Definitions
- the present invention relates to an absorbent article such as a disposable diaper, a urine-absorbing pad, an incontinence pad, a sanitary napkin, and the like, and a method for producing the same.
- the fragrance is encapsulated in an inclusion substance made of cyclodextrin or the like and applied to the absorbent article in order to suppress volatilization of the scent component. This prevents fragrance loss due to volatilization, and in the case of absorbent articles with fragrance, the fragrance is kept low before use, and the fragrance is strongly generated from use to after use, masking and harmonization effect This is because it is a quality requirement to issue
- the simplest technique is to directly apply the fragrance included in cyclodextrin to the absorbent body in the processing step of the absorbent article.
- the inclusion reaction solution of the fragrance and cyclodextrin is dried to volatilize the non-inclusion fragrance, and the remaining fragrance inclusion compound powder is recovered. Then, in the manufacturing process of the absorbent article, there is a method in which the absorbent article is directly added to the absorbent body or mixed with an oil-based solvent and applied (see Patent Document 1 below).
- Patent Document 2 there is a method for making a perfume-impregnated hydrogel-forming absorbent polymer in which the release of aroma is resolved by the dynamic wetting force of the polymer when the polymer is wet, i) mixing the solid carrier and perfume with the reaction intermediate product of the hydrogel-forming absorbent polymer before the polymerization gel point of the hydrogel-forming absorbent polymer; (ii) the perfume-impregnated hydrogel-forming absorbent.
- a method comprising the step of forming a polymer, and (iii) drying the perfume-impregnated hydrogel-forming absorbent polymer.

- the main problem of the present invention is to provide an absorbent article and a method for producing the same, which can improve the contact efficiency between the fragrance and the body fluid, enable the fragrance to be generated effectively with a small amount of fragrance, and simplify the production process. There is.
- the present invention according to claim 1 is an absorbent article comprising an absorbent body obtained by defibrating a pulp raw sheet and stacking the pulverized pulverized pulp, An absorbent article is provided in which a fragrance is added to the original pulp sheet before defibration.
- a fragrance is added in advance to the original pulp sheet before defibration, the pulp original sheet to which this fragrance has been added is defibrated, and the pulverized pulp is defibrated. Since the absorbent body is manufactured, the fragrance is dispersed almost uniformly throughout the absorbent body, so that the contact efficiency between the fragrance and the body fluid increases during use, and the fragrance is effectively emitted with a small amount of the fragrance. Become.
- the absorptivity according to claim 1 wherein the perfume is encapsulated in an inclusion material comprising at least one selected from the group consisting of cyclodextrin, xanthan gum, guar gum and pectin. Articles are provided.
- An absorbent article manufacturing method comprising: an absorbent article processing step in which a sheet is defibrated and the pulverized pulverized pulp is piled to produce an absorbent body.
- the invention of claim 3 is a first embodiment in which a fragrance is added to a pulp original fabric sheet, and a fragrance is added to the wet paper after forming the wet paper. Thereafter, the pulp raw fabric sheet to which the fragrance is added in the processing step of the absorbent article is defibrated, and the fragrance is added to the whole of the absorber by stacking the pulverized pulverized pulp to produce the absorbent. It spreads almost uniformly, and the contact efficiency between the fragrance and the body fluid is increased during use, and the fragrance can be effectively emitted with a small amount of fragrance.
- the wet paper is dried in the paper making process and the unwrapped fragrance is volatilized, it is not necessary to separately provide a drying process and a recovery process in the process of blending the fragrance, and the manufacturing process can be simplified.
- the perfume when the wet paper is formed by a multi-layered circular paper machine, the perfume is added to a paper layer serving as an intermediate layer among the paper layers laminated in multiple layers.
- a method for producing an absorbent article according to claim 3 is provided.
- the perfume is added to the paper layer serving as an intermediate layer among the wet paper made of a plurality of paper layers.
- the paper layer of the surface layer covers each side of the intermediate layer to which the fragrance is added, so that the volatilization of the fragrance is suppressed, and the fragrance is transferred to the papermaking felt so that the fragrance is lost or attached to the next product. Can be prevented.
- the invention according to claim 5 is a second embodiment in which a fragrance is added to a pulp original fabric sheet, in which a fragrance is mixed with a raw material in advance and a wet paper is formed from the raw material mixed with the fragrance. is there.
- the perfume when the wet paper is formed by a multi-layered circular paper machine, the perfume is used as a raw material for forming a paper layer serving as an intermediate layer among the multi-layered paper layers.
- the manufacturing method of the absorbent article of Claim 5 currently mixed is provided.
- a perfume is mixed with the raw material of the wet paper as the intermediate layer among the wet paper made of a plurality of paper layers.
- An absorbent article manufacturing method comprising: a pulp original fabric sheet is defibrated, and the fibrillated pulverized pulp is piled to produce an absorbent article.
- the invention according to claim 7 is a third embodiment in which a fragrance is added to a pulp original sheet, and the fragrance is added to the pulp original sheet immediately after defibrating after producing the pulp original sheet by a normal papermaking process. Is added.
- the contact efficiency between the fragrance and the body fluid is increased, the fragrance can be effectively generated with a small amount of the fragrance, and the manufacturing process can be simplified.
- the absorbent article according to the present invention comprises a cotton-like pulp between a liquid-permeable top sheet made of a perforated or non-porous nonwoven fabric or a perforated plastic sheet and a liquid-impervious leak-proof sheet made of polyethylene or the like.
- a disposable diaper, a urine collection pad, an incontinence pad, a sanitary napkin, etc. can be exemplified.
- the absorbent body is constituted by defibrating the pulp original fabric sheet obtained in the paper making process and stacking the defibrated pulverized pulp, and the pulp before defibration.
- the fragrance is added to the absorber.
- the fragrance it is preferable to use a fragrance that emits a scent only upon contact with a body fluid and hardly scents before contact.
- the fragrance component itself reacts with moisture to smell.
- a material that emits fragrance a material in which a fragrance is included in an inclusion material, or the like.
- the fragrance while preventing the loss of fragrance due to volatilization, the fragrance is kept low before use, the fragrance is strongly generated from use to after use, and the absorption with scent that emits masking and harmonized effect
- the fragrance is included in the inclusion substance. This fragrance is added to the absorber by a predetermined method.
