METODA PREDOBDELAVE POLIESTRA ZA ZNIŽANJE IZLOČANJAPOLYESTER PRE-PROCESSING METHOD FOR REDUCING EXPOSURE
OLIGOMEROV PRI VISOKOTEMPERATURNEM KISLEM BARVANJU ZHIGH - TEMPERATURE ACID OLIGOMERS WITH
DISPERZIJSKIMI BARVILIDISPERSION DYES
Predmet izuma je metoda predobdelave poliestra za znižanje izločanja oligomerov pri visokotemperaturnem kislem barvanju z disperzijskimi is barvili in sestava predobdelovalne kopeli za poliester, ki ga želimo barvati po konvencionalnem kislem postopku v aparatih pri visokih temperaturah. Tehnični problem pri običajnem visokotemperaturnem kislem barvanju poliestra predstavljajo nižjemolekulske etilenglikoltereftalatne frakcije ali oligomeri, ki pri visoki temperaturi barvanja difundirajo iz notranjosti na površino poliestrnih vlaken in se posedajo na obarvan material, ali pa se delno dispergirajo v barvalni kopeli. Gre namreč za ravnotežni proces, ko se pri temperaturi barvanja te nižjemolekulske frakcije zaradi razlik v topnosti v polimerni talini in v barvalni kopeli izločajo iz vlaken.The subject of the invention is a method of pre-treatment of polyester to reduce the secretion of oligomers by high-temperature acid dyeing with dispersion and dye, and the composition of a pre-treatment bath for polyester, which is desired to be dyed by the conventional acid process in high-temperature apparatus. A technical problem with conventional high temperature acid dyeing of polyester is represented by lower molecular weight ethylene glycol terephthalate fractions or oligomers that diffuse from the inside to the surface of the polyester fibers and settle on the colored material, or partially disperse in the dye bath. It is an equilibrium process when, at the dyeing temperature, these lower molecular weight fractions are separated from the fibers due to differences in solubility in the polymer melt and in the dye bath.
V sklopu oligomerov se izločajo tako linearne, kot ciklične frakcije, pri čemer je najbolj nezaželena frakcija ciklični trimer. Ta se kot kristalini prah s tališčem 316 - 325° C poseda tudi na vitalne dele barvalnih aparatov. Spada med tiste oligomere, ki so v vodi netopni. Oligomeri ostajajo na blagu kot bel oprh, saj jih disperzijska barvila ne obarvajo.Both linear and cyclic fractions are secreted within the oligomers, the most undesirable fraction being the cyclic trimmer. As crystalline powder, with a melting point of 316 - 325 ° C, it also lends itself to vital parts of dyeing apparatus. It is one of those oligomers that are insoluble in water. The oligomers remain on the fabric as white powder, because they are not colored by dispersion dyes.
Odvisno od načina izdelave poliestra se pri poliestrih različnih proizvajalcev pri hidrotermičnih obdelavah izloča različna količina oligomerov. Plemenitilnice imajo zaradi tega pojava velike težave, ki so ekonomske narave. Tako pobarvan material je potrebno čistiti, pri čemer io je pogosto čiščenje blaga zamudno in nepopolno, čistiti pa je potrebno tudi barvalnike, kar predstavlja veliko izgubo obratovalnega časa. Pri predelavi poliestra se včasih izloča toliko oligomerov, da predstavlja prah tudi zdravstven problem.Depending on the manufacturing method of the polyester, different amounts of oligomers are eliminated from the polyesters of different manufacturers in hydrothermal treatments. Due to this phenomenon, breeding plants have major economic problems. Such colored material must be cleaned, with frequent cleaning of goods being time-consuming and incomplete, and dyeing, which is a major waste of operating time. When processing polyester, so many oligomers are sometimes released that dust is also a health problem.
Proizvajalci disperzijskih barvil poskušajo problem z oligomeri rešiti z 15 vpeljavo alkalnega barvanja. Pri tem pa ni na voljo zadosti alkalno obstojnih disperzijskih barvil, da bi v barvarnah lahko enostavno zamenjali že utečene barvne tone na poliestru dobljene z disperzijskimi barvili po kislem postopku s tako nepopolno paleto izbranih alkalno obstojnih barvil.The manufacturers of dispersion dyes are trying to solve the problem of oligomers by introducing 15 alkaline dyes. However, sufficient alkali-resistant dispersion dyes are not available in order to easily replace the already established color tones on the polyester obtained by dispersion dyes by acidic process with such an incomplete range of selected alkali-resistant dyes.
