For their excellent physical and chemical properties, PTFE hollow fiber membranes can be used in harsh environment of water treatment.
Factors as the ratio of extrusion, the temperature of extrusion, the speed of extrusion and the parameters of the die affect the performance of the fibers. [1-4] The die with a certain taper of 40 ° ~ 60 °, the taper die and the extrusion of the pressing, due to the shear force formed by the taper, is compacted between the PTFE particles and form a fibrillated, as shown in Figure 1(a), but this option does not destroy the spherical structure, so that the fibers have sufficient strength to be stretched.
Factors affecting the stretching effects include the stretching temperature, stretching speed, and stretching ratio.
Sintering temperature, sintering time and cooling mode affect the structure of the porous and the crystallinity of PTFE.
After sintering, we remove the membrane in air for cooling or slowly cooling in the machine. 2.2 Performance testing Measured the mechanical properties at the universal mechanical experimental machine, set the machine at a pitch of 100mm, a tensile speed of 50mm/min, the test results directly obtain the breaking strength, elongation at break and other parameters.

Merklein research group systematically investigated the thermal mechanical property of the hot stamping steel [1], and some process problems [2].
Therefore, at this stage, affected by these two factors, the die strain increased rapidly.
Combined effects of these two factors, the strain show a slowly down trend with time.
This estimate ignored the mold surface work hardening and other factors which are all the positive impact of die life.
