Abstract
To solve a problem that a deodorant function deteriorates before usage of an absorbent article provided with the deodorant function using a deodorant. SOLUTION: This absorbent article (party liner) 1 comprises a liquid permeable top sheet 2, a back sheet 3, and an absorbent core 4 sandwiched between both the sheets. A liquid or semi-solid solvent 8 nonvolatile at 20 DEG C is provided between the top sheet 2 and the absorbent core 4. Cyclodextrin is dissolved in the solvent 8. The solvent 8 is propylene glycol, glycol, 1,3-butylenediol, triethyl citrate, diethyl phthalate, or the like. The deodorant function of cyclodextrin does not deteriorate before usage, and the deodorant function of cyclodextrin appears rapidly during usage.
Description
Technical field
The present invention relates to the absorbent commodity of sanitary towel, protective pad, incontinence pad, disposable diaper etc., the absorbent commodity that particularly has the deodorize function.
Background technology
The excremental whiles such as the urine that absorbent commodity main purposes such as sanitary towel, protective pad, incontinence pad, disposable diaper are to discharge in absorbing by body, stool, antiperspirant, leucorrhea, blood, menses do not backflow but above-mentioned Excreta are remained in the absorbent commodity.But excremental abnormal smells from the patient is very undesirable for the people that user or processing are absorbed with excremental absorbent commodity.In addition, be absorbed with excremental absorbent commodity when continue using, the bacterium of existence breeds as nutrient source with Excreta between hip etc., further produces undesirable abnormal smells from the patient.
As the prior art that is used to remove this undesirable abnormal smells from the patient, for example special surface or the reverse side put down in writing in the flat 5-68694 communique at absorber opened is provided with the absorbent commodity that applies or be impregnated with the absorption paper of antibiotic property silica gel and acrylic resin.This is to prevent that by above-mentioned antibiotic property silica gel and acrylic resin as antibacterial bacterial multiplication from causing producing undesirable abnormal smells from the patient, eliminates the excretal odor by the deodorize function with above-mentioned antibacterial.In addition, the spy shows to disclose in the flat 10-508218 communique and mix the absorbent commodity of POLARGEL NF as deodorant in absorbent cores.
But above-mentioned spy opens the absorbent commodity of flat 5-68694 communique and the flat 10-508218 communique record of Te Biao when having absorbed Excreta, and deodorants such as silica gel or POLARGEL NF are directly flooded by Excreta.The occasion of porous deodorant, the deodorant surface is covered by above-mentioned Excreta, can not give full play to the deodorize function, promptly has the low problem of deodorising effect.
In addition, put down in writing in the flat 8-508424 communique of special table that to contain granularity be that not compoundization cyclodextrin below 12 microns is as the protective pad of deodorant.Because the odorous substance that exists around the granularity circlet dextrin enclose shows deodorization functions.But, under the state before use and since airborne moisture cyclodextrin inclusion compound airborne chemical compound.Therefore, during use can enclose the foul smell quantitative change few, deodorization functions descends.And cyclodextrin is a micropowder of having stipulated granularity, comes off from absorbent commodity easily.In addition, use polymer as binding agent the powder of cyclodextrin to be fixed on situation on the absorbent commodity though also disclose, the absorbent commodity hardening damaged its feel.
Summary of the invention
The invention solves the problem before above-mentioned, its purpose is to provide a kind of absorbent commodity, and it can prevent that the function of the deodorant that is provided with on the absorbent commodity from reducing before use, can give full play to deodorizing effect in use.
Further aim of the present invention is to provide a kind of absorbent commodity, even cyclodextrin is fixed on the absorbent commodity as deodorant, also can not damage the feel of the material that constitutes absorbent commodity.
Absorbent commodity of the present invention is characterised in that comprising liquid permeability top layer and backing layer and be clipped in to contain in the absorbent commodity of above-mentioned absorbent cores between two-layer and cyclodextrin is dissolved in 20 ℃ of materials that obtain in nonvolatile liquid or the semi-solid solvent down.
