THE LOCATION OF FIBERS IN YARN AND ITS EFFECT ON YARN HARDNESS

Abstract

In this article, changes in the initial moments of loading and unloading of yarn samples with the help of a newly created special strain gauge were studied.In the initial period of loading, the deformation of compact yarn is twice as slow as that of ordinary yarn (4 seconds), on the contrary, during unloading, ordinary yarn is slower (2 seconds), and compact yarn shrinks twice as fast (in 1 second) that in the experimental yarn the fibers are arranged more correctly. On the basis of Yu. N. Rabotnov's theory of creep, the change in the state of fibers in a thread during suspension of a load is theoretically determined and confirmed by the results of tensometric measurements.
