Abstract
Description
本発明は、茶殻やコーヒー粕などの飲料残渣粉砕物を配合した印刷用紙に関する。 The present invention relates to a printing paper blended with a crushed beverage residue such as tea husk and coffee cake.
従来、茶葉や茶殻などを紙に配合し、模様紙にすることや脱臭紙にすることが行われている。これらの一例としては、パルプスラリー中に、紅茶、緑茶、ウーロン茶などの茶葉もしくは茶粕を添加した模様紙（下記特許文献１参照）、緑茶製造工程の揉機による揉み工程において発生し上記揉機に付着した皮状物質を用い、これをパルプ原料に配合した脱臭紙（下記特許文献２参照）、紙繊維に茶葉を含有させた脱臭・芳香機能を有する紙シート（下記特許文献３参照）、茶殻と繊維状パルプとを絡み合わせて抄紙し、抗菌機能を有する茶殻配合紙（下記特許文献４参照）などがある。 Conventionally, tea leaves or tea husks are blended into paper to make patterned paper or deodorized paper. As an example of these, pattern paper (see Patent Document 1 below) in which tea leaves or teacups such as black tea, green tea, oolong tea, etc. are added to pulp slurry. A deodorized paper (see Patent Document 2 below), a paper sheet containing tea leaves in paper fibers (see Patent Document 3 below), a tea shell, There is a tea-shell blended paper (see Patent Document 4 below) having an antibacterial function by making paper by entwining with fibrous pulp.
しかし、上記のような茶葉や茶殻を配合した紙は、紙の表面上に茶葉あるいは茶殻が露出しているため、耐光性が劣り、長期間光にあてると茶葉あるいは茶殻が変色し、紙の色も変色してしまうことがあった。
文字などを印刷した場合、茶葉あるいは茶殻により表面に若干の凹凸があるため印刷文字などの欠け・かすれができ、また、茶葉あるいは茶殻などの色により文字が読みにくくなり、文字視認性が劣るという問題があった。
さらに、近年、茶飲料やコーヒー飲料などの売り上げが増加しており、これらの工場からは多量の茶殻やコーヒー粕などの飲料残渣が排出され、この飲料残渣を、多額の費用をかけて廃棄しなければならないという問題もあった。
However, paper blended with the above tea leaves or tea leaves has poor light resistance because the tea leaves or tea leaves are exposed on the surface of the paper. The color sometimes changed.
When printing letters, etc., the surface of the tea leaves or tea husks has some irregularities, so the printed letters can be chipped or blurred, and the color of the tea leaves or tea husks makes it difficult to read, resulting in poor character visibility. There was a problem.
Furthermore, in recent years, sales of tea beverages and coffee beverages have increased, and a large amount of beverage residues such as tea husks and coffee cakes are discharged from these factories, and these beverage residues are discarded at a high cost. There was also the problem of having to.
そこで、本発明の目的は、飲料残渣粉砕物を配合しつつも文字などがきれいに印刷でき、しかも芳香を有する印刷用紙を提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a printing paper that can print characters and the like neatly while blending a crushed beverage residue, and that has a fragrance.
本発明の印刷用紙は、飲料残渣粉砕物をＸ重量％配合した紙シートの両面に、片面の坪量がＹｇ／ｍ２の飲料残渣粉砕物を配合しない紙シートを抄紙してなることを特徴とする。但し、Ｘは０＜Ｘ≦２５、Ｙは１．６Ｘ≦Ｙ≦１３６を満たす式で表されるものである。 The printing paper of the present invention is formed by paper-making a paper sheet containing no crushed beverage residue having a basis weight of Yg / m 2 on both sides of a paper sheet containing X% by weight of crushed beverage residue. And However, X is represented by a formula that satisfies 0 <X ≦ 25 and Y satisfies 1.6X ≦ Y ≦ 136.
上記印刷用紙は、飲料残渣を、茶殻又はコーヒー粕とすることができる。 In the printing paper, the beverage residue can be tea husk or coffee cake.
また、本発明の印刷用紙は、飲料残渣粉砕物をＸ重量％配合した紙スラリーを抄紙して紙シートを作成し、この紙シートの両面に、片面の坪量がＹｇ／ｍ２となるように紙スラリーを抄紙する工程を有する製造方法により製造することができる。但し、Ｘは０＜Ｘ≦２５、Ｙは１．６Ｘ≦Ｙ≦１３６を満たす式で表される。 In addition, the printing paper of the present invention makes a paper sheet by making a paper slurry containing X weight% of a beverage residue crushed material, and the basis weight of one side is Yg / m 2 on both sides of the paper sheet. It can be manufactured by a manufacturing method having a step of making a paper slurry. However, X is represented by a formula that satisfies 0 <X ≦ 25 and Y satisfies 1.6X ≦ Y ≦ 136.
本発明の印刷用紙は、飲料残渣粉砕物をＸ重量％配合した紙シートの両面に、片面の坪量がＹｇ／ｍ２の飲料残渣粉砕物を配合しない紙シートを抄紙してあり、Ｘを０＜Ｘ≦２５、Ｙを１．６Ｘ≦Ｙ≦１３６の範囲内とすることにより、文字視認性に優れ、芳香のある印刷用紙とすることができる。また、飲料残渣を廃棄することなく有効利用することができる。 In the printing paper of the present invention, a paper sheet not blended with a crushed beverage residue having a basis weight of Yg / m 2 on one side is made on both sides of a paper sheet blended with X% by weight of crushed beverage residue.

