Embodiment Construction

[0024] In order to more clearly illustrate the features and effects of the present invention, the following will be described in detail in conjunction with the accompanying drawings. As a specific limitation of the protection scope of the present invention.

[0025] figure 1 It is a schematic cross-sectional view of the absorbent core of the diaper of the present invention. Such as figure 1 As shown, the present invention provides an absorbent core for diapers. The absorbent core 1 comprises from top to bottom: an upper core layer 10, a first polymer layer 20, a fluffy cotton 30, a second polymer layer 40 and a core The underbody layer 50 is characterized in that grooves 25 and 45 not containing polymer absorbing particles are respectively formed in the first polymer layer 20 and the second polymer layer 40 .

[0026] The upper layer of the core and the lower layer of the core can be made of materials such as spunlace non-woven fabric, dust-free paper, toilet paper or wet-s...

Abstract

The invention relates to a paper diaper absorption core body. The paper diaper absorption core body sequentially comprises a core body upper layer, a first macromolecule layer, fluffy cotton, a second macromolecule layer and a core body lower layer from top to bottom, and is characterized in that grooves without macromolecule absorption particles are formed in the first macromolecule layer and the second macromolecule layer correspondingly. The paper diaper absorption core body has the advantages of being high in instant absorption effect and capable of effectively preventing side leakage, the problems that an existing paper diaper absorption core body is prone to breakage, poor in diffusivity, prone to side leakage and the like are solved, the gel blocking phenomenon is reduced, and the utilization rate of the macromolecule absorption particles is increased. The invention further provides a preparation method of the paper diaper absorption core body.

Description

technical field [0001] The invention relates to a paper diaper absorbent core and a preparation method thereof, belonging to the field of sanitary care products. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, more and more parents choose to use paper diapers instead of traditional diapers. Diapers are disposable sanitary products for infants and young children composed of non-woven fabrics and absorbent cores. They are mainly used to absorb infant urine and block infant feces. The main part that absorbs urine in diapers is the absorbent core, which is one of the main materials for making disposable sanitary products such as diapers, sanitary napkins, and panty liners. [0003] The fluff pulp core used in the early days is mainly composed of superabsorbent resin (SAP) particles dispersed in fluff pulp fibers. This kind of core is widely used in European and American countries. The presence of flu...
