Nonwovens fabrics produced from multicomponent fibers comprising sulfopolyesters

摘要

A process for making a nonwoven fabric is provided comprising: (A) collecting multicomponent fibers to form a non-woven web; wherein the multicomponent fiber comprises at least one water dispersible sulfopolyester and at least one water non-dispersible polymer; wherein said multicomponent fiber has a plurality of domains comprising the water non-dispersible polymer; wherein the domains are substantially isolated from each other by the water dispersible sulfopolyester intervening between the domains; (B) contacting the non-woven web with water at a sufficient temperature and pressure to remove a portion of the water dispersible sulfopolyester thereby forming a microfiber web; and (C) hydroentangling the microfiber web to produce the nonwoven fabric. A process is also provided wherein steps (B) and (C) are combined. Fibrous articles utilizing the nonwoven fabrics are also provided.
