Flex fatigue of PET/PEN fibers
Original language description
PEN fibers are well known for their high performance properties, resistance and good tensile properties. Their potential markets are packaging, films and fibers. Especially for tire yarns the response to cyclic dynamical deformation is interesting. Blends of PET and PEN have been attracting increasing interest because they combine the superior properties of PEN with the economy of PET. Mixture of these polyesters form due to transesterification during melts processing random copolymers. The glass transition temperature of PET/PEN increases linearly with volume fraction of PEN. It is therefore possible to control properties connected with Tg by including of PEN to PET. The addition of PEN improves gas barrier properties as well. The main aim of this contribution is measurement and characterization of flex fatigue behavior of PET/PEN fibers. These characteristics are obtained at constant pre-straining. The analysis is based on distribution of flex fatigue life (in cycles). The explorator