Metoda predobdelave poliestra za znižanje izločanja oligomerov pri 20 visokotemperaturnem kislem barvanju z disperzijskimi barvili po izumu, omogoča barvanje po utečenem kislem visokotemperaturnem barvalnem postopku tudi take poliestrne materiale iz katerih se izloča pri tem velika količina oligomerov. Metoda temelji na predobdelavi poliestrne tkanine v alkalni kopeli pH 11,5 - 12,2 pri 130 °C in sledečem trikratnem spiranju v mehki vroči vodi. Alkalno kopel pripravimo z ustrezno količino alkalije ali odgovarjajočih pufrnih zmesi. Tako predobdelan poliester je nato možno barvati z disperzijskimi barvili v kislem mediju, ne da bi pri barvanju zasledili težave povezane z oligomeri.The method of pretreatment of polyester to reduce the secretion of oligomers by 20 high-temperature acid dyeing using the dispersion dyes according to the invention, enables the dyeing of the liquid acidic high-temperature dyeing process to include such polyester materials from which a large amount of oligomers are extracted. The method is based on the pretreatment of a polyester fabric in an alkaline bath pH 11.5 - 12.2 at 130 ° C and the subsequent three times rinsing in soft hot water. The alkali bath is prepared with an appropriate amount of alkali or suitable buffer mixtures. The pre-treated polyester can then be dyed with dispersion dyes in acidic medium without detecting any problems associated with the oligomers.
V alkalni kopeli pH 11,5 - 12,2 pri 130° C se topi precejšnja količina oligomerov, površina poliestra pa se rahlo jedka, postane bolj gladka in dobi lepši lesk.In an alkaline bath of pH 11.5 - 12.2 at 130 ° C, a considerable amount of oligomers are melted and the surface of the polyester is slightly corrosive, smoother and more beautiful.
Fizikalno mehanske lastnosti se pri tem ne poslabšajo. V primerjavi z io lastnostmi po slepem alkalnem barvanju, ko se poliestrni tkanini poveča raztezek pri pretrgu po osnovi, pri tej predobdelavi poliestrne tkanine nismo zaznali bistvenih sprememb trdnosti pri pretrgu in raztezka pri pretrgu.Physically mechanical properties do not deteriorate. Compared to the io properties of blind alkaline dyeing, when the polyester fabric increases the elongation at tear at the base, no significant changes in the tear strength and tear elongation were detected in this pretreatment of the polyester fabric.
Z namenom, da bi nazorno prikazali učinek v pričujoči prijavi razložene 15 metode, podajamo naslednji primer.In order to illustrate clearly the effect in the present application of the 15 method explained, we give the following example.
PRIMER 1:EXAMPLE 1:
Uporabljena je 100 % poliestrna tkanina, ki je oprana s Teoponom K (Teol) pri 60° C in pri 40° C, ter dvakrat sprana z vodo sobne temperature.100% polyester fabric was used, which was washed with Teopon K (Teol) at 60 ° C and 40 ° C, and washed twice with room temperature water.
Po pranju je bila tkanina 45 sek. termofiksirana pri 190° C.After washing, the fabric was 45 sec. thermofixed at 190 ° C.
Tako pripravljeno tkanino smo alkalno predobdelali v laboratorijskem barvalniku Mathis JFL pri kopelnem razmerju 1:10. Za pripravo predobdelovalne kopeli smo uporabili mehko vodo. Predobdelava v kopeli z 1 g/l NaOH ( pH 12 ) je potekala 30 min. pri 130° C. Sledilo je trikratno spiranje tkanine v vreli mehki vodi. Alkalno predobdelano tkanino smo nato barvali pri 135° C v slepi kisli kopeli, ki je vsebovala : 1 ml/l Eganal PS ( Hoechst ), 2 ml/l Lubit RL ( Sybron / Tanatex ) in CH3COOH 995 100% ( J. T. Baker) do pH vrednosti kopeli pH 4,5-5. Barvanje je potekalo po barvalnem diagramu, ki ga priporoča firma DyStar za barvanje z Dianix AD barvili. Po barvanju smo tkanino štirikrat spirali v 40° C topli mehki vodi. Na tako obdelani tkanini smo nato z ekstrakcijo vzorcev poliestrne tkanine s petroletrom in z diklorometanom gravimetrično določili vsebnost oligomerov (metoda prirejena po DIN 54278-1).The fabric thus prepared was alkaline pretreated in a Mathis JFL laboratory dye at a bath ratio of 1:10. Soft water was used to prepare the pre-treatment bath. Pre-treatment in a bath with 1 g / l NaOH (pH 12) was carried out for 30 min. at 130 ° C. This was followed by washing the fabric three times in boiling soft water. The alkaline pretreated fabric was then stained at 135 ° C in a blind acid bath containing: 1 ml / l Eganal PS (Hoechst), 2 ml / l Lubit RL (Sybron / Tanatex) and CH 3 COOH 995 100% (JT Baker ) to pH 4.5-5 pH of the bath. The dyeing was performed according to the DyStar dyeing diagram recommended for Dianix AD dyeing. After dyeing, the fabric was washed four times in 40 ° C warm soft water. On the fabric so treated, the content of the oligomers was then gravimetrically determined by extraction of samples of polyester fabric with light petroleum and dichloromethane (method according to DIN 54278-1).
