【発明の詳細な説明】
この発明はシール性の良好なグランドパツキンに関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gland packing with good sealing properties.
従来、グランドパツキンとしては、主としてアスベスト
繊維が用いられている。Conventionally, asbestos fibers have been mainly used as ground packing.
これは、アスベスト繊維は#C維が細く柔軟であると共
に油分の保持性が良く、従ってパツキンとして使用する
際にシール性が良いためである。This is because the #C fibers of asbestos fibers are thin and flexible, and have good oil retention properties, so they have good sealing properties when used as packing.
しかし乍ら、アスベストには硅肺金起し易いという問題
があり、アスベスト繊維以外の天然又は合成!at維を
原料とすることが考えられている。However, asbestos has the problem of being susceptible to silica formation, so it is difficult to use natural or synthetic fibers other than asbestos fibers. It is being considered to use at fiber as a raw material.
しかし乍ら、これらの繊1は、アスベストのモノフィツ
メントの径が0.02〜0.03(単位μ−以下同じ)
と細いのに対し、木s10〜45、麻25、羊毛20〜
25、炭素繊維7〜2oと非常に太く、そのため柔軟性
、油分の保持性に問題がhシ、シール性が不充分であっ
た。However, in these fibers 1, the diameter of the asbestos monofite is 0.02 to 0.03 (unit: μ - the same below).
While it is thin, wood s10~45, linen 25, wool 20~
25, the carbon fiber was very thick, measuring 7 to 2 degrees, and therefore had problems with flexibility and oil retention, and had insufficient sealing performance.
この発明はこのような現状に鐵みてなされ友ものであっ
てアスベスト繊維を用いないが故に硅肺の量論がないシ
ール性の良好なグランドパツキン金提供することを目的
とする。The present invention has been made in view of the current situation, and an object of the present invention is to provide a gland packing metal with good sealing performance and no silicosis stoichiometry because no asbestos fibers are used.
そして、この発明は、上記目的を達成する力めに、天然
繊維または合成繊維をフィブリル化させ抄紙して得た紙
状体をテープ状に細断し、これを撚糸してなる繊維材料
を用いてなること金特最とする。In order to achieve the above object, the present invention uses a fiber material obtained by fibrillating natural fibers or synthetic fibers, cutting the paper into tape shapes, and twisting the tape. It is said to be the best.
使用する繊維はフィブリル化し得るものであれば如何な

ポリアクリル=トリ/I/lh維、芳香族ポリアミド繊
維等の合成繊維があげられる。The fibers used may be of any type as long as they can be fibrillated, such as cellulose fibers such as cotton and hemp;
Examples include synthetic fibers such as polyacrylic tri/I/lh fibers and aromatic polyamide fibers.
フィブリル化は抄紙工程における叩解と同じで;b)、

This is done using a paper beater.
抄紙は通常の抄紙法により行うが、必要に応じて固体で

Visceral fibers have a fineness of 0.2 to 0.8, whereas the aromatic polyamide fibers of the present invention have a fineness of 8 to 10, which is close to 13 to 22 of asbestos TA fibers.
