•Roselle fiber-Microcrystalline cellulose (R-MCC) extracted by chemical process.•R-MCC demonstrates altered and non-uniform shape of micro-sized fibrils.•The unsymmetrical broad size distribution can be observed for R-pulp and R-MCC.•Crystallinity value of R-MCC (78%) is more than Commercial MCC (74...
