Definitions

  • Printing pastes are usually used for printing on textile materials, the viscosity of which is adjusted with the aid of a thickener.
  • the printing pastes contain either fiber-affine dyes, which dye the material to be printed in each case, or a pigment dye and additionally a binder which firmly bonds the pigments to the textile material. After the printing process, the dyes are fixed in all cases, and the printed material is washed out and dried. In order, for example, to print woolen ridges, it is necessary to feed the ridges in a spread form to the printing device so that an acceptable through-print is achieved. Nevertheless, the achievable printing leaves something to be desired.
  • the space dyeing (multicolor dyeing) of nylon carpet fibers is currently in first place after the "Knit deknit" - (knitted wind-up) procedural - ren worked.
  • yarns made of textured polyamide carpet fibers are knitted into tubes or ribbons on circular or flat knitting machines and these are first impregnated with the base color using a padder and then printed without intermediate drying.
  • Printing is primarily based on the Rouleau printing process; the pre-padded tapes can also be printed using the Vigoureux printing process. After the paint has been applied, the dyes are fixed to the goods by steaming, washed out in special washing baths and dried. After pulling on the knitting tapes or knitting tubes, the yarns are primarily processed into tufted carpets.
  • Foam formation is extremely damaging, especially on the printing units, because the foam gets into the engravings of the printing rollers instead of the printing pastes and thus causes lighter prints or a very poor printing, since it contains significantly less dye per unit volume than the foam-free printing paste.
  • the foaming can be largely suppressed by adding suitable foam dampers, but better prints and higher processing speeds are also desired here as a result of increased quality requirements for the printed material.
  • the invention has for its object to provide a method for printing voluminous textile materials with printing pastes, in which you get good prints with sharp outlines and thus also achieves an increase in space-time yield with difficult to print materials.
  • Voluminous textile materials within the meaning of the invention are to be understood as ridges, non-woven fabrics, yarn sheets, knitted hoses, terry towels and carpets.
  • the textile materials can consist of natural and / or synthetic fibers or threads or of mixtures of fibers or threads. The process is of particular importance when printing woolen rovings, polyamide carpet yarns in the form of knitted tubes or yarn sheets as well as polyamide tufted carpets.
  • the printing pastes contain either a pigment dye and additionally a binder or fiber-affine dyes which dye the material to be printed in each case, e.g. acid dyes or metal complex dyes containing sulfo groups are used when printing woolen rovings or polyamide carpet yarns, and dispersion dyes are used when printing polyester materials.
  • the printing pastes can contain the usual additives, such as pH regulators, emulsifiers, dispersants, leveling agents, fixing accelerators, foam suppressants, oxidizing agents, reducing agents and agents for high textile finishing. In the latter case, the material is printed and finished at the same time.
  • the textile material is first applied to the entire surface using the above (a) to (c) g treated flat preparations, in such a way that the voluminous textile material is completely impregnated.
  • the voluminous textile material is prepared with a synthetic thickener based on high molecular weight polycarboxylic acids. Synthetic thickeners of this type are commercially available. For example, homopolymers and copolymers of ethylenically unsaturated carboxylic acids with 3 to 5 carbon atoms are suitable.
  • polymers of acrylic acid, methacrylic acid, maleic acid, maleic anhydride, fumaric acid and itaconic acid and copolymers of the carboxylic acids mentioned with one another for example copolymers of acrylic acid with methacrylic acid in a molar ratio of 1: 1 or in a different molar ratio, and copolymers of the carboxylic acids mentioned with other copolymerizable ethylenically unsaturated monomers, such as vinyl esters, acrylic acid esters, methacrylic acid esters, ethylene, styrene, vinyl ethers and amides of ethylenically unsaturated C 3 - to C 5 -carboxylic acids.
  • the copolymers contain at least 40, preferably 75 to 99.5% by weight of an ethylenically unsaturated carboxylic acid.
  • the thickeners are high molecular weight polymers with a molecular weight of more than 200,000 and preferably more than one million. Particularly high molecular weight synthetic thickeners are obtained if the polymerization of the ethylenically unsaturated carboxylic acids is carried out in the presence of monomers which contain two ethylenically unsaturated double bonds. Examples of such monomers are butadiene, divinylbenzene, butanediol diacrylate, divinyldioxane and diallyl phthalate. These monomers make up approximately 0.05 to 5% by weight of the high molecular weight copolymers.
  • bases are, for example, sodium hydroxide solution, potassium hydroxide solution, ammonia and amines, e.g. Triethylamine, butylamine, ethanolamine, triethanolamine, hexamethylenediamine, ethylenediamine, diethylenetriamine, triethylenetetramine and mixtures of ammonia and morpholine or hexamethylenediamine and morpholine.
