 Full text | Abstract: The present paper investigates the effects of knitted loop length on yarn fluctuation amplitude during feeding into a circular knitting machine. Variation of yarn tension causes a change in the loop length and yarn fluctuation amplitude. In order to study the behaviour of the yarn fluctuation amplitude during the feeding process, a new optical IR electronic monitoring system was designed and developed. Experiments were carried out on an industrial single jersey knitting machine with a plain knitted pattern and polyester 150 denier continuous filament yarn for three different knitted loop lengths. Evaluating the fluctuation amplitudes recorded by analysis of variance revealed that an increase in the loop length will cause a highly significant decrease in the yarn fluctuation amplitude. |
