Attorney, Agent or FirmInternational ClassD04H 005/00AbstractA nonwoven fabric having high performance aqueous fluid retention and wiping characteristics and a method of producing such fabric. The fabric comprises a reinforcing web of self-bonded continuous filament synthetic fibers having at least one surface with spaced clusters of synthetic staple fibers and short natural fibers generally surrounded by void areas having a concentration of synthetic staple fibers and short natural fibers which is lower than such concentration in the clusters. The desired pattern of clusters may be obtained by hydroentanglement using a coarse apertured forming surface. | |
