(74) Fuldmægtig: Ingeniørfirmaet Budde, Schou & Co (54) Fremgangsmåde til farvning af opviklede tekstilmaterialer af syntetfibre eller syntet-fiberblandinger(74) Plenipotentiary: Engineering Company Budde, Schou & Co (54) Process for dyeing wrapped textile materials of synthetic fibers or synthetic-fiber blends

Fremgangsmåder til farvning af syntetfibre ved udtrækningsfremgangsmåder under højtemperatur(HT)-betingelser har længe været kendt i talrige variationer.Methods of dyeing synthetic fibers by extraction methods under high temperature (HT) conditions have long been known in numerous variations.

Den foreliggende opfindelse angår en fremgangsmåde til farvning af opviklede tekstilmaterialer af syntetfibre eller af blan-® dinger, der indeholder sådanne syntetiske fibre, med vanduopløselige ® dispersionsfarvestoffer ved udtrækningsmetoden, ved temperaturer på J 110-145°C, ved hvilken fremgangsmåde de opviklede emner opvarmes i en tryktæt farvebeholder før farvningen og afluftes samt dernæst ^ bringes i kontakt med den i en blandingsbeholder separat til 110- Q -145°C opvarmede samlede farveflotte, som er sat under et relativt overtryk på 5-10 atm (= 4,9-9,8 bar), ved at farveflotten fra bian- 2 146450 dingsbeholderen føres over i farvebeholderen, hvorefter farvebe-handlingen føres til ende ved cirkulation af farveflotten.The present invention relates to a method of dyeing wound textile materials of synthetic fibers or of mixtures containing such synthetic fibers, with water-insoluble® dispersion dyes by the extraction method, at temperatures of J 110-145 ° C, by which process the wound articles are heated. in a pressure-tight color container prior to dyeing and deaerating and then contacting the combined color tank heated separately at 110 ° C -145 ° C, which is placed under a relative overpressure of 5-10 atm (= 4.9 ° C). 9.8 bar) by transferring the color fleet from the intermediate container into the color container, after which the color processing is terminated by circulation of the color fleet.

En sådan fremgangsmåde er beskrevet i DE-offentlig-gørelsesskrift nr. 1.785.278 og 2.203.401. Ifølge den derfra kendte teknik sker afluftningen, ved at behandlinqsbeholderen ocr tekstilmaterialet sættes under vakuum. Dette sker i den hensigt at kunne overføre den varme behandlingsflotte fra blandingsbeholderen til behandlingsbeholderen så modstandsløst og hurtigt som muligt. Da man i anlæg af en teknisk praktisk størrelse ved hjælp af vakuumpumper kun kan opnå et delvis vakuum, er der stadigvæk et resttryk tilbage, som giver en vis modstand.Such a process is disclosed in DE Publication No. 1,785,278 and 2,203,401. According to the prior art, deaeration is effected by vacuum treatment of the treatment container and the textile material. This is done in order to be able to transfer the hot treatment float from the mixing container to the treatment container as resiliently and quickly as possible. Since only a partial vacuum can be obtained in systems of a technically practical size with the help of vacuum pumps, there is still a residual pressure which gives some resistance.

Vakuum fører desuden uundgåeligt til en stærk afkøling af det samlede system som følge af luftens udvidelse eller fordampning af fugtighed, hvadenten det er fra tekstilmaterialet eller fra vedhæftende flotte. Dette er også tilfældet, når systemet (apparat og tekstilmateriale) er blevet forvarmet før evakueringen, f.eks. ved hjælp af vanddamp. Der opstår en væsentlig temperaturforskel mellem vare og flotte, hvilket giver anledning til store uegaliteter ved den hurtige kontakt.In addition, vacuum inevitably leads to a strong cooling of the overall system due to the expansion of the air or the evaporation of moisture, whether from the textile material or from the adhesive float. This is also the case when the system (apparatus and textile material) has been preheated before the evacuation, e.g. using water vapor. There is a significant difference in temperature between product and good looking, which gives rise to large irregularities in the fast contact.

Ifølge FR-patentskrift nr. 1.067.236 imødegås denne kendte fejlkilde ved en yderligere opvarmning af det våde tekstilmateriale ved hjælp af højfrekvensstrøm.According to FR Patent No. 1,067,236, this known source of error is countered by a further heating of the wet textile material by high frequency current.

