ABSTRACT:
A process for chemically bonding an odor-encapsulating agent to textiles includes reacting a cyclodextrin with a cross-linking agent capable of forming ether bonds with the cyclodextrin and with the textile material, and curing the textile material treated with a mixture of the cyclodextrin and cross-linking agent. Preferably, the cross-linking agent is imidazolidone, which forms an ether bond with a hydroxyl group on the cyclodextrin and with a hydroxyl group. In textile materials containing cellulose, imidazolidone forms an ether bond with a hydroxyl group on the cellulose. An active agent can be complexed with the cyclodextrin for release. Textiles formed by such a process can comprise an article of clothing adapted to trap odors emanating from a wearer.
