| Abstract: | Poly(butylene terephthalate)(PBT) and poly(ethylene terephthalate)(PET) were blended in certain proportions to spin large diameter monofilaments.The effect of the blending ratio and post-drawing technology on the compatibility and tensile strength of the blending monofilaments were studied by mechanical properties testing,scanning electron microscopy and thermal property analysis.Results showed that the knot strength was raised by blending of PET-PBT.The liquid cooling temperature,the stretching ratio and t... |
| Keywords: | monofilament blend structure mechanical property |
