Abstract

The influence of drawing and molecular weight in a narrow range on the several structural‐mechanical properties of acrylic fibers have been investigated. Drawing of fibers (Ξ» = 3__x__–6,5__x__) leads to a considerable increase of tenacity. These data were explained with the orientation and perfection of structure. It was found that the molecular weight in closer range influences the density, perfection of structure, and the stability of fibers to repetitive deformation. The results show that the diversions of the average molecular weight, in the manufacture of commercial acrylic fibers, must be negligible.
