Technical field
The invention belongs to personal hygiene care article fields, are related to a kind of antibacterial health of breathing certainly with air hinge
Towel, and in particular to one kind is used for women physiological period privates care product.
Background technology
Many women can seal very tight in physiology phase the body privates of oneself, and main purpose is exactly that peculiar smell is isolated,
Female friend is ignorant to be：This have the consequence that opposite, close tighter, peculiar smell will be bigger, and long-term closing can also
Make bacterial growth.
Some women like the sanitary napkin with the additive of class containing essence, also truly have such product in the market, but have the medicine normal
The women of knowledge prefers with sanitary napkin made of natural material, that is, the sanitary napkin without essence class additive, because：In essence
Contain most common germ ingredient.
Medical experiment proves：The peculiar smell that women just has in physiology phase is a variety ofization in menses after menses contact air
After learning substance generation oxidation reaction, so as to just produce peculiar smell, actually, there is no peculiar smell when menses just flow out, and generate different
After taste, if sanitary napkin ventilation is good, peculiar smell can be desalinated.So selection good permeability sanitary napkin be can reduce it is different
Taste, therefore, women is to select the sanitary napkin of good permeability in the best scheme of physiology phase isolation peculiar smell.
If women privates is sealed very tight, moisture cannot distribute, and also easily grow germ, can more cause reproductive system each
Kind health problem.Many female friends both know about：Intermenstrual period, the resistance of reproductive organs are to decline, if in menstrual period, female
Property privates nursing it is improper, be particularly easy to that inflammation of genito-urinary system disease or infection occurs.
Present-day medical knowledge is taught that：Women physiology phase keep privates drying be women keep fit in menstrual period and
Prevent the best protection method of gynaecological disease.This is because：Women has ' itch ' phenomenon in physiology phase privates, in excessive menstruation
When, itch can be more serious, and this itch is precisely due to sanitary napkin lacks what permeability generated.
' itch ' phenomenon is medically known as：Pruritus vulvue, pruritus vulvue are a kind of symptoms very common in gynecological disease,
Vulva is especially sensitive position, and a variety of lesions of gynaecology and external irritant can cause itch, makes one sleeping and eating difficulty peace, sitting and lying not
Rather.According to medicine common sense：Vulva is unclean and close-fitting chemical fibre underpants, sanitary napkin etc. cause it is penetrating it is bad be pruritus vulvue a weight
Want reason.
The privates skin of women is more delicate, is chronically at an air-locked environment, easily causes above-mentioned health problem.
Particularly city white collar bends over one's desk working for a long time, in hot summer, using the low sanitary napkin of gas permeability, external genital will be made often to locate
In damp and hot environment, and the local bacterium of hot humid is easy to grow.So airtight sanitary napkin easily grows bacterium,
And the nutriment in menses is exactly " culture solution " of bacterium, bacterium one, which grows, to be easy for causing gynaecological disease.Therefore, selection is ventilative
The good sanitary napkin of property is that can to prevent gynaecology pathogenetic.
In addition, numerous female consumers has sultry feeling when using sanitary napkin, women is when using sanitary napkin
It is to need frequently to change sanitary napkin, the time of general replacement sanitary napkin is primary for the hours replacement of four or five, interval, when flow is more, is spaced
2~3 hours are replaced once, why replace sanitary napkin in the extremely short time and also have sultry feeling, are because in the market
Existing sanitary napkin airing function is simultaneously not perfect.
The bad sanitary napkin of gas permeability, women using when it is airtight just have sultry feeling, be because：Human body it is normal
37 ° of temperature, after the sanitary napkin for using gas permeability bad, the privates temperature of human body will rise, and human body can also perspire sometimes, more
Sultry feeling, if sanitary napkin permeability is good, can take the heat in sanitary napkin out of when exacerbating women using sanitary napkin
Amount, so as to reduce privates body temperature.Therefore, the sanitary napkin of good permeability is selected, it can be to avoid sultry feeling.
