Abstract: The loop length which is decided during the knitting process and the yarn tension developed inside the knitting zone are the two crucial output variables of the loop forming system and hence used to validate the proposed model of 1x1 rib loop formation on a dial and cylinder machine. For the purpose, 66 fabric samples have been produced with known input variables. The loop length of the dry-relaxed fabrics has been measured in first 50 samples and the cam force during knitting has been measured in last 16 samples. These measured values have been compared with the predicted values of the model generated, employing the same input variables. Barring a few cases, there is a reasonable agreement between measured and predicted values. The causes of disagreement are also traced wherever possible. The actual amount of overestimation/underestimation of the model is also calculated. The model, in general, slightly underestimates the loop length. The peak cam force also tends to be underestimated at CKP2 and overestimated at CKP.
