Foreliggande uppfinning avser sat att trycka vavnader av aromatiska polyestrar av i det foljande angivet slag. The present invention relates to printing fabrics of aromatic polyesters of the following kind.

De aromatiska polyestrar, som asyftas i fiireliggande uppfinning, aro de hogpolymera estrar, som kunna erhallas genom upphettning av glykoler av serien HO (CHO n0H, dar n betecknar ett helt tal stone an 1 men icke 5verstigande 10, med tereftalsyra eller ett esterbildande derivat darav, t. ex. en alifatisk (inklusive cykloalifatisk) eller arylester eller halvester, en syrahalogen eller ett ammonium- eller aminosalt, under forhallanden, som giva estrarna i hogpolymer form. Exempel pa dylika, hogpolymera, linjara estrar aro sadana, som kunna erhallas av tereftalsyra eller ett esterbildande derivat darav samt etylenglykol, trimetylenglykol, tetrametylenglykol, hexametylenglykol och dekametylenglykol. Dessa polyestrar hava hog smaltpunkt, aro svarlOsliga och farglosa eller narmelsevis farglosa och kunna formas till tradar, vilka kunna strackas genom dragning till starka, bojliga fibrer, vilka, sasom framgar av karakteristiska rontgenmonster ha molekylar orientering i fiberaxelns langdriktning. Av dessa polyestrar foredrages polyetylentereftalat pa grand av lattheten att anskaff a densamma och pa grund av dess stora anvandbarhet sasom textilmaterial. The aromatic polyesters referred to in the present invention are the high polymeric esters which can be obtained by heating glycols of the HO (CHO nOH series, where n represents an integer of 1 but not exceeding 10, with terephthalic acid or an ester-forming derivative thereof. , for example, an aliphatic (including cycloaliphatic) or aryl ester or half ester, an acid halide or an ammonium or amino salt, under conditions which give the esters in high polymer form, Examples of such, high polymers, linear esters or such, which may be obtained from terephthalic acid or an ester-forming derivative thereof, as well as ethylene glycol, trimethylene glycol, tetramethylene glycol, hexamethylene glycol and decamethylene glycol. Characteristic X-ray patterns have molecular orientation in the longitudinal direction of the fiber axis ng. Of these polyesters, polyethylene terephthalate is preferred because of its ease of acquisition and because of its high usability as a textile material.

I allmanhet hava dessa aromatiska polyestrar ringa frandskap till fargamnen och absorbera endast med svarighet vattenhaltiga vatskor, vilket her till foljd, att det staller sig svart att pa tillfredsstallande satt trycka desamma enligt vanliga forfaranden for textiltryckning, sarskilt om polyestrarna befinna sig i starkt andriktad form. In general, these aromatic polyesters have little resemblance to the dyes and only responsibly absorb aqueous liquors, which means that it is black to print them satisfactorily according to standard textile printing procedures, especially if the polyesters are in strongly oriented form.

Man har enligt uppfinningen funnit, att aromatiska polyestrar kunna pa tillfredsstallande satt tryckas med leukosvavelsyreestrar av kypfargamnen. It has been found according to the invention that aromatic polyesters can be satisfactorily printed with leukosulfuric acid esters of the dye dyes.

Enligt foreliggande uppfinning astadkomrues ett satt att trycka aromatiska polyestrar av oven angivet slag, som bestar i att trycka sagda polyestrar med leukosvavelsyreestrar aNkypfargamnen. According to the present invention, there is provided a method of printing aromatic polyesters of the above kind, which consists in printing said polyesters with leukosulfuric acid esters and the dye dyes.

De aromatiska polyestrarna kunna tryckas i form av fibrosa vavnader, sammanhangande folier, formade foremal eller i annan, lamplig form, och de kunna helt eller delvis orient eras genom kalldragning. The aromatic polyesters can be printed in the form of fibrous webs, continuous foils, shaped shapes or in another, suitable form, and they can be fully or partially oriented by cold drawing.

