Title (EN) LOW-ELUTION POLYETHYLENE-BASED FIBERS AND NONWOVEN FABRIC USING SAME
(FR) FIBRES À BASE DE POLYÉTHYLÈNE À FAIBLE ÉLUTION ET TEXTILE NON-TISSÉ UTILISANT CELLES-CI
Abstract:
(EN) The invention is contemplated for providing polyethylene-based fibers in which elution of metal from polyethylene is suppressed as much as possible. The invention relates to polyethylene-based fibers, composed of at least one kind of polyethylene resin, in which a total of content of metal elements such as Na, K, Ca, Fe, Cu, Mg, Mn, Li, Al, Cr, Ni and Zn contained inside the fibers is 40 ppm or less. Moreover, the invention relates to a nonwoven fabric using the polyethylene-based fibers.
(FR) La présente invention concerne la fourniture de fibres à base de polyéthylène dans lesquelles l’élution de métal à partir du polyéthylène est réduite au minimum. L’invention concerne des fibres à base de polyéthylène, composées d’au moins un type de résine de polyéthylène, dans lesquelles la teneur totale d’éléments métalliques tels que Na, K, Ca, Fe, Cu, Mg, Mn, Li, Al, Cr, Ni et Zn contenus à l’intérieur des fibres est de 40 ppm ou moins. L’invention concerne en outre un textile non-tissé utilisant les fibres à base de polyéthylène.
