Description

A kind of sanitary napkin

Technical field

The utility model relates to a kind of amenities, in particular to a kind of sanitary napkin.

Background technique

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 product that is more comfortable, more ventilative and more trusting.

Sanitary napkin is mostly by more structure compositions such as surface layer, absorbed layer and protection counterdies currently on the market, wherein absorbed layer makes It is formed with dust-free paper or pulpwood mixing polymeric absorbent resin SAP by pressing, the absorbed layer after compacting can obstruct significantly Air and moisture run through up and down, if it is in addition upper improper in surface layer and counterdie selection, such as using non-breathable counterdie and tightly Close surface layer etc., can frequently result in consumer so when in use has bored wet airtight sense, in addition it is bored it is wet under the conditions of be easy to cause Microbial growth etc., these can bring a negative impact to consumer's physical and mental health；In addition to this, due to polymeric absorbent resin SAP is grain shape, is easy to the problems such as falling, be precipitated and shifting in the production and use process, direct labor is in life If during production if protection it is improper be easily inhaled lung, consumer use when product structure design it is bad, SAP particle into Health risk can be brought by entering human body etc..

The considerations of in view of factors above, a kind of sanitary napkin of this patent utility model, completely new with one kind in a creative way The design of combination of materials structure especially both may be used after the combined design of product using completely new SAF mixing wood pulp punching absorbed layer Product permeability is substantially improved, and traditional SAP particle is substituted using SAF due to absorbing layer material, has prevented SAP particle Foreign matter promotes quality of life to be beneficial to consumer's physical and mental health to the risk of personnel health.

Summary of the invention

For overcome the deficiencies in the prior art, the utility model provides a kind of health that good permeability is beneficial to health Towel.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of sanitary napkin, the air penetrability of the sanitary napkin is less than 2000 Grays second, and the sanitary napkin by stacking gradually from top to bottom Precoat, guide layer, SAF perforation absorbed layer, protection counterdie, gum release paper and coating constitute, between above-mentioned neighboring layers It is provided with structural adhesive layer, the SAF perforation absorbed layer is provided with the air hole of evenly distributed perforation, the aperture of the air hole It is 0.25-25 square millimeters, the density of the air hole is 5-30 every square centimeter.

The precoat is using one of hot-wind nonwoven cloth, spun-bonded non-woven fabrics, PE making hole film and spunlace non-woven cloth.

The guide layer is using one of hot-wind nonwoven cloth, spun-bonded non-woven fabrics, PE making hole film and spunlace non-woven cloth.

SAF perforation absorbed layer with a thickness of 0.3-1.3 millimeter, grammes per square metre is 80-300 grams/m.

SAF perforation absorbed layer by 20-40%SAF, 55-75% wood pulp and 5-20% the hot-melt short fiber heat of mixing It presses.

The beneficial effects of the utility model are: the sanitary napkin of the utility model by stack gradually from top to bottom guide layer, SAF perforation absorbed layer, protection counterdie, gum release paper and coating are constituted, and are provided with structure glue between above-mentioned neighboring layers, are started Property the SAF mixing wood pulp punching absorbed layer completely new with a kind of completely new combination of materials structure design, especially application, product After combined design, product permeability can be not only substantially improved, but also traditional SAP is substituted using SAF due to absorbing layer material Particle has prevented SAP particle foreign matter to the risk of personnel health, to be beneficial to consumer's physical and mental health, promotes quality of life.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the structural schematic diagram of SAF perforation absorbed layer.

Specific embodiment

Referring to Fig.1, Fig. 2, a kind of sanitary napkin, the air penetrability of the sanitary napkin is less than 2000 Grays second, and the sanitary napkin is by from upper Precoat 1, guide layer 2, the SAF perforation absorbed layer 3, protection counterdie 4,6 structure of gum release paper 5 and coating stacked gradually under and At the precoat 1 is hot-wind nonwoven cloth, and the guide layer 2 is PE making hole film, is provided with structure glue between above-mentioned neighboring layers Layer, SAF perforation absorbed layer 3 are provided with the air hole 7 of evenly distributed perforation, the SAF perforation absorbed layer with a thickness of 0.3-1.3 millimeters, the grammes per square metre of the SAF perforation absorbed layer is 80-300 grams/m, and wherein SAF is super absorbent Fiber, i.e. superabsorbent fiber have preferable water absorbing properties, and in the present embodiment, the SAF perforation absorbed layer is by 20-40% SAF forms (being mixed into simple be simply mixed herein) with the hot-melt short fiber mixing hot pressing of 55-75% wood pulp and 5-20%, The utility model with a kind of completely new combination of materials structure design, especially applies completely new SAF mixing wood pulp in a creative way Absorbed layer is punched, after the combined design of product, can not only substantially improve product permeability, but also use due to absorbing layer material SAF substitutes traditional SAP particle, has prevented SAP particle foreign matter to the risk of personnel health, so that it is strong to be beneficial to consumer's body and mind Health promotes quality of life,