Tryckningsforfarandet kan utforas pa nagot vanligt, kant satt, som anvandes for ifragavarande, speciella fargamnen, da dessa anvandas for tryckning av Hilda, fibrosa vavnader, sammanhangande loiter eller formade foremai. The printing process can be carried out in a somewhat ordinary, edge manner, which is used for the special dyes in question, as these are used for printing Hilda, fibrous fabrics, cohesive loiters or shaped objects.

Sfisom lampliga fargamnen kunna anforas t. ex. Soledon Jade Green XS, Soledon Pink FFS, Soledon Blue 2RGS, Soledon Orange RS, Soledon Golden Orange GKS, Soledon Green GS Powder, Soledon Brown GS Powder °eh Soledon Indigo LLS. If the appropriate colors can be stated e.g. Soledon Jade Green XS, Soledon Pink FFS, Soledon Blue 2RGS, Soledon Orange RS, Soledon Golden Orange GKS, Soledon Green GS Powder, Soledon Brown GS Powder ° eh Soledon Indigo LLS.

Tryckning av aromatiska polyestrar kan utfOras i narvaro av ett svallningsmedel f5r polyestern. Lampliga svallningsmedel aro f enoler, t. ex. fenol, m- kresol, m- metoxifenol, i3-naftol, och katekin, aminer, t. ex. a-naftylamin, guanidin, anilin samt vattenlosliga anilinsalter, karbonsyror, t. ex. ,3-nafto1syra, salicylsyra och metakrylsyra, ambler, t. ex. dimetylformamid, dietylformamid, dimetylacetamid, p-toluolsulfonamid och melamin, alkoholer, t. ex. benzylalkohol, ketoner, t. ex. acetofenon och cyklohexanon, nitriler, t. ex. glutarnitril, adiponitril, etylencyanhydrin och laktonitril samt andra amnen sasom nitrobensol, tetrakloretan, trikresylfosfat och tetrametylsulf on. Svallningsmedlet loses eller emulgeras lampligen i vatten eller en vattenhaltig vatska, och denna losning eller emulsion anvandes sasom en forberedningsvatska, lampligen vid forhojd temperatur, t. ex. vid 900 a 100° C. Om sa onskas, kan svallningsmedlet inarbetas i tryckpastan. De av ovannamnda material, som icke aro losliga i vatten, emulgeras lampligen med tillhjalp av exempelvis ett salt av ett fettalkoholsulfat med lang kedja. 2— — Uppfinningen askadliggores men Sr ej begransad genom foljande exempel, i vilka angivna delar ire viktsdelar. Printing of aromatic polyesters can be performed in the presence of a swelling agent for the polyester. Suitable swelling agents are phenols, e.g. phenol, m-cresol, m-methoxyphenol, β-naphthol, and catechin, amines, e.g. α-naphthylamine, guanidine, aniline and water-soluble aniline salts, carboxylic acids, e.g. , 3-naphthoic acid, salicylic acid and methacrylic acid, ambles, e.g. dimethylformamide, diethylformamide, dimethylacetamide, p-toluolsulfonamide and melamine, alcohols, e.g. benzyl alcohol, ketones, e.g. acetophenone and cyclohexanone, nitriles, e.g. glutarnitrile, adiponitrile, ethylenecyanhydrin and lactonitrile and other substances such as nitrobenzol, tetrachloroethane, tricresyl phosphate and tetramethylsulfone. The swelling agent is suitably dissolved or emulsified in water or an aqueous liquid, and this solution or emulsion is used as a preparation liquid, suitably at elevated temperature, e.g. at 900 to 100 ° C. If desired, the swelling agent can be incorporated into the pressure paste. The above-mentioned materials, which are not soluble in water, are suitably emulsified with the aid of, for example, a salt of a long-chain fatty alcohol sulphate. 2 - - The invention is claimed but is not limited by the following examples, in which the parts indicated are parts by weight.
