Abstract
In this study, it is aimed to investigate the effects of filament yarn’s number of nips on bending rigidity of knitted fabric which is made of that yarn. For this purpose, polyester POY (Partially Oriented Yarn) filaments with 283 dtex linear density and 68 filaments in cross section were used as raw material. POY bobbins were intermingled at different speed and pressure levels thus yarns having five different numbers of nips were produced. Single jersey knitted fabrics were produced using these yarns on the circular knitting sample machine. According to ASTM circular bending test method, bending rigidity of knitted fabrics was determined by using the digital pneumatic stiffness tester. The effects of the change in the number of nips on the bending rigidity of knitted fabrics were examined and the test results were analyzed statistically.
