A fabric treatment article for use in a clothes dryer comprises a substrate and a fabric treatment composition comprising at least one laundry benefit agent in an amount effective for reducing wrinkles, stains or odours in clothing applied to the substrate. The substrate is either: (i) a sheet having first and second sides, each side having similar dimensions and raised and depressed portions, wherein between 0.02-0.07 grams of the fabric treatment composition is applied per square centimetre of the sheet, (ii) or a sheet with first and second sides having similar dimensions wherein at least part of the first side has one colour and at least a part of the second side has a different colour. Alternatively, the composition comprises between 0.1-5 wt.% of fabric benefit agent selected from ethoxylated organosilicones; polyalkyleneoxide modified polydimethylsiloxane; linear aminopolydimethylsiloxane polyalkyleneoxide copolymers; sulphated/sulphonated vegetable oils; high molecular weight polyacrylamides; betaine siloxane copolymers; or alkylactam siloxane copolymers. A method of reducing the occurance of wrinkles in laundered clothing is also provided.

La présente invention concerne un article de traitement pour textiles destiné à s'utiliser dans un sèche-linge. Cet article comprend un substrat et une composition de traitement des textiles. Cette composition comprend au moins une quantité suffisante d'un agent de blanchisserie améliorant appliqué sur le substrat et permettant d'empêcher en partie le linge de se froisser, et de conserver les tâches ou les odeurs. Ce substrat est soit (i) une feuille définissant deux faces de dimensions semblables comportant des zones en relief et des zones en creux, feuille dans laquelle on a appliqué 0,02 à 0,07 g de composition traitante au cm?2¿, soit (ii) une feuille définissant deux faces de dimensions semblables, mais de couleurs différentes d'une face à l'autre. Selon une autre réalisation, la compositon comprend 0,1 à 5 % en poids d'un agent améliorant appartenant au groupe des organosilicones éthoxylés, polydiméthylsiloxane à modification polyalkylèneoxyde, copolymères linéaires d'aminopolydiméthylsiloxane polyalkylèneoxyde, d'huiles végétales sulfatées ou sulfonées, polyacrylamides à masse moléculaire élevée, copolymères de bétaïne-siloxane ou copolymères d'alkylactam-siloxane. L'invention concerne également un procédé permettant de limiter le froissage du linge sortant de blanchissage.
