  • Patent number: 6464730
    Abstract: 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.

  • Patent number: 6296901
    Abstract: 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.

  • Patent number: 5571288
    Abstract: In the flame-retardant treatment of fabrics, there is provided a means for increased "loading" of phosphorus compounds (up to 25% moisture is retained after impregnation and drying of the fabric). This in turn enables a phosphonium compound "add-on" of 50% to 73% (relative to the weight of the fabric) and gives a correspondingly higher degree of flame-retardant properties.

  • Patent number: 5565007
    Abstract: Modified rayon is produced by adding a modifier to a cellulose solution and spinning fibers from the solution, or by adding a modifier to an alkali cellulose solution or material, xanthating and spinning fibers by the viscose spinning process, wherein the modifier is an amine of the formula (1a), (1b), (1c), (1d) or (1e) ##STR1## The modified rayon produced in this way can be dyed with reactive dyes without addition of electrolyte salt or alkali and have significantly more affinity than conventional viscose fibers.

  • Patent number: 5542954
    Abstract: A process for the production of aminated cotton fibers by subjecting a raw cotton or cotton-polyester mixture to a modification with a saturated aliphatic compound of 3 to 15 carbon atoms which contains at least one primary, secondary, tertiary, or quaternary amino group and at least one hydrolyzable ester group, in which the saturated radical is straight chain, branched, or cyclic, and may be interrupted by one or more hetero groups and may be substituted by one or more hydroxyl groups. The modification occurs simultaneously with scouring, kiering, or dry mercerizing.

  • Patent number: 5520869
    Abstract: Regenerated cellulose fiber with a reduced tendency to fibrillation can be prepared by treating never-dried fiber with an aqueous solution or dispersion of a polymer having a plurality of cationic ionisable groups. Suitable polymers include those carrying imidazoline and azetidinium groups. The fiber may additionally be treated with an aqueous emulsion of an emulsifiable polymer.

  • Patent number: 5484457
    Abstract: Process for the continuous production of surface dyeings on cellulose fiber textile materials, characterized in that the textile materials are treated with an aqueous liquor containing at least 5 g/l of benzyl halide quaternized condensation products of precondensates of trialkanolamines and ureas, cyclic carbonates and/or epihalohydrins and/or benzyl chloride quaternized condensation products of piperazine and epichloronydrin, and 0.02 to 1 g/l of a phosphoric triester whose alcohol component has 6 to 18 carbon atoms, the textile materials thus treated are then dyed in another bath with reactive dyes in an aqueous medium and the dyes are fixed by treatment with an alkaline aqueous liquor and the dyeing finished in conventional manner. The individual cellulose fibers of the textile material are not completely penetrated by the dye but, on the contrary, exhibit ring dyeing.

  • Patent number: 5403358
    Abstract: 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.

  • Patent number: 5348557
    Abstract: 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.

  • Patent number: 5320646
    Abstract: 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.

  • Patent number: 5242463
    Abstract: 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.
