Description

Wykryto, ze barwniki, otrzymywane zapomoca sprzegania dwuazowanego kwasu 4-nitro-./-amino4)enzeno-2-sulfonowego z sulfokwasami 2-aminonaftalenu lub jego #-alkylo-pochodnemi, nadaja sie wysmie¬ nicie do drukowania welny zapomoca wy¬ trawiania. Odpornosc na dzialanie wody i swiatla efektów wytrawiania jest bardzo dobra.Przyklad. Barwnik kwas-4-nitro-7-a- mino-benzeno-2-sulfonowy-azb-kwas-2-me- tyloaniino-naftaleno-7-sulfonowy o steze¬ niu 2%, liczac na wage towaru, wybarwia sie w sposób zwykly na suknie welnianem z kapieli, zawierajacej sól glauberska, kwas octowy, i sukno to nastepnie drukuje pasta wytrawiajaca zlozona z 320 czesci wagowych formaldehydosulfoksylanu, 220 czesci wagowych tlenku cynkowego, 400 czesci wagowych zagestnika tragantowe- go — 65/1000, 60 czesci wagowych wody.Nastepnie suszy sie, paruje wilgotna para w ciagu 5 minut w aparacie Mather-Plaitfa, ¥2 godziny plócze na zimno, poczem su¬ szy. Otrzymane w ten sposób efekty wy¬ trawiania na zabarwieniu fioletowem o od¬ cieniu czerwonem sa odporne na dzialanie swiatla. Zabarwienia odznaczaja sie obok bardzo dobrej odpornosci na dzialanie swiatla i jednostajnosci nadspodzie¬ wanie dobra odpornoscia na dzialanie wody. PLDyes obtained by coupling diazotized 4-nitro / amino-4) benzene-2-sulfonic acid with 2-aminonaphthalene sulfoacids or its β-alkyl derivatives have been found to be exquisite for printing wool with etching. The water and light fastness of the etching effects is very good. Example. The dye-4-nitro-7-α-mino-benzene-2-sulfonic-azb-2-methylanino-naphthalene-7-sulfonic acid with a concentration of 2%, based on the weight of the goods, stains in the manner plain on a bath woolen cloth, containing Glauber's salt, acetic acid, and the cloth is then printed with an etching paste composed of 320 parts by weight of formaldehyde sulfoxylate, 220 parts by weight of zinc oxide, 400 parts by weight of traganthus - 65/1000, 60 parts by weight of water . Then it is dried, the moist steam evaporates for 5 minutes in the Mather-Plaitf apparatus, ¥ 2 hours it scours in the cold, then it dries. The red-tinted violet etching effects obtained in this way are resistant to the action of light. In addition to a very good light fastness and uniformity, the tints are distinguished by the fact that they have a good fastness to water. PL
