Description
Foreliggende oppfinnelse vedrorer en vannbasert trykkfarge The present invention relates to a water-based printing ink
av den art som er angitt i krav l's ingress. of the kind specified in claim l's preamble.
Syntetiske fibre har etter hvert funnet vid anvendelse,og deres betydning oker stadig. Karakteristisk for de nevnte syntetiske fibre er at de har en hydrofob overflate. Dette forårsaker vanskeligheter med å få fargestoffet bundet til fiberoverflaten, Synthetic fibers have gradually found wide application, and their importance is constantly increasing. Characteristic of the aforementioned synthetic fibers is that they have a hydrophobic surface. This causes difficulties in getting the dye bound to the fiber surface,
og dette har fort til at man har utviklet en ny fargestoff-gruppe, som populært kalles dispersjonsfarger. Dispersjons-fargene består i prinsipp av et vanlig fargestoff,som har den karakteristiske egenskap at det er lite eller overhodet ikke loslig i vann. Ved anvendelse av de nevnte fargestoffer blir disse finformalt til en meget liten kbrnstorrelse. For fiksering av fargestoffet på den hydrofobe fiber utsetter man tekstilen for en varmepåkjenning. Fiberens overflate vil derved sintres og delvis smelte, og man antar at fikseringen skjer på den måte ,at fargestoffet blir innkapslet - i- denne smeiten. and this quickly led to the development of a new group of dyes, which are popularly called dispersion dyes. In principle, the dispersion colors consist of an ordinary dye, which has the characteristic property that it is little or not at all soluble in water. When using the aforementioned dyes, these are finely ground to a very small grain size. To fix the dye on the hydrophobic fibre, the textile is subjected to a heat stress. The surface of the fiber will thereby be sintered and partially melt, and it is assumed that the fixation takes place in such a way that the dye is encapsulated - in - this melt.
Varmebehandlingen av tekstilen kan foretas på forskjellige The heat treatment of the textile can be carried out in different ways
måter. Tidligere var det vanlig å anvende trykkdamp. Etter hvert har man også begynt å anvende varm luft, og i dag er den mest foretrukkede metode • anvendelse av overopphetet damp, som har en temperatur pa 175-18o°C og normalt trykk. ways. In the past, it was common to use pressurized steam. Gradually, hot air has also started to be used, and today the most preferred method is • the use of superheated steam, which has a temperature of 175-18o°C and normal pressure.
Tekstilene kan trykkes ved hjelp av vanlige kjente trykkmetoder, såsom maskintfykk og filmtrykk av typen flattrykk, rotasjon The textiles can be printed using commonly known printing methods, such as machine printing and film printing of the flat printing type, rotation
samt vanlig bordtrykk. as well as ordinary desktop printing.
Av hittil konvensjonelle fortykningsmidler, som har blitt anvendt ved trykk med dipersjonsfargestoffer, kan folgende nevnes: Johannesbrddkjerneemne, guar, stivelseseter, krystall-gummi, kieselsyreholdige fortykningsmidler samt tragant. Mange av de ovennevnte fortykningsmidlene er vanskelig tilgjenglige, de er meget dyre og dessuten fåes mange tekniske ulemper ved anvendelse av disse fortykningsmidler. Den film som disse fortykningsmidler gir på overflaten blir. bl.a.spro. Dette kan forårsake at tekstilen brister. Dessuten kan fortykningsmidlet skalle av slik at fargen lokalt forsvinner, og hvorved samtidig tekstilen forurenses av avskallet fargestoff. Of the hitherto conventional thickeners, which have been used in printing with dispersion dyes, the following can be mentioned: locust bean gum, guar, starch ether, crystal gum, silicic acid-containing thickeners and tragacanth. Many of the above-mentioned thickeners are difficult to obtain, they are very expensive and, moreover, many technical disadvantages are obtained when using these thickeners. The film that these thickeners provide on the surface becomes. i.a. spro This can cause the fabric to burst. In addition, the thickener can peel off so that the color disappears locally, and at the same time the textile is contaminated by the peeling dye.

side 276 og 299 - 3o3, er det kjent at natrium-,kalium- og ammoniumalginater er velegnede fortykningsmidler for ikke-tungmetallinhholdende fargestoffer. Med hensyn til magnesiumalginat så er det i denne artikkel kun nevnt at denne forbindelse er vannopploslig, mens det er kun natrium-, kalium- pages 276 and 299 - 3o3, it is known that sodium, potassium and ammonium alginates are suitable thickeners for non-heavy metal-containing dyes. With regard to magnesium alginate, in this article it is only mentioned that this compound is water-soluble, while it is only sodium-, potassium-
og ammoniumalginatene som blir nevnt som fortykningsmidler for trykkfarger. and the ammonium alginates which are mentioned as thickeners for printing inks.
