【Abstract】 In this article, the fusibility, mechanical and dynamic mechanical propertiesof the far infrared polypropylene (PP)fibre material are analysed. The results show thatthe powder in the far infrared PP fibre has great influence on the fibre properties. Theshearing stress and apparent viscosity of the melting material are higher than PP. Thefar infrared PP fibre has good draw properties. The breaking strength and modulus increased with the increasing of draw times and the elongation at break reduced.更多还原
