…(1) Chemical fiber machinery In the past, this meant machines for producing rayon, but nowadays there are more machines for producing synthetic fibers. There are spinning machines that extrude liquefied raw materials through small holes to produce fibers, stretching and heat treatment machines that stretch and strengthen the fibers, and crimping machines (false twisting machines and others) that create wool-like crimps. Long fibers are cut to produce short fibers, and spun yarn is made using machines similar to those used for natural fibers, but there are also tow spinning machines unique to chemical fibers. … *Some of the terminology used in reference to "stretching and heat treatment machines" is listed below.

…(1)化学繊維機械 昔はレーヨンを製造する機械のことであったが,最近では合成繊維を製造する機械のほうが多い。液状にした原料を小さな穴から押し出して繊維を作る紡糸機械,さらに繊維を引き伸ばして強くする延伸・熱処理機,羊毛のような巻縮を作るための巻縮加工機(仮撚(かねん)加工機その他)などがある。長繊維を切断して短繊維を作り,天然繊維と同様な機械で紡績糸が作られるが,化繊独特のトウ紡績機械もある。… ※「延伸・熱処理機」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
