Patent number: 5968207Abstract: 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: February 20, 1998Date of Patent: October 19, 1999Assignee: Milliken & CompanyInventor: Shulong Li

Patent number: 5944852Abstract: Improved dyeing processes for yarn and fabric materials are described. Dye pattern definition on a textile material is enhanced by treating the fabric or the fibers from which it is made with a quaternary ammonium compound and by including in the dye composition a gum which will react with the quaternary ammonium compound to form a viscous gel. The gel minimizes migration of the dye prior to fixation of the dye, and therefore pattern definition is improved. Similar improvements can be obtained when space dyeing yarn that comprises fibers that have been so treated.Type: GrantFiled: April 22, 1998Date of Patent: August 31, 1999Assignee: Solutia Inc.Inventors: Tingdong Lin, Gregory D.

Patent number: 5567206Abstract: A wood stain which is water-based, which is suitable for staining wood, and which is comprised of water; at least one dye selected from the group, consisting of azo, diazo and triarylmethane dyes; and a stabilizing agent which is effective to reduce free iron ion concentration in the stain when in contact with an autioclave composed of non-rust resistant steel during the staining process. The stabilizing agent includes at least one buffer effective to maintain the pH of the wood stain at greater than 7.0. Alternatively or additionally, the stabilizing agent includes at least one complexing agent which forms a complex with iron ions. A method for staining wood includes placing the wood into an autoclave composed of non-rust-resistant steel; submerging the wood in the wood stain; and staining the wood under pressure and temperature conditions effective therefor.Type: GrantFiled: July 31, 1995Date of Patent: October 22, 1996Assignee: A.W. Faber-Castell Unternehmensverwaltung GmbH & Co.Inventors: Axel Jankewitz, Gerhard Lugert

Patent number: 5453100Abstract: Polycarbonate materials are dyed by immersion into a mixture of dye or pigment dissolved in a solvent blend. The blend is made up of an impregnating solvent, which attacks the polycarbonate and allows impregnation of the dye or pigment, and a moderating solvent which reduces the aggressiveness of the impregnating solvent. A graded tint is provided by slowly withdrawing the immersed polycarbonate material from the mixture. Polycarbonate materials having a graded tint, especially sheets in the form of lenses and goggles, are also provided.Type: GrantFiled: June 14, 1994Date of Patent: September 26, 1995Assignee: General Electric CompanyInventor: Ronald F. Sieloff

Patent number: 5403361Abstract: A process for dyeing textile fiber materials with water-soluble dyestuffs, in particular anionic dyestuffs, and of these in particular those having a fiber-reactive group, in which the dyeing is carried out using low-electrolyte or entirely electrolyte-free and/or low-alkali or entirely alkali-free dye liquors or printing pastes and a fiber material which has been modified with a silane compound containing amino groups is used as the textile material. The fiber material is modified by applying the silane compound containing amino groups to the material in aqueous solution and subjecting the impregnated material to a heat treatment. Novel silane compounds which contain a secondary amino group and can likewise be employed for the purpose mentioned are furthermore described.Type: GrantFiled: August 12, 1993Date of Patent: April 4, 1995Assignee: Hoechst AGInventors: Andreas Schrell, Werner H. Russ, Thomas Riehm, Tilo Vaahs
