Description

A kind of sanitary napkin of PLA surface layers
Technical field
The present invention relates to a kind of amenities, more particularly to a kind of sanitary napkin.
Background technology
With economic development and improvement of living standards, consumption demand of the people to disposable sanitary articles is more next more. Reaching its maturity and opening with consumption idea at the same time, consumer is desirable for more comfortable and safe product.
Common disposable sanitary articles, such as：Sanitary napkin, protection pad, urine pants generally do surface layer using hot wind and spun-bonded non-woven fabrics, These non-woven fabrics are fabricated using chemical fibre as raw material, and natural texture is poor during use.In addition, when fiber produces such as Control the trace level chemical substances such as improper meeting residual catalyst, reaction monomers；Chemical fibre is generally with certain content chemistry oil Agent etc., these can bring potential security risk to consumer；In addition, the equal non-degradable of these materials brings environmental protection Negative effect.
In view of the consideration of factors above, a kind of sanitary napkin of invention, initiative mixes with degradable poly lactic acid Condensating fiber spunlace non-woven cloth substitutes traditional surface layer, with reference to the optimization design of the product structures such as perforate guide layer, obtains consumer Safer healthy experience, while environmentally friendly bring positive influences.
The content of the invention
For overcome the deficiencies in the prior art, present invention offer is a kind of to make consumer obtain safer healthy experience, together When the environmentally friendly sanitary napkin for bringing positive influences.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of sanitary napkin of PLA surface layers, including precoat, guide layer, absorptive core, the anti-river bottom protection stacked gradually from top to bottom Film, release liners and coating, are provided with structure glue between above-mentioned neighboring layers, the precoat is degradable poly lactic acid composite fibre Spunlace non-woven cloth, the guide layer are punching hot-wind nonwoven cloth or fabric hot rolled nonwoven fabrics, and air hole is provided with the guide layer.
The precoat is made of 20-50% acid fiber by polylactic mixing 50-80% viscose rayons.
The precoat is made of 20-50% acid fiber by polylactic mixing 50-80% Lyocell fibers.
The grammes per square metre of the precoat is 30-50 grams/m.
The longitudinal diffusion length of the guide layer is more than 50mm, and horizontal proliferation width is more than 30mm.
The grammes per square metre of the guide layer is 25-35 grams/m.
The diameter of the air hole is not less than 0.2mm.
The density of the air hole is no less than 5 every square centimeter.
The water absorbent rate of this sanitary napkin is at 15-40 times.
The beneficial effects of the invention are as follows：Of the invention initiative replaces with degradable poly lactic acid composite fibre spunlace non-woven cloth Generation traditional precoat, with reference to the optimization design of the product structures such as the guide layer for possessing air hole, obtains consumer safer strong The experience of health, while environmentally friendly bring positive influences.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure sectional view of the present invention.
Embodiment
With reference to Fig. 1, a kind of sanitary napkin of PLA surface layers, including stack gradually from top to bottom precoat 1, guide layer 2, inhale Core 3, protection counterdie 4, release liners 5 and coating 6 are received, is provided with structure glue between above-mentioned neighboring layers, the precoat 1 is can Degraded polylactic acid composite fibre spunlace non-woven cloth, the guide layer 2 are to punch hot-wind nonwoven cloth or fabric hot rolled nonwoven fabrics, the water conservancy diversion Air hole is provided with layer 2, wherein PLA is polylactic acid, and initiative uses degradable poly lactic acid composite fibre spunlace non-woven cloth Traditional precoat is substituted, with reference to the optimization design of the product structures such as the guide layer for possessing air hole, obtains consumer safer The experience of health, while environmentally friendly bring positive influences.
In the present embodiment, the precoat 1 is made of 20-50% acid fiber by polylactic mixing 50-80% viscose rayons（This Place is mixed into simple be simply mixed）, or the precoat 1 is using 20-50% acid fiber by polylactic mixing 50-80% lyocells fibre Dimension is made（Simple be simply mixed is mixed into herein）, the grammes per square metre of the precoat 1 is 30-50 grams/m, light air ventilation, Wherein Lyocell fibers be the pulp formed after being smashed to pieces using natural plant fibre as raw material, be made by organic solvent spin processes, Have a variety of excellent performances of natural fiber and synthetic fibers, gloss is naturally, slippery feel, and intensity is high, substantially shrink-proof, Er Qietou Moist, good permeability, soft, comfortably, smooth nice and cool, drapability is good, is a kind of outstanding cellulose fibre.
The absorptive core 3 is wrapped up by one layer of water lock layer 13, and the absorptive core 3 is additionally provided with perforative absorbing rod 14, When absorptive core 3 is drawn onto the limit, since the effect moisture of water lock layer 13 will not ooze out, absorbing rod 14 is capable of accelerating liquid Absorb.
In addition the longitudinal diffusion length of the guide layer 2 is more than 50mm, and horizontal proliferation width is more than 30mm, the guide layer 2 grammes per square metre be 25-35 grams/m, the air hole for circular, oval, rectangle, abnormity etc. all kinds of geometries, The diameter of the air hole is not less than 0.2mm, and the density of the air hole is no less than 5 every square centimeter so that product imbibition Quick diffusion afterwards, helps surface layer to obtain good dry-ness, the water absorbent rate of this sample sanitary napkin is at 15-40 times.
