Effect of Heat Treatment on Morphology and Tensile Properties of one-step Process BSY
This paper study the morphology structure and tensile properties of bi-shrinkage yarns (BSY), which is preorientted yarn (POY)/fully drawn yarn (FDY) composite yarn produced by one-step spinning processing. The lengthways morphology of BSY before and after boiling water treatment are analyzed by optical microscope. The results show that highshrinkage yarn POY construct the skeleton of BSY, and low-shrinkage FDY form filament loops on the surface of BSY. Tensile curves of BSY have two peaks, which means that the two components do not break at the same time, FDY were broken first, and then POY were broken. BSY breaking process are different before and after treated in boiling water. The breaking tenacity of BSY is mainly decided by FDY, and the initial modulus of BSY is mainly decided by POY.
