Staple Fiber

Abbreviated as "staple fiber." Continuous long fibers (filaments) cut to an appropriate length with a cutter to be used as raw material for spinning and other processes. Originally it meant cut rayon, but now it is widely used to refer to cut short fibers of various man-made fibers. The length and thickness of the fibers vary depending on the purpose. Many are short fibers that have been given a curl (crimp) to make them easier to spin (spinnability), to increase the intertwining of the fibers (cohesion), and to increase bulk.

略称スフ．連続した長繊維(フィラメント)を紡績などの原料にするため，カッターで適当な長さに短く切断したもの．最初はレーヨンを切断したものを意味したが，現在では各種の人造繊維の切断した短繊維に広く用いられる．繊維の長さ，太さはそれぞれ目的に応じて変わる．紡績の容易さ(可紡性)，繊維相互のからみあい(抱合性)，かさばりを増すために短繊維にちぢれ(けん縮，クリンプ)を付与したものが多い．
