Description

本発明は、塩素等による漂白処理がされていない家庭用薄葉紙に関し、特にキッチンペーパー等に使用される無漂白のペーパータオルに関する。   The present invention relates to a household thin paper that is not bleached with chlorine or the like, and more particularly to an unbleached paper towel used for kitchen paper or the like.

ペーパータオルは、下記文献にも示されるとおり、食材や食器についた水分、油分の拭取り、揚げ物などの過剰油分の吸い取り、使用後の油こし等に用いられるキッチンペーパー、飲食店等の店舗における使い捨て手拭用タオルなどに用いられる。ペーパータオルは、塩素漂白など各種の方法で漂白処理された漂白パルプのみを原料とするもの、非常に安価なNUKP(漂白処理をしていない針葉樹パルプをいう。以下、同じ)を原料とするものがあるが、NUKPを原料とするペーパータオルは、漂白パルプを利用したペーパータオルと比較して白色度が格段に低く(通常は濃い茶色を呈しているものがほとんどである)、また柔らかさに劣るため、これまではNUKPを原料とするペーパータオルよりも漂白パルプを利用したペーパータオルのほうが格段に需要者に好まれる傾向にあった。特に、キッチンペーパー用途についてはこの傾向が顕著であった。そして、NUKPを利用したペーパータオルは、主に高品質を必要としない用途、例えば大量消費される使い捨て手拭用タオル等としての需要がほとんどであった。   Paper towels are disposable in stores such as kitchen paper and restaurants used to wipe off excess oil such as fried foods, wipe off excess oil such as fried foods, as well as the following literature. Used for hand towels. Paper towels are made only from bleached pulp that has been bleached by various methods such as chlorine bleaching, and are made from very cheap NUKP (which means softwood pulp that has not been bleached; hereinafter the same). However, paper towels made from NUKP are much less white than paper towels using bleached pulp (usually most of them are dark brown), and are inferior in softness. So far, paper towels using bleached pulp have tended to be favored by consumers more than paper towels made from NUKP. In particular, this tendency was remarkable for kitchen paper applications. The paper towels using NUKP are mostly in demand for applications that do not require high quality, such as disposable towels for mass consumption.

しかし、近年では、漂白処理工程で使用する塩素が有害物質であるダイオキシン類の発生原因となることが指摘され、また、昨今の天然素材を原料とする製品が流行していることから、特に食材あるいは肌に直接触れる用途において、塩素等の漂白剤を使用していな未晒パルプを原料とするペーパータオルを使用したいとの要求が需要者の間で高まってきている。他方、飲食店等の店舗における使い捨て手拭用タオルの使用が一般的になりつつあり需要が急増してきたことから、これまで求められなかった柔らかさなどの製品の品質向上が求められるようになってきた。

However, in recent years, it has been pointed out that chlorine used in the bleaching process is a cause of the generation of dioxins, which are harmful substances, and products made of natural materials as a raw material have become popular, so foodstuffs in particular Alternatively, in applications that directly touch the skin, there is an increasing demand among customers for using paper towels made from unbleached pulp that does not use bleach such as chlorine. On the other hand, the use of disposable towels in restaurants and other stores is becoming more common, and demand has increased rapidly, so it has become necessary to improve the quality of products such as softness, which has not been required so far. It was.
JP 2002-046245 A JP2001-159089 JP-A-11-093095 JP 2002-327398 A JP-A-11-189959

