Description
本発明は、茶ポリフェノールを有効成分とする吸収性向上剤に関する。 The present invention relates to an absorbability improver containing tea polyphenol as an active ingredient.
繊維や紙類などの吸水性を向上させる方法としては、高吸水性高分子を用いる方法が知られており、例えば紙おむつや生理用品などの吸収体に広く用いられている。かかる高吸水性高分子は、数百倍から約千倍までの水を吸収・保持することができるためその機能性に優れている。 As a method for improving the water absorption of fibers and papers, a method using a super absorbent polymer is known, and is widely used for absorbent bodies such as disposable diapers and sanitary products. Such a super absorbent polymer is excellent in its functionality because it can absorb and retain water from several hundred times to about 1,000 times.
かかる高吸水性高分子を用いた吸収体は使い捨てのような製品に向いており、日常生活にも浸透している。しかしながら、かかる吸収体の用途とは別に、日常生活レベルで繰り返し使用するような類の吸収体には、かかる高吸水性高分子は向いているとは言い難い。 Absorbents using such super absorbent polymers are suitable for products such as disposable products, and have penetrated into daily life. However, apart from the use of such an absorber, it cannot be said that such a super absorbent polymer is suitable for an absorber of the kind that is repeatedly used at the level of daily life.
一例を挙げるとすると、日常生活には欠かせないタオル類は、その性質上、優れた吸収性が求められるものである。しかしながら、タオル類を使い捨てにするようなことはないため、高吸水性高分子を使用することは現実的でない。さらに言えば、タオル類は、使用の都度、洗濯に供される場合が多いものの、かかる高吸水性高分子では、毎回のこのような洗濯に耐え得るようなものではない。 As an example, towels, which are indispensable for daily life, are required to have excellent absorbency due to their nature. However, it is not realistic to use a super absorbent polymer because towels are not disposable. Furthermore, although towels are often used for washing each time they are used, such superabsorbent polymers are not capable of withstanding such washing each time.
すなわち、日常生活において繰り返しの洗浄や洗濯に適した、繊維や紙類などの吸水性を向上させる方法が求められていた。 That is, there has been a demand for a method for improving the water absorption of fibers and papers, which is suitable for repeated washing and washing in daily life.
ところで、茶ポリフェノールは様々な作用効果を有することは広く知られており、その作用効果には様々な種類がある。例えば、動脈硬化や脳梗塞を防ぐ抗酸化作用、ホルモン促進作用などの生理活性機能や、抗菌性や消臭性などのサニタリー機能に関するものを挙げることができる。 By the way, it is widely known that tea polyphenols have various actions and effects, and there are various kinds of actions and effects. For example, those related to physiologically active functions such as antioxidant action and hormone promoting action to prevent arteriosclerosis and cerebral infarction, and sanitary functions such as antibacterial action and deodorant action can be mentioned.
これらと少し軌を異にするものとしては、例えば特許文献1は、衛生用基紙に所定量の茶ポリフェノール、グリセリン及びポリエチレングリコールを塗布又は含浸させることにより保湿紙の柔らかさを向上させる方法を提案している。
しかしながら、茶ポリフェノールが被接触物の吸収性を向上させること、とりわけ溶媒を介して茶ポリフェノールと接触させることにより、被接触物の吸収性を向上することは知られていなかった。
As a method slightly different from these, for example, Patent Document 1 describes a method of improving the softness of a moisturizing paper by applying or impregnating a predetermined amount of tea polyphenol, glycerin and polyethylene glycol on a sanitary base paper. is suggesting.
However, it has not been known that tea polyphenols improve the absorbability of the material to be contacted, especially by contacting the tea polyphenol with a solvent.
本発明は、簡便な方法により被接触物、とりわけ繊維における吸収性を向上させることを目的とする。 An object of the present invention is to improve the absorbability of a contacted object, particularly a fiber, by a simple method.
本発明は、茶ポリフェノールと接触させることにより、被接触物、とりわけ繊維における吸収性が向上することを見出し、本発明を完成するに至った。 The present invention has been found that contact with tea polyphenols improves the absorbability of the contacted material, particularly the fiber, and has completed the present invention.

Test 1: Absorption improvement effect by catechin (washing treatment)
A commercially available towel cloth was washed with water containing catechins (using Teafran 30A, manufactured by Itoen Co., Ltd.) by stirring for 5 minutes, and then rinsed with pure water for 5 minutes. Then, the towel cloth was dehydrated and then dried at 105 ° C. The amount of theafran 30A to be blended was set to 0% owf, 1% owf, 5% owf, and 10% owf, and the presence or absence of variation depending on the amount of catechin was examined. In addition, the sample in which the blending amount of the tea franc 30A is 0% owf corresponds to the control.
(吸水時間の測定)
次に、タオル生地表面にマイクロピペットで水を滴下し、滴下した水滴がタオル生地に全て吸収されるまでの時間を測定した。なお、各サンプルの試験は5回実施し、得られた測定時間の平均値を算出して吸水時間(秒)とした。
(Measurement of water absorption time)
Next, water was dropped on the surface of the towel cloth with a micropipette, and the time until all the dropped water drops were absorbed by the towel cloth was measured. The test of each sample was carried out 5 times, and the average value of the obtained measurement times was calculated and used as the water absorption time (seconds).
