TY - JOUR T1 - THE EFFECTS OF VACUUM STEAMING PROCESS PARAMETERS ON TENACITY PROPERTIES OF COTTON AND VISCOSE YARNS AU - Şardağ, Sibel AU - Özdemir, Özcan AU - Kanık, Mehmet PY - 2011 DA - December Y2 - 2011 JF - Textile and Apparel PB - Ege University WT - DergiPark SN - 1300-3356 SP - 343 EP - 348 VL - 21 IS - 4 LA - en AB - In this study, the effects of vacuum steaming process parameters (temperature and duration) on tenacity properties of 100 % cotton and100 % viscose yarns were studied. For this purpose, the yarns with different twisting coefficients and numbers were twisted and exposed tovacuum steaming at different temperatures and for durations appropriate to their raw material properties. Tenacity properties of the yarnswere measured before and after vacuum steaming. The results obtained were assessed by means of SPSS statistical analysis program.Variation analysis and SNK test were carried out at 5% (0.05) level of significance. As a result of this study, it can be inferred that vacuumsteaming temperature has significant effect on tenacity properties of 100 % cotton and 100 % viscose yarns but vacuum steaming durationhas been found to be statistically insignificant on tenacity properties of cotton yarns, and viscose yarns.
