An Evaluation of Fiber Parallelization and Drafting Tenacity of Cotton Sliver

Abstract

The effects of fiber parallelization and drafting tenacity were investigated on several cottons. The average drafting tenacity was directly related to the total amount of hooks present before drafting. When one cotton was processed through eight drawings, the total amount of hooks and drafting tenacity after each process were logarithmically related to the number of processes, with a decrease in slope occurring for each property after the fourth drawing process. When the majority hooks trailed at first and second drawing, fiber parallelization increased over the conventional drafting direction. Post- combing drawing does not reduce the amount of hooks significantly. A linear relation ship exists between hooks in roving and hooks in the sliver fed to the roving frame.
