Patent number: 6464730Abstract: The present invention is generally directed to a process for making fabrics containing cotton fibers more aesthetically pleasing and resistant to staining by anionic dyes by derivatizing the cotton so that it exhibits a permanent anionic charge. By increasing the anionic charge of the fibers, the fibers become resistant to anionic coloring agents which may undesirably come into contact with the fibers and the fibers can absorb greater amounts of cationic softeners and biocides. Furthermore, the negative charges repel each other resulting in a fabric with greater loft and hydrophilicity. This results in greater smoothness, better hand, and more comfort. Besides being used to prevent the cross-staining of fabrics, the present invention can also be used to make carpet materials resistant to anionic staining agents.Type: GrantFiled: June 9, 2000Date of Patent: October 15, 2002Assignee: Sybron Chemicals, Inc.Inventors: Robert B.

Patent number: 6461386Abstract: Specific transfer methods and articles to impart a metal-ion based antimicrobial finish to recipient textile surfaces. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. In particular, the inventive method involves the application of a solid, inorganic antimicrobial material to a donor substrate (such as a dryer sheet), and the subsequent placement of such a substrate within a tumble drying machine containing textile fabrics and operating the machine.

Patent number: 6296901Abstract: An ink transfer sheet and method for using the same. The transfer sheet includes a backing layer, a release layer on the backing layer, and an ink receiving layer on the release layer. The ink receiving layer contains a quaternary ammonium salt thereon or impregnated therein. To use the transfer sheet, an ink containing an anionic coloring agent is applied to the ink receiving layer, preferably using thermal inkjet methods. Thereafter, the transfer sheet is positioned on a fabric substrate. Heat is applied to the sheet which causes the release layer and ink receiving layer to adhere to the substrate. The backing layer is then detached from the release layer leaving the release and ink receiving layers (with the printed image thereon) on the substrate. This process transfers the image to the fabric substrate, with the image being stabilized by interactions between the quaternary ammonium salt and anionic coloring agent.Type: GrantFiled: March 1, 2000Date of Patent: October 2, 2001Assignee: Hewlett-Packard CompanyInventors: Melissa D.

The individual cellulose fibers of the textile material are not completely penetrated by the dye but, on the contrary, exhibit ring dyeing.Type: GrantFiled: October 31, 1994Date of Patent: January 16, 1996Assignee: BASF AktiengesellschaftInventors: Joerg Schulze, Harald Schlueter, Kurt Bacher, Wolfgang Schrott, Erich Kromm

Patent number: 5403358Abstract: A color enhancing agent comprising water, urea and a quaternary ammonium compound of the Formula (1): ##STR1## wherein: R.sup.1, R.sup.2 and R.sup.3 are each independently selected from H and C.sub.1-20 -optionally substituted alkyl or alkylene;R.sup.4 is C.sub.1-20 -optionally substituted alkyl or alkylene; andX.sup.- is an anion,provided that the total number of carbon atoms in the compound of Formula (1) is more than 30. The color enhancing agent can be used in pre-treatment compositions for textile materials prior to ink jet printing with a reactive dye and improves color yields.Type: GrantFiled: September 21, 1992Date of Patent: April 4, 1995Assignee: Imperial Chemical Industries PLCInventors: Sarah O. Aston, John R. Provost

Patent number: 5348557Abstract: There is described a process for dyeing sheetlike fiber materials, in particular those made of or containing cellulose fibers, with anionic dyes, in particular those having fiber-reactive groups, which comprises applying an alkali-free and preferably low-electrolyte or completely electrolyte-free aqueous solution of the anionic dye by the inkjet printing spray technique to a fiber material which has been pretreated and modified with a compound that contains one or more primary, secondary or tertiary amino groups or quaternary ammonium groups, which amino/ammonium groups may be part of a heterocycle. There is generally no need for an aftertreatment by washing. The costly treatment of wastewaters resulting from the excess dyeing liquors otherwise obtained is eliminated. If fiber-reactive dyes are used, fixation by means of alkali is not necessary; it is generally effected by a short heat treatment.Type: GrantFiled: September 23, 1993Date of Patent: September 20, 1994Assignee: Hoechst AktiengesellschaftInventors: Andreas von der Eltz, Andreas Schrell, Werner H.

Patent number: 5320646Abstract: A process for improving the dyeability of fabrics or fibers comprising polyhydroxylzed polymers by the use of at least one compound selected from the group consisting of a compound of the formula; ##STR1## and mixtures thereof, wherein R, R', R" and R"' are lower alkyl radicals having 1 to 20 carbon atoms and X is selected from the group consisting of sulfate, sulfonate and halide. The process requires that a dry cauticized fabric be treated with a dilute solution of a lower alkyl ammonium salt so that the fabric contains less than about 50% by weight of water prior to curing.Type: GrantFiled: April 14, 1993Date of Patent: June 14, 1994Assignee: The Dow Chemical CompanyInventors: Robert T. Patton, Stephen E. Hill, Dorothy L. Roerden

Patent number: 5242463Abstract: Anionically dyeable smooth-dry crosslinked cellulose is produced by modifying cellulose-containing material with the combination of a hydroxyalkylamine or a hydroxyalkyl quaternary ammonium salt, a methylolamide crosslinking agent and one or more reactively inert glycol ether swelling agents. The reaction is typically catalyzed with salts such as zinc nitrate or magnesium chloride used either alone or in conjunction with citric acid. Types of usable anionic dyes include acid, direct, and reactive dyes. The cellulose-containing material may be in the form of fibers, threads, linters, roving, fabrics, yarns, slivers and paper.Type: GrantFiled: March 6, 1991Date of Patent: September 7, 1993Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Eugene J. Blanchard, Robert M. Reinhardt
