I BENJAMIN FRANKLIN CRESSON of Philadelphia in the State of Pennsylvania
United States of America Manufacturer do hereby declare the nature of this
invention to be as follows:-
The fabric if to be printed will be treated with the solution the ingredients of
which are enumerated in schedule No. 2 given below and then treated with the
solution comprising the ingredients stated in schedule No. 1. If not to be printed
the fabric may be treated with only the solution of schedule No. 1 in the manner
described first below.
The pieces are twice padded through the solution of schedule No. 1 hereinafter
stated, in order that they may become thoroughly saturated, then dried by running
through the ageing machine at 140° F, then hung immediately; they must not be
allowed to lie, or they will heat.
Let them hang in the hanging room until they assume a dark green color which
usually requires 24 hours, during which time the temperature of the room must be
kept at about 85° F.
The pieces are then run through a cold solution of Bichromate of Potash at
6° Twaddell and are then well washed in cold water.
They are then to be dyed in Sumac using eighteen gallons at 2° Twaddell to
25 pieces, and then washed through clean water and finished.

The pieces are printed with the solution specified in schedule No. 2 and dried,
they are then padded on the Black machine with solution No. 1 going through the
nip and immediately upon the cans and just brought dry off the cans, care being
taken that they do not become too dry or they will become brown; they are
immediately hung and kept hanging just as in the process for the plain aniline
blacks hereinbefore described, likewise chromed and afterwards well washed in cold
water and then scoured in three soap baths to clear the whites; then mangled and
finished.
Having now particularly described and ascertained the nature of the said
Invention; and in what manner the same is to be performed I declare that what
I claim is ;
C
1. An aniline coloring solution containing the ingredients mentioned in Schedule
No. 1.
2. A resist acid for dyed aniline black containing the ingredients mentioned in
Schedule No. 2.
3. The method of dyeing aniline black which consists in padding the goods in a
coloring solution comprising the ingredients enumerated in Schedule No. 1, then
drying the goods, then hanging them in a hot room, then washing and finally
passing through a sumac-bath as set forth.
4. The method or process of printing and dyeing aniline black, which consists in
first treating with the solution of schedule No. 2, then with solution of schedule No. 1,
then chromed and washed, substantially as set forth.
