    Abstract: Methods for dyeing aramid fibers, and the dyed arimid fibers produced by these methods, which comprises a dye providing step in which a vat dye or a sulfur dye is provided to aramid fibers, a solvent treatment step in which the aramid fibers are treated by a treating solution containing a polar solvent, and after the solvent treatment step, a heat treatment step in which the aramid fibers are subjected to a heat treatment, if necessary, and having one or more dyeing operations comprising the combination of the respective steps dyeing operations. The dyeing methods can be applied to either of the para-type aramid fibers, the para-type copolymerized aramid fibers and the meta-type aramid fibers, which can be dyed to a practical color depth required for developing new applications of the aramid fibers. Colorfastness of the dyed product, in particular, colorfastness to light, is improved.

  • Patent number: 8334021
    Abstract: The present invention provides methods for reducing the level of free aldehydes in coatings for flexible substrates, such as tanned leather, and substantially aldehyde free substrates. The methods comprise applying to the substrate a composition of one or more aqueous emulsion or suspension composition of an acrylic polymer or silicon containing polymer that is made from, or contains one or more lower alkyl alcohol or degrades on storage or in use to form such an alcohol, and one or more water-insoluble to slightly water soluble aldehyde scavenger compound, followed by drying or curing the applied composition to form a coating. In addition, the methods provide enhanced aldehyde scrubbing, especially for acetaldehyde, by applying to a substrate an aqueous acrylic polymer or silicon containing polymer emulsion or suspension comprising a aldehyde scavenger compound that is substantially deprotonated, i.e. by raising the pH composition to 5.5 or higher.

  • 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.
