Abstract
Analysing the rate of dyeing curves of fibres spun with sulphuric acid or sulphuric acid-sodium sulphate baths by means of the method presented in Part I, some essential effects of spinning conditions on dyeing properties were discussed. And the following results were obtained.
In general, the dyeing ability of the fibre gose down and the surface color of dyed fibre becomes light and bright owing to its poor tendency to ring-dyeing by varying the spinning conditions as follows: (1) increasing the age of the viscose; (2) increasing the acid concentration; and (3) increasing the salt (sodium sulphate) concentration.
