Abstract
The responses of tension in a running yarn given stepwise friction at two points and drafted stepwise at two other points in the winding system have been studied with the following results:
Assuming the yarn to be perfectly elastic, the tension is readily calculable and agrees well with experimental results on nylon and cotton yarn. To make a more exact estimate, the effects of tension “Career” and creep of the yarn must be taken into consideration. “Career” means the amount of tension a sample received being used in our experiments.