In the absorbent commodity of the present invention, the cyclodextrin with deodorization functions is fixed on the absorbent commodity with dissolved state by nonvolatile solvent.Because cyclodextrin is present in the nonvolatile solvent before using, do not contact with the moisture of trace in the air, can the airborne odorous substance of enclose.In addition, if excremental moisture contacts with cyclodextrin during use, then can the enclose odorous substance.Therefore, the deodorize function that has of cyclodextrin does not reduce before use.In addition, cyclodextrin is fixed on the absorbent commodity by nonvolatile liquid under the room temperature or semi-solid solvent, can be owing to the pliability and the feel of solvent damaged material.
Above-mentioned cyclodextrin is enclose not preferably.
In addition, the preferred boiling point of above-mentioned solvent is at glycol more than 40 ℃ or esters organic solvent.
At this moment, preferred above-mentioned glycol is at least a chemical compound that is selected from propylene glycol, dipropylene glycol and the 1,3 butylene glycol, and above-mentioned esters organic solvent is at least a chemical compound that is selected from triethyl citrate and the diethyl phthalate.
Above-mentioned cyclodextrin be part methylization and/or acetylizad α-, β-and/or gamma-cyclodextrin.
Above-mentioned solvent also can further contain at least a odor inhibitor that is selected from zeolite, silica gel, active carbon, kieselguhr, the water solublity antimicrobial compound.

Fig. 1 is the oblique view of in the embodiment of absorbent commodity of the present invention protective pad partly being cut open.Fig. 2 is the II-II line profile of Fig. 1.
The specific embodiment
Following with reference to description of drawings the present invention.Protective pad 1 shown in Figure 1 have with skin directly contact constitute the liquid permeability top layer 2 be subjected to the liquid side, downside can barrier liquid backing layer 3, be arranged at the 3-tier architecture of the absorbent cores (liquid absorption layer) 4 between above-mentioned top layer 2 and the backing layer 3.Top layer 2 and backing layer 3 melt type binding agent etc. by heat around absorbent cores 4 bonded to each other.And the solvent 8 that contains cyclodextrin is coated in absorbent cores 4 on the surface of top layer 2, is globule decorative pattern shape.
Cyclodextrin has the ring-type outside on substantially and is hydrophilic, and the inboard is hydrophobic character.And, because the existence of moisture is with the inboard of molecule inclusion at ring.Cyclodextrin used in the present invention is for easy enclose odorous substance, preferably the cyclodextrin of enclose (compoundization not: in the ring not any material of enclose) not.But, the cyclodextrin of spice etc. that also can contain a small amount of enclose.In addition, the preferred main component of cyclodextrin be α-, β-, gamma-cyclodextrin and/or its mixture.α after the more preferably chemical modification (methylate, acetylation)-, β-and/or gamma-cyclodextrin.
Cyclodextrin exists with the state of dispersing and dissolving in solvent 8.Solvent is nonvolatile liquid or a semi-solid material under the room temperature (20 ℃).Because cyclodextrin exists with the state in nonvolatile at normal temperatures liquid of dissolving or the semisolid, the moisture that exists in the air contacts with cyclodextrin hardly usually, and protective pad 1 cyclodextrin does not before use have the airborne chemical compound of enclose.In addition, if protective pad 1 absorbs discharged liquid during use, its moisture contacts with cyclodextrin by solvent.As a result, the excremental odorous substance of cyclodextrin inclusion compound shows deodorization functions.
In addition, because the solvent 8 that cyclodextrin is fixed on the protective pad 1 is liquid or semisolid, even be arranged on the protective pad 1, absorbent commodity can hardening not damage feel yet.In addition, if the dissolving cyclodextrin is with cyclodextrin fixedly on the protective pad in the evaporable at normal temperatures solvent, then solvent can volatilize in the preservation process of protective pad, causes cyclodextrin to become solid and separates out.As a result, the protective pad hardening damages feel.In addition, it also is same becoming solid solvent under the use room temperature.
Solvent 8 preferred skin irritations are low not to have dysgenic material to human body, more preferably can add the material in the cosmetics to.Preference such as boiling point are at glycolss such as the propylene glycol more than 40 ℃, dipropylene glycol, 1,3 butylene glycol, esters organic solvents such as triethyl citrate, diethyl phthalate.
