Abstract
Abstract An improved process for dyeing or printing water-swellable cellulosic fibers and mixtures of said cellulosic fibers with synthetic fibers by contacting the fibers throughout with a dye liquor or print paste which contains, as essential ingredients, water in an amount sufficient to swell the cellulosic fibers, a water-insoluble disperse dye and a water-soluble solvent for the disperse dye such as polyethylene glycol or boric acid esters of polyethylene glycols, and heating the contacted fibers to fix the dye, the improvement comprising the addition of from 0.5 to 5% by weight, based on the dye liquor or print paste, of a condensate of an aliphatic monocarboxylic acid of from 8 to 20 carbon atoms and a primary or secondary hydroxyalkylamine of up to 6 carbon atoms, which condensate may be ethoxylated with up to 20 moles of ethylene oxide per mole of condensate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
An improved process for dyeing or printing water-swellable cellulose fibers and mixtures of said cellulosic fibers with synthetic fibers by contacting the fibers throughout with a dye liquor or a print paste which contains, as essential ingredients, water in an amount sufficient to swell the cellulosic fibers, a water-insoluble disperse dye and a solvent for the disperse dye selected from the group consisting of boric esters of polyalkylene oxides, and heating the contacted fibers to effect fixation of the dye wherein the improvement comprises adding 0.5 to 5% by weight, based on the dyeing liquor or print paste, of a condensate of an aliphatic monocarboxylic acid of from 8 to 20 carbon atoms and a primary or secondary hydroxyalkylamine of up to 6 carbon atoms, which condensate may be ethoxylated with up to 20 moles of ethylene oxide per mole of condensate.
Claim 2
Dependent Claim
142 words
An improved process for dyeing or printing water-swellable cellulose fibers and mixtures of said cellulosic fibers with synthetic fibers by contacting the fibers throughout with a dye liquor or a print paste which contains, as essential ingredients, water in an amount sufficient to swell the cellulosic fibers, a water-insoluble disperse dye and a solvent for the disperse dye selected from the group consisting of boric esters of polyalkylene oxides, and heating the contacted fibers to effect fixation of the dye wherein the improvement comprises adding 0.5 to 5% by weight, based on the dyeing liquor or print paste, of a condensate of an aliphatic monocarboxylic acid of from 8 to 20 carbon atoms and a primary or secondary hydroxyalkylamine of up to 6 carbon atoms, which condensate may be ethoxylated with up to 20 moles of ethylene oxide per mole of condensate.
Claim 3
Dependent Claim
44 words

Claim 4
Dependent Claim
69 words
An improved process as claimed in claim 1, wherein the boric acid ester is a reaction product of the alcohol with an alcohol of from 1 to 6 hydroxyl groups and from 1 to 8 carbon atoms and ethylene oxide, which reaction product contains, per hydroxyl group, from 1 to 20 ethylene oxide units, the molar ratio of the alcohol component to boric acid being from 0.5:1 to 5:1.
Claim 5
Dependent Claim