しかし、上述のようにNUKPを原料とする従来のペーパータオルは、白色度が極めて低い。各種の拭取りに用いられるペーパータオルでは、ペーパータオル表面に付着した被拭取り物の状態を目視にて確認することにより、拭取りが行われたか不十分であったかを判断するのが一般的であり、白色度が高いほうがかかる確認をしやすいため、ペーパータオルでは高白色度であることが一般的には望まれる。しかし、需要者は、一般的に白いと感じるほどの高白色度のペーパータオルよりも、茶色を呈するペーパータオルのほうが天然素材である感じを受け、このような製品を漂白処理されていないペーパータオルとして好む傾向にある。したがって、原料パルプとして未晒パルプ(漂白処理していないパルプ)を用いつつ従来の濃い茶色から薄い茶色の色目にする、すなわち白色度を適当値向上させて、需要者に与える安全性、清潔感のイメージを損なうことなく、視認性を向上させることが要求される。   However, as described above, the conventional paper towel made of NUKP has a very low whiteness. In paper towels used for various types of wiping, it is common to determine whether wiping has been performed or insufficient by visually checking the state of the object to be wiped attached to the surface of the paper towel, Higher whiteness is generally desirable for paper towels because higher whiteness is easier to check. However, consumers generally feel that brown paper towels are more natural than paper towels that are white enough to feel white, and prefer these products as unbleached paper towels. It is in. Therefore, while using unbleached pulp (raw pulp that has not been bleached) as the raw material pulp, the conventional dark brown to light brown color is changed, that is, the whiteness is increased to an appropriate value, giving the customer safety and cleanliness. It is required to improve the visibility without damaging the image.

そこで、本発明の主たる課題は、塩素などによる漂白処理を行っていない未晒パルプを原料とするペーパータオルにおける白色度の向上を図り、さらに柔らかさの向上をも図り、もって従来製品よりも白色度が高くかつやわらかい未晒パルプを原料とするペーパータオルを提供することにある。   Therefore, the main problem of the present invention is to improve the whiteness of paper towels made from unbleached pulp that has not been bleached with chlorine or the like, and to further improve the softness. The object is to provide a paper towel made from unbleached pulp which is high and soft.

漂白処理していない未晒パルプを原料とする家庭用薄葉紙により、天然素材である感じを呈しつつ白色度の向上を図られるペーパータオルを製造することができる。   By using household thin paper made from unbleached pulp that has not been bleached, it is possible to produce a paper towel that can improve whiteness while exhibiting the feeling of being a natural material.

また、LUKP(漂白処理していない広葉樹クラフトパルプ)はNUKP(漂白処理していない針葉樹クラフトパルプ)と比較して白色度低下の原因となるリグニンの含有量が低いため、これを含む原料パルプを抄紙してなるものとすれば、天然素材である感じを呈しつつ白色度を従来製品より向上することができる。   In addition, LUKP (unbleached hardwood kraft pulp) has a lower content of lignin that causes a decrease in whiteness than NUKP (unbleached softwood kraft pulp). If it is made from paper, the whiteness can be improved over the conventional product while presenting the feeling of being a natural material.

他方、JIS Z 8730で規定されるハンター色差式においてD=(L2+a2+b21/2におけるDの値が15以上、Lの値が10〜80、aの値が−10〜2、bの値が−10〜30であると従来製品より格段に白色度が高いものであり、拭取り時の確認性に優れる。 On the other hand, in the Hunter color difference formula defined by JIS Z 8730, the value of D at D = (L 2 + a 2 + b 2 ) 1/2 is 15 or more, the value of L is 10 to 80, and the value of a is −10 to 2 When the value of b is -10 to 30, the whiteness is remarkably higher than that of the conventional product, and the confirmation at the time of wiping is excellent.

他方、前記原料パルプ中にCTMP(ケミサーモメカニカルパルプ)を5〜50重量%含有せしめるとより柔らかいものとなる。   On the other hand, when 5 to 50% by weight of CTMP (chemothermomechanical pulp) is contained in the raw material pulp, it becomes softer.

JIS L 1096Eに基づくハンドルオメーター法によるソフトネスの値が3〜20gであるものは拭取りに好適な柔らかさ(拭取り操作をしやすくかつ柔らかな感じ)を示す。   Those having a softness value of 3 to 20 g by the handle ohm method based on JIS L 1096E exhibit softness suitable for wiping (easy to perform wiping operation and soft feeling).

紫外線吸収剤および酸化防止剤の少なくとも一方を、原料パルプに添加したのち抄紙してなるものとすると、耐候性に優れたものとなる。   When at least one of the ultraviolet absorber and the antioxidant is added to the raw material pulp and then paper is made, the weather resistance is excellent.

エンボスが付与されたものは、需要者に厚み感、ふんわり感を与える。また、原料パルプに対して柔軟剤を0.01〜1重量%添加すれば、より柔らかいものとなる。   Those with embossing give the consumer a sense of thickness and softness. Moreover, if a softening agent is added 0.01 to 1 weight% with respect to raw material pulp, it will become a softer thing.

