WDPET is a kind of polyester chip for sea-island spinning,which is further modified on the basis of COPET. In addition to retaining the advantages of COPET's excellent spinnability, low thermal degradation, and clear cross-section, It also get the characteristics of higher spinning speed and faster fiber opening by adjusting the proportions of components and conditions of polymer chain formation.

Main quality index:
Quality index of WDPET
Note:
1.The M1 in the table is the median value of intrinsic viscosity.in general M1=0.61 or it should be determined by both buyer and seller.
2.M2 in the table is the median value of color b, special requirement M2=2 or it should be determined by both buyer and seller.
[Test method:]
All the above medxes are tested colording to GB/T14190-93, and the solvent used in the intrinsic viscosity test is phenol tetrachloroethane:(1:1), the melting point is tested with microscope method, and the color with Hunter tricolor method.
