Abstract
A surface material for absorptive products comprising a succession of fluid permeable surface layers comprising a nonwoven fabric, an absorptive layer and a backing layer unpervious to fluid being provided, the nonwoven fabric comprising fibers of which surface of 50% or more being occupied by a hydrophobic resin, and a 0.1 to 1.0 weight % of a finishing agent being deposited onto the surface of the fibers. The finishing agent comprises a mixture of a sorbitan monooleate with a polyoxyethylene sorbitan monooleate in a weight ratio of 1:1 to 9:1. The fibers may further contain a specific wetting agent.
