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 not contiguous therewith a binder so that said second zone has a uniform binder content, the binder content of said first and second zones such that said zones have different binding characteristics.
