A new approach of prediction of yarn diameter

Abstract

In the present study, an attempt has been made to obtain the relationships for prediction of yarn diameter from different fibers and spinning technologies. The Peirce formula is found to give high deviation from the observed values of yarn diameter because it does not take the effect of twist, type of fibre and spinning technology into consideration. A new empirical model has been proposed that takes into account the parameters affecting the yarn diameter to a great extent, namely yarn twist, spinning technology and type of fibre in calculating the yarn diameter. The spinning technology, type of fibre and the proportion of fibre in the yarn have significant effect on yarn diameter. The proposed model is able to predict the yarn diameter more accurately.
