1. Instrument use
1. Place the yarn on the motor servo system, detect and calculate the network degree node by acupuncture method, test the number of nodes per meter of yarn, and the mechanical acupuncture system can also control the quality of the network degree, only reaching the operator setting The node of constant tension can be regarded as the effective network degree. The tension that can combine the monofilament is the key standard for the application of yarn in the textile. The quality of a bundle of filaments is determined by the nodes within a certain length, uniformity and strength. Decided.
2. Test by piercing the needle into the filament. This physical test method is based on the FZ∕T 5000 test standard, which can accurately measure the number of nodes.
2. Features of the instrument
1. The instrument has strong anti-interference line performance. It is not only designed for laboratories, but also can be placed on the side of the production line for timely testing. To ensure that the quality of the product is qualified, such as problems encountered in the production of filaments, they can be fed back in time.
2. This equipment uses a computer-controlled fully automatic servo system to automatically control pre-tension, stretching and sample removal. Greatly solve the interference problem. It can test filament yarns faster, more accurately and more effectively, saving labor and easy operation.
