Title:
生物学的な活性により劣化し易い繊維質材料を処理するための方法及びプラント
Document Type and Number:
Japanese Patent JP2008512572
Kind Code:
A
Abstract:
Material susceptible to degradation by biological activity, before all by microorganisms like bacteria and fungi, is treated with ozone. The ozone penetrates the material and not only deactivate the active organisms themselves, but also spores of bacteria and fungi. The ozonization is performed in at least one cycle consisting of subjecting the material to underpressure, e.g. of 500 mBar, in a vessel, then filling the vessel with ozone containing gas. In a preferred embodiment, the ozonization may be preceded by at least one steaming cycle, consisting essentially of applying vacuum, then filling the vessel with steam, notably with steam of about 80° C.
