The online yarn testing system measures the electrical resistivity [Ohm.m] or sheet resistance [Ohm/sq]. Defects such as filament breakages, twist, splice, fuzz, fold, entanglement can be detected via threshold monitoring. The system is particularly designed for online control of high-value conductive fibers with a data rate allowing users to monitor at production speeds of up to 10 m/s. The textile industry typically employs a stack of 10-200 sensors to monitor the entire fabric. The sensors operate independently and feed data directly to a PLC for immediate process control. The standard sensor applications for carbon fiber processing are monitoring of carbonization; outbound carbon fiber bobbin control; quality control of TowPreg and tape slitting; online process control of fiber spreading; tape laying and filament winding e.g. for high-pressure gas tanks. A further application is the measurement of the resistivity of conductive coatings such as copper or nanowires (CNT or AgNW) for the smart textile industry, again without contact to the material. In addition, the sensors can be used for quality monitoring of high resistive metal filaments which are used for EMI shielding. The SURAGUS testing solution supports the improvement of product quality by direct process control, the increase of material yield, and by conducting incoming and outgoing goods inspection.
