Description
前記短繊維において、繊維径が細すぎるとフィンのサイズが小さくなり、スパイラル捲縮が発現しにくくなる。一方、繊維径が太すぎると、単繊維当たりの自重によりスパイラル捲縮が発現しにくくなる。このため、捲縮を付与する点では、繊維径が１０〜２００μｍの範囲が可能であるが、より捲縮を発現させるためには１５〜９５μｍの範囲がより好ましい。 In the short fiber, if the fiber diameter is too thin, the fin size is reduced, and spiral crimps are hardly exhibited. On the other hand, if the fiber diameter is too large, spiral crimps are difficult to develop due to the own weight per single fiber. For this reason, in terms of imparting crimps, a fiber diameter in the range of 10 to 200 μm is possible, but a range of 15 to 95 μm is more preferable in order to develop crimps.
本発明における繊維充填率は３０〜８０％である事が好ましく、４０〜６０％である事が更に好ましい。３０％未満では、繊維としては高空隙を有しているものの、不織布製造工程通過時に断面潰れ等が生じる為、好ましくない。一方、８０％を越えると、改善効果が小さい繊維構造体しか得られない為、好ましくない。なお繊維充填率は下記式で表される。
繊維充填率（％）＝ （Ｃ／Ｄ） ×１００
Ｃ；繊維軸に直交する断面面積
Ｄ；繊維軸に直交する最外周円の面積
The fiber filling rate in the present invention is preferably 30 to 80%, and more preferably 40 to 60%. If it is less than 30%, although the fiber has high voids, it is not preferable because the cross-section is crushed when passing through the nonwoven fabric manufacturing process. On the other hand, if it exceeds 80%, only a fiber structure having a small improvement effect can be obtained. The fiber filling rate is represented by the following formula.
Fiber filling rate (%) = (C / D) × 100
C: Cross-sectional area D orthogonal to the fiber axis D: Area of the outermost circumference circle orthogonal to the fiber axis
