In this study, %100 combed ring, compact, open end rotor and vortex (MVS) yarns with different yarn counts, which were used from the same raw material blend were produced and wound to same package density according to the principle of loose winding and the physical properties of the yarns were tested. The bobbins were dyed with reactive dye for different three dyebath concentration in the universal package dyeing machine and were dried with a high frequency drier. Single jersey knitted fabrics was produced using same machine parameters on the sample circular knitting machine and bending resistances were measured by the digital pneumatic stiffness tester. The test results were analyzed by using statistical methods. In the results of analysis of variance, spinning system and yarn number were found as significant at significance level (Sig. p<0.01) on the bending resistance values.
