Patent number: 6299651Abstract: A process for imparting long-lasting antimicrobial properties to fabrics is disclosed which entails the diffusion of triclosan esters within each individual fiber of a textile. One preferred method is performed in a standard jet dye bath which requires a high range of temperatures to effectively color fabrics. Dyeing in this manner also involves diffusing compounds within individual fibers; thus, this manner of incorporating dyestuffs and colorants within textile fabrics provides a compatible and effective vehicle for simultaneously introducing triclosan esters within such textile fibers, also. A dye bath application is not required, however, as any procedure which allows contact between a triclosan ester derivative and a fabric at a sufficient temperature and for a sufficient time to effectuate diffusion of the ester within each individual fiber of the fabric is also contemplated within this invention.Type: GrantFiled: September 14, 2000Date of Patent: October 9, 2001Assignee: Milliken & CompanyInventor: Shulong Li

Patent number: 5989296Abstract: A process for recovering a vat dye from a textile using a heated organic solvent. The textile is contacted with a heated organic solvent in which the dye is soluble until dye is extracted from the textile into the solvent to produce a dye-containing solvent solution. The dye is then recovered from the organic solvent by evaporation of the solvent leaving a dye residue, cooling and precipitation of the dye, or extraction of the dye by contacting the dye-containing solvent solution with an aqueous solution containing a reducing agent for the dye. When dye is extracted from the dye-containing solvent solution by contacting it with an aqueous solution containing a reducing agent, the dye is subsequently insolubilized by oxidation, and the dye is recovered from the aqueous dye solution. This process is particularly advantageous for recovering indigo dye from denim scrap.Type: GrantFiled: February 2, 1998Date of Patent: November 23, 1999Assignee: American Renewable Resources LLCInventors: Robert T.