Most of sanitary napkin is using the poor PE films of permeability in the market, can cause in this way body easily it is damp and hot simultaneously
With peculiar smell, local skin itch, air circulation not, sensitive skin is caused serious injury.
And the sanitary napkin with airing function more in the market, it is by discharging the gas in sanitary napkin by gas permeation bottom film
, however, it is understood that：The existing sanitary napkin with airing function relies solely on gas permeation bottom film made of PE plastics to discharge

In order to illustrate the present invention, the range being not intended to be limiting of the invention.
The present invention it is a kind of with air hinge from respiration health towel the 1st layer be air duct layer 1-1, by hydrophilic nonwoven fabrics
The 1-2 and its water repellent nonwovens 1-3 in left side, on the right side of water repellent nonwovens 1-4, also its lower floor coarse denier fiber non-woven fabrics
1-5 is built jointly, and the channel 1-6 that will form air circulation in the middle part of the air duct layer after building, outside air 1-50 pass through parent
Water non-woven fabrics 1-2, water repellent nonwovens 1-3,1-4 enter air duct layer 1-1, take away the heat in air duct layer 1-1, and turn
Become low-grade fever air 1-60.
Air duct layer operation principle be：It is not easy to retain using hydrophilic nonwoven fabrics, water repellent nonwovens, coarse denier fiber non-woven fabrics
The characteristic of liquid, so liquid can be quickly through hydrophilic nonwoven fabrics, water repellent nonwovens, coarse denier fiber non-woven fabrics, it and can't
It is absorbed by hydrophilic nonwoven fabrics, water repellent nonwovens, coarse denier fiber non-woven fabrics, the dry and comfortable of air duct layer is kept with this；It is utilized
Coarse denier fiber nonwoven fabric construct is fluffy and the characteristic of water repellent, is supported by the use of coarse denier fiber non-woven fabrics as the bottom of air duct, comes
Ensure the unimpeded of air duct；Using being superimposed compact technique, that is, in hydrophilic nonwoven fabrics 1-2 both sides, by its left side water repellent nonwovens
The 1-3 and its water repellent nonwovens 1-4 on right side is connected as an entirety, in the spunlace non-woven cloth of lower floor by mechanical ramming mode
After 1-5 is added in, this 4 layer material builds an air duct 1-6 jointly.This air duct can increase while ventilating air
Consumer uses comfort level during this product.
In order to further illustrate the operation principle of air duct layer, we enter schematic diagram by reference air channel layer air,
See Fig. 2.The principle for design that the present invention will be described in detail.
Sanitary napkin air duct layer 2-1 of the present invention, hydrophilic nonwoven fabrics 2-2 are with left side water repellent nonwovens 2-3 only at two
The edge of material forms superposition line 2-6 by mechanical ramming；Equally, hydrophilic nonwoven fabrics 2-2 and right side water repellent nonwovens 2-4 be only
It is superimposed at the edge of two materials by mechanical ramming, and forms superposition line 2-7.The effect of this two superposition lines is only two
Connecting line is the connecting line of two materials.This connecting line does not stop that outside air 2-5 enters sanitary napkin air duct of the present invention
Layer 2-1, that is, outside air 2-5 can enter air duct layer 2-1 by any direction.
In order to limit flowing of the liquid in sanitary napkin, it is compacted by mechanical device on sanitary napkin, is pressed on sanitary napkin
There is antiseepage recessed channel 2-8, for further flowing of the limitation liquid in sanitary napkin, while antiseepage recessed channel is pressed, prevent in sanitary napkin
It oozes both sides inside recessed channel 2-8 and is pressed with limit liquidus 9 and limit liquidus 10.Antiseepage recessed channel is with limit liquidus in limitation liquid jointly in sanitary napkin
Simultaneously, for air duct layer remaining air enters the minimum entrance area of sanitary napkin for interior flowing, that is, liquid is only in limit liquid
It is retained in line 9, without crossing limit liquidus 9, air duct layer is made to have enough air to enter area.
