Description
Przy dzialaniu na welne zwiazkami chromu, zwlaszcza kwasem chromowym, staje sie ona, jak wiadomo, sztywna. Daje sie to odczuc bardzo dotkliwie przy farbo¬ waniu barwikami, które wymagaja trakto¬ wania kwasem chromowym lub innemi zwiazkami chromu, zwlaszcza kiedy dla pelnego utrwalenia barwika wymagany jest szczególnie wysoki dodatek chromianów lub kiedy, jak przy farbowaniu welny sztucznej, jest poddawany obróbce mate- rjal, który przedtem przeszedl proces chromowania.W mysl wynalazku mozna zapobiec przy farbowaniu welny, wywolanemu przez zwiazki chromu, pogorszeniu sie jej wla¬ snosci fizycznych, przez dodanie lugu blon¬ nika siarczynowego lub jego czesci sklado¬ wych jako to: soli kwasu lignino-sulfono- wego, smoly blonnikowej, cukrów, zwla¬ szcza pentoz i heksoz.Ton barwy i czystosc zabarwienia przez to nie zostaja zmienione, lecz przeciwnie welna zachowuje swa miekkosc i pelnosc i zdatnosc do tkania. Prócz tego pomie- niony lug blonnika siarczynowego dziala zarazem jako srodek zwilzajacy i ulatwia równomierne rozchodzenie sie barwika.Proponowano juz stosowanie odlugowin blonnika siarczynowego przy zaprawianiu welny. Ten poszczególny wypadek obej¬ muje równiez w sobie sposób niniejszy, który uwzglednia kapiele barwiace lub ka¬ piele wykonczajace.Przyklad L Do kapieli zawierajacej 3% barwika brunatnego chromowego 2 R 10% siarczanu — sodu <— kryst. 40% kwasu octowego 30%-ego 50% lugu blonnika siarczynowego 28° Be na wage towaru, wklada sie welne do. kapieli o 60° Ci doprowadza w ciagu pól godziny do gotowania i gotuje V2 godz.Dla wyczerpania kapieli dodaje sie 1V2% kwasu siarkowego i gotuje jeszcze % godz. Wtedy traktuje sie w podobnej kapieli 1,5% (na wage towaru) dwuchro¬ mianu potasu przez trzy kwadranse i wreszcie plócze.Przyklad IL Do kapieli zawierajacej 3% barwika brunatnego metachromu B 3% zaprawy metachromowej 2,5% lugu blonnika siarczynowego 28°Be na wage towaru, wklada sie welne przy 50° C, doprowadza powoli do gotowania i gotuje przez 2 godziny. Dla lepszego u- trwalenia barwika dodaje sie jeszcze 1% kwasu octowego 30%-ego i gotuje sie na¬ dal przez i/2 godz.Przyklad III. Dodaje sie do kapieli 2% blekitu antracenchromu XBf 10% dwuchromianu — potasu 30% siarczanu — magnezu 2% lugu blonnika siarczynowego 28° Be w stosunku do wagi towaru, wklada sie welne do kapieli 70° C, doprowadza w M godz do gotowania, gotuje przez 1 godz, dodaje powoli 1—2% kwasu octowego 30%-ego i gotuje dalej przez % godz. PLWool is treated with chromium compounds, in particular with chromic acid, and it is known to be stiff. This is felt very acutely when dyeing with dyes that require treatment with chromic acid or other chromium compounds, especially when a particularly high addition of chromates is required for the full fixation of the dye or when, as in the case of dyeing synthetic wool, it is subjected to a matte treatment. According to the invention, the deterioration of its physical properties, caused by chromium compounds, can be prevented during the dyeing of wool by adding sulphite fiber or its constituents as: sulfonic acid, fiber tar, sugars, especially pentose and hexose. The tone of the color and the purity of the color are thereby not changed, but on the contrary the wool retains its softness and fullness and suitability for weaving. In addition, the modified sulphite fiber lug acts as a wetting agent and facilitates the even spreading of the dye. It has already been proposed to use sulphite fiber deflection when dressing wool. This particular case also applies to the present method, which includes dyeing baths or finishing baths. Example L For a bath of 3% brown chromium dye 2 R 10% sodium sulfate-crystalline. 40% acetic acid 30% 50% sulphite fiber leach 28 ° Be by the weight of the goods, the wool is put into. 60 ° C bath, bring it to boil within half an hour and cook V2 hours. To exhaust the bath, add 1V2% sulfuric acid and cook another% hour. Then 1.5% (by the weight of the commodity) of potassium dichromate is treated in a similar bath for three quarters of an hour and finally a wash. Example IL For a bath containing 3% methachrome brown dye B 3% methachrome mortar 2.5% 28 ° sulfite fiber lug Regardless of the weight of the goods, the wool is put in at 50 ° C, slowly brought to cooking and simmered for 2 hours. For better dye fixation, a further 1% acetic acid 30% is added and the mixture is boiled for a further 1/2 hours. Example III. Add to the bath 2% anthracenchrome blue XBf 10% dichromate - potassium 30% sulphate - magnesium 2% sulphite fiber lug 28 ° Be in relation to the weight of the commodity, put the wool into the bath 70 ° C, bring it to cooking in M hours, cook for 1 hour, slowly add 1-2% acetic acid 30% strength and boil further for% hour.
