【発明の詳細な説明】 （産業上の利用分野） 本発明は紙おむつ、生理用ナプキン、産褥パツドなどの
吸収性物品に関する。更に詳しくは、吸収材の強度が強
く、しかも鋭臭能を備えている吸収性物品に関する。TECHNICAL FIELD The present invention relates to absorbent articles such as disposable diapers, sanitary napkins, and postpartum pads. More specifically, the present invention relates to an absorbent article in which the strength of the absorbent material is high and the odor is sharp.
（発明の背景） 使い捨ておむつなどの吸収性物品の吸収材には、周知の
通り、綿状パルプ又はこれと高吸水性ポリマーを吸水紙
で被覆したものが用いられるようになつてきている。最
近では、持ち運び、装着性などの点から、できるだけ小
さく薄くコンパクトにする工夫がなされてきている。(Background of the Invention) As is well known, absorbent cotton for absorbent articles such as disposable diapers has been made of cotton-like pulp or super absorbent polymer covered with absorbent paper. Recently, in terms of portability and wearability, efforts have been made to make it as small and thin as possible.
しかし、この場合、綿状パルプなどの吸収材の使用量を
減少せざるを得ないため、吸収材の強度が低下し、使用
時に破れたり、裂け目がはいつたりして、尿などのもれ
の原因にもなつており、問題の解決が望まれていた。However, in this case, the amount of absorbent material such as cotton pulp must be reduced, so the strength of the absorbent material is reduced, and the absorbent material may be torn or ruptured during use, resulting in leakage of urine, etc. It is also a cause of, and the solution of the problem was desired.
また、使い捨て紙おむつ、生理用パツドでは、体内から
の排泄物を吸収すると、それぞれ特有な不快な臭気が発
生する。尿の場合、尿中の尿素、アミン酸などが微生物
分解によりアンモニアどに変化し、周知の通り、独特な
不快な臭気を発生する。また、生理臭についても、排泄
されるアミン酸などが微生物分解されることにより発生
すると考えられている。In addition, in disposable paper diapers and sanitary pads, when excretions from the body are absorbed, peculiar unpleasant odors are generated. In the case of urine, urea, amine acid, etc. in the urine are changed into ammonia and the like by microbial decomposition, and as is well known, a peculiar unpleasant odor is generated. In addition, it is considered that physiological odor is also generated by microbial decomposition of excreted amine acid and the like.
従来、これらの臭気防止を図る手段として、活性炭ゼオ
ライトを使用するなどの方法が提案されているが、価格
が高くなるなど、まだ満足すべきものはない。Heretofore, methods such as using activated carbon zeolite have been proposed as a means for preventing these odors, but there is still nothing to be satisfied such as an increase in price.
（発明の目的） 上記の様な問題点を解決すべく、本発明者らは鋭意検討
の結果、ジアルデヒドデンプンが吸収材の強度向上ばか

のに、極めて効果のあることを見い出し、本発明に到達
した。(Object of the invention) In order to solve the above problems, as a result of intensive studies by the present inventors, the dialdehyde starch not only improves the strength of the absorbent, but also prevents odor such as urine excreted from the body. However, they have found that they are extremely effective, and have reached the present invention.
（発明の構成） 本発明は吸水紙及び／又は吸収材中にジアルデヒドデン
プンを含有せしめてなる吸収性物品である。(Structure of Invention) The present invention is an absorbent article in which dialdehyde starch is contained in a water-absorbent paper and / or absorbent material.
ジアルデヒドデンプンは、デンプンを過沃素酸で酸化し
て、種々の酸化度のものが得られ、これらが脱臭能を持
つデンプンとして使用可能である。例えば、日本カーリ
ット（株）・カルダスなどがあげられる。Dialdehyde starch can be used as starch having a deodorizing ability by oxidizing starch with periodic acid to obtain those having various degrees of oxidation. For example, Nippon Carlit Co., Ltd., Caldas, etc. are mentioned.

パルプや液体の吸収性を向上させる高分子吸水剤の粉体
をフラツフパルプ等に混入したものや、粉体を層状に配
置したシート等が使用出来る。As the liquid absorbing material, any of those which are usually used in diapers and daily napkins can be used. For example, it is possible to use a thin paper laminate such as Teisyu paper, a mixture of flat pulp or a powder of a polymer water-absorbing agent for improving the absorbency of liquid in the flat pulp, a sheet in which the powder is arranged in layers, and the like.
吸水紙へのジアルデヒドデンプンの添加は、吸水紙の製
造工程中にその原料に添加してもよく、また、紙に溶液
状のジアルデヒドデンプンをスプレー添加し、熱ロール
などで乾燥してもよい。The addition of dialdehyde starch to the water-absorbent paper may be added to the raw material during the production process of the water-absorbent paper, or the solution-form dialdehyde starch may be spray-added and dried on a hot roll or the like. Good.
吸水紙に対してジアルデヒドデンプンを０．１〜０．５
％加えるだけで、強度はかなり向上し、強い吸収材をつ
くることが可能となる。Add 0.1 to 0.5 of dialdehyde starch to absorbent paper
%, The strength is considerably improved, and it becomes possible to make a strong absorber.
また、綿状パルプについては、ジアルデヒドデンプン水
溶液を散布した後、熱ロールで乾燥、圧縮すると、容易

すとともに、尿等から発生するアンモニア臭などを防ぐ
ことができる。For cotton-like pulp, an absorbent material having excellent strength and deodorizing ability can be easily obtained by spraying an aqueous solution of dialdehyde starch and then drying and compressing with a hot roll. Similar to the water-absorbent paper, by adding 0.1 to 0.5% (to pulp), it is possible to bring about a great strength improving effect and prevent ammonia odor and the like generated from urine and the like.
高吸水性ポリマーに含有させる場合には、粉末の形で混
合することが望ましい。この場合、吸収材料の強度を向
上させる効果は期待できない。When it is contained in the superabsorbent polymer, it is desirable to mix it in the form of powder. In this case, the effect of improving the strength of the absorbent material cannot be expected.
ジアルデヒドデンプンは吸水紙、綿状パルプ、高吸水性
ポリマーのいずれに添加してもよいが、強度の向上と脱
臭能の付与という両方の効果を期待する上からは、吸水
紙あるいは綿状パルプのいずれか、または両者に添加す
ることが望ましい。Dialdehyde starch may be added to any of water-absorbent paper, cotton-like pulp, and superabsorbent polymer, but from the viewpoint of expecting both effects of improving strength and imparting deodorizing ability, water-absorbent paper or cotton-like pulp is preferred. It is desirable to add to either or both.
ジアルデヒドデンプンにより強度が向上する機構につい

れる。Although the mechanism by which the strength of the dialdehyde starch is improved is not clear, it is known that the hydroxyl groups present in water-absorbent paper and cotton pulp and the aldehyde groups of the dialdehyde starch form a hemiacetal bond or an acetal bond. It seems that the strength is improved by this. In addition, regarding the mechanism of removing malodor, although it does not go beyond the presumed range, it may be possible that dialdehyde starch and urea, amino acids, ammonia, etc. in excretions from the body combine to inactivate it. Conceivable.
以下、実施例に基づき、本発明を更に詳しく説明する。Hereinafter, the present invention will be described in more detail based on examples.