Det har nu vist sig, at man kan opnå særlig egale farvninger selv med kombinationer af flere farvestoffer, der ellers er vanskelige at farve med, samt ved samtidig væsentlig farvetids-afkortelse på opviklede emner af syntetfibre eller af blandinger, der indeholder sådanne syntetiske fibre, med vanduopløselige dispersionsfarvestoffer ved en højtryks-udtrækningsmetode, som ikke lider af de ovenfor omtalte ulemper.It has now been found that even uniform dyes can be obtained even with combinations of several dyes which are otherwise difficult to dye, and at the same time substantial color-time shortening on wound articles of synthetic fibers or of mixtures containing such synthetic fibers. with water-insoluble dispersion dyes by a high-pressure extraction method which does not suffer from the disadvantages mentioned above.

Dette sker ifølge opfindelsen ved en fremgangsmåde, som er ejendommelig ved, at opvarmningen og afluftningen af de opviklede emner sker ved, at de umiddelbart før overføringen af farveflotten udsættes for en atmosfære af varm damp, som har ca. farvetemperatur, og at farveflotten via stort dimensionerede rørledninger i løbet af 3-60 sekunder ledes samtidigt såvel indefra som udefra ind i de opviklede emner imod trykket af den luftfrie atmosfære af varm damp.This is done according to the invention by a method which is characterized in that the heating and venting of the wound objects are done by exposing them immediately before the transfer of the color fleet to an atmosphere of hot steam which has approx. color temperature and that the color fleet is passed through large-dimensioned pipelines within 3-60 seconds at the same time, both internally and externally, into the wound elements against the pressure of the air-free atmosphere of hot steam.

Den udslaggivende forskel i princippet ifølge opfindelsen og den i DE-offentliggørelsesskrifter nr. 1.785.278 og 2.203.401 beskrevne teknik består i, at farvebeholderen ikke evakueres, men fyldes med mættet højtryksdamp af omtrent samme temperatur, som anvendes ved den efterfølgende farveproces, indtil temperaturen er udlignet. Farvebeholderen indeholder altså altid en atmosfære af damp. Ved den hurtige overledning af farveflotten, som ligeledes står under et højt tryk, fra blandingsbeholderen over i farvebeholderen kondenseres dampen i sidstnævnte restfrit som følge af den påførte trykforskel, hvorved der endog frigøres kondensationsvarme. Der sker altså ingen temperatursænkning, der som ovenfor beskrevet kan virke forstyrrende.The decisive difference in principle of the invention and of the technique described in DE Publication Nos. 1,785,278 and 2,203,401 is that the color container is not evacuated, but filled with saturated high pressure vapor of about the same temperature used in the subsequent color process until the temperature is equalized. The color container therefore always contains an atmosphere of steam. At the rapid transfer of the color fleet, which is also under high pressure, from the mixing vessel into the color container, the vapor in the latter residual is condensed as a result of the applied pressure difference, thereby even releasing the heat of condensation. There is thus no temperature decrease, which as described above can be disruptive.

Foruden at tekstilmaterialet i forvejen udsættes for damp til opvarmning af de opviklede emner til farvetemperatur, har det ved fremgangsmåden ifølge opfindelsen desuden vist sig at være væsentligt, at den i forvejen opvarmede flotte samtidig skydes ind i de opviklede emner både indefra og udefra, på den ene side for at opnå en ensartethed i farvningen, på den anden side for at skåne emnerne. Kun på denne måde er en isotermisk hurtigfarvning på opviklede emner af syntetiske fibre mulig med egalt farvningsresultat.In addition to the textile material already being exposed to steam to heat the wound items to color temperature, it has also been found in the method according to the invention that the pre-heated raft is simultaneously pushed into the wound items both from the inside and the outside, on the one side to achieve a uniformity in coloration, on the other hand to spare the items. Only in this way is isothermal rapid staining on wound synthetic fiber blanks possible with uniform staining result.

