Description

SPECIFICATION Improvements in orrelatingto organic compounds The invention relates to an electrolyte-resistant carrier composition which is particularly suitable for dyeing mixed polyester/cotton goods.
According to the invention theie is provided an electrolyte-resistant carrier composition comprising a) 65to70 parts byweightofan alkyl (C14)naphthalene; b) 15to 20 parts byweightofthe condensation product of castor oil with 30 to 50 moles ethylene oxide; c) 5to 6.5 parts by weight ofthe condensation product of a fatty C1s24 acid with 5to 15 mols ethylene oxide; d) 6to7 parts byweightofthecondensation product of a fatty saturated or unsaturated C1s24alcohol with 5 to 15 mols ethylene oxide, the condensation product being at least partially carboxymethylated;; e) 5to 6 parts by weight ofsulphonated castor oil, and f) 1 .5to 2 parts byweightofan alkyl(Cs20)aryl- sulphonic acid.
Component (a) is preferably a monomethylnaphthalene, especially a mixture of 1- and 2-methylnaph- thalene such as is commercially available.
Component (b) preferably contains from 30to 35 ethylene oxide units.
The fatty acids in component (c) preferably contain from 15 to 22 carbon atoms, with oleic acid being most preferred. Component (c) preferably contains from 10 to 15 ethylene oxide units.
The fatty alcohols in component (d) preferably contain from 15 to 22 carbon atoms, with oleyl alcohol being most preferred. Component (d) preferably contains from 1 Oto 15 ethylene oxide units and is preferably fully carboxymethylated.
Suitable components (f) include alkyl C20benzene sulphonic acids and alkylCs20naphthalene sulphonic acids. Component (f) is preferably an alkyl Cs-1sbenzene sulphonic acid, with dodecylbenzene sulphonic acid being most preferred.
The composition ofthe invention may be prepared according to known methods. Preferablythe components (a) to (f) are added in the indicated order. The addition ofthevarious ingredients is carried outwith stirring and the resulting mixture is stirred until it is homogeneous.
Preferablythe composition is neutralized with an organic base, preferably an alkanolamine such as monoethanolamine, to the extentthat it has a pH-value -value from 6to 7, preferably 6.5 to 7, when it is diluted to 10% in water.
Preferablythe composition is prepared and stored in a water-free form. This can be achieved by mixing the components in anhydrousform and/or in orderto remotethetraces af water by adding to the neutralized composition a drying agent, e.g. dextrin.
The compositions according to the invention possess levelling activity in addition to their good carrier activity. Furtherthecompositions have a notable resistance to electrolytes and are therefore particular Iy suitable as carrierfor dyeing mixed polyester/cotton goods, especially according to the one-bath two-step process.
The present invention further provides a process for dyeing or printing textile substrates comprising synth etic or semi-synthetic hydrophobic, high molecular weight organic material with disperse dyes comprising employing a carrier composition as defined above.
Suitable textile substrates include cellulose triacetate and especially linear, aromatic polyesters optionally in blends with other natural or synthetic fibres, particularly cotton.
Dyeing and printing are effected in accordance with known methods. Preferablythe dyeing is carried out under normal pressure at a temperature from 90 to 108"C. The carrier composition is employed in amounts of from 2 to 15% by weight based on the substrate.
According to a preferred embodiment ofthe invention mixed polyester/cotton goods are dyed in a single bath in the presence of a carrier composition as defined above,with a mixture of reactive and disperse dyestuffs.
More preferablythe carrier composition ofthe invention is used for dying mixed polyester/cotton goods in a one-bath two-step process in accordance with known methods. Preferably the dyeing ofthe cotton fibres is effected in the first step. After addition ofthe reactive and disperse dyestuffs and the usual additives for dyeing cotton. e.g. common salt and alkaline agents, the dyebath is heated to 50-80 C and held atsuch atemperature until the reactive dyestuff is substantiallyfixed.The dyebath is then adjusted to pH 4.5 to 6, and after addition ofthe carriercomposition, the dyebath is heated to 90 to 1 08"C, preferably 94to 1 04'C, until the disperse dyestuff is substantially fixed.
It may also be advantageous to add the disperse dyestuffs notatthe beginning ofthe reactive dyeing but afterthe acidification ofthe dyebath.
Afterthe reactive dyeing the pH ofthe dyebath may be adjusted by addition of a mineral acid, for example sulphuric acid, but preferably an organic acid, particularlyformic or acetic acid, is used.
After dyeing or printing, the textile substrate is rinsed, soaped or subjected to a reductive clearing, and then dried.
Preferred reactive dyestuffs are those having a fluorochloropyrimidine, monofluorotriazine, dichlorotriazine, dichloroquinoxaline or methylsulphochloromethylpyrimidine reactive group.
Thefollowing Examples in which ail parts are by weight and ail temperatures are in degrees Centigrade illustrate the invention.
EXAMPLE 1 A mixed polyester/cotton fabric (65/35) is introduced at 30"C in a dyebath containing per 1000 parts water: 3 % C.l. Disperse Red 73 2.7% C.l. Reactive Red 159 0.3% C.I. Reactive Orange 64 2 parts of a commerciallyavailablewashing agent based on sodium dinaphthylmethane dis ulphonate and sodium tripolyphosphate 1.5 parts of a commercially available alkaline com position containing a mixture of silicate, borax and sodium hydroxide, and 60 parts sodium chloride.
The dyebath is stirred for 20 minutes at 300 then heated over 20 minutes to 55" and held at 550 for 30 minutes. Afterthe pH of the dyebath has been adjusted to pH6 with acetic acid, there is added to the dyebath at 60" 4 parts of a carrier composition consisting or 65 parts commercially available methylnaphthalene 15 parts condensate of castor oil with 32 mols ethylene oxide 5 parts condensate of oleic acid with 12 mols ethylene oxide 7 parts partially carboxymethylated condensate of oleyl alcohol with 12 mols ethylene oxide, 6 parts sulphonated castor oil, 2 parts dodecyl benzene sulphonic acid, and 1 part dextrin the composition being neutralized to pH 6.5 to 7 (when diluted to 10% in water) with monoethanolamine before the addition of dextrin.
Thetemperature ofthe dyebath is raised to 95" over 30 minutes and dyeing is carried out at 95"for 60 minutes. After rinsing and reductive clearing, an even ruby dyeing is obtained.
EXAMPLE2 A mixed polyesterlcotton fabric (65/35) is introduced at 30 in a dyebath containing the same additives as in Example 1, butwith the following dyestuffs replacing those of Example 1: 1.92% Cl. Reactive Yellow 125 0.75% C.l. Disperse Yellow 64 0.33% C.l. Disperse Orange 31 Byfollowing the same procedure as indicated in Example 1,and using the same carriercomposition, there is obtained an even dyeing.

Disperse Red 73 2 parts of a commerciallyavailablewashingagentas indicated in Example 1, and 4 parts of the carrier composition of Example 1 and adjusted to pH 5.5 with acetic acid. The temperature of the dyebath is raised to 95" over 50 minutes and dyeing is carried out at 95" for 60 minutes. After rinsing and reductive clearing, an evenly ruby dyed fabric is obtained with a good dyeing yield.
