Description

United States Patent 3,193,595 STEP-WISE PRUCESS FOR CQLGRING AND FEN- ISHHNG CELLULQSE MATEREALS WHEREHN A (ZATIONIC DYE-FDHNG AGENT IS EMPLGYED WITH THE RESTN FTNL SHENG AGENT Jack Frauhland Mawson, Ian Durham Rattee, and Erwin Seltzer, Manchester, England, assignors to Imperial Chemical Industries Limited, London, England, a corporation of Great Britain No Drawing. Filed May 3, 1962, Ser. No. 192,063 Claims priority, application Great Britain, May It}, 1961, 17 ,titlti/ 61 9 (Ilaims. (Cl. 8-48} This invention relates to a new colouration process. More particularly, the invention relates to a process for the finishing of cellulose textile fabrics coloured with reactive dyestuffs whereby a very high level of fixation of: dyestufi" on the fibre is combined with excellent quality of dyeing.
It is well known to dye or print cellulose textile fabrics with reactive dyestufis, and thereafter to submit the fabric to a conventional finishing treatment to obtain a creaseresistant or dimensionally stabilised coloured fabric. It has now been found that in such a process, a valuable eifect may be obtained by adding a cationic dye-fixing agent to the liquor from which the resin-finishing agent is applied. This procedure prevents unfixed dyestutr" from dissolving in the resin-finishing bath, and assists fixation so that the expensive and time-consuming washing process normally required when dyeing with reactive dyestuffs can be dispensed with between the dyeing and finishing steps, and is considerably shortened and frequently may be dispensed with entirely after the resin-curing step.
By a cationic dye-fixing agent, we mean an organic compound free from anionic water-solubilising groups such as sulphonic acid groups, but containing one or more ammonium groups, and frequently, but not always, an aliphatic chain of 6 or more carbon atoms. As examples of such compounds there may be mentioned the following classes:
(a) Compounds having an ammonium group and at least one aliphatic or cycloaliphatic residue having at least carbon atoms. Such substances are named in United Kingdom specifications Nos. 339,962, 366,918, 441,767, 443,588, 646,921 and 496,611. These substances may be applied in conjunction with a copper salt as described in United Kingdom specification No. 535,582.
(b) The condensation products of formaldehyde with dicyandiamide, or mixtures of urea and dicyandiamide in the presence of amine or ammonium salts. Such products are described in United Kingdom specifications Nos. 19783/38, 576,562 and 651,139. These products may also be applied in conjunction with a copper salt.
(c) The condensation products of aldehydes with hydroxyalkyl derivatives of amino and imino compounds, in the presence of salts of nitrogen containing inorganic or organic bases. Such products are described in United Kingdom specification No. 611,235.
(d) The water-soluble condensation products of nitrogen-containing complex copper compounds with compounds containing at least once the grouping:
and with aldehydes of low molecular Weight. Such prod nets are described and claimed in United Kingdom specification No. 736,792. 7
(e) The acid salts of the condensates of cyanamide, di-
cyandiamide N-substituted dicyandiamides, guanidine and Patented Aug. .3, 1965 N-substituted guanidines, with polyalkyleneimines. Such products are described and claimed in United Kingdom specifications Nos. 522,539, 657,753, 755,478 and 755,519.
(f) Arylene and alkylene biguanides such as those described and claimed in United Kingdom specification No. 705,833 and their polymers.
('3) The quaternary salts of polyaminoethylacrylates and other polymerised ethylenically unsaturated compounds containing primary, secondary or tertiary amino groups.
Thus according to the present invention there is provided the improvement in the process of colouring textile materials consisting wholly or partly of fibrous cellulose by application of a reactive dyestuff, thereafter applying a resin-finishing agent and thereafter baking the treated material to cure the resin, which improvement consists of adding to the aqueous liquor containing the resinfinishing agent, a cationic dye fixing agent as hereinbeiore defined.
By a reactive dyestuft we mean a water-soluble dyestun which contains a reactive halogen atom or other substituent capable of reacting with the resin or fibre so that the remainder of the dyestuff becomes attached to the resin or fibre through a covalent bond. As examples of such dyestuffs, there may be mentioned, for example, dyestufis containing s-triazinyl or pyrimidyl radicals carrying labile atoms or groups directly attached to the ring, and dyestuffs containing a beta-halogenopropionyl, betahalogenoethylsulphonyl, beta halogenoethylsulphamyl, beta-sulphatoethylsulphonyl, beta hydroxyethylsulphonyl, chloro-acetylamino, beta-(chloromethyl)-beta-sulphatoethylsulphamyl, acryloylamino, beta-(alkyland aryl-sulphonyloxy) alkyl sulphonyl, beta-acyloxyalkylsulphonyl, vinylsulphonyl, alkyl phosphite or sulphon fluoride radical.