I modsætning hertil er det ved den kendte fremgangsmåde i forvejen givet, at den indskudte flottes strømningsretning i emnerne er indefra og udefter (som følge af det pålagte vakuum), og den sker ensidigt og forskelligt svarende til de foreliggende forskelle i viklingernes tæthed og under samtidigt ligeledes forskellig afkøling og tilsvarende nedgang i flottens farvestofindhold. Resultatet er, først og fremmest ved lyse nuancer, en uegalitet i farvningen, som ikke mere kan fjernes. Erfaringsmæssigt kan meget lyse farvetoner overhovedet ikke bruges til upåklagelig farvning ved vakuummetoden. En yderligere påviselig ulempe ved vakuumteknikken er den ukontrollerbare deformation af de opviklede emner og påvirkningen af det først og fremmest højfølsomme teksturede tekstilmateriale, som skal farves.In contrast, in the known method, it is given in advance that the flow direction of the inserted fleet in the blanks is from inside and out (due to the applied vacuum) and it occurs unilaterally and differently according to the present differences in the density of the windings and at the same time. also different cooling and corresponding decrease in the dye content of the float. The result is, first and foremost, by light shades, an inequality in the staining that can no longer be removed. Experience shows that very bright tones cannot be used at all for impeccable staining by the vacuum method. A further demonstrable disadvantage of the vacuum technique is the uncontrollable deformation of the wound items and the influence of the primarily highly sensitive textured textile material to be dyed.

De overfor omtalte ulemper undgås ved den her omhandlede fremgangsmåde. Ved i forvejen at udsætte tekstilmaterialet for damp afluftes det ikke alene, men først og fremmest opvarmes det til farvetemperaturen, hvilket sidste også gælder for apparaturet. Derved udelukkes de temperaturforskelle, som optræder ved tilledning af opvarmede farveflotter ved vakuumteknikken, og som bevirker store affinitetsforskelle, først og fremmest ved temperaturer på over 100°C. Ved den her omhandlede fremgangsmåde møder farveflotten samme temperaturbetingelser overalt og afkøles altså ikke lokalt.The disadvantages mentioned above are avoided by the method of the present invention. By exposing the textile material to steam in advance, it is not only vented, but first and foremost it is heated to the color temperature, which lastly applies to the apparatus as well. This eliminates the temperature differences that occur in the supply of heated color floats by the vacuum technique and which cause large affinity differences, primarily at temperatures above 100 ° C. In the process of the present invention, the color fleet meets the same temperature conditions everywhere and is thus not cooled locally.

4 1464504 146450

Tilfældigheder i strømningsvejene ved vakuummetoden imødegås ved den her omhandlede fremgangsmåde bevidst ved, at farve-flotten trykkes ind samtidigt både indefra og udefra, hvortil kommer, at cirkulationspumpen sættes i gang, endnu medens flotten trykkes ind i det materiale, som skal farves. De opviklede emner udsættes altså kun for strømningstrykforskelle, men ikke for den høje trykforskel mellem blandingsbeholder og vakuum. Trykket i farvebeholderen er alene bestemt af flottens temperatur. En trykforskel opstår kun som følge af en forskel i trykket i blandingsbeholderen og det damptryk, som er givet af flottens temperatur. Da denne trykforskel virker på de opviklede emner såvel indefra og udefter som den modsatte vej, behøver man altså ikke at frygte en deformation af emnerne.Coincidences in the flow paths by the vacuum method are deliberately countered by the method of the present invention by pressing the color float simultaneously at both the inside and the outside, in addition to the circulation pump being started, while the float is being pressed into the material to be dyed. Thus, the wound items are exposed only to flow pressure differences, but not to the high pressure difference between the mixing vessel and vacuum. The pressure in the color container is solely determined by the temperature of the float. A pressure difference only arises from a difference in the pressure in the mixing vessel and the vapor pressure given by the temperature of the float. As this difference in pressure acts on the wound elements both from the inside and the outside as well as the opposite way, there is no need to fear a deformation of the blanks.

