Description
本発明は、紙製ワイパー（払拭用紙）に関するものである。 The present invention relates to a paper wiper (wiping paper).
研究施設や検査施設、病院等では、試験管やピペット等の試験器具に付着した水滴や検査薬等、微細な汚れの拭き取りのために不織布製のワイパー（例えば特許文献１参照）が汎用されている。ワイパーにおいては、拭き取り性能はもちろんのこと、拭き取り面に紙粉を残さないように極めて低い発塵性が要求される。
しかしながら、従来のワイパーでは、掻き取り性能や低発塵性を重視するあまり、硬すぎて、細かな部分や小さな凹凸を有する部分の拭き取りが困難であった。
However, conventional wipers are too hard to place importance on scraping performance and low dust generation, and it is difficult to wipe fine portions and portions having small irregularities.
そこで、本発明の主たる課題は、掻き取り性能や低発塵性を損ねずに、柔軟性を向上したワイパーを提供することにある。 Then, the main subject of this invention is providing the wiper which improved the softness | flexibility, without impairing scraping performance and low dust generation property.
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＞
ドライクレープ加工によりクレープを施したなる米坪２０〜４０ｇ／ｍ2の紙製ワイパーであって、
抄紙に際して、ＮＢＫＰを７０〜１００重量％、ＬＢＫＰを０〜３０重量％配合したパルプ原料を用いるとともに、パルプスラリーのフリーネスを叩解により２０〜１００ｃｃ低下させ、かつ、
前記ドライクレープ加工に際し、クレープ率を２０〜４０％とし、クレーピングドクターとドライヤとの接触角を１１５〜１３０度とした、
ことを特徴とする紙製ワイパー。
The present invention that has solved the above problems is as follows.
<Invention of Claim 1>
A paper wiper having a basis weight of 20 to 40 g / m 2 creped by dry creping,
In making paper, while using a pulp raw material containing 70 to 100% by weight of NBKP and 0 to 30% by weight of LBKP, the freeness of the pulp slurry is reduced by 20 to 100 cc by beating, and
In the dry creping process, the crepe rate was 20 to 40%, and the contact angle between the creping doctor and the dryer was 115 to 130 degrees.
Paper wiper characterized by that.
（作用効果）
本発明では、低米坪のクレープ紙からなる紙製ワイパーとすることにより、汚れ掻き取り性および柔軟性に優れるものとなっている。しかし、それだけでは、紙粉が発生し易くなってしまう。そこで、本発明では、原料パルプのＮＢＫＰを高配合にするとともに、パルプスラリーのフリーネスを叩解により２０〜１００ｃｃ低下させることによって、柔軟性を損ねずに紙粉の発生を抑制したものである。
なお、フリーネスとはカナダ標準ろ水度（ＪＩＳ Ｐ ８１２１）を意味し、フリーネスを低下させるとは、未叩解時のフリーネスを基準として定まるものであり、その低下幅はフリーネスダウン幅ともいわれているものである。
他方、クレープを施すことにより汚れ掻き取り性が向上する。しかし、本発明では柔軟性が向上するため（特に柔軟剤を用いた場合はなおさらである）、通常用いられているクレープ加工ではクレープが細かくなり、掻き取り性が低下する。また、紙粉が発生し易くなるおそれもある。そこで、本項記載のように、クレープ率を２０〜４０％とし、クレーピングドクターの接触角を１１５〜１４０度とすることで、粗いクレープを施す。この場合、クレープ加工に起因する紙粉の発生も極めて少なくなる利点がある。
(Function and effect)
In the present invention, by using a paper wiper made of crepe paper having a low surface area, the soil scraping property and flexibility are excellent. However, paper dust is likely to be generated by itself. Therefore, in the present invention, the NBKP of the raw material pulp is highly blended and the freeness of the pulp slurry is reduced by 20 to 100 cc by beating, thereby suppressing the occurrence of paper dust without impairing flexibility.
Freeness means Canadian standard freeness (JIS P 8121). Decreasing freeness is determined on the basis of the freeness when unbeaten, and the decrease is also called the freeness down range. Is.
On the other hand, the soil scraping property is improved by applying the crepe. However, since the flexibility is improved in the present invention (particularly when a softening agent is used), the crepe becomes fine in the usual creping process, and the scraping property is lowered. Moreover, there is a possibility that paper dust is likely to be generated. Therefore, as described in this section, a rough crepe is applied by setting the crepe rate to 20 to 40% and the contact angle of the creping doctor to 115 to 140 degrees. In this case, there is an advantage that generation of paper powder due to creping is extremely reduced.