By a labile atom or group, We means an atom or group which is bound by a covalent bond to a carbon atom of the pyrinn'dine or triazine nucleus but which readily dissociates under the influence of heat or alkalis, especially in the presence of moisture, to form an ion or an uncharged molecule. As examples of such atoms or groups, there may be mentioned, for example, bromine, or, preferably, chlorine atoms, sulphonic acid groups, thiocyano groups, negatively substituted aryloxy and arylthio groups, such as sulphophenoxy, sulphophenylthio, nitrosulphophenoxy, disulphophenoxy and sulphonaphthoxy groups, quaternary ammonium groups, groups of the formula:
Y r I wherein Y represents the group of atoms necessary to form a 5- or 6-membered heterocyclic ring which may carry substituents or form part of a fused ring system;
groups of the formula:
wherein R and R each represents the same or different aikyl, cycloalkyl, aryl or aralkyl groups, or R and R together form, together with the nitrogen atom, a 5- or 6-membered heterocyclic ring; and groups of the formula:
contain metal in complex formation. Specific examples of suitable dyestuffs are described in United Kingdom specification No. 209,723 in Examples 1 and 2, United Kingdom specification No. 298,494 in Example 1, in United Kingdom specifications Nos. 460,224, 733,471, 740,533, 775,308, 772,030, 774,925, 780,591, 781,930, 785,120, 785,222, 802,198, 805,562, 826,689 and 852,604, and 937,182 and 924,990.
There may also be used dyestuffs containing hydroxyl, amino, hydroxyalkylamino, guanyl hydrazide, semicarbazide r thiosemicarbazide groups linked to a triazine nucleus or hydroxyalkylamino groups linked to a pyrimidine nucleus or to the alkyl radical of an alkylsulphonyl, alkylsulphamyl, alkylcarbonyl or alkylcarbonamide group. Dyestuffs of these types have been described, for example in United Kingdom specification No. 209,723 in Example 1, in United States Patent No. 2,768,158 and United Kingdom specifications 904,227,
929,425 and 927,404, and the use of dyestuffs of these types has been described, for example in French Patents Nos. 1,206,833 and 1,208,532.
The dyestuif is applied to the textile material by immersion of the material in an aqueous solution of the dyestulf preferably by padding or by application of a printing paste containing .the dyestuif. The printing paste may be applied by any of the usual methods, such as by roller, block, screen or stencil. The dyestuff solution may contain other additions commonly used in the .art of dyeing with reactive dyestuffs, for example, urea,
wetting agents, such as alkali metal alkylated naphthalene sulphonates and condensates of ethylene oxide with alkylated phenols, fatty alcohols or fatty amines, migration inhibitor such as sodium chloride, sodium sulphate or sodium alginate and, usually, an acid binding agent to aid reaction with the fabric. The acid-binding agent is only necessary to achieve reaction with the fabric, and where the dyestuff is capable of reaction with the resin, there is no need to use an acid-binding agent. It is preferred to use a mild alkali, such as sodium carbonate or bicarbonate, as the acid-binding agent to minimise neutralisation of any acid or acid salt which may be used as curing catalyst in the subsequent processing.
After application of the dyestulf solution, the fabric is preferably dried at atmospheric temperature, but may also be dried at elevated temperatures for example by .treating with hot air at a temperature of between 50 to 150 C. or by treatment with steam in a steamer at a temperature of 100 to 105 C. for about 2 to 20 minutes. Before drying, fabric which has been dyed, particularly when containing viscose rayon, is advantageously allowed to stand in a moist condition for a period of time, which may be from minutes to 24 hours, preferably from 30 minutes to 2 hours, the treatment leading to improved fixation and diffusion of the dyestuif into the fibres, and hence to improved quality and appearance of dyeing.
The printing pastes containing the dyestulf may also contain the additives usually used with reactive dyestuffs such as urea, sodium, m-nitro-benzene sulphonate, wetting agents of the types indicated above and thickening agents such as sodium alginate, ethyl cellulose, starch, locust bean gum, and, preferably, oil-in-water emulsions and water-in-oil emulsions.
After application of the printing paste, the fabric is preferably dried, for example by passage over heated rollers, and may, if desired, then be baked or steamed for, for example, from 2 to minutes.
The dried textile fabric is then treated with the resinfinishing agent, for example by padding the material through an aqueous solution or suspension of the agent. The solution or suspension may contain other commonly-used additives for example curing-catalysts for for about 1 minute.
