Patent

CA 2390130

A method of treating fabric comprising dyed cellulosic fibres to increase its photostability comprises applying to the fabric a substance which is absorbed into and/or coated on to the fibres such that the diffusion of atmospheric oxygen into and/or within the fibres is inhibited. The method may be carried out as part of a laundering process or an industrial textile treatment. The method is particurlarly effective when the compound is used in conjuction with a sunscreen such as a benzotriazole.

La présente invention concerne un procédé de traitement de tissu comprenant des fibres cellulosiques teintes, qui permet d'améliorer la photostabilité dudit tissu. Ce procédé consiste à appliquer sur le tissu une substance qui est absorbée dans et/ou appliquée sur les fibres, de façon que la diffusion d'oxygène atmosphérique dans et/ou à l'intérieur des fibres est inhibée. Ce procédé peut faire partie d'un processus de blanchissage ou d'un traitement de textile industriel. Ce procédé est particulièrement efficace lorsque le composé est utilisé en association avec un écran solaire, tel qu'un benzotriazole.
