Patent ID: 7018425

Claim:
A method of reclaiming warp sizing components, said method comprising: desizing a woven fabric to produce a liquor, wherein the woven fabric prior to desizing comprises fibrous material at least partially coated with a warp sizing composition containing: an original amount of at least one film-forming agent and a nonionic surfactant system comprising an original amount of at least one polyoxyethylated laurate surfactant and an original amount of at least one polyoxyethylated castor oil surfactant; processing the liquor to separate one or more warp sizing components from other warp sizing components; wherein the one or more warp sizing components comprise: (a) at least 50 percent by weight of the original amount of the at least one polyoxyethylated laurate surfactant, based on a total weight of the original amount of the at least one polyoxyethylated laurate surfactant; (b) at least 50 percent by weight of the original amount of the at least one polyoxyethylated castor oil surfactant, based on a total weight of the original amount of the at least one polyoxyethylated castor oil surfactant; and (c) at least 50 percent by weight of the original amount of the at least one film-forming agent, based on a total weight of the original amount of the at least one film-forming agent.
