  • Publication number: 20090126124
    Abstract: A method for dyeing a textile substrate, in particular for dyeing a textile substrate with reactive dyes, is described in which the textile substrate is brought in contact with a dyeing liquor containing at least one dye and after a predetermined dyeing time has elapsed, the dyed textile substrate is rinsed. The at least one dye which has not been fixed by the textile substrate and is present in the dyeing liquor is destroyed by a chemical and/or physical treatment to such an extent that the dyeing liquor is largely colourless hereafter, whereby the textile substrate being rinsed with the largely decolourised liquor. A device for carrying out the method comprises a vessel for receiving the textile substrate to be dyed and a circulation system for the dyeing liquor, where a reactor through which the dyeing liquor flows is assigned to the vessel and/or the circulation system and where inside the reactor the chemical and/or the physical treatment of the liquor to be decolourised is carried out.

  • Patent number: 6719810
    Abstract: The invention provides a method for reacting a variety of protective entities to form covalent bonds with nylon, which entities can be applied directly in the dyebath with the dyes that are used to dye the nylon without blocking such dyes or interfering with their color yield. Such protective entities include stain-blockers, chlorine resist agents, fire retardants, UV absorbers, antimicrobial agents, fume fade protectors, soil-resist agents and anti-stats. According to this method, a protective entity is reacted with a moiety having the capability of forming a covalent bond with a nylon fiber to create a modified protective entity that is adapted to form a covalent bond with a nylon fiber. The modified protective entity is added to a dyebath containing one or more dyes selected from the group consisting of fiber reactive dyes, acid dyes, acid-premetalized dyes and disperse dyes. The dyebath is applied to nylon fiber at a pH within the range of about 0.5 to about 6.

  • Patent number: 6623532
    Abstract: The present invention provides a method of applying ink containing dyes to fabric composed of synthetic and cellulose fibers using an ink-jet system to print the fabric with high color shade depth and brilliancy and ink-jet printed goods obtained by the ink-jet printing method. The fabric composed of cellulose and synthetic fibers is treated with an acidic aqueous dispersion containing cellulose reactive compound, water-soluble polymer and non-water-soluble inactive organic compound with a melting point of 40° C.-150° C. and the fabric is dried before its ink-jet printing with reactive and disperse dyes.

  • Patent number: 6620211
    Abstract: In a method for dyeing textile material with one or more fiber-reactive disperse dyestuffs in a supercritical or almost critical fluid, such as CO2, which textile material is selected from the group consisting of silk, wool and cellulose, combinations thereof and combinations of one or more thereof with synthetic fibers, such as polyester and/or polyamide, the relative humidity of the fluid is in the range from 10-100% during dyeing. Textile materials which have been dyed with the aid of this method have properties which are at least equal to those of textile materials of the same type which have been dyed in the traditional manner using water-soluble dyestuffs. A device for carrying out the dyeing method is also disclosed.

  • Publication number: 20030145397
    Abstract: This invention is directed to treatments for dyed textile goods that will improve their fastness properties. More particularly, the invention is directed to certain fixatives that, when placed on the dyed textile, allow the dye to be permanently or substantially permanently affixed to the fabric. The dye-reactive fixative comprises a water-soluble or water-dispersible polymer or oligomer having reactive groups that react with a dye on a dyed web to affix the dye to the web.

  • Patent number: 6582478
    Abstract: The invention relates to a process for preparative and reactive dyeing of cellulose material. In order to shorten the process time of conventional preparing agents and continuous operation, to make superfluous neutralizing agents for removing excess peroxy compounds as well as to reduce the mechanical equipment required vis-à-vis prior art and to reduce the use of chemical agents, the cellulose material soaked with the treatment liquor is continuously dried with pulsated air at approximately the same disintegration rate as the peroxy compounds thus used. Alkali remaining in the material from pretreatment which remained in the material is used for dyefixing said material.

  • Publication number: 20030079302
    Abstract: The invention is directed to fiber-reactive polymeric dyes, which comprise a dye covalently bound to a carboxyl-containing polymer. By “fiber-reactive” is meant that the polymeric dye will form a chemical covalent bond with the fiber, textile, or web to be treated, via functional groups for binding or attachment to the fibers of the webs to be dyed. The invention also encompasses textile dye preparations comprising a solution or suspension of the fiber-reactive polymeric dye. The resulting polymeric dye preparations have improved colorfastness and retention on the textile or web fiber structure, even after a large number of washings. The textiles or webs treated with the fiber-reactive dye are also included in the invention.
