Abstract
Description
本発明は、使用に際して、ロール状体を横方向に沿って引き裂いて所要面積のシートとして使用するロール状ペーパー及びロール状紙製品に関するものである。 The present invention relates to a roll-shaped paper and a roll-shaped paper product that are used as a sheet having a required area by tearing a roll-shaped body along a transverse direction in use.
家庭用として使用可能ではあるものの、業務用において、鮮度を保持するために肉や魚を包むあるいは肉や魚から出る体液いわゆるドリップを吸収するために、「食材紙」と呼ばれる分野のロール状ペーパーが知られ、ほんの一部のメーカーによって市販されており、使用に際して、ミシン目がなくとも、あるいはハサミやカッターを使わなくても横方向に沿ってほぼ直線状に綺麗に引き裂くことが要求されている。
この種の食材紙においては、たとえばドリップを速やかにかつ余裕のある吸収量をもった吸収特性を示す必要があるほか、主に肉や魚を対象とするために、ドリップによる食材紙の破れなどを防止する観点から、湿潤強度が高いことが要求される。
ところが、吸収特性を向上させるために、嵩高にすることが考えられるが、これを追求すると湿潤強度が低くなる傾向にあることから、吸収特性と高い湿潤強度とは相反するものであり、その改良が望まれている。しかも、その相反に加えて、前述のように、横方向に沿ってほぼ直線状に綺麗に引き裂くことが要求されることが解決手段をより一層難しくしている。
In this type of food paper, for example, the drip needs to show absorption characteristics with a quick and generous amount of absorption, and in order to mainly target meat and fish, torn food paper due to drip, etc. From the viewpoint of preventing water, high wet strength is required.
However, in order to improve the absorption characteristics, it can be considered to be bulky, but if pursuing this, the wet strength tends to be low, so the absorption characteristics and high wet strength are contradictory, and the improvement Is desired. Moreover, in addition to the contradiction, as described above, it is further difficult to solve the problem that it is required to tear in a substantially straight line along the lateral direction.
そこで、本発明の主たる課題は、使用に際して、ミシン目がなくとも、あるいはハサミやカッターを使わなくても横方向に沿ってほぼ直線状に綺麗に引き裂くことが可能なロール状ペーパー及びロール状紙製品を提供することにある。他の課題は、吸収特性に優れると共に高い湿潤強度を示すものを提供することにある。 Therefore, the main problem of the present invention is that roll paper and roll paper that can be torn cleanly in a substantially straight line along the lateral direction without using perforations or without using scissors or a cutter. To provide products. Another object is to provide a material having excellent absorption characteristics and high wet strength.
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＞
米坪が２０〜６５ｇ／ｍ2、乾燥引張強度（ＪＩＳ Ｐ ８１１３に規定される）の縦横比が１．０〜１．５、ＪＩＳ Ｐ ８１１６に従う横方向の引裂強度が９０ｇｆ以下であり、
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が０．３〜０．４５重量％含有され、ウエットクレープが施されていることを特徴とするロール状ペーパー。
The present invention that has solved the above problems is as follows.
<Invention of Claim 1>
US basis weight is 20 to 65 g / m 2 , dry tensile strength (as defined in JIS P 8113) aspect ratio is 1.0 to 1.5, transverse tear strength according to JIS P 8116 is 90 gf or less,
A roll paper characterized by containing 0.3 to 0.45% by weight of a polyacrylamide / epichlorohydrin resin with respect to a pulp raw material and subjected to a wet crepe.
