Abstract
In a process of making an absorbent article such as a sanitary napkin or a disposable diaper, hydrophilic fibers and crimped or coiled synthetic fibers are supplied in a single fiberboard to a defiberising means such as a hammermill. The process results in a homogenous and resilient blended absorbent core that can be produced using a single defiberising unit. The crimped or coiled fibers pass through the defiberising means without their two or three-dimensional structure being adversely affected at a relatively low defiberisation energy.
