The present invention provides a hollow fiber, which includes: at least one thermoplastic polymer with an equilibrium water content of 2% or less; wherein the number of hollow portions (a,) and a hollow ratio (alpha2) in said fiber satisfy the following equations: <paragraph lvl="0"><in-line-formula>alpha1>=7 </in-line-formula><paragraph lvl="0"><in-line-formula>2<=alpha2<=65 </in-line-formula>0.14<=(alpha1xalpha2)/100<=250. Other embodiments of the present invention include articles containing the hollow fiber, methods of making and of using, and a sea-island conjugate fiber
