Özet: Twist is applied to the fibers to keep them together and to raise their strength. Twist per unit length changes the mechanical and performance properties of the yarn and the fabric structure. In this study, ring yarns were produced from polyester, viscose and polyester-viscose fibers in undyed and dyed forms and Ne 10, Ne 25 and Ne 40 counts and with 3, 3,5 and 4 twist coefficients. In the first part of the study, quality tests were performed on these yarns and the results were analyzed. Then, Ne 25 and Ne 40 yarns were transformed into single jersey fabric via a single bed SDL circular knitting machine. The fineness of the labaratory type knitting mill is not suitable for Ne 10 yarns therefore these yarns were not transformed into knitted samples. The obtained knitted fabrics were subjected to air permeability test in SDL Atlas air permeability tester. In the last part of the study, air permeability test was applied to the samples obtained from undyed yarns with Ne 25 from the produced fabrics at increasing pressure ranges. As a result of this study, the effect of twist coefficient on the air permeability of fabrics was tried to be determined. The results were analyzed through graphs and statistical programs.
