A technique for incorporating a liquid additive into a nonwoven web is
disclosed. Specifically, the liquid additive is loaded into filler
particles to form a "dry liquid concentrate", i.e., pulverulent granular
solid or powder loaded with the liquid additive. The incorporation of the
liquid additive into dry liquid concentrates provides a variety of
benefits. For example, prior to extrusion, the dry liquid concentrates
generally retain the properties of filler particles from which they are
formed as the liquid remains isolated. In this manner, a higher level of
the liquid additive may be compounded with a melt-extrudable base
composition without adversely affecting the extrusion process. Only upon
extrusion of the composition will a significant portion of the liquid
additive be released to provide the desired properties to the resulting
nonwoven web.
