   4. Man färbt gleiche Teile Baumwolle und Wolle mit 1% des Azofarbstoffes   4-Amino'l-oxy-     benzol-2-carbonsäure # 1-Aminonaphthalin sauer # 2-Amino-8-oxy-napthalin-6-sulfonsäure   unter Zusatz von 30% kristallisiertem Natriumsulfat, 0-5% Natriumcarbonat kalziniert und 2% eines   wasserlöslichen Harnstoff-FormaIdehyd-Vorkondensationsproduktes.   Die zum Verkochen neigende Färbung zeigt nach einstündigem Kochen den normalen Farbton.

   3. Cheeses made from 70 parts by weight of wool and 30 parts by weight of visose synthetic staple fibers are dyed with 2% of dye no. 540 of the dye tables of Schutz, 7th edition, and 5% methylurea obtained by reacting methylamine sulfate and potassium cyanate
 EMI2.2
 



   4. Equal parts of cotton and wool are dyed with 1% of the azo dye 4-amino'l-oxybenzene-2-carboxylic acid # 1-aminonaphthalene acidic # 2-amino-8-oxy-napthalene-6-sulfonic acid with the addition of 30% % crystallized sodium sulfate, 0-5% calcined sodium carbonate and 2% of a water-soluble urea-formaldehyde precondensation product. The color, which tends to overcook, shows the normal color after boiling for one hour.
