Yarn sensors - Fil Control

During the yarn processing, the sensor purpose is to immediately and automatically detect the breakage or stoppage of one or more yarns. The sensor will give the operator on duty an alarm with a visible LED flashing signal. It will simultaneously send out an electrical signal to the yarn cutter to cut off the broken yarn and grip the cut end, or send a digital signal to the PLC.

Braiding a New Approach of Making Sensor Yarn for Textile ...

· Owing to the principle of wound monitoring, the sensor yarn is made by the combination of an electro-conductive component (Electrode) and a yarn from biocompatible fibre (Isolator) which can change its electrical properties due to environmental conditions, for example- swelling. Practically it can be constructed by Braiding, Twisting and Friction spinning machine. According to recent design approach and theoretical point of view, sensor yarn …

Sensor Yarn - an overview | ScienceDirect Topics

In a conventional system of a multiaxial warp knitting machine, the sensor yarns can be introduced over the entire working width of the machine by laying weft yarns only in 90° ± 45° angular positions and warp yarns in 0° direction using static yarn guides. This limits the realization of the aimed sensor design for the SHM of the turbine blade to a great extent. This space-saving sensor design can be …