また、本発明における家庭用薄葉紙の原料パルプはすべて未晒パルプである。   In addition, all the raw pulp of household thin paper in the present invention is unbleached pulp.

次いで、本発明の実施の形態を以下に詳述する。
本発明の家庭用薄葉紙は、漂白処理が施されていないパルプを原料とする。また、その原料パルプは、LUKPを含むものであり、LUKP以外のパルプも未晒パルプを用いる。LUKPは原料パルプ中に40重量%以上、特に好適には70重量%以上含む。LUKP以外の未晒パルプとしては、例えばNUKPなど漂白処理をしていない適宜のパルプを用いることができる。
Next, embodiments of the present invention will be described in detail below.
The thin paper for household use of the present invention is made from pulp that has not been bleached. Moreover, the raw material pulp contains LUKP, and unbleached pulp is also used for pulp other than LUKP. LUKP is contained in the raw pulp at 40% by weight or more, particularly preferably 70% by weight or more. As the unbleached pulp other than LUKP, for example, an appropriate pulp that has not been bleached, such as NUKP, can be used.

柔らかさおよび吸収性を発現させるためには、原料パルプ中にCTMPを15〜30重量%含有せしめる。CTMPは結束繊維が少ないためかかる範囲で含有せしめると、LUKP繊維と良好に絡み合い柔らかさが向上する。なお、CTMPによる柔らかさの発現は5重量%未満ではほとんどなく、また50重量%を越えるとペーパータオルとして使用するさいに好適なコシを担保するのが困難となる。ここで、CTMPは結束繊維が少ないことから叩解せずあるいは叩解度を低くして用いることができる。したがって、CTMPを原料パルプに配合するにあたっては、上記LUKPやNUKPなどの他の未晒パルプあるいはこれらの混合パルプの叩解処理を行ったのちに、CTMPを別叩解あるいは未叩解で混合して原料パルプとするのが好適である。このように配合すると、CTMPが不要に叩解されることがなく嵩だか感のあるペーパータオルにもなる。   In order to express softness and absorbability, the raw material pulp contains CTMP in an amount of 15 to 30% by weight. Since CTMP contains few binding fibers, if incorporated in such a range, it will be well entangled with LUKP fibers to improve softness. In addition, the expression of the softness by CTMP is hardly less than 5% by weight, and when it exceeds 50% by weight, it is difficult to secure a firmness suitable for use as a paper towel. Here, CTMP can be used without beating or having a low beating degree because it has few binding fibers. Therefore, when blending CTMP into the raw pulp, after the other unbleached pulp such as LUKP and NUKP or a mixed pulp thereof is beaten, the CTMP is mixed separately or unbeaten to obtain the raw pulp Is preferable. When blended in this way, CTMP is not beaten unnecessarily, and it becomes a paper towel with a feeling of bulk.

本発明のペーパータオルの抄紙方法は特に限定されないが、坪量10〜40g/m2程度に調整する。従来技術にしたがって、各種抄紙機を用いて抄紙することができる。なお、原料パルプのパルプ組成とペーパータオルのパルプ組成とはほぼ同様であり、ペーパータオル中のパルプ組成はJIS P 8120により測定することが可能である。 Papermaking process of paper towels of the present invention is not particularly limited, but adjusted to about basis weight of 10 to 40 g / m 2. Paper making can be performed using various paper machines according to the prior art. The pulp composition of the raw material pulp and the pulp composition of the paper towel are almost the same, and the pulp composition in the paper towel can be measured according to JIS P 8120.

