Description

本発明は、ティシュペーパーのようにたとえば200組折り畳んで包材に内包されて製品とされ、使用に際しては、必要によりホルダー容器に移し替えされ、そのホルダー容器から1シートごと取り出して使用される古紙含有ペーパータオルに関するものである。   In the present invention, for example, 200 sets of tissue paper are folded and encased in a packaging material to obtain a product. When used, the used paper is transferred to a holder container as needed, and is used by taking out one sheet from the holder container. Containing paper towels.

ペーパータオルとしては、主に、手拭き時の(水分)吸収性、手肉感及びホルダー容器からの脱落防止を課題として設計される。
このために、ウエットクレープ加工によりしっかりと紙質のシートされている。なお、柔軟性を高めるための手法としては、特許文献1の提案がなされているが、古紙パルプを使用するものではない。
一方、環境意識に高まりに対応して、古紙パルプを使用したペーパータオルが要求されている。古紙パルプを使用したペーパータオル自体は特許文献2に記載がある。
古紙パルプを使用する場合において問題となるのは、パルプ繊維長が短いために、紙力が小さく、高い吸収性及び良好な手肉感を得難いことである。
特開2006−97191号公報 特開平11−164793号公報
The paper towel is mainly designed with the issues of (moisture) absorption during hand wiping, hand feeling and prevention of falling out of the holder container.
For this reason, the paper is firmly formed by wet creping. In addition, as a method for improving flexibility, Patent Document 1 has been proposed, but waste paper pulp is not used.
On the other hand, paper towels using waste paper pulp are required in response to growing environmental awareness. Patent Document 2 discloses a paper towel itself using waste paper pulp.
A problem in using waste paper pulp is that the pulp fiber length is short, so that the paper strength is small, and it is difficult to obtain high absorbency and good hand feeling.
JP 2006-97191 A JP-A-11-164793

そこで、本発明の主たる課題は、100%古紙パルプを使用するものの、手拭き時の(水分)吸収性、手肉感及びホルダー容器からの脱落防止効果を示すものを提供することにある。   Therefore, the main object of the present invention is to provide a material that exhibits 100% waste paper pulp and exhibits (moisture) absorptivity during hand wiping, hand feeling, and a drop-off preventing effect from the holder container.

上記課題を解決した本発明は次記のとおりである。
<請求項1記載の発明>
1プライ当たりの米坪が30〜50g/m2、古紙パルプを90〜100%含有し、平均繊維長が0.7〜1.5mmのパルプ原料を抄紙したものであり、湿潤紙力剤及び乾燥紙力剤をそれぞれ前記パルプ原料に対し0.10〜0.30質量%含有され、かつ、湿潤紙力剤/乾燥紙力剤の質量比が0.5〜1.5であり、ドライクレープが施されていることを特徴とする古紙含有ペーパータオル。
The present invention that has solved the above problems is as follows.
<Invention of Claim 1>
A paper raw material containing 30 to 100 g / m 2 of rice basis weight, 90 to 100% of waste paper pulp, and having an average fiber length of 0.7 to 1.5 mm is obtained. A dry paper strength agent is contained in an amount of 0.10 to 0.30% by mass with respect to the pulp raw material, respectively, and the mass ratio of wet paper strength agent / dry paper strength agent is 0.5 to 1.5. A paper towel containing used paper, characterized in that

