Abstract Ribbon‐like lamellar single crystals of cellulose II are grown from dilute aqueous solution of cellulose triacetate (number‐average degree of polymerization (DP)‐15) by deacetylation and consequent precipitation. The best results are obtained with methylamine as the deacetylation reagent at 90°C. Electron diffraction indicates the (1 1 0) planes to be the growth face. Twin growth occurs frequently with (1 1 0) as the twinning plane.
