Abstract
A method of, and apparatus for, measuring the moisture content of flat textile structures, especially textile webs, wherein the test material is guided over at least one grounded ground-electrode and at least one further electrode is applied to the test material at the side opposite such ground-electrode. The surface of the further electrode is divided into positive, grounded and negative regions.

A method of measuring the moisture content of textile material, comprising the steps of guiding the textile material forming a test material over at least one grounded-ground electrode, applying at least one measuring electrode to the side of the test material opposite the ground electrode, dividing the surface of the measuring electrode into positive, grounded and negative regions, and measuring the conductivity of the textile material between the ground electrode and the measuring electrode.
An apparatus for measuring the moisture content of textile structures, comprising an electrode arrangement embodying at least one ground electrode at one side of the textile material defining the test material and at least one further electrode at the other side of the test material, said further electrode having a surface divided into zones of different potential, and amplifier means for measuring the current between said ground electrode and said further electrode.
