Specific embodiment
Below by way of specific embodiment, the invention will be further described.
A kind of disposable adsorption object provided by the invention is in long strip, in use it is generally necessary to be placed on wearing
Around the crotch of person.Disposable adsorption object has the Y and transverse direction X in a longitudinal direction, and term " longitudinal direction " as used herein refers to
The imaginary direction of one of absorbing articles, the direction are consistent with disposable adsorption object length direction；Be laterally with longitudinal direction just
It hands over, the direction is consistent with the width direction of disposable adsorption object or waistline direction.Disposable adsorption object has in its longitudinal direction
Front waist region is arranged towards the abdomen part of user by front waist region, crotch region, rear waist region when in use
Domain, and downwardly against inguinal region, while crotch region is configured to substantially under the crotch of user
Side, rear waist region is arranged towards the buttocks of user.
A kind of disposable adsorption object 1 has the surface material 2 of liquid permeability, the primer 4 of opaque liquid and is located at
Absorption between liquid permeability surface material 2 and the primer 4 of opaque liquid and the absorbent core layer 3 for accommodating liquid.Disposable
The both lateral sides of absorbing articles are provided with the leakproof edge 6 extended longitudinally, have respectively in front waist region and rear waist region
A pair of of the flank 5 being laterally extended is provided on the flank 5 of any waist area in front waist region and rear waist region
Left and right waist patch, left and right waist patch can with matching piece that another waist area is arranged in is separable is bonded into the disposable of pant like
Absorbing articles.The past primer far from wearer of the liquid permeability surface material of disposable adsorption object from contact wearer skin
Direction on be respectively provided with the surface layer of liquid permeability, absorb and the bottom of the absorbent core layers of receiving body fluids, opaque liquid, but it is unlimited
In above three layers.Above-mentioned is only to illustrate, and disposable adsorption object may also include the distribution of the liquid under liquid permeability surface material
Layer, transport layer, retaining layer etc..Absorbent core layer is arranged between liquid permeability surface layer and liquid impermeable.Liquid permeability surface layer and liquid-tight
Outer region of the bottom on the outside of absorbent core layer is by passing through heatmeltable adhesive bonding, heat bonding or ultrasonic bonding etc. disposable
The juncture of absorbent item field routine engages.
Liquid permeability surface layer 2 is preferably submissive, soft feel and the material having no stimulation to wearer skin.In addition, face
Layer is transparent liquid, and liquid can penetrate rapidly its thickness.Suitable liquid permeability surface layer 2 can be made of a variety of materials, such as by spunbond
Non-woven cloth, hydro-entangled non-woven fabric, Through-Air Thermal Bonded Nonwovens, Nonwovens, the degradable nonwoven fabrics such as PLA, PBS are made.
In addition, liquid permeability surface layer 2 is also possible to a kind of porous formed film.The porous formed film is preferably a kind of three-dimensional porous formed film,
The permeable body fluid of the film, no absorbability can be reduced liquid reflux and avoid rewetting wearer skin.Therefore, body is contacted
Porous formed film surface keeps dry and comfortable, to reduce the contamination to body, brings more comfortable feel to wearer.It is porous formed
Film face layer contacts body or exposure surface can have hydrophily and being handled with surfactant, this helps to make liquid
Body penetrates surface layer, and transmission speed is faster than the contact body surface transmission speed of non-hydrophilic, to reduce body fluid effluent face
Layer is without flowing into absorbent core layer and being absorbed a possibility that sandwich layer absorbs.
Liquid impermeable 4 is made of flexible material, the material impenetrable liquid (such as menstruation and/or urine), to prevent liquid
Body may be squeezed out from absorbent core layer 3, otherwise may unexpectedly make absorbent core layer absorb and the body fluid kept overflows to connect
The underwear of touching and pollution wearer.Liquid impermeable 4 can be by being processed into the textile fabric or non-woven fibre of impenetrable liquid
Material, perhaps polyacrylic thermoplastic film is made or composite material such as ventilated membrane and nothing thin polymer film such as polyethylene
Woven fabric is combined.In addition, the liquid impermeable 4 can permit moisture from absorbent core layer evolution (i.e. ventilative), while also preventing
Body fluid passes through liquid impermeable 4.
Absorbent core layer 3 is for absorption and receiving body fluids.Absorbent core layer 3 usually can be by any soft, submissive, comfortable, right
Wearer skin has no stimulation and can absorb and retain the material of internal body fluid and is made.Absorbent core layer can be by primary
The property general plurality of liquid absorbing material of absorbing articles is made.The example of suitable absorbing material includes that the wood pulp crushed (leads to
Frequently referred to staple fiber), corrugated cellulose wadding, modified cross-linked cellulose fibres, capillary channel fiber (the i.e. prior art
In fiber in the fiber with capillary channel), hygroscopic foam is thermally bonded airlaid material, and moisture absorption sponge synthesizes short fibre
Dimension, polymer fiber, high absorption polymer, the combination of peat moss suede or the other equivalent materials of heat seal or above-mentioned material, but not
It is limited to above-mentioned material.Absorbent core layer can be the knot that above-mentioned hygroscopic material is clipped by upper layer and lower layer paper fiber (or bonded fabric)
Structure, or can be the structure that above-mentioned hygroscopic material is wrapped up by paper fiber.
The material of leakproof edge is liquid-tight material, can be water resistant (hydrophobic) non-woven cloth, thin-film material
Or other common water-resistant materials of disposable adsorption object.These materials be it is hydrophobic, body fluid is impermeable, more preferably
It is ventilative and impenetrable liquid.
The leakproof edge 6 extended longitudinally is provided in the both lateral sides of disposable adsorption object, leakproof edge 6 includes connecing
Conjunction portion 61, base portion 62 and be connected to base portion 62 and be located at 62 upper end of base portion freedom portion 63, the leakproof edge 6 is in its base portion 61
It engages on the surface layer and/or primer, a plurality of bullet to stretch along absorbing articles longitudinal direction is provided in freedom portion 63
Property element, elastic element 60 be generally 3-10 item.The disposable adsorption object is described in just relaxed state or in use state
Freedom portion 63 is rendered as the three-dimensional shape of circular ellipse, and the elasticity member under the elastic shrinkage of elastic element 60
