This paper discusses the influencing factors on the pressure of flyer presser and on the relationship between the presser pressure and the roving tension by means of analysing and measuring the presser pressure during winding on the flyer frame.

On the roving tension to the roving quality influence,this article introduced the influence roving tension factor and the stable roving tension measure,thus enable the roving quality to obtain certain guarantee and the enhancement.

Analyses of Dryer Yarn Tension of Three New Type Sizing Machines;

The Research of Ring Spinning Theory Based on Balloon Shape and Yarn Tension;

Various measurements of yarn tension in textile process have been discussed.

Introduction is done to the PXI bus based test system of weft tension of air-jet looms and test of some air-jet looms regarding the specification finds the advantages of the system in quick response,easy programming,reliable,strong anti-interruption,precision test and universal in application in contrast to the conventional one.

It points out that rationally setting weft-related process parameters, reducing weft tension and taking strict control over the quality of filling yarn are effective measures for r.

A VIbased novel method for testing weaving looms' weft tension is given in the paper.