Den foreliggende opfindelses princip består i, at en farveflotte anbringes i en HT-beholder med de valgte tryk- og temperaturbetingelser og derfra ved hjælp af tryk (trykdamp, trykluft, pumpetryk) ledes over i en anden autoklav, der er fyldt med damp samt med de opviklede emner af syntetfibre, f.eks. opspolede filamenter eller stykvareruller på farvebomme. Dette sker således, at man via tilsvarende stort dimensionerede rørledninger, pumper og en fordelerventil presser flotten samtidigt såvel indefra som udefra ind i de opviklede emner. På denne måde lykkes det selv ved teksturerede syntettråde at fordele flotten ensartet i det materiale, der skal farves, på ekstremt kort tid uden deformering af ruller og filamenter. Til dette kræves der tidsrum på mindre end 60 sekunder, for det meste endog mindre end 30 sekunder. Denne hurtige "indskydning" af farve-flotten opnås ved et højt pressetryk på blandingsbeholderens side (trykforskel 5-10 atm), hvilket ifølge opfindelsen.mest hensigtsmæssigt frembringes ved hjælp af trykluft. Farvebeholderen befries i forvejen for indesluttet luft med trykdamp, og varen forvarmes samtidig. Tekstilmaterialet kan være tørt eller forvasket, hvilket kan foregå i selve farvebeholderen.The principle of the present invention is that a color float is placed in an HT container with the selected pressure and temperature conditions and from there conveyed by pressure (vapor, compressed air, pump pressure) to another autoclave filled with steam and with the wound fibers of synthetic fibers, e.g. coiled filaments or piece rolls on color bars. This is done by pushing the raft simultaneously, both internally and externally, into the wound elements via similarly large dimensioned pipelines, pumps and a distributor valve. In this way, even with textured synthetic threads, the float is evenly distributed in the material to be dyed in an extremely short time without deformation of rolls and filaments. This requires time of less than 60 seconds, usually even less than 30 seconds. This rapid "push-in" of the color fleet is achieved by a high pressure on the side of the mixing vessel (pressure difference 5-10 atm), which according to the invention is most conveniently produced by compressed air. The color container is pre-frozen for trapped air with pressure vapor, and the product is preheated at the same time. The textile material can be dry or pre-washed, which can take place in the color container itself.

Farvebeholderen er tryktæt, godt isoleret og forsynet med en varmeveksler med høj kapacitet for at kunne holde farvetemperaturen konstant. Selve flotten opvarmes i blandingsbeholderen til ca. 140°C og presses derpå ind i den dampfyldte farvebe-holder. Inden for rammerne af denne proces kan farvebeholderen, for så vidt der hersker en tilsvarende forskel i trykket, også fyldes fuldstændigt ved lukket ventil, fordi den i forvejen tilstedeværende damp kondenserer med stigende tryk.The color container is pressure-proof, well insulated and equipped with a high capacity heat exchanger to keep the color temperature constant. The float itself is heated in the mixing vessel to approx. 140 ° C and then pressed into the vapor-filled color container. Within the scope of this process, the color container, insofar as there is a corresponding difference in pressure, can also be completely filled by closed valve because the vapor present in it condenses with increasing pressure.

5 1464505 146450

En særlig udførelsesform for fremgangsmåden ifølge opfindelsen er ejendommelig ved, at de opviklede emner udsættes for en mættet vanddampatmosfære, og at farvebeholderen er tilsluttet en blokerbar kondensationsledning til forøgelse af det relative overtryk, hvorved det igen er muligt at fylde farvebeholderen helt med farvestoftilberedningen ved lukket afluft-ningsventil.A particular embodiment of the process according to the invention is characterized in that the wound items are exposed to a saturated water vapor atmosphere and that the color container is connected to a blockable condensation line to increase the relative overpressure, which in turn makes it possible to completely fill the color container with the dye preparation at closed air. -ningsventil.

Efter at den samlede farveflotte befinder sig i farvebeholderen, altså efter afsluttet indskydning, pumpes farvebadet ved hjælp af en cirkulationspumpe skiftevis indefra og udefter og udefra og indefter gennem materialerullen. Den valgte farvetemperatur opretholdes samtidigt. Pra nu af sker den endelige fiksering af farvestoffet på kort tid. Ved de under disse temperaturbetingelser høje udtrækningshastigheder er det fordelagtigt at arbejde med tilstrækkelig høje transportydelser af pumpen. Over 60 liter/kg/min fremkommer der gode farveresultater. Ved farvestoffer eller farvestofkombinationer, hvormed det er vanskeligere at farve egalt, skal der arbejdes med en transportydelse på mere end 80 liter/kg/min.After the entire color float is in the color container, that is, after completion of the insertion, the dye bath is pumped alternately from the inside and the outside and from the outside and in through the material roll by means of a circulation pump. The selected color temperature is maintained at the same time. Now, the final fixation of the dye will take place in a short time. At the high extraction rates under these temperature conditions, it is advantageous to work with sufficiently high transport services of the pump. Over 60 liters / kg / min good color results are obtained. For dyes or dye combinations, which make it more difficult to color evenly, a transport performance of more than 80 liters / kg / min must be worked.