Fra US patent nr. 2.857.236 er det kjent alginatbaserte trykkfarger inneholdende diammoniumfosfat. Av dette patentskrift fremgår det at man tidligere anvendte sekvesteringsmidler for å gi trykkfargen de onskede flyteegenskaper. I henhold til patentskriftet så tilsettes alginatfortykningsmidlet ca. lo vekt-% diammoniumfosfat regnet på vekten av det vannfrie alginat. I dette patentskrifts eksempler er det kun vist anvendelse av natriumalginat, selvom det også er anfort at magnesiumalginat også kan anvendes. Imidlertid hvis magnesiumalginat tilsettes diammoniumfosfat, så vil en slik blanding i vandig opplosning resultere i utfellelse av uopploselig magnesiumfosfat og en tilsvarende del av alginatet vil således foreligge i form av ammoniumalginat. Hvis.det, som det fremgår av dette patentskriftet, er meningen at alginatopplosningen skal inneholde lo% diammoniumfosfat, må man til magnesiumalginat tilsette tilstrekkelig diammoniumfosfat inntil alt tilstedeværende magnesium er omdannet til det uopploslige magnesiumfosf at for et overskudd av diammoniumfosf at kan erholdes.-Alginat gir en smidig og elastisk film, og dette er kanskje - årsaken til at alginatet brukes til tross for at det vanlige Na-alginat er beheftet med mange mangler. Anvendelsen av Na-alginat alene gir dårlig fargeutbytte. For å forbedre fargeutbyttet må Na-alginatet anvendes sammen med en av de foran nevnte typer Alginate-based printing inks containing diammonium phosphate are known from US patent no. 2,857,236. From this patent it appears that sequestering agents were previously used to give the printing ink the desired flow properties. According to the patent document, the alginate thickener is added approx. lo weight-% diammonium phosphate calculated on the weight of the anhydrous alginate. In the examples of this patent, only the use of sodium alginate is shown, although it is also stated that magnesium alginate can also be used. However, if magnesium alginate is added to diammonium phosphate, such a mixture in aqueous solution will result in precipitation of insoluble magnesium phosphate and a corresponding part of the alginate will thus be present in the form of ammonium alginate. If, as appears from this patent document, it is intended that the alginate solution should contain 10% diammonium phosphate, sufficient diammonium phosphate must be added to the magnesium alginate until all the magnesium present is converted to the insoluble magnesium phosphate so that an excess of diammonium phosphate can be obtained.-Alginate gives a supple and elastic film, and this is perhaps - the reason why the alginate is used despite the fact that the usual Na-alginate is affected by many shortcomings. The use of Na-alginate alone gives poor color yield. To improve the color yield, the Na-alginate must be used together with one of the types mentioned above
av fortykningsmidler, og da fortrinnsvis sammen med stivelseseter. of thickeners, and then preferably together with starch esters.
Trykkskarpheten med Na-alginat er dårlig for de hoyviskose Na-alginattyper, og man må således anvende spesielt lavviskose Na-alginatkvaliteter, hvorved man anvender en stamkonsentrasjon på ca. lo%. Dette bevirker selvfolgelig at også en alginatpasta blir dyr. The print sharpness with Na-alginate is poor for the high-viscosity Na-alginate types, and one must therefore use particularly low-viscosity Na-alginate qualities, whereby a stock concentration of approx. lo%. This obviously means that alginate paste is also expensive.
Ved mange av de hittil nevnte trykkmetoder må man anvende et fikserhjelpemiddel, en såkalt "carrier", for å sikre fikseringen av dispersjonsfargestoffene. Fikserhjelpemidlene kan ha. forskjellige sammensetninger, men et felles karakteristisk trekk for alle er at de representerer en vesentlig forurensningskilde. Fikserhjelpemidlene vil nemlig forekomme i vaskevannet. Fikserhjelpemidlene representerer dessuten en betydelig omkostning i trykkprosessen. With many of the printing methods mentioned so far, a fixing aid, a so-called "carrier", must be used to ensure the fixation of the dispersion dyes. The fixer-uppers may have. different compositions, but a common characteristic for all is that they represent a significant source of pollution. The fixing aids will be present in the washing water. The fixing aids also represent a significant cost in the printing process.
