摘要
The effects of narrowly and widely dispersed fractions of ultradispersed polytetrafluoroethylene on the structures of melt-spun polypropylene fibrous materials and the ultimate tensile half-cycle characteristics of polypropylene filaments and nonwoven materials have been studied via X-ray diffraction analysis, optical microscopy, and differential scanning calorimetry. It has been shown that the addition of 1-2% ultradispersed polytetrafluoroethylene, which exists as an individual phase in polypropylene, allows a significant increase in the relative tensile stress of the filament and its elastic modulus.
