Det er kjent at farvning og trykking av syntetiske fibermaterialer som polyester-, celluloseacetat-, polyvinyl- It is known that dyeing and printing synthetic fiber materials such as polyester, cellulose acetate, polyvinyl

heter, spesielt når det ved farvning under 100°C skal oppnås dype farvetoner. Det er videre kjent at disse vanskelig-heter delvis lar seg unngå ved anvendelse av såkalte farve-stoffoverførere ved farveprosessen. Med farvestoffoverførere forstås kjemiske forbindelser som settes til farvebadet i findispergert eller emulgert form, eller utfelles i farvebadet i findispergert form og begunstiger opptrekning av farvestoffet på fibrene, hvorved det lar seg oppnå en betraktelig økning av farvningens eller trykkenes farvestyrke. is called, especially when dyeing below 100°C is to achieve deep color tones. It is also known that these difficulties can be partly avoided by using so-called dye transfer agents in the dyeing process. Dye transfer agents are understood to mean chemical compounds that are added to the dye bath in finely dispersed or emulsified form, or precipitated in the dye bath in finely dispersed form and favor the attraction of the dye on the fibres, whereby a considerable increase in the color strength of the dyeing or printing can be achieved.

Som slike farvestoffoverførere er det allerede As such dye transfer agents it is already

kjent tallrike forbindelser som f.eks. o- og p-fenylfenol, metylnaftaléner, difenyl, halogenerte aromater, aromatiske karboksylsyrer og deres estere, samt fenolderivater og alkoholer, ketoner og aminer. known numerous compounds such as o- and p-phenylphenol, methylnaphthalenes, diphenyl, halogenated aromatics, aromatic carboxylic acids and their esters, as well as phenol derivatives and alcohols, ketones and amines.

I praksis har imidlertid bare få forbindelser fått betydning, eksempelvis metylnaftalen. Ved anvendelse av metylnaftalen som farvestoffoverfører er det imidlertid uheldig at rester av metylnaftalen forblir på de farvede fibre og forår- In practice, however, only a few compounds have gained importance, for example methylnaphthalene. When using methylnaphthalene as a dye transfer agent, however, it is unfortunate that residues of methylnaphthalene remain on the dyed fibers and cause

Den av fibrene tilbakeholdte uheldige virkende metylnaftalehrest One of the fibers retained unpleasant-looking methyl naphthalene residues

kan i praksis bare fjernes fra fibrene ved en spesiell varmebehandling, idet det er nødvendig med temperaturer på minst 150°C og behandlingstider på minst 3 minutter. Det er selvsagt can in practice only be removed from the fibers by a special heat treatment, as temperatures of at least 150°C and treatment times of at least 3 minutes are required. Of course it is

0at den nødvendige ekstra varmebehandling fordyrer farve- eller trykkfremgangsmåten med den nødvendige- ekstra energi, ekstra apparater og ekstraarbeid, og hindrer et glatt arbeidsforløp. I noen tilfeller lar riktignok behandlingstiden ved varmebe-handlingen seg forkorte ved en økning av temperaturen. Av denne mulighet kan det imidlertid ikke alene gjøres bruk, da f.eks. ved teksturert polyestermaterial fiberegenskapene påvirkes. I mange tilfeller, som f.eks. ved farvning av muffer, 0that the necessary extra heat treatment makes the dyeing or printing process more expensive with the necessary extra energy, extra equipment and extra work, and prevents a smooth workflow. In some cases, it is true that the treatment time during the heat treatment can be shortened by increasing the temperature. However, this possibility cannot be used alone, as e.g. in the case of textured polyester material, the fiber properties are affected. In many cases, such as when dyeing sleeves,

■ii'---' ■ii'---'

er de maskinelle forutsetninger ikke tilstede for varmebehand-lingen som er nødvendig for å fjerne metylnaftalenrester. the mechanical prerequisites are not present for the heat treatment necessary to remove methylnaphthalene residues.

Av nevnte grunner forblir derfor anvendelsen av metylnaftalen som farvestoffoverfører til farvning av syntetiske fibre begrenset til bare få arbeidsområder, enskjønt metylnaftalenet forøvrig har fordelaktige egenskaper som f arv.estof f overfører, som f.eks. en fremragende farvefordyp- For the aforementioned reasons, the use of methyl naphthalene as a dye transfer agent for dyeing synthetic fibers remains limited to only a few areas of work, although methyl naphthalene otherwise has advantageous properties as a transfer agent, such as e.g. an outstanding color immersion

Det er nå funnet at den av metylnaiftalen frembragte nedsettelse av lysektheten av farvninger og'trykk kan betraktelig reduseres, uten at de forøvrig fordelaktige egenskaper som farvestoffoverfører som metylnaftalenet har påvirkes, når det istedenfor metylnaftalen som farvestoff-overfører, anvendes en nærmere definert blanding" av metylnaf talen og difenylenoksyd. It has now been found that the reduction in the light fastness of dyeings and prints caused by methyl naphthalene can be considerably reduced, without the otherwise advantageous dye transfer properties of methyl naphthalene being affected, when instead of methyl naphthalene as dye transfer agent, a more precisely defined mixture of methylnaphthalene and diphenylene oxide.