From the above mentioned：It can realize that the present invention claims hydrophilic nonwoven fabrics 1-2 for air duct layer 1-1 both sides superimposing technique
For high grammes per square metre non-woven fabrics, the grammes per square metre scope 20g-40g/m2, the water repellent nonwovens 1-3 and 1-4 of hydrophilic nonwoven fabrics 1-2 both sides are
Low grammes per square metre non-woven fabrics, the grammes per square metre scope 14g-24g/m2, gram of the coarse denier fiber non-woven fabrics 1-5 of hydrophilic nonwoven fabrics 1-2 lower floors
Weight ranging from 40g-60g/m2。
The reason of being configured so that be：Middle section can make sanitary napkin using the big hydrophilic nonwoven fabrics 1-2 of the high thickness of grammes per square metre
Surface is not wrinkled, increases the comfort of user.This is because：High grammes per square metre hydrophilic nonwoven fabrics have the flat physical property of plate.
But sanitary napkin skin-material should be avoided all using high grammes per square metre hydrophilic nonwoven fabrics, this is in order to by using soft water repellent nonwoven
Cloth reduces consumer's discomfort.Intermediate high grammes per square metre hydrophilic nonwoven fabrics 1-2 is by the low high grammes per square metre water repellent nonwovens of both sides simultaneously
1-3/1-4 is raised, and increases the gas free air space of air duct 1-5.
The another advantage being configured so that is：After high grammes per square metre hydrophilic nonwoven fabrics 1-2 is elevated, it is not easy and its lower floor, i.e. sky
The coarse denier fiber non-woven fabrics 1-5 fittings of gas channel layer, so as to keep air duct 1-5 unimpeded.
Therefore, the present invention it is a kind of with air hinge from respiration health towel, by above-mentioned design, air can be reached and led to
Channel layer builds air and enters the channel of sanitary napkin while sanitary napkin surface dry is kept, and keeps empty in air duct layer
The flowing of gas is unimpeded.
Another embodiment of the present invention is：Replace coarse denier fiber non-woven fabrics that can equally reach this using loft non-woven cloth
Invention requirement.
The present invention it is a kind of with air hinge from respiration health towel the 2nd layer be imbibition hinge layer 1-11, by water suction paper wood
Material composition.
The major function of imbibition hinge layer is：While sanitary napkin liquid suction function is kept, according to siphon principle in imbibition
The numerous funnel hole 1-12 of prefabricated arrangement on hinge layer 1-11, will be in guiding sanitary napkin because of the siphon power that funnel hole itself has
Low-grade fever gas 1-60, discharge across imbibition hinge layer 1-11 and downwards, while this is discharged, low-grade fever gas 1-60 bands
The gas with foreign flavor and heat in sanitary napkin are walked, becomes damp-heat air 1-70, therefore, funnel hole is carried for the gas flowing in sanitary napkin
For power, the hinge of air flowing in sanitary napkin is formed, this process is similar to a respiratory, therefore, we term it：Health
Towel breathes certainly.
In order to further illustrate the operation principle of imbibition hinge layer, we refer to imbibition hinge layer structure diagram, see figure
3.The principle for design that the present invention will be described in detail.
The funnel hole 3-2 of numerous queueing disciplines is prefabricated on imbibition hinge layer 3-1, sanitary napkin absorbs blood in use
Liquid, therefore the funnel hole 3-3 of some blood blocking is had, these cannot participate in sanitary napkin by the funnel hole 3-3 that blood blocks
From respiratory, but these funnel hole 3-3 blocked by blood can spread the moisture in blood in imbibition hinge layer 3-1
And heat, this blood moisture diffusion direction 3-4 are the 3-5/3-6/3- that the funnel hole 3-3 surroundings blocked to these by blood are spread
7 etc., as a result, while low-grade fever air 3-8 penetrates imbibition hinge layer 3-1, these moistures and heat will be taken away, and become damp and hot
Air 3-9.