Dokazali smo, da smo s 30 minutno alkalno predobdelavo poliestrne tkanine pred kislim barvanjem pri 135° C znižali vsebnost oligomerov za 44% glede na tkanino barvano po kislem barvalnem postopku pri 135° C. Prisotnost oligomerov v ekstraktu smo potrdili z gelsko prepustnostno kromatografijo (GPC) in tetrahidrofuranom kot eluentom. S to metodo smo ugotovili, da je v vseh ekstraktih prisotnega največ cikličnega trimera, vendar se delež le tega spreminja glede na način obdelave. Pri alkalno preobdelani poliestrni tkanini je tudi delež cikličnega trimera v ekstraktu oligomerov za skoraj 7% nižji kot pri kislo barvani tkanini pri 135° C, kar priWe demonstrated that by 30 minutes alkaline pretreatment of polyester fabric before acidic staining at 135 ° C, the oligomers were reduced by 44% relative to the acid dyed fabric at 135 ° C. The presence of oligomers in the extract was confirmed by gel permeation chromatography (GPC) ) and tetrahydrofuran as eluent. With this method, we found that the most cyclic trimmer is present in all extracts, but the proportion of this varies depending on the treatment method. For alkaline-processed polyester fabrics, the proportion of the cyclic trimmer in the oligomer extract is also almost 7% lower than for the acid-dyed fabric at 135 ° C, which at
44 % nižji vsebnosti skupnih oligomerov predstavlja 51,79 % manj cikličnega trimera.The 44% lower total oligomer content represents 51.79% less cyclic trimmer.
Kot dokaz, da alkalna predobdelava pred kislim barvanjem ne vpliva na spremembo barvnega tona podajamo barvnometrične vrednosti izmerjene na vzorcu barvanem po kislem barvalnem postopku z 0,4% Dianix Rot AD - 2B in na vzorcu, ki je bil pred kislim barvanjem z 0,4% Dianix Rot AD - 2B predobdelan v kopeli 1 g/l NaOH 100% 30 min. pri 130° C. Vrednosti so podane v CIE L*a*b* barvnem sistemu :As evidence that alkaline pretreatment prior to acid dyeing does not affect the change in color tone, the colorimetric values measured on the acid dye sample with 0.4% Dianix Rot AD - 2B and on the sample prior to acid dye with 0.4 are given. % Dianix Rot AD - 2B pretreated bath 1 g / l NaOH 100% 30 min. at 130 ° C. The values are given in the CIE L * a * b * color system:

Barvnometrične vrednosti so srednja vrednost treh meritev na svetlordeče pobarvanih poliestrnih tkaninah. Rezultat DE* <1 pomeni, da naše oko spremembe v obarvanosti ne zazna. Vrednosti DE* 0,35 in DE*Color-metric values are the mean of three measurements on light-colored polyester fabrics. A score of DE * <1 means that our eye does not detect a change in color. DE * 0.35 and DE * values
0,38 sta zelo nizki, kar potrjuje enako obarvanost. Odstranjevanje oligomerov s to metodo ne vpliva na spremembo obarvljivosti in barvnega tona poliestrne tkanine pri kislem visokotemperaturnem barvanju.0.38 are very low, which confirms the same color. Removal of oligomers by this method does not affect the change in the color and color tone of the polyester fabric under acidic high-temperature dyeing.
S predobdelavo v alkalni kopeli znižamo izločanje oligomerov iz poliestra pri kislem barvanju pri 135° C za 44%.Tako znižanje zagotavlja nemoten barvalni proces poliestra v kislem mediju. Pri alkalnem barvanju se vsebnost oligomerov sicer zniža za 62%, vendar za njegovo izvedbo danes še ni na voljo dovolj v alkalnem stabilnih disperzijskih barvil. Z opisano predobdelavo in kasnejšim kislim barvanjem dobi poliester lep sijaj in svilen otip. Togost tako obdelanega poliestra se v primerjavi z običajno kislo barvanim poliestrom močno zniža, kar mu daje mehkejši otip.By pretreatment in an alkaline bath, the elimination of oligomers from polyester by acid dyeing at 135 ° C is reduced by 44%. While alkaline dyeing is reduced by 62%, the content of oligomers is still insufficient for its implementation in alkaline stable dispersion dyes. The described pretreatment and subsequent acid coloring give the polyester a nice sheen and silk feel. The rigidity of the polyester thus treated is greatly reduced compared to the usual acid dyed polyester, which gives it a softer feel.
Fizikalno mehanske lastnosti poliestrne tkanine se ne poslabšajo. 5 Metoda po izumu je posebno priporočljiva pri barvanju poliestrnih zaves v atlas in drugih vezavah, podlog za plašče in obleke, poliestrnih tkanin za oblačila in poliestrnih sukancev.The physical and mechanical properties of the polyester fabric do not deteriorate. 5 The method of the invention is particularly recommended for the dyeing of polyester curtains in atlases and other weaves, liners and dresses, polyester garment fabrics and polyester threads.
