Conclusions
By x-ray analysis, we have confirmed the previously expressed hypothesis of a forced deformation of SÉVA on flow of an SÉVA—SPA mixture as a result of specific interaction of the components at the interface: the degree of orientation of the SÉVA macromolecules in the microfibres is higher than in a monofilament from the starting polymer.
It has been shown that ultrathin SÉVA fibres are characterized by a porosity, caused by micro- and macro-hollows, which causes a decrease in their strength as compared with the strength of ordinary SÉVA fibres.