（作用効果）
本発明は、乾燥引張強度の縦横比（縦方向／横方向）を１．０〜１．５とし、縦裂けの発生を低減して、より直線状に近い引き裂きを可能とした。また、（横方向）引裂強度を９０ｇｆ以下として低いものとした。さらに、所要の吸収量を確保するために、米坪を２０〜６５ｇ／ｍ2とした。
他方、前述のように食材、特に肉や魚を対象とするためには、ドリップによる破れなどを防止する観点から、湿潤強度が高いことが要求される。そこで、湿潤紙力増強剤を添加して湿潤強度を高めることが考えられるが、従来は湿潤紙力増強剤の添加によって、特に吸収速度が低下し、パルプ繊維間に十分に浸透せず、ドリップの吸収量が低いことが知見された。
これに対し、本発明に従って、ウエットクレープを施すことにより、ペーパーを嵩高にしてドリップの吸収速度及び吸収量を高めて吸収特性を向上させた結果、湿潤紙力増強剤の添加量を増やしても、吸収特性の低下がないまたは少ないことにより、湿潤強度を高めることができることを知見し、前述の相反する特性の両者を一挙に改善したものである。さらに、ウエットクレープ処理は、横方向の引裂特性にも少なからず影響し、本発明の利点を顕在化させている。なお、特許文献５のシート及び従来の食材紙はドライクレープ加工によるものである。
(Function and effect)
In the present invention, the aspect ratio (longitudinal direction / lateral direction) of the dry tensile strength is set to 1.0 to 1.5, the occurrence of longitudinal tearing is reduced, and tearing closer to a straight line is enabled. Further, the tear strength (lateral direction) was set to 90 gf or less to be low. Furthermore, in order to ensure a required amount of absorption, the rice tsubo was set to 20 to 65 g / m 2 .
On the other hand, in order to target foodstuffs, particularly meat and fish as described above, high wet strength is required from the viewpoint of preventing tearing due to drip. Therefore, it is conceivable to increase the wet strength by adding a wet paper strength enhancer. Conventionally, however, the addition of the wet paper strength enhancer decreases the absorption rate in particular and does not sufficiently penetrate between pulp fibers. It has been found that the absorption amount of is low.
On the other hand, as a result of applying wet crepe according to the present invention and increasing the drip absorption rate and absorption amount by increasing the bulk of the paper and improving the absorption characteristics, the addition amount of the wet paper strength enhancer can be increased. It has been found that the wet strength can be increased by having no or little decrease in absorption characteristics, and both of the above-mentioned conflicting characteristics are improved at once. Furthermore, the wet creping process has a considerable influence on the tearing properties in the lateral direction, revealing the advantages of the present invention. In addition, the sheet | seat of patent document 5 and the conventional foodstuff paper are based on dry crepe processing.
＜請求項２記載の発明＞
密度が０．２１ｇ／ｃｍ3以下、湿潤引張強度（横）が１０００〜１４００ＣＮ、吸水量が２００ｇ／ｍ2以上である請求項１記載のロール状ペーパー。
<Invention of Claim 2>
The roll paper according to claim 1, wherein the density is 0.21 g / cm 3 or less, the wet tensile strength (horizontal) is 1000 to 1400 CN, and the water absorption is 200 g / m 2 or more.
（作用効果）
密度が低く嵩高であるために、ウエットクレープ処理との相乗で吸収量が高いものとなり、しかも、必要な湿潤引張強度（横）の値を得ることができる。
(Function and effect)
Since the density is low and the bulk is high, the amount of absorption is high in synergy with the wet creping treatment, and the necessary wet tensile strength (lateral) value can be obtained.

ロール状ペーパーが横方向に沿って引き裂いて使用するロール状製品とされている請求項１または２項に記載のロール状紙製品。
<Invention of Claim 3>

（作用効果）
本発明の効果は、ロール状製品である場合に顕在化する。
(Function and effect)
The effect of the present invention becomes apparent when the product is a roll product.
以上のとおり本発明によれば、使用に際して、ミシン目がなくとも、あるいはハサミやカッターを使わなくても横方向に沿ってほぼ直線状に綺麗に引き裂くことが可能なロール状ペーパー及びロール状紙製品となる。また、吸収特性に優れると共に高い湿潤強度を示すものとなる。 As described above, according to the present invention, roll paper and roll paper that can be torn cleanly in a substantially straight line along the horizontal direction without using perforations or without using scissors or a cutter. Become a product. In addition, it has excellent absorption characteristics and high wet strength.
