Claims24
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.
5 more elements
A method of sizing a warp, said method comprising:
- applying a recycled warp sizing composition to a warp, wherein the recycled warp sizing composition comprises:
- at least one film-forming agent and a nonionic surfactant system comprising at least one polyoxyethylated laurate surfactant and at least one polyoxyethylated castor oil surfactant.
A method of sizing a warp, said method comprising:
- applying a warp sizing composition to a warp, wherein the warp sizing composition comprises:
- at least one film-forming agent and a nonionic surfactant system comprising at least one polyoxyethylated laurate surfactant and at least one polyoxyethylated castor oil surfactant.
