Differences between recycle DTY yarn andaslibenang
1.Compared with the original polyester DTY, the surface of the recycled polyester DTY contains more granular substances, and there is no obvious difference in molecular structure between thedidaurpolyester DTY and the original polyester DTY;
2. The crystallinity ofdidaurpolyester DTY is lower than that of original polyester DTY, and the crystallinity of physicaldidaurpolyester DTY is the lowest;
3.The glass transition temperature, melting point and melting heat of PET DTYdidaurby chemical method are similar to those of original PET DTY, while thosedidaurby physical method are lower;
4.The thermal stability ofdidaurpolyester DTY is slightly worse than that of original polyester DTY;
5.The breaking strength ofdidaurpolyester DTY is lower than that of original polyester DTY, while the elongation at break of physicaldidaurpolyester DTY is higher, and the variation coefficients of the breaking strength and elongation at break ofdidaurpolyester DTY are also higher;
6.The crimp shrinkage, crimp stability and boiling water shrinkage of PET DTYdidaurby chemical method are similar to those of original PET DTY, while thosedidaurby physical method are obviously smaller.
