Title
(EN) MULTICOMPONENT SELF-BULKING FIBERS
(FR) FIBRES AUTO-GONFLANTES À COMPOSANTS MULTIPLES
Abstract
(EN) The present invention provides multicomponent fibers designed to curl in response to external stimuli such as heat or moisture. The multicomponent fiber can have cross-sectional area comprising the first polymer component and the second polymer component, wherein the first polymer component and the second polymer component are configured in an eccentric sheath/core arrangement and wherein the core component has a non-circular shape. Also, the multicomponent fiber has a first cross-sectional center of mass and a cross-sectional periphery, the core component has a second cross-sectional center of mass; and the second cross-sectional center of mass is positioned from about 20 percent to about 70 percent of the distance from the first cross-sectional center of mass to a point on the cross-sectional periphery. Furthermore, the present disclosure provides a fabric including a plurality of multicomponent fibers designed to curl in response to external stimuli such as heat or moisture.
(FR) La présente invention concerne des fibres à composants multiples conçues pour se boucler en réponse à des stimuli externes tels que la chaleur ou l'humidité. La fibre à composants multiples peut présenter une section transversale qui comprend le premier composant polymère et le second composant polymère, le premier composant polymère et le second composant polymère étant conçus en un agencement excentrique gaine/âme et le composant âme présentant une forme non circulaire. En outre, la fibre à composants multiples présente un premier centre de masse de section transversale et une périphérie de section transversale, le composant âme présente un second centre de masse de section transversale ; et le second centre de masse de section transversale est positionné d'environ 20 % à environ 70 % de la distance du premier centre de masse de section transversale de masse à un point sur la périphérie de section transversale. La présente invention concerne en outre un tissu qui comprend une pluralité de fibres à composants multiples conçues pour se boucler en réponse à des stimuli externes tels que la chaleur ou l'humidité.
