [0001] The present invention relates to the field of disposable sanitary products, in particular to a preparation method of a paper diaper core. Background technique [0002] The core body of the diaper is the core part that guarantees the function of water absorption and water retention. After it absorbs water, moisture is easily accumulated in the water injection part. Due to the influence of gel retardation, the utilization rate of polymer water-absorbing materials is low, and the water-locking ability also has certain limitations. sex. At the same time, because the structure of this material is relatively loose, once it absorbs water, it will form lumps and faults. After movement and extrusion, it is often unavoidable. Avoid core deformation. In the prior art, by improving the way in which the polymer water-absorbing material is mixed with wood pulp, it is However, the core deformation cannot be effectiv...
