ABSTRACT:
A method of producing a nonwoven fabric from a web of fibers, said fibers being substantially nonreactive to microwave energy, comprising applying a microwave reactive material to fibers in said web, subjecting the web to microwave energy at a temperature and for a time to heat said microwave reactive material sufficiently to cause bonding at at least some of the fiber intersections in said web thereby producing a nonwoven web. The resulting nonwoven fabric has a number of uses and is especially suitable as primary carpet backing.
