    摘要： Disclosed are water-dispersible fibers derived from sulfopolyesters having a Tg of at least 250C. The fibers may contain a single sulfopolyester or a blend of a sulfopolyester with a water-dispersible or water-nondispersible polymer. Also disclosed are multicomponent fibers comprising a water dispersible sulfopolyester having a Tg of at least 570C and a water non-dispersible polymer. The multicomponent fibers may be used to produce microdenier fibers. Fibrous articles may be produced from the water-dispersible fibers, multicomponent fibers, and microdenier fibers. The fibrous articles include waterdispersible and microdenier nonwoven webs, fabrics, and multilayered articles such as wipes, gauze, tissue, diapers, panty liners, sanitary napkins, bandages, and surgical dressings. Also disclosed is a process for water-dispersible fibers, nonwoven fabrics, and microdenier webs. The fibers and fibrous articles have further applications in flushable personal care and cleaning products, disposable protective outerwear, and laminating binders.

    摘要： 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, 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, and wherein said poly(ethylene) terephthalate has an inherent viscosity of less than 0.55 dL/g. 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.
