The purpose of this work was to investigate how nonwoven fabrics absorb and diffuse
liquids and to define relevant diffusion parameters, with a special focus on the influence of
fiber diameter on the diffusion process. The nonwoven structures studied were composed
of polyester fibers of different diameters and were manufactured with a
drylaid/needlepunching process. The liquid diffusion properties were evaluated with
decane, a perfectly wetting liquid. Two methods based on vertical wicking (one direction)
and absorption capacity measurements were used. The vertical wicking test results
showed that finer fibers led to higher capillary absorption ability, but to the detriment of liquid
absorption rate. Blending two fibers of different diameters improved the liquid retention
behavior, while maintaining absorption rates that were equivalent to nonwovens with the
coarser fibers. Finally, the different results obtained in the two experimental methods for the
liquid filling ratio are discussed.
