Crystallite orientation in wool fibers

WebNov 10, 2024 · Crystallites are grouped into microfibrils that, in turn, are clustered into sheet-like structures that wrap around the lumen or vacuole at various angles. These layers of primary wall sheets are themselves surrounded by a winding layer, the primary wall, and a cuticle. This chapter focuses on X-ray diffraction to interpret cotton fiber structure.

WebWe performed a small angle X-ray scattering (SAXS) study on fully mineralized human dentin to quantify this fiber/mineral composite architecture from the nanoscopic through continuum length scales. The SAXS results were consistent with nucleation and growth of the apatite phase within periodic gaps in the collagen fibers. WebInspired by the ordered β-sheet crystalline structure and molecular orientation of natural silkworm silk, biomimetic silk fibers with refined crystalline structure were creatively produced through incorporating cellulose nanocrystals (CNCs) into silk fibroin (SF) matrix to mimic the β-sheet crystallites in natural silk via wet-spinning assembly technology.

WebAs it can be seen from Table 3.2, wood fibers show lower cellulose crystallinity than natural plant fibers, with typical values in the ranges of 55–70% and 60–70%, respectively. Also, the crystallinity values increased upon partial delignification of natural plant fiber and alkaline peroxide bleaching. WebJul 1, 2024 · As the fiber develops, the crystallinity, crystallite size, and orientation in cellulose change.