  • aqueous solutions of the synthetic thickeners are obtained which, at a concentration of 0.25% by weight, a temperature of 25 ° C. and a pH of 7 in accordance with DIN 53 211, measured with a Ford beaker and an outlet nozzle with a diameter of 4 mm, give an outlet time of 30 to 60 s.
  • the neutralized synthetic thickeners in preparations (a) to (c) have a pH in the range from 10 to 6, preferably 9 to 7.
  • the voluminous textile material is prepared by passing it through a bath that contains a dye in addition to a synthetic thickener based on high molecular weight polycarboxylic acids.
  • a dye in addition to a synthetic thickener based on high molecular weight polycarboxylic acids.
  • the usual aids for block staining may also be present in the bathroom, e.g. pH regulators, buffer substances and anti-migration agents.
  • the dyes used for this are used in an electrolyte-free or low-electrolyte form.
  • Preparations (a) and (b) are used in an electrolyte-free or low-electrolyte setting because electrolytes lower the viscosity of the preparation solutions thickened with synthetic thickeners.
  • the voluminous textile material is prepared with an electrolyte-containing padding liquor or an electrolyte-containing printing paste.
  • These padding liquors or printing pastes preferably contain a natural thickener and, in addition to at least one dye, one or more electrolytes, such as organic acids, alkali metal and ammonium salts or water-soluble alkaline earth metal salts of organic or inorganic acids, carboxylic acids and anionic dispersants or their alkali metal salts.
  • electrolytes such as organic acids, alkali metal and ammonium salts or water-soluble alkaline earth metal salts of organic or inorganic acids, carboxylic acids and anionic dispersants or their alkali metal salts.
  • Synthetic thickeners containing carboxyl groups can also be used here, but because of the drop in viscosity of the liquor after the addition of electrolytes, additional thickeners must then be used to increase the viscosity of the liquor.
  • the synthetic thickeners mentioned are sensitive to electrolytes. When Glauber's salt or table salt is added, the viscosity of the thickener solution drops noticeably.
  • the thickener solution can optionally contain a dye to color the textile material. Because of the sensitivity of the synthetic thickeners to electrolytes, low-electrolyte dye solutions or dye formulations are preferably used for this.
  • Process steps (a) to (c) can be carried out, for example, in a padder, as well as by slapping or knife coating.
  • the fleet intake is 60 to 150%.
  • the already neutralized or partially neutralized Ver is used thickener because this saves one operation.
  • the voluminous textile materials in preparations (a), (b) or (c), based on the dry material are loaded with 0.05 to 1% by weight, preferably 0.1 to 0.5% by weight, of solids.
  • the voluminous textile materials prepared in accordance with (a) or (b) are then, optionally after intermediate drying, printed with electrolyte-containing printing pastes which preferably contain an electrolyte-insensitive thickener.
  • the printing paste can be applied using the customary printing methods in gravure, film or spray printing.
  • Electrolyte-insensitive thickeners are, for example, tragacanth, starch ether, core meal ether, alginates, guar meal or locust bean meal ether. These substances are primarily natural products. If electrolyte-sensitive thickeners are used, the printing paste must be thickened after the addition of the electrolyte, which causes the viscosity of the printing paste to drop, by adding a thickening agent again. 1000 g of the finished printing paste contain 2 to 20, preferably 5 to 10 g of the electrolyte-insensitive thickeners.
  • the electrolyte content of the printing paste can vary within a wide range and is between 1 and 20, preferably 5 to 15 g, based on 1000 g of the finished printing paste.
  • the electrolyte content is adjusted either by adding certain substances, such as organic acids, alkali salts of organic or inorganic acids, or by anionic dispersants. Because the commercially available Dyes partly contain alkali salts of anionic dispersants, in many cases a certain electrolyte content is already set in the printing paste by adding a certain commercially available dye. In some cases, this electrolyte content is sufficient to achieve the advantages of the method according to the invention.
  • organic acids, alkali metal or ammonium salts of organic or inorganic acids e.g. using sodium acetate, sodium formate, ammonium chloride, common salt, Glauber's salt, water-soluble alkaline earth metal salts of organic or inorganic acids and sodium salts of anionic dispersants can be obtained, for example, in the condensation of phenols or naphthols with formaldehyde and sodium bisulfite.
  • Low-molecular-weight polymers of acrylic acid or methacrylic acid in partially neutralized or completely neutralized form can be used as anionic dispersants, which also behave like an electrolyte in the printing paste.
  • the polymeric dispersants have molecular weights in the range from about 500 to 10,000.
