Abstract


The textile industry, particularly in theweaving areas, needs sensors to monitor for faults and to aid the automation ofwarp yarn repair. As MEMS (Micro Electro Mechanical Systems) technologyadvances, sensors and actuators get smaller. MEMS sensors are very powerful andare highly accurate. These sensors are inexpensive and are readily available.Currently, in the textile machinery, drop wires are used to monitor the tensionof the warp yarns in the weaving process. These drop wires are abrasive to thewarp yarns and can lead to more warp yarn breaks. Therefore, it would bebeneficial to develop a system that does not contact the warp yarn in any way,such that extra warp yarns are not broken because of the sensor. This researchhas led to the development of a sensor system that has no contact with the warpyarn. The main purpose was to show proof of concept for applying a MEMS sensorto the textile machinery, specifically the Jacquard Loom, in order to develop asensor system having no contact with the warp yarns. A MEMS Accelerometer,available from Analog Devices, was used to monitor the motion of the heddle,whose acceleration properties change based on the presence of the warp yarn.Matlab was used to interpret the data and analyze for broken warp yarns (usingrecorded data) based on the change in acceleration. Once a warp yarn isdetermined to have been broken, Matlab would notify the user.
