Abstract: An interlining material comprising a non-woven web of fibers wherein the area of the web comprises at least two distinct zones, each of which said zones has substantially uniform fiber content and extends across the width of said interlining, and in which adjacent zones have different fiber contents, the fibers of said zones merging into the fibers of each adjacent said zone; a method for making an interlining which comprises disposing a first fibrous fleece over a second fibrous fleece so as to define a web having at least two distinct zones, each of which zones have substantially uniform fiber content and adjacent said zones having different fiber contents, and thereafter randomizing the distribution of fibers through the web and merging the fibers of said first fibrous fleece with the fibers of said second fibrous fleece.
