    摘要： Cellulose derivative spinning solutions are provided, having an improved flow rate at comparable cellulose derivative content and pressure drop across the spinning nozzle, or a higher cellulose derivative content at comparable flow rate, comprising a cellulose derivative in solution in a solvent therefor, and a polyethylene glycol soluble in the solution and having an average molecular weight within the range from about 1.1 to about 4.5 million, in an amount to improve flow rate or increase cellulose derivative content; as well as a process for spinning such solutions through a spinning nozzle at improved flow rate or increased cellulose derivative content.
