Impact of yarn count, noil percentage and yarn tension on structure of jersey fabric

Klasičnim postupkom predenja na prstenastoj predilici ispredene su pređe iz egipatskog pamuka Giza 75 FG finoća 14,3, 16,7, 20,0 i 25,0 tex. Svaka od navedenih pređa ispredena je sa većim koeficijentom uvijanja i različitim postotkom isčeska 14, 16, 18 i 20 %. Na kružnopletaćem jednoigleničnom stroju malog promjera iz navedenih pređa izrađene su dvije grupe glatko kulirnih desno-lijevih pletiva s različitom napetosti pređe pri njenom ulasku u pletaći sistem. Prva je grupa uzoraka izrađena s uobičajenom napetosti pređe koja se koristi kod izrade ovakvih pletiva (0,15 cN/tex), dok je druga grupa uzoraka izrađena s većom napetosti (0,40 cN/tex). Dobivena mjerenja statistički su obrađena i testirana.Using the combed cotton spinning route, a number of yarns from Egyptian cotton Giza 75 FG with counts of 14.3, 16.7, 20.0 and 25.0 tex were spun. Each of the yarns were spun with a higher twist factor and different noil percentage of 14, 16, 18 and 20%. The yarns are being used to knit two groups of plain single jersey fabrics on a small diameter single bed circular knitting machine with two different yarn tensions at the knitting zone. The first group of samples was knitted with a usual yarn tension used in making knitted fabrics underwear (0.15 cN/tex), while the other group of sample was knitted with a higher tension (0.40 cN/tex). The measurements are statistically analyzed and tested