(作用効果)
本発明のペーパータオルは、平均繊維長が0.7〜1.5mmの古紙パルプを90〜100%含有する。紙力を増強するために、パルプ原料に対しポリアクリルアミド・エピクロルヒドリン樹脂に代表される湿潤紙力剤を、パルプ原料に対し0.10〜0.30質量%添加する。湿潤紙力剤の添加量が少ない場合は、湿潤強度が不十分であり、他方で過度の添加量では吸水特性が低下する。
繊維長が長いバージンパルプを使用する場合には、特許文献1のように湿潤紙力剤の添加のみで十分の紙力を得るのは容易である。これに対し、平均繊維長が0.9〜1.1mmの古紙パルプを、特に100%現有させる場合、紙力が十分でなく、特に乾燥時における表面における強度が低いものとなり、紙粉の発生などを生じる。
そこで、本発明では、乾燥紙力剤をパルプ原料に対し0.10〜0.30質量%添加して表面を強度高まる。
しかるに、前述のように、ペーパータオルとして手拭き時の(水分)吸収性及び手肉感が良好であることが要求されるところ、紙力を高めるために、かなり多い量(通常は湿潤紙力剤のみをパルプ原料に対し0.05〜0.08質量%程度である。)で湿潤紙力剤及び乾燥紙力剤を添加すると、手拭き時の(水分)吸収性及び手肉感が損なわれ、嵩高感のないものなる。
そこで、ウエットクレープによることなくドライクレープ加工を採用することで、手拭き時の(水分)吸収性、嵩高感及び手肉感を優れるものとしたのである。
なお、本発明において所要の吸収量を確保するために、1プライ当たりの米坪が30〜50g/m2とした。通常は、2プライをエンボス加工により一体化させて製品シートとする。
(Function and effect)
The paper towel of the present invention contains 90 to 100% of waste paper pulp having an average fiber length of 0.7 to 1.5 mm. In order to enhance paper strength, 0.10 to 0.30 mass% of wet paper strength agent represented by polyacrylamide / epichlorohydrin resin is added to the pulp material. When the addition amount of the wet paper strength agent is small, the wet strength is insufficient. On the other hand, when the addition amount is excessive, the water absorption property is lowered.
When virgin pulp having a long fiber length is used, it is easy to obtain a sufficient paper strength only by adding a wet paper strength agent as in Patent Document 1. On the other hand, when used paper pulp having an average fiber length of 0.9 to 1.1 mm, especially 100%, the paper strength is not sufficient, and the strength on the surface particularly during drying is low, and paper dust is generated. And so on.
Therefore, in the present invention, the strength of the surface is increased by adding 0.10 to 0.30 mass% of the dry paper strength agent to the pulp raw material.
However, as described above, when paper towels are required to have good (water) absorbency and hand feeling when wiping, a large amount (usually only wet paper strength agent is used to increase paper strength. When the wet paper strength agent and the dry paper strength agent are added at about 0.05 to 0.08 mass% with respect to the pulp raw material, the (moisture) absorbability and hand feeling at the time of hand wiping are impaired, and the bulkiness is increased. It will not be.
Therefore, by adopting dry crepe processing without using wet crepe, (water) absorbability, bulkiness and hand feeling at the time of hand wiping are excellent.
In the present invention, in order to ensure the required amount of absorption, the rice basis weight per ply was set to 30 to 50 g / m 2 . Usually, two plies are integrated by embossing to form a product sheet.

<請求項2記載の発明>
クレープ率が15〜20%である請求項1記載の古紙含有ペーパータオル。
<Invention of Claim 2>
The used paper towel according to claim 1, wherein the crepe rate is 15 to 20%.

(作用効果)
クレープ率としては、13〜22%、特に15〜20%が望ましい。クレープ率が低いと、シート表面が平滑化の方向となるため、表面積が小さくなり、吸水特性が小さくなり、しかも必要な嵩高感及び手肉感を得難い。逆に、22%を超えると、嵩高になるため、吸水特性は向上するものの、ホルダー容器から引き出すとき破れの原因となる。
(Function and effect)
The crepe rate is preferably 13 to 22%, particularly preferably 15 to 20%. When the crepe rate is low, the surface of the sheet is in a smoothing direction, the surface area is reduced, the water absorption characteristics are reduced, and the necessary bulkiness and hand feeling are difficult to obtain. On the other hand, if it exceeds 22%, it becomes bulky, so that the water absorption property is improved, but when it is pulled out from the holder container, it causes tearing.

<請求項3記載の発明>
吸水量が150〜300g/m2である請求項1または2項に記載の古紙含有ペーパータオル。
<Invention of Claim 3>
Waste paper containing paper towel of claim 1 or 2, wherein water absorption is 150 to 300 g / m 2.

(作用効果)
この吸水量は市販品(古紙パルプを使用しないバージンパルプ品)と比較しても、湿潤紙力剤及び乾燥紙力剤を添加するものでありながら、高い値を示す。これは、ウエットクレープによることなくドライクレープ加工によることに基因しているものと考えられる。
(Function and effect)
Even if this water absorption amount adds a wet paper strength agent and a dry paper strength agent compared with a commercial item (virgin pulp product which does not use waste paper pulp), it shows a high value. This is considered to be based on dry creping rather than wet creping.

本発明によれば、古紙パルプを90〜100%含有するものを使用するものの、手拭き時の(水分)吸収性、手肉感及びホルダー容器からの脱落防止効果を示す古紙含有ペーパータオルを得ることができる。   According to the present invention, a paper towel containing used paper pulp containing 90 to 100% can be obtained, and a used paper towel that exhibits (moisture) absorbency during hand wiping, hand feeling and prevention of falling out of the holder container can be obtained. .

