Abstract
A suede-like sheet material closely resembling natural leathers in feel and nap is produced by temporarily fixing a fibrous mat consisting of 'oceano-insular' composite fibers, impregnating said fibrous mat with elastomer (A), smoothing the surface, impregnating the resulting mat with another elastomer (B) which is harder and less swellable than said elastomer (A), removing the sea or matrix component of the composite fiber, and napping the surface of the resulting sheet material.
