Abstract
By using commercial cellulosic fibers of Tencel®, Tencel A-100® and Polynosic, we tried to offer a novel technique giving not only a structural contrast in optical microscopic observations for the fiber in water but also the reflective swollen surface structure in electron microscopic observations for the dried fibers after swelling. Formation of colloidal particles on the swollen fiber surface was very effective for the purpose and exhibited similar characteristic structure in optical and electron microscopic observations.