(考察)
カテキン類を含有しない水で洗濯した場合、吸水時間の平均値は18.0秒であった(サンプル1)。これに対して、カテキン類を含有する水で洗濯した場合であって、テアフラン30Aの添加量が1%o.w.fである場合、平均値は8.5秒であった(サンプル2)。また、テアフラン30Aの添加量が5%o.w.fである場合、平均値は4.1秒であった(サンプル3)。さらに、テアフラン30Aの添加量が10%o.w.fである場合、平均値は3.9秒であった(サンプル4)。
以上から、カテキン類を含有する水で洗濯した場合の方が、カテキン類を含有しない水で洗濯した場合と比較して、タオル生地の吸収性がいずれも高まったことがわかった。また、カテキン類を含有する水で洗濯した場合、カテキン類の濃度が高いと吸収性が高くなる傾向にあることがわかった。
なお、水とエタノールを1:1に混合した50%エタノールにカテキン類(テアフラン30A、伊藤園社製)を含有させた試験も併せて実施した。50%エタノールを使用する以外は試験1と同様に実施した。結果、吸水性について水を用いた試験と同様の傾向を示すことがわかった。
(Discussion)
When washed with water containing no catechins, the average water absorption time was 18.0 seconds (Sample 1). On the other hand, when the clothes were washed with water containing catechins and the amount of theafran 30A added was 1% owf, the average value was 8.5 seconds (Sample 2). When the amount of Tearfran 30A added was 5% owf, the average value was 4.1 seconds (Sample 3). Further, when the addition amount of theafran 30A was 10% owf, the average value was 3.9 seconds (Sample 4).
From the above, it was found that the absorbability of the towel cloth was higher in the case of washing with water containing catechins than in the case of washing with water containing no catechins. It was also found that when washed with water containing catechins, the higher the concentration of catechins, the higher the absorbability.
A test was also conducted in which catechins (Tearfran 30A, manufactured by Itoen Co., Ltd.) were contained in 50% ethanol, which was a 1: 1 mixture of water and ethanol. The procedure was the same as in Test 1 except that 50% ethanol was used. As a result, it was found that the water absorption showed the same tendency as the test using water.

試験3:化学繊維における吸収性向上効果
(洗濯処理)
市販のタオル生地の代わりに化学繊維の布を用いて、試験1と同様の試験を実施した。試験に供した化学繊維は、レーヨン60%とポリエステル40%からなる不織布サンプルであり、テアフラン30A量の配合量が0%o.w.fであるサンプル(No.26)がコントロールに相当する。
各サンプル試験は5回実施し、得られた測定時間の平均値を算出して吸水時間(秒)とした。
Test 3: Absorption improving effect on chemical fibers (washing treatment)
The same test as in Test 1 was carried out using a cloth made of chemical fibers instead of a commercially available towel cloth. The chemical fiber used in the test was a non-woven fabric sample composed of 60% rayon and 40% polyester, and the sample (No. 26) in which the amount of theafran 30A was 0% owf corresponds to the control.
Each sample test was carried out 5 times, and the average value of the obtained measurement times was calculated and used as the water absorption time (seconds).
(考察)
カテキン類を含有しない水で洗濯した場合、吸水時間は17秒であった(サンプル26)。これに対して、カテキン類を含有する水で洗濯した場合であって、テアフラン30Aの添加量が1%o.w.fである場合、吸水時間は13秒であった(サンプル27)。また、テアフラン30Aの添加量が5%o.w.fである場合、吸水時間は10秒であった(サンプル28)。さらに、テアフラン30Aの添加量が10%o.w.fである場合、吸水時間は6秒であった(サンプル29)。
以上から、試験1と同様、カテキン類を含有する水で洗濯した場合の方が、カテキン類を含有しない水で洗濯した場合と比較して、タオル生地の吸収性がいずれも高まったことがわかった。また、カテキン類を含有する水で洗濯した場合、カテキン類の濃度が高いと吸収性が高くなる傾向にあることがわかった。また、吸水性が高い素材をカテキン類を含有する水で洗濯した場合、吸収性が更に向上することが明らかとなった。
また、本発明における効果は、タオル生地のみならず化学繊維でも同様の効果が得られるため、繊維の素材や該繊維の付着物に影響されるものではないことも明らかになった。
(Discussion)
When washed with water containing no catechins, the water absorption time was 17 seconds (Sample 26). On the other hand, when the clothes were washed with water containing catechins and the amount of theafran 30A added was 1% owf, the water absorption time was 13 seconds (Sample 27). When the amount of theafran 30A added was 5% owf, the water absorption time was 10 seconds (Sample 28). Further, when the addition amount of theafran 30A was 10% owf, the water absorption time was 6 seconds (sample 29).
From the above, it was found that, as in Test 1, the absorbability of the towel cloth was higher when washed with water containing catechins than when washed with water containing no catechins. It was. It was also found that when washed with water containing catechins, the higher the concentration of catechins, the higher the absorbability. Further, it was clarified that when a material having high water absorption was washed with water containing catechins, the absorbability was further improved.
Further, it was clarified that the effect in the present invention is not affected by the material of the fiber or the deposit of the fiber because the same effect can be obtained not only with the towel cloth but also with the chemical fiber.