From the above mentioned：The siphon power formed by the funnel hole 1-12 that siphon principle designs attracts low-grade fever air 1-60 saturating
Imbibition hinge layer 1-11 is crossed, takes away moisture and heat in imbibition hinge layer 1-11, the process for becoming damp-heat air 1-70 is can
With realization.The present invention claims imbibition hinge layer 1-11, material is blotting paper, and the grammes per square metre scope of this blotting paper is 120g-
240g/m2, this grammes per square metre scope be it is necessary, less than this grammes per square metre scope funnel hole 1-12 can big portion block, so as to make funnel
Hole 1-12 loses siphon power, can not complete from respiratory function；And more than this grammes per square metre scope, the imbibition hinge layer of sanitary napkin will be made
3-1 is excessively thick and heavy, to bringing discomfort when using.
Another to illustrate that：The plane pattern of these funnel holes 1-12, is shown in Fig. 4, can be ellipse funnel hole 4-
1 or round funnel hole 4-2 or pentagon funnel hole 4-3 or hexangle type funnel hole 4-4；Also may be used

Woven fabric forms, that is, 2 layers of water repellent spun-bonded non-woven fabrics press from both sides 1 layer of water repellent melt spraying non-woven fabrics composition.(English is SMS non-woven fabrics:
Spunbond+Meltblown+Spunbond Nonwovens) belong to compound nonwoven cloth, it is the joint product of spunbond and melt-blown,
Have many advantages, such as strength is high, strainability is good, without adhesive, nontoxic.
Major function is：While keeping preventing liquid from oozing out sanitary napkin function, pressed from both sides using 2 layers of water repellent spun-bonded non-woven fabrics
1 layer of water repellent melt spraying non-woven fabrics form the compound water repellent nonwovens of SMS, i.e. antiseepage exhaust level 1-21.This compound water repellent nonwovens is from upper
Under successively by：Water repellent spun-bonded non-woven fabrics 1-22, water repellent melt spraying non-woven fabrics 1-23, water repellent spun-bonded non-woven fabrics 1-24 totally 3 layers of water repellent
Nonwoven cloth material forms.The SMS water repellent compound nonwoven cloths of this 3 layer material composition have：Porosity is small, and filtration resistance is small, filtering
Efficient characteristic can effectively prevent liquid to ooze out sanitary napkin.Although the exhaust capillary liquid in the compound water repellent nonwovens of SMS
It cannot pass through, but can quickly discharge gas, as a result, through the damp-heat air 1-70 of imbibition hinge layer 1-11, be vented by antiseepage
The irregular gas vent 1-25 discharges gathered on layer 1-21, that is, the damp-heat air 1-80 of discharge is by the compound water repellent nonwovens of SMS

The principle of SMS water repellent compound nonwoven cloths is：The maximum feature of Spunbonded Nonwovens is that fiber is continuous in fibre web
Long filament, compared with other nonwoven products with grammes per square metre, intensity is high, and vertically and horizontally performance approaches, but its networking uniformity and table
Face spreadability is poor.Melt blown non-woven is ultra-fine fiber construction, and fibre diameter is thin, and cloth cover large specific surface area, porosity is small,
Filtration resistance is small, and filter efficiency is high, and surface coverage and shielding properties are fine；And the drawback is that intensity is low, wearability is poor.
The two is combined, the compound water repellent nonwovens formed then compensate for weakness each other just, good with intensity height, wearability
Feature, while there is excellent shielding properties again.
The intrinsic high-strength wearable of the existing spunbond layer of the compound water repellent nonwovens of SMS, while have the intermediate meltblown layer higher again
Filter efficiency, barrier property, anti-particle penetration, hydrostatic pressure resistant, shielding and appearance uniformity, it is achieved thereby that good
Filterability, liquid-proof and opacity.Because of the water-proof breathable properties that the compound water repellent nonwovens of SMS protrude, especially suitable for hygienic city