以下、本発明の一実施形態について詳説する。
本発明のロール状ペーパーは、パルプ繊維を紙料として製造することができる。パルプ繊維としては限定されないが、ＬＢＫＰやＮＢＫＰなどを使用できる。
本発明は、坪量が２０〜６５ｇ／ｍ2のロール状ペーパー全般を対象とするが、坪量が３０〜６０ｇ／ｍ2の厚手のものが好ましく、特に坪量が３５〜５０ｇ／ｍ2のものが好ましい。
Hereinafter, an embodiment of the present invention will be described in detail.
The roll paper of the present invention can be produced using pulp fiber as a stock. Although it does not limit as a pulp fiber, LBKP, NBKP, etc. can be used.
The present invention has a basis weight to target roll-shaped paper general 20~65g / m 2, preferably has a basis weight of thick 30 to 60 g / m 2, in particular basis weight 35~50g / m 2 Are preferred.
本発明のロール状ペーパーでは、ＪＩＳ Ｐ ８１１３に規定される乾燥引張強度の縦横比が１．０〜１．５とされる。この縦横比は、ワイヤーパートにおけるジェットワイヤー比等、各種抄造条件の変更により調整できる他、特に吸引脱水式円網抄紙機を用いる場合における抄造条件の調整によって達成できる。たとえば、特許文献５に記載の抄造条件を採用できる。乾燥引張強度の縦横比（縦方向／横方向）を低く抑えることで、縦裂けの発生が低減し、より直線状に近い引裂が可能となる。
また、本発明のロール状ペーパーでは、ＪＩＳ Ｐ ８１１３に規定される引張破断伸び（縦方向）が１５〜２５％とすることができる。引張破断伸びは、クレープ加工の程度（所謂クレープ率）により調整することができる。引張破断伸びを低く抑えることにより、紙に加わる引裂力の方向が紙の伸びにより不規則に変化するのを防止し、縦や斜め方向への裂けの発生を低減することができる。しかるに、この伸びの値は、特許文献５のものが教示する値より大きい。これは、先にも触れたように吸収特性を高めるために大きくし、その反対に主に抄造条件の変更により引き裂き性を良好にしたものである。
より好ましい形態では、本発明のロール状ペーパーは、ＪＩＳ Ｐ ８１１６に規定される横方向の引裂強度が９０ｇｆ以下、特に８５ｇｆ以下とされる。また、引裂センターからのずれが２０ｍｍ下であることが好ましい。なお、引裂センターからのずれは、ＪＩＳ Ｐ ８１１６で規定される引裂強度測定時に、引裂始めの部分から引裂く方向と逆方向に引裂いた切れ目が何ｍｍずれたかで測定する。横方向の引裂強度は、パルプの配合、叩解度（フリーネス）、引張破断伸び等を変更することにより調整できる。横方向の引裂強度が９０ｇｆ以下であると、引裂きに要する力が適切となるだけでなく、不要な力が不要な方向に作用し難くなり、より綺麗に引裂くことができるようになる。逆に、９０ｇｆを越えると、引裂きに要する力が過度となるばかりか、引裂きの方向性において抑止し難いものとなる。
In the rolled paper of the present invention, the aspect ratio of the dry tensile strength defined in JIS P 8113 is 1.0 to 1.5. This aspect ratio can be adjusted by changing various papermaking conditions such as the jet wire ratio in the wire part, and can be achieved by adjusting the papermaking conditions especially when using a suction dewatering type circular net paper machine. For example, the papermaking conditions described in Patent Document 5 can be adopted. By keeping the aspect ratio (longitudinal / lateral) of the dry tensile strength low, the occurrence of longitudinal tearing is reduced and tearing closer to a straight line becomes possible.
