Surfactant enhanced dyeing
First Claim
1. A dye bath for textile fibers selected from the group consisting of nylon, silk, wool, human hair, fur, alpaca or other animal fibers;
- fibers of polyester, polyamide, or polyolefins that have been polymerized with some portion of monomers that contain sulfonic acid groups to render them receptive to cationic dyes;
triacetate and acetate fibers;
vinyl fibers, and cellulose fibers treated so as to make them receptive to cationic dyes comprising between 10-4 and 15 percent of one or more (cationic) dyes selected from the list of basic, disperse and solvent dyes in The Color Index, Third Editionand its supplements, a sufficiency of an anionic surfactant for solubilizing and protonating said dye or dyes, and water maintained at a pH such that said dye is in protonated form.

Abstract
Cationic dyes and protonated disperse and solvent dyes are solubilized by an excess (over molar equivalence) of an anionic surfactant to form dye baths and inks for paper. These materials are suitable for the dyeing and printing of cationic dye receptive materials inclusive of silk, wool, nylon, triacetate, vinyl, and cationic dye receptive acrylic, polyester, and polyolefins with water-fast cationic and disperse or solvent dyes. Baths of the solubilized solvent and disperse dyes may be partially neutralized and are suitable for dyeing polyester and other hydrophobic fibers thus eliminating the need for forming dispersions with disperse dyes.
