Abstract: PROCESS FOR DYEING FIBROUS MATERIALS MADE OF OR CONSISTING OF WOOL WITH 1:2 COMPLEX METAL COMPOUNDS OF AZO DYESTUFFS INSOLUBLE OR SPARINGLY SOLUBLE IN WATER IN WHICH PROCESS A DYEBATH IS USED THAT CONTAINS, ADDITIONALLY TO SAID DYESTUFFS AND AN ACID, AUXILARIES KNOWN AS CARRIERS, SUCH AS AROMATIC HYDROCARBONS, AROMATIC HALOHYDROCARBONS, AROMATIC CARBOXYLIC ACIDS OR ESTERS THEREOF OR PHENOL DERIVATIVES. THE ADVANTAGE OF THE PROCESS OF THE PRESENT INVENTION IS ESPECIALLY TO BE SEEN IN THE FACT THAT EASILY OBTAINABLE DYESTUFFS CAN BE USED WITH GOOD COLOR YIELD FOR THE DYEING OF WOOL.

Abstract: 1,262,960. Dyeing wool. FARBWERKE HOECHST A.G. 20 Aug., 1969 [20 Aug., 1968], No. 41526/69. Heading D1B. Wool materials are dyed with 1:2 metal complex azo dyes e.g. chromium or cobalt complexes which are insoluble or sparingly soluble in water in presence of an acid and/or acid yielding agent and an auxiliary acting as a carrier consisting of an aromatic hydrocarbon, aromatic halohydrocarbon, aromatic carboxylic acid or ester thereof or a phenol derivative or mixture of these carriers the dyeing being at the boiling temperature to 106‹C. Blends of wool and polyester fibres may be dyed with the addition of a disperse dye carriers specified are o-phenylphenol, pphenylphenol, diphenyl, o-dichlorobenzene, terephthalic acid dialkyl ester or hydroxyalkyl ether of phenol and may be used in quantities of 0.5 to 10 gms/litre of dyebath.