Ved det ejendommelige træk, at den samlede farveflotte føres ind i farvebeholderen med stor hastighed og ind i det mere eller mindre tørre materiale i form af opviklede emner, adskiller fremgangsmåden sig fra de hidtil gennemførte HT-farveprocesser, der sammen med deres fremgangsmådevarianter er blevet grundigt behandlet i litteraturen. Ifølge opfindelsen bringes altså f.eks. ikke kun en del af farveflotten eller en koncentreret farvestofdispersion ind i farvebeholderen, men den samlede farveflotte presses ind næsten slagagtigt. At der kan opnås egale farvninger under disse betingelser har ikke været forudseeligt, da alle dispersionsfarvestoffer har en overordentlig høj udtrækningsevne ved disse temperaturer.By the peculiar feature of introducing the entire color fleet into the color container at high speed and into the more or less dry material in the form of coiled blanks, the method differs from the hitherto color processes performed so far, which, together with their process variants, have been thoroughly addressed in the literature. Thus, according to the invention, e.g. not only a portion of the color fleet or a concentrated dye dispersion into the color container, but the overall color fleet is pressed in almost stroke. It is not foreseeable that even staining under these conditions can be achieved, as all dispersion dyes have an extremely high drawability at these temperatures.

Det kunne endvidere ikke forventes, at farvestofopløsningerne ved så høje temperaturer, trykforskelle og mulige turbulenser stadig er egnede til indtrængning i opviklede emner. Det er endvidere overraskende, at farvestofdispersionerne også ved kombination af flere dispersionsfarvestoffer forbliver stabile tinder disse skærpede apparative betingelser og ikke har tilbøjelighed til agglornerering.Furthermore, at such high temperatures, pressure differences and possible turbulences, it is not expected that the dye solutions are still suitable for penetration into wound subjects. Furthermore, it is surprising that even when combining several dispersion dyes, the dye dispersions remain stable, pinning these aggravated operative conditions and not prone to agglomeration.

Den kendsgerning, at farvestoffernes udtrækningsevne kan udnyttes fuldstændigt ved de anvendte høje temperaturer, viser sig at være en væsentlig fordel ved den her omhandlede fremgangsmåde.The fact that the extraction ability of the dyes can be fully utilized at the high temperatures used, is found to be a significant advantage of the process of the present invention.

Den beskrevne fremgangsmåde gennemføres normalt i vandigt medium. Den kan dog også uden videre anvendes til farvning ud fra organiske opløsningsmidler. I sidstnævnte tilfælde skal man selvfølgelig ved fremgangsmådebetingelserne tage hensyn til det for det pågældende opløsningsmiddel typiske kogepunkt samt dets damptryk.The process described is usually carried out in aqueous medium. However, it can also easily be used for coloring based on organic solvents. In the latter case, of course, the process conditions must take into account the boiling point typical of the particular solvent and its vapor pressure.

Som farvestoffer anvendes ifølge fremgangsmåden de gængse handelsmærker af dispersionsfarvestoffer i pulverform eller flydende præparater. Sådanne farvestoffer er beskrevet i Colour Index, 3. oplag, bind 2 under klassebetegnelsen "Disperse Dyes".As the dyes, the conventional trademarks of dispersion dyes in powder or liquid formulations are used. Such dyes are described in Color Index, 3rd edition, Volume 2 under the class designation "Disperse Dyes".

Egnede til gennemførelsen af den her omhandlede fremgangsmåde er samtlige fiberarter af syntetisk oprindelse i enhver forarbejdningsform, som kan farves ved HT-farvemetoden. Den hidtil ukendte fremgangsmåde anvendes imidlertid fortrinsvis til teksturerede fibre af polyamid- og af lineært polyestermateriale, fordi sådanne fibre er særlig tilbøjelige til at blive farvet uegalt som følge af deres termiske forbehandling ved tekstureringen.Suitable for carrying out the process of this invention are all synthetic fiber fibers in any processing form which can be stained by the HT staining method. However, the novel method is preferably used for textured fibers of polyamide and of linear polyester material because such fibers are particularly prone to being stained unevenly due to their thermal pretreatment in the texture.

Ved farvningen af polyesterfibre kræves der ingen yderligere tilsætninger udover dispergerings- og egaliseringsmidler og kemikalierne til pH-værdiindstilling. Parvebadets pH-vær dikonstans på mellem 4,5 og 5,5 gør det muligt at reproducere farvningerne med dispersionsfarvestoffer, og den opnås ved kendte, egnede puffersystemer,. Såvel tørt som vådt materiale kan behandles.In the dyeing of polyester fibers, no additional additives other than dispersants and equalizers and the chemicals for pH adjustment are required. The pH value of the steam bath between 4.5 and 5.5 allows the stains to be reproduced with dispersion dyes and is obtained by known suitable buffer systems. Both dry and wet material can be treated.
