Description
【００４１】
J＝λ/2sin［｛tan-1(r/R)｝/2］
J ：長周期（nm）
R ：カメラ半径（405mm）
λ：Ｘ線の波長（0.15418nm）
Ｋ．仮撚加工糸の捲縮特性、CR値
仮撚加工糸をかせ取りし、実質的に荷重フリーの状態で沸騰水中15分間処理し、24時間風乾した。このサンプルに0.088cN/dtex（0.1gf/d）相当の荷重をかけ水中に浸漬し、2分後のかせ長L'0を測定した。次に、水中で 0.0018cN/dtex（2mgf/d）相当の微荷重に交換し、2分後のかせ長L'1を測定した。そして下式によりCR値を計算した。[0041]
J = λ / 2 sin [{tan -1 (r / R)} / 2]
J: Long period (nm)
R: Camera radius (405 mm)
λ: wavelength of X-ray (0.15418 nm)
K. Crimping property of false-twisted yarn, CR value False-twisted yarn was squeezed, treated in boiling water for 15 minutes in a substantially load-free state, and air-dried for 24 hours. A load corresponding to 0.088 cN / dtex (0.1 gf / d) was applied to this sample to immerse it in water, and the skein length L'0 after 2 minutes was measured. Then, replace the 0 .0018cN / dtex (2mgf / d ) fine load equivalent in water was measured skein length L'1 after 2 minutes. And CR value was calculated by the following formula.
