Description

(54) UNIFORMLY DYED WATER-SWELLABLE CELLULOSE FIBERS (71) We, BASF AKTIENGESELLSCHAFT, a German Joint Stock Company of 6700 Ludwigshafen, Federal Republic of Germany, do hereby declare -the invention, for which we pray that a Patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following Statement:- The present invention relates to uniformly dyed (as hereinafter defined) waterswellable cellulose fibers which are fast to washing, dry-cleaning, sublimation and light. By the expression "uniformly dyed" as used herein to describe the cellulosic fibers we mean fibers in which the dye is homogeneously distributed in the cellulosic fibers in the dyed regions as opposed to fibers in which the dye is solely positioned on the surface of the cellulosic fibers in the dyed regions.The dye need not be distributed along the entire length of the fibers or over the entire area of fabrics composed of such fibers and printed fibers and fabrics are included within the expression if the dye is homogeneously distributed in this way in the printed regions.
According to the invention such uniformly dyed fibers are produced by contacting water-swellable cellulose fibers with water and an oxyethylene swellersolvent (as hereinafter defined) to swell the fibers and, simultaneously or subsequently whilst the fibers are still swollen, with an essentially water-insoluble dye of the formula
where A and A', which are identical or different, are alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, chlorine, bromine, phenoxy, methylphenoxy or chlorophenoxy, n and n', which are identical or different, are 0, 1, 2 or 3, and X is hydrogen or
where R is hydrogen alkoxy of 1 to 10 carbon atoms, alkoxyalkoxy of a total of 3 to 7 carbon atoms, alkyl of 1 to 10 carbon atoms (which is unsubstituted or is monosubstituted, disubstituted or trisubstituted by chlorine), phenalkyl of 7 to 9 carbon atoms, phenyl (which is unsubstituted or is substituted by chlorine, bromine, nitro, alkyl of 1 to 4 carbon atoms or alkoxy of I to 4 carbon atoms), phenoxy, phenalkoxy of 7 to 9 carbon atoms, phenoxy-alkyl (where alkyl is of 1 to 3 carbon atoms), phenoxy-alkoxy (where alkoxy is of 2 to 4 carbon atoms), alkoxycarbonyl-alkyl (where alkoxy is of 1 to 4 carbon atoms and alkyl is of 2 to 4 carbon atoms), or phenylamino (which is unsubstituted or is substituted by chlorine, bromine or alkyl of 1 to 4 carbon atoms).
Specific examples of substituents A and A', are methyl, ethyl, propyl, isopropyl, n-butyl, sec.-butyl, tert.-butyl, methoxy, ethoxy, propoxy, isopropoxy, n butoxy, isobutoxy, chlorine, bromine, phenoxy, p-methylphenoxy and pchlorophenoxy.
Specific examples of R, in addition to hydrogen, are methoxy, ethoxy, propoxy, n-butoxy, isobutoxy, pentoxy, 2-methylbutoxy-1, 3-methylbutoxy-l, hexoxy, heptoxy-l, 2-ethylhexoxy-l, nonoxy and decoxy; o5-methoxyethoxy, A- ethoxyethoxy, -propoxyethoxy, A-butoxyethoxy, ,B-isopropoxyethoxy and /3- isobutoxypropoxy; methyl, ethyl propyl, isopropyl, butyl, isobutyl, heptyl-l, heptyl3, chloromethyl, dichloromethyl, trichloromethyl, 3-chloropropyl, 2-chloroethyl and l-chloroethyl; benzyl and p-phenylethyl; phenoxymethyl and p-phenoxyethyl; methoxycarbonylethyl, methoxycarbonylpropyl and ethoxycarbonylethyl ethoxycarbonylpropyl, methoxycarbonyl-butyl, ethoxycarbonylbutyl, butoxycarbonylbutyl, butoxycarbonylpropyl and butoxycarbonylethyl; ,B- phenoxyethoxy, A-phenoxypropoxy and phenoxybutoxy; phenoxy; phenyl, 2-, 3and 4-chlorophenyl, 3- and 4-bromophenyl, 3- and 4-nitrophenyl, 2-, 3- and 4methylphenyl, 4-ethylphenyl, 4-tert.-butylphenyl, 4-n-butylphenyl, 4isopropylphenyl, 2-, 3- and 4-methoxyphenyl and 4-ethoxyphenyl; benzyloxy, A- phenylethoxy and A-phenylpropoxy; phenylamino, 4-tolylamino, 4chlorophenylamino, 4-isopropylphenylamino, 4-tert.-butylphenylamino and 4bromophenylamino.
