Structure, discontinuous structure are fork type structure or the structure dissipated around by center being made of multiple circles.
Water absorption layer 4 is the mixture for the SAP that cellulose fiber peacekeeping is disposed therein.The cellulose fibre that can be used in this layer
It is including wood pulp, cotton, flax and moss well known in the art.Preferably, cellulose fibre is wood pulp.The suction of water absorption layer 4
Water ratio is 300 times, and with a thickness of 3 millimeters, SAP is in spherical, a diameter of 1 millimeter.
The material of bottom 5 is made of thin polymer film, but it can have and is made of the impermeable gas permeable material of liquid, such as
The nowoven membrane or microporous barrier or foam of water-proofing treatment.
Above layers can be bonded by hot melt adhesive, adhesive bonding, hot adhesion, ultrasonic bonds, radio frequency seal, it is mechanical
Curling etc. and other methods combination be made the utility model with hydrophobe capacity variation control liquid directional profile
Absorbent article.When in use, for liquid when entering absorbent article, the orderly direction flow distribution according to design first passes through table
Layer 1 enters cellular rubber layer 2, assembles in the through-hole that cellular rubber layer 2 is not coated with water repellent auxiliary agent, forms pressure with lower layer
Difference, driving liquid are flowed along vertical plane, and subsequently into close water repellent capacity variation functional layer 3, surface has relatively thin office
Portion water repellent surface and relatively thick water suction deformable material (high hydroscopic resin particle), flow along the horizontal plane wherein, when not repairing
After being decorated with the part water suction of water repellent auxiliary agent, it is destroyed by the surface water repellent ability that modification absorbs resin, hydrophilic ability is increased
By force, liquid is absorbed again as absorbing material, reach liquid and be first distributed to designated position in absorbent article, separate liquid outlet,
And stronger imbibition ability and capacity are maintained in the follow-up process.
The above is only the preferred embodiment of the utility model, is not intended to limit the utility model, it is noted that
For those skilled in the art, without deviating from the technical principle of the utility model, it can also do
Several improvements and modifications out, these improvements and modifications also should be regarded as the protection scope of the utility model.
