Abstract

La présente invention concerne un filament composé de type côte-à-côte à retrait élevé, dans lequel deux types de polymères thermoplastiques sont juxtaposés, et un retrait à l'eau bouillante (Sr2), mesuré par la méthode décrite au paragraphe 5.10 de JIS L 1090 (charge initiale = denier notifié x 1/10 g; charge statique = denier notifié x 20/10 g), correspond à 20 à 75 % de retrait à l'eau bouillante (Sr1), mesuré par la méthode décrite au paragraphe 7.15 de JIS L 1013 (charge initiale = denier notifié x 1/30 g; charge statique = denier notifié x 40/30 g). Le filament composé de type côte-à-côte de l'invention est constitué de deux types de polymères thermoplastiques présentant une variation du poids moléculaire moyen en nombre (ΔMn) de 5.000 à 15.000 après filature. Le filament composé est étiré et soumis à un traitement thermique propre à lui conférer les propriétés physiques suivantes: a) une plage de température présentant une contrainte thermique maximale de 95 % (Tmax, 95%): 120 à 230 °C; b) une gamme de contrainte thermique maximale par denier: 0,1 à 0,4 g/denier.