また、本発明においては、原料パルプ中には適宜柔軟剤や界面活性剤を添加することができる。柔軟剤の例示としては、脂肪酸エステル系軟化剤(米国特許第3296065号明細書)、第4級アンモニウム塩型カチオン活性剤(特開昭48−22701号公報)、ウレタンアルコールもしくはその塩、またはカチオン化合物(特開昭60−139897号公報)、非陽イオン系界面活性剤(特開平2−99690号公報)、ポリシロキサン(特開平2−224626号公報、同3−900号公報)等がある。柔軟剤の添加量は、パルプ1トンあたり5.0kg以下とするのが望ましい。   In the present invention, a softener and a surfactant can be appropriately added to the raw material pulp. Examples of softeners include fatty acid ester softeners (US Pat. No. 3,296,065), quaternary ammonium salt type cationic activators (Japanese Patent Laid-Open No. 48-22701), urethane alcohols or salts thereof, or cations. Compounds (Japanese Patent Laid-Open No. 60-139897), non-cationic surfactants (Japanese Patent Laid-Open No. 2-99690), polysiloxanes (Japanese Patent Laid-Open Nos. 2-224626 and 3-900), and the like. . The addition amount of the softening agent is desirably 5.0 kg or less per ton of pulp.

本発明にかかるペーパータオルは、JIS Z 8730で規定されるハンター色差式においてD=(L2+a2+b21/2におけるDの値が15以上、Lの値が10〜80、aの値が−10〜2、bの値が−10〜30であるのが望ましい。かかる範囲であると、従来例と未晒パルプを原料とするペーパータオルと比較して観者が白いと感じるものであり、使用者が拭取りに使用したときに拭取り具合を視識しやすく、また、高級感もあるものとなる。ここで、Dの値が15未満であると白色度が低く拭取り時の視認性に劣るようになる。また、L値が10未満であるとくすんだ感じになり、80を越えるとあざやかさがあり天然素材感が得られなくなる。なお、ハンター色差式であらわされる上記各値は、従来既知の分光測色計等により測定することができる。 The paper towel according to the present invention has a D value of 15 or more, a value of L of 10 to 80, and a value of D = (L 2 + a 2 + b 2 ) 1/2 in the Hunter color difference formula defined in JIS Z 8730. Is preferably −10 to 2, and b is preferably −10 to 30. In such a range, the viewer feels white compared to the conventional example and a paper towel made from unbleached pulp, and when the user uses it for wiping, it is easy to see the wiping condition, In addition, there is a sense of quality. Here, when the value of D is less than 15, the degree of whiteness is low and the visibility at the time of wiping is inferior. Further, if the L value is less than 10, it becomes dull, and if it exceeds 80, there is vividness and a natural material feeling cannot be obtained. In addition, each said value represented by a Hunter color difference type | formula can be measured with a conventionally known spectrocolorimeter etc.

他方、本発明にかかるペーパータオルは、JIS L 1096Eに基づくハンドルオメーター法によるソフトネスの値が3〜20g、好ましくは4〜15g、特に好適には5〜10gであるのが望ましい。ソフトネスの値が3g未満であるとコシが発現しづらく拭取り性が悪化し、20gを越えると硬く拭取り性が悪化する。かかるソフトネスの調整は、上述の本発明にかかるLUKPの配合割合、CTMPの配合割合の範囲で各パルプの配合割合を適宜調整することおよび適宜の坪量の調整により達成することができる。   On the other hand, the paper towel according to the present invention desirably has a softness value of 3 to 20 g, preferably 4 to 15 g, particularly preferably 5 to 10 g according to a handle ohm method based on JIS L 1096E. If the softness value is less than 3 g, the wiping property is difficult to develop, and if it exceeds 20 g, the wiping property is hard and deteriorates. Such softness adjustment can be achieved by appropriately adjusting the blending ratio of each pulp within the range of the blending ratio of LUKP according to the present invention and the blending ratio of CTMP and adjusting the basis weight.

