| Abstract: | The effects of different amount of chemical degradation agent on melt index, melt point and rheological property of far\|infrared PP blends were investigated. Meanwhile, the crystallinity and orientation of fine far infrared PP fiber in high speed spinning process were also observed. The results showed that by adding 3% chemical degradation agent, the rheological property of far infrared PP blends was improved and the spinning temperature was decreased, causing the spinnability greatly improved, thus they fitted high speed spinning. Furthermore, the supermolecular structure of the resulted fine far infrared PP\|POY fiber was favorable to the afterprocess. |
