US 2024/0156653 A1 · Absorbent Web for Surge Protection in Absorbent Articles

Abstract

Nonwoven webs having excellent fluid handling characteristics are disclosed. The nonwoven webs are made from a combination of binder fibers and structure fibers. The structure fibers are made from multicomponent, hollow fibers. The structure fibers include first polymer component zones that alternate with second polymer component zones around the circumference of the fiber. The first polymer component zone is made from a polymer having a lower melting temperature than the polymer contained in the second polymer component zone. In this manner, the fibers have a three-dimensional conformation that produces significant void volume within the nonwoven web.
