Abstract
Abstract Process for the continuous fixation of prints and pad-dyeings on polyester fibers and mixtures of polyester and cellulose fibers, wherein the carriers usual for the fixation of the disperse dyestuffs, are sprayed onto the fiber material, at a liquor pick-up of 5 to 50%, immediately before the fixation of the dyestuff.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
80 words
In a process for the fixation of prints and pad-dyeings with disperse dyestuffs on material of polyester fibers or mixtures of polyester and cellulose fibers with carriers consisting essentially of mixtures of polyethyleneglycol ether of β-naphthol and long-chain alkane or alkene-monocarboxylic acid esters of butanediol-(1,4)-polyglycol ethers, the improvement comprising: spraying an aqueous solution or dispersion of said carrier onto the dried, printed or padded fiber material at a liquor pick-up of 5 to 50% and immediately thereafter fixing the dyestuffs.
