Investigation of Open End Yarn Tension Using an Elastic Yarn-Guide [PDF]

open access: yesFibres and Textiles in Eastern Europe, 2021
This paper presents the results of Open End (OE) yarn tension investigation using a yarn-guide funnel with an elastic element. Obtained were the dependencies of tension change on such factors as body mass, elastic element rigidity, yarn coordinates on the funnel surface, and the speed of yarn moving.

Cross winding of yarn packages [PDF]

open access: yes, 2000
Random winding is widely used for the preparation of yarn packages used in a variety of textile processes. Ribboning caused by overwinding of yarn turns at certain places within the package is a basic problem encountered in this process. Standard random

Analysis of the Twisting Tension in the Direct-Twisting Machine and the Fitting Model Based on the Experimental Data

open access: yesApplied Sciences, 2022
The tension of the balloon yarn in the direct-twisting machine affects the yarn breakage and balloon shape, which in turn affects the energy consumption and yarn productivity of the direct-twisting machine.

Yarn Tension in Winding Mechanism.

open access: yesJournal of the Textile Machinery Society of Japan, 1966
Variations in stress in a yarn beam produced by the yarns wound on it were examined and recorded during winding. The yarns used were nylon filament and cotton yarn. The stress in the beam core in axial and circumferential directions was examined with wire strain-gauges attached inside the beam core.Data on the following subjects have been obtained from

Multiple response optimization of sizing machine settings and sized yarn tensile properties using advanced method of experimental design

open access: yesJournal of Engineered Fibers and Fabrics, 2023
On a loom, the warp yarns experience exceptionally high mechanical stresses and strains, as well as significant abrasion from friction. As a result, significant yarn breakages cause loom stoppages and, hence, production and quality interruptions.

Yarn tension model and vibration analysis during unwinding of carbon fiber bobbins

open access: yesJournal of Industrial Textiles, 2023
A low-quality unwinding process of the unwinding machine can lead to downtime of the knitting machine and loss of fabric quality. To address this issue, we studied the tension and vibration of carbon fiber yarns during unwinding.
