Title (EN) SPUNBOND NONWOVEN FABRIC
(FR) TISSU NON-TISSÉ FILÉ-LIÉ
(JA) スパンボンド不織布
Abstract:
(EN) Provided is a spunbond nonwoven fabric which is made of a polypropylene fiber and satisfies all of the following conditions A to E: A. the average single fiber diameter of the fiber is 6-17 μm; B. the degree of crystal orientation of the fiber as obtained by wide-angle X-ray diffraction is at least 0.91; C. the crystallite size of the (110) plane of the fiber as obtained by wide angle X-ray diffraction is at least 12 nm; D. the average orientation parameter of the fiber as obtained by Raman spectroscopy is at least 8.0; and E. the complex viscosity of the spunbond nonwoven fabric at a temperature of 230°C is 20-100 Pa·sec at an angular frequency of 6.3 rad/sec.
(FR) Le tissu non-tissé filé-lié de l'invention est constitué de fibres de polypropylène, et satisfait l'ensemble des conditions A à E. A. diamètre de fibre unique des fibres supérieur ou égal à 6μm et inférieur ou égal à 17μm, B. degré d'orientation cristalline dans une diffraction de rayons X grand angle des fibres, supérieur ou égal à 0,91, C. taille de cristallite d'un plan (110) dans une diffraction de rayons X grand angle des fibres, supérieure ou égale à 12nm, D. paramètre moyen d'orientation dans une spectroscopie Raman des fibres, supérieur ou égal à 8,0, et E. viscosité complexe à une température de 230°C du tissu non-tissé filé-lié et à une fréquence angulaire de 6,3rad/sec, supérieure ou égale à 20Pa・sec et inférieure ou égale à 100Pa・sec.
