Technique for incorporating a liquid additive into a nonwoven web

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