Investigating the effect of guide construction on yarn tension

open access: yesE3S Web of Conferences
This article examines the influence of the movement of yarn formed inside the spinning chamber along its surface, as well as the influence of friction of the yarn on the inner surface of the yarn outlet funnel on the tension of the yarn on the smooth ...

STUDY REGARDING YARN TENSION DURING KNITTING ON CIRCULAR MACHINE WITH SMALL DIAMETER [PDF]

open access: yesAnnals of the University of Oradea: Fascicle of Textiles, Leatherwork, 2015
If yarn tension is controlled properly during knitting, it gives an improved and uniform fabric appearance. The main objective of knitters is to feed yarn to the knitting point at a low and uniform tension.

Modelling yarn balloon motion in ring spinning

open access: yes, 2007
Air-drag on a ballooning yarn and balloon shape affect the yarn tension and ends-down (yarn breakage), which in turn affects energy consumption and yarn productivity in ring spinning.

The effect of yarn hairiness on air drag in ring spinning

open access: yes, 2006
Air drag on yarn and package surfaces affects yarn tension, which in turn affects energy consumption and ends-down in ring spinning. This study investigated the effects of yarn hairiness on air drag in ring spinning.

The bias-extension test for the analysis of in-plane shear properties of textile composite reinforcements and prepregs: a review [PDF]

open access: yes, 2016
The bias-extension test is a rather simple experiment aiming to determine in-plane shear properties of textile composite reinforcements. However the mechanics during the test involves fibrous material at large shear strains and large rotations of the ...
