Investigation of Rheological, Thermal and Mechanical Properties of Recycled Poly (ethylene terephthalate)/Hyperbranched Polyester Blend Fibers

摘要：

　　To investigate the effect of hyperbranched polyester(HBPET) and concentration on the rheology, thermal and mechanical properties of recycled polyethylene terephthalate(RPET) fibers.Different amounts of hyperbranched polyesters (HBPET), 0.5 wt% and 1 wt% were added to the RPET.The influence of HBPET on the rheological, thermal and mechanical properties of produced fibers was investigated.Thermal stability and theological behavior of the pure recycled PET(RPET-0) and RPET-0.5 and RPET-1 blend prepared by melt compounding were tested by Thermogravimetric analysis(TGA), Differential Scanning Calorimetry (DSC) and parallel-plate rheometer.RPET-0.5 and RPET-1 blend were in a good agreement with improved rheological characteristics and led to significant enhancement in thermal stability.Decrease in the complex viscosity(η) of the blends was observed with increasing content of HBPET.On the other hand it was found that mechanical properties of the(RPET-0.5 and RPET-1) fibers were improved with respect to pure recycled PET(PET-0) fibers.Moreover the crystallinty of blended fibers was also increased with an increasing of HBPET content.
