Abstract
The utility model discloses a kind of double-deck perforation absorbing materials of sanitary napkin,The sanitary napkin includes the precoat by stacking gradually from top to bottom,Guide layer,Absorbed layer,Protect counterdie,Gum release paper and coating,It is provided with structural adhesive layer between above-mentioned neighboring layers,Absorbed layer initiative uses the double-deck perforation absorbing material,Using double-layer structure,That is upper layer wood pulp and hot-melt short fiber mixing,Lower layer is by SAF,Wood pulp cellulose and hot-melt short fiber mode,Pass through heat pressing process one-pass molding,Bilayer perforation absorbing material is provided with the air hole of evenly distributed perforation,Since SAF is fibre morphology,In the production and use process,It is not easy to shift,It is precipitated and discrete,This environmentally friendly and health brings positive influences,And when to material perforation processing,SAP particulate matters are not had to fall,Both environmental protection had been reached and had reduced and wasted,The gas permeability of product can be greatly promoted again.
Description
Technical field
The utility model is related to a kind of amenities, more particularly to a kind of double-deck perforation absorbing material for sanitary napkin.
Background technology
With economic development and improvement of living standards, people are more next to the consumption demand of disposable sanitary articles more.
Reaching its maturity and opening with consumption idea simultaneously, consumer are desirable for the product of more comfortable ventilating and safety.
Common sanitary napkin uses the mode of wood pulp or dust-free paper mixing super absorbent resin SAP as absorbing material, due to
SAP is particle shape, and during sanitary napkin use, particulate matter is easy to be transferred to product surface by face layer, and SAP's is main
Ingredient is Sodium Polyacrylate salts substances, is formed by chemical process, has certain proportion monomer residue, at gel after water suction
Shape can bring potential security risk if being transferred to human body surface or internal to consumer.
In addition in process of production, SAP is easy to fall, is discrete the absorbing material containing SAP, can cause environmental pollution,
Operating personnel are also easy foreign-body aspiration, cause damages to health, while also resulting in larger waste.
Invention content
The considerations of in view of factors above, this patent utility model SAF substitute the mode of SAP, by with wood pulp and short fibre
Novel sanitary napkin absorbing material is made by mixing into dimension.Since SAF is fibre morphology, in the production and use process, do not allow
Easily transfer, be precipitated and discrete, this environmentally friendly and health brings positive influences.
As above, since SAF is fibre morphology, when to material perforation processing, SAP particulate matters are not had and are fallen, were both reached
Environmental protection and reduction waste, and can greatly promote the gas permeability of product.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of double-deck perforation absorbing material of sanitary napkin, the sanitary napkin include by stack gradually from top to bottom precoat,
Guide layer, absorbed layer protect counterdie, gum release paper and coating, and structural adhesive layer, the suction are provided between above-mentioned neighboring layers
Layer is received using the double-deck perforation absorbing material, using double-layer structure, i.e. upper layer is wood pulp layer, mixed with wood pulp and hot-melt short fiber
It closes, lower layer is that SAF mixing wood pulp layers pass through heat pressing process one-pass molding by SAF, wood pulp cellulose and hot-melt short fiber mode.
The double-deck perforation absorbing material is provided with the air hole of evenly distributed perforation.
The thickness of the double-deck perforation absorbing material is 0.5-3 millimeters, and grammes per square metre is that weight is 80-300 grams/m.
The arrangement density of the air hole is 5-30/square centimeter.
The water absorbent rate of the double-deck perforation absorbing material is 20-45 times.
The air penetrability of the double-deck perforation absorbing material is more than 800mm/s.
The utility model has the beneficial effects that：A kind of double-deck perforation absorbing material of sanitary napkin of the utility model, is started
Property in such a way that SAF substitutes SAP, material is absorbed by the novel sanitary napkin that is made by mixing into wood pulp and staple fiber
Material, since SAF is fibre morphology, in the production and use process, it is not easy to shift, be precipitated and discrete, this it is environmentally friendly and
Health brings positive influences, and when to material perforation processing, does not have SAP particulate matters and falls, both reaches environment
Protection and reduction waste, and the gas permeability of product can be greatly promoted.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；

Specific implementation mode
Referring to figs. 1 to Fig. 3, the sanitary napkin include by stack gradually from top to bottom precoat 1, guide layer 2, absorbed layer 3,
Counterdie 4, gum release paper 5 and coating 6 are protected, structural adhesive layer is provided between above-mentioned neighboring layers, the absorbed layer 3 uses double
Layer perforation absorbing material, is formed by hot pressing mode by double-layer structure, and upper layer is wood pulp layer 21, and lower layer is SAF mixing wood pulps
Layer 22, the utility model initiative use the double-deck perforation absorbing material, and using double-layer structure, i.e. upper layer is wood pulp layer, by wood
Slurry and hot-melt short fiber mixing, lower layer is SAF mixing wood pulp layers, by SAF, wood pulp cellulose and hot-melt short fiber mode（This
Place is mixed into simple be simply mixed）, by heat pressing process one-pass molding, bilayer perforation absorbing material is provided with evenly distributed
The air hole 7 of perforation, wherein SAF are the abbreviation of super absorbent fiber, i.e. superabsorbent fiber, have preferable inhale
Aqueous energy.The utility model it is initiative in such a way that SAF substitutes SAP, by being made by mixing with wood pulp and staple fiber
At novel sanitary napkin absorbing material,
The weight percent that the SAF accounts for the lower layer SAF mixing wood pulp layers of the double-deck perforation absorbing material is 60-80%,
The weight percent of the lower layer SAF mixing wood pulp layers of the double-deck perforation absorbing material is 12-37%, institute shared by the wood pulp cellulose
The weight percent for stating the lower layer SAF mixing wood pulp layers of the double-deck perforation absorbing material shared by hot-melt short fiber is 3-8%.
The weight percent that the wood pulp accounts for the upper layer wood pulp layer of the double-deck perforation absorbing material is 92-97%, the heat