他方、本発明にかかるペーパータオルは、原料パルプ中に紫外線吸収剤および酸化防止剤の少なくとも一方を含有せしめる。添加量としては、1〜3重量%含有せしめる。本発明のペーパータオルは、従来例の未晒パルプを原料とするものと比較すれば格段に少ない量ではあるがリグニンが含まれている。リグニンは光酸化などの酸化により黄色あるいは茶色に変色するので、これが含まれていると経時的に白色度の後退が見られる。すなわち退色する。このような退色は製品の使用に影響がなくても需要者に対して品質低下したとの感じを与える。紫外線吸収剤あるいは酸化防止剤を適当量添加することにより、このようなリグニンの酸化による退色が防止され、従来にない白色度がより長期に渡って維持される。   On the other hand, the paper towel according to the present invention contains at least one of an ultraviolet absorber and an antioxidant in the raw material pulp. As addition amount, it is made to contain 1-3 weight%. The paper towel of the present invention contains lignin although it is a much smaller amount than that of a conventional example using unbleached pulp as a raw material. Lignin turns yellow or brown due to oxidation such as photo-oxidation, and if it is included, the whiteness is retreated over time. That is, it fades. Such discoloration gives the customer a feeling that the quality has deteriorated without affecting the use of the product. By adding an appropriate amount of an ultraviolet absorber or an antioxidant, such fading due to oxidation of lignin is prevented, and unprecedented whiteness is maintained for a longer period.

酸化防止剤としては熱や酸素による酸化を防止するフェノール系酸化防止剤、リン系酸化防止剤、硫黄系酸化防止剤と、HALS(Hindered Amine Light Stabilizer)と呼ばれるヒンダードアミン系光安定剤が挙げられる。   Examples of antioxidants include phenolic antioxidants that prevent oxidation due to heat and oxygen, phosphorus antioxidants, sulfur antioxidants, and hindered amine light stabilizers called HALS (Hindered Amine Light Stabilizer).

紫外線吸収剤としては、有機系、無機系のものが例示できる。有機系、無機系のものが例示できる。有機系のものとしては、サリチル酸系、ベンゾフェノン系、ベンゾトリチアゾール系、シアノアクリート系、公知のものが挙げられる。無機系の紫外線吸収剤としては酸化亜鉛、酸化セリウム、酸化チタン、酸化イットリウム等の遷移金属酸化物が適宜使用できる。   Examples of the ultraviolet absorber include organic and inorganic ones. Organic and inorganic materials can be exemplified. Examples of the organic type include salicylic acid type, benzophenone type, benzotrithiazole type, cyanoacrylate type, and known ones. As the inorganic ultraviolet absorber, transition metal oxides such as zinc oxide, cerium oxide, titanium oxide, yttrium oxide can be appropriately used.

また、本発明にかかるペーパータオルは、エンボス加工が付与されているものであると、使用者に厚み感を与えるものとなるとともに、拭取り性能が向上する。エンボス加工方法については特に限定されえず、従来既知のエンボス付与方法に従って適宜付与すればよい。例えば、湿紙あるいは乾紙に対してエンボスロールを押圧して付与する方法をとることができる。   Moreover, the paper towel concerning this invention will give a user a feeling of thickness, and the wiping performance improves that embossing is provided. The embossing method is not particularly limited, and may be appropriately applied according to a conventionally known embossing method. For example, the embossing roll can be pressed and applied to wet paper or dry paper.

他方、本発明にかかるペーパータオルの形状等については特に限定されるものではない、いわゆるロール巻きタイプであってもよいし、枚葉タイプであってもよい。また、1プライであってもよいし2プライ(二枚重ね)のものであってもよい。これらは、従来既知の技術にしたがって、適宜の形状にすればよい。   On the other hand, the shape of the paper towel according to the present invention is not particularly limited, and may be a so-called roll type or a single wafer type. Further, it may be one ply or two plies (double stack). These may be appropriately shaped according to a conventionally known technique.

また、本発明にかかるペーパータオルは、エンボス加工が施されていてもよい。エンボス加工を施すのであれば、製品の幅方向の20%の領域であって、かつ長手方向に連続的にまたは間欠的に施されているのが望ましい。なお、枚葉の製品の場合の幅方向とは製品時における短手方向であり、ロール製品の幅方向とは引き出し方向に対して直行する方向である。   Moreover, the paper towel concerning this invention may be embossed. If embossing is performed, it is desirable that the region is 20% in the width direction of the product and is continuously or intermittently applied in the longitudinal direction. In addition, the width direction in the case of a single wafer product is a short direction at the time of product, and the width direction of the roll product is a direction perpendicular to the drawing direction.

本発明にかかるペーパータオルは、漂白処理を行わない未晒パルプを原料とすることから排水中に漂白処理を含まない。
<試験例1>
Since the paper towel according to the present invention uses unbleached pulp that is not subjected to bleaching as a raw material, the wastewater does not include bleaching.