4: the resin-finishing agent, which may be acidic or alkaline as necessary, anionic and nonionic surface active agents, lubricating agents, softening agents, water repellentsand stiffening or bodying agents, as well as the cationic dyefixing agents.
As examples of resin-finishing agents which may be used, there may be mentioned acetal cellulose reactants (as defined in the Textile Research. Journal for 1959 at page 74) and, more particularly, mixtures comprising the methylol derivatives or lower alkyl ethers of methylol derivatives of monomeric or polymeric compounds containing a plurality of amino or mono substituted amino groups, said compounds being known from the art or used in practice for the formation of resins by condensation with formaldehyde. Suitable compounds include, for example monomeric nitrogen compounds such as urea, thiourea, substituted ureas and thioureas, dicyandiamide, dicyandiarnidine, biguanides, amides, carbamates, allophanates and heterocyclic compounds such as aminotriazines, urons, ureins, ureides, imidazolidones, triazones and hydantoins or mixtures of such compounds, and polymeric nitrogen compounds such as the polymeric amides made by the reaction of dibasic acids with diamines. The lower alkyl ethers of the methylol derivatives of these compounds include for example the methyl, ethyl, propyl and butyl ethers. Other resin-finishing agents which may be used are condensation products of ketones with aldehydes, in particular, CI-I O.
As examples of acid catalysts which may be used there may be mentioned salts formed from weakbases and mineral acids such as zinc chloride, ammonium sulphate and ammonium chloride, mineral acid salts of organic amines, weak acids, for example organic acids such as oxalic acids and substantially neutral substances which develop acidity on heating or steaming, such as magnesiumchloride and ammonium thiocyanate; mixtures of such catalysts may be used.
As examples of alkaline catalyst which may be used there may be mentioned sodium bicarbonate and sodium carbonate.
The aqueous solution used for application of the resinforming composition may contain between 3% and 40% and preferably between 5% and 30% of the resin-forming compositionsand between 0.1% and 5% and preferably between 0.5% and 3.0% of acid or alkali catalyst.
As examples of lubricating and softening agents which may be used, there may be mentioned, for example dispersions of natural or synthetic waxes, methylol stearamide and the quaternary ammonium salts of United Kingdom specification No. 808,265 (which in low concentration act as lubricants rather than as cationic dye-fixing agents). The amount of dye-fixing agent used can vary within wide limits, in some cases as little as 0.005 gram per litre of padding liquor being effective whilst in other cases as much as 1.5 grams per litre is required. These amounts are those at which a reasonable effect is shown and the use of higher quantities up to to grams per litre will give improved results.
The baking stage may be carried out at a wide range of temperatures, provided the temperature is sufficiently high to cure the resin. The timesof baking will depend upon the temperature used, a short period of heating, for example, about 10 seconds, being suificient at temperatures of the order of 200 C. whilst a period of about 1 to 5, usually 3, minutes is required at a temperature of about 155 C. The baking temperatures are preferably maintained at between C. and 200 C. adjusting the time to minimise thermal degradation of the cellulose.
If desired, the textile material can be given a short washing treatment, for example, a treatment in a weakly alkaline aqueous solution of soap or detergent at the 'boil This washing treatment serves the purpose of removing small amounts of unpolymerised resin-forming agent and the residual acidity caused by the acid catalyst or the decomposition products thereof.
The invention is illustrated but not limited by the following examples in which parts and percentages are by weight:
Example 1 100 parts of viscose rayon fabric are padded with a solution containing parts of the copper complex of 2- (5' sulpho-2'-hydroxyphenylazo)-6-(2",4"-dichloro-6"- s-triazinylamino)1-naphthol-3,S-disulphonic acid, 10 parts of sodium bicarbonate and 5 parts of sodium triisopropyl naphthalene sulphonate in 975 parts of Water, squeezed, maintained in a moist condition at atmospheric temperature for 1 hour and dried at 70 C. in a hot air drier.
The fabric is then padded through 1000 parts of a solution containing 400 parts of a 60% aqueous solution of a urea-formaldehyde precondensate (obtained by stirring a mixture of 1 mole of urea and 1.6 moles of formaldehyde at pH 8.5 and 20 C. for 4 /2 hours), parts of ammonium dihydrogen phosphate, parts of the condensate of dicyandiamide, formaldehyde and ammonium chloride obtained as described in Recipe 1 of United United Kingdom specification No. 808,265. The fabric 1 is then squeezed, dried on a pin stenter at 100 C. and baked at 150 C. for 3 minutes. The fabric is dyed a bluish-red shade having good fastness to severe Washing treatments and is resistant to creasing.