以下、本発明の一実施形態について詳説する。
本発明の古紙含有ペーパータオルは、古紙パルプを90〜100%含有する。より好ましくは古紙パルプ100%のものである。古紙パルプとしては、デインキングパルプ(DIP)の何れをも使用できる。古紙パルプの原料には、例えば上白、罫白、カード、特白、中白、模造、ケント、白アート、新聞、雑誌等があげられる。これらのパルプを2種以上用いてもよい。
Hereinafter, an embodiment of the present invention will be described in detail.
The used paper-containing paper towel of the present invention contains 90-100% of used paper pulp. More preferably, the waste paper pulp is 100%.

Two or more of these pulps may be used.

資材の有効利用のために、雑誌古紙脱墨パルプを使用するのが望ましい。雑誌古紙脱墨パルプの繊維長は、操業条件によるが、平均繊維長が0.7〜1.5mmである。雑誌古紙パルプの特徴は、新聞古紙パルプなどの通常の古紙パルプが機械パルプを5〜10%程度含むのに対し、機械パルプを20〜30%程度含み紙力が弱い原因となることである。しかるに、本発明に従えば、雑誌古紙脱墨パルプを使用したとしても、特性に優れた古紙含有ペーパータオルを得ることができる。   It is desirable to use waste magazine deinked pulp for effective use of materials. The fiber length of the magazine waste paper deinked pulp depends on the operating conditions, but the average fiber length is 0.7 to 1.5 mm. The feature of magazine waste paper pulp is that normal waste paper pulp such as newspaper waste paper pulp contains about 5 to 10% mechanical pulp, while it contains about 20 to 30% mechanical pulp and causes a weak paper strength. However, according to the present invention, even if the used magazine deinked pulp is used, it is possible to obtain a used paper towel with excellent properties.

本発明では、古紙パルプ原料スラリーを、好適には、カナディアンスタンダードフリーネスが、280〜350mlになるように調整され、湿潤紙力剤及び乾燥紙力剤をそれぞれパルプ原料に対し0.10〜0.30質量%含有するように添加し、円網抄紙機、短網抄紙機などにより抄紙する。
その際に、1プライ当たりの米坪が30〜50g/m2とする。抄紙機のドライヤー出口にドライクレープ加工する。クレープ率は13〜22%が望ましい。

It is added so as to contain 30% by mass, and paper is made with a circular paper machine or a short paper machine.
In that case, the rice tsubo per 1 ply shall be 30-50 g / m < 2 >. Dry crepes are processed at the dryer outlet of the paper machine. The crepe rate is desirably 13 to 22%.

本発明で使用する湿潤紙力剤としては、ポリアクリルアミド・エピクロルヒドリン樹脂、ポリアミド樹脂、ポリアミド・エピクロルヒドリン樹脂、ポリアミド・ポリアミン・エピクロルヒドリン樹脂などを使用できるが、ポリアミド・エピクロルヒドリン樹脂が好適である。   As the wet paper strength agent used in the present invention, polyacrylamide / epichlorohydrin resin, polyamide resin, polyamide / epichlorohydrin resin, polyamide / polyamine / epichlorohydrin resin and the like can be used, and polyamide / epichlorohydrin resin is preferable.

本発明で使用する乾燥紙力剤としては、アニオン性ポリアクリルアミド、PAM、澱粉、カチオン性ポリアクリルアミドなどを使用できるが、カチオン性ポリアクリルアマイドが好適である。
湿潤紙力剤/乾燥紙力剤の質量比はより望ましくは、0.6〜1.5である。
As the dry paper strength agent used in the present invention, anionic polyacrylamide, PAM, starch, cationic polyacrylamide and the like can be used, and cationic polyacrylamide is preferable.
The mass ratio of wet paper strength agent / dry paper strength agent is more desirably 0.6 to 1.5.

本発明によれば、吸水量が150〜300g/m2である製品を得ることができる。この場合に吸水量は、シートにある一定の時間の間に浸み込み、保水した時の水の量を計測することによって測定できるものである。 According to the present invention, a product having a water absorption of 150 to 300 g / m 2 can be obtained. In this case, the amount of water absorption can be measured by soaking in the sheet for a certain period of time and measuring the amount of water when the water is retained.
