Rayon fiber cross section
WebLyocell fiber has a close to circular cross-section (Figure 4.8). Its longitudinal surface is very smooth and cylindrical without any striation (Figure 4.9). Lyocell rayon fiber is different … Web-Rayon and acetate have striations and irregular cross sections-lyocell more rounded and smoother-rayon and lyocell burn like cotton or flax-acetate burns freely melts and decomposes to black char-Solubility is an easy way to identify acetate-acetone test is specific for acetate since none of the other fibers dissolves in acetone
