Abstract

When textile materials are treated with wet processes, attempts are usually made to detect organic and inorganic contaminant substances retained in the cloth either by allowing conductivity-measuring or other electrodes placed on the cloth to travel with it during transport, or by analyzing the fluid squeezed out of the cloth. The data obtained by these methods are extremely unreliable and subject to interfering factors. As a substantial improvement, it is proposed that the loading of the cloth with extraneous substances be measured in the interior of the cloth, between or at its surfaces. This can be achieved by applying and collecting solvent to extract samples of the extraneous substances from the cloth, section by section, and measuring the extraneous substances in the collected solvent quantitatively and/or qualitatively. Alternatively, the conductivity in the interior of the cloth, between its surfaces can be measured and used to determine the degree of contamination,
