Abstract

Abstract In this work, the method, in principle of the box complex algorithm was adopted to obtain stress-induced crystallization coefficient C and the strain-optical coefficientA op with the value of 295 and 1.5×10−9, respectively, and some parametersA 1=0.27,A 2=5.06,a=3.5,b=1.8 relative to the elongational viscosity of poly(trimethylene terephthalate)(PTT) fiber. The vitrification distance as a function of the take-up velocity and mass throughput was also gotten. The effects of spinning conditions on filament temperature, velocity gradient, spinning tension, birefringence and crystallinity, and effect of viscoelasticity on take-up velocity had been discussed.
