Development of Warp Yarn Tension During Shedding: A Theoretical Approach

Journal of The Institution of Engineers (India): Series E, 2014
Theoretical investigation on the process of development of warp yarn tension during weaving for tappet shedding is carried out, based on the dynamic nature of shed geometry. The path of warp yarn on a weaving machine is divided into four different zones. The tension developed in each zone is estimated for every minute rotation of the bottom shaft.

Statistical modeling of warp thread tension in automatic control of warping

Fibre Chemistry, 2008
Statistical modeling showed that there can be important scattering in the spectral characteristics of the tension compensators (TC) used as warp thread tension stabilizers in winding on the warp roller due to statistical scattering of the values of the parameters.

Warp Tension Control System Based on IMC

Applied Mechanics and Materials, 2014
To ensure stability of warp tension during weaving process, the paper presented a warp tension control system which uses two permanent magnet synchronous motor (PMSM) drive let-off and take-up mechanism respectively. Based on analyzing factors influencing warp tension, a warp tension mathematical model was established.

Auxetic behavior of warp knitted fabric under repeating tension

Textile Research Journal, 2021
In our previous study, a novel class of auxetic warp knitted fabrics were developed and their auxetic behaviors were studied under a single tensile test. However, during daily use, the fabrics are usually subjected to repeating tension rather than single tension. Therefore, the durability of the fabrics’ auxetic performance is of great importance.

The Research on Controlling Method of Loom Warp Tension

2009 Second International Symposium on Computational Intelligence and Design, 2009
In the textile industry, in order to better control loom warp tension and obtain better quality fabrics, it was very pivotal to choose a good control algorithm. This paper emphatically carried on the design and analysis on three control methods, they were PID algorithm, fuzzy PID algorithm and single neuron adaptive PID algorithm. This article took the

Reduction of Within-cycle Tension Variations in Warp-knitting

Journal of the Textile Institute, 1995
Tension variations within a knitting cycle of compound- and bearded-needle warp-knitting machines are shown to be large. A new tensioning system designed to reduce these tension variations is described. Results show that this tensioning system reduces the peak yarn tension to one-third of what it was with the conventional tensioning system.

Some of the Factors Influencing Yarn Tension in Warping

Textile Research Journal, 1952
The successful warping of coned yarn depends to a major degree on applying equal and con stant tension on each end of yarn so that smooth homogeneous beams are produced. This paper reports a study made to determine the factors which influence warping tensions.

Advances in yarn tension control for warp-knitting progress

Textile Research Journal
This study summarizes a three-dimensional logical framework of cause–detection–compensation for tension research by reviewing the issue of yarn tension fluctuation in warp knitting, which should help subsequent researchers to quickly grasp the development context of yarn tension research.
