Description of drawings
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.