Preferred dyes of the formula I for use in the invention are those in which A and A' are identical and are 2-, 3- or 4-methyl, 4-methoxy or 4-phenoxy and n and n' are identical and are 0 or 1. Amongst these, in turn, more particularly preferred dyes of the formula I are those in which A and A' are identical and are 2-, 3- or 4methyl, 4-methoxy or 4-phenoxy, n and n' are identical and are 0 or 1 and X is
where R is alkoxy of 1 to 10 carbon atoms, alkoxyalkoxy of a total of 3 to 7 carbon atoms, alkyl of 1 to 10 carbon atoms, alkyl of 1 to 10, especially 1 to 5, carbon atoms which is monosubstituted, disubstituted or trisubstituted by chlorine, phenyl which is unsubstituted or substituted by chlorine, bromine, alkyl of I to 4 carbon atoms or nitro, or phenylamino which is unsubstituted or substituted by chlorine, bromine or alkyl of I to 4 carbon atoms.
Especially preferred dyes of the formula I are those in which A and A' are identical and are 2-methyl or 4-phenoxy, n and n' are 0 or 1 and X is
where R is alkoxy of 1 to 4 carbon atoms, alkyl of I to 10 carbon atoms or phenyl.
Examples of such dyes are those of the formulae
where R is alkoxy of 1 to 4 carbon atoms or alkyl of I to 10 carbon atoms,
where R is alkoxy of I to 4 carbon atoms, alkyl of 1 to 10 carbon atoms or phenyl and
where R is alkoxy of I to 4 carbon atoms.
Dyes of the formula (Ib) where R is alkyl of 1 to 4 carbon atoms are preferred above all. Amongst the dyes of the formula (Ib), the 8-acetylamino, 8propionylamino, 8-butyrylamino and 8-isobutyrylamino compounds should be singled out particularly.
The dyes of the formula I can be prepared in accordance with the process described in German Laid-Open Application DOS 1,950,679, Example 5, paragraph 2, by reacting 1,8-dihydroxy-4,5-dinitroanthraquinone with an amine of the formula
in the presence of boric acid, and reducing the resulting 1,4-bis-(phenylamino)-5hydroxy-8-nitroanthraquinone to the 8-amino compound, with or without subsequent acylation.
On the basis of their structure, the dyes of the formula (I) are appropriately described as essentially insoluble disperse dyes which as a rule cannot be applied to, for example, cottdn. This is confirmed by the data in German Laid-Open Application DOS 1,950,679.
However, U.S. Patent 3,706,525 discloses a process by means of which dyes which are water-insoluble or sparingly water-insoluble can be printed onto cellulose or cellulosic textiles. The general sense of the data relating to process conditions, given in the said U.S. patent, also applies to dyeing with the dyes of the formula (I).
According to the process disclosed in that patent the water-swellable cellulosic material to be dyed is contacted with water in an amount sufficient to swell the cellulosic material, the dye and an amount sufficient to maintain swelling of the cellulose if water is removed of a solvent having the properties given below, referred to in this specification as an oxyethylene sweller-solvent, provided that at some stage during the process the interior of the swollen cellulose is contacted with a solution of the dye in the solvent or aqueous solvent. The oxyethylene swellersolvent is required to have the following properties: a) it is at least 2.5 weight percent soluble in water at 250C; b) it boils above 150"C at atmospheric pressure; c) it is a solvent for the dye at some temperature in the range from 0 to 2250C; and d) it has the formula:
where n is 0 or 1, m is a positive integer, X1 is H, C18 alkyl, C7is aralkyl or alkaryl,
X2 is -OH, -OX3, -SX3, NHX3, NX3(C1~8 alkyl), NX3(C,~1s aralkyl or alkaryl), -OCX3, -OSO2X3, -OCOX3, II II 0 0 -NH(phenyl) or NH(naphthyl), X3 is C18 alkyl, Cs 1o cycloalkyl, C71 aralkyl or alkaryl, C6aryl, C,0 aryl or furfuryl, x is the number of unsatisfied valencies in Y', Y' is X1OCH2CHOX1CH2-, -CH2CHOX1CH2-,CH2CHCH2, -CH2C(CH2OX1)3, (-CH2)2 -C(CH2OX1)2, (--CH,),CCH,OX', (-CH2)4C, CH2(CHOX1)v CH2OX', CH2(CHOX1)vCH2 or -CH2(COHX1 )vz(CH2)zCH2 y is 2, 3 or 4, and z is 0, 1, 2, 3 or 4 but no greater than y.
Essentially, therefore, the oxyethylene sweller-solvent has an oxyethylene chain (which may be substituted by methyl) present one or more times in the molecule and may thus be regarded as ethylene glycol or a derivative thereof.
Examples of solvents which may be t sed in con junction with water in producing the fibers of the invention are ethylene glycol, di-, tri- and higher polyethylene glycols (polyethylene oxides), e.g. of molecular weight about 300, and esters of such materials, e.g. carboxylic acid esters and boric acid esters.
