【Abstract】 The main properties of colored PET drawn yarn of various specifications were determined. The effects of stretching ratio on mechanical properties and hot shrinkage of drawn yarn were studied. The results showed that the break tenacity was linear with stretching ratio, the elongation at break had a logarithmically hyperbolic function of stretching ratio, and the boiling water shrinkage was parabolic with stretching ratio.更多还原
