A method for treating carpets is provided which obviates the need for scouring. In accordance with the method, an unscoured carpet is treated topically, and by means of a low wet pickup method, with a solution comprising particles of silica or a similar inorganic additive and a fluorochemical or other optional organic additive. Carpets treated in accordance with this method are found to have excellent soil resistance properties which do not decrease noticeably with subsequent wear or cleaning. Furthermore, since the method involves a low wet pickup, the required drying times are significantly reduced as compared to conventional aqueous bath immersion methods.

Cette invention concerne un procédé de traitement de tapis qui permet d'éviter tout recours à un lavage industriel. D'après ce procédé, le tapis non lavé est traité en surface, selon un procédé de ramassage à faible mouillage, à l'aide d'une solution qui comprend des particules de silice, ou un additif organique similaire, ainsi qu'un agent fluorochimique ou un éventuel autre additif organique. Les tapis traités selon ce procédé possèdent d'excellentes propriétés de résistance aux salissures qui ne s'estompent que très peu à l'usure ou après des lavages. En outre, étant donné que ce procédé fait appel à un ramassage avec un faible mouillage, la durée de séchage peut être sensiblement réduite par rapport aux procédés traditionnels d'immersion dans des bains aqueux.
