Abstract
(EN) The invention provides a filter fabric for providing anti pathogenic properties which has been coated with a composition comprising (a) 0.0001-99.9999% by weight of a compound of such as zinc pyrithione and (b) 0.0001-99.9999% by weight of an additional zinc salt selected from the group consisting of zinc acetate, zinc propionate, zinc oxalate, zinc benzoate, zinc gluconate, zinc ascorbate, zinc citrate, zinc lactate, zinc glycolate, zinc maleate, zinc fumarate, zinc polyacrylate and zinc polymaleate. The invention also provides a composition for imparting anti-viral properties to a breathable substrate material comprising two or more zinc salts selected from the group consisting of zinc acetate, zinc propionate, zinc oxalate, zinc benzoate, zinc gluconate, zinc ascorbate, zinc citrate, zinc lactate, zinc glycolate, zinc maleate, zinc fumarate, zinc EDTA, zinc glycinate, zinc polyacrylate, zinc polylactate, zinc polyglycolate and zinc polymaleate said zinc salts being present in effective amounts to impart anti-pathogenic properties.
(FR) L'invention concerne un tissu filtrant pour fournir des propriétés anti-pathogènes qui a été revêtu d'une composition comprenant (a) de 0,0001 à 99,9999 % en poids d'un composé de type pyrithione de zinc et (b) de 0,0001 à 99,9999 % en poids d'un sel de zinc supplémentaire choisi dans le groupe constitué par l'acétate de zinc, le propionate de zinc, l'oxalate de zinc, le benzoate de zinc, le gluconate de zinc, l'ascorbate de zinc, le citrate de zinc, le lactate de zinc, le glycolate de zinc, le maléate de zinc, le fumarate de zinc, le polyacrylate de zinc et le polymaléate de zinc. L'invention concerne également une composition pour conférer des propriétés antivirales à un matériau de substrat perméable à l'air comprenant deux sels de zinc ou plus choisis dans le groupe constitué par l'acétate de zinc, le propionate de zinc, l'oxalate de zinc, le benzoate de zinc, le gluconate de zinc, l'ascorbate de zinc, le citrate de zinc, le lactate de zinc, le glycolate de zinc, le maléate de zinc, le fumarate de zinc, l'EDTA de zinc, le glycinate de zinc, le polyacrylate de zinc, le polylactate de zinc, le polyglycolate de zinc et le polymaléate de zinc, lesdits sels de zinc étant présents en quantités efficaces pour conférer des propriétés anti-pathogènes.
