This application discloses multicomponent fibre, it is derived from the blend of the polymer that sulfonic polyester and water can not disperse, wherein just spin dawn number and be less than about 6 and wherein the dispersible sulfonic polyester of water demonstrates melt viscosity and is less than 12,000 pool, measure under the strain rate of 1 radian per second at 240 DEG C, and wherein sulfonic polyester comprises the residue of at least one sulfomonomer being less than about 25mol%, based on the total mole number of diacid or diol residue.Multicomponent fibre in higher fiber speed, particularly at least about 2000m/min, can stretch, and may be used for producing micro-dawn number fiber.Fibre can by multicomponent fibre and micro-dawn number procedure of fibre production.Also disclose a kind of method for multicomponent fibre, supatex fabric and micro-dawn number net. |
