=Dyeing of Plain Black.=--Diamine blacks find a very extensive
application for dyeing blacks on satin, either dyed direct in one bath,
or dyed, diazotised and developed.

Union black S and Oxydiamine black D are particularly suitable for
direct blacks, and are used either alone or in a combination with
Diamine jet black S S, which produces a better covering of the silk, or
with Oxydiamine black S O O O, which deepens the shade of the cotton.
According to the shade required Diamine fast yellow A and B, Diamine
green B or G, or Alkaline blue may be used for shading.

Dye for about one hour at about 175 deg. to 195 deg. F. in as concentrated a
bath as possible, with about 7 to 8 lb. dye per 100 lb. of satin, 8 to
16 oz. Glauber's salt and 5 to 8 oz. soap per 10 gallons dye liquor;
keep cool in the bath for some time and rinse.

The raising is either done in a tepid soap bath with the addition of
some new methylene blue, or in an acid bath to which Naphthol, blue
black, Acid green, etc., is added for shading the silk.

Direct dyed blacks are especially suitable for cheap goods (ribbons,
light linings, etc.), for which special fastness to water is not
required; also for tram and tussar silk plushes, which are afterwards
topped with logwood.

If greater fastness is required, and more especially if it is a case of
replacing aniline black, Diaminogene diazotised and developed is a good
dye-stuff. It is extensively used for dyeing umbrella cloths and
linings. Against aniline black it has the great advantage of not
