Title
(EN) A METHOD OF PREVENTING PHOTOBLEACHING OF WOOL AND/OR OTHER NATURAL FIBRES
(FR) PROCEDE DE PREVENTION DE LA DECOLORATION PAR LA LUMIERE DE LA LAINE ET/OU D'AUTRES FIBRES NATURELLES
Abstract
(EN)
A method of treating wool and/or other natural fibres with a chemical compound, the compound undergoing photoyellowing at a similar rate to the rate at which the wool and/or natural fibres undergoes photobleaching. The chemical compound is applied in an amount which ensures the photoyellowing of the chemical compound cancels out the photobleaching of the natural fibres. The chemical compounds are preferably syntans and may consist of condensation products of aromatic sulphonic and/or sulphonic acids. Other suitable compounds include optical brightening agents, tannins, and aromatic sulphonic acids.
(FR)
La présente invention concerne un procédé consistant à traiter la laine et/ou d'autres fibres naturelles au moyen d'un composé chimique, ce composé chimique subissant le jaunissement par la lumière à une cadence semblable à la cadence à laquelle la laine et/ou les fibres naturelles subissent la décoloration par la lumière. Le composé chimique est appliqué en une quantité qui assure un jaunissement par la lumière du composé chimique annulant la décoloration par la lumière des composés chimiques. Les composés chimiques sont préférentiellement des syntans. Ils peuvent être constitués de produits de condensation d'acides sulfoniques aromatiques ou non aromatiques. D'autres composés utilisables sont notamment les azurants optiques, les tanins et les acides sulfoniques aromatiques.