本発明の一実施形態の印刷用紙は、飲料残渣粉砕物をＸ重量％配合した紙シートの両面に、片面の坪量がＹｇ／ｍ２の飲料残渣粉砕物を配合しない紙シートを抄紙してなるものであり、Ｘは０＜Ｘ≦２５、Ｙは１．６Ｘ≦Ｙ≦１３６を満たす式で表されるものである。 The printing paper of one embodiment of the present invention is made by paper-making a paper sheet not blended with a crushed beverage residue having a basis weight of Yg / m 2 on both sides of a paper sheet blended with X weight% of a crushed beverage residue. X is represented by a formula satisfying 0 <X ≦ 25 and Y satisfying 1.6X ≦ Y ≦ 136.
飲料残渣粉砕物を配合した紙シートは、例えば、公知の紙パルプに飲料残渣粉砕物を配合して抄紙することにより製造することができる。
紙パルプは、例えば、針葉樹や広葉樹の木チップ、古紙から得られる化学パルプ、再生パルプ、機械パルプなどを用いることができる。
飲料残渣粉砕物は、緑茶、烏龍茶、紅茶、麦茶などの茶飲料の茶殻あるいはこれらの混合茶の茶殻などを粉砕したものやコーヒー飲料のコーヒー粕などを粉砕したものを用いることができる。なかでも、飲料業界から排出される茶飲料の茶殻やコーヒー飲料のコーヒー粕を粉砕したものを好ましく用いることができる。なお、飲料残渣は、粉砕する前に乾燥させず含水した状態で粉砕するのが好ましい。
飲料残渣粉砕物は、特に限定するものではないが、篩にかけ１００μｍ以上１ｍｍ未満の粒径にしておくのが好ましく、この範囲であると抄紙しやすい。
飲料残渣粉砕物の配合率Ｘは、０＜Ｘ≦２５、好ましくは０＜Ｘ≦２０、さらに好ましくは５≦Ｘ≦２０、最も好ましくは５≦Ｘ≦１５の範囲とすることが好ましい。２５重量％より大きいと抄紙時に紙繊維と飲料残渣粉砕物の繊維が絡み合わず抄造不良を起こしやすい。
この紙シートの坪量は、５〜１４４ｇ／ｍ２、特に１３〜１３６ｇ／ｍ２とするのが好ましい。
The paper sheet which mix | blended the drink residue ground material can be manufactured, for example by mix | blending a drink residue ground material with well-known paper pulp, and making paper.
As the paper pulp, for example, softwood or hardwood wood chips, chemical pulp obtained from waste paper, recycled pulp, mechanical pulp, and the like can be used.
As the beverage residue pulverized product, a product obtained by pulverizing a tea beverage such as green tea, oolong tea, black tea, barley tea, or a mixed tea mixture thereof, or a coffee beverage obtained by pulverizing coffee candy or the like can be used. Especially, what grind | pulverized the tea-shell of the tea drink discharged | emitted from the drink industry, and the coffee mash of the coffee drink can be used preferably. In addition, it is preferable to grind | pulverize a drink residue in the state containing water, without drying before grind | pulverizing.
The beverage residue pulverized product is not particularly limited, but is preferably sieved to a particle size of 100 μm or more and less than 1 mm.
The blending ratio X of the crushed beverage residue is preferably 0 <X ≦ 25, preferably 0 <X ≦ 20, more preferably 5 ≦ X ≦ 20, and most preferably 5 ≦ X ≦ 15. If it is larger than 25% by weight, the paper fibers and the fibers of the crushed beverage residue are not entangled at the time of paper making, which tends to cause poor paper making.
The basis weight of the paper sheet, 5~144g / m 2, particularly preferably in the 13~136g / m 2.
飲料残渣粉砕物を配合しない両面に用いる紙シートは、例えば、公知の紙パルプから抄紙することができ、紙パルプは、上記紙パルプと同様のものを用いることができる。
この紙シートの片面の坪量Ｙは、１．６Ｘ≦Ｙ≦１３６（０＜Ｘ≦２５）の範囲とすることが好ましい。１３６ｇ／ｍ２より大きいと印刷用紙から芳香がせず、１．６Ｘ（０＜Ｘ≦２５）より小さいと印刷用紙に印刷した場合、文字視認性が劣るものとなる。
また、両面の紙シートは、坪量が相違していてもよい。
The paper sheet used on both sides not blended with the crushed beverage residue can be made from, for example, a known paper pulp, and the same paper pulp as the paper pulp can be used.
The basis weight Y on one side of this paper sheet is preferably in the range of 1.6X ≦ Y ≦ 136 (0 <X ≦ 25). If it is larger than 136 g / m 2 , the printing paper does not smell, and if it is smaller than 1.6X (0 <X ≦ 25), the character visibility is poor when printed on the printing paper.
Moreover, the basis weights of the double-sided paper sheets may be different.
飲料残渣粉砕物を配合した紙シートと飲料残渣粉砕物を配合しない紙シートとは、同じ紙パルプから抄紙しても相違する紙パルプから抄紙してもよい。 The paper sheet containing the ground beverage residue and the paper sheet not containing the ground beverage residue may be made from the same paper pulp or from different paper pulps.
以下に、本発明の印刷用紙の製造方法の一例を説明する。
茶殻、コーヒー粕などを粉砕して飲料残渣粉砕物とし、この飲料残渣粉砕物を、紙パルプ、水、添加剤を適宜割合で混合した紙スラリーに対して２５重量％以下の割合で混合する。この混合物を網に流し込み、適宜坪数のシート状に形成し、プレス機にて脱水し、中間層を形成する。
これとは別に、紙パルプ、水、添加剤を適宜割合で混合した混合物を網上に流し込み、適宜坪数のシート状に形成し、これをプレス機にて脱水して表面層及び裏面層を形成する。
