Description
Technical field
The utility model relates to disposable absorbent article fields, and a kind of water conservancy diversion absorptive core is especially arranged.
Background technique
In general, baby's absorbent article includes baby paper diaper, nappy, Tolaku etc., there is multilayer material composition,
Including inner surface material, absorbing material etc..As the improvement of people's living standards, due to baby paper diaper have it is easy to carry,
The advantages of clean hygiene, therefore, paper diaper for infant using more and more extensive.Baby's absorbent article increasingly be particular about comfortably with
Practical, the application of baby's absorbent article facilitates people and fosters baby.
More thick and heavy due to resulting in paper diaper using traditional technique, it is inconvenient to come to infant's active belt, and it is long when
Between use be easy to stick together, tomography, therefore be easy to be expressed to the crotch of infant, make troubles to infant's activity, while
The health care belt of infant is endangered, the healthy growth of infant is influenced.In order to which baby's dress is more comfortable, occur by bulky suction
Receive the case where material is to ultra-thin absorbent excessive material.But due to ultrathin products have the characteristics that it is lighter and thinner, more comfortable,
It is more and more welcomed by the people.
Ultrathin products currently on the market are multifarious, various in style, but due to the characteristic of ultra-thin absorbent core itself, because
This, has many defects.Such as, ultrathin products are resulted in using conventional technique and is easy side leakage, while longitudinal diffusion is poor, affects
The actual use performance of the absorptive core, and be easy to cause baby's erythema etc..
In order to improve defect existing for ultra-thin absorbent core, the investigative technique people of domestic disposable sanitary articles technical field
Member has made intensive studies the diffusion of ultra-thin absorbent core, guide performance, such as:
Notification number is that the patent of CN203244508U, CN103300975B each provide a kind of pectination multilayer absorbent core
Body, including the comb teeth-shaped structure inside ultra-thin multilayer absorbent core body and core, each layer of absorber layers are longitudinally arranged knot by several
The absorber item composition on fibrous structure plies is closed, apart has interval between absorber item, this is spaced on absorptive core and is formed
Longitudinal pectinate texture, can realize that paper diaper become more frivolous, while paper diaper absorb formation U-shaped solid knot after liquid
Structure, personal effect is more preferable, and prevents urine to two sides horizontal proliferation, preferably dredges urine, so that urine is toward longitudinal direction row
A possibility that walking and be absorbed, reducing side leakage prevents urine from oozing out from leg two sides.
The utility model patent that notification number is CN206822784U disclose a kind of absorptive core with trace line structure and
Paper diaper prepared therefrom, and the absorptive core with trace line structure is specifically disclosed, including from top to bottom successively fold and set surface layer
Non-woven fabrics, guide layer, the uptake zone by inner layer non-woven wraps and counterdie；The uptake zone is equipped with many places trace line structure, institute
Stating trace line is impression, cut mark or cutting, and the trace line includes at least one of straight line, camber line, folding line.And it specifically discloses
A kind of paper diaper for being made of above-mentioned absorptive core, the absorptive core of the utility model greatly improve local absorption rate, accelerate
Infiltration rate prevents core agglomeration deformation, applied to that can keep surface dry in paper diaper in a long time, to use
Person provides comfortable use environment.
Notification number is that the patent of invention of CN105919733A discloses a kind of absorption for having high-efficiency diversion and gas permeability
Core, including surface layer, bottom and absorbed layer, absorbed layer include the nonwoven layer being bonded with surface layer lower surface, in nonwoven layer
Uniform broadcasting has super absorbent resin；Surface layer is bonded to form composite layer with nonwoven layer, and composite layer is equipped with diversion channel slot, water conservancy diversion
Core is divided into muti-piece absorption region by groove；Composite layer is connect with bottom upper surface；Table on nonwoven layer lower surface and bottom
Uniform broadcasting has super absorbent resin between face.A kind of processing method is also provided simultaneously, non-woven fabrics can be reduced to greatest extent
Gelation degree increases
Soft comfortable degree improves sense of touch.The absorptive core is arranged in pairs or groups the SAP of different performance between layers, and core is in imbibition
After show apparent protrusion, have the advantages that soft comfortable, good permeability, imbibition diffusion are fast, small with skin contact area.
But no matter aforementioned publication uses the longitudinal side of absorptive core to be provided with pectinate texture, or is absorbing
Grooving or cut mark are set on core, although preceding solution can promote the longitudinal diffusion of urine to a certain extent, due to
The Super Absorbent Polymer Particles for constituting absorber item have the characteristics that large specific surface area, infiltration rate are fast, therefore, once urine stream
Super Absorbent Polymer Particles surface is touched, i.e., is stored by Super Absorbent Polymer Particles, meanwhile, Super Absorbent Polymer Particles absorb urine
After will expand, the high hydroscopic resin colloid after expansion will be got into, migrate to the comb teeth-shaped structure or grooving of fibrous structure plies
Or in cut mark, and the phenomenon that colloid surface is tacky, it is easy to appear colloid choking phenomenon, subsequent urine is caused to be difficult to spread apart again
Come.In order to improve problem of the existing technology, the utility model overcomes such technology to ask using a kind of special absorptive core
Topic.

Angle 10 between body and the longitudinal centre line of baffle is 50 ° -70 °, and such as 50 °, 60 ° or 70 °.The cuboid-type convex body
Height be less than or equal to the diversion trench along water conservancy diversion core thickness direction depth, top be arc surface, the arc surface
Both ends extend along cuboid-type convex body length direction, until connect with upper caldding layer or lower caldding layer and form continuous surface.This
Outside, in addition to cuboid-type convex body, it is also an option that the convex body of other shapes, such as oval convex body, diamond shape convex body.
The cross-sectional shape of the diversion trench of the present embodiment is rectangle, inverted trapezoidal, V-arrangement or U-shaped, but preferred U-shaped, the water conservancy diversion
The port length of slot is 1-15mm, preferably 3-6mm, width 1-5mm, preferably 3-4mm, and depth is the 20%- of water conservancy diversion core thickness
45%；The width of the convex body is 1-6mm.The open end shape of the diversion trench of the present embodiment is ellipse, parallelogram, water chestnut
Shape or rectangle.
The advantageous effects that the present embodiment is realized are as follows: diversion trench has the function of temporarily storing liquid, but also liquid
It can spread, permeate into absorptive core or in convex body along the circumferential side wall of dotted indent, so that liquid is quickly spread, improve liquid
The diffusion of body, water conservancy diversion rate, meanwhile, baffle increases absorptive core and absorbs wet strength and its dimensional stability after liquid, has
Effect reduces the problem of absorbed layer leads to infiltration, side leakage because of colloid blocking in the prior art.
