Description
Technical field
The utility model is related to hygiene article sector, more particularly to a kind of paper diaper absorptive core and paper diaper.
Background technology
Paper diaper are a kind of conventional amenities.In general, paper diaper are made up of three major parts：Surface coating
Layer, absorptive core and base fabric.Surface coating layer is referred to as clad or water penetration top layer, and clad is close to the body of user
Body, can promote urine rapid osmotic and effectively prevent to bleed back, and urine pants top layer is kept dry and comfortable.Paper urine on domestic market
The clad of trousers is substantially nonwoven cloth cover, and Breathable nonwoven can lift the ventilative degree inside urine pants, and vapor can flow
Pass to beyond urine pants, in time discharge moisture and hot gas, effectively reduce the chance that diaper rash occurs, soft comfortable does not stimulate skin.Inhale
Receive core body and be referred to as absorbent core layer or absorber, the main function of absorptive core is can to capture and quickly absorb urine
Liquid, scattered urine can be diffused into it in whole sandwich layer by capillarity, finally absorb and storage of urine.Absorptive core one
As include the integument, lower adhesive layer, absorbent core layer, upper adhesive layer and the upper integument that set gradually from the bottom to top.Base fabric, be
The outermost structure of paper diaper, with impermeability, can prevent that the moisture in absorptive core from oozing out, therefore alternatively referred to as impermeable
Water borne base.
Requirement with people to paper diaper not to improving, for convenience he（She）Use, people require paper diaper not
But it is frivolous, also want that absorbability is good, diffusivity it is fast etc., therefore, the demand of manufacturer people in order that product is more fitted generally exists
Make an effort to lift frivolous property, absorbability and the diffusivity of paper diaper on the integuments of paper diaper, absorptive core.For example will parcel
Layer is replaced by more frivolous, more ventilative non-woven paper or non-woven fabrics.The thickness of absorptive core is for example reduced again, while increasing macromolecule
Water-absorbing resin（Super Absorbent Polymer, SAP）Consumption, make that absorptive core is more lightening, absorbability is more preferable.And
