Patent ID: 7470464

Claim:
A fiber material having improved malodor scavenging properties, the fiber material comprising: (a) fibers; and (b) dispersed within the fibers, an effective malodor scavenging amount of at least one of (i) particles of zinc, wherein the amount of particles of zinc in the fiber material is in a range from about 0.015 to 1 wt.-%, based on the fiber material, and wherein the particles of zinc are essentially free of corresponding oxides and the particles of zinc are nanosized particles having an average diameter in a range of 40 to 250 nm and (ii) a cyclodextrin material, wherein the cyclodextrin is free of an inclusion complex compound and the cyclodextrin comprises an α-cyclodextrin, a β-cyclodextrin, a γ-cyclodextrin or mixtures thereof, having pendant moieties or substituents that render the cyclodextrin compatible with the fiber material, wherein the malodor scavenging amount is physically mixed into the fibers of the fiber material by extrusion, the cyclodextrin comprising at least one substituent having an alkyl ester group.