Moreover, in the roll-shaped paper of this invention, the tensile breaking elongation (longitudinal direction) prescribed | regulated to JISP8113 can be 15-25%. The tensile elongation at break can be adjusted by the degree of creping (so-called crepe rate). By keeping the tensile elongation at break low, it is possible to prevent the direction of the tearing force applied to the paper from changing irregularly due to the elongation of the paper, and to reduce the occurrence of tearing in the longitudinal and oblique directions. However, the value of this elongation is larger than the value taught by Patent Document 5. As mentioned above, this is increased to enhance the absorption characteristics, and conversely, the tearability is improved mainly by changing the papermaking conditions.
In a more preferred form, the roll-shaped paper of the present invention has a transverse tear strength specified in JIS P 8116 of 90 gf or less, particularly 85 gf or less. Moreover, it is preferable that the deviation from the tear center is 20 mm below. Note that the deviation from the tear center is measured by how many mm the break of the tear in the direction opposite to the tearing direction has shifted from the tear starting portion when measuring the tear strength defined in JIS P8116. The tear strength in the transverse direction can be adjusted by changing the blending of pulp, the degree of beating (freeness), the tensile elongation at break, and the like. When the tear strength in the lateral direction is 90 gf or less, not only the force required for tearing is appropriate, but also an unnecessary force is less likely to act in an unnecessary direction, and tearing can be performed more neatly. On the other hand, if it exceeds 90 gf, not only will the force required for tearing be excessive, but it will be difficult to inhibit the direction of tearing.
本発明のロール状ペーパーは、図１に示すように、ロール状ペーパーＳをロール状にしてなり、横方向に沿って引き裂いて使用するロール状製品Ｒ、特にロール状のペーパー（たとえば食材紙）に好適である。このような製品では複数枚のロール状ペーパーを重ねて１シートとして使用する形態があるが、このような形態では本明細書で述べる乾燥・湿潤引張強度、引張破断伸び、引裂強度等の試験値は複数枚重ねたシート状態における値を意味するものである。
本発明は、ロール状ペーパーに限定されるものではないが、例えば３５〜５０ｇ／ｍ2程度のロール状ペーパーとする場合、湿潤引張強度（ＪＩＳ Ｐ ８１３５）は横方向が１０００〜１４００ＣＮ、吸水量は２００ｇ／ｍ2以上であるのが好ましく、乾燥引張強度（ＪＩＳ Ｐ ８１１３）は上記本発明の縦横比を満たす範囲内で、横方向が２１００〜２８００ＣＮであるのが好ましい。
なお、吸水量とは次の方法で測定されるものである。１００ｍｍ×１００ｍｍの試験片を、針金でできた縦横２０ｍｍ間隔でできた網の上に載せたまま水に浸し、シート片全体が浸った後、垂直に網を持ち上げ、そこから３０秒間自然に水を切った後のシート重量から水に浸す前のシート重量を差し引いて、吸収した水を算出し、ｇ／ｍ2の単位であらわす。
As shown in FIG. 1, the roll-shaped paper of the present invention is obtained by forming a roll-shaped paper S into a roll shape, and tearing the roll-shaped paper R along the horizontal direction, particularly a roll-shaped paper (for example, food paper). It is suitable for. In such a product, there is a form in which a plurality of roll papers are stacked and used as one sheet. In such a form, test values such as dry / wet tensile strength, tensile break elongation, and tear strength described in this specification are used. Means a value in a state where a plurality of sheets are stacked.
Although this invention is not limited to roll-shaped paper, for example, when setting it as roll-shaped paper of about 35-50 g / m < 2 >, the horizontal direction is 1000-1400CN, and water absorption is wet tensile strength (JIS P 8135). Is preferably 200 g / m 2 or more, and the dry tensile strength (JIS P 8113) is preferably 2100 to 2800 CN in the lateral direction within the range satisfying the aspect ratio of the present invention.
The water absorption is measured by the following method. A test piece of 100 mm × 100 mm is immersed in water while being placed on a mesh made of wire at intervals of 20 mm in length and breadth. After the entire sheet piece is soaked, the net is lifted vertically, and then the water is naturally left for 30 seconds. Subtract the sheet weight before soaking in water from the sheet weight after cutting the water to calculate the absorbed water and express it in units of g / m 2 .
