Aniline Blue
To 100
pounds of fabric, dissolve 1 Ό pounds aniline blue in 3 quarts hot alcohol,
strain through a filter, and add it to a bath of 130 F.; also 10 pounds
Glaubers salts, and 5 pounds acetic acid. Immerse the goods and handle them
well for 20 minutes. Next heat slowly to 200° F.; then add 5 pounds
sulphuric acid diluted with water. Let the whole boil 20 minutes longer;
then rinse and dry. If the aniline be added in 2 or 3 proportions during the
process of coloring, it will facilitate the evenness of the color. |
