CA 2394722

There is provided a method of delivering a benefit agent to fabric for exerting a pre-determined activity, wherein the fabric is pre-treated with a multi-specific binding molecule which has a high binding affinity to said fabric through one specificity and is capable of binding to said benefit agent through another specificity, followed by contacting said pre-treated fabric with said benefit agent, to enhance said pre-determined activity to said fabric. Preferably, the binding molecule is an antibody or fragment thereof, or a fusion protein comprising a cellulose binding domain and a domain having a high binding affinity to another ligand which is directed to said benefit agent. The method is useful for example for stain removal, perfume delivery, and treating collars and cuffs for wear.

L'invention porte sur un procédé d'application d'un agent bénéfique sur un tissu ayant été prétraité par une molécule de liaison plurispécifique présentant une forte affinité de fixation avec ledit tissu en raison d'une spécificité, et pouvant se fixer audit agent bénéfique en raison d'une autre spécificité, ledit tissu prétraité étant ensuite mis en contact avec l'agent bénéfique pour augmenter ladite activité prédéterminée. La molécule de liaison est de préférence un anticorps ou l'un de ses fragments ou une protéine de fusion comportant un domaine de fixation de cellulose présentant une forte activité de fixation avec un autre ligand s'adressant à audit agent bénéfique. Le procédé peut par exemple s'utiliser pour éliminer des taches, diffuser un parfum, ou traiter les cols ou les manchettes contre l'usure.
