Abstract
A hollow fiber that extending along at least a portion of the fiber along a longitudinal axis thereof and is defined by an interior wall is provided. Through selective control over the manner in which it is formed, the present inventors have discovered that the hollow fiber can exhibit a unique combination of a high void fraction and small fiber size that makes it particularly suitable for use in certain applications, such as in nonwoven webs for absorbent articles.
