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.

[ What is claimed is:] [1.] A method of making an absorbent batt, the method comprising the steps of:providing a fiber board comprising a first type of fibers that are hydrophilic and a second type of fibers that are synthetic, multi-dimensional and crimped, said multi-dimensional, crimped synthetic fibers having an average extended length of between 2 and 25 mm, a denier of between 6 and 40, and between 3 and 8 crimps or coils per inch, said two types of fibers being mixed and compressed wherein said multi-dimensional, crimped synthetic fibers are able to be defiberized without being destroyed, the percentage of said multi-dimensional, crimped synthetic fibers in said fiber board being at least 10% by weight;supplying said fiber board to a defiberising means for forming individualized fibers or groups of fibers;defiberising said fiber board substantially without substantial plastic deformation of said multi-dimensional, crimped synthetic fibers; andtransporting said defiberised fibers to a core forming means for forming an absorbent batt.