In addition, there is no particular limitation for the amount of the cyclodextrin that contains in the solvent 8,1～80 quality % for example, preferred 20～60 quality %.But because the content of cyclodextrin is many more, the viscosity of solvent 8 is big more, will become to be difficult to coating in manufacturing process.
For the solvent 8 that will contain cyclodextrin is coated on the absorbent cores 4, can adopt the whole bag of tricks.For example use slit coater, roller coater to apply, or use aerosol apparatus etc. to apply.
The solvent 8 that contains cyclodextrin also can be arranged on the whole absorbent cores 4 very close to each otherly, but because when absorbing discharged liquid, discharged liquid is difficult to move to absorbent cores 4, therefore preferred setting does not apply the zone of solvent 8.For example, can be applied as globule decorative pattern shape (round point shape) as depicted in figs. 1 and 2.In addition, solvent 8 also can be applied as striated or helical form.
In addition, the solvent 8 that contains cyclodextrin can be coated on the absorbent cores 4, but also can be coated in absorbent cores 4 one sides of top layer 2.In addition, solvent 8 can be arranged on top layer 2 one sides of whole absorbent cores 4, but also can only be arranged on the directions X of the main absorbed protective pad 1 of discharged liquid and the central part of Y direction.
In addition, except that cyclodextrin, also can contain zeolite, silica gel, active carbon, kieselguhr, water solublity antimicrobial compound, their odor inhibitors such as mixture in the solvent 8.Above-mentioned active carbon also can be to add alkali, add this class of acid and add active carbon.In addition, zeolite x/nMnAlO
2YSiO
2ZH
2O represents.Wherein, x, y are respectively integer, and M is a cation, n be on the cation with charge number.M is the cation of wide scope, for example Na
+, K
+, NH4
+, alkylammonium, heavy metal etc.In addition, bentonite is a natural minerals, is meant calcium bentonite, sodium bentonite.But, preferably under the condition of the deodorization functions that does not reduce cyclodextrin, contain these odor inhibitors.
The top layer 2 that constitutes protective pad 1 is formed by the liquid permeability sheet material that sees through fluid bodily things such as menses, urine, antiperspirant.For example on non-knitting (spanless) non-woven fabrics that natural fiber and/or synthetic fibers form, hot sticky type (thermal bonding) non-woven fabrics, point bonding (point bond) non-woven fabrics, ventilation type (airthrough) non-woven fabrics etc., implement the material of perforate processing.In addition, can be to have implemented resin sheets such as polyethylene that perforate handles or polypropylene.
Backing layer 3 is liquid impermeability and aeration, is for example formed by resin sheet of polyolefin resin etc.Perhaps, also can use non-woven fabrics, between backing layer and absorbent cores, waterproof membrane is set as backing layer.In addition, be layered on other absorbent commodity when using and also can form by liquid permeability sheet material.
Absorbent cores 4 by absorbent material for example the mixture etc. of comminution pulp or comminution pulp and high water absorbency polymer form, the mixture of comminution pulp or comminution pulp and high water absorbency polymer is coated by absorbent sheets such as cotton papers.
In the above-described embodiment, be that the occasion of protective pad is narrated for absorbent commodity, the present invention also is applicable to sanitary towel, opening diaper, be pre-formed the diaper of pants type, get urine liner and medical or health with absorbing liner etc.In addition, also be applicable to the hydrolytic absorbent articles that can wash away in the lavatory after the use.
Wherein, diaper or get the occasion that urine liner etc. absorbs the absorbent commodity of large quantity of moisture also can contain the solvent of cyclodextrin in absorbent cores 4.At this moment, solvent 8 can not appear on the surface of top layer 2, solvent 8 can skin attached to user yet on.In addition, solvent 8 also can be arranged on backing layer 3 one sides of absorbent cores 4 surface, backing layer 3 absorbent cores 4 one sides the surface or do not exist absorbent cores 4 absorbent commodity around the position.