  • a condition for the use of electrolytes or anionic dispersants in the printing pastes is, of course, that these additives with the other printing paste components do not result in any precipitation. However, this question can by means of a preliminary test easily ge - be clarified.
  • Organic acids for example formic acid, acetic acid, propionic acid, glutaric acid, adipic acid, succinic acid, p-toluenesulfonic acid, sulfosuccinic acid, benzenesulfonic acid and citric acid, are of particular importance as electrolytes.
  • the pH of the electrolyte-containing printing pastes is preferably set to values ⁇ 5.5.
  • the textile materials are printed using the known printing processes. Be particularly highlighted of these printing processes, the Rouleau printing process, the Vigoureux printing and the spray printing process.
  • a wool comb was passed in an undrawn form in 35 bands side by side and 6 cm thick through an aqueous bath containing 0.5 g per liter of a solution neutralized with sodium hydroxide solution and with 0.6% divinyldioxane based on the polymer, crosslinked polyacrylic acid and 0.5 g of a copolymer neutralized with sodium hydroxide solution consisting of 50 mol.% Maleic acid and 50 mol.% Vinyl isobutyl ether, which was crosslinked with 0.8% hexamethylpiperazine, contained on the padder on 100% liquor absorption, based on the weight of the textile product, squeezed off and then printed with an electrolyte-containing printing paste of the following composition using the gravure printing process without intermediate drying:
  • a wool sliver which consisted of 32 ribbons and had a thickness of 6 cm, was passed through an aqueous bath in undrawn form, containing 2 g of a polyacrylic acid neutralized with sodium hydroxide solution and crosslinked with 0.5 divinylbenzene per liter, 2 g of one with ammonia neutralized copolymers of maleic acid and vinyl ethyl ether in a molar ratio of 1: 1, crosslinked with 0.6% hexamethylpiperazine and 10 g of a 25% liquid setting of dye II in equal parts of dimethylformamide and butyl diglycol. It was squeezed to a liquor intake of 100 based on the weight of the textile goods.
  • the goods were then printed without intermediate drying using an electrolyte-containing printing paste of the following composition using the gravure printing process: After printing, the goods are steamed for 30 minutes at 102 ° C in saturated steam, then washed and dried as usual. You get multi-colored effects with good standing and printing.
  • a knitted tube made of polyamide carpet yarns was passed through a bath on a space dye system which contained 2 g of a copolymer of 50 mol% maleic acid and 50 mol% ethylene neutralized with sodium hydroxide solution in liter water, which was mixed with 0.8 mol. % Diallyl phthalate was crosslinked, and 10 g of a low-electrolyte 20% liquid formulation of the dye CI 15 675 contained in equal parts dimethylformamide and butyl diglycol, squeezed on the pad to about 100% liquor absorption, based on the weight of the textile goods, and then without intermediate drying with a electrolytic printing paste of the following composition printed by gravure printing:
  • the voluminous textile material is steamed for 5 minutes at approx. 102 ° C with saturated steam, then washed out and dried as usual.
  • a knitted tube is obtained which, in addition to the sharp state of the prints, has an excellent through-print which is important for later patterning and is free from gray veils.
  • a polyamide tufted carpet was pre-padded with a liquor containing 0.5 g of a high molecular weight polyacrylic acid neutralized with sodium hydroxide solution and crosslinked with 0.8% divinylbenzene in the liter of water, squeezed to a liquor absorption of 80% and then thickened slightly without intermediate drying electrolyte-containing dye liquor of the following composition applied according to the pattern by the spray printing process:
  • the pH of the liquor was adjusted to 4 using acetic acid.
  • the goods were then steamed for 8 minutes at approx. 102 ° C. with saturated steam, washed out and dried.
  • a printed carpet product was obtained which was characterized by sharp contours and good through-printing down to the bottom of the fiber loops.
  • a knitted tube made of polyamide carpet yarn was passed through a bath of the following composition on a space dye system:
  • the goods were then squeezed off on the paddle to about 80% liquor absorption, based on the weight of the textile goods, and then printed without the intermediate drying using a printing paste of the following composition using the gravure printing process:
  • the goods were steamed for 6 minutes at approx. 102 ° C with saturated steam, then washed out and dried as usual.
  • a printed knitted tube was obtained which, in addition to the sharp state of the prints, had an excellent through-print which was important for later patterning, which is particularly important in the case of double-knitted polyamide carpet yarns.
  • Example 5 is repeated with the exception that no dye is used in the printing paste. This gives so-called “negative prints”, which are characterized by lightening in the printed areas.
  • a polyamide tufted carpet fabric was pre-padded with a fleet of the following composition:
  • the fleet can also be poured onto the goods using a paint applicator.
