It refers to a continuous, extremely long fiber, and in Japan, long fibers are called filaments, including cellulose-based fibers and synthetic fibers. Raw silk, rayon, nylon, and other fibers can be spun to produce threads of nearly infinite length, but these single fibers are called filaments. In the case of rayon, a single fiber is called a monofilament, or monofil for short, and a multifilament is a single fiber made from a finer fiber (thickness) than normal fibers and spun to the same fineness as a single fiber. The fineness of the fiber spun varies depending on the application, but is generally around 3 denier to 20 denier. When this is used as raw yarn for knitting or weaving, it can be reeled in and used untreated, or it can be processed like wool (textured yarn) by applying appropriate heat treatment.

連続したきわめて長い繊維をさし、日本では繊維素系の繊維と合成繊維を通じて、長繊維のものをフィラメントとしている。生糸・人絹・ナイロンなどの紡出した繊維は、無限に近い長さの糸が得られるが、この単繊維をさしてフィラメントとよんでいる。人絹糸の場合では、この単繊維1本からなるものをモノフィラメントmonofilamentまたは略してモノフィルmonofilとよび、普通品より細い繊度(繊維の太さ)の単繊維を使って単繊維と同じ繊度にしたものをマルチフィラメントmultifilamentまたは略してマルチmultiとよんでいる。紡出に際しての繊度は、用途によってまちまちであるが、一般に3デニールから20デニールぐらいのものが多い。これを編物用・織物用原糸とするときは、そのままリールにとり、未処理のまま使用することもあるが、それに適した熱処理などを施し、羊毛のように加工(テックスチャード・ヤーン)して使用する。 [角山幸洋] 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
