Abstract

L'invention concerne un agent pour éviter les phénomènes de décoloration et grisaillement de textiles, selon lequel il est prévu d'utiliser un substrat fixant les colorants, à base de cellulose cationisée se présentant sous forme de fibres coupées cationisées et/ou de segments de fils pour corde cationisés. Ledit agent peut contenir des substances tensioactives et destinées à l'entretien de textiles et être introduit dans des récipients récupérables ou dans des récipients jetables. Ledit procédé est particulièrement économique étant donné qu'il fait appel à des déchets tels que des fibres de basse qualité. En outre, les textiles teintés ne subissent pas de décoloration du fait que l'utilisation de récipients empêche tout contact entre le substrat et le linge. Cet agent est particulièrement économique en ce qu'il permet d'utiliser comme substrats, des déchets, ainsi que des fibres et des textiles de basse qualité.
