Patent number: 8691130Abstract: Disclosed are multicomponent fibers derived from a blend of a sulfopolyester with a water non-dispersible polymer wherein the as-spun denier is less than about 6 and wherein the water dispersible sulfopolyester exhibits a melt viscosity of less than 12,000 poise measured at 240° C. at a strain rate of 1 rad/sec, and wherein the sulfopolyester comprising less than about 25 mole % of residues of at least one sulfomonomer, based on the total moles of diacid or diol residues. The multicomponent fiber is capable of being drawn at a relatively high fiber speed, particularly at least about 2000 m/min, and may be used to produce microdenier fibers. Fibrous articles may be produced from the multicomponent fibers and microdenier fibers. Also disclosed is a process for multicomponent fibers, nonwoven fabrics, and microdenier webs.Type: GrantFiled: December 22, 2010Date of Patent: April 8, 2014Assignee: Eastman Chemical CompanyInventors: Rakesh Kumar Gupta, Scott Ellery George, Daniel William Klosiewicz, Kab Sik Seo, Coralie McKenna Fleenor, Allen Lynn Crain
