Description

Zauwazono, ze wogóle zdolnosc wchla¬ niania wlókien zwierzecych w obecnosci kwasów znakomicie wzrasta za dodatkiem aromatycznych kwasów sulfonowych.W przemysle welnianym wymaga sie w charakterze reguly, aby farbowany towar ladowano do wanny farbierskiej w stanie wilgotnym, gdyz towar suchy osiada w wannie kwasnej zbyt wolno, co wywoluje niejednostajne jego barwienie. Zauwazono, ze dodatek sulfokwasów aromatycznych do wanny farbierskiej kwasnej sprawia tak szybkie wilgotnienie towaru, iz uprzednie zwilzanie jego staje sie zbytecznem. Mozna równiez towar zweglony ladowac do wan¬ ny bez plókania lub zobojetniania, nie o- bawiajac sie otrzymania, nawet w wypad¬ ku farb czulych, zabarwienia niejednostaj¬ nego. Szczególnie szybko zwilza sie za do¬ datkiem sulfokwasów aromatycznych do wanny kwasnej towar zweglony.Wystarcza tu drobna domieszka kwasów aromatycz¬ nych do wanny farbierskiej.Stwierdzono ponadto równiez, ze przy domieszce podczas zweglania pewnych srodków zwilzajacych, a zwlaszcza sulfo¬ kwasów aromatycznych, np. kwasów sulfo¬ nowych naftalinu, albo naftalinu uwodorod- nionego do wanny kwasnej mozna stezenie jej obnizyc do polowy stezenia zwyklego, osiagajac pomimo to calkowite zniszczenie zanieczyszczen roslinnych welny. Dodateksrodka zwilzajacego db wanny kwasnej nie zmienia wlasciwego procesu zweglania.Nizszy stopien stezenia wanny kwasnej nie- tylko, ze wplywa mniej szkodliwie na wla¬ snosci welny (obróbka welny w wannie kwasnej stosunkowo mocnej o przecietnie 4° Be uszkadza jak to wykazaly badania nowsze, wlókno welny w stopniki pokaz¬ nym), lecz obniza jeszcze niebezpieczen¬ stwo powstawania tak zwanych plam zwe¬ glenia, pojawiajacych sie, jak wiadomo, na welnie barwionej sztukami, wskutek tego, ze wyjete z kapieli zweglajacej biale sztuki towaru, pozostajac-w stanie zakwaszonym, czesciowo wysychaja pod wplywem wlo- skowatosci. Pod wplywem wloskowatosci powstaje wówczas nagromadzenie kwasów i dalsze rezerwowanie welny. Przy dalszem farbowaniu podobnych sztuk welna w tych miejscach staje sie jasniejsza, barwi towar nie jednolicie i czyni go brakownym. Sztuki tkaniny o podobnych plamach zweglenia mozna zbywac jedynie po przefarbowaniu ich na czarno, W charakterze srodka zwil¬ zajacego nadaje sie bardzo dobrze np. ben- zylonaftaleno-zywico-sulfonian sodu. Moze byc korzystnem zastosowanie kwasów sul¬ fonowych w postaci soli.Plókanie welny garbarskiej, zawieraja¬ cej wskutek lugowania wiek wapnia, spra¬ wia trudnosci, albowiem warstewka tlusta, otaczajaca wlosie welny, przeciwstawia sie energicznie obróbce kwasem solnym celem usuniecia wapna. Dzieki natomiast dodatko¬ wi aromatycznego sulfokwasu kwas solny poczyna szybko i energicznie dzialac i za¬ pewnia tak dokladne usuniecie wapna, ze mycie welny mozna uskutecznic bez jakich¬ kolwiek trudnosci zwyklym sposobem lu¬ gami i mydlem.Przyklad, Do 1000 litrów zimnej wan¬ ny z kwasu siarkowego 2° Be dodaje sie 21/2 kg benzylonaftolen^-zywico-sulfonianu so¬ du, w plynie tym obrabia sie przeznaczona do zweglenia welne lub tkanine welniana w ciagu y% godziny i prowadii sie dalszy proces zweglania sposobem powszechnie znanym. Otrzymuje sie w ten sposób po¬ dobniez skuteczny rozklad zanieczyszczali roslinnych welny, jak w wypadku wanny z kwasu siarkowego o 4° Be. PLIt has been noticed that the absorption capacity of animal fibers in the presence of acids increases greatly with the addition of aromatic sulfonic acids. In the wool industry, it is required as a rule that the dyed goods should be loaded into the dyeing bath in a wet state, because dry goods settle in the acid bath too slowly which causes its uneven staining. It has been noticed that the addition of aromatic sulfo acids to an acid dyeing bath causes the product to become wet so quickly that its prior wetting becomes redundant. It is also possible to load charcoal goods into the bathtub without creaking or neutralizing it, without fear of obtaining, even in the case of sensitive paints, a non-uniform color. The charcoal goods are wetted particularly quickly with the addition of aromatic sulfo acids to the acid bath. A fine admixture of aromatic acids to the dyeing bath is sufficient here. It has also been found that during carbonization, certain wetting agents, especially aromatic sulfo acids, e.g. The concentration of naphthalene sulphonic acids or naphthalene hydrated into the acid bath can be lowered to half of the usual concentration, nevertheless achieving complete destruction of vegetable impurities in wool. The addition of an acid bath moisturizer does not change the proper carbonization process. The lower concentration of the acid bath not only has a less harmful effect on the properties of the wool (the treatment of wool in a relatively strong acid bath, with an average of 4 °), does not damage the fiber, as shown by newer studies, wool in the footers shown), but it reduces the risk of the so-called charring stains appearing, as is known, on piece-dyed wool, due to the fact that the white pieces of goods removed from the charcoal bath remain acidified. , they partially dry under the influence of hairiness. Under the influence of hairiness, an accumulation of acids develops and further reserve of wool. With the further dyeing of similar pieces of wool in these places, it becomes lighter, it colors the goods not uniformly and makes them scrap. Pieces of fabric with similar charring stains can only be disposed of by dyeing them black. For example, sodium benzyl naphthalene resin sulfonate is very well suited as a wetting agent. It may be advantageous to use sulfonic acids in the form of a salt. The flaking of tanning wool, which has a calcified age as a result of leaching, is difficult because the greasy film surrounding the wool hair is vigorously opposed to the treatment with hydrochloric acid to remove the lime. However, thanks to the addition of an aromatic sulfo acid, hydrochloric acid works quickly and vigorously and ensures that the lime is removed so thoroughly that washing the wool can be done without any hardship using the usual method of using soap and soap. Example: Up to 1000 liters of cold bath tub. from 2 ° Be sulfuric acid, 21/2 kg of sodium benzylnaphtholene-resin-sulphonate are added, in this liquid, the charcoal or woolen fabric is processed for y% of an hour and the further charring process is carried out in a manner known per se. An effective decomposition of vegetable soiling on wool is thus obtained, as in the case of a tub of sulfuric acid with 4 ° Be. PL
