Patent number: 6547835Abstract: Fabric blends of inherently flame resistant fibers and flame resistant cellulosic fibers that contain a flame retardant. According to the method of production of these blends, the inherently flame resistant fibers can be dyed a full shade of color without depleting the flame retardant contained in the cellulosic fibers. In addition, the potential for laundering shrinkage of the inherently flame resistant fibers of the blends is reduced regardless of whether both, one of, or neither of the inherently flame resistant fibers and the flame resistant cellulosic fibers are dyed. Dyeing and/or shrinkage prevention of these blends is conducted at temperatures below 100° C., typically approximately between 70° C. and 100° C.Type: GrantFiled: July 6, 2000Date of Patent: April 15, 2003Assignee: Southern Mills, Inc.Inventors: Clyde C.

Patent number: 6500215Abstract: A process is disclosed for treating textile materials with selected amine oxides in order to change the aesthetics and/or make the materials more receptive to dyes. In particular, the treatment causes cellulosic materials to become more cationic and thus more receptive to anionic dyes with or without stiffening. In a preferred embodiment, the process of the present invention is directed to treating fabrics containing cotton fibers but will work to a useful extent on wool, nylon and polyester. The process is carried out by contacting said fibers or fabric with selected amine oxide compositions. The amine oxide compositions can be padded onto the fabric or printed onto the fabric. If printed onto the fabric according to a particular design, the design then becomes visible on the fabric once dyed.Type: GrantFiled: July 11, 2000Date of Patent: December 31, 2002Assignee: Sybron Chemicals, Inc.Inventors: Robert B.

The cationic compounds may be applied to the fiber material before the actual dyeing or printing process or else be applied together with the dye from the same dyeing liquor or printing paste. Suitable cationic compounds are in particular polyquaternized ammonium compounds. Level dyeings are obtained on the glass fiber materials with good light fastness properties.Type: GrantFiled: June 25, 1990Date of Patent: December 24, 1991Assignees: Ciba-Geigy Corporation, Frenzelit-Werke GmbH & Co.Inventors: Klaus Fussmann, Manfred Schnabel, Ulrich Schmidt, Hans H. Bosshard, Manfred Herrmann, Othmar Frank

Patent number: 5069681Abstract: There is disclosed a process for the photochemical stabilization of dyed polyamide fibre materials, which comprises treating the dyed material with an aqueous foamed composition which contains at least a non-dyeing copper complex of bisazomethines, acylhydrazones, semicarbazones or thiosemicarbazones of aromatic aldehydes or ketones or oximes.By means of the process of this invention it is possible to prevent wastewater from being contaminated with copper-containing impurities.Type: GrantFiled: December 26, 1990Date of Patent: December 3, 1991Assignee: Ciba-Geigy CorporationInventors: Thys Bouwknegt, Claude Dietz

Patent number: 5019133Abstract: A method for dyeing polyester-containing fibers by using a disperse dye, wherein said dyeing is conducted under an alkaline condition in an aqueous medium in the presence of at least one amino acid member selected from the group consisting of an amino acid, an amino acid derivative having at least one hydrogen atom of its amino group replaced with an organic group, and an alkali metal salt of such an amino acid or amino acid derivative, in the dyeing bath, and a dyeing assistant useful for the method.Type: GrantFiled: November 17, 1989Date of Patent: May 28, 1991Assignee: Mitsubishi Kasei CorporationInventors: Kiyoshi Himeno, Kazuhisa Konishi

Patent number: 4990164Abstract: A process is described for the photochemical stabilization of undyed and dyed polyamide fibre material, and blends thereof with other fibres, using photochemically stabilizing compositions based on copper compounds of phenols, which process comprises treating the polyamide fibre material with fibre-reactive organic copper complexes of the reaction products of o-hydroxybenzoyl derivatives of the formula ##STR1## wherein R is hydrogen or C.sub.1 -C.sub.4 alkyl and the OH substituent is located in the 3-, 4- or 5-position, with aliphatic diamines or hydroxylamine. The copper complex compounds are distinguished by a high rate of exhaustion on to the polyamide fibre material, a feature which is significant in economic terms because of the low consumption of product.Type: GrantFiled: September 27, 1989Date of Patent: February 5, 1991Assignee: Ciba-Geigy CorporationInventors: Helmut Huber-Emden, Gerhard Reinert
