Abstract
AbstractThe peculiarities of the spherulite structure formed in the course of nylon 6 fiber formation have been investigated. The dimensions and shape of the spherulites were determined by small‐angle scattering of polarized light with a simultaneous check by microscopy. Subsequent deformation at room temperature of the threads containing spherulites embedded in the amorphous glass‐like matrix causes the development and relaxation of stresses in the matrix. At this stage of elongation the spherulites themselves are “flattened” owing to the destruction of regions coinciding with the drawing direction. When the elongation exceeds X2.0 spherulite deformation sets in; it ends with the transition spherulite macrofibril. In the cross sections of the deformed samples spherulite‐like scattering and extinction patterns are observed up to sample rupture. This confirms that there is a direct genetic connection between the spherulite and orientational supermolecular order and indicates that the polarizability ellipsoids in the macrofibril exhibit complex distribution.