The mixture of methylnaphthalene and diphenylene oxide is dissolved in as much solvent or solvent part and that the weight ratio between solvent resp. solvent mixture and the mixture of methylnaphthalene and diphenylene oxide amounts to 4:1 to 0.5:1, preferably 2:1 to 1:1.

Spesielt stabilt vandige emulsjoner av blandingen av metylnaftalen og difenylenoksyd i farvebadet får man når det til oppløsningen av blandingen av metylnaftalen og difenylenoksyd i et organisk oppløsningsmiddel eller oppløs-ningsmiddelblanding settes en emulgator. I denne tilbered-ning er farvestoffoverførereren ifølge oppfinnelsen også uten spesielle innretninger lett emulgerbar i farvebadet, og lar seg sågar innhelle umiddelbart i farvebadet uten den for det meste nødvendige foremulgering med vann. Particularly stable aqueous emulsions of the mixture of methylnaphthalene and diphenylene oxide in the dye bath are obtained when an emulsifier is added to the solution of the mixture of methylnaphthalene and diphenylene oxide in an organic solvent or solvent mixture. In this preparation, the dye transfer agent according to the invention is also easily emulsifiable in the dye bath without special devices, and can even be poured immediately into the dye bath without the mostly necessary pre-emulsification with water.

Som emulgatorer kan anvendes, kjente produkter eller blandinger, således eksempelvis anionaktive stoffer som alkylsulfater, f.eks. Na-laurylsulfat og Na-cetylsulfat, Turkisch-rødolje, sulfonerte oljer, alkylsulfonater, alkylåryl-sulfater som alkylbenzensulfater og alkylnaftalensulfater, eller ikke-ionogene omsetningsprodukter av alkylenoksyder med alkylfenoler, alkoholer, alifatiske mettede eller umettede karboksylsyrer, fettaminer, hydroksylgruppeholdige estere av mettede eller umettede karboksylsyrer. Known products or mixtures can be used as emulsifiers, such as, for example, anion-active substances such as alkyl sulphates, e.g. Na-lauryl sulfate and Na-cetyl sulfate, Turkisch red oil, sulfonated oils, alkyl sulfonates, alkyl aryl sulfates such as alkylbenzene sulfates and alkylnaphthalene sulfates, or non-ionic reaction products of alkylene oxides with alkylphenols, alcohols, aliphatic saturated or unsaturated carboxylic acids, fatty amines, hydroxyl group-containing esters of saturated or unsaturated carboxylic acids.

Fortrinnsvis anvendes imidlertid emulgatorbland-inger som er omtalt i DOS 1.619.489 og 1.802.210. Disse emul-gatorb landinger består av omsetningsprodukter av alkylenoksyder med ennu frie hydroksylgruppeholdige estere av mettede eller umettede alifatiske. karboksylsyrer eller hydroksykarboksylsyrer med flerverdige, 2 til 6 hydroksylgruppeholdige alkoholer eller tilleiringsforbindelser av alkylenoksyder til alkylfenoler (komponent I), alkali og/eller jordalkalisalter av alkylbenzen-sulf onsyrer (komponent II) og alifatiske primære eller sekun-dære alkoholer med 3 til 6 karbonatomer (komponent III). Egnet er også omsetningsprodukter av alkalisalter av alkylbenzen-sulfonsyre med oksetylerte fettaminer som såkalte "nøytral-salter". Preferably, however, emulsifier mixtures are used which are mentioned in DOS 1,619,489 and 1,802,210. These emulsifiers consist of reaction products of alkylene oxides with still free hydroxyl group-containing esters of saturated or unsaturated aliphatics. carboxylic acids or hydroxycarboxylic acids with polyhydric alcohols containing 2 to 6 hydroxyl groups or addition compounds of alkylene oxides to alkylphenols (component I), alkali and/or alkaline earth salts of alkylbenzene sulfonic acids (component II) and aliphatic primary or secondary alcohols with 3 to 6 carbon atoms ( component III). Reaction products of alkali salts of alkylbenzene sulphonic acid with oxyethylated fatty amines as so-called "neutral salts" are also suitable.

Til trykking dispergeres blandingen ifølge oppfinnelsen i trykkpastaen. Den egentlige trykkprosess gjennom-føres deretter på kjent måte. For printing, the mixture according to the invention is dispersed in the printing paste. The actual printing process is then carried out in a known manner.

Tørkingen av farvningen eller trykket er mulig under normale tørkebetingelser, f.eks. 30 sekunder ved 150°C uten at det inntrer en påvirkning av lysektheten av farvninger og trykk, dette gjelder også ved teksturert polyestermaterial. The drying of the coloring or the print is possible under normal drying conditions, e.g. 30 seconds at 150°C without affecting the light fastness of dyes and prints, this also applies to textured polyester material.
