Abstract

The disclosed invention relates to split fibers and improved means and methods for obtaining them as well as their use in nonwovens and incorporation into personal care and other products.
Multicomponent filaments are formed including at least two incompatible components. These filaments are drawn under hot aqueous, for example, steam, conditions causing them to split into fibers containing the incompatible components. These fibers are collected as a fine fiber nonwoven which finds utility as a component of sanitary napkins, diapers and other products.
