(57) By using printing pastes containing a high proportion, e.g. 8 to 15% by weight, of
a humectant such as urea or glycerol, fabric printing processes may be developed which
can be used both on fabric webs and on garments or garment panels with equal ease.
Following the application of the printing paste, and before it has materially dried
out, the fabric is confined between a pair of impermeable layers and heated to greater
than 100°C.
The process is particularly advantageously applied to discharge printing in connection
with which it is possible to use discharge printing techniques without the necessity
for subsequent washing out and with the production of a visible discharge print immediately
after the heat treatment step just noted.
