PROCESS OF TREATING ANIMAL FIBERS.
N Drawing. Application filed December 6, 1927, Serial No. 238,224, and in Germany June 16, 1926.
This invention relates to a process of treating animal fibers in an acid bath with a sulphonated derivative of naphthylamines of the general formula wherein Y means H or univalent substituents such as OH, NH or halogen and wherein R and R mean H, alkyl, aryl or substituted aryl residues and w stands for a whole number not greater than 2, these naphthylamine derivatives containing at least one ,SO H
group, and then treating the fibers with a formula NHQNHz, O 311 10 parts of crystallized sodiumsulphate and 5 parts of acetic acid. The temperature is raised to boiling, 3 parts of sulphuric acid are added and the whole is boiled for 1 hour. After the goods have been washed they are handled for abouthalf an hour in an boiling bath of-3 parts of potassium bichromate and 3 parts of sulphuric acid in 4000 parts of water, whereby a black having a full bloom is produced on the fiber;
@NEONQ, HOaS is used.
Example 2.100 parts of wool are entered at ordinary temperatureinto a bath consisting of 4000 parts of water, 6 parts of 1.4-di-(6- In similar manner a black dyeing is obsulpho-Q-naphthylam'in) -benzene of the for mula 10 parts of crystallized sodium sulphate and 5 parts of. sulphuric acid. The temperature is raised to theboiling, boiling continued for one hour, 3 parts of potassium bichromate added and boiling continued for a further half hour; the goods are then washed and dried, there is thus obtained afast deep black.
E wample 3.100' parts of wool are entered into a bath consisting of-6 parts of the sodium salt -of 4-a-naphthylamino-4-aminodiphe- HOaS 'nylamine-2-sulphonicacid of the formula 10 parts of crystallized sodium sulphate and 15 parts of acetic acid in 4000 parts of water. The bath is maintained boiling for an hour, where upon the wool iswashed and handled for about half an hour in a boiling hot bath of 3 parts of potassium bichromate and 3 parts of sulphuric acid in 4000 parts of water,
whereby a fast black is produced.
The like result is obtained when 4-,8-naphthylamino 4 aminodipheuylamine 2 sulphonic acid of the formula is used.
E wample 4.100 parts of wool are treatedas above described in a bath consisting of 6 parts of the sodium salt of 4-B-naphthylamino-4'-oxydiphenylamine-Q-sulphonic acid of the formula v v @NHQNH-O-OH,
10 parts of crystallized sodium sulphate, 10 parts of sulphuric acid and 4000 parts of water. The washed wool is then subsequentin a bath consisting of 6 parts of the sodium 1y treated as described in Example 3. There salt of 1.4-di (4-,8-naphthylamino-Q-sulphois produced a fast full black.
- I Example 5.100 parts of wool are handled phenylamino) -benzene of the formula @buP-ONHfONEkQ- m;
10parts of crystallized sodium sulphate, 4
I parts of sulphuricacid and 4000 parts of water for 1 hour while the. bath is boiling hot; the treatment is then continued in the same bath for half an hour after addition of 3 parts of potassium bichromate. There is produced a fast black dye.
A like result is obtained when the correspolnding a-naphthyl derivative of the formu a Y is used.
Example 6.100 parts of wool are boiled for one hour in a bath consisting of 6 parts of H|O NH H 7 311 10 parts of crystallized sodium sulphate, 4
parts of sulphuric acid and 4000 parts of water; after washing the goods they are further threated in a boiling bath of 3 parts of duced a full blue black.
potassium bichromate and 3 parts of sul phuric acid in 4000 parts'of water for half an hour. There is produced a deep black.
Example 7.-100 parts of wool are handled for 1 hour at the boiling point in a bath consisting of 3 parts of 2.6'-di(4-amino-2-sulphophenylamin'o) -naphthalene of the formula NHAC +NH2 Elm-GEN sour 10 parts of crystallized sodium sulphate, 4 parts of sulphuric acid and 4000 parts of water and then for a further'half an hour in thesame bath after addition of 15 parts of potassium bichromate. There is produced a dark green dyeing. v
E xample 8-100 parts'of weighted silk are handled in a bath of 16 parts of 4 aminosulphophenyl-2-naphthylamine (see Example '1) 15 parts of acetic acid, 10 parts of crystallized sodium sulphate and 1000 parts of water which is kept boiling hot {the goods are then washed and after-chromed.
