Abstract: An interlining material comprising a web of non-woven fibers, said web having a first zone having distributed uniformly therein a binder, said first zone disposed proximate to but not in contacting relationship with a second zone having distributed uniformly therein a binder, the binding characteristics of said first zone being distinctly different from the binding characteristics of said second zone, said zones being interconnected by an intermediate zone, said intermediate zone containing a mixture of the binder of said first zone and the binder of said second zone, said intermediate zone having binding characteristics intermediate that of said first and second zone, the binders of said first and second zones merging with one another in said intermediate zone; a method of making an interlining material by uniformly applying to a first zone of a web of non-woven fiber a binder such as a liquid binder so that said zone has a uniform binder content therein, and applying to a second zone proximate thereto but n

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.
