Small-angle X-ray Scattering (SAXS) patterns are useful for studying the organization of crystalline and amorphous regions that make up a semi-crystalline polymer and influence its properties. To understand how these patterns originate and evolve dur

Semicrystalline polymers aligned by drawing into films or fibers produce small-angle X-ray scattering patterns with two or four spots. Some liquid crystalline materials, cybotactic nematics, produce extremely similar patterns when oriented in magneti

Small-angle X-ray and neutron scattering from materials with fibrous texture generally includes a central diffuse scattering that is either diamond-shaped or shaped like a two-bladed propeller. The central scattering from fibers of polyacrylonitrile,

Structural changes during tensile deformation in semicrystalline polymers are studied by the analysis of both small- and wide-angle X-ray scattering data from polyamide-6 fibers. The strain in the lamellar spacing is about the same as or higher than

The intensity maxima of lamellar reflections in small-angle scattering patterns from uniaxially oriented polymers such as fibers do not generally fall on a straight layer line or on a circular arc....

The fibrillar and the lamellar structures in a range of poly(ethylene terephthalate) fibers were studied by small-angle X-ray scattering. The intensity maxima in the lamellar peaks lie on a curve that can be described as an ellipse. Therefore, the tw
