Embodiment 1

[0031] A high-absorbency diaper core body includes a lower core body 1 and an upper core body 2. The lower core body 1 includes a first fluffy cotton 12 containing a first polymer water-locking bead 14, and an upper core body 2 includes a second high The second fluffy cotton 22 with molecular lock water beads 24, the dosage of the first fluffy cotton 12 is 300 g / m², the dosage of the second fluffy cotton 22 is 200 g / m², and the size of the first fluffy cotton 12 is 40 *10 cm, the size of the second fluffy cotton 22 is 20*5 cm, the mass of a complete core is 14 grams, and the thickness of the middle absorbent part is 500 grams / square meter. The amount of fluffy cotton used in the core of the conventional diaper is 450 g / m2, and the mass of a complete core is 18 g. The core in this technical solution can reduce the raw material cost by 4 g compared with the core of the traditional technology, and The absorption rate of the middle part is higher, and at the same time, it makes the...

Embodiment 2

[0033] A high-absorbency diaper core body, comprising a lower core body 1 and an upper core body 2. The lower core body 1 comprises a first fluffy cotton 12 containing a first polymer water-locking bead 14, and the upper core body 2 is a plurality of longitudinally arranged and distributed The wood pulp absorbent block 3 on the lower core 1 has a strong absorption capacity of mixed polymer wood pulp, and the wood pulp has better skin affinity for infants and young children, and the raw material cost of wood pulp is lower than that of fluffy cotton. The diaper core using the wood pulp absorbent block 3 not only has better absorption capacity than the ordinary diaper core, but also saves the cost of raw materials, saves resources, and is environmentally friendly.

Embodiment 3

[0035] A high-absorbency diaper core body, comprising a lower core body 1 and an upper core body 2. The lower core body 1 comprises a first fluffy cotton 12 containing a first polymer water-locking bead 14, and the upper core body 2 is a wood pulp absorbent block Or it is a core containing the second fluffy cotton. The upper core 2 has two pieces, which are respectively arranged horizontally on the front half and the back half of the lower core 1. In the process of using diapers, the infants and young children have different postures. , The body fluid may penetrate forward or backward. The upper core 2 placed horizontally at the front and rear ends can prevent the body fluid from leaking at the front and rear ends and absorb the body fluid, thereby improving the absorption of the upper core and the middle area. rate.

Abstract

The invention discloses a high absorptivity diaper core. The core comprises a lower core, the lower core comprises first wood pulp dust-free paper, first fluffy cotton and first hydrophilic non-woven fabric which are pressed from top to bottom and formed, a first polymer layer is arranged in the first fluffy cotton in a clipped mode, the first polymer layer comprises first polymer water absorbent beads distributed evenly, the upper surface of the first hydrophilic non-woven fabric is provided with an upper core, the surface area of the upper core is 1 / 7 -2 / 3 of the surface area of the lower core, an adhesion layer is connected between the first hydrophilic non-woven fabric and the upper core, the upper core is adhered to the lower core, the upper core is smaller than the lower core, and therefore the thickness of the middle area of a diaper is increased, absorption quantity demanded of the middle portion of the core can be ensured, the thickness of the lower core can be reduced at the same time, the periphery of which the usage rate is low is light and thin, the permeability of the core is improved, and the usage amount of row materials of the core is saved, the middle portion of the core is centralized at the same time, and the absorption and utilization rate of the core can be improved.

Description

Technical field [0001] The invention relates to the technical field of sanitary products for infants and young children, in particular to a core body of high-absorption diapers. Background technique [0002] Diapers are disposable sanitary products that are used by infants and young children. The core of diapers is mainly used for absorption. The core mass of diapers is usually 18-20 grams per piece, but the cores of existing diapers have the same thickness everywhere. According to the structure of the human body, the front and rear ends and both sides of the diaper core are usually dry, because due to gravity, it is difficult for infants to discharge body fluids to be guided around the core by the diversion groove. The surrounding core is thicker, which affects air permeability, and also increases the cost of production materials, resulting in increased waste of resources and costs. [0003] The Chinese utility model patent "A double-layer absorbent core and paper diaper" with ap...
