Description
Technical field
The present invention relates to hygiene article sectors, more particularly, to a kind of paper diaper ventilated membrane and preparation method thereof.
Background technique
Paper diaper are a kind of common amenities of baby.In general, paper diaper are made of three major parts: surface
Clad, absorbent core layer and base fabric.Surface coating layer is referred to as clad.Absorbent core layer is referred to as absorptive core,
Or absorber.Clad is close to the body of baby, can promote urine rapid osmotic and effectively prevent to bleed back, make urine pants surface layer
Keep dry and comfortable.The clad of paper diaper on domestic market is substantially nonwoven cloth cover, and Breathable nonwoven can promote urine
Ventilative degree inside trousers, vapor can be circulated to other than urine pants, and moisture and hot gas are discharged in time, effectively reduces diaper rash
Chance, soft comfortable do not stimulate skin.Absorbent core layer is referred to as absorptive core.The main function of absorbent core layer is can
It captures and quickly absorbs urine, dispersion urine or it can be diffused into entire sandwich layer through capillary action, finally absorb and store up
Deposit urine.The absorbent core layer of paper diaper is mainly by pure wood pulp (Time of Fluff Slurry) and high hydroscopic resin (SAP) structure on domestic market
At layer structure.Base fabric is the outermost structure of paper diaper, has impermeability, can prevent the moisture in absorbent core layer
Exudation.The base fabric of external many paper diaper is using feeling more comfortable non-woven fabrics, but due on the high side, domestic market
Paper diaper base fabric be still mainly made of PE film.
Through market survey, the factors such as gas permeability, water imbibition, comfort, dry-ness, safety are that mothers choose paper diaper
When the five big principal elements that consider, wherein gas permeability is particularly important.It is damp and hot ring inside paper diaper when due to there is urine generation
Border, so-called gas permeability is practical to refer to water vapor permeability, can be indicated with water vapour transit dose (g/cm is for 24 hours), while can also make
It is indicated with unit area air permeation amount (CFM).
The newest structure of paper diaper is broadly divided into surface layer at present, wink inhales guide layer, absorbent core layer, counterdie and other functional groups
Part.Paper diaper counterdie available on the market generally uses PP microporous barrier or Nonwovens PE composite membrane, (minimum using water droplet
10 μm of fogdrop diameter) and water vapour molecule (diameter 0.4nm) diameter difference, realize water droplet cannot penetrate and water vapour molecule
It can penetrate, achieve the effect that waterproof and breathable.Paper diaper counterdie is the major influence factors of paper diaper gas permeability, is directly affected whole
The permeability of a paper diaper, to influence comfort when infant wears paper diaper.
Current market sales of paper diaper mainly stretch microporous membrane using PP or PE to realize paper diaper counterdie
Waterproof and breathable function, but PP PE microporous membrane is difficult to meet very high waterproofness and good gas permeability simultaneously.At present
The best high-end paper diaper of several moneys are sold in the market is all made of the waterproof and breathable function that PP or PE microporous membrane realizes paper diaper,
In every money paper diaper counterdie tested by gas permeability and water pressure resistance, maximum bears hydraulic pressure and is no more than 1600mmH2O, gas permeability are best
Also it is no more than 0.1CFM；In fact only when the gas permeability of counterdie is met or exceeded in the case of 0.5CFM2 or moisture vapor amount
Reach 8000g/cm24h just and can guarantee the good gas permeability of paper diaper.According to routine use situation, commercial type at present
After absorbent core layer in gas-permeable paper urine pants fully absorbs urine, under sitting posture state, urine can seep baby through counterdie
Thoroughly to making trousers dirty on trousers.Therefore, a kind of good paper diaper counterdie, the permeability that not only met will also meet
Prevent water penetration performance well.
Moreover, the production technology of country's paper diaper counterdie is also in a lower level, domestic high-end diaper at present
The counterdie used also relies primarily on external import.
A kind of preparation method of waterproof and breathable paper diaper counterdie is disclosed in patent CN201510505147.0, provides one
Kind waterproof and breathable paper diaper counterdie, compound waterproof ventilative layer, the substrate layer are that gas permeability is 100 including substrate layer and therewith
~700CFM, the non-woven fabrics fiber layer with a thickness of 5~20GSM, the waterproof ventilative layer are nanofiber accumulation body layer.Also provide
A kind of preparation method of waterproof and breathable paper diaper counterdie is set using hydrophobic polymer resin by mass production high-voltage electrostatic spinning
It is standby, electrostatic spinning is directly carried out on superfine fibre nonwoven cloth forms nanofiber accumulation body, the nanofiber of production and ultra-fine
The compound paper diaper counterdie of fabric nonwoven cloth, water pressure resistance can achieve 4000mmH2O or more, at the same gas permeability reach 3CFM with
On, steam penetrating capacity reaches 10000g/cm2.24h more than, the blank of domestic high water-proof breathable properties counterdie production has been filled up, it is thorough
Bottom solves the problems, such as leakage of urine and hip redness when baby wears paper diaper.
It is dry that a kind of high antibacterial of body surface, superabsorbent water, ventilative healthy functions are disclosed in patent CN201510322278.5
Refreshing paper diaper, the paper diaper include crotch liquid absorption area, the crotch liquid absorption area include skin-proximal surface layer, from
Water absorption layer that surface layer is set gradually downwards, outermost ventilative leakproof film, it is characterised in that: the surface layer includes being spun by vacation bonding
Web is glued through carrying out online or with carding fiber net having middle layer for entangled bonded layer, surface made of spun lacing reinforcing offline
The Hydroentangled integrated non-weaving cloth base fabric that layer is carded fiber layer, bottom surface layer is false bonded spunbond fibrous layer, the combing are fine
Net is tieed up by with the hydrophilic staple card networking comprising chitin fiber and mint fibers, the vacation bonded spunbond fiber
Net is reinforced by hot rolling after the thermoplastic fibre continuous yarn spinning networking after the processing of drop modulus and hydrophilic treated, forms the vacation
Hot rolling bonding point is less than thermoplastic fibre long filament itself to cohesive force caused by fiber between the fiber of bonded spunbond web
Strongly, the carded fiber layer and skin attachement, false bonded spunbond fibrous layer are combined with water absorption layer.
Disclosing one kind in the utility model patent paper nappy of structure " improve " of Publication No. CN2335608 can produce pair
Flow the paper nappy that air improves the improvement structure of gas permeability and wrinkle-free phenomenon generation tool spring-go.The paper nappy of the utility model its
Structure is mainly placed separately between PE outer layer and absorbent core layer one layer of air-permeable mattress, this is saturating using PE material tool spring-go
Air cushion surface is that have several cross frame ribs in arcuation protuberance, the absorbent tampons layer for keeping top surface laminating by the cross frame rib and not
The close pressing and forming of woven fabric permeable formation in the hemispherical surface of relief so that based on paper pulp material manufactured absorbent tampons layer in
Still spongiosa or deformation do not form agglomerate and still have fine air permeability after absorption secretion.