Ved anvendelse av Mg-alginat har det nå overraskende vist seg. When using Mg-alginate, it has now surprisingly been shown.
at denne type av alginat kan benyttes alene til dispersjonsfargestoffer, og oppfinnelsen er særpreget ved det som.er angitt i krav l's karakteriserende del. Som det vil fremgå that this type of alginate can be used alone for dispersion dyes, and the invention is characterized by what is stated in the characterizing part of claim 1. As will be seen
, av det etterfolgende eksempel';. 2r-,,'Så representerer trykkfargen ifolge oppfinnelsen vesentlige fordeler, idet det oppnås en bedre fargeintensitet og ytterligere er. det nodvéndig med mindre mengder magnesiumalginat i trykkpas.taen for å oppnå den bnskede konsistens, hvorfor trykkfarger inneholdende.magnesiumalginat som det eneste fortykningsmiddel blir vesentlig billigere i bruk enn kjente trykkfarger. Som eksempler på anvendbare dispers jons-f argestof f er kan folgende nevnes: "Palanil", BASF, Tyskland, "Celliton"., BASF, Tyskland, "Perliton", BASF, Tyskland, "Foron", Sandoz AG, Sveits, "Samar.on", Hoechst AG, .Tyskland, "Resilon", Bayer. AG, Tyskland, .."Terasil", Ciba-G.eigy, Sveits, "Dispersol", ICI, England, "Latyl", DuPont, USA. s , of the following example';. 2r-,,'Then the printing ink according to the invention represents significant advantages, as a better color intensity is achieved and is further. it is necessary to use smaller amounts of magnesium alginate in the printing paste to achieve the desired consistency, which is why printing inks containing magnesium alginate as the only thickener are significantly cheaper to use than known printing inks. As examples of usable dispersing agents, the following can be mentioned: "Palanil", BASF, Germany, "Celliton"., BASF, Germany, "Perliton", BASF, Germany, "Foron", Sandoz AG, Switzerland, " Samar.on", Hoechst AG, .Germany, "Resilon", Bayer. AG, Germany, .."Terasil", Ciba-G.eigy, Switzerland, "Dispersol", ICI, England, "Latyl", DuPont, USA. pp
Med Mg-alginat får man en smidig film, bedre trykkskarphet ^åvel som bedre egalitet enn det hittil har oppnådd med kjente fortykningsmidler og kombinasjoner av disse. Det har dessuten overraskende vist seg at tilsetning av fikser- - hjelpemidler helt kan utelukkes når Mg-alginat bényttes som fortykningsmiddel. Videre hår det også overraskende vist seg at Mg-alginat sammenlignet med Na-alginat er mindre omfindtlig overfor hardt vann, slik at tilsetning av sekvesteringsmidler kan sloyfes. With Mg-alginate, you get a flexible film, better print sharpness ^as well as better equality than has been achieved so far with known thickeners and combinations thereof. It has also surprisingly been shown that the addition of fixing aids can be completely ruled out when Mg-alginate is used as a thickening agent. Furthermore, it has also surprisingly been shown that Mg-alginate compared to Na-alginate is less sensitive to hard water, so that the addition of sequestering agents can be avoided.
Alle disse fordeler oppnås dessuten ved at man kan anvende et mer hoyviskost alginat enn tidligere. Man oppnår i praksis helt tilfredsstillende resultater med et produkt som har en viskositet slik at det kan benyttes i en 6% stamlosning. All these advantages are also achieved by being able to use a more highly viscous alginate than before. In practice, completely satisfactory results are achieved with a product that has a viscosity such that it can be used in a 6% stock solution.
Det er åpenbart at den besparelse, som man herved oppnår i forhold til anvendelsen av et alginat som benyttes i lo% stamkonsentrasjon, er betydelig. Oppfinnelsen er imidlertid ikke begrenset bare-til denne alginat-viskositet, idet man selvsagt kan benytte Mg-alginat med andre viskositetsverdier. It is obvious that the saving which is thereby achieved in relation to the use of an alginate which is used in lo% stock concentration is considerable. However, the invention is not limited to this alginate viscosity, as Mg-alginate with other viscosity values can of course be used.