＜請求項２記載の発明＞
前記パルプスラリーに柔軟剤を対パルプ重量比で０．０５〜０．２％添加してなる、請求項１記載の紙製ワイパー。
<Invention of Claim 2>
The paper wiper according to claim 1, wherein 0.05 to 0.2% of a softener is added to the pulp slurry in a weight ratio to the pulp.
（作用効果）
本発明では、単にＮＢＫＰを高配合とするだけでなく、フリーネスを低下させる。よって、単に低米坪とした場合と比べると柔軟性は低くならざるを得ない。よって、柔軟性を向上させるために、本項記載のように柔軟剤を添加するのは好ましく、特に本項記載の量で添加すると、柔軟性だけでなく、吸水性も向上するため好ましい。
(Function and effect)
In the present invention, not only high NBKP content but also freeness is reduced. Therefore, the flexibility is inevitably low compared to the case where the area is simply low. Therefore, in order to improve flexibility, it is preferable to add a softening agent as described in this section, and it is particularly preferable to add it in the amount described in this section because not only flexibility but also water absorption is improved.
以上のとおり、本発明によれば、掻き取り性能や低発塵性を損ねずに、柔軟性を向上できる等の利点がもたらされる。 As described above, according to the present invention, there is an advantage that flexibility can be improved without impairing scraping performance and low dust generation.
以下、本発明の一実施形態について詳説する。
本発明の紙製ワイパーは、原料パルプとしてＮＢＫＰ（針葉樹晒クラフトパルプ）を７０〜１００重量％配合する。必要に応じて、ＬＢＫＰ（広葉樹晒クラフトパルプ）を３０重量％まで配合することができる。ＮＢＫＰが７０重量％未満では紙粉発生量が多く、精度が要求される用途には不向きとなる。より好ましいＮＢＫＰの配合量は８０重量％以上である。
Hereinafter, an embodiment of the present invention will be described in detail.
The paper wiper of the present invention contains 70 to 100% by weight of NBKP (conifer bleached kraft pulp) as a raw material pulp. If necessary, LBKP (hardwood bleached kraft pulp) can be blended up to 30% by weight. If NBKP is less than 70% by weight, a large amount of paper dust is generated, which is unsuitable for applications that require accuracy. A more preferable amount of NBKP is 80% by weight or more.
本発明では、抄紙に際して叩解を行い、パルプスラリーのフリーネスを未叩解時よりも２０〜１００ｃｃ低下させる。フリーネスの低下が２０ｃｃ未満であると、繊維間の絡み合いが少ないため紙粉が発生し易くなり、１００ｃｃを超えると、繊維間隙が小さく、緻密な構造になるため硬くなるととともに吸水性に劣るようになる。より好ましいフリーネスの低下幅は４０〜１００ｃｃである。 In the present invention, beating is performed at the time of papermaking, and the freeness of the pulp slurry is reduced by 20 to 100 cc compared to when unbeaten. If the decrease in freeness is less than 20 cc, paper entanglement is less likely to occur because of less entanglement between the fibers. Become. A more preferable reduction in freeness is 40 to 100 cc.
柔軟性および吸水性を向上させるために、パルプスラリーには、柔軟剤を対パルプ重量比で０．０５〜０．２％添加するのが好ましい。添加量が０．０５重量％未満では効果が殆ど発現せず、０．２％を超えると効果が飽和し、費用対効果が低下する。柔軟剤としては、脂肪酸エステル系柔軟剤、ポリリン酸塩柔軟剤、ポリシロキサン、第４級アンモニウム塩型カチオン系界面活性剤等を用いることができるが、特に脂肪酸エステル系柔軟剤を用いることが望ましい。 In order to improve flexibility and water absorption, it is preferable to add a softening agent to the pulp slurry in an amount of 0.05 to 0.2% by weight of the pulp. If the addition amount is less than 0.05% by weight, the effect is hardly exhibited, and if it exceeds 0.2%, the effect is saturated and the cost effectiveness is reduced. As the softener, fatty acid ester softeners, polyphosphate softeners, polysiloxanes, quaternary ammonium salt cationic surfactants and the like can be used, but it is particularly desirable to use fatty acid ester softeners. .