As a result, it is understood that the paper towel of Test Example 1 has no influence on the environment, has high whiteness, easily develops softness, and has improved weather resistance .
<Test Example 2>

CTMPの配合の仕方および割合等の効果について検討した。原料の配合割合および調整手順を変更して6種類の試料を作成し、各資料について物性等を測定した。試料1〜試料6の原料および調整手順は表2に示す。試料の調整については、表2中の手順の欄の(A)〜(G)の順に操作して調整した。なお、表中のヤング率は、SSTにより測定した超音波伝播速度より算出し、試料1を100として基準とした。   The effects of the method and proportion of CTMP were examined. Six types of samples were prepared by changing the mixing ratio of raw materials and the adjustment procedure, and the physical properties and the like of each material were measured. Table 2 shows the raw materials and preparation procedures of Sample 1 to Sample 6. About adjustment of the sample, it adjusted by operating in order of (A)-(G) of the column of the procedure in Table 2. The Young's modulus in the table was calculated from the ultrasonic propagation velocity measured by SST, and the sample 1 was taken as 100 as a reference.

試料1と試料2とを比較してみると、試料2のほうが比容積(嵩)が高い。すなわち、CTMを配合していない場合より、他のパルプとCTMP混合(CTMP配合割合15重量%)したのちに叩解したほうが嵩だかにできる。   When sample 1 and sample 2 are compared, sample 2 has a higher specific volume (bulk). That is, it is more bulky to beat after mixing with other pulp and CTMP (CTMP blending ratio of 15% by weight) than when CTM is not blended.

また、試料1〜試料3を比較すると、試料1→3の順に比容積(嵩)が高くなっている。すなわち、CTMPの配合割合を増加させると嵩だかなる。   Further, when Samples 1 to 3 are compared, the specific volume (bulk) increases in the order of Sample 1 → 3. That is, when the blending ratio of CTMP is increased, it becomes bulky.

さらに、試料2と試料5とを比較してみると、試料5のほうが比容積(嵩)が高い。他のパルプとともに叩解するよりも未叩解のほうが嵩だかとなる。   Furthermore, when the sample 2 and the sample 5 are compared, the sample 5 has a higher specific volume (bulk). Unbeaten is more bulky than beating with other pulp.

他方、紙力について、試料1〜3を比較してみると、CTMPの添加による紙力の低下はほとんど見られない、むしろ向上している。また、試料5は、試料1〜試料3と比較して紙力は若干低いが十分な数値である。CTMPを未叩解で配合しても紙力の低下がほとんどないことが解る。   On the other hand, when the samples 1 to 3 are compared with respect to the paper strength, a decrease in paper strength due to the addition of CTMP is hardly seen, but rather improved. Sample 5 has a slightly lower paper strength than Samples 1 to 3, but is a sufficient value. It can be seen that there is almost no decrease in paper strength even when CTMP is blended without beating.

他方、試料5と試料6とを比較すると試料5のほうが紙力が高い。すなわち、界面活性剤の添加については、CTMP添加後に添加したほうが好ましい。   On the other hand, when Sample 5 and Sample 6 are compared, Sample 5 has higher paper strength. That is, it is preferable to add the surfactant after adding CTMP.

以上のように、CTMPの配合割合および添加方法によって適宜、紙力、比容積など効果が相違することが確認できるが、試料1〜試料6のいずれもペーパータオル製品としては十分な性能である。なお、コスト面をも考慮すると未叩解でCTMPを添加する試料5が好適である。   As described above, it can be confirmed that the effects such as paper strength and specific volume are appropriately different depending on the blending ratio and addition method of CTMP. However, all of Sample 1 to Sample 6 have sufficient performance as a paper towel product. In view of cost, the sample 5 to which CTMP is added without being beaten is preferable.

本発明は、家庭用薄葉紙、特にキッチンペーパー、クッキングペーパーなどの、各種拭取りの用途等に用いられるペーパータオルに利用することができる。   INDUSTRIAL APPLICABILITY The present invention can be used for paper towels used for various wiping applications such as household thin paper, particularly kitchen paper and cooking paper.
