理にも用い得るものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a polypropylene blend paper and a molded article formed from the polypropylene blend paper, particularly a food container. The molded article of the present invention can be used not only for freezing and refrigerating foods, but also for thawing, heating, and cooking frozen foods using a microwave oven or the like.

器を製造することは難しかった。To solve the problem of difficulty in incineration, food containers made of natural bulbs have also been used in some cases. but,
Since most of these food containers are manufactured only from natural valves, they have drawbacks in terms of water resistance and oil resistance. Furthermore, it has been difficult to produce a good tray-shaped food container by press working.
本発明は、ポリプロピレン混抄紙、及びこのポリプロピ
レン混抄紙から成形した成形品に関する。The present invention relates to a polypropylene mixed paper and a molded article formed from this polypropylene mixed paper.
本発明のポリプロピレン混抄紙及び成形品は焼却が容易
なうえ、耐水性、耐油性、耐熱性、及びプレス加工性に
も優れている。The polypropylene mixed paper and molded articles of the present invention are not only easy to incinerate, but also have excellent water resistance, oil resistance, heat resistance, and press workability.
本発明のポリプロピレン混抄紙は、パルプとポリプロピ
レン繊維とからなっており、以下のような製法で作られ
る。The polypropylene mixed paper of the present invention is made of pulp and polypropylene fibers, and is produced by the following manufacturing method.
先ず、繊維油剤を表面に付着させたポリプロピレン繊維
を、パルプを水に懸濁させたバルブ縣濁液中に分散させ
、抄紙ａＳ液とする。次いで、この抄祇縣濁液を抄紙機
でウェットシートに漉き上げて、プレスしドライヤーで
乾燥すると本発明のポリプロピレン混抄紙が得られる。First, polypropylene fibers having a fiber oil adhered to their surfaces are dispersed in a valve suspension in which pulp is suspended in water to obtain a papermaking aS solution. Next, this paper suspension is strained into a wet sheet using a paper machine, pressed, and dried using a drier to obtain the polypropylene mixed paper of the present invention.
ポリプロピレン繊維の表面に繊維油剤を付着させるのは

ロピレン繊維の表面に付着させて親水性とし、バルブ縣
濁液中でも均一に分散するようにしたのである。The reason why fiber oil is applied to the surface of polypropylene fibers is as follows. Since polypropylene fibers are hydrophobic as they are, they are not uniformly dispersed in the pulp suspension, making it impossible to obtain a good pulp suspension. Therefore, a fiber oil was attached to the surface of polypropylene fibers to make them hydrophilic, so that they could be uniformly dispersed even in the valve suspension.

たものである。In the polypropylene mixed paper of the present invention, the proportions of pulp and polypropylene fibers are (a) pulp: 90 to 20% by weight, (b) polypropylene fibers: 10 to 80% by weight. The polypropylene fiber has (a) a fineness of 0.5 to 20 deniers, and b) a cut length of 1 to 3
0 mm, and (c) a fiber oil of 0.03 to 2 times the weight of polypropylene fibers) is attached to the fiber surface.

又、ポリプロピレン繊維の割合が８０重量％を超えると
、焼却時に大きな熱量を発生するようになり、焼却が困
難になる。Furthermore, if the proportion of polypropylene fibers exceeds 80% by weight, a large amount of heat will be generated during incineration, making incineration difficult.
本発明において、パルプとしては、ＮＢＫＰ。In the present invention, the pulp is NBKP.

の効果を損なわない範囲で含有していてもよい。Moreover, polypropylene fiber is a fiber obtained by spinning polypropylene or a copolymer of propylene and ethylene or other α-olefin. Polypropylene and the like may contain antioxidants, ultraviolet absorbers, lubricants, fillers, etc., to the extent that they do not impair the effects of the Zero 1 invention.
ポリプロピレン繊維は繊度０．５〜２０デニールのもの
でなくてはならない。繊度０．５デニ一ル未満のものを
用いると、ポリプロピレン混抄紙の強度が低下するとい
う問題がある。一方、繊度が２０デニールを超えるとポ
リプロピレン混抄紙の表面状態が悪化する。The polypropylene fibers must have a fineness of 0.5 to 20 denier. If a material having a fineness of less than 0.5 denier is used, there is a problem that the strength of the polypropylene mixed paper decreases. On the other hand, if the fineness exceeds 20 deniers, the surface condition of the polypropylene mixed paper deteriorates.
ポリプロピレン繊維のカット長さは３〜１０ＩＩＩＩ１
１であることが必要である。The cut length of polypropylene fiber is 3 to 10III1
Must be 1.

長さが１０１ｎｌ！ｌを超えると、ポリプロピレン繊維
がバルブ縣濁液中に均一に分散しにくくなる。If the cut length is less than 3 tan, there is a problem that the strength of the polypropylene mixed paper decreases. - On the other hand, the cut length is 101nl! If it exceeds 1, it becomes difficult for the polypropylene fibers to be uniformly dispersed in the bulb suspension.
ポリプロピレン繊維の表面に付着させる繊維油剤の量は
、０．０３〜２重量％（ポリプロピレン繊維に対して）
の範囲である必要がある。The amount of fiber oil attached to the surface of polypropylene fibers is 0.03 to 2% by weight (based on polypropylene fibers).
must be within the range.

ポリプロピレン混抄紙をプレス等で成形すると、成形品
のコーナ一部に破れが生じる場合がある。If the amount of fiber oil attached is less than 0.03% by weight, the polypropylene fibers will not be uniformly dispersed in the pulp suspension, resulting in poor papermaking. A cloudy liquid cannot be obtained. When polypropylene mixed paper made from this paper suspension is molded using a press or the like, tears may occur at some corners of the molded product.
繊維油剤の量が２重１％を超えると、バルブ縣濁液にポ
リプロピレン繊維を分散させる際に、パルプ縣濁液が著
しく泡立ち作業性が悪くなる。If the amount of fiber oil exceeds 1% by weight, the pulp suspension will foam significantly when polypropylene fibers are dispersed in the valve suspension, resulting in poor workability.
尚、ポリプロピレン繊維表面には、繊維油剤とともに水
分が付着していると、抄紙懸濁液中での分散性がさらに
良くなるので好ましい。但し、水分の付着量は１００重
量％（ポリプロピレン繊維に対して）以下が好ましい。Incidentally, it is preferable that water is attached to the surface of the polypropylene fiber together with the fiber oil, since this further improves the dispersibility in the papermaking suspension. However, the amount of water attached is preferably 100% by weight or less (based on the polypropylene fiber).
水分の付着量が１００重量％を超えると、梱包時や輸送
時、保管時に水分が滲み出す等の問題が生じやすい。又
、ｉｔが大きくなり過ぎ、取扱や輸送コストが高くつく
等の問題もおこる。If the amount of moisture attached exceeds 100% by weight, problems such as moisture oozing out during packaging, transportation, and storage are likely to occur. Further, problems such as the IT becoming too large and the handling and transportation costs becoming high also occur.
