(54) Spósob difúzneho farbenia dýh(54) Diffuse staining method for veneers
Vynález rieši spósob difúzneho farbenia dýh reaktívnymi farbivami.The present invention provides a method of diffuse dyeing of veneers with reactive dyes.
V súčasnej době sa farbenie dýh uskutočňuje pomocou vodných, alkoholických alebo iných organických roztokov kyslých farbív. Kyslé farbivá používané v súčasnej době pre híbkové farbenie dýh majú poměrně nízké molekulové hmotnosti, jednoduchú štruktúru a s tým súvisiace nízké stálosti, hlavně svetlostálosť. Najviac používané vodorozpustné moridlá na báze kyslých farbív sú málo vhodné pre hlbkové farbenie dýh v celej hmotě, pretože ťažko difundujú do dýh požadóvanej hrůbky, ktorá sa obyčajne pohybuje v rozsahu 0,6 až 1,2 mm a v poměrně dlhodobých procesoch híbkového difúzneho farbenia majú tieto moridlá nízku stabilitu a znehodnocujú sa. Vyfarbenie je nehomogénne a kvalita takto vyfarbených dýh nevyhovuje pre výrobu dýh s reprodukovatePnou kresbou. Pre hlbkové farbenie sa používajú aj roztoky anorganických solí, ako sú soli na báze dvojchrómanov, avšak tieto procesy majú v praxi obmedzené použitie z dóvodu toxicity týehto solí a pre súvisiace ekologické problémy.Currently, veneer dyeing is carried out with aqueous, alcoholic or other organic solutions of acid dyes. The acid dyes currently used for the veneer dyeing of veneers have a relatively low molecular weight, simple structure and the associated low stability, especially light fastness. The most widely used acid-based water-soluble stains are poorly suited for deep coloring of veneers throughout the mass, as they hardly diffuse into veneers of the desired depth, which usually ranges from 0.6 to 1.2 mm and have relatively long-lasting diffuse staining processes. stains have low stability and deteriorate. The coloring is inhomogeneous and the quality of the veneers thus colored is not suitable for the production of veneers with reproducible drawing. Solutions of inorganic salts such as dichromate-based salts are also used for deep dyeing, but these processes have in practice limited use due to the toxicity of these salts and for related environmental problems.
Vyššie uvedené nedostatky z vačšej časti odstraňuje spósob difúzneho farbenia lúpaných alebo krájaných dýh podPa vynálezu, ktorého podstatou je zahrievanie dýh pri teplote 70 až 140 °C po dobil 0,5 až ϋΧ hodin v moku reaktívnych íarbív, pričom sa farbivo fixuje na lignocelulózovú substanciu účinkom vodného roztoku anorganických solí v koncentračnom rozsahu 20 až 110 g/1, zásadami alebo účinkom pár amoniaku pri teplote 15 až 40 °C. Farbivo sa móže fixovat’ na lignocelulózovú substanciu aj po preniknutí farbiva do dýh. S výhodou sa difúzia reaktívnych farbív do dýh urýchli prídavkom 0,5 až 15 % polárných organických rozpúšťadiel s bodom varu 70 až 110 °C.The above drawbacks are largely eliminated by the method of diffuse dyeing of peeled or sliced veneers according to the invention, which consists in heating the veneers at a temperature of 70 to 140 ° C for 0.5 to ϋΧ hours in a beverage of reactive dyes, fixing the dye to the lignocellulose substance. aqueous solution of inorganic salts in a concentration range of 20 to 110 g / l, with bases or with ammonia vapors at a temperature of 15 to 40 ° C. The dye can be fixed to the lignocellulosic substance even after the dye has penetrated into the veneer. Preferably, the diffusion of reactive dyes into veneers is accelerated by the addition of 0.5 to 15% polar organic solvents having a boiling point of 70 to 110 ° C.
Tento spósob farbenia zaisťuje nízku migráciu farbiva pri sušení dýh, rovnoměrný prienik farbiva do požadovanej hlbky dýhy a kvalitně vyfarbenie dýh.This method of dyeing ensures low dye migration during drying of veneers, uniform penetration of dye to the desired veneer depth and good coloring of veneers.
Dýhy zafarbené difúznym spósobom, fixované účinkom zásad dosahujú vysokú stálost’ voči účinkom formaldehydu a organických rozpúšťadiel tým, že sa móžu vytvárať pevné vazby s hydroxylovými skupinami lignocelulózového substrátu dýh.The veneer-colored veneers fixed by the action of bases achieve high stability against the effects of formaldehyde and organic solvents by forming strong bonds with the hydroxyl groups of the lignocellulosic substrate of the veneer.
Spósob farbenia podPa vynálezu taktiež umožňuje náhradu kyslých farbív, v případe ich nedostatku, reaktívnymi farbivami, ktorých výrobu je možné mechanizovat’ a automatizovat’ vo vyššej miere ako výrobu kyslých farbív. Rovnako je možné v receptúre kyslých farbív časť farbiacej zmesi nahradit’ farbivami reaktívnymi.The dyeing process of the invention also allows the substitution of acid dyes, in the absence thereof, with reactive dyes, the production of which can be mechanized and automated to a greater extent than the production of acid dyes. Likewise, part of the dye mixture can be replaced by reactive dyes in the acid dye recipe.
Fixácia reaktívnych farbív v dýhách sa uskutočňuje priamo vo farbiacom roztoku vystavením dýh účinku anorganických solí ako sú hydro a dihydrofosforečnany, sírany, hydrosírany a halogenidy alkalických kovov alebo zásadami ako sú hydroxid amonný, sodný alebo draselný.Fixation of reactive dyes in veneers is carried out directly in the dye solution by exposing the veneers to inorganic salts such as hydro- and dihydrophosphates, sulphates, hydrosulfates and alkali metal halides or bases such as ammonium, sodium or potassium hydroxide.
