Two-step process for treating fabric via multispecific binding molecules

Abstract From the Canadian patent

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 …