Further, German Laid-Open Applications DOS 2,524,243 and 1,528,743 disclose other processes by means of which the fibers according to the invention may be obtained. Printing processes are preferred. In addition to cellulose fibers, blends of cellulose fibers and synthetic fibers, especially cotton and polyester, may also be dyed and printed.
The dyed fibers according to the invention have very good fastness properties, above all wet fastness, fastness to crocking, fastness to dry-cleaning and lightfastness. In the case of prints, no staining or any white ground occurs, on, for example, washing.
For dyeing and printing, the dyes of the formula (II) are advantageously converted to dye formulations which contain the dye together with a dispersant, a water-retaining agent and water, with or without one or more other assistants conventionally used in fluid formulations, e.g. disinfectants or anti-foaming agents.
The formulations are advantageously prepared by milling a suspension of from 15 to 40, preferably from 20 to 35, parts by weight of dye (I), from 4 to 10 parts by weight of dispersant, from 5 to 15 parts by weight of water-retaining agent and from 0.5 to 1.5 parts by weight of disinfectant in from 75.5 to 35.5 parts by weight of water in a stirred ball mill, a bead mill or a sand mill, until the particle size is 0.5 ,um or less. The dye dispersions thus obtained are stable on storage.
Dispersants which may be used include the anionic and non-ionic dispersants conventionally employed for the preparation of finely divided formulations of disperse dyes. Examples of anionic dispersants are ligninsulfonates, salts of phenol/formaldehyde/sodium sulfite condensation products (German Laid-Open Application DOS 2,301,638), salts of 2-napthalenesulfonic acid/formaldehyde condensation products, salts of phenolsulfonic acid/urea/formaldehyde condensation products and salts of phenosulfonic acid/urea/formaldehyde condensation products, which have been post-condensed with phenol and formaldehyde.
Preferred non-ionic dispersants are ethylene oxide adducts and propylene oxide/ethylene oxide adducts. Such dispersants are dislosed in, for example, U.S.
Patents 2,979,528 and 3,841,888.
The amount of dispersant depends on the dye and on its concentration in the dispersion. As a rule, the amount of dispersant is from 4 to 10 per cent by weight, based on the formulation.
Preferred water-retaining agents are glycols, e.g. ethylene glycol, propylene glycol, diethylene glycol and, preferably, dipropylene glycol. Their amount is in general from 5 to 15, preferably from 8 to 12, per cent by weight based on the formulation.
In the following Examples parts are by weight.
EXAMPLE I a) A print paste is prepared from 10 parts of the finely dispersed dye of the formula
used as a formulation obtained as described in c), 100 parts of polyethylene oxide of molecular weight 300 and 790 parts of a 3 per cent strength alginate thickener.
A cotton fabric is. printed with this print paste on a rotary screen printing machine and the print is dried at 1000C. It is then heated for 1 minute at 2000C by means of hot air, rinsed cold, soaked at the boil, again rinsed cold and dried. A washfast print in a clear green hue on a white ground is obtained.
If a union fabric of cotton and polyester fibers is printed in the same manner, fixed and washed, a print in which both fibers are dyed in the same hue is obtained.
b) The dye used was prepared as follows: 40 parts of l,8-dihydroxy-4,5-dinitro- anthraquinone in 200 parts of o-toluidine are heated for 2 hours at 1500C. 20 parts of boric acid are then introduced and the reaction mixture is heated for 8 hours at 160"C. After it has cooled to 600C, 400 parts of methanol are added. The mixture is stirred for 2 hours and the 1 ,4-di-o-toluidino-5-hydroxy-8-nitro-anthraq uinone which has precipitated is filtered off, washed with methanol and water, and dried.
19.2 parts of this compound in 80 parts of o-dichlorobenzene are heated at 1500C and 4 parts of hydrazine hydrate are added in the course of 30 minutes, whilst stirring. After stirring for 2 1/2 hours at 1500C, 8 parts of methyl chloroformate is added dropwise. The mixture is stirred for a further hour at from 130 to 1500C and is then cooled to 600 C, and 150 parts of methanol are added. The reaction product which has precipitated is filtered off, washed with methanol and water and dried.
12.9 parts of the dye having the above formula are obtained.
c) The dye obtained as described in b) is converted to an aqueous dye formulation as follows: 30 parts of the dye lb), 6 parts of ligninsulfonate and 10 parts of dipropylene glycol are stirred in 50 parts of water and the suspension is milled in a sand mill until the particle size is about 0.5 ,um or less. 1 part of pentachlorophenol is then added and the dye content is brought to 30 /,, (based on the formulation) by adding water. The formulation obtained is stable on storage.
EXAMPLES 2 to 58 a) Print pastes are prepared as' described under la), using aqueous formulations of the dyes specified in the Table which follows. Prints having the hues shown in the right-hand column are obtained on cotton or polyester/cotton fabrics.
b) The dyes specified in the Table which follows were prepared by the method described in Example lb) and converted to a fluid formulation by the method described in Example Ic).