Ifolge oppfinnelsen har man elegant lost et annet problem According to the invention, another problem has been elegantly solved
som man har hatt i forbindelse med trykking av såkalte fiberkombinasjoner. Fiberkombinasjoner som f.eks. bomull/polyester oker stadig i anvendelse. Når denne kombinasjon skal trykkes, which has been experienced in connection with the printing of so-called fiber combinations. Fiber combinations such as e.g. cotton/polyester is constantly increasing in use. When this combination is to be pressed,
må man bruke en blanding av fargestoffer. Ved trykking av slike fiberkombinasjoner har f.eks. bomullsandelen blitt trykket på a mixture of dyes must be used. When printing such fiber combinations, e.g. the cotton proportion has been pressed on
konvensjonell måte med f.eks. et reaktivfargestoff, mens polyester har blitt trykket med et dispersjonsfargestoff. Imidlertid er det svært uheldig for reaktivfargestoff-andelen conventional way with e.g. a reactive dye, while polyester has been printed with a dispersion dye. However, it is very unfortunate for the reactive dye share
at et stivelsesprodukt er nærværende, da dette stivelsesprodukt også vil reagere med fargestoffet. Utvaskingen av stivelse vil derved forhindres, og resultatet er at man får en tekstil med et hardt grep. Hvis man på den annen side ikke anvender stivelse, så blir fargeutbyttet på polyester-andelen dårlig. Ved å anvende trykkfargen ifolge oppfinnelsen hår man lost disse problemer, idet Mg-alginatet kan anvendes alene. Mg-alginat vil overfor reaktivfargestoffer oppfore seg som et vanlig alginat. Samtidig oppnår man dessuten fordelen med fullt fargeutbytte, egalitet og trykkskarphet på polyestéråndeIen.; that a starch product is present, as this starch product will also react with the dye. The leaching of starch will thereby be prevented, and the result is that you get a textile with a hard grip. If, on the other hand, starch is not used, the color yield on the polyester portion will be poor. By using the printing ink according to the invention, these problems have been solved, since the Mg-alginate can be used alone. Mg-alginate will behave like a normal alginate towards reactive dyes. At the same time, one also achieves the advantage of full color yield, equality and print sharpness on the polyester strip.;

Eksempel 2 Example 2
For å underbygge de tekniske fremskritt som erholdes ved trykkfargen i henhold til foreliggende oppfinnelse ble det utfort sammenlignende provetrykk, hvor magnesiumalginat er sammenlignet med konvensjonelle fortykningsmidler for trykk med dispersjonsfarger idet magnesiumalginat er sammenlignet med natriumalginat og Johannesbrodkjernemelbasert fortykningsmiddel. In order to substantiate the technical advances obtained with the printing ink according to the present invention, comparative test prints were carried out, where magnesium alginate is compared with conventional thickeners for printing with dispersion colors, magnesium alginate being compared with sodium alginate and locust bean gum-based thickeners.
De oppnådde fordeler ved anvendelse av et Mg-alginat er mest markante ved hoytemperatur-fiksering av fargestoffene, og i det foreliggende forsok ble to meget ofte anvendte metoder benyttet, e.g. hoytemperatur i 6 minutter ved 175°C og varmluft i 1 minutt ved 2oo°C. The advantages achieved by using a Mg-alginate are most marked in the case of high-temperature fixation of the dyes, and in the present trial two very commonly used methods were used, e.g. high temperature for 6 minutes at 175°C and hot air for 1 minute at 2oo°C.
Trykkpastaene ble fremstilt etter folgende resept: The printing pastes were produced according to the following recipe:
Pastaene ble justert med sitronsyre til pH = 5,o The pastes were adjusted with citric acid to pH = 5.0
Fargepastaene hadde en viskositet på ca. 3ooo cP. The color pastes had a viscosity of approx. 3ooo cP.
Trykkprdvene ble utfort ved bordtrykk. The printing tests were carried out by bench press.
Ved sammenlikning av de erholdte trykkprbver kunne man observere de bedre fargeintensiteter for proven inneholdende Mg-alginat. Det ble ved dette forsoket kun anvendt 24 g/kg fargepasta av Mg-alginat, mens man for de konvensjonelle fortykninger måtte anvende minimum 60 g/kg for å oppnå den onskede konsistens på trykkpastaen. Mg-ralginat blir derfor vesentlig billigere i bruk.-f ^ When comparing the pressure samples obtained, one could observe the better color intensities for the sample containing Mg-alginate. In this experiment, only 24 g/kg color paste of Mg-alginate was used, while for the conventional thickenings a minimum of 60 g/kg had to be used to achieve the desired consistency of the printing paste. Mg-ralginate is therefore significantly cheaper to use.-f ^
