Influence of PET Aggregate Structure on Physical Properties of Polyester Fully Drawn Yarn
①The greater the degree of molecular orientation of PET, the greater the breaking strength of the fiber, and the smaller the elongation at break; ②the greater the crystallinity of the PET molecule, the stronger the rigidity of the fiber, the greater the breaking strength, and the smaller the elongation at break; ③ Polyester fully drawn yarn The main determinant of the boiling water shrinkage rate is the orientation and de-orientation of the PET polymer chain; ④ The crystalline structure of the PET molecule is the key to determining the dyeing performance of FDY; Guaranteed rate and dyeing performance.
