ABSTRACT:
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.
