Yarn-Mass Measurement With 1-mm-Length Samples

J. G. Pinto、Vı́tor Carvalho、João Monteiro 等 5 位作者2007-04-01IEEE Transactions on Industrial Electronics

In textile production, measurement of yarn mass in the 1-mm range is of utmost importance to properly evaluate evenness, as several irregularities occur in 1–4-mm yarn length. Direct measurements in the 1-mm range are not available in commercial equipment. One of the most common, from Uster, is based on yarn samples o…
