Abstract

The invention relates to the field of sanitation supplies and provides a preparation method of a composite core. The defect of a complex preparation technology of a composite core in the prior art isovercome. The method comprises the steps of preparation of a surface layer pure wood pulp layer, preparation of a middle mixing layer and preparation of a bottom layer pure wood pulp layer. The surface layer pure wood pulp layer, the middle mixing layer and the bottom layer pure wood pulp layer are formed on a core preparation machine at a time. The core preparation machine comprises a cotton suction mold wheel, a wood pulp feeding port is formed above the cotton suction mold wheel, and a formation bin is arranged between the wood pulp feeding port and the cotton suction mold wheel; a bin division plate (4) and a bin division plate (5) are arranged in the formation bin at intervals, a fixing rack for fixing the bin division plate (4) and the bin division plate (5) is arranged at the top ofthe formation bin, the formation bin is divided into a first formation bin area, a second formation bin area and a third formation bin area by the bin division plate (4) and the bin division plate (5), and a macromolecule water-absorbent resin discharging pipe is arranged above the second formation bin area.

Description

technical field [0001] The invention relates to the field of sanitary products, in particular to a preparation method of a composite core. Background technique [0002] Disposable hygiene products such as paper diapers and sanitary napkins are known in structure, and usually consist of a liquid-permeable surface layer, a liquid-impermeable bottom layer, and an absorbent core disposed between the liquid-permeable surface layer and the liquid-impermeable bottom layer. Some absorbent cores are generally composed of non-woven fabrics or toilet paper wrapped wood pulp and polymer water-absorbent resin. After absorbing water, the wood pulp is dispersed due to the expansion of the polymer water-absorbent resin, which weakens the diversion effect in the core and weakens the absorption effect, especially After repeated absorption, the effect is obviously weakened, and reverse osmosis is prone to occur. [0003] Chinese patent application No. 201710271358.1 discloses a composite core...
