dc.description.abstract | In Textile production, measurement of yarn mass in 1mm range is of utmost importance to evaluate evenness correctly, as several irregularities occur in 1mm to 4mm yarn length. Direct measurements in the 1mm range are not available in commercial equipments: yarn analysis is based on sample of 8mm. this paper presents a system which enables direct mass measurement in the 1mm range based on parallel capacitive sensors and signal processing techniques for detection of periodical errors. Results Point out that evaluation of yarn mass, with this approach, feasible in 1mm range, allowing on-line measurement (1mm yarn mass) in a spinning frame for real-time control. Spite low signal to noise ratio(SNR) it is possible to measure small variation of yarn mass (note that there is a typical capacity variation of 2,08E-17F for 57 tex - 0,057g/m of yarn). As a spin-off this project, a new low-coast job system was prepared for use in Knitting flat machines to control yarn break and Bobbin end. online quality classification is also feasible with the developed system | en |