本発明では、抄紙に際してドライクレープ加工によりクレープを施す。クレープは特に限定されるものではないが、クレープ率（＝（ドライヤ周速−リール周速）÷ドライヤ周速×１００）を２０〜４０％とし、クレーピングドクターの接触角を１１５〜１３０度とすると、嵩高で目が粗く、掻き取り性に優れるクレープとなるため好ましい。クレーピングドクターの接触角が１１５度未満では掻き取り性に劣るクレープ形状となり、１３０度を超えるとドライヤから紙を剥ぎ取ることができない。 In the present invention, creping is performed by dry creping during paper making. The crepe is not particularly limited, but the crepe rate (= (dryer peripheral speed−reel peripheral speed) ÷ dryer peripheral speed × 100) is 20 to 40%, and the contact angle of the creping doctor is 115 to 130 degrees. Then, since it becomes a crepe which is bulky and coarse, and is excellent in scraping property, it is preferable. If the contact angle of the creping doctor is less than 115 degrees, the crepe shape is inferior in scraping property, and if it exceeds 130 degrees, the paper cannot be peeled off from the dryer.
本発明の紙製ワイパーでは、米坪が２５〜４０ｇ／ｍ2とされる。米坪が２５ｇ／ｍ2未満では紙粉が発生し易くなるとともに、厚み不足、強度不足によりワイパーとして用いることが困難になる。また、米坪が４０ｇ／ｍ2を超えると硬くなり過ぎ、細かな部分や小さな凹凸を有する部分の拭き取りが困難となる。
また、本発明の紙製ワイパーでは、必要に応じて紙力増強剤（内添・外添）等、公知の添加剤を用いることもできる。
なお、本発明の紙製ワイパーの抄紙方法自体は、上述した特定の条件の組み合わせを除けば、基本的に公知の方法を採用することができる。
In the paper wiper of the present invention, the rice basis weight is 25 to 40 g / m 2 . When the basis weight is less than 25 g / m 2 , paper powder is likely to be generated, and it becomes difficult to use as a wiper due to insufficient thickness and insufficient strength. On the other hand, when the rice tsubo exceeds 40 g / m 2 , it becomes too hard and it becomes difficult to wipe fine portions or portions having small irregularities.
In the paper wiper of the present invention, known additives such as a paper strength enhancer (internal addition / external addition) may be used as necessary.
In addition, the paper making method itself of the paper wiper of the present invention can basically adopt a known method except for the combination of the specific conditions described above.
表１及び表２に示す各種の紙製ワイパーを製造し、紙粉の発生量、掻き取り性、柔軟性、吸水性について評価した。
なお、柔軟剤としては、脂肪酸エステル系柔軟剤を使用した。
また、紙粉の発生量についは、１０秒間手で揉んだ時に発生する５０μｍ以上の紙粉の個数を測定し、紙粉が５０個以下（とても少ない）を「◎」、５１〜１００個（少ない）を「○」、１００個以上（多い）を「×」として評価した。
また、掻き取り性については、試験管に一定レベルの汚れを付着させ、この汚れを実際に拭き取り、掻き取り性がとてもよいを「◎」、掻き取り性がよいを「○」、掻き取り性が悪いを「×」として評価した。
さらに、柔軟性については、手で揉んだ時の感触を調べ、柔軟性がとてもよいを「◎」、柔軟性がよいを「○」、柔軟性が悪いを「×」として評価した。
さらに、吸水性については、試験管に一定レベルの水滴を付着させ、この水滴を一回拭き取った後の水滴の残り具合を目視確認し、吸水性がとてもよいを「◎」、吸水性がよいを「○」、吸水性が悪いを「×」として評価した。
Various paper wipers shown in Table 1 and Table 2 were produced, and the amount of paper dust generated, scraping property, flexibility, and water absorption were evaluated.
As the softener, a fatty acid ester softener was used.
Regarding the amount of paper dust generated, the number of paper dust of 50 μm or more that is generated when it is rubbed by hand for 10 seconds is measured, and 50 or less (very little) paper dust is expressed as “◎”, 51 to 100 ( “Low” was evaluated as “◯”, and 100 or more (large) was evaluated as “×”.
As for scraping property, a certain level of dirt is attached to the test tube, and the dirt is actually wiped off. “◎” indicates that the scraping property is very good, “○” indicates that the scraping property is good, and scraping property. Was evaluated as “x”.
Furthermore, regarding the flexibility, the feeling when squeezed by hand was examined, and “◎” was evaluated as being very flexible, “◯” was evaluated as being very flexible, and “X” was evaluated as being poor.
Furthermore, for water absorption, a certain level of water droplets was attached to the test tube, and the remaining water droplets were visually checked after wiping the water droplets once. Was evaluated as “◯”, and poor water absorption was evaluated as “x”.
本発明の紙製ワイパーは、研究施設や検査施設、病院等において、試験管やピペット等の試験器具に付着した水滴や検査薬等、微細な汚れの拭き取り等に利用できるものである。 The paper wiper of the present invention can be used for wiping off fine dirt such as water droplets and test agents attached to test instruments such as test tubes and pipettes in research facilities, inspection facilities, hospitals and the like.
