Abstract

According to the invention, in order to obtain viscose rayon directly dyed in two colours simultaneously, a second line for spinning is introduced to the existing one, as the first (38.1) and the second (38.2) pipe collectors, parts of these spinning lines, filled up with differently dyed viscose solution, supply respectively dosing pumps (22.1 and 22.2) at the first and second working positions of the spinning machine, which are powered by one and the same electromotor and work synchronously. The cellulose solution filled up in the added second pipe collector (38.2) is coloured in mass by the additionally mounted and operating independently second individual dyeing installation (10-1), so that differently dyed viscose fibers are being spun at the neighbour working positions. Then the spun at these neighbour working positions single-colour dyed rayon fibers are brought together, according to the innovative spinning design of the invention and are gathered in a common centrifuge to obtain a viscose rayon cake, directly and simultaneously dyed in two contrasting or gradating colours or colour mixtures.