他方、本発明では、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が０．３〜０．４５重量％含有され、ウエットクレープが施されているものである。
ポリアクリルアミド・エピクロルヒドリン樹脂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の低下となる。
また、本発明では、従来品のようにドライクレープでなく、ウエットクレープ処理のよって得る。クレープ率としては、１０〜２０％が望ましい。さらに望ましくは１４〜１７％がよい。１０％未満であると、シート表面がほぼ平滑になるため、表面積が小さくなり、吸水特性が小さくなる。逆に、２０％を越えると、嵩高になるため、吸水特性は向上するものの、使用に際して引裂くとき、引裂きに要する力が横方向へは伝わる一方で、紙厚方向全体に均一に伝わりにくく、引裂いた切り口が、紙厚方向で部分的に層状に剥離したようになる恐れがある。
On the other hand, in this invention, 0.3-0.45 weight% of polyacrylamide and epichlorohydrin resin are contained with respect to a pulp raw material, and the wet crepe is given.
When the amount of the polyacrylamide / epichlorohydrin resin is small, the wet strength is insufficient. On the other hand, when the amount is excessively added, the water absorption property is deteriorated.
In the present invention, it is obtained not by dry crepe as in the conventional product but by wet crepe treatment. As a crepe rate, 10 to 20% is desirable. 14 to 17% is more desirable. If it is less than 10%, the surface of the sheet becomes almost smooth, so that the surface area becomes small and the water absorption property becomes small. On the other hand, if it exceeds 20%, the water absorption property is improved because it becomes bulky, but when tearing in use, the force required for tearing is transmitted in the lateral direction, but it is difficult to transmit uniformly throughout the paper thickness direction. There is a possibility that the torn cut surface may be partially peeled off in the paper thickness direction.
以下に、実施例を示して本発明の効果を明らかにする。
（実験１）
特許文献５の図２に示すフォーマーを用い、広葉樹パルプを９５重量％、針葉樹パルプ５％のパルプを使用し、ジェットワイヤー比、フリーネスなどの抄造条件を変化させながら、抄紙を行うとともに、ウエットクレープ処理を行い、幅６００ｍｍ、長さ１００ｍのロール状ペーパーを得た。
また、湿潤紙力増強剤の種類及び添加量を変化させ、市販品との比較も行った。
また、表１に示すように、各種の製造条件で各種試験性能を有するロール状ペーパーについて、横方向に引裂いた。そして引裂き特性を、◎…非常に良い、○…良い、×…悪い、の三段階で評価した。また引裂いた縁を観察し、縁の乱れ具合を「特に綺麗」、「綺麗」、「若干乱れる」、「乱れ大」の四段階で評価した。評価結果は表１に示されるとおりであり、本発明に係る実施例１〜５は、比較例１〜６と比べて著しく綺麗に引裂くことが可能であった。また、高い吸水量と高い湿潤引張強度を示すものであることが判った。
Hereinafter, the effects of the present invention will be clarified by showing examples.
(Experiment 1)
Using the former shown in FIG. 2 of Patent Document 5, using hardwood pulp of 95% by weight and softwood pulp of 5%, paper making while changing paper making conditions such as jet wire ratio and freeness, and wet crepe Processing was performed to obtain a roll paper having a width of 600 mm and a length of 100 m.
Moreover, the kind and addition amount of a wet paper strength enhancer were changed, and the comparison with a commercial item was also performed.
Moreover, as shown in Table 1, the roll paper having various test performances under various production conditions was torn in the lateral direction. The tear characteristics were evaluated in three stages: ◎ ... very good, ◯ ... good, × ... bad. In addition, the torn edges were observed, and the edge disorder was evaluated in four stages: “particularly beautiful”, “beautiful”, “slightly disturbed”, and “largely disturbed”. The evaluation results are as shown in Table 1, and Examples 1 to 5 according to the present invention were able to be remarkably torn compared with Comparative Examples 1 to 6. Moreover, it turned out that a high water absorption and a high wet tensile strength are shown.
