Abstract : This study was carried out in order to predict the knitted fabric irregularity based on yarn irregularity. Using the
Uster statistics of yarn mass irregularity, the knitted fabric specifications were determined. In order to build up a
theoretical model, the sine function of the Non-linear regression function was applied for 14Ne polyester/viscose
(65/35) yarn using the Orign program. The sine function was chosen because it shows the best fitting results
compared with the different functions. The result obtained from the proposed model shows a high correlation and
good significant. Furthermore, the results obtaining using the Non-linear regression equations shows optimal
correlation with experimental results for yarn used in this study.