Fixácia sa s výhodou móže uskutočniť po preniknutí farbiva do dýh tak, že sa zvýši koncentrácia anorganických solí alkalických kovov vo farbiacom roztoku na hodnotu 20 až 110 g/1.The fixation can preferably be carried out after penetration of the dye into the veneers by increasing the concentration of inorganic alkali metal salts in the coloring solution to a value of 20 to 110 g / l.
Fixáciu farbiva v dýhách je možné uskutočniť tiež po vybratí dýh z farbiaceho kúpePa ich zahrievaním v roztokoch anorganických solí alkalických kovov alebo vystavením dýh po vybratí z farbiaceho kúpePa účinku pár amoniaku pri teplote 15 až 40 °C. Přitom je možné zvýšit’ kvalitu vyfarbenia pridavkom 0,5 až 15 % organických rozpúšťadiel s bodom varu v rozsahu 70 až 110 °C, ako sú alifatické alkoholy alebo ketony.The dye fixation in the veneer can also be carried out after removing the veneers from the dye bath by heating them in solutions of inorganic alkali metal salts or by exposing the veneers after removal from the dye bath to ammonia vapor at a temperature of 15 to 40 ° C. In doing so, it is possible to improve the dyeing quality by adding 0.5 to 15% of organic solvents having a boiling point in the range of 70 to 110 ° C, such as aliphatic alcohols or ketones.
Tento spósob difúzneho farbenia dýh sa dá použiť pri farbení s reaktívnymi farbivami s reaktívnym systémom dichlórtriazínovým, tnonochlórtriazínovým, difluórchlórpyridínovým, vinylsulfónovým, akrylamidovým alebo na báze metylolovaného dusíka. Koncentrácia jednotlivých reaktívnych farbív pri použití jednozložkových farbív alebo farbiacich zmesi sa pohybuje v rozsahu 0,01 až 1,5 %.This method of diffuse veneer dyeing can be used in dyeing with reactive dyes with a reactive system of dichlorotriazine, noncholochlorotriazine, difluorochloropyridine, vinyl sulfone, acrylamide or methylated nitrogen. The concentration of the individual reactive dyes when using single component dyes or dye mixtures ranges from 0.01 to 1.5%.
Příklad 1Example 1
Lúpané dýhy dřeviny buk — Fagus silvatica — o hrúbke 0,8 mm s formátom 5 X 8 cm sa vložia do farbiaceho vodného roztoku reaktívneho organického farbiva s reaktivnym systémom na báze monochlórtriazínu (Reactive Yellow 3) o koncentrácii 1,0 g/1. Farbiaci roztok obsahuje 60 g/1 NaCl. Dýhy sa zahrievajú vo farbiacom roztoku pri teplote 90 °C po dobu 23 hodin, pri hydromodule 6,1 1/m2. Po vybratí z farbiaceho roztoku sa dýhy opláchnu vodou a sušia pri teplote 60 °C. Stupeň migrácie, vyjádřený ako farebný rozdiel (DIN 6174) medzi zakrytou a nezakrytou časťou vzorky pri sušení je DE m = 1,59. Dominantná vlnová dlžka odkrytej časti dýhy /max i = — 571,7 nm a zakrytej časti dýhy bola prakticky rovnaká ^max 2 571,5 nm. Blízké sú aj hodnoty exitačnej čistoty farby zakrytej (pE | = = 0,73) a nezakrytej časti dýhy (pE2 = 0,70) a jasu Y] = 26,4 a Y2 — 27,2. Hodnoty migrácie pri použití samotného reaktívneho farbiva Reactive Yellow 3: DE m = 6,53; /max j = = 579,1 nm,/max2 = 575,8 nm; pE , = = 0,57, pE 2 = 0,44; Y, = 37,9; Y2 = 41,6. Zafarbené a vysušené dýhy sú homogénne prefarbené v celej hrúbke. Po nalisovaní na rovinný dielec a brúsení zostane farebná diferencia (DIN 6174) medzi povrchovou vrstvou po zbrúsení 0,1 mm a stredom vzorky, tj. po zbrúsení 0,4 mm 4- DE = 0,8.Peeled 0.8 mm thick beech veneer - Fagus silvatica - in 5 X 8 cm format is placed in a dyeing aqueous solution of a reactive organic dye with a reactive system of 3 g / l of monochlorotriazine (Reactive Yellow 3). The staining solution contains 60 g / l NaCl. The veneers are heated in the dyeing solution at 90 ° C for 23 hours, at a hydromodule of 6.1 l / m 2 . After removal from the staining solution, the veneers are rinsed with water and dried at 60 ° C. The degree of migration, expressed as the color difference (DIN 6174) between the covered and uncovered part of the sample at drying is DE m = 1.59. The dominant wavelength of the exposed part of the veneer / max i = - 571.7 nm and the covered part of the veneer was practically the same? Max 2571.5 nm. Also, the values of the exclusion purity of the color of the covered (p E | = = 0.73) and the uncovered part of the veneer (p E 2 = 0.70) and the brightness Y] = 26.4 and Y 2 - 27.2 are close. Migration values using Reactive Yellow 3 alone: DE m = 6.53; λ max = 579.1 nm, λ max = 575.8 nm; P E = 0.57, p = 0.44 E 2; Y1 = 37.9; Y2 = 41,6. The colored and dried veneers are homogeneously colored throughout the thickness.
