Also disclosed are multicomponent fibers comprising a water dispersible sulfopolyester having a Tg of at least 57° C. 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 water-dispersible 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.

Abstract: The invention relates to fibers, particularly binder fibers, made from polyesters and the polyesters themselves.

Typically, the polyesters of the invention are semicrystalline and/or crystalline and have a specific melting point ranging from about 140 to about 185° C. The polyesters of the invention may be formed into a variety of products, especially binder fibers for nonwoven fabrics, textile/industrial yarns and fabrics, composites and other molded articles.

Abstract: Disclosed are novel composite fibrous structures which have utility as filters. These composite structures have at least two layers. The first layer is a nonwoven fibrous structure made from uniquely grooved fibers. The second layer is of a fibrous material that offers high filter efficiency.. The first layer has significantly lower pressure drop and higher dust holding capacity than the second layer.

Abstract: This invention relates to spinnerets having orifices of unique cross-sections, the spinnerets being useful for extruding therethrough filaments having "U" and "E" shaped cross-sections with stabilizing legs. The use of strategically placed stabilizing legs allow the filaments to maintain the desired shape. The "U" shaped filament cross-section provides improved drainage over previous filament cross-sections.
