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.

Underwater warp tension meter [PDF]

open access: yes, 1970
A self-contained electronic solid-state instrument capable of measuring the tension between the different parts of a trawl net in operation, has been designed and developed for the measurement in the range 0 to 300 kg with an accuracy of ± 2 kg. The instrument is useful for measuring the resistance to motion of various accessories of a trawl net.

Investigation of bending and drape properties of woven fabrics and the effects of fabric constructional parameters and warp tension on these properties

open access: yesTextile Reseach Journal, 2012
In this research, bending and drape properties of woven fabrics and the effect of weft density, weft yarn count and warp tension on these properties were investigated. Higher values were found for bending rigidities of the fabrics woven with thicker weft

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

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.

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.
