Use of diluted viscose waste in the process of preparing complex yarn for aircraft fabrics

The possibility has been established of using dilute viscose wastes in the process of preparing a spinning solution for spinning complex viscose yarns which are used in the manufacture of aircraft fabrics.
Empirical equations have been obtained for calculating the change with time of ripeness indices and of free NaOH content of viscoses having an α-cellulose concentration of 5.0–8.4% by wt., plus calculated dependences which ensure determining the optimum ripeness index for spinning for viscoses which have been diluted in the range indicated.
It has been shown that, with decrease in α-cellulose and NaOH content of the spinning solution, the stiffness of complex viscose yarn is increased.
