Özet
Polypropylene (PP) is a versatile and widely used polyolefin polymer with outstanding propertiessuch as low density, easy processability, lower cost, low melting point, etc. Properties of the polymer, fibercross-section and process parameters have an important influence on the filament yarn properties. In this study,PP filament yarns as C-shaped and round cross-sectional shapes were produced with five different drawingratios by using CF and BCF yarn types. We focused on changes of yarn test results (linear density, tenacitybreakingelongation, shrinkage in boiling water and the amount of spin finish lubricants) with the effect ofdrawing ratios, cross-sectional shapes and yarn types (CF and BCF). The findings from this study make severalcontributions to the current literature. We found that drawing ratios, cross-sectional shape and yarn types areeffective on the testing results separately. Furthermore, these differences are statistically significant when theireffects are taken together.
