    摘要: A method for dyeing fibrous material is provided. The method includes contacting a fibrous material with a dyebath comprising a mixture of a dye assistant and a dye soluble or dispersed with dye assistant in the dyebath. The dye assistant comprises a salt of a low molecular weight aromatic sulfonic acid, and can include a low molecular weight surfactant. The dye assistant of the present invention can be advantageously utilized for dyeing difficult to dye fibers such as aromatic polyamide fibers, polybenzimidazole fibers and aromatic polyimide fibers.

    摘要: 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 6.5, and an alkali solution is then applied to the fiber.
