Abstract:
A textile structure comprising:electret fibers comprising a fiber-forming material selected from the group consisting of a fiber-forming polymer or a fiber-forming polycondensate,the fibers being coated with an initial amount of a preparation comprising at least one active substance, the active substance comprising a compound having the general formula (I)R.sub.1 R.sub.2 R.sub.3 NO (I)wherein R.sub.1 is selected from the group consisting of hydrogen, an unsubstituted C.sub.1 -C.sub.30 alkyl group, an unsubstituted C.sub.1 -C.sub.30 alkenyl group, an unsubstituted C.sub.1 -C.sub.30 aryl group, a substituted C.sub.1 -C.sub.30 alkyl group, a substituted C.sub.1 -C.sub.30 alkenyl group, and a substituted C.sub.1 -C.sub.30 aryl group, and R.sub.2 and R.sub.3, independently of one another, are selected from the group consisting of hydrogen, an unsubstituted C.sub.1 -C.sub.10 alkyl group, an unsubstituted C.sub.1 -C.sub.10 alkenyl group, and an unsubstituted C.sub.1 -C.sub.10 aryl group, a substituted C.sub.1 -C.sub.10 alkyl group, a substituted C.sub.1 -C.sub.10 alkenyl group, and a substituted C.sub.1 -C.sub.10 aryl group,wherein at least 80 weight % of the initial amount of the preparation volatilizes and is removed from the fibers after exposure of the fibers with the initial amount of the preparation coated thereon to a temperature of 250.degree. C. or less for a period of 20 minutes or less.
