Anti-odour and fragrance finishes

Covering Mostly by spraying of perfumes Easy handling but not free from odour, short-acting, not permanent 

Removal Airing Simple and free of applied chemistry but needs a long time and has restricted efficiency, difficulty of handling large amounts 

Removal Washing out odorous substances Conventional technique with mostly good effects, side effect cleaning but high costs of drying 

Removal Adsorption of odorous substances, e.g. in cyclo-dextrines or on active carbon Permanent to washing and dry cleaning but limited uptake and saturation, requires regeneration, for example by washing with the costs of drying 

Decomposition Ozonisation Very effective, side effect disinfection but need of special equipment, probability of damaging dyestuffs, fluorescent brighteners and sensitive fibres like nylon
