Abstract
A non-shedding hybrid nonwoven web comprised of 99% by mass of functional material(s) co-mingled with the filaments. High level of particle retention within the fabric is provided without the aid of adhesives, binders, adhesive polymers, or post processes. This composite web has a multi-layered structure with a uniform distribution of sorptive particles and desired opposed color contrast on each side. The process includes providing two converging streams of blown polymeric filaments, passive feed of functional material(s) in between the filament streams, and collecting the hybrid webs.
